Abstract:

Through support from the National Science Foundation (DUE-9752619), an interactive tutor teaching fundamentals of sampling was developed. The tutor's architecture, based on cognitive learning principles: contextualized learning, conceptual mapping, grounding formal understanding in concrete imagery, self-directed learning, and evaluative feedback. The authoring software used to deliver the tutor, Macromedia Authorware/Director, also tracked several user behaviors: time on task, navigation behavior, use of multimedia features, and review question performance. The software will be briefly demonstrated. This paper reports the evaluation of knowledge gained (pre-post test comparison) about sampling as a function of tutorial user behavior among 120 students from two social science Quantitative Research courses. Hypotheses are examined regarding the effectiveness of different student navigation patterns, time on task, number of learning sessions activated, time spent on specific content modules--including a recitation section assessing student declarative and performance knowledge and giving feedback, and use of conceptual mapping displays.
