Hypertext researchers and designers contend that the hypertext information structures may reflect the semantic structures of human memory. Further, they believe that mapping the semantic structure of an expert onto hypertext information structure and explicitly illustrating that structure in the hypertext will result in improved comprehension…

The effects of three types of feedback in a computer-assisted instructional lesson--knowledge of the correctness of response (KOR), knowledge of the correct answer (KCR), and explanatory feedback in combination with or without a second try on error correction--were investigated, using a 2 by 3 factorial design. The results indicated that…

This study examined problem solving as a function of display type (table/graph) and numeric function (linear/nonlinear) in four problem solving domains. Twenty-two stimulus problems were developed, and line graph and table displays were constructed for each problem. Half of the displays contained linear numeric functions and the other half…

Describes a two-part study involving 14- to 15-year-old high school students in New South Wales (Australia) that compared two modes of responding to free response examination questions: by computer and by pen and paper. Discusses results of analysis of variance. (Author/LRW)

This study assessed the effects of providing learners with a graphic illustration of coordinate concept relationships to supplement learning from text-based instruction. Seventy-three undergraduate students were given a passage of approximately 1,200 words in length, describing Ausubel's Categories of Meaningful Learning. Half of the students also…

This study investigated the effects of sequence and synthesis prescriptions from the Elaboration Theory by teaching the parts of a microcomputer system based on a parts-conceptual structure. A 2x3 factorial design was used which incorporated two sequences, general-to-detailed and detailed-to-general, and three levels of synthesizer, i.e., no…

The effect of the interaction between cognitive style differences (field dependence/field independence) and various degrees of visual complexity on pictorial recall memory was explored using three sets of visuals in three different formats--line drawing, black and white, and color. The subjects were 86 undergraduate students enrolled in two core…

The relationship between field dependence-independence (FDI) and the ability to read and comprehend printed text was examined in this study. The effect of the structure of instructional text on the learning process of individuals at various points on the continuum of FDI was also studied. The following hypotheses were developed: (1) there would be…

This study determined the effects of using an instructional game and supplemental readings on student motivation as defined using the ARCS model of motivation and performance. Subjects were 75 undergraduate education majors enrolled in a required educational psychology course at a large southwestern university. All students attended a lecture on…

An experiment was conducted to examine the effects of presentation mode, picture content, and serial position upon the recall of brief television news items. Fifteen items were presented in either video- or audio-only mode to 40 subjects. The results are discussed in terms of various imagery hypotheses. (Author)

This study examined the influence of textual display in printed instruction on the attention, performance, and preference of 90 preservice teachers, and investigated differential effects of textual display for high and low ability learners. Textual display was operationally defined as the arrangement of specified elements on the printed page, and…

This study investigated the effects of computer and print text density on learning, and the nature and effects of learner preference for different density levels in both print and computer presentation modes. Subjects were 48 undergraduate teacher education majors, who were assigned at random to six treatment groups in which a statistics lesson…

The purpose of this study was to examine the effects of instruction that is organized in two alternative formats--hierarchical (Gagne, 1962) and elaborated (Reigeluth, 1979)--on learner's recall and application of content-specific principles. Sixty-nine college juniors and seniors enrolled in an education media production course studied one of two…

Describes study of 122 undergraduate and graduate students that contrasted the effects of two error correction procedures on student achievement when using computer assisted instruction. Analyses of variance were used to determine whether question type or error response affected subsequent responses to factual and higher cognitive questions.…

Describes study that investigated the effects of computerized test administration on undergraduates' responses to the Minnesota Multiphasic Personality Inventory (MMPI), and discusses methodological considerations important in evaluating the sensitivity of personality inventories in different administration formats. Results analyze the effects of…
