Using three-dimensional models in chemistry is a common teaching practice aimed at elevating the level of understanding of abstract concepts. However, the experience of using chemical models is still quite passive in terms of students' input, requiring the students to utilize mainly visual, auditory, and some tactile information processing…

Professional development courses help teachers integrate new content knowledge into the high-school curriculum. Designing practical online courses for this purpose is challenging, particularly in emerging fields such as nanotechnology. In this study, we evaluated such a course in three complementary dimensions: (1) knowledge, (2) the complexity of…

The goal of this research is to provide a rich set of connections between two fields: (i) Nanoscale science and technology (NST) and (ii) topics from a common middle school physics curriculum. NST is emerging as one of the most promising new fields of the 21st century, which is one of the many arguments for including NST topics in secondary…

This study focused on teachers' transfer of a variety of teaching methods from a teaching module on nanotechnology, which is an example of a topic outside the science curriculum, to teaching topics that are part of the chemistry curriculum. Nanotechnology is outside the science curriculum, but it was used in this study as a means to carry out a…
