Presents an instrumental analysis laboratory section of a problem-based format that includes elements of authentic, investigative, and cooperative learning. Discusses students' attitudes, achievement, and effects of the problem-based instruction on the learning process and higher order thinking in laboratory students. (KHR)

Highlights the differences between classical teaching methods and problem-based learning. Describes the curriculum and problem-based approach of the Faculty of Medicine at the Maastricht University and gives an overview of the implementation of biochemistry in the medical curriculum. Discusses the procedure for student assessment and presents…

Focuses on the implementation and evaluation of instructional strategies in a core science education methods course within a Bachelor of Education preservice program. Examines how a collaborative learning experience that incorporated components of problem based learning was implemented and how students reacted to and reflected upon this approach.…

This article tells the story of the design of Learning by Design(tm) (LBD), a project-based inquiry approach to science learning with roots in case-based reasoning and problem-based learning, pointing out the theoretical contributions of both, classroom issues that arose upon piloting a first attempt, ways we addressed those challenges, lessons…

In traditional science teaching, teachers expect the average student to implicitly learn and apply subtle concepts and to connect seemingly disjointed information. Teachers expect them to actively assemble the building blocks of critical thinking, often without example (Meyers 1986). The critical analysis of issues and problems is second nature to…

A protein lacking one of the 20 common amino acids is a protein lipogram. This open-ended problem-based learning assignment deals with the evolution of proteins with biased amino acid composition. It has students query protein and metabolic databases to test the hypothesis that natural selection has reduced the frequency of each amino acid…

Presents: (1) a list of ideas for teaching problem-solving; (2) a review of a problem-solving book used in medical education; and (3) a discussion of an approach called problem-based learning. (DH)

Education has traditionally studied the world by bringing it into the classroom. This method can result in situated learning that appears to students to have no relevance outside the classroom. Students acquire inert, decontextualized knowledge that they cannot apply to real problems. The obvious solution to this shortcoming is to reverse the…

Describes a sea-water analysis project that introduces qualitative and quantitative analysis methods and laboratory methods such as gravimetric analysis, potentiometric titration, ion-selective electrodes, and the use of calibration curves. Uses a problem-based cooperative teaching approach. (Contains 24 references.) (YDS)

Argues that problem-based learning (PBL) shows students that the best scientists are not those who memorize facts, but rather those who apply facts in a creative manner. Explains that the author, who incorporated group learning into a general education science course, found that PBL led to increased class attendance and participation. (Contains…

Outlines a plan of action designed to enhance growth in problem-posing skills. The "blueprint" provides a model for teachers and teacher educators who wish to integrate more problem posing into their curriculum. Specific activities and instructional strategies are cited to illustrate the development of problem posing as a process in the classroom.…

Details a study exploring a problem-based learning framework used to develop preservice teachers' knowledge base for teaching and pedagogical reasoning ability. Emphasizes an undergraduate preservice science teacher education unit. Contains 30 references. (DDR)

Explores the effects of a Problem-based Computer-Assisted Instruction (PBCAI) on students' earth science achievement in Taiwan. One hundred and fifty-nine 10th grade students enrolled in four sections of a mandatory earth science course participated in this pretest- posttest control group experiment. A significant difference was found between the…

The aim of this study was to compare the achievement of prospective primary science teachers in a problem-based curriculum with those in a conventional primary science teacher preparation program with regard to success in learning about gases and developing positive attitudes towards chemistry. The subjects of the study were 101 first year…

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…
