The aim of this study was to investigate the effectiveness of a problem-based learning (PBL) approach in a physical chemistry laboratory course. The parameters investigated were students' attitudes towards a chemistry laboratory course, scientific process skills of students and their academic achievement. The design of the study was one group…

A weak negative attitude towards learning science was noticed among the students in Qatar, a matter that was reflected on their achievement in national tests. To test if the use of PBL would improve the students' attitudes towards learning science, a sample of 25 nine graders from Hamza school were motivated to plan their own investigations and to…

Reflection involves active, persistent, and careful consideration of any belief or practice. It promotes understanding of underlying beliefs and application of new knowledge to new situations. Problem-Based Learning (PBL) provides the instructional mechanisms for prompting learner reflective thinking. Research questions for this study were: (1)…

In response to HE 528 462, the author suggests the use of student-generated learning issues in problem-based medical education should place more emphasis on mechanisms in the generation of learning issues, the ramifications of various degrees of student input into the identification of issues, and the role of teacher-learner negotiations in the…

In this paper a multimedia project was incorporated into a problem-based learning environment to examine how learning in multimedia could be enhanced through the use of problem-based learning. Students in a second year course in the Faculty of Creative Multimedia (FCM) were assigned the problem-based multimedia project, they worked in groups,…

This qualitative study explored health sciences students' perceptions of their experiences in online problem based learning (PBL) and focused on their views about learning and group process in the online environment. Participants were novices to online learning and highly experienced in PBL, therefore, they could reflect on past face-to-face PBL…

Introduction: In group learning settings like problem-based learning (PBL), the quality of interaction is closely related to group success. However, research and practice have shown that the interaction in tutorial groups is not optimal. In the present study, a questionnaire was used to measure students' perceptions of occurrence and desirability…

The purpose of this research study was to examine the effectiveness of problem-based learning (PBL) on eleventh grade students' understanding of "The effects of temperature, concentration and pressure on cell potential" and also their social skills. Stratified randomly selected control and experimental groups with 20 students each were used in…

This study investigated students' conceptions of constructivist learning activities in a problem-based learning (PBL) and a traditional curriculum. We examined whether students who have chosen for a problem-based curriculum have different conceptions of constructivist assumptions compared to students who have chosen to be enrolled in a…

Concept maps have been used successfully in science and mathematics education in a variety of settings. This paper describes the application of the metacognitive tool, concept mapping, to the development of an integrated veterinary curriculum, to the development of case-based exercises for problem-based learning, and as a learning tool for…

A study was initiated at the inception of the Exploring the Environment (ETE) project to look at critical factors concerning the use of problem-based learning in Earth science classes. During the 1995-96 school year, the Tropical Poison module from the ETE Project was evaluated in nine high schools across the country. The module introduced…

Describes a study that examined the potential of a hypermedia-based expert tool to scaffold regular education sixth graders engaged in a problem-based learning program. Topics include cognitive apprenticeship support for problem-based learning; using hypermedia to offer expert modeling; attitudes toward the learning environment; and self-directed…

Interviews with faculty in seven problem-based medical school curricula concerning use of student-generated learning issues found that uses of such issues have evolved in terms of content definition, direct examination planning, student evaluation, and curriculum review. Results also suggest these curricula may encourage development of…

Describes development and evaluation of eight computerized problem-based learning (PBL) cases in medicinal chemistry and pharmaceutics concepts. Case versions either incorporated concept maps emphasizing key ideas or did not. Student performance on quizzes did not differ between the different case versions and was similar to that of students who…

The purpose of this quasi-experimental study was (a) to determine if there was a difference in knowledge achievement by Thailand's vocational students instructed using constructivist instruction (with open-end dialogue, problem-based learning, and cooperative learning) and using traditional instruction (with lectures, directed demonstrations, and…
