The cognitive load and learning effects of dual-code and interactivity--two multimedia methods intended to promote meaningful learning--were examined. In Experiment 1, college students learned about the causal chain of events leading to the process of lightning formation with a set of words and corresponding pictures (Group WP), pictures (Group…

New technologies allow the display of text, static visuals, and animations. Although animations are inherently attractive, they are not always beneficial for learning. Problems may arise especially when animations modify the learner's cognitive load in an unintended way. In two learning experiments with 40 and 26 university students, the effects…

Students participated in a study (n = 98) investigating the effectiveness of three types of annotations on three learning outcome measures. The annotations were designed to support the cognitive processes in the comprehension of scientific texts, with a function to aid either the process of selecting relevant information, organizing the…

Cognitive load theory (CLT) has been successful in identifying instructional formats that are more effective and efficient than conventional problem solving in the initial, novice phase of skill acquisition. However, recent findings regarding the "expertise reversal effect" have begun to stimulate cognitive load theorists to broaden their horizon…

In this article we suggest a method of evaluating learner expertise based on assessment of the content of working memory and the extent to which cognitive load has been reduced by knowledge retrieved from long-term memory. The method was tested in an experiment with an elementary algebra tutor using a yoked control design. In the learner-adapted…

The purpose of this article is to review and critique each of the research studies published in this special issue. We will critique each article, derive one or more instructional design heuristics based on the findings for each study, and provide recommendations for extending particular lines of research. Three suggestions are provided concerning…

During the past decade, design-based research has demonstrated its potential as a methodology suitable to both research and design of technology-enhanced learning environments (TELEs). In this paper, we define and identify characteristics of design-based research, describe the importance of design-based research for the development of TELEs,…

Although the conditions for successful technology integration finally appear to be in place, including ready access to technology, increased training for teachers, and a favorable policy environment, high-level technology use is still surprisingly low. This suggests that additional barriers, specifically related to teachers' pedagogical beliefs,…

Rooted in behavioral theory, particularly the radical or selectivist behaviorism of B.F. Skinner (1953, 1954, 1966, 1968, 1974), the direct instruction (DI) approach to teaching is now well into its third decade of influencing curriculum, instruction, and research. It is also in its third decade of controversy. Our purpose is to present the DI…

Teachers often learn technology skills and integration strategies in intensive seminars, ineffective means for professional learning because experiences are seldom transferred to instructional practices. Thus, effective technology integration requires teachers to obtain learning experiences within the context of their teaching so they can…

Learning object technology is viewed as a method for fast retrieval. This effort is on developing unique schemas for a targeted group to aid efficient retrieval. In this article, I study a user-centric model for developing tags for K-12 educators that is based on user needs, expectations, and problems. I use a combination of techniques from human…

The relationships among the frequency of access to online lecture notes, examination performance, and class attendance were investigated. Data on use of online notes were gathered from the log maintained by the server and from student responses to a questionnaire. Students who made any attempt to access online notes viewed notes associated with…

The main purpose of this study was to determine if online computer-based math problem-solving and paper-and-pencil math problem-solving tests are suitable tools for measuring math problem-solving, by comparing student performance on traditional style paper-based tests to performance on the same tests online. Data collection for this study was…

We present a new highly interactive computer animation tool to increase the mathematical skills of deaf children. We aim at increasing the effectiveness of (hearing) parents in teaching arithmetic to their deaf children, and the opportunity of deaf children to learn arithmetic via interactive media. Using state-of-the-art computer animation…

This study examined the effects of contiguity and feature animation on the recall, map reconstruction, inference performance, and en-route behavior of university students studying a computer-delivered reference map with associated text. Participants were randomly assigned to six versions of a computer program created by crossing three contiguity…
