This study examined the types of mathematical connections established by four secondary school students while constructing concept maps on transformations of the parabola. The use of concepts maps revealed students' understandings--including some misconceptions--of transformations of the parabola and confirmed the usefulness of a model for…

This study explored how senior high school students apply their conceptual knowledge, consisting of theoretical and system knowledge, to think critically when confronted with technological issues. We employed a curriculum on the history of communication technology to teach students about basic concepts in communication technology and to cultivate…

Students bring with them their own misconceptions to the science classes and it becomes a barrier in developing new concepts. Therefore, identifying misconceptions is an essential component in teaching science. The objective of this study was to identify 10th grade students' misconceptions on plant transport with the use of two-tier diagnostic…

Being a class room teacher in rural areas for more than two decade's author has observed that rural area learners are suffering from multi faced learning barriers. Conceptual understanding and reasoning capacity is very poor and they are performing poorly in their school based examinations. Aim of this paper is to present a suitable, cost…

This article describes the outcome of an exercise carried out with one hundred undergraduate student teachers (preservice teachers) enrolled in a Biology Teaching Methods course, a third year course in a four-year Teacher Education Programme. The students, working in groups of three to four, were assigned to construct a concept map showing their…
