This study assessed the efficacy of the spaced learning method compared to the activity-oriented method in improving chemistry achievement among high school students, focusing on different cognitive domains. An experimental design involving pre and post-test control groups was employed, with 106 students from two schools participating. The…

Two experimental studies were carried out to investigate whether adding multimedia features in a concept mapping task would improve the quality of the map built by students and promote more effective learning with expository hypertexts. Ninety-Nine undergraduates built a concept map to learn about a topic (water cycle or nitrogen cycle) either…

This study aims at comparing the effect of single- and dual-annotation modes, working memory (WM), and three tasks of different involvement loads (sentence writing, close deletion, and paragraph writing) on passive and active vocabulary development of proficient English as a foreign language (EFL) learners. While listening to an expository text,…

This study examines the effectiveness of pre-laboratory presentations in an undergraduate general chemistry laboratory using two different modes of delivery: a traditional lecture versus an in-class video presentation. It was anticipated that implementation of videos could result in improved laboratory efficiency, safety, and necessary technical…

The related constructs of opportunity to learn (OTL) and achievement growth are fundamental aspects of the current large-scale assessment and accountability system in operation in the United States. For purposes of this article, OTL is defined as the degree to which a teacher dedicates instructional time and content coverage to the intended…

This study investigated the influence of cognitive support for learning computer-based tasks using animated demonstration (AD) on instructional efficiency. Cognitive support included (1) segmentation and learner control introducing interactive devices that allow content sequencing through a navigational menu, and content pacing through stop and…

Digital games were reviewed as an emerging tool in educational technology. Factors such as instructional effectiveness, time on task, relationship to curricula, student socio-economic status, violence in games, and game mechanics were considered. Despite considerable variability among studies, larger overall effect sizes for the impact of games on…

A large body of research has shown that for novice learners, instruction that relies more heavily on worked examples than on problem solving, is more effective for learning as shown by higher test performance. Moreover, this beneficial effect is often obtained with less acquisition time and lower cognitive load during acquisition and test phase.…

The "interactivity principle" in multimedia learning states that giving learners control over pace and order of instructions decreases cognitive load and increases transfer performance. We tested this guideline by comparing a learner-paced instruction with a system-paced instruction. Time-on-task and interactive behavior were logged, and were also…

This study contributes to research investigating the effects of individual differences and online instructional design on learning. Learning performance was compared across three hypertext formats incorporating different navigational aids. The hierarchical map represented the physical structure of the hypertext in one condition, while the network…

The authors used a new multidimensional coding scheme to assess student learning engagement during 3 Grade 4 reading lessons. Students in 3 classes--2 in which students received integrated reading-science instruction and 1 in which they received traditional instruction--demonstrated moderate to high engagement in learning. However, students in the…

This study examined effects of orienting activities, processing opportunity, and varied lesson access times on college students' learning from interactive video. While practice remains dominant influence in effectiveness of interactive video, significant interactions were also found among access times, processing opportunity, and practice, and…

This research project was designed to explore ways of making computer text presentations more readable as a way of compensating for the constraints that computers impose on the display of text as compared with print-on-paper displays, e.g., limited screen resolution and display area. Forty-eight undergraduate teacher education majors enrolled in…

Using the cognitive fit paradigm as a theoretical framework, this study compared the problem-solving performance of users of a hypertext-based learning aid to the performance of users of a computer-based linear text learning aid. Subjects were 103 undergraduate MIS (Management Information Systems) majors enrolled in an information systems analysis…
