The FGF receptor Heartless (HTL) is required for mesodermal cell migration in the Drosophila gastrula. We show that mesoderm cells undergo different phases of specific cell shape changes during mesoderm migration. During the migratory phase, the cells adhere to the basal surface of the ectoderm and exhibit extensive protrusive activity. HTL is required for the protrusive activity of the mesoder...

Problem based learning (PBL) is an approach to professional education that has been adopted in higher education in various countries. But in India, PBL is still not included in the curriculum in many medical schools. Our aim is to study the changing pattern of learning approaches to pharmacology adopting PBL by undergraduate students of an Indian medical school. Medical students(n= 143) at Mela...

PURPOSE Problem-based learning (PBL) is usually conducted in small-group learning sessions with approximately eight students per facilitator. In this study, we implemented a modified version of PBL involving collaborative groups in an undergraduate chiropractic program and assessed its pedagogical effectiveness. METHODS This study was conducted at the International Medical University, Kuala L...

CONTEXT The University of Hawai'i Pacific Basin Bioterrorism Curriculum Development Project has developed a problem-based learning (PBL) curriculum for teaching health professionals and health professional students about bioterrorism and other public health emergencies. These PBL cases have been incorporated into interdisciplinary training settings in community-based settings, such as in the sm...

Existing Problem-Based Learning (PBL) problems, though suitable in their own right for teaching purposes, are limited in their potential to evolve by themselves and to create new knowledge. Presently, they are based on textbook examples of past cases and/or cases that have been transcribed by a clinician. In this paper, we present (a) a tacit healthcare knowledge representation formalism called...

The past decade has seen increasing demands for reform of dental education that would produce a graduate better equipped to work in the rapidly changing world of the twenty-first century. Among the most notable curriculum changes implemented in dental schools is a move toward Problem-Based Learning (PBL). PBL, in some form, has been a feature of medical education for several decades, but has on...

Problem-based learning (PBL) can be described as a learning environment where the problem drives the learning. This technique usually involves learning in small groups, which are supervised by tutors. It is becoming evident that PBL in a small-group setting has a robust positive effect on student learning and skills, including better problem-solving skills and an increase in overall motivation....

The definition of problem-based learning (PBL) as an educational concept is as elusive in 2008 as it has been since the concept was first expressed over forty years ago. A definitive guide to the practice of PBL is equally elusive. Like all worthwhile educational ideas, PBL has proved attractive to those teachers who seek improvements for their courses. Its appeal has transcended the traditiona...

Many important changes have taken place in the educational models used at universities outside the People’s Republic of China (PRC) over the last few decades. Innovative teaching methods, such as PBL provide new and interesting models of teaching aimed at improving student learning. One of the most important aspects of PBL is the role of students in the learning process as PBL places the studen...

BACKGROUND Problem-based learning (PBL) and interprofessional education (IPE) are becoming increasingly well-established concepts in modern undergraduate medical school curricula. The delivery of IPE through a PBL setting appears to hold good face validity. However, there has to date been no published review of the evidence for the value of combining these two teaching methods. METHODS A revi...
