New Direct Measurement Videos allow students to vary parameters, and to select and position measurement tools. For example, a Gen-2 DMV allows students to vary the constant force on a cart to measure the resulting acceleration. Students can plot the relationship between force and acceleration. With these new tools, students can make decisions about how best to analyze the situation.

I'll show examples of how this has been implemented in my classroom, and on the MIT and BU physics MOOCs, and discuss preliminary results from last summer's AB testing in the MIT MOOC.

I'll also discuss how students can use DMVs and measurement uncertainty to explore the limits of the simplified models.

The weekly calendar is also available via subscription to the physics-announce mailing list, and by RSS feed.
