Should the decision of whether to lecture be influenced by what we are teaching in class that day? Are some kinds of content better explained by the teacher than discovered by the students? Is it complex content that you know from previous experience often causes students to struggle? Can the teacher’s explanation lay the foundation, set the parameters, or provide the context so that students can start dealing with content from a place that expedites understanding? Is a lecture the best way to clarify what students find confusing?
