This study investigated the performance and reasoning of 143 Australian students who completed mathematics tasks sourced from their national test. Specifically, this study examined changed student performance and reasoning on items where the graphic component was modified. The results of the study revealed significant performance differences…

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…

Research has demonstrated that instruction that relies heavily on studying worked examples is more effective for less experienced learners compared to instruction emphasizing problem solving. However, the guidance associated with studying some worked examples may reduce the performance of more experienced learners. This study investigated…

Currently there is an increasing trend to implement functionalities that allow for the development of applications based on Cloud computing. In education there are high expectations for Learning Management Systems since they can be powerful tools to foster more effective collaboration within a virtual classroom. Tools can also be integrated with…

This study investigated the effects of segmented animated graphics utilized to facilitate learning of electrolysis of aqueous solution. A total of 171 Secondary Four chemistry students with two different spatial ability levels were randomly assigned to one of the experimental conditions: (a) text with multiple static graphics (MSG), (b) text with…

Animation has an inherent advantage over static graphics when presenting dynamic content because it provides a more accurate and realistic depiction. Simultaneously, animation has an inherent disadvantage because most animated information is perceptually transient. In this quasi-experimental study, cognitive load theory was used to investigate the…

This study explored the effectiveness of external representations presented together with compare word problems, and whether such effectiveness was moderated by working memory. Participants were 49 secondary school students. Each participant solved 48 problems presented in 4 presentation types that included 2 difficulty treatments (number of steps…

An investigation was carried out to examine the effects of cognitive style on learners' performance and interaction during complex problem solving with a computer modeling tool. One hundred and nineteen undergraduates volunteered to participate in the study. Participants were first administered a test, and based on their test scores they were…

The present article examines how suitable expository films are for learning. This question was motivated by the assumption that films are processed in a superficial manner. However, previous research has been dominated by the analyses of outcome measures and has never taken a look at online measures so that no clear conclusions have been drawn.…

Previous cognitive models of memory have not comprehensively taken into account the internal cognitive load of chunking isolated information and have emphasized the external cognitive load of visual presentation only. Under the Virk Long Term Working Memory Multimedia Model of cognitive load, drawing from the Cowan model, students presented with…

This study investigated the effects of example-postings on students' cognitive load and performance in online discussions. Cognitive overload was assumed had caused the problem of the lack of reflective and thoughtful contributions in student discussions. The theoretical foundation supporting the use of example-postings aiming at reduce…

In this study, I examine the instruction of four preservice English teachers (PSTs) for cognitively demanding literature-based writing tasks in order to investigate the types of tasks that PSTs identify as cognitively demanding, how PSTs' instruction for such tasks maintains or degrades the task's intellectual rigor, and possible…

The effects of instructional fading using completion problems on student performance were investigated in this study. Instructional fading is the gradual withdrawal of the amount of assistance provided to the student and was accomplished in this study using completion problems. They were used to gradually transition the student from completely…

In recent years there has been a growing interest in the role of attention in the processing of social stimuli in individuals with autism spectrum disorders (ASD). Research has demonstrated that, for typical adults, faces have a special status in attention and are processed in an automatic and mandatory fashion even when participants attempt to…

Using the cognitive theory of multimedia learning, this study aimed to evaluate the design of one multimedia courseware used for teaching English as a foreign language (EFL) in China and to compare the attitudinal differences in the teachers' and students' evaluation of the courseware. A questionnaire was developed and validated. Results indicated…
