This document describes a flipped classroom model used in a GIS course. In a flipped classroom, instructional content is delivered outside of class time through online videos and readings. Class time is used for hands-on activities and addressing students' questions. The author flipped her introductory GIS course by having students watch lecture videos and complete readings, quizzes, and discussions through an online wiki before class. This allowed for more lab and interactive work during class to reinforce concepts. Student reviews of this approach were positive, noting benefits like learning at their own pace and having more one-on-one support from the instructor.
