Does problem-based learning facilitate enactment of learner agency in undergraduate dental curricula? A Q study.

INTRODUCTION: Addressing a literature gap on leaner agency in health profession education, this study explores students' perceptions on which aspects of a problem-based learning (PBL) environment cradle their leaner agency enactment. METHODS: Thirty-eight students from a newly established undergraduate dental medicine programme in Qatar participated in the study. Q methodology was adopted to collect and analyse data both qualitatively and quantitatively. A 40-statement Q-set was established based on a proposed conceptual framework of learner agency in PBL, including three dimensions-intrapersonal, behavioural and environmental. RESULTS: Q methodological factor analysis identified four significantly different student viewpoints, which underscored participants' enactment of learner agency addressing the intrapersonal, behavioural and environmental dimensions of the conceptual framework. Despite differences in opinion regarding sources of learner agency, the four student viewpoints unanimously underscore the importance of PBL facilitators' expertise to nurture and develop agency amongst undergraduate students. Post-sorting qualitative data further confirmed the quantitative analysis. Time constraints and workload were identified as the main challenges by the participants. CONCLUSIONS: This study explored enactment of learner agency as perceived by undergraduate dental students in a PBL curriculum. The findings of this study provide new insights into participants' subjective understanding of learner agency in a PBL curriculum in dentistry. Structured support is needed for students having no prior PBL experiences to develop their learner agency at both intrapersonal and behavioural (self-regulated learning) dimensions, and to ensure they interact with their learning environment proactively.

Development of self-regulation amongst dental students in problem-based learning curricula: A qualitative study.

AIMS: To explore the value of problem-based learning in the development of self-regulation amongst undergraduate dental students. MATERIALS AND METHODS: A qualitative approach using focus groups was used to explore the perceptions and experiences of the participants regarding the role of problem-based learning (PBL) in promoting self-regulation in undergraduate dental education. The study was carried out at a newly established dental institution in Qatar. Purposive sampling technique was used to recruit the participants. Invitations to potential participants were sent by e-mail through appropriate professional channels. All focus groups were transcribed verbatim, and data were imported into NVivo 12 and analysed thematically. RESULTS: A total of five focus groups were conducted with 37 participants which included 27 females and seven males from two different cohorts. Participants expressed their views on a range of issues related to the self-regulation in problem-based learning and also provided recommendations to enhance the learning experiences of students. PBL was perceived to be an appropriate and effective strategy to support student autonomy in construction of knowledge and developing problem-solving and interpersonal skills. However, the workload of the students can impact adversely on their motivation and time management skills. CONCLUSIONS: This study provides useful insights into the concept of self-regulation in problem-based learning environments as perceived by the stakeholders at a newly established dental institution. The findings of this study may offer clarity on how problem-based learning can be best utilised to promote self-regulation in undergraduate dental education.

Health educators' professional agency in negotiating their problem-based learning (PBL) facilitator roles: Q study.

BACKGROUND: University educators are expected to cope with emerging situations and complex issues in teaching and learning, and this requires them to be agentic and proactive. While professional agency of health educators has not been investigated adequately, this study explores health educators' perception of their enactment of professional agency in the PBL facilitation process in a postpandemic context. METHODS: Forty PBL facilitators from medical and dental programs in Qatar University participated in the study during the fall semester of 2021, after resuming in-person PBL sessions. To collect and analyse data both qualitatively and quantitatively, Q methodology was employed. A 33-statement Q-set was established based on a proposed theoretical framework of professional agency in PBL facilitation, which included three dimensions-intrapersonal, action, and environment. RESULTS: Q factor analysis identified five significantly different viewpoints regarding how PBL facilitators perceive their professional agency sources, namely, (1) institutional resources, (2) policy guideline, (3) making efforts to improve support for students, (4) beliefs on PBL effectiveness, and (5) agentic actions. While four of the viewpoints were positive, participants with the second viewpoint reported negative perceptions and described lack of interest in facilitation work. All three dimensions of the framework were addressed and indicated complexity and interrelatedness of agency enactment. Consensus was observed regarding the need for more professional learning activities for faculty involved in PBL facilitation as source of professional agency. DISCUSSION: The results revealed a high variation of participants' perceptions of professional agency enactment throughout the three dimensions, indicating the need for establishing a common understanding of PBL facilitation work in a given context. For practical implications, further institutional efforts are required to support professional learning for PBL facilitation in a postpandemic context. Alternate approaches highlighting enforcement of agentic actions in all dimensions of intrapersonal values, stance and action taking, and active interactions with students, colleagues, and institutional environments are crucial. Q methodology provides new conceptual and empirical insights to explore the subjectivity of actors in health education.

A qualitative enquiry into dental students' perceptions of dentistry as a career choice in the State of Qatar.

BACKGROUND: Career choice is a complex, multifaceted process affecting all aspects of life. Motivational factors of aspiring dentists are crucial to inform institutions and aid with the admission process. The aim of this study was to explore undergraduate dental students' perceived motivation for their career choice in the first dental institution in the State of Qatar to bridge the gap in knowledge in this area. METHODS: Homogeneous purposive sampling technique was employed to collect data from all year 2 and year 3 undergraduate dental students to gain a deeper insight into their motivation of career choice. An explorative qualitative method using face-to-face focus group sessions were utilized. All focus groups were conducted in English and contained a moderator and observer. A topic guide was used to ensure data collection standardization. Participants' views were recorded and filed notes obtained. Data was transcribed and analysis performed utilizing an inductive thematic approach. RESULTS: A total of 34 students (89.5%) from year 2 and 3 participated in the focus groups. Data analysis revealed six main themes emerging from this study namely; altruism and patient care, family influence factors, childhood aspirations, hands-on practical skills, professional and social status, and the opportunity to reconsider and transfer. Based on frequency, altruism, opportunities to learn hands-on practical skills and professional status appeared to be the main drivers influencing students' choice of dentistry as a professional career. CONCLUSION: This qualitative study presents the first national study providing insightful information regarding current undergraduate dental students' decision process in relation to their profession selection, and shows that opportunities to provide patient care seems to be the key to motivation. There was also a strong inclination towards performing hands-on practical tasks as a dentist, and developing a professional status. Interestingly, financial reward did not feature as a motivational factor in this study. The study highlights the influence of socio-cultural and economic factors on choosing dentistry as a career. This data could help dental institutions better understand future applicant's motivations to join dentistry and assist with the academic recruitment/admission process and targeting students with a potential to excel in the profession.

Development of professional identity among dental students - A qualitative study.

PURPOSE: The study explored dental students' perception of their professional identity (PI) development at a newly established dental college with a problem-based learning (PBL) curriculum. METHODS: Qualitative methods based on focus groups were used for data collection. The conceptual framework of the study was informed by a subject-centered sociocultural approach to PI development. Purposive sampling was used to collect data from five focus groups of undergraduate dental students to gain a deeper understanding of their PI development in a PBL environment. RESULTS: Out of a total of 38 dental students in years 2 and 3, 34 students (89.47%) participated in the focus groups. A theory-driven thematic analysis was used to dissect the views and experiences of the participants to explore factors contributing to PI development in the early years of the program. At an individual level, PBL was seen to be appropriate for PI development. However, some participants placed more emphasis on practical training in operative dental skills. Relational sources especially role modeling by the PBL facilitators and faculty staff were identified as a key factor to nurture PI development. Mixed views were observed on the value of PBL to enhance team-working skills. The participants also identified challenges of PBL and provided recommendations on further improvements to enhance the learning experiences of the students. CONCLUSIONS: This study provided useful insights into a PBL curriculum at a newly established dental institution. The findings underscore the value of PBL in developing PI and also highlight the challenges of implementing PBL in a socio-cultural context and pedagogical implications for further program improvement.

Microfluidic spinning-induced heterotypic bead-on-string fibers for dual-cargo release and wound healing.

The preparation of dual-release pharmaceutical microfibers provides an ideal material for new biomedical applications. We describe a microfluidic spinning method for engineering heterotypic bead-on-string fibers with the ability to carry dual cargos and to deliver on demand. The core of our technology is to combine microfluidic spinning with biomaterial preparation, in which hydrophobic and hydrophilic cargos can be integrated into a bead-on-string microfiber structure. We demonstrate the loading of bovine serum albumin (BSA) in the sodium alginate phase and ibuprofen in the polylactic acid (PLA) phase, respectively. The heterotypic bead-on-string fibers are biocompatible and show hemostatic ability in vivo. These heterotypic bead-on-string fibers are then woven as a skin scaffold and shown to promote wound healing by loading antibacterial and anti-inflammatory cargos.
