A study of variations in pupils' prior knowledge for their influence on the sequencing mode of text presentation found prior knowledge reduced the effect of size of sequencing procedures. A second experiment comparing performance of pupils with low prior knowledge level using websequence and linear sequence found webteaching was superior.…

This study was undertaken to determine the effects of individualized instruction on enrollment, attrition, achievement, and student attitude in a general biology course for non-science majors. Fifteen auto-tutorial minicourses were designed for use in the laboratory part of the course, each consisting of a printed study guide, slide-tape module,…

Reviews literature relating to educational courseware evaluation and the need for context-bound evaluations. Highlights include the promise of educational technology; implications for online learning; technological developments, including use of the Internet in education; comparing modes of delivery; examples of context-bound evaluations; and the…

This study contrasted college-level computer assisted instruction modules with various ratios of higher cognitive to factual questions and highlights to determine the effectiveness of highlights and question formats. Results indicate that, regardless of the ratio of higher cognitive to factual questions, modules containing questions are superior…

This study exploring ways in which educational technology might be used to provide better schools for less money focuses on technological applications utilizing instructional radio, instructional television, computer-assisted instruction, computer-managed instruction, and programmed instruction. Based on a review of the literature on the costs and…

Focusing on the achievement and motivational effects of analogies of varying enrichment levels when used with abstract, unfamiliar, and difficult content, this study examined their effects on instruction at the recall and application levels using content consisting of both concepts and principles. The subjects were 123 eighth-grade science…

A review of the research on correspondence education with emphasis on its two-way communication aspects introduces this report on a series of studies designed to shed light upon problems related to the design and delivery of correspondence instruction. A total of 1,805 adult students enrolled in regular Swedish, Norwegian, and British…

Two studies investigated robustness of the effect of precise elaborations on memory and relationship of these effects to metacognitions about learning. Sentences which were elaborated in different ways were read to subjects by experimenters to establish levels of meaningfulness and identify effects on performance. Comprehension and confidence…

Two studies were conducted to compare the advance organizer and concept elaboration models of instruction with a task analysis approach. It was hypothesized that the concept elaboration group would achieve significantly higher than either the advance organizer group or the task analysis group on concept learning and principle learning. A pilot…

This study investigated effects of rehearsal strategies and immediate test formats on delayed retention and effectiveness of visualization on material acquisition and retrieval. Findings indicate different rehearsal methods have different effects in facilitating delayed retention. Information acquisition is facilitated by visualization, although…

This study examined the effects of the type of adjunct questions (use-a-generality, remember-a-generality, and remember-an-instance) and the position of these questions either before the relevant text passage (pre-questions) or after it (post-questions) on the three corresponding performance levels of learning. The subjects were 74 eighth-grade…
