The document discusses active learning strategies that can be used in classroom lectures. It begins by defining active learning as involving students in higher-order thinking skills like analysis and evaluation, rather than just transmitting information, and engaging students through activities like discussions. A variety of specific in-class active learning techniques are then presented across multiple slides, including opening a lecture with a question, think-pair-shares, focused listing, brainstorming, planned breaks for questions, and blank slides to pause presentation. The document emphasizes that these strategies encourage student engagement, prepare them to learn, and provide instructors feedback.
