Making decisions about the production and use of chemical substances is of central importance in many fields. In this study, a research team comprising teachers and educational researchers collaborated in collecting and analyzing cognitive interviews with students from 8th grade through first-year university general chemistry in an effort to map…

Literacy skills are critical to students' academic achievement and setting them on a path to successful high school graduation and readiness for college and careers. "Passport Reading Journeys" [TM] is a supplemental literacy curriculum designed to help improve reading comprehension, vocabulary, word study, and writing skills of…

Student conceptions related with matter and the particulate nature of matter (PNM), are vital for advanced understanding in chemistry, and have been a research area of significant attention. Lacking in the literature are studies addressing chemical misconceptions from an ontological point of view. The purpose of the current study was to develop a…

Dynamic visualizations can make unseen phenomena such as chemical reactions visible but students need guidance to benefit from them. This study explores the value of generating drawings versus selecting among alternatives to guide students to learn chemical reactions from a dynamic visualization of hydrogen combustion as part of an online inquiry…

This paper reports a cross-grade comparative study of Chinese precollege students' epistemological beliefs about physics by using the Colorado Learning Attitudes Survey about Sciences (CLASS). Our students of interest are middle and high schoolers taking traditional lecture-based physics as a mandatory science course each year from the 8th grade…

This article presents the findings of a 3-year case study that examines the lasting effects of having participated in cogenerative dialogues during a 9th grade science experience. Theo, a high school student researcher of more than three years, affords insights into the expansion of human agency, attributing it to his consistent participation in…
