Research on a Lecture-Tutorial Approach to Teaching Introductory Astronomy for Non-Science Majors

摘要: The Lecture-Tutorial curriculum development project produced a set of 29 learner-centered classroom instructional materials for large- enrollment introductory astronomy survey course non-science majors. Lecture-Tutorials are intended use by collaborative student learning groups, and designed to be integrated into existing courses with conventional lectures. These offer classroom-ready activities that do not require any outside equipment or drastic revision implementation.
