The project involved simultaneous development of content design, instructional strategies, software, and hardware, with a principal focus on evaluation of the instructional videodisc in the classroom.…

Reports on use of a tutorial program written in STAF2 authoring language to replace human teaching in an undergraduate biology mastery learning program. Learning was assessed cognitively in terms of Bloom's Taxonomy. Students taught by the STAF2 computer program attained significantly higher scores for retention, application, and evaluation of…

This investigation of the impact of an Individualized Audio-Tutorial (IAT) biology learning unit upon students in five ninth grade classrooms in an urban junior high school in Israel focused on the students' perceptions of their classroom learning environment, and their attitudes toward IAT and toward science and understanding the process of…

To detemine the effectiveness of the Individualized Audio-Tutorial (IAT) method of instruction, an IAT unit in biology was implemented in ninth grade classrooms in an urban school in Israel, and student achievement was measured in relation to gender, academic background in mathematics and biology, and IQ levels. The 180 subjects were randomly…

The purpose of this study was to examine how learners with different levels of prior understanding of a topic interact and learn from computer-assisted video instruction systems when they have control of content, sequence, pace, and mode of instruction.
