Students in introductory college physics often have wide ranges of preparation, making it challenging to deliver effective instruction for all. While numerous educational products and strategies have been shown to be broadly effective, there is a need for research-based online materials that support personalized learning and focus specifically on improving problem-solving abilities. Building from our Interactive Video Vignettes (IVVs), we are developing freely available Interactive Video-Enhanced Tutorials (IVETs). These combine videos of real instructors who guide students through an expert-like problem-solving process using a series of required questions that motivate students to interact with the material. Research on the effectiveness of the IVETs is underway and preliminary results are encouraging.
