Our objective in this study was to investigate how the eye-movement behavior and concurrent verbal protocols of students with high-/low-prior-knowledge were reflected in the use of multiple representations for scientific argumentation. We also examined the degree of consistency between eye-fixation data and verbalization to ascertain how and when…

Based on cognitive load theory, the effect of different levels of instructional detail and expertise in a simulation-based environment on learning about concepts of correlation was investigated. Separate versions of the learning environment were designed for the four experimental conditions which differed only with regard to the levels of written…

The ability to flexibly allocate attention to goal-relevant information is pivotal for the completion of high-level cognitive processes. For instance, in comprehending illustrated texts, the reader permanently has to switch the attentional focus between the text and the corresponding picture in order to extract relevant information from both…

With applications of Tree of Life data becoming ever more prevalent in everyday contexts, tree thinking has emerged as a vital component of scientific literacy. This article reports a study testing the hypothesis that instruction in natural selection, which is the primary focus of US evolution education at the high school and introductory college…

Cognitive science principles should have implications for the design of effective learning environments. The self-explanation principle was chosen for the current work because it has developed significantly over the last 20 years. Early formulations hypothesized that self-explanation facilitated inference generation to supply missing information…

This study investigates children's metarepresentational competence (MRC) with regard to listening to and making sense of simple sonic stimuli. Using diSessa's (2002) seminal work on MRC in mathematics and sciences as background, it aims to assess the relative importance children attribute to several criteria for representational adequacy…

The purpose of the two experiments was to investigate the potential effects of different types of visualizations and self-explanation prompts on learning human cardiovascular system in a multimedia environment. In Experiments 1 and 2, 70 and 44 college students were randomly assigned to one of the four conditions in a 2 × 2 factorial design with…

This paper has five objectives: (a) to review the scientific background of, and major findings reported in, Medical Problem Solving, now widely recognized as a classic in the field; (b) to compare these results with some of the findings in a recent best-selling collection of case studies; (c) to summarize criticisms of the hypothesis-testing model…

Student teachers learned about teaching principles with the help of an instructional program that included classroom animation exemplars, where expert teachers demonstrate how to apply teaching principles to a classroom scenario. Some students learned by solely observing the classroom animations, whereas others were presented with the expert's…

This research examined the impact of formative quizzes on e-learning designed to teach volunteers how to tutor struggling readers. Three research questions were addressed: (1) Do embedded quizzes facilitate learning of e-content? (2) Does the announcement of upcoming quizzes affect learning? (3) Does prior knowledge interact with quizzing and…

The efficient reader constructs tentative hypotheses about the meaning of the text that has been read and about the content yet to come. The hypotheses remain tentative until all related information has been accounted for. The reader then constructs a model that considers all of the details in a text. If a promising interpretation fails to account…

Mayer's SOI theory suggests that supplements added to designed environments can promote learners' knowledge construction and that different types of supplements will serve different purposes in knowledge construction. Some adjuncts can facilitate selection. Other adjuncts, such as diagrams, might facilitate the organization of important…

Using computer controlled text presentation that permitted the measurement of reading time for individual sentences, a study tested two hypotheses concerning how schemata guide reading comprehension. The focusing hypothesis suggested that the schemata activated by the reader's perspective might identify relevant information to which additional…

The effects of mobilizing prior knowledge on information processing were studied. Two hypotheses, the cognitive set-point hypothesis and the selective attention hypothesis, try to account for the facilitation effects of prior knowledge activation. These hypotheses predict different recall patterns as a result of mobilizing prior knowledge. In…

Two hypotheses, the cognitive capacity hypothesis and the selective attention hypothesis, try to account for the facilitation effects of prior knowledge activation. They appear to be mutually exclusive since they predict different recall patterns as a result of prior knowledge activation. This study was designed to determine whether the two…
