Abstract

This article reviews the affordances of multimedia-based Problem-based learning (PBL) and its applications for the teaching and learning of nanotechnology to elementary students. The content of a web-supported module on nanomaterials is reviewed, and its effectiveness for guiding informed decision-making among elementary students choosing between sunscreens containing nano-sized particles and regular-sized particles is discussed. Outcomes of the module include significant gains in elementary students’ science conceptual understanding, attitude towards science, and societal risks and benefits of nanotechnology. The use of multimedia-based modules may provide instructional support to teachers who hope to inform students of the importance of hands-on science and the scientific method that should drive the decision-making process by elementary students. Recommendations for teaching are discussed with implications for policy and integrating artificial intelligence into PBL.
