Described is how an iconic model building software can be used to help students gain a deeper qualitative conceptual understanding of physics concepts. The program, STELLA, links research about misconceptions and new teaching strategies with the use of modern information technology tools. (31 references) (KR)

Some of the persistent misinformation offered to secondary students while studying chemistry is discussed. A few cases where plausibility, knowingly or otherwise, has been offered to students instead of the accurate explanation are described. Concepts of charge, current, the mole, amount, rates, activation energy, sign convention in voltaic cells,…

The role of analogical mapping in the formation of conceptual misrepresentations was studied by analyzing target-domain inferences generated by 193 third graders learning from an analogy. Explicit knowledge of the instructional goal decreased the number of conflicting inferences. Implications for learning are discussed. (SLD)

A common misconception among students setting up force-acceleration problems is to think of the expression "mass times acceleration" as a force itself. Presents a new formula to express the relationship between force, mass, and acceleration, and discusses its benefits. (MDH)

Describes thought-provoking activities with the Cartesian Diver system. Presents student answers explaining the phenomena. (PR)

Finds that students taught with a constructivist approach had much more increased personal knowledge concerning energy compared to students taught in a traditional manner. (Contains 15 references.) (Author/WRM)

This article describes the light-based science circus the authors developed and tested with a fifth-grade class at Blackwell Elementary School in Richmond, Virginia. A science circus is a set of activities done in any order that together illustrate complementary properties of a science topic. As in a traditional circus, several "performances"…

This study explored how some college students understand the nature of the theory of evolution and how they evaluate its scientific status. We conducted semistructured interviews with 15 college biology seniors in which we asked them to explain why they think evolution assumes the status of a scientific theory, how it compares to other scientific…

A proactive instructional strategy for teaching evolution, which consists of the use of small group and peer discussion, is presented. While teaching about evolution, the teachers should consider and address the needs of the students and see the practical implications of the evolutionary theory by overcoming apprehension, misunderstanding and…

Frictional force is a source of misconceptions among students, as teachers know from daily experience. This is confirmed by many studies carried out by investigators from all over the world. Surprisingly (or perhaps not), we have found some of these misconceptions among physics school teachers and senior students of physics education courses…

The field of early intervention has long been involved in a heated debate between proponents of behavioral teaching strategies and professionals against it. This debate has become more focused and clearly more relevant to the quality of services afforded to young children with special needs because more of these youngsters are being served in…

After spending most of the day in school, students are given additional assignments to be completed at home. It is worth asking not only whether there are good reasons to support the nearly universal practice of assigning homework, but why it is so often taken for granted--even by vast numbers of teachers and parents who are troubled by its impact…

Scholars have provided numerous critical analyses of the structural causes of poverty. Unfortunately, many teachers are still led to believe, via best selling books and mainstream discourse, that behaviors, neighborhoods, and families determine educational outcomes. This "culture of poverty" theory must be disproved; educators need to be…

There has been a broad wave of change in tertiary calculus courses in the past decade. However, the much-needed change in tertiary pre-calculus programmes--aimed at bridging the gap between high-school mathematics and tertiary mathematics--is happening at a far slower pace. Following a discussion on the nature of the gap and the objectives of a…

The purpose of this study was to report the results of a nationwide survey of Taiwanese high schools students' understandings about electric circuits. The study involved two stratified random samples consisting of 7,145 students in Grades 8 and 9, and 2,857 students in Grade 11, accounting for about 2.3% of the total enrolment in the corresponding…
