PERFORMANCE AND ATTRITION RATES OF STUDENTS IN ONLINE VERSUS FACE-TO-FACE PHYSICAL GEOLOGY COURSES
Student performance was measured using two metrics: 1) composite student grades (on a 4.00 scale) for each physical geology section, and 2) the percentage of students that attained a grade of C or above. The attrition (drop) rate was calculated using the permanent enrollment (a 14-day census at UTM) and the number of students who dropped or withdrew from each physical geology section. The high school students (n = 20) taking dual credit physical geology courses exhibited the highest performance (mean GPA of 3.69 and 100% of the students attaining a C or higher) and the lowest attrition rates (0 %). Traditional on-campus students (n = 1091) performed the lowest with a mean GPA of 2.13 and with only 71 % of students attaining a C or higher grade. The drop rate for on-campus students was 5 %. Off-campus students (n = 40) taking physical geology had a mean GPA of 2.62 with 81 % earning a C or higher grade and 4 % attrition rate. Online students (n = 80) had a mean GPA of 2.38 with 78 % earning a C or higher grade, which was better than the traditional on-campus students; however, the attrition rate among online students was 26 %.
Variations in student performance and attrition are attributed the different modes of delivery (online vs. face-to-face) and the differences in student demographics (traditional on-campus vs. high school vs. non-traditional students). Intervention strategies for reducing student attrition will be discussed.
