This interpretive case study of a teacher aims to provide an account of the difficulties and rewards of putting innovative teaching into practice. Detailed descriptions of classroom life are used to explore one teacher's attempts to make technology-enhanced, open-ended inquiry a successful mode of teaching science in the secondary school…

This study employed problem-based learning for project work in a year 9 biology class. The purpose of the study was to investigate (a) students' inspirations for their self-generated problems and questions, (b) the kinds of questions that students asked individually and collaboratively, and (c) how students' questions guided them in knowledge…

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…

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…

This action research study evaluated problem-based learning (PBL), traditional lecture, and a combination of PBL and lecture in an elective biochemistry course at a secondary school for gifted students. Lecture tended to wide content coverage, whereas understanding and retention was promoted by PBL. (Author/DB)

Reports on the development of a series of assignments for use in a basic microbiology course involving sophomore-, junior-, and senior-level students from five different biology majors. Assignments include writing, a class debate, and case history studies. (Author/MM)

Briefly summarizes methods of presenting laboratory information. Suggests that approaching lab problems requires a combination of methods structured into a problem-oriented learning experience. Focuses on the relationship of the gloxysome to the chloroplast and the steps involved in solving the problem. (DDR)

An instructor contemplating a course transformation to incorporate a student-centered learning environment may feel faced with what seems like a high-wire balancing act--a constantly renegotiated compromise between students' legitimate needs for structure, well-understood expectations, and good grades and instructors' foreknowledge that the path…

The population of the United States continues to become increasingly diverse, both culturally and linguistically. The increased diversity creates a challenge for middle school teachers as they are required not only to teach their content areas, but also to assist students learning English, including literacy skills. The majority of teachers at all…

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…

The NASA "Why?" Files is a free annual instructional distance learning program that integrates science, mathematics, and technology. The program targets 3rd through 5th grade students and uses a problem-based teaching approach. This lesson guide includes four segments, each with objectives, vocabulary, video component resources, career ideas, and…

Presents an instructional framework for real-world, problem-based studies that can be used in a variety of settings. Discusses background knowledge, problem exposition, data collection and analysis, data synthesis and solution presentation, and career information. (JRH)

Reports on the views on problem-solving developed by prospective elementary teachers as a result of experiencing problem-centered learning in an integrated math-science methods course. Discusses four assertions related to students' attitudes toward problem-solving, their knowledge of problem-solving and problem-solving processes, and the role of…

A study used computer analysis to examine distribution of basic science content in the 53 cases in the problem-based medical curriculum of Rush Medical College (Illinois) and compared it to application of that content by students and faculty. The method of analysis is recommended for reviewing curricula for omissions and redundancy. (Author/MSE)
