The present study aimed to evaluate the perceptions of current or previous preclinical students at the College of Medicine, Najran University (NU) about the effectiveness of PBL and TBL and to assess ...
A cross-sectional survey was conducted on 106 preclinical students at NU, Saudi Arabia. The survey questionnaire was validated by a pilot study and designed based on Kirkpatrick's evaluation model. De...
73.6% of participants enjoyed PBL and found it motivating compared to TBL and classic lectures. PBL was reported as more effective for knowledge acquisition (50%), teamwork (62.3%), and high academic ...
It is concluded that PBL was more favored by the students regarding the learning outcomes. TBL was reported to need more individual preparation and effort and require lecturer involvement, suggesting ...
To enhance tutors' teaching skills, tutor shadowing for novice tutors of problem-based learning (PBL) in addition to conventional faculty development (FD) was applied. This study aimed to develop a tu...
This study employed a before-and-after study design with three phases. In phase 1, a TS-scale was elaborated. A validity examination was performed in phase 2. Phase 3 was a study of the effectiveness ...
A TS-scale with a 32-item questionnaire of self-rated confidence for PBL tutors was identified in phase 1. In phase 2, 7 experienced specialists in medical education were invited to evaluate the conte...
Novice PBL tutors benefit from FD that incorporates tutor shadowing in the 3 key domains of tutoring competencies. The TS-scale developed in this study can be applied in future research on FD design....
Problem-based learning (PBL) is a learner-centered method in which complex real-world problems are used to stimulate students thinking and problem-solving abilities during the teaching and learning pr...
This study developed a problem-based learning (PBL) module to improve integrated thinking and problem-solving ability in students of dental hygiene. After applying PBL, the study tested the improvemen...
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....
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 S...
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...
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, fur...
To study the application of PBL combined with CBL teaching mode in the teaching of international classification of diseases (ICD) encoding, so as to improve students' grasp of ICD encoding knowledge. ...
With traditional lecture-based learning methods often criticized for their limited ability to foster critical thinking and cognitive engagement, problem-based learning (PBL) has emerged as a promising...
PBL was implemented in an undergraduate public health course at a private university in the southeast US. The study was conducted in the Spring of 2022 using a convergent mixed-methods approach. Quant...
Results indicated significant improvements in student communication skills, growth mindset, and metacognitive abilities across the semester. The thematic analysis of qualitative responses corroborated...
The findings contribute to the growing body of evidence supporting PBL and offer practical insights for implementing PBL in public health education. The study also highlights the need for institutiona...
Problem-based learning (PBL) is a pedagogy involving self-directed learning in small groups around case problems. Group function is important to PBL outcomes, but there is currently poor scaffolding a...
Tool development unfolded in four steps: 1) a literature review was conducted to identify existent evaluation tools for group function in PBL, 2) literature findings informed the development of this n...
Nineteen scales relating to group function assessment were identified in the literature, lending 18 constructs that mapped into four dimensions: Learning Climate, Facilitation and Process, Engagement ...
A four-dimension tool to assist group function reflection in PBL was produced. Its constructs were well supported by literature and experts. Faculty and student stakeholders acknowledged the utility o...
