Table 1.
Student confidence and student learning were measured in 10 classes in the spring of 2015. Five of these were standard class sessions and five were “molecular sculpting” sessions. Each 80-minute class session had varying degrees of time dedicated to student writing (W), lecture + “chalk talk” (L + C), student discussion (D), videos (V), sculpting (S), and miscellaneous items (M) such as relating lecture sessions to lab content, reviewing midterms, or recapping topics learned in prior class sessions.
