An integrated learning object, a web-based inquiry environment "Young Scientist" for basic school level is introduced by applying the semiosphere conception for explaining learning processes. The study focused on the development of students' (n=30) awareness of the affordances of learning objects (LO) during the 3 inquiry tasks, and their ability…

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…

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…

Many proven research-based instructional strategies have been developed for introductory college-level physics. Significant efforts to disseminate these strategies have focused on convincing individual instructors to give up their traditional practices in favor of particular research-based practices. Yet evidence suggests that the findings of…

"Lettuce Learn Math" is an interdisciplinary program that has effectively linked a small-scale agricultural production system to a sixth-grade mathematics and science curriculum. The mathematical concepts and skills, including measurement and geometry, taught in this project met and often exceeded the standards set by New York state for…

Undergraduate biology programs are currently undergoing reform to involve students in biomedical research. Engaging students in more active, hands-on experiments allows students to discover scientific principles for themselves, and to develop techniques of critical thinking and problem solving. This models the world of real scientific research,…

Many chemists want to be effective teachers but have little background in psychology or education on which to build successful practices. The primary audience for this book is chemistry teachers at the secondary and tertiary levels, and its purpose is to encourage readers to construct a new understanding of how their students learn. This book is…

The role of performance assessments in making cognitive activity apparent to teachers and students was studied through descriptions of the cognitive activity of 31 fifth-grade students. Differences while carrying out a science performance assessment reveal critical differences between those who think and reason well with their knowledge of…

In six parts, this research panel report focuses on numerous aspects of an institutionally-supported project in Writing and Problem Solving across Disciplines conducted by four teachers at Central Oregon Community College in Bend, Oregon. The report's first section, "Introduction," is descriptive and gives some background on the research…

This handbook offers teachers suggestions for ways to help students become risk-takers. Five levels of risk-taking behavior are identified: the uninhibited risk-taker, the analytical risk-taker, the cautious risk-taker, the inhibited risk-taker, and the nonrisk-taker. The importance of risk-taking for problem solving, and the teacher's role in…

Problems concerning conceptual change from existing knowledge (accumulated from everyday experiences or earlier teaching) to new scientific knowledge concerning natural phenomena are fundamentally the same for Western and non-Western students. However, difficulties experienced by non-Western students are magnified by factors such as their cultural…

A theoretical model specifying the underlying knowledge and procedures whereby human subjects can generate effective initial descriptions of scientific problems was formulated. The model is prescriptive since it does not necessarily try to simulate the behavior of actual experts nor assume that their performance is optimal. The model, elaborated…

Problem solving, both theoretical and practical, is the underlying skill developed through the physics curriculum. Service-learning has been integrated into engineering curricula, but programs proposed for that field often do not fit well into the structure of physics departments. A consultant-based approach to service-learning offers physics…

The categories and applications of strategic knowledge as these relate to problem solving in the area of transmission genetics are examined in this research study. The role of computer simulations in helping students acquire the strategic knowledge necessary to solve realistic transmission genetics problems was emphasized. The Genetics…
