This study examined the impact of e-book text-tracking design on 4th graders' (10-year-old children's) learning of Chinese characters. The e-books used in this study were created with Adobe Flash CS 5.5 and Action Script 3.0. This study was guided by two main questions: (1) Is there any difference in learning achievement (Chinese character…

Scope and Method of Study: The purpose of this study was to examine an instructional strategy intended to enhance engagement in the college classroom. The effects of the pause procedure on classroom engagement and cognitive load were studied. The relationships between levels of classroom engagement and near-term learning outcomes, as well as…

Background: The cognitive bases of language impairment in specific language impairment (SLI) and autism spectrum disorders (ASD) were investigated in a novel non-word comparison task which manipulated phonological short-term memory (PSTM) and speech perception, both implicated in poor non-word repetition. Aims: This study aimed to investigate the…

This study presents a mobile exploration activity that guides elementary students to learn during a social science activity with digital support from mobile devices and wireless communications. The students are situated in both the real world and the virtual world to extend their learning experiences. The learning activities between the field and…

The purpose of this study was to examine the effects of diagrams and time-compressed instruction on learning and learners' perceptions of cognitive load. The following design factors, visuals (visuals and non-visuals) and time-compressed instruction (0%-normal paced, 25, and 50%) were presented to 216 university students to analyze learning in a…

This dissertation presents several studies designed to probe the mental representations that physics experts and novices form when interacting with typical instructional materials, such as diagrams and problem statements. By using recognition tasks and a change detection task, the mental representations of experts and novices are studied in a more…

The current study investigated the effects of different external representational formats on learning combinatorics and probability theory in an inquiry based learning environment. Five conditions were compared in a pre-test post-test design: three conditions each using a single external representational format (Diagram, Arithmetic, or Text), and…

Within the cognitive load theory framework, we designed and compared three alternative instructional solution formats that can be derived from a common static hierarchical network representation depicting problem structure. The interactive-solution format permitted students to search in self-controlled manner for solution steps, static-solution…

Information Gathering is a knowledge construction process. Web learners make a plan for their Information Gathering task based on their prior knowledge. The plan is evolved with new information encountered and their mental model is constructed through continuously assimilating and accommodating new information gathered from different Web pages. In…

We investigated whether and how student performance on three types of spatial cognition tasks differs when worked with two-dimensional or stereoscopic representations. We recruited nineteen middle school students visiting a planetarium in a large Midwestern American city and analyzed their performance on a series of spatial cognition tasks in…

Contemporary debates on effective pedagogies for K-12 mathematics have called for shifts in the way teachers and teacher educators conceptualise mathematics as a subject and how it should be taught. This is reflected by changes in the curriculum including the inclusion of a strand called Working Mathematically within K-12 mathematics curriculum…

Our research objective focused on monitoring students' mental effort and cognitive achievement to unveil potential effects of an instructional change in an out-of-school laboratory offering gene technology modules. Altogether, 231 students (12th graders) attended our day-long hands-on module. Within a quasi-experimental design, a treatment group…

We propose that experience of emotion is a mental phenomenon, which requires resources. This hypothesis implies that a concurrent cognitive load diminishes the intensity of feeling since the 2 activities are competing for the same resources. Two sets of experiments tested this hypothesis. The first line of experiments (Experiments 1-4) examined…

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…

The impact of hypertext presentation formats on learner control and cognitive load was examined in this study using Campbell and Stanley's (1963) Posttest Only Control Group design. One hundred eighty-six undergraduate students were randomly assigned to read a web-based text with no annotations, online glossary annotations, embedded annotations,…
