Differential benefits of situated instructional prompts

摘要

Learners often neglect support (glossaries, help sites etc.) in computer-based learning environments since they experience it as an unrelated add-on. We assumed that prompts presenting situated instructional support would lead to an increased use of help sites and glossary. Further it was assumed that situated instructional support would lead to a higher cognitive load of learners, which causes differential learning outcomes depending on learners’ general domain knowledge. To scrutinise the differential effect of situated instructional prompts we conducted an experiment with 69 students (undergraduates vs. graduates). Students learned either with a learning environment with or without prompts. As expected, learning with prompts resulted in an increased support usage. Furthermore, two interaction effects occurred. (1) Graduates learned slightly better with a program including prompts whereas undergraduates performed better without prompts. (2) Undergraduates stated a higher perceived cognitive load if they learned with a program with situated instructional prompts. In the group of graduates no differences occurred concerning the perceived cognitive load. The results are interpreted within the framework of cognitive load theory.
