Value of Case-Based Learning within STEM Courses: Is It the Method or Is It the Student?

Integrated Case-Based Learning Session for Breast and Upper Limb Anatomy

Introduction

Medical students are frequently introduced to medical school curricula through anatomy coursework, which often includes histology and embryology content. As medical education has increasingly emphasized integration of content areas, use of activities such as case-based learning (CBL) sessions has grown. Little published work has demonstrated the effectiveness of CBL sessions in integrating anatomy, embryology, and histology on first-year medical students' ability to improve content mastery and adapt their study techniques.

Methods

We developed a CBL session that included anatomy, embryology, and histology content covering the upper extremity and breast pathology that was taught to incoming first-year medical students (N = 51) during a prematriculation program in the summers of 2022 and 2023. The session involved completion of an individual pre- and postsession quiz; group completion of clinical cases involving image interpretation, matching exercises, and construction of diagrams, flowcharts, or tables; and a postsession survey with Likert-style and free-response questions about preparation and session effectiveness.

Results

Postsession quiz scores significantly improved (p < .001). On the postsession survey (response rate: 59%), students commented that they enjoyed the real-life application and integration of the cases and that the sessions improved their understanding of the connections between content areas. Other comments demonstrated that students were evaluating and adapting their study approach in preparation for the sessions, often using techniques introduced and practiced in the sessions.

Discussion

CBL sessions can provide opportunities to incoming first-year medical students to practice, adapt, and evaluate study techniques while delivering integrated content.

Teaching science with the "universal language" of music: alignment with the Universal Design for Learning framework

The idea of teaching science through music has undeniable appeal in implying that learning can be engaging and fun while also covering content efficiently. Indeed, there is little doubt that songs can be uniquely memorable, suggesting mnemonic options for core content. However, many classroom implementations of science music have limitations such as an overemphasis on rote memorization, rather than a constructivist building of understanding. In this brief review, we ask how music might facilitate the learning of science content in a manner consistent with the well-known pedagogical framework of Universal Design for Learning (UDL). In our view, UDL suggests certain distinct possible benefits of incorporating music into curricula, leading us to propose four models of practice. These four models are as follows: 1) students enjoy music together, 2) students critically analyze songs as texts, 3) students creatively augment existing songs, and 4) students create new songs. Model 1 can contribute to an inclusive learning environment, while models 2-4 can encourage cognitively rich active learning, and models 3-4 can additionally help students channel scientific understanding into the creation of authentic products. We conclude with comments on logistical issues that arise in implementing these four models, including the use of appropriate rubrics and the prioritization of artistic quality.NEW & NOTEWORTHY Instructors and students often find it fun to incorporate music into science classes. However, the casual usage of music in this context can unintentionally convey that science courses are mostly about memorizing scientific facts. In this article, the authors argue for a more nuanced approach to teaching science with music, rooted in Universal Design for Learning (UDL).

Reading Primary Scientific Literature: Approaches for Teaching Students in the Undergraduate STEM Classroom

Teaching undergraduate students to read primary scientific literature (PSL) is cited as an important goal for many science, technology, engineering, and math (STEM) classes, given a range of cognitive and affective benefits for students who read PSL. Consequently, there are a number of approaches and curricular interventions published in the STEM education literature on how to teach students to read PSL. These approaches vary widely in their instructional methods, target student demographic, required class time, and level of assessment demonstrating the method's efficacy. In this Essay, we conduct a systematic search to compile these approaches in an easily accessible manner for instructors, using a framework to sort the identified approaches by target level, time required, assessment population, and more. We also provide a brief review of the literature surrounding the reading of PSL in undergraduate STEM classrooms and conclude with some general recommendations for both instructors and education researchers on future areas of investigation.

The effectiveness of problem-based learning compared with lecture-based learning in surgical education: a systematic review and meta-analysis

BACKGROUND

This meta-analysis was conducted to systematically evaluate the impact of problem-based learning (PBL) and lecture-based learning (LBL) teaching models on students' learning in surgical education.

METHODS

We systematically searched the publications related to the application of PBL and LBL in surgical courses in PubMed, Embase, Web of Science and Cochrane Library databases, the last retrieval time is September 20, 2022. After screening the literature according to the inclusion and exclusion criteria, extracting data and evaluating the methodological treatment of the included studies, Stata 17.0 software was used to perform meta-analysis.

RESULTS

Nine studies were included totally. The results showed that compared with LBL, PBL was superior in clinical competence (SMD = 0.81, 95% CI: 0.12 ~ 1.49, P = 0.020) and student satisfaction (SMD = 2.13, 95% CI: 1.11 ~ 3.15, P < 0.0001) with significant differences. But the comprehensive scores (SMD = 0.26, 95% CI: -0.37 ~ 0.89, P = 0.421) and theoretical knowledge (SMD=-0.19, 95% CI: -0.71 ~ 0.33, P = 0.482) to PBL and LBL had no significant difference.

CONCLUSION

This study showed that the PBL teaching model is more effective than the LBL teaching model in surgical education on the aspects of enhancing clinical competence and student satisfaction. However, further well-designed studies are needed to confirm our findings.

Are preprofessional undergraduate students ready for authentic clinical case studies? An empirical study of students' perceived relevance and motivation

Increasingly, the curricula of many clinical programs have been restructured to an integrated model in which foundational sciences such as physiology, pathophysiology, and pharmacology are taught side by side with clinical reasoning. Case studies are an excellent pedagogical strategy for enhancing such integration, especially if such cases are authentic, that is, they include a broad range of information that could influence the individualization and optimization of patient care. However, authentic cases may be too advanced and thereby dissuade preclinical students. We offered an optional semester-long authentic pharmacotherapy case study to undergraduate students in an introductory pharmacology class in a liberal arts college in the United States Midwest and sought to know what might motivate students to complete this challenging task. Connection with and relevance of the case study were assessed with an anonymous survey. Open-ended questions were analyzed qualitatively. Exploratory factor analysis and nonmetric multidimensional scaling were employed to investigate underlying commonalities and patterns in the motivations for participating in and relating to the case study. Students were motivated more by the perceived relevance and transferability of knowledge acquired to their future career than by their current clinical technician jobs or their personal lives. Rather than causing an information overload and dissuading students, this complex pharmacotherapy case assignment harnessed preclinical students' experiences from cognate cocurricular activities, created numerous points of relevant engagement with instructional content, and therefore motivated students to deeper learning.NEW & NOTEWORTHY Early introduction to clinical reasoning is widely advocated. Case studies are frequently used to enhance integration of foundational sciences with clinical reasoning. Preclinical students may be overwhelmed by complex cases because of the higher-order cognitive tasks involved. We find that complex cases permit connection with students' own experiences and aspirations. These preclinical students were motivated to engage in such challenging academic work because of the perceived transferability of knowledge to their future careers.

The Value of CBL-Based Teaching Mode in Training Medical Students' Achievement Rate, Practical Ability, and Psychological Quality

In order to improve the quality of medical student training, the clinical case-based learning (CBL) teaching mode is analyzed in the aspect of the rate of achievement, practical ability, and psychological effect. A total of 86 medical students who came to our hospital from March 2020 to December 2021 are selected and divided into the CBL group and the control group according to the random number table method. The psychological quality of medical students is evaluated by observing their movements and expressions during their internship. In addition, the questionnaire is used to evaluate the scores of a medical student in future planning, occupational health, and teamwork spirit. The compliance evaluation results show that CBL teaching mode can significantly improve the compliance rate of medical students in training and promote the confidence of future role change to a certain extent.

Comparison of case-based learning combined with Rain Classroom teaching and traditional method in complete denture course for undergraduate interns

BACKGROUND

Complete denture, as an important restoration method for edentulism, is difficult to study for beginners, especially in linking the theory with clinical practice.

OBJECTIVE

This study was aimed to compare the teaching effects between case-based learning combined with Rain Classroom teaching and traditional lecture method in the clinical course of complete denture prosthesis for undergraduate interns.

METHODS

In a course called "Problems and treatment strategies of complete denture after wearing", interns were divided into two groups: one for traditional lecture-based teaching with PowerPoint slideshow (the control group, n = 28); and the other for case-based learning combined with Rain Classroom teaching, which published information before class, discussed specific clinic cases in class and got real-time interns' feedback via WeChat (the test group, n = 22). Both groups received the same exam and questionnaire survey after class. The Q&A participation of interns in class, theoretical test scores and questionnaire survey responses were used to evaluate the teaching effects. An independent sample t-test and the chi-square test or Fisher's exact test were used for statistical analysis in this study.

RESULTS

The Q&A participation of interns in the test group was much better than that of the control group. The average score on the theoretical test after class in the test group (72.14 ± 12.24) was significantly higher than that in the control group (61.29 ± 20.12) (P < 0.05). In the test group, 94.54% (21/22) of the interns preferred the new teaching mode.

CONCLUSION

Case-based learning combined with Rain Classroom teaching is helpful to enliven the classroom atmosphere, inspire studying enthusiasm, and achieve a good learning effect in both theory and clinical practice related to complete denture prosthesis.

Application of online case-based learning in the teaching of clinical anesthesia for residents during the COVID-19 epidemic

OBJECTIVE

COVID-19 prevention and control demand a reduction in crowd gathering, which has a significant impact on traditional teaching and offline case-based learning (CBL). In order to mitigate the impact of the COVID-19 outbreak on clinical teaching, we aimed to compare the effects of an online CBL with traditional teaching model on learning outcomes of anesthesia residents.

METHODS

Residents rotated in the Department of Anesthesiology in Beijing Tsinghua Changgung Hospital from January 2020 to February 2021 were included in Group W (n = 19), which implemented the W-CBL teaching model. The performance of residents was evaluated with theory test and 2 survey questionnaires (A and B) were conducted after 1 month of rotating. All 20 residents rotating in the Department of Anesthesiology at our hospital from January 2018 to December 2019 were included in Group C, which implemented the traditional teaching model. Their examination results were acquired through the teaching files and survey questionnaire (A) were administered through WeChat.

RESULTS

During the 1-month rotation, a total of 10 cases were discussed in Group W. The average score for theory test was higher in Group W than that in Group C (84.57 ± 4.87 vs. 79.35 ± 3.70, P = 0.001). The satisfaction rate was also in favor of Group W regarding to clinical thinking, communication skills, learning interest and self-learning ability (P < 0.05).

CONCLUSIONS

Online CBL based on WeChat platform is an effective and acceptable teaching strategy in comparison to lecture-based learning (LBL) among residents embarking on clinical anesthesia courses.
