Chemistry

This paper argues for addressing histories of scientific institutions and their entanglements with Euro-American imperialism, racial capitalism, and environmental injustice in secondary science education. Our argument is grounded in the history of a multinational chemical corporation that operates a chemical plant in a neighborhood where one author lives and the other teaches. We illustrate how analysis of the plant inspired youth participatory science projects by describing how considerations about the plant were connected to chemistry curricula.

These high-quality, NGSS-aligned science lesson plans are built on phenomena meaningful to rural students. They include plans for middle school science, as well as high school biology, Earth science, chemistry, and physics.

This collection offers K-12 curricula, activity guides, and other resources to support hands-on, inquiry-based investigations of the ecosystems and organisms around us. Themes include: Hudson River ecology, urban ecosystems, schoolyard ecology, biodiversity, water and watersheds, and data exploration and nature of science. Additional resources are available for home and distance learning.

Situated in the context of advanced placement (AP) reform in the United States, we investigated profiles of teachers’ motivation for participating in professional development (PD) courses in a two-cohort sample of n_t1 = 2,369 and n_t2 = 2,170 chemistry teachers via multilevel latent class analysis.

Aqueous solutions have proved to be a challenging topic for chemistry students at all levels. An understanding of what is happening at the molecular level in aqueous processes such as dissolution is key to understanding the macroscopic properties of the system as well as to communicating fluently with chemical symbols. In this study, we examined the storyboards of 28 high school students in the United States who participated in a series of lessons employing the VisChem Approach that addressed the topics of liquid water, solid sodium chloride, and finally sodium chloride dissolution in water over the course of a year.
