Melissa V. Rentchler discusses improving library instruction by going beyond lectures and integrating critical thinking strategies and technologies. She references Edgar Dale's Cone of Learning model and research by Fadel and Lemke on multimodal learning. Fadel and Lemke's research found that multimodal learning using visuals and interactivity can improve both basic and higher-order learning when topics are moderately complex. The most effective instruction designs incorporate various media, combinations of modalities, levels of interactivity, learner characteristics, and pedagogy based on each unique learning situation.
