Nanotechnology has been touted as the next 'industrial revolution' of our modern age. In order for successful research, development, and social discourses to take place in this field, education research is needed inform development standards, course workforce preparation. addition, there a growing need educate citizens students about risks, benefits, ethical issues related nanotechnology. This position paper describes advancements that have made nanoscale science nanotechnology, challenges...
Imagine being locked in a chemical lab with 4 "bombs" that will detonate within 60 min unless you neutralize them. You now must use your brain, knowledge, intuition, and need bit of luck to the bombs escape unharmed... This is concept behind "chemical escape", an activity for high-school students, which brings extremely popular genre "escape rooms" into chemistry classroom; it engages students learning, increases motivation, bridges gap between classroom real world, as well allows teamwork...
Although understandings of scientific inquiry (as opposed to conducting inquiry) are included in science education reform documents around the world, little is known about what students have learned during their elementary school years. This partially due lack any assessment instrument measure inquiry. However, a valid and reliable has recently been developed published, Views About Scientific Inquiry (VASI; Lederman et al.

Sixteen experienced participated course skills use Israel. Research tools consisted (1) pre-post questionnaire, (2) interviews with teachers, (3) an analysis they edited (which...
Discussions held in the chemical education community have generated a variety of reports and recommendations for reforming chemistry curriculum. The refer to teaching context real-world issues. This has been suggested as way enhance students' motivation. It is that problems emphasize interdisciplinary nature relevance lives. An attempt was made incorporate these into by analytical together with environmental chemistry. A unit incorporating an developed, which students learn concepts specific...

A nanotechnology module was developed for ninth grade students in the context of teaching chemistry. Two basic concepts were chosen: (1) size and scale (2) surface-area-to-volume ratio (SA/V). wide spectrum instructional methods (e.g., game-based learning, learning with multimedia, models, project based storytelling narratives) implemented to support students' understanding. Students' interviews content final projects used analyzed learn how using a variety influenced understanding...
Chemical escape rooms (ChEsRms) are educational games in which students use their brain, chemical knowledge, intuition, and a bit of luck to solve mystery. At the Weizmann Institute, we have developed ChEsRms that implemented by teachers classes. Since COVID-19 pandemic stopped all activities took place physical space, decided design virtual ChEsRm (VChEsRm) is fully conducted digital space. We describe principles characterize VChEsRm present students’ teachers’ perceptions how it differs...
Abstract Artificial intelligence (AI) has made remarkable strides in recent years, finding applications various fields, including chemistry research and industry. Its integration into education gained attention more recently, particularly with the advent of generative AI (GAI) tools. However, there is a need to understand how teachers’ knowledge can impact their ability integrate these tools practice. This position paper emphasizes two central points. First, teachers technological...
Abstract This paper discusses the ethical considerations surrounding generative artificial intelligence (GenAI) in chemistry education, aiming to guide teachers toward responsible AI integration. GenAI, driven by advanced models like Large Language Models, has shown substantial potential generating educational content. However, this technology’s rapid rise brought forth concerns regarding general and use that require careful attention from educators. The UNESCO framework on GenAI education...
The rise of digital technologies since the second half 20th century has transformed every aspect our lives and had an ongoing effect even on one most conservative fields, education, including chemistry education. During Covid-19 pandemic, teachers around world were forced to teach remotely. This situation provided authors with opportunity investigate how integrate technology into their teaching, compared research literature suggests that it is done. theoretical framework used in this...
Inclusion of a diverse group students, both regular learners and with special needs in chemistry classrooms is an important goal educators. However, alternative conceptions among high-school students can be barrier for completing the learning process classroom, especially heterogeneous class. This study aimed to examine differentiated instruction (DI) classroom. We evaluated how customized pedagogical kits (CPKs) DI, which aim overcome found during instruction, affected teachers. paper...
