This study explored how using computer simulations helped 7th grade students improve their understanding of chemistry. At my school, many students are below grade-level in reading and math, which can make science more challenging. During a 3-week chemistry unit, I used simulations from Amplify and other online tools. These simulations allowed…

When thinking about measurement uncertainty in a laboratory experiment that features quantum mechanical effects, it is important to consider both the physical principles of underlying quantum theory (e.g., the uncertainty due to quantum mechanical superposition states) as well as the limitations of the measurement (e.g., the spread in outcomes due…

Technology is changing the way students interact with knowledge, and open-ended activities are one of the main types of tasks that students engage with in technology-rich environments. However, the amount of guidance needed to promote learning in these environments remains unknown. We explore this issue by focusing on the effects of step-by-step…
