Learner-Centered Astronomy Teaching: Strategies for Astro 101
Timothy Slater and Jeffrey Adams
Slater and Adams are leaders in astronomy education research. Prentice-Hall made this short paperback available at low cost. In 167 pages, it contains everything that an instructor needs, from background research, to course design, lecturing for active participation, small-group collaborative learning, writing effective multiple-choice items (and alternatives thereto), course evaluations — even tips on creating a teaching portfolio. It has many useful appendices, including sample questions and tasks and learning objectives, and the well-tested Astronomy Diagnostic Test. A model for how to provide instructors with practical, research-supported material!
