A systematic literature review of assessment feedback in preclinical dental education

Dental students' ability to judge the quality of composite restorations' exemplars depicted in photographs and their impact on preclinical skills

INTRODUCTION

Assessing exemplars as a formative activity is thought to promote students' learning. This study aimed to investigate dental students' ability to judge the quality of composite restorations' exemplars depicted in photographs and their impact on students' preclinical skills.

MATERIALS AND METHODS

In a non-randomised controlled crossover trial with two intervention arms, 92 undergraduates in their first preclinical course self-enrolled in into the intervention group (A1-INT) or control group (B1-CT). The intervention group assessed photographic images of composite restorations before restoring an ivorine premolar with composite while the control group restored the same tooth without assessing the photographic exemplars. Intervention and control groups were swapped 3 days later in a second iteration (B2-INT, A2-CT). Data were analysed in SPSS® version 27 using nonparametric tests.

RESULTS

Students who did not complete all activities in the study were excluded. Therefore, 57 out of the 92 student participants were included in the study analysis. No significant differences were observed between intervention and control groups' ability to assess quality of photographic exemplars or restoring a tooth in both iterations.

CONCLUSION

Students were able to identify the quality of composite restorations in photographic exemplars. It appears that assessing photographic exemplars did not have an immediate impact on students' ability to restore a tooth with composite.

Association between stereoacuity and simulated clinical performance among dental students: an exploratory investigation

INTRODUCTION

Dentistry is a profession that requires a high level of the hand-eye coordination. Although considerable attention has been put on dental students' manual dexterity, little emphasis was made on students' visual competency as a variable influencing their competency. In this study, we aimed to assess the association between dental students' stereopsis and their pre-clinical performance.

METHODS

Dental students (n = 49) were required to perform the porcelain-fused-to-crown preparation for a lower first molar and an upper central incisor plastic teeth mounted on phantom heads. Performance was assessed by two faculty members based on two rubrics, which collectively included 11 assessment criteria. Afterward, students undertook a stereoacuity test using Randot stereotest. Stereopsis values greater than 40 arc/s were considered abnormal.

RESULTS

A significant negative correlation was seen between stereopsis scores and students' grades for the upper incisor (p < 0.01), but not for the lower molar. An association was also seen between abnormal stereopsis and students' poor performance in preparing the finish line of the incisor tooth (p = 0.024).

CONCLUSION

Abnormal stereopsis can impact dental students' performance, particularly when preparing teeth indirectly using a dental mirror. Dental educators should give attention to students' stereoacuity, in a manner similar to that given to students' manual dexterity.

Dental Teacher Feedback and Student Learning: A Qualitative Study

INTRODUCTION

Feedback is essential to improve student learning and motivation and to encourage curriculum development by teachers. This study looked at feedback to and from dental students from a qualitative perspective.

METHODS

Dental teachers were recruited exclusively to this study from the membership of the Association for Dental Education in Europe (ADEE). Delegates from each of the four annual ADEE conferences were invited to attend focus groups to discuss aspects of feedback. Focus groups established an individual theme for the respective conferences: (i) the role of the teacher in delivering feedback; (ii) feedback from the students' perspective; (iii) changes to feedback due to the COVID-19 pandemic; and (iv) integrating feedback with assessments.

RESULTS

Qualitative data collected from the conference delegates were diverse and thought provoking. Delegates reported different styles of feedback varying from individual, personal feedback to no feedback at all. An enforced and mostly positive adaptation to online delivery during the COVID-19 pandemic was reported. A partial return to pre-pandemic practices was described.

CONCLUSIONS

Feedback is well recognized by students and teachers as contributing to learning. A universal approach to delivering feedback as part of the student learning process can be challenging due to a multitude of variables. Many aspects of changes in dental education, teaching, and feedback practices adopted as a result of the COVID-19 pandemic have been retained post-pandemic, thereby accelerating the anticipated progression to online teaching.

Entrustable professional activities in dental education: a scoping review

Background Competency-based education has led to the introduction of entrustable professional activities (EPAs) in health sciences education. EPAs are assessment tools that serve to certify a trainee's preparedness to conduct a given clinical activity. Objective Given its modest introduction into dental education, we sought to examine the current situation of EPAs in our field and identify possible barriers and facilitators. This review aimed to summarise evidence about EPA introduction in dental education programmes.Data sources A review of articles published between January 2005 and December 2021 was conducted using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews methodology in three databases (PubMed, Cochrane and Embase).Data selection Keywords were 'entrustable professional activity' OR 'entrustable professional activities' AND 'dentistry' OR 'dental education'.Data extraction Eligibility criteria targeted papers published in English describing dental education EPA.Data synthesis Ten publications were selected: six reported on new EPAs, three discussed their relevance for dental education and one article described a process for developing validated EPAs. EPAs focused on clinical examination, health promotion, treatment planning, pain and/or anxiety control and topics related to a specific discipline or care procedures.Conclusion Topics covered by EPAs described in our study adequately reflect the specificities of today's dental professional. The benefits of EPAs will ensure tomorrow's dentists consistently meet societal expectations.

A novel scale to measure students' perceptions of exemplars in a dental school

INTRODUCTION

Exemplars are an effective strategy for initial cognitive and psychomotor skill acquisition and promoting students' self-regulation. Yet, there is limited evidence about students' use and perception of exemplars in dental education. Therefore, this study aimed to develop a scale to measure students' perception of exemplars in an Australian dental school.

MATERIALS AND METHODS

Phase I assessed the relevant literature and students' responses to an interview. Four themes were identified for developing a 19-item questionnaire rated by an expert panel. Phase II piloted the questionnaire amongst a group of 30 students. Phase III analysed psychometric and qualitative open-ended questions data obtained from a large group of students.

RESULTS

The principal axis factoring resulted in one single factor that explained over 62% of the variance and had an alpha of .88. The number of questions was reduced from 19 to 6 items with loadings of 0.72 or above for each item. Students reported exemplars are beneficial for their learning and to visually guide them to understand procedures and their intended outcomes. This prompts them to think and mentally prepare before performing. Students further reported using exemplars provided by their courses almost as often as exemplars they search in social media.

CONCLUSION

Well-developed exemplars could play a key role in enhancing learning and could assist teaching. Understanding students' use and perception of exemplars will help educators to develop and evaluate appealing exemplars. Therefore, this study developed a new instrument to measure students' perception of exemplars, verified its reliability and validity.

Students' perception on flipped classroom with formative assessment: A focus group study

OBJECTIVE

To explore students' perception on the implementation of flipped classroom (FC) combined with formative assessment during the undergraduate teaching of orthodontic wire-bending skills.

METHODS

Third-year undergraduate dental students were taught wire-bending skills via FC teaching method using a series of pre-recorded online video demonstrations. As part of the formative assessment, the students were given the results and assessment rubrics of their prior wire-bending assessment before every subsequent session. Purposive sampling method for focus group discussion was used to recruit eight students comprising four high achievers and four low achievers. Strengths, weaknesses and suggestions for improvement of the FC with formative assessment were explored. Data were transcribed and thematically analysed.

RESULTS

Students perceived that FC allowed for a more convenient and flexible learning experience with personalised learning and improved in-class teaching efficiency. The pre-recorded online videos were useful to aid in teaching wire-bending skills but lacked three-dimensional representation of the wire-bending process. Students suggested better standardisation of instructions and access to the marking rubric before and after assessment.

CONCLUSIONS

FC teaching with continuous formative assessment and constructive feedback as a form of personalised learning was viewed favourably by students. The implementation of periodic individual feedback can further enhance their learning experience.

Teachers’ Feedback Practices in COVID-19: Has Anything Changed?

Objectives

Feedback delivered by teachers to dental students has a profound impact on students’ ongoing learning and development. The aim of this study was to investigate changes to feedback practices as a result of the global COVID-19 pandemic and the ensuing challenges to delivering quality dental education.

Methods

This was a mixed method study. Quantitative data were collected through a bespoke questionnaire delivered to attendees of the Association for Dental Education in Europe (ADEE) annual conference. Qualitative data were collected via four focus groups at the conference, each discussing a particular theme. The questionnaire and conference were delivered online via Gmail and MS Teams, respectively.

Quantitative data were analysed descriptively; qualitative data were analysed narratively, and both were triangulated.

Results

67 questionnaire responses were received which represented a 26% response rate. Respondents came from 12 different countries within Europe and beyond and reported having a variety of roles in their dental schools. 77.6% (n = 52) respondents indicated they had changed their delivery of feedback due to the pandemic. One-third of respondents reported giving more feedback and 76% (n = 51) increased their quantity of feedback delivered online.

The increased incidence of online learning had resulted in a greater emphasis on teaching small groups, increased use of technology, increased emphasis on student centred learning and heightened awareness of changing the style of feedback delivery.

Conclusions

The COVID-19 pandemic has enforced rapid changes to the delivery of feedback by teachers to dental students, which could pave the way for a more positive, inclusive, individualistic and effective approach for delivering feedback now and in the future.

Clinical significance

The COVID-19 pandemic resulted in a significant shift from face-to-face teaching to online tuition, which promoted a need to re-evaluate the best method of delivering feedback to students. The ongoing changes in teaching approaches have a profound impact on clinical skills acquisition for dental students. The quality of the feedback students receive may help to enhance the synergies between theoretical online teaching and hands-on clinical skills acquisition, which has been altered and disrupted due to the ongoing pandemic.

The relationship between feedback and evaluative judgement in undergraduate nursing and midwifery education: An integrative review

AIM

This integrative review aims to explore the relationship between feedback and evaluative judgement in undergraduate nursing and midwifery education.

BACKGROUND

Research in higher education has shown that feedback practices can lead to students' developing evaluative judgement; thought critical for performance improvement and life-long learning. While literature in nursing and midwifery education has not yet employed the term 'evaluative judgement' explicitly, there might be similar concepts and practices that seek to develop students' judgement of performance that sustain learning beyond the immediate task.

DESIGN

An integrative review of the nursing and midwifery feedback literature.

METHODS

In February 2020, six online databases (CINAHL, ProQuest, Scopus, ERIC, PsycINFO, Ovid MEDLINE) were systematically searched for literature published between January 1989-February 2020. Synonyms for feedback and evaluative judgement were used to inform our search. This review included a rigorous team-based, five-stage approach: (1) identifying the problem; (2) conducting the search; (3) evaluating the data; (4) analysing the data; and (5) presenting the integrative review.

RESULTS

A total of 1408 studies were initially retrieved with 543 duplicates. 865 abstracts were screened using eligibility criteria, resulting in the exclusion of 835 studies. Thirty full-text studies were appraised for quality. Eighteen studies with diverse methodologies achieved a medium-high quality score for inclusion in data analysis. Conceptions of feedback and evaluative judgement were identified in all studies; despite none using the term 'evaluative judgement' explicitly. Thematic analysis of the studies resulted in seven themes: conceptions of feedback, purposes of feedback, sources of feedback, modes of feedback, conceptions of evaluative judgement, purposes of evaluative judgement and relationships between feedback and evaluative judgement.

CONCLUSIONS

While our findings supported contemporary higher education research, the feedback-evaluative judgement relationship is novel in nursing education. We encourage educators to design feedback activities privileging students' active engagement through dialogic feedback, reflection and self-assessment, to develop their evaluative judgement of practice.

Longitudinal Curricular Assessment of Knowledge and Awareness of Intimate Partner Violence among First-Year Dental Students

Background: Intimate partner violence (IPV) has previously been recognized as a major public health issue. Oral healthcare providers, such as dentists, are crucial to the screening and identifying of individuals experiencing IPV, since most injuries occur in the head and neck region. A lack of knowledge and awareness regarding teaching and learning about IPV in dental school curricula has been identified. Based upon the overall lack of knowledge, the objective of this study was to conduct a longitudinal assessment of knowledge, awareness, and beliefs regarding IPV among dental students in their first year of education. Methods: All students (n = 245) from three consecutive, first-year dental student cohorts (n = 81, n = 82, n = 82) were provided a brief and voluntary in-class survey in conjunction with an instructional workshop. The survey included questions designed to ascertain knowledge, awareness, and beliefs regarding IPV as a healthcare and dental issue before and after the instructional session. Differences in responses to the questions before and after the IPV educational workshop were measured using paired t-tests. Results: A total of n = 232 completed pre- and post-responses were received from all three first-year dental student cohorts (n = 76, n = 80, n = 76), representing an overall 94.6% response rate. Analysis of these data showed that the student population was predominantly male and white (non-minority), aged in their mid- to late twenties, with most students reporting no previous IPV education. The few students reporting previous IPV education were mainly younger (<25 years), which may represent more recent endeavors to increase awareness of IPV among students currently attending colleges and universities. Conclusions: The results of this study may suggest that information-specific seminars within the curriculum might be adequate to provide dental students with awareness and knowledge of IPV and specific information regarding local resources and referrals for any patients experiencing IPV.

Feedback for Learning in Pharmacy Education: A Scoping Review

Feedback is an effective pedagogy aimed to create cognitive dissonance and reinforce learning as a key component of clinical training programs. Pharmacy learners receive constant feedback. However, there is limited understanding of how feedback is utilized in pharmacy education. This scoping review sought to summarize the breadth and depth of the use of feedback within pharmacy education and identify areas for future research. PubMed, Embase, Scopus, and Web of Science were searched for English articles since January 2000 to identify studies related to feedback in pharmacy education. Sixty-four articles were included for analysis, stratified by moderate and major theory talk, where moderate theory talk explicitly included feedback into study design and major theory talk included feedback into both study design and analysis. Feedback was provided in Bachelor (14%), Master (15.6%), Doctor of Pharmacy (67.2%) and post-graduate programs (4.7%) on a variety of curricular objectives including communication and patient work up in didactic, objective structured clinical examination (OSCE), and experiential settings, and career/interview preparation in the co-curriculum. Feedback comments were mostly written in didactic courses, and both written and verbal in OSCE, experiential, and co-curricular settings. The pharmacy education feedback literature lacks depth beyond student perceptions, especially with respect to assessing the effectiveness and quality of feedback for learning. While feedback has been utilized throughout pharmacy education across myriad outcomes, several areas for inquiry exist which can inform the design of faculty and preceptor development programs, ensuring provision of effective, quality feedback to pharmacy learners.
