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.

Temporomandibular disorder symptoms and their association with quality of life of dental patients in Malaysia.

OBJECTIVE: To assess the prevalence of temporomandibular disorders (TMD) and their effects on quality of life (QoL) of dental patients. METHODS: A survey consisting of two validated questionnaires was distributed to dental patients registered at the University of Malaya Faculty of Dentistry. The Fonseca Anamnestic Index (FAI) evaluates the prevalence and severity of TMD, while the Oral Health Impact Profile - Temporomandibular Disorder (OHIP-TMD) appraises the effects of TMD on oral health-related QoL. RESULTS: Out of 342 patients (aged 16 to 50 years, 45% male and 55% female) enrolled in the survey, 50.9% had varying degrees of TMD. All 7 domains of OHIP-TMD showed a statistically significant correlation with TMD severity. CONCLUSION: TMD seems to be prevalent among Malaysian dental patients. Not only does TMD affect the QoL of an individual, but the more severe the degree of reported symptoms, the poorer their perceived oral health QoL.

Dental Aesthetics and Self-Esteem of Patients Seeking Orthodontic Treatment.

(1) Objective: This study aimed to investigate how patients' perceptions of their dental aesthetics and their sense of self-esteem are related. (2) Methods: This cross-sectional survey recruited 141 new patients seeking orthodontic treatment. Patients completed a self-administered questionnaire consisting of three parts: the Malaysian Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), Rosenberg Self-esteem Scale (RSES-M), and Aesthetics Component of the Index of Orthodontics Treatment Need (IOTN-AC). Clinical assessment comprised the Dental Health Component of the Index of Orthodontics Treatment Need (IOTN-DHC). Multiple linear regression was performed, with self-esteem as the dependent variable, while the independent variables comprised the domains of PIDAQ; IOTN-AC; IOTN-DHC; and patients' demographics, such as age, gender, and their level of education. (3) Results: The response rate was 96.5% (n = 136 respondents). The multiple linear regression found that, when the other predictors in the model are held constant, Social Impact, Aesthetic Concern, and Dental Self-Confidence are the factors that significantly contributed to explaining the variation in self-esteem, accounting for, 3.9%, 2.3%, and 2.0%, respectively. The entire model explained 23% of the variation in self-esteem. (4) Conclusions: Domains of the psychosocial impact of dental aesthetics act as predictors of self-esteem in orthodontic treatment-seeking patients.

Students' perception on flipped classroom in contrast to live demonstration for teaching orthodontic wire-bending skills: A focus group study.

OBJECTIVE: This study aimed to explore students' perceptions of flipped classroom (FC) compared to live demonstration (LD) in transferring skills of fabricating orthodontic wire components for orthodontic removable appliances. METHODS: Forty third-year undergraduate dental students were randomly assigned to two groups: FC (n = 20) and LD (n = 20). Students in group FC attended FC, while students in group LD attended LD. Both groups underwent a series of standardized teaching sessions to acquire skills in fabricating six types of orthodontic wire components. Eight students (four high achievers and four low achievers) from each group were randomly selected to attend separate focus group discussion (FGD) sessions. Students' perceptions on the strengths, weaknesses, and suggestions for improvement on each teaching method were explored. Audio and video recordings of FGD were transcribed and thematically analyzed using NVivo version 12 software. RESULTS: Promoting personalized learning, improvement in teaching efficacy, inaccuracy of three-dimensional demonstration from online video, and lack of standardization among instructors and video demonstration were among the themes identified. Similarly, lack of standardization among instructors was one of the themes identified for LD, in addition to other themes such as enabling immediate clarification and vantage point affected by seating arrangement and class size. CONCLUSIONS: In conclusion, FC outperformed LD in fostering personalized learning and improving the efficacy of physical class time. LD was more advantageous than FC in allowing immediate question and answer. However, seating arrangement and class size affected LD in contrast to FC.

Comparing flipped classroom and conventional live demonstration for teaching orthodontic wire-bending skill.

Flipped classroom may overcome weaknesses of live demonstration in teaching orthodontic wire-bending. This study aims to compare the effectiveness between flipped classroom and live demonstration in transferring skills for fabricating Adams clasp. Forty third-year undergraduate dental students were assigned to two groups. The students in group LD (n = 20) attended a live demonstration while students in group FC (n = 20) attended a flipped classroom. Both groups were taught on skills to fabricate Adams clasp in a standardised way. Each student from both groups were asked to submit an Adams clasp for a blinded quality assessment by two trained and calibrated assessors using a 18-item rubric, followed by validated students' satisfaction questionnaires to evaluate their perceived satisfaction on the teaching method received. A crossover study was then conducted three weeks later where LD attended a flipped classroom while FC attended a live demonstration. Students' satisfaction questionnaires were again collected from each student for blinded analysis. Mean scores for the quality of Adams clasp were 9.775 and 9.125 for LD and FC, respectively. No significant difference was detected between the two groups. Statistically significant association was found for one statement on the questionnaire, "I found the classroom arrangements conducive for the wire-bending activity" (p = 0.010). No significant differences were found between the two groups for other statements (p > 0.05). In conclusion, within the limitations of the study, flipped classroom is equally effective as conventional live demonstration in transferring orthodontic wire-bending skills for fabrication of Adams clasp. However, students perceived the classroom arrangements during the flipped classroom significantly more conducive for teaching orthodontic wire-bending.
