This study sets for itself the task of constructing a learning trajectory for the fundamental theorem of calculus (FTC) that takes into account the interaction with an educational digital tool. Students were asked to explain the connections between interactive and multiple-linked representations in an educational digital tool, and to conjecture…

In light of the recent growing interest in conceptual learning and teaching of calculus, and especially with the focus on using technological environments, our study was designed to explore the learning processes and the role played by multiple-linked representations and by interactive technological environment in objectifying the accumulation…

Chemistry students in Israel have two options for studying chemistry: basic or honors (advanced placement). For instruction in high school honors chemistry courses, we developed a module focusing on abstract topics in quantum mechanics: Chemistry--From the Nanoscale to Microelectronics. The module adopts a visual-conceptual approach, which…

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…

How often do our students long for black and white rather than the shades of grey that history generally presents us with? Understanding the Arab-Israeli conflict is all about understanding diversity and complexity in all their shades of grey. Alison Stephen, teaching in an immensely diverse school herself, is determined not to over-simplify the…

Information on the content of the intended science curriculum, what science was actually taught by the teachers, and how that science was taught is presented. Student achievement and attitudes were assessed using tests and questionnaires. Data were obtained from teachers regarding whether the content had been taught to the students (n=657) who…
