Active learning narrows achievement gaps for underrepresented students in undergraduate science, technology, engineering, and math

Instructor Strategies to Alleviate Stress and Anxiety among College and University STEM Students

While student stress and anxiety are frequently cited as having negative effects on students' academic performance, the role that instructors can play in mitigating these challenges is often underappreciated. We provide summaries of different evidence-based strategies, ranging from changes in instructional strategies to specific classroom interventions, that instructors may employ to address and ameliorate student stress and anxiety. While we focus on students in science, technology, engineering, and mathematics, the strategies we delineate may be more broadly applicable. We begin by highlighting ways in which instructors can learn about and prepare to act to alleviate stress and anxiety. We then discuss how to better connect with students and build an inclusive, equitable, and empowering classroom environment. When coupled with strategies to change student evaluation and assessment, these approaches may collectively reduce student stress and anxiety, as well as improve student performance. We then discuss the roles that instructors may play in empowering students with skills that improve their time management, studying, and approach toward learning, with an eye toward ensuring their success across all their academic endeavors. We conclude by noting areas in which further research is needed to determine best practices for alleviating student stress and anxiety.

"I Like and Prefer to Work Alone": Social Anxiety, Academic Self-Efficacy, and Students' Perceptions of Active Learning

Although active learning improves student outcomes in science, technology, engineering, and mathematics (STEM) programs, it may provoke anxiety in some students. We examined whether two psychological variables, social anxiety (psychological distress relating to the fear of negative evaluation by others) and academic self-efficacy (confidence in one's ability to overcome academic challenges), interact with student perceptions of evidence-based instructional practices (EBIPs) and associate with their final grades in a STEM-related course. Human anatomy and physiology students in community college courses rated various EBIPs for their perceived educational value and their capacity to elicit anxiety (N = 227). In general, practices causing students the most anxiety (e.g., cold calling) were reported by students as having the least educational value. When controlling for students' self-reported grade point averages, socially anxious students rated several EBIPs as more anxiety inducing, whereas high-efficacy students reported less anxiety surrounding other EBIPs. Furthermore, mediation analysis revealed that individual differences in academic self-efficacy at the beginning of the term explained some of the negative association between students' social anxiety levels and final grades in the course. Our results, obtained in a community college context, support a growing body of evidence that social anxiety and academic self-efficacy are linked with how students perceive and perform in an active-learning environment.

Christianity as a Concealable Stigmatized Identity (CSI) among Biology Graduate Students

Recent research has begun to explore the experiences of Christian undergraduates and faculty in biology to illuminate reasons for their underrepresentation. In this study, we focused on the experiences of graduate students and explored Christianity as a concealable stigmatized identity (CSI) in the biology community. We constructed interview questions using this CSI framework, which originates in social psychology, to research the experiences of those with stigmatized identities that could be hidden. We analyzed interviews from 33 Christian graduate students who were enrolled in biology programs and found that many Christian graduate students believe the biology community holds strong negative stereotypes against Christians and worry those negative stereotypes will be applied to them as individuals. We found that students conceal their Christian identities to avoid negative stereotypes and reveal their identities to counteract negative stereotypes. Despite these experiences, students recognize their value as boundary spanners between the majority secular scientific community and majority Christian public. Finally, we found that Christian students report that other identities they have, including ethnicity, gender, nationality, and LGBTQ+ identities, can either increase or decrease the relevance of their Christian identities within the biology community.

What really impacts the use of active learning in undergraduate STEM education? Results from a national survey of chemistry, mathematics, and physics instructors

Six common beliefs about the usage of active learning in introductory STEM courses are investigated using survey data from 3769 instructors. Three beliefs focus on contextual factors: class size, classroom setup, and teaching evaluations; three focus on individual factors: security of employment, research activity, and prior exposure. The analysis indicates that instructors in all situations can and do employ active learning in their courses. However, with the exception of security of employment, trends in the data are consistent with beliefs about the impact of these factors on usage of active learning. We discuss implications of these results for institutional and departmental policies to facilitate the use of active learning.

Inclusion in neuroscience through high impact courses

Recognizing that STEM disciplines, including neuroscience, have a long way to go to attract and retain diverse talent, educators can take action by being more intentional about their departmental curricula, course design, and pedagogical strategies. A deep body of research suggests that one way we can promote inclusion is through the use of high impact practices (HIPs). These active learning teaching practices promote deep learning and student engagement and have been shown to have a positive differential impact on historically underserved student populations. Here we describe the characteristics of two different types of HIP courses, makerspace classes, and course-based undergraduate research experiences (CUREs). In addition, we provide ideas for how these courses can be structured to help all students engage and learn. With experience overseeing a large campus-wide program introducing these course types to the curriculum, we also provide insights about faculty experiences and assessment. We propose that including these types of courses in a curriculum can engage a more diverse group of students to choose neuroscience as a major and as a career.

Tiny Earth: A Big Idea for STEM Education and Antibiotic Discovery

The world faces two seemingly unrelated challenges-a shortfall in the STEM workforce and increasing antibiotic resistance among bacterial pathogens. We address these two challenges with Tiny Earth, an undergraduate research course that excites students about science and creates a pipeline for antibiotic discovery.

Improving Undergraduate Epidemiology Education: An Example Using Instructional Teams

Epidemiology is a core component of the undergraduate public health curriculum and a critical component of a healthy community and a comprehensive education. Evidence-based, collaborative instructional practices improve student success, reach diverse student populations, and improve learning outcomes. Here we describe the pedagogical approach of an instructional team with which we observed an 18% greater learning gain (95% confidence interval: 6.5, 29.5; t = -3.08; P = 0.002), based on pre-/posttesting in a large (approximately 120 students) undergraduate course, than with the prior course offering. There were no differences in DEW rates (defined as receiving a grade of D (scoring 60%-69%) or E (scoring <60%) or withdrawing (W)) between the 2 offerings, but the ratio of "A" to "B" grades was higher (by approximately 10%) after deployment of the instructional team (Pearson's χ2 (1 degree of freedom) = 4.17, P = 0.041). In addition, students reported greater satisfaction with the course deploying an instructional team (80.4% positive sentiment in course evaluation comments compared with 76.1% in the prior offering). As students and faculty become more familiar with effective evidence-based instructional practices, improvements in student learning can be achieved and the goal of creating an educated citizenry ready to build a healthy society will be more attainable.

A Multimedia Active Learning Approach to Introducing Human Parasitic Diseases in an Undergraduate Parasitology Course

Introducing undergraduate students to major human diseases is a key focus of many parasitology courses. Here I present a multifaceted active learning technique that familiarizes students with major human parasitic diseases while simultaneously exposing students to a range of important medical, biological, and ecological concepts.

Using Virtual Simulations in Online Laboratory Instruction and Active Learning Exercises as a Response to Instructional Challenges during COVID-19

The onset of the COVID-19 pandemic in the spring of 2020 thrust instructors into a world of frenzy, presenting unique challenges to delivering course content. A particular challenge was determining suitable substitutes for wet lab experiments that are often comprised in science labs. Recognizing that this problem was not short-term, I started to look into virtual substitutions to be implemented in the 2020-2021 academic year. Virtual simulations can replace labs, be incorporated as pre-lab assignments, or used as active-learning or experiential learning exercises in a traditional classroom setting while providing low-cost, safe, and acceptable solutions to the current problem. Virtual simulations were examined on different platforms, including Labster, McGraw Hill Connect Virtual Labs, HHMI BioInteractive, Learn.Genetics, Virtual Interactive Bacteriology Laboratory, and Biology Corner. The goal was to provide faculty around the world with a reference list of virtual simulations that are aligned to specific AAAS and ASM student learning outcomes. These simulations are discussed in terms of content, features, and advantages of use. A list of lab exercises aligned to biology courses (microbiology, genetics, and cell biology) is also provided.

The doctrine of normal tendency in active learning teaching methodology: investigations into probability distributions and averages

Traditional lecture and active learning methods of teaching a university course are compared. The particular course is university calculus. The lecture method was applied to two sections of calculus. The active learning method was applied to two other sections. In all cases students were given an examination near the beginning of the course and a final examination at the end of the course. The score averages for the active learning method were higher than for the lecture method. The distribution of scores for the lecture method were non-normal multimodal in the first and final examinations. The distribution for the active learning method went from non-normal multimodal in the first examination to unimodal normal in the final examination. A new undeceivable nature evidence-based method is presented for measuring teaching efficacy by probability distribution.

Integrating Research into the Undergraduate Curriculum: 2. Scaffolding Research Skills and Transitioning toward Independent Research

Undergraduate research experiences are widely regarded as high-impact practices that foster meaningful mentoring relationships, enhance retention and graduation, and stimulate postbaccalaureate enrollment in STEM graduate and professional programs. Through immersion in a mentored original research project, student develop and apply their skills in critical thinking, problem solving, intellectual independence, communication, collaboration, project ownership, innovation, and leadership. These skills are readily transferable to a wide array of future careers in and beyond STEM that are well-served by evidence-based approaches. The 2019 Society for Neuroscience meeting included a well-attended workshop on integrating research into the curriculum at primarily undergraduate institutions (PUIs). This article is the second of three articles that summarize, analyze, and expand the workshop discussions. In this second article, we specifically describe approaches to transitional research courses that prepare students for independent research experiences such as undergraduate research theses. Educators can intentionally scaffold research experience and skills across the curriculum, to foster participation in scientific research and enhance diversity, equity, and inclusivity in research training. This article provides an overview of important goals and considerations for intermediate undergraduate research experiences, specific examples from several institutions of transitional courses that scaffold research preparation using different structures, and a summary of lessons learned from these experiences.

Integrating Research into the Undergraduate Curriculum: 1. Early Research Experiences and Training

Undergraduate research experiences have emerged as some of the most beneficial high-impact practices in education, providing clear benefits to students that include improved critical thinking and scientific reasoning, increased academic performance, and enhanced retention both within STEM majors and in college overall. These benefits extend to faculty members as well. Several disciplines, including neuroscience, have implemented research as part of their curriculum, yet many research opportunities target late stage undergraduates, despite evidence that early engagement can maximize the beneficial nature of such work. A 2019 Society for Neuroscience professional development workshop provided multiple examples of integrating research into an undergraduate curriculum, including early engagement (Fernandes, 2020). This article is the first in a series of three that expands upon the information presented in those workshop discussions, focusing on ways to promote early research opportunities. The benefits and challenges associated with early research engagement suggest thoughtful consideration of the best mechanisms for implementation are warranted; some options might include apprenticeship models or course-based approaches. Regardless of mechanism, early research can serve to initiate more prolonged, progressive, scaffolded experiences that span the academic undergraduate career.

Integrating Research into the Undergraduate Curriculum: 3. Research Training in the Upper-level Neuroscience Curriculum

The benefits of undergraduate training in research are significant. Integration of such training into the undergraduate experience, however, can be challenging at institutions without extensive research programs, and may inadvertently exclude some populations of students. Therefore, inclusion of research into the academic curriculum ensures all students can access this important training. The 2019 annual meeting of the Society for Neuroscience included a workshop on integrating research into the curriculum at primarily undergraduate institutions (PUIs). In this last article of a three-part series, we describe models for integrating research into advanced stages of the undergraduate curriculum, specifically for juniors and seniors. First, we describe multiple models of faculty-mentored group-based research. Second, we detail a peer-mentored research system, in which seniors mentor groups of first through third year students. Third, we describe multiple examples of integrating research into "capstone" courses for seniors. Fourth, we describe models in which a senior thesis is a graduation requirement for all students. Lastly, we describe several models of implementing an optional honors thesis for students. Although similarities exist across these programs, their differences allow for specific secondary objectives to be met, which are often unique to institutions and/or departments. Therefore, for each of these examples, we describe the context, specific design, and required student assessments. We conclude by discussing some of the key successes and challenges of developing programs that facilitate undergraduate research by upper-level students, and suggest a number of concepts that should be considered by individuals developing and assessing new programs.

Online biology degree program broadens access for women, first-generation to college, and low-income students, but grade disparities remain

Online education has grown rapidly in recent years with many universities now offering fully online degree programs even in STEM disciplines. These programs have the potential to broaden access to STEM degrees for people with social identities currently underrepresented in STEM. Here, we ask to what extent is that potential realized in terms of student enrollment and grades for a fully online degree program. Our analysis of data from more than 10,000 course-enrollments compares student demographics and course grades in a fully online biology degree program to demographics and grades in an equivalent in-person biology degree program at the same university. We find that women, first-generation to college students and students eligible for federal Pell grants constitute a larger proportion of students in the online program compared to the in-person mode. However, the online mode of instruction is associated with lower course grades relative to the in-person mode. Moreover, African American/Black, Hispanic/Latinx, Native American, and Pacific Islander students as well as federal Pell grant eligible students earned lower grades than white students and non-Pell grant eligible students, respectively, but the grade disparities were similar among both in-person and online student groups. Finally, we find that grade disparities between men and women are larger online compared to in-person, but that for first-generation to college women, the online mode of instruction is associated with little to no grade gap compared to continuing generation women. Our findings indicate that although this online degree program broadens access for some student populations, inequities in the experience remain and need to be addressed in order for online education to achieve its inclusive mission.

Improving Instructional Fitness Requires Change

Transmission of information has benefitted from a breathtaking level of innovation and change over the past 20 years; however, instructional methods within colleges and universities have been slow to change. In the article, we present a novel framework to structure conversations that encourage innovation, change, and improvement in our system of higher education, in general, and our system of biology education, specifically. In particular, we propose that a conceptual model based on evolutionary landscapes in which fitness is replaced by educational effectiveness would encourage educational improvement by helping to visualize the multidimensional nature of education and learning, acknowledge the complexity and dynamism of the educational landscape, encourage collaboration, and stimulate experimental thinking about how new approaches and methodology could take various fields associated with learning, to more universal fitness optima. The framework also would encourage development and implementation of new techniques and persistence through less efficient or effective valleys of death.

Biosensors Show Promise as a Measure of Student Engagement in a Large Introductory Biology Course

This study measured student engagement in real time through the use of skin biosensors, specifically galvanic skin response (GSR), in a large undergraduate lecture classroom. The study was conducted during an intervention in an introductory-level biology course (N = 420) in which one section of the course was taught with active-learning approaches and the other with traditional didactic teaching. GSR results were aligned and correlated with the Classroom Observation Protocol for Undergraduate STEM, or COPUS, and student self-reflections on their own engagement. Results showed that the active-learning section spent more time working in groups, resulting in GSR measures that trended higher and self-reported engagement, while showing indications of higher content learning gains compared with the traditional lecture section. Comparisons between COPUS scores and GSR readings indicate that engagement increased during group work and decreased during listening activities. Throughout a class period, GSR activity of the active-learning group showed increased trends compared with baseline measures, while the traditional lecture group showed decreased trends. Results indicate that GSR is a promising measure of real-time student engagement in the undergraduate classroom, bringing a new technique to discipline-based education researchers who aim to better measure student engagement; however, some limitations exist for broad-scale implementation.

Demystifying the Meaning of Active Learning in Postsecondary Biology Education

Active learning is frequently used to describe teaching practices, but the term is not well-defined in the context of undergraduate biology education. To clarify this term, we explored how active learning is defined in the biology education literature (n = 148 articles) and community by surveying a national sample of biology education researchers and instructors (n = 105 individuals). Our objectives were to increase transparency and reproducibility of teaching practices and research findings in biology education. Findings showed the majority of the literature concerning active learning never defined the term, but the authors often provided examples of specific active-learning strategies. We categorized the available active-learning definitions and strategies obtained from the articles and survey responses to highlight central themes. Based on data from the BER literature and community, we provide a working definition of active learning and an Active-Learning Strategy Guide that defines 300+ active-learning strategies. These tools can help the community define, elaborate, and provide specificity when using the term active learning to characterize teaching practices.

Is Active Learning Accessible? Exploring the Process of Providing Accommodations to Students with Disabilities

On average, active learning improves student achievement in college science courses, yet may present challenges for students with disabilities. In this essay, we review the history of accommodating students with disabilities in higher education, highlight how active learning may not always be inclusive of college science students with disabilities, and articulate three questions that could guide research as the science community strives to create more inclusive environments for undergraduates with disabilities: 1) To what extent do stakeholders (disability resource center [DRC] directors, instructors, and students) perceive that students with disabilities encounter challenges in active learning? 2) What accommodations, if any, do stakeholders perceive are being provided for students with disabilities in active learning? and 3) What steps can stakeholders take to enhance the experiences of students with disabilities in active learning? To provide an example of how data can be collected to begin to answer these questions, we interviewed 37 DRC directors and reported what challenges they perceive that students with disabilities experience in active learning and the extent to which accommodations are used to alleviate challenges. We conclude the essay with a suite of recommendations to create more inclusive active-learning college science classes for students with disabilities.

A Call for Data-Driven Networks to Address Equity in the Context of Undergraduate Biology

National efforts to improve equitable teaching practices in biology education have led to an increase in research on the barriers to student participation and performance, as well as solutions for overcoming these barriers. Fewer studies have examined the extent to which the resulting data trends and effective strategies are generalizable across multiple contexts or are specific to individual classrooms, institutions, or geographic regions. To address gaps in our understanding, as well as to establish baseline information about students across contexts, a working group associated with a research coordination network (Equity and Diversity in Undergraduate STEM, EDU-STEM) convened in Las Vegas, Nevada, in November of 2019. We addressed the following objectives: 1) characterize the present state of equity and diversity in undergraduate biology education research; 2) address the value of a network of educators focused on science, technology, engineering, and mathematics equity; 3) summarize the status of data collection and results; 4) identify and prioritize questions and interventions for future collaboration; and 5) construct a recruitment plan that will further the efforts of the EDU-STEM research coordination network. The report that follows is a summary of the conclusions and future directions from our discussion.

Undergraduate neuroscience education: Meeting the challenges of the 21st century

The dedication of undergraduate neuroscience faculty to their students could not have been more evident than what these educators demonstrated when the COVID-19 pandemic impacted colleges and universities across the United States. These faculty faced the crisis head-on to provide their students with exceptional instruction in virtual formats that many faculty had never used for instruction before the pandemic. This same tenacious attitude has been reflected in pedagogical efforts that undergraduate neuroscience faculty have undertaken since the mid-1990s. The challenges of providing cutting-edge neuroscience education to undergraduates in a dynamic field have produced a series of curricular designs and approaches that capitalize on discipline-based education research. This article reviews curricular models and pedagogical strategies aimed at enhancing the educational experiences of undergraduate neuroscience students whose lived experiences and academic backgrounds reflect the richly kaleidoscopic demographics of college students in the 21st century. The future of undergraduate neuroscience education is bright as faculty and their students collaborate on their journey of discovery in neuroscience.

Facilitating Long-Term Mentoring To Effectively Implement Active Learning Instruction: Formation of the Promoting Active Learning and Mentoring (PALM) Network

A large body of data suggests that implementing active learning practices in a STEM classroom contributes to increased success in both achievement of student learning outcomes and retention of students. Despite these findings, significant barriers exist for instructors implementing active learning strategies in their undergraduate classrooms. These barriers can be effectively addressed by providing sustained support to instructors and postdoctoral trainees interested in implementing active learning strategies in their teaching practice. The Promoting Active Learning and Mentoring (PALM) network attains this objective by connecting instructors interested in learning more about active learning (Fellows) with individuals who have extensive expertise related to this practice (mentors). These facilitated connections occur in the form of active mentorship for a year or more, virtual journal clubs, and biannual gatherings of PALM Fellows and mentors. Here, we describe the foundation on which PALM was built and explain how a successful mentorship program can pave the way for educators to adapt and implement evidence-based practices like active learning in a college classroom.

Educational technologies on sexually transmitted infections for incarcerated women

OBJECTIVE

to analyze in the scientific literature the educational technologies on sexually transmitted infections used in health education for incarcerated women.

METHOD

an integrative review carried out by searching for articles in the following databases: Scopus, Cumulative Index of Nursing and Allied Health, Education Resources Information Center, PsycInFO, Medical Literature Analysis and Retrieval System Online, Latin American Literature in Health Sciences, Cochrane, and the ScienceDirect electronic library. There were no language and time restrictions. A search strategy was developed in PubMed and later adapted to the other databases.

RESULTS

a total of 823 studies were initially identified and, after applying inclusion and exclusion criteria, eight articles were selected. Most of them were developed in the United States with a predominance of randomized clinical trials. The technologies identified were of the printed materials type, isolated or associated to simulators of genital organs, videos, and games.

CONCLUSION

the technologies on sexually transmitted infections used in health education for incarcerated women may contribute to adherence to the prevention of this serious public health problem in the context of deprivation of liberty.

From panic to pedagogy: Using online active learning to promote inclusive instruction in ecology and evolutionary biology courses and beyond

The rapid shift to online teaching in spring 2020 meant most of us were teaching in panic mode. As we move forward with course planning for fall and beyond, we can invest more time and energy into improving the online experience for our students. We advocate that instructors use inclusive teaching practices, specifically through active learning, in their online classes. Incorporating pedagogical practices that work to maximize active and inclusive teaching concepts will be beneficial for all students, and especially those from minoritized or underserved groups. Like many STEM fields, Ecology and Evolution shows achievement gaps and faces a leaky pipeline issue for students from groups traditionally underserved in science. Making online classes both active and inclusive will aid student learning and will also help students feel more connected to their learning, their peers, and their campus. This approach will likely help with performance, retention, and persistence of students. In this paper, we offer broadly applicable strategies and techniques that weave together active and inclusive teaching practices. We challenge instructors to commit to making small changes as a first step to more inclusive teaching in ecology and evolutionary biology courses.

Leveraging public data to offer online inquiry opportunities

Inquiry activities have become increasingly common in Ecology and Evolution courses, but the rapid shift to remote instruction for many faculty members in response to the COVID-19 pandemic has created new challenges for maintaining these student-centered activities in a distance learning format. Moving forward, many instructors will be asked to create flexible course structures that allow for a mix of different teaching modalities and will be looking for resources to support student inquiry in both online and in-person settings. Here, we propose the use of data-driven inquiry activities as a flexible option for offering students experiences to build career-relevant skills and learn fundamental ecological concepts. We share lessons learned from our experiences teaching a two-semester course-based research experience in global change ecology that leverages publicly available datasets to engage students in broadly relevant scientific inquiry.

Innovative teaching knowledge stays with users

Programs seeking to transform undergraduate science, technology, engineering, and mathematics courses often strive for participating faculty to share their knowledge of innovative teaching practices with other faculty in their home departments. Here, we provide interview, survey, and social network analyses revealing that faculty who use innovative teaching practices preferentially talk to each other, suggesting that greater steps are needed for information about innovative practices to reach faculty more broadly.

Mathematical Biology: Expand, Expose, and Educate!

Mathematical biology has made significant contributions and advancements in the biological sciences. Recruitment efforts focus on encouraging students, especially those who are underrepresented and underserved, to pursue the field of mathematical biology, regardless of their undergraduate institution type, and raise awareness about the countless professional and academic possibilities provided by this specialized training. This article examines the need to expand, expose, and educate others about mathematical biology. To support field expansion, we give several recommendations of ways to integrate mathematics applied curricula to attract broader student interest. With this exposure-whether it is led by an individual, a department, a university, or researchers in mathematical biology-each can help to promote a base knowledge and appreciation of the field. In order to encourage the next generation of researchers to consider mathematical biology, we highlight current interdisciplinary programs, share popular mathematical tools, and present some thoughts on ways to support a thriving and inclusive mathematical biology community for years to come.

The Genetic Code Kit: An Open-Source Cell-Free Platform for Biochemical and Biotechnology Education

Teaching the processes of transcription and translation is challenging due to the intangibility of these concepts and a lack of instructional, laboratory-based, active learning modules. Harnessing the genetic code in vitro with cell-free protein synthesis (CFPS) provides an open platform that allows for the direct manipulation of reaction conditions and biological machinery to enable inquiry-based learning. Here, we report our efforts to transform the research-based CFPS biotechnology into a hands-on module called the “Genetic Code Kit” for implementation into teaching laboratories. The Genetic Code Kit includes all reagents necessary for CFPS, as well as a laboratory manual, student worksheet, and augmented reality activity. This module allows students to actively explore transcription and translation while gaining exposure to an emerging research technology. In our testing of this module, undergraduate students who used the Genetic Code Kit in a teaching laboratory showed significant score increases on transcription and translation questions in a post-lab questionnaire compared with students who did not participate in the activity. Students also demonstrated an increase in self-reported confidence in laboratory methods and comfort with CFPS, indicating that this module helps prepare students for careers in laboratory research. Importantly, the Genetic Code Kit can accommodate a variety of learning objectives beyond transcription and translation and enables hypothesis-driven science. This opens the possibility of developing Course-Based Undergraduate Research Experiences (CUREs) based on the Genetic Code Kit, as well as supporting next-generation science standards in 8–12th grade science courses.

Effectiveness of Using Voice Assistants in Learning: A Study at the Time of COVID-19

The use of advanced learning technologies in a learning management system (LMS) can greatly assist learning processes, especially when used in university environments, as they promote the development of Self-Regulated learning, which increases academic performance and student satisfaction towards personal learning. One of the most innovative resources that an LMS may have is an Intelligent Personal Assistant (IPA). We worked with a sample of 109 third-grade students following Health Sciences degrees. The aims were: (1) to verify whether there will be significant differences in student access to the LMS, depending on use versus non-use of an IPA. (2) To verify whether there will be significant differences in student learning outcomes depending on use versus non-use of an IPA. (3) To verify whether there will be significant differences for student satisfaction with teaching during the COVID-19 pandemic, depending on use versus non-use of an IPA. (4) To analyze student perceptions of the usefulness of an IPA in the LMS. We found greater functionality in access to the LMS and satisfaction with teaching, especially during the health crisis, in the group of students who had used an IPA. However, both the expansion of available information and the usability of the features embedded in an IPA are still challenging issues.

Psychotherapy in pain management: New viewpoints and treatment targets based on a brain theory

The current paper provides an explanation of neurophysiological pain processing based the Dimensional Systems Model (DSM), a theory of higher cortical functions in which the cortical column is considered the binary digit for all cortical functions. Within the discussion, novel views on the roles of the basal ganglia, cerebellum, and cingulate cortex are presented. Additionally, an applied Clinical Biopsychological Model (CBM) based on the DSM will be discussed as related to psychological treatment with chronic pain patients. Three specific areas that have not been adequately addressed in the psychological treatment of chronic pain patients will be discussed based on the CBM. The treatment approaches have been effectively used in a clinical setting. Conclusions focus on a call for researchers and clinicians to fully evaluate the value of both the DSM and CBM.

Adapting guided inquiry learning worksheets for emergency remote learning

Purpose

Process-oriented guided inquiry learning (POGIL) is a series of learning activities building on student prior knowledge guiding them to construct their own understanding of new concepts in collaborative roles. This paper aims to illustrate how POGIL worksheets can be adapted for low bandwidth and low-computing environments to accommodate the largest swathe of learners in higher education, as was the case during the switch to emergency remote learning in 2020.

Design/methodology/approach

The POGIL worksheets in this paper scaffold the discovery of new concepts while providing sample computer program output, guiding students to make predictions about the connection between program input and program output. Answers are provided to these questions after completion so that students may check their understanding or look to the answers as worked examples. These POGIL worksheets were used for the past two years in an in-person classroom situation with minimal computing resources, replacing 4/5 of a classroom lecture doing POGILs collaboratively. In the midst of emergency remote learning, these worksheets were adapted to complement asynchronous lecture videos, and also serve as lecture replacement as needed.

Findings

This paper discusses an approach to adapting POGIL worksheets for introduction to computer science for students who may not have the necessary digital tools (programing software, bandwidth for streaming video, etc.). While the context for this paper is computer science, POGIL has a deep history in chemistry education and other natural sciences, suggesting an approach that may be adapted for situations where hands-on laboratory experiments may not be possible.

Originality/value

CS-POGIL has many materials available for computer science, but this paper discusses 23 new worksheets and how to adapt them to the novel situation of emergency remote teaching.

Characterizing college science instruction: The Three-Dimensional Learning Observation Protocol

The importance of improving STEM education is of perennial interest, and to this end, the education community needs ways to characterize transformation efforts. Three-dimensional learning (3DL) is one such approach to transformation, in which core ideas of the discipline, scientific practices, and crosscutting concepts are combined to support student development of disciplinary expertise. We have previously reported on an approach to the characterization of assessments, the Three-Dimensional Learning Assessment Protocol (3D-LAP), that can be used to identify whether assessments have the potential to engage students in 3DL. Here we present the development of a companion, the Three-Dimensional Learning Observation Protocol (3D-LOP), an observation protocol that can reliably distinguish between instruction that has potential for engagement with 3DL and instruction that does not. The 3D-LOP goes beyond other observation protocols, because it is intended not only to characterize the pedagogical approaches being used in the instructional environment, but also to identify whether students are being asked to engage with scientific practices, core ideas, and crosscutting concepts. We demonstrate herein that the 3D-LOP can be used reliably to code for the presence of 3DL; further, we present data that show the utility of the 3D-LOP in differentiating between instruction that has the potential to promote 3DL from instruction that does not. Our team plans to continue using this protocol to evaluate outcomes of instructional transformation projects. We also propose that the 3D-LOP can be used to support practitioners in developing curricular materials and selecting instructional strategies to promote engagement in three-dimensional instruction.

Reducing achievement gaps in undergraduate general chemistry could lift underrepresented students into a "hyperpersistent zone"

Students from underrepresented groups start college with the same level of interest in STEM majors as their peers, but leave STEM at higher rates. We tested the hypothesis that low grades in general chemistry contribute to this "weeding," using records from 25,768 students. In the first course of a general chemistry series, grade gaps based on binary gender, race/ethnicity, socioeconomic status, and family education background ranged from 0.12 to 0.54 on a four-point scale. Gaps persisted when the analysis controlled for academic preparation, indicating that students from underrepresented groups underperformed relative to their capability. Underrepresented students were less likely than well-represented peers to persist in chemistry if they performed below a C-, but more likely to persist if they got a C or better. This "hyperpersistent zone" suggests that reducing achievement gaps could have a disproportionately large impact on efforts to achieve equity in STEM majors and professions.
