Dear Sir, I thank Dr. AlAmodi for his thought-provoking Eye Opener on the similarity between problem-based learning (PBL) and undergraduate research [1]. Overall, I agree with Dr. AlAmodi’s ‘small laboratory’ concept, and based on my own experience of a case-based learning (CBL) curriculum, I believe the concept extends beyond PBL to similar small-group inquiry-based teaching methods such as CB...

PURPOSE This study aimed to compare the effects of the problem-based learning (PBL) method with the traditional lecture method on learning in the cardiorespiratory nursing section of the Adult Health Nursing course. METHOD A pretest-posttest experimental design was used. A total of 71 second-year nursing students in a three-year nursing program in Korea participated: 35 students in the PBL gr...

Although, Problem Based Learning (PBL) has a strong theoretical supports from the literature, to date there has been many PBL research resulted with unexpected findings, leading to a conflict on the effect of PBL on students’ critical thinking ability. In this review, the authors investigated the theoretical relation, as well as reviewed the recent empirical evidence on the effect of PBL on stu...

PURPOSE The purpose of this study was to test a new problem-based learning (PBL) method to see if it reinvigorated the learning experience. METHOD A new PBL format called PBL 2.0, which met for 90 min two times per week, was introduced in 2009 into an 11-week integrated neuroscience course. One hundred second-year medical students, divided into 10 groups of 10, who had completed their first y...

We are developing a gene therapy method of HIV infection based on the constitutive low production of interferon (IFN) beta. Peripheral blood lymphocytes (PBL) from HIV-infected patients at different clinical stages of infection were efficiently transduced with the HMB-HbHuIFNbeta retroviral vector. The constitutive low production of IFN-beta in cultured PBL from HIV-infected patients resulted i...

Helping students in the professions apply conceptual ideas to the problems of practice is a key goal of problem-based learning (PBL). Because PBL is organized around small, collaborative groups, scaling up PBL to large, heterogeneous classes poses significant challenges for implementation. This study presents a hybrid model that mixes online and face-to-face PBL. The STELLAR system was develope...

Problem-based learning (PBL) is an instructional approach in which students learn problem-solving and teamwork skills by collaboratively solving complex real-world problems. Research shows that PBL improves student knowledge and retention, motivation, problem-solving skills, and the ability to skillfully apply knowledge in new and novel situations. One of the challenges faced by students accust...

BACKGROUND Medical schools have been making efforts to develop their own problem-based learning (PBL) approaches based on their educational conditions, human resources and existing curriculum structures. This study aimed to explore a new framework by integrating the essential features of PBL and coaching psychology applicable to the undergraduate medical education context. METHODS A participa...

Pigeon breeder's lung (PBL) is a type of lung inflammatory disease associated with the immune response to repeated pigeon-derived antigen exposure. The pathogenesis of PBL remains unclear. In this study, peripheral blood samples were collected from Uygur acute - and chronic-phase PBL patients and healthy subjects with pigeon contact. Foxp3+CD4+ regulatory T cell (Treg) activity in different pha...

The influence of problem-based learning (PBL) and open-book tests on long-term knowledge retention is unclear and subject of discussion. Hypotheses were that PBL as well as open-book tests positively affect long-term knowledge retention. Four progress test results of fifth and sixth-year medical students (n = 1,648) of three medical schools were analyzed. Two schools had PBL driven curricula, a...
