As science education moves toward lab-based courses, what happens to students without access to a lab? One option is peer-led team learning (PLTL), a cooperative-learning strategy that encourages students to actively engage in learning. Snyder et al. hypothesized that a PLTL model would lead to increased achievement for students not enrolled in an optional lab course. Non–lab course PLTL students participated in active problem-solving, resulting in this group averaging a letter-grade higher than their nonlab peers without PLTL. This difference was statistically significant, suggesting that PLTL workshops almost entirely closed the achievement gap for students without access to a lab. Although successful, the authors caution against using PLTL workshops as a replacement for laboratory experience.
