比较人类创建与AI生成的教材教授科学词汇：随机对照试验

Evidence-based vocabulary instruction is essential for literacy and content learning, yet many educators face barriers, such as lack of training and time constraints, to implementing it. Content Acquisition Podcasts (CAPs) are multimedia instruction that incorporate evidence-based practice to teach vocabulary yet can be arduous to create. This randomized controlled trial (RCT) examined whether generative AI-created Content Acquisition Podcasts–Student (CAP-S) produced vocabulary outcomes comparable to researcher-created CAP-S and whether cognitive load predicted performance. Participants inclu
