Confusion may benefit learning when it is resolved or partially resolved. Metacognitive strategies (MS) may help learners to resolve confusion when it occurs during learning and problem solving. This study examined the relationship between confusion and MS that students evoked in Betty's Brain, a computer-based learning-by-modelling environment…

Background: A multimedia software designed as a Computer-Assisted Scaffolding system was used to teach gas behavior on the submicroscopic level using Physics Education Technology Project (PhET) simulation. PhET is a set of interactive, research-based science and mathematics online simulations (https://phet. colorado.edu/). Purpose: The purpose was…

Supported electronic text (eText), or text that has been altered to increase access and provide support to learners, may promote comprehension of science content for students with disabilities. According to CAST, "Book Builder" (TM) uses supported eText to promote reading for meaning for all students. Although little research has been conducted in…

The main goal of this study was to explore whether the use of multimedia in genetics instruction contributes more to students' knowledge and comprehension than other instructional modes. We were also concerned with the influence of different instructional modes on the retention of knowledge and comprehension. In a quasi-experimental design, four…

The case-based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual…

Discusses the use of videodiscs to increase students' comprehension. Benefits of adding visual images to learning activities are discussed, videodiscs as sources of data for students to analyze are considered, and an example is given of using videodiscs to illustrate concepts in a chemistry class. (LRW)

It is well-documented that most students do not have adequate proficiencies in inquiry and metacognition, particularly at deeper levels of comprehension that require explanatory reasoning. The proficiencies are not routinely provided by teachers and normal tutors so it is worthwhile to turn to computer-based learning environments. This article…

Discussion of how visual analogies aid students' understanding of math and science focuses on new types of representations that use computers. Topics addressed include understanding and cognitive performance; the role of representations in understanding, including examples; evidence of instructional effectiveness of new representations; and…

Reports on a study that examined and compared the cognitive effectiveness of a traditional hands-on laboratory exercise with a computer-simulated program on the same topic. Sought to determine if coupling these formats would provide optimum student comprehension. Suggests hands-on exercises be followed by computer simulations as postlaboratory…
