Science classes should support students' development of scientific argumentation. While previous studies have analyzed argumentative texts, they have overlooked the ways in which other types of representations, including images, affect the production of such texts. In addition, studies into the use of visual images in science education have…

Using meta-analysis, this study examines the effect of computer-supported education on students' attitudes and determines the degree to which the effect size obtained by combining the effect sizes of various studies differs, in terms of educational level, course subjects and application duration. Based on the inclusion criteria, a total of 32…

This paper employs meta-analysis to determine the influence of computer-based scaffolding characteristics and study and test score quality on cognitive outcomes in science, technology, engineering, and mathematics education at the secondary, college, graduate, and adult levels. Results indicate that (a) computer-based scaffolding positively…

The meta-analysis integrated findings from 51 independent evaluations of computer-based teaching in grades 6 through 12. Findings indicated that computer-based teaching raised students' final exam scores, improved student attitudes toward computers and toward their courses, and reduced the amount of time needed for learning.

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,…

Examines the world of integrated learning systems, focusing on research that explains their success and noting what needs to be done to make them more effective in elementary education. The article recommends creating a method to demonstrate their success or failure rate in improving scores on achievement tests. (SM)

Reviews several German computer assisted instruction (CAI) programs and describes an experiment in CAI to discover if immediate reinforcement in self-pacing would enable the students to perform better on the final examination. The experiment was carried out with two homogeneous sections of second-semester students of German in high school.…
