Problem solving likely involves at least two broad stages, problem space representation and then problem solution (Newell and Simon, Human problem solving, 1972). The metric centrality that Freeman ("Social Networks" 1:215-239, 1978) implemented in social network analysis is offered here as a potential measure of both. This development research…

This experimental investigation replicates previous investigations of the effects of left margin screen background color hue to signal lesson sections on declarative knowledge and extends those investigations by adding a measure of structural knowledge. Participants (N = 80) were randomly assigned to receive 1 of 4 computer-based lesson treatments…

Although feedback is an important component of computer-based instruction (CBI), the effects of feedback on higher-order learning outcomes are not well understood. Several meta-analyses provide two rules of thumb: any feedback is better than no feedback and feedback with more information is better than feedback with less information. …

Considers the effects of feedback on memory with an emphasis on retention of initial error responses. Applies a connectionist approach to explain feedback effects. High school students completed a computer-based lesson with either delayed feedback, single-try immediate feedback, or multiple-try immediate feedback. Findings indicate a connectionist…

An earlier review by the author reported an aptitude-treatment interaction (ATI) relating instructional feedback and prior knowledge. For low prior knowledge learners, single-try feedback (STF) was slightly superior to multiple-try feedback (MTF), while for high prior knowledge learners, MTF was superior to STF. In the current report, raw score…

Considers the effects of an Integrated Learning System (ILS) on the mathematics test scores of elementary school children. Results indicate that ILS software had its greatest effect on mathematics concepts scores, which is contrary to the commonly held opinion that mathematics software is effective primarily in drill and practice of computational…

Focusing on whether computer-based study tasks should use multiple-choice or constructed-response (CR) question formats, this study hypothesized that a CR task with feedback would be superior to multiple-choice study tasks that allowed either single or multiple tries (STF, MTF). As hypothesized, CR scores were larger than MTF and STF scores,…

Colour is a common feature in computer-aided learning (CAL), though the instructional effects of screen colour are not well understood. This investigation considers the effects of different CAL study tasks with feedback on posttest performance and on posttest memory of the lesson colour scheme. Graduate students (n=68) completed a computer-based…

A study involving 50 experimental and 99 control subjects (graduate education majors) was undertaken to assess the interchangeability of knowledge of correct response feedback (KRC) and answer until correct feedback (AUC) in computer-assisted instruction. P. L. Smith's model (1988) suggests that AUC in better for high-ability students. W. Dick and…

Examined the effect of providing progress reports for 24 weeks to first and second graders in a computer-based instruction environment. Results indicated that providing progress reports may produce small, short-term gains in rate of lesson completion for some students. (BC)

Compared the grade level difficulty obtained from seven readability formulas to student reading levels from two national standardized tests to determine which formulas best determined the readability of computer-based text. Found that the Flesch-Kincaid, FOG, and ARI formulas provided the best estimate of reading grade level of computer-based text…

A WICAT Computer Assisted Instructional (CAI) System began operation at St. Anne Consensus School (Tennessee) in August, 1986. Iowa Test of Basic Skills (ITBS) scores for the years 1984 through 1988 for ten students in each of the grades 4th through 8th (as of May 1988) were analyzed. The average gain for all subjects during the two years before…

Reviews previous research to compare the instructional effects of multiple-try feedback (MTF) forms to single-try feedback forms and no feedback in both traditional and in computer-based instruction. Interaction between students' prior knowledge and the number of feedback trials is examined, and future MTF research is suggested. (Contains 59…

This paper considers some practical concepts and ideas related to standardized test score improvement in general and specifically to the World Institute for Computer-Assisted Teaching (WICAT) Integrated Learning System (ILS) use. Previous research cited in this paper shows that, while teachers are the most important variable in ILS utilization,…

In a study involving three diverse computer assisted learning (CAL) experiences and different learner populations (13- and 14- year olds, 19-21- year olds, and adult education majors), a general shift in learning style (Kolb) was observed. The magnitude of the shift appeared to vary with learner ability and exposure to CAL. (PEN)
