This paper examines the process of high school students' planning investigations in the chemistry laboratory across two consecutive academic years in terms of their actions and their progress. The context is a set of five inquiry-based laboratory tasks in which participants (9th and 10th graders, 14-15 and 15-16 years of age) are required to plan…

To determine whether a suite of audible adaptive technologies would increase the hands-on participation of high school students with blindness or low vision in chemistry and physics courses, data were examined from a multi-year field study conducted with students in mainstream classrooms at secondary schools across the United States.

This paper describes a mini-project developed with 10th grade Portuguese students where, by using an experimental activity involving the use of natural dyes to colour wool, students acquired a better understanding of the concepts and relationship between the colour, the electromagnetic spectrum, and chemical bonding. As demonstrated by the results…

The aim of this study was to create an instrument to measure elementary teachers' interest in teaching chemistry. The interest in chemistry teaching instrument (ICTI) was created to measure both the affective and cognitive components of interest. After establishing the face and content validity of the instrument, the internal consistency of the…

In an era in which information is rapidly growing and changing, it is very important to teach with the goal of students' engagement in life-long learning in mind. This can partially be achieved by developing transferable thinking skills. In our previous paper--Part I, we conducted a review of the transfer literature and suggested a three-attribute…
