From the experiential learning perspective, this study investigates middle and high school students (n = 1009) who used an online module to learn about wildfire hazards, risks, and impacts through computational simulations of wildfire phenomena. These students were taught by 18 teachers in urban, rural, and suburban schools across the United States. We analyzed students’ simulation behaviors captured in log files, responses to an assessment administered before and after the module, and demographic surveys, as well as teachers’ responses to a post-module implementation survey.

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. In addition, the study investigated to what extent profile membership was related to factors at the teacher, school, and PD levels.

This article explores science teachers’ implementation of science and engineering practices (SEPs) under different instructional settings. We compared the number of SEPs science teachers reported using in face-to-face instruction (traditional), online-only instruction (virtual), or HyFlex instruction (synchronously online and in-person) from August 2020 to May 2021. Records and artefacts of the teachers’ instructional practices were collected over three one-week periods.

Our 5D assessment development process is eight phases, each with a clear goal and tools to support task development. The tools and processes are combined in the 5D Assessment Development Tool for easy access from a single source.

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.
