Yonai, Ella; Blonder, Ron – Physical Review Physics Education Research, 2020
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…

Rap, Shelley; Feldman-Maggor, Yael; Aviran, Ehud; Shvarts-Serebro, Inna; Easa, Enas; Yonai, Ella; Waldman, Ruth; Blonder, Ron – Journal of Chemical Education, 2020
In this communication paper we describe how a research-based approach was applied in Israel to support high-school chemistry teachers, who continued to teach using technology during the COVID-19 pandemic. Within the TPACK (technological pedagogical content knowledge) framework for teachers' knowledge in technological environments, we developed a…

Blonder, Ron; Mamlok-Naaman, Rachel – International Journal of Science and Mathematics Education, 2016
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…

Sakhnini, Sohair; Blonder, Ron – International Journal of Science Education, 2015
Nanoscale science and technology (NST) is an important new field in modern science. In the current study, we seek to answer the question: "What are the essential concepts of NST that should be taught in high school"? A 3-round Delphi study methodology was applied based on 2 communities of experts in nanotechnology research and science…

Blonder, Ron – Journal of Chemical Education, 2011
Nanoscience is an important new field in modern science. It deals with the ability to create materials, devices, and systems having fundamentally new properties and functions by working at the atomic, molecular, and macromolecular levels. Many teachers in the educational system have relatively limited knowledge related to nanochemistry and…
