Texts play an integral role in science research and science classrooms yet biology textbooks have traditionally failed to reflect the epistemic elements of the discipline such as justification of claims and visual representations of empirical data. This study investigates high school biology students' reading experiences when engaging more…

The theoretical construct of teacher noticing has allowed mathematics teacher educators to examine teacher thinking and practice by looking at the range of activities that teachers notice in the classroom.

This study reports on the development of a method in which trained reviewers, following a set of guidelines defining the ideas to be…

Adopting a neo-Piagetian conceptual framework and a phenomenographic approach, we identified students' conceptual progression pattern on matter from elementary to high school. We interviewed 54 students from Grade 1 to Grade 10 chemistry on their conceptions of substances (i.e., water, vinegar, and baking soda) and the combining of the substances.…

The case-based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual…

This article explores the conceptual change of students in Grades 10 and 12 in three Australian senior high schools when the teachers included computer multimedia to a greater or lesser extent in their teaching of a genetics course. The study, underpinned by a multidimensional conceptual-change framework, used an interpretive approach and a…
