When using spreadsheets to explore real-world problems involving periodic change, students can observe what happens at each period, generate a graph, and learn how changing the starting quantity or constants affects results. Spreadsheet lessons for high school students are presented that explore mathematical modeling, linear programming, and…

This article provides a rationale for educators to use multimedia computer technologies to create individualized computer-based instructional materials for students with autism. Software design guidelines based on empirical research are presented, along with detailed descriptions of two multimedia authoring systems for educators. Suggestions focus…

Describes the initial implementation and evaluation of an online environment designed to support a collaborative programming task among undergraduate students and provide them with experiential learning. Explains a holistic, context-based approach to evaluating the success of the innovation, together with the framework used for conducting the…

A study of college students revealed weaknesses in learning strategies and metacognitive skills. The students' experience using LOOPS simulation software to create program loops suggests that computer programming coursework may have substantial value for non-majors. (LRW)

Computer-based teaching is ineffective when instructional systems are designed emphasizing technology rather than course information. In view of this, the development of NEAT (Integrated Environment for Authoring in ToolBook) at Acadia University (Nova Scotia) is discussed. Other topics include intelligent tutoring systems, a question repository…

Presents a scenario in which two people solve a programming problem by discussing various number sequences and functions. The problem is redefined as one related to number theory and operations research. (DDR)

Uses content analysis of television characters in all occupations across 30 seasons to test the argument that television entertainment depicts business negatively. Reaffirms that television stigmatizes the occupation of business, independently of economic factors. Notes that these results pose a challenge to mass communications theory that…

Examines the effects of using LOGO, or problem-solving- oriented simulation software on locus of control, self-esteem, and achievement motivation for fifth-grade students. The importance of these variables in predicting LOGO mastery and far-transfer problem-solving ability was also examined. (Author)

Describes the Text Encoding Initiative (TEI) guidelines' approach to describing hypertext features. Discusses the rationale behind the design of the tagset and the range of features included in the guidelines. Discusses the relation and integration of TEI mark-up and the HyTime standard. (CFR)

Maintains that one recurring theme in the Text Encoding Initiative (TEI) project has been the need to represent nonhierarchical information in a natural way. Proposes solutions to a variety of related problems. Contends that the examples presented can serve as a useful background for researchers using the TEI guidelines. (CFR)

Discusses concurrent, or parallel, programming languages; explains the design of the MultiLogo programming language; and describes a study of fourth and fifth graders that used MultiLogo to control robotic devices built out of Lego bricks. Three categories of MultiLogo programming bugs are described, and implications for changes in design and…

Presents a human-computer interaction (HCI) conceptions model designed to help in the understanding of the cognitive processes involved when college students learn to program computers. Examines syntactic and algorithmic HCI operational errors and reviews conceptions based on natural language reasoning, independent computer reasoning, and…

Compares and evaluates problems encountered when designing hypermedia applications for second-language instruction using Guide 3.1 and ToolBook 1.5. The strengths and limitations of both authoring facilities are discussed and domain-specific recommendations for the optimum delivery of pedagogically-sound practice are provided. (six references)…

Research advocating classroom use of the computer programming language LOGO is based on relatively long periods of instruction, plentiful provision of computers, and knowledgeable teachers. Recent research shows that LOGO may confuse children's understanding of angles. Considers implications for Scottish primary schools using LOGO as recommended…

Four experiments supported the hypothesis that, when learning to use equipment such as computers, if the material to be learned has an intrinsically high degree of interaction between elements, then learning might be facilitated by not having the equipment present. Thus, an analysis of intrinsic and extraneous cognitive load can lead to…
