Jeanette G. Eggert Concordia University – Portland, Oregon A Comparison of Online and Classroom-based Developmental Math Courses
Developmental Math Definition: Educational opportunities for students that lack the math skills needed for success in college-level math courses. Citation
Students in Developmental Math • Traditional and Non-traditional • Previous bad experiences with math • Gaps in their background • Low self-efficacy • High levels of math and test anxiety Citation
Math Labs at Concordia • Placement test • Four half-semester courses • Cover basic skills through some intermediate algebra topics • Small class size
Before 2005 • Quizzes over each section • Large portion of class time spent in assessment supervision • Mastery-based, but time-sequencing problematic • Quiz re-takes placed additional demands on instructors
Implementation of Computer-based quizzes • Immediate feedback for students • Increased instructional time • More time for individual help
Online Math Labs • Classroom notes • Textbook resources • Quizzes • Access to the instructor • Email • Phone • In-person
This Study: Problem Statement Use existing data to compare the effectiveness of online and classroom-based developmental math courses at a four-year liberal arts university.
Theoretical Framework I Media Debate • Clark – 1983 • Delivery truck analogy • Kozma – 1991 • Instructional attributes Citation
Theoretical Framework II Instructional alternatives are needed for developmental students. Citation
Research Question #1 Is there a significant difference in successful course completion for online and classroom-based sections of the developmental math courses during the stated interval?
Research Question #2 Is there a significant difference in student satisfaction at the conclusion of each course with regard to their participation in online and classroom-based sections of the developmental math courses during the stated interval?
Research Question #3 Is there a significant difference in academic achievement in a subsequent college-level mathcourse for those students who participated in online and classroom-based sections of the developmental math courses during the stated interval?
Study Parameters • Ten semesters: Summer 2005 – Summer 2008, inclusive • Census of all students who completed developmental math courses • Parallel instructional methodologies
Human Subjects Safeguarding • Existing data • Coded to remove student and faculty identifiers • IRB approval • George Fox University • Concordia University - Portland
Data & Analysis: RQ #1Successful Course Completion • N = 718 • Classroom n = 357 • Online n = 361 • Independent samples t - test • Levene’s Test for Equality of Variances
Results: RQ #1Successful Course Completion • Classroom-based • Mean = 0.80; Standard deviation = 0.398 • Online • Mean = 0.83; Standard deviation = 0.373 • No statistically significant difference at an alpha level of 0.05 (t = – 1.039, n.s.) • Null hypothesis supported
Data & Analysis: RQ #2Student Satisfaction • N = 222 • Classroom n = 100 • Online n = 122 • Two scales; reliability via Cronbach’s Alpha • Satisfaction with course; 6 Likert-scale items • Satisfaction with the instructor; 8 items • Independent samples t - test • Levene’s Test for Equality of Variances
Results: RQ #2 - First ScaleSatisfaction with Course • Cronbach’s Alpha = 0.942 for the 6 items. • Classroom-based • Mean = 25.34; Standard deviation = 6.189 • Online • Mean = 26.55; Standard deviation = 4.398 • No statistically significant difference at an alpha level of 0.05 (t = – 1.698, n.s.) • Null hypothesis supported
Results: RQ #2 - Second ScaleSatisfaction with the Instructor • Cronbach’s Alpha = 0.971 for the 8 items. • Classroom-based • Mean = 37.29; Standard deviation = 6.091 • Online • Mean = 37.89; Standard deviation = 4.613 • No statistically significant difference at an alpha level of 0.05 (t = – 0.828, n.s.) • Null hypothesis supported
Data & Analysis: RQ #3College-Level Math GPA • N = 118 • Classroom n = 58 • Online n = 60 • Independent samples t - test • Levene’s Test for Equality of Variances
Results: RQ #3College-Level Math GPA • Classroom-based • Mean = 2.448; Standard deviation = 1.1275 • Online • Mean = 2.978; Standard deviation = 0.9076 • Statistically significant difference in the means (t = – 2.818, p < 0.05) • Both the null hypothesis and the alternative hypothesis were rejected
Summary of Results • No significant difference based on: • Successful course completion • Student satisfaction • Online instructional delivery was more effective for higher levels of academic achievement in a subsequent college-level math course.
Implications • Supports continuation of both instructional delivery systems • Revise online courses • Mastery-based • Hyperlinked • Revise classroom-based courses • Utilize web-based options • Unique face-to-face opportunities
