Four- and 5-year-olds' understanding of basic turtle graphics commands was examined before and after a hands-on, interactive problem-solving experience. Children (n=32) saw display screen events consisting of an initial turtle state, a command transformation, and the resulting turtle state. They were asked to give the command executed in each…

The purpose of this paper was to investigate the effects of different types of visual illustrations on learner's learning interest, motivation and achievement, especially in multimedia learning. The participants were drawn from two classes of an "Introduction to Educational Technology" course and randomly assigned to one of the three…

Adjunct questions were inserted after each of 12 computer-animated graphics sequences shown to 160 eighth-grade science students. These sequences presented two relationships in a purely spatial fashion. Four randomly assigned treatment groups received questions targeting one of the two relationships (temperature or molecular motion) over all or…

Students' reactions and performances were examined when taught engineering geometry concepts using a standard microcomputer-aided drafting software package. Two sample groups were compared based on their computer experience. Included are the methodology, data analysis, and conclusions. (KR)

Discusses production and evaluation of interactive computer-assisted videodisc laboratory tutorial simulations for use in prelaboratory instruction and as laboratory experiment replacement in an undergraduate chemistry course. Student performance on laboratory reports and tests was significantly better for students who utilized the simulations.…

Presents a rationale for future research relating to educational computing, discusses beneficial studies that have been undertaken, and outlines specific areas where further research is needed, including studies on achievement, retention, and transfer measurement; material characteristics which enhance achievement; implementation variables,…
