Evaluation of an Interactive Tutor on Sampling (original) (raw)

2003

Abstract

Through support from the National Science Foundation (DUE-9752619), I have been developing a computer-based, interactive tutor teaching the fundamentals of sampling. Several principles of cognitive learning and instructional design are implemented in the design: contextualized (social science) learning, cognitive mapping for relational learning, building of formal-operational understanding from concrete imagery, self-directed learning, and corrective, directive, and evaluative feedback. The tutor runs on PC platform and was developed using Macromedia Authorware/Director software, along with several auxiliary programs, such as MathCad. The effectiveness of the first fully operational version of the program was evaluated by using an experimental design involving two sections (approximately 65 students) and two faculty. Within each section, half the students were assigned to study sampling concepts and procedures using the Sampling Tutor without attending lectures. Two different lectur...
