The high-school chemistry curriculum is loaded with many important chemical concepts that are taught at the high-school level and it is therefore very difficult to add modern contents to the existing curriculum. However, many studies have underscored the importance of integrating modern chemistry contents such as nanotechnology into a high-school curriculum. When students are exposed to nanotechnology, they perceive chemistry as more relevant to their life, and more modern than the chemistry they usually study at school, and consequently, their continuous motivation to study chemistry and related subjects increases. In the current study we identified topics in the high-school chemistry curriculum in Israel into which the essential nano-scale science and technology (NST) concepts can be integrated. Insertion points for all 8 NST essential concepts were found. We discuss the importance of ways in which chemistry educators can implement the results for updating the chemistry curriculum, thus making it more modern and relevant to the actual chemistry research that is conducted.

Even when chemistry teachers’ beliefs about assessment design align with literature-cited best practices, barriers can prevent teachers from enacting those beliefs when developing day-to-day assessments. In this paper, the relationship between high school chemistry teachers’ self-generated “best practices” for developing formative assessments and the assessments they implement in their courses are examined. Results from a detailed evaluation of several high school chemistry formative assessments, learning goals, and learning activities reveal that assessment items are often developed to require well-articulated tasks but lack either alignment regarding representational level or employ only one representational level for nearly all assessment items. Implications for the development of a chemistry-specific method for evaluating alignment are presented as well as implications for high school chemistry assessment design.
