Method: The participants of this study (N=36) were registered for a bachelor's degree program in TCM in 2016 and enrolled in the Science of Acupuncture and Moxibustion course beginning in September 2018. The students were randomly allocated into two groups: PBL group and conventional group. A self-administered learning satisfaction survey and the Rosenberg Self-Esteem scores were used for data collection. An independent sample t-test was used to compare the results between the two groups. A p-value <0.05 was considered significant.
Results: The results of the learning satisfaction survey and Rosenberg Self-Esteem scores were significantly better in the PBL group than in the conventional group (p<0.05).
Conclusions: PBL appears to be more effective for clinical acupuncture education than the conventional teaching method. However, further studies are needed to identify the mechanisms by which PBL excels in clinical acupuncture education, as well as other related TCM fields.
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.
METHODS: All second-year undergraduate Bachelor of Dental Surgery (BDS) students were invited to participate in a TBL-CBL session. These participants were randomly allocated to six different groups of 10-12 students, and the session was conducted by one lecturer as the facilitator. A 23-item questionnaire assessing four domains (perceptions of effectiveness, teacher, team interaction and learning environment) was administered at the end of the TBL-CBL session.
RESULTS: The response rate was 91.9% (n = 68). Mean scores for the questionnaire items ranged from 4.13 to 4.60 suggesting a positive perception among the students towards the hybrid TBL-CBL approach. Regarding the open-response questions, students emphasised that the TBL-CBL session was effective for team interaction and group discussions. However, students wished to have a better venue for future sessions.
CONCLUSION: Positive perceptions of the students encourage future educators to consider the use of TBL-CBL approach in teaching dental materials science and to avoid the reliance on standalone conventional lectures. Future research could consider examining its effects on students' academic achievement as well as the perspectives of teachers regarding its adoption in different dental specialities.
