This study examined the effect of scaffolding learning components in a computerized environment, for students solving qualitative science problems in a simulation of laboratory experiments. Four scaffolding components were identified (structural, reflective, subject-matter and enrichment) and used in different configurations to construct four…

The significant increase of English Language Learners (ELLs) in the United States raises complex questions about how to provide these students with access to high quality education that can improve both their content knowledge of school subjects and their English proficiency, particularly their academic English proficiency. The development of…

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…

Understanding the nature of science is even more important than mastering its details, says Alan Leshner, Chief Executive Officer of the American Association for the Advancement of Science, in an interview with Educational Leadership. In this article, Leshner discusses the controversy about teaching evolution, and he asserts that demands to…

An action research study investigated how the multiple tasks found in WebQuests facilitate fifth-grade students' literacy skills and higher order thinking. Findings indicate that WebQuests are most successful when activities are carefully selected and systematically delivered. Implications for teaching include the necessity for adequate planning,…

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…

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…
