LECTURE TUTORIALS: AN EFFICIENT WAY TO DECREASE STUDENT MISCONCEPTIONS IN INTRODUCTORY GEOSCIENCE COURSES
Currently, we have constructed Lecture Tutorials for a wide range of topics, a sampling of which includes the following: the interpretation of plate boundaries, the relation of grain size and rate of crystallization in igneous rocks, the conditions under which earthquakes generate life-threatening tsunamis. These Lecture Tutorials have been tested with pre- and post- questions at three different schools (two community colleges and one state university). Students scored an average of 60% on multiple choice questions asked after the lecture but before students completed the Lecture Tutorial. After the Lecture Tutorial, the students' average score increased to 79%. A subset of these questions is from the reliable and validated Geoscience Concept Inventory (GCI). On the GCI questions, students scored 62% on the questions asked before the Lecture Tutorial but after lecture, and the scores improved to 79% after the Lecture Tutorial.
Our presentation will include examples of Lecture Tutorials, as well as access to the complete set of Lecture Tutorials developed to date.
