Current Research: My research program centers on basic encoding and retrieval processes in human learning and memory. One particular focus is on how the act of retrieval enhances subsequent memory, as observed in the testing effect. I am particularly drawn to learning and memory phenomena with direct applications to teaching and student learning. My work therefore has both a theoretical and applied orientation.

Applied Memory Lab: My lab group conducts research on various topics in the area of applied learning and memory. Questions center on basic learning and memory principles, but with an eye toward phenomena that may be applied in educational settings to enhance teaching and student learning. As an example, my students and I have published a number of papers in recent years on the so-called testing effect, the finding that memory tests may enhance subsequent memory for tested information. This benefit of testing, consistently observed in the well-controlled conditions of the lab, also extends to educational settings. Tests not only assess what students have learned, but also enhance learning for tested material. With this in mind, several applied projects in my lab have examined the effectiveness of practice quizzes, instructor questioning, and study-strategy instruction on student performance. The take-home message? Don't just read and re-read. Don't just study and re-study. Instead, take some of that time you would've devoted to re-reading or re-studying, and use it to engage in practice testing. Or get together with classmates and test each other. Research in well-controlled laboratory conditions as well as real-world classroom environments shows that you can expect this practice testing to enhance your learning of the information and boost later test performance.
