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…

The purpose of the present meta-analysis is to the investigate the overall effectiveness of L2 vocabulary instruction and to find the moderator variables affecting its effectiveness. By defining a rigorous inclusion and exclusion criteria, a total number of 16 primary studies (N = 1008), 7 published and 9 Ph.D. dissertations, were included. Under…

This meta-analysis synthesizes research findings on the effects of computer-supported collaborative learning (CSCL) based on its three main elements: (1) the collaboration per se, (2) the use of computers, and (3) the use of extra learning environments or tools, or supporting strategies in CSCL. In this analysis, 425 empirical studies published…

This paper is a systematic review of research investigating help options in the different language skills in computer-assisted language learning (CALL). In this review, emerging themes along with is-sues affecting help option research are identified and discussed. We argue that help options in CALL are application resources that do not only seem…

This paper explores whether the principles of cognitive load and multimedia theory are mediated by cognitive style, gender, and prior knowledge. Participants were 91 children aged 10-11 years (54 boys, 37 girls), each assigned to one of two presentation modes. In Condition 1 children were presented with diagrams supported by printed textual…

Reviews current empirical data on the effectiveness of animation in computer-based instruction. Research on static visuals and learning is examined; animation research is described that includes studies with elementary school children, high school students, and adult learners; and implications for current instructional design are suggested. (56…

This article reviews the literature on the use of content enhancement techniques to help secondary students with learning disabilities to identify, organize, comprehend, and memorize critical content information. Content enhancements described include visual displays, mnemonics, advance organizers, study guides, peer mediation, audiotapes, and…

Computer-based instruction (CBI) has undergone tremendous changes in the past decade. This paper focuses on the following three areas of designing information presentation: (1) screen design literature is dated, and the existing guidelines do not allow for advances in computer technology; (2) open-ended guidelines may offer designers sufficient…

A review of the literature and current technology focuses on the determination of what strategies and methods are appropriate for computer-assisted language learning (CALL). A brief overview is presented regarding the historical development and non-use (to its full potential) of the computer in the education field, and particularly in the area of…

Discussion of computer-based instruction and animation focuses on a study of undergraduates that investigated the effects of two computer-based instructional strategies, visual display and feedback type, on teaching how to troubleshoot electronic circuits. Time spent on various components of the program is also examined. (35 references) (LRW)

Discussion of teaching literature through multimedia argues that simpler techniques explaining visual symbols such as illustrations, annotation of texts with commentaries, explanations, word meanings, and maps are not sufficient for conveying the message in culturally displaced (i.e., foreign language) texts. (18 references) (EA)

Reviews theories of anchored instruction and addresses issues related to learning, transfer, and assessment. Highlights include video-based macrocontexts; videodisc anchors versus computer-based simulations; cooperative learning; transfer outside the classroom; authenticity; visual anchors versus verbal anchors; situated cognition; and using…

Reviews education research on general design principles and concepts, including perception/communications theories and learning principles. Media research is also reviewed. Based on this past research, a model is proposed for the design of video displays in an interactive videodisc (IVD) instructional program. (AEF)

This collection of papers examines research methods in geographical education in nine countries. "Research Methods in the History of Geographical Education" (William Marsden, the United Kingdom) examines the methods used and some of the research undertaken in the history of geographical education. "Research Methods in Investigating…
