Developing representational competence early in chemistry education is important. However, research to uncover students' difficulties with representational competence of basic chemical concepts in the early years of their chemistry course is scarce. The purpose of this study was to investigate and identify these difficulties. A total of 384…

"Limit" is a difficult mathematical concept, even for good students. It is also a key foundational idea for the study of advanced mathematics. It holds a central position as a foundation of the theory of approximation, of continuity, and of differential and integral calculus. However, the difficulty for teachers is how to organise…

The study involved evaluating the efficacy of a conceptual change instructional programme involving cognitive conflict in (1) facilitating form 2 (grade 8) students' understanding of algebra concepts, and (2) assessing changes in students' attitudes towards learning mathematics, in a mixed quantitative-qualitative research design. The…

This study explores the nature of undergraduate students' errors and misconceptions in particle mechanics. This paper provides in-depth descriptions of the errors presented by students and accounts for them in terms of students' procedural or conceptual knowledge. Specifically, this study analyses students' written responses to questions on…

Conceptual change views of teaching and learning processes in science, and also in various other content domains, have played a significant role in research on teaching and learning as well as in instructional design since the late 1970s. Conceptual change can be interpreted from different individual perspectives or from multiple perspectives. In…

The international literature suggests students frequently resort to the use of formulae when solving stoichiometry problems without understanding the concepts. In prior work we identified Thai student alternative conceptions and ability to solve numerical problem for stoichiometry. The results indicate that many Thai students also hold alternative…

Instructional strategies determine the approaches an educator may take to achieve learning objectives. Research has shown that sets of strategies or instructional models anchored on social constructivist learning theories were found to be effective in enhancing active participation. It is particularly influential and meaningful in many areas of…

Science is at heart a rational activity. Reasoning, being an important component of critical thinking has been successfully taught using Socratic methods. As an approach, the instructor or designer of instruction models an inquiring and probing mind focusing on providing questions and not answers. The main aim has been to allow learners to…

This study has two parallel research agenda: (1) the development of social skills and pedagogical content knowledge in teacher candidates as they work collaboratively in pairs, and (2) the development of conceptual understanding and social skills in elementary school students who are taught by teacher candidates with cooperative learning…

Discusses some of the misconceptions school children may have in their study of heat and temperature and attempts to clarify the concepts of temperature and to contrast it with the use of the term heat. The choice of gas thermometers as the standard temperature scale is also discussed. (HM)

The level of meaning (membership, partial association, or generalization) that English-speaking (N=1635) and Hindi-speaking students (N=823) preferred when thinking about each of 16 key concept definitions associated with the theme "the nature of matter" was measured for each concept. Results and implications for science instruction are discussed.…

The interview-about-instances technique was used to investigate the conceptual frameworks that 17 Form Four Southeast Asian students held about forces acting on an object at rest or in motion. Results show a number of alternate frameworks which are similar to those found in research conducted in western countries. (Author/JN)

Explores the extent to which key concept words are accurately identified by secondary school students. Research results on concept definition recognition from student groups in English-speaking Tasmania and Hindi-speaking India are compared. Linguistic hypothesis are presented and analyzed. (ML)

Investigates the ways children used their schemes of fractions to interpret fraction situations. Records clinical interviews with nine children (grades three through five). Reports that children do not establish relationships among different schemes when giving meaning to a given situation. (Author/YP)

Summarizes a pilot project which investigated how elementary school children in Southeast Asia learn science and mathematics concepts at different cognitive levels using the modified clinical method and group task approach. Includes the Concept Learning Project's basis, goals, phases, methodology, activities, and a summary of the findings. (DS)
