Iversen, Kjaerand; Nilsson, Per – International Journal of Computers for Mathematical Learning, 2007
This paper focuses on the different ways in which students in lower secondary school (14-16 year olds) experience compound random events, presented to them in the form of combined junctions. A carefully designed ICT environment was developed enabling the students to interact with different representations of such structures. Data for the analysis…

Claus, Berry; Kelter, Stephanie – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2006
This study investigated the representations that readers construct for narratives describing a sequence of events. Participants read narratives describing 4 successive events in chronological order (Event 1, Event 2, Event 3, Event 4 [E1, E2, E3, E4] Experiment 1) or in nonchronological order with E1 being mentioned in a flashback (E2, E3, E1,…

Moss, Jarrod; Kotovsky, Kenneth; Cagan, Jonathan – Cognitive Science, 2006
As engineers gain experience and become experts in their domain, the structure and content of their knowledge changes. Two studies are presented that examine differences in knowledge representation among freshman and senior engineering students. The first study examines recall of mechanical devices and chunking of components, and the second…

Knierim, James J. – Learning & Memory, 2006
Place cells of the rat hippocampus are a dominant model system for understanding the role of the hippocampus in learning and memory at the level of single-unit and neural ensemble responses. A complete understanding of the information processing and computations performed by the hippocampus requires detailed knowledge about the properties of the…

Cronje, J. C.; Fouche, J. – Computers & Education, 2008
While different approaches to evaluation will yield different results, depending on the purpose of the evaluation this article describes an evaluation approach that was aimed at investigation of the mental models of users of the programme. The study was driven by questions about the differences in mental models of the instructional designers and…

Passerini, Katia – Journal of Educational Multimedia and Hypermedia, 2007
Understanding the impact of different technological media on the achievement of instructional goals enables the delivery of a subject matter more effectively. Among the various instructional technologies that advance learning, educators and practitioners recurrently identify interactive multimedia as a very powerful tool for instruction and…

Boatman, Dana F. – Clinical Linguistics & Phonetics, 2007
Recent brain mapping studies have provided new insights into the cortical systems that mediate human speech perception. Electrocortical stimulation mapping (ESM) is a brain mapping method that is used clinically to localize cortical functions in neurosurgical patients. Recent ESM studies have yielded new insights into the cortical systems that…

Schar, Sissel Guttormsen; Zimmermann, Philippe G. – Journal of Research on Technology in Education, 2007
This paper covers an experiment designed to investigate the relationship between the didactical setting and learning effects with animations. We investigated whether the cognitive load imposed by animations could be reduced when the students could control the flow of the animation. We did not find an effect due to the fact that the students did…

Shute, Valerie J. – 1994
For an intelligent tutoring system (ITS) to earn its "I", it must be able to (1) accurately diagnose students' knowledge structures, skills, and/or learning styles using principles, rather than pre-programmed responses, to decide what to do next; and (2) adapt instruction accordingly. While some maintain that remediation actually…

Beacom, Matthew – 2000
This paper discusses the following four changes in how we use sources of information or representations of knowledge: (1) from tangible to intangible media--how sources of information and representations of knowledge are manifested or packaged on the Internet; (2) from books and journals to services and databases--how such knowledge packages are…

Roth, Wolff-Michael; McGinn, Michelle K. – Science Education, 1997
Presents an alternative perspective that conceives of graphing as observable practices employed to achieve specific goals rather than as knowledge represented in students' minds. Highlights the nature of graphs as semiotic objects, rhetorical devices, and conscription devices. Illustrates the plausibility and fruitfulness of the new perspective in…

Noordman, Leo G. M.; Vonk, Wietske – Discourse Processes, 1998
Focuses on the role of cognitive structures in the reader's knowledge. Argues that causality is an important category in structuring human knowledge and that this property has consequences for text processing. Discusses research illustrating that the more the information in the text reflects causal categories, the more easily the information is…

Petry, Frederick E.; Cobb, Maria A. – Journal of the American Society for Information Science, 1998
Presents a model for representing and storing binary topological and directional relationships between 2-dimensional objects that is used to provide a basis for fuzzy querying capabilities. A data structure called an abstract spatial graph (ASG) is defined for the binary relationships that maintains all necessary information regarding topology and…

Wheeler, Alan E. – Science Education International, 1997
Argues for the use of the archaeological metaphor as an apt one when examining the historical layers and foundational bases underlying much of the current thought and practice in science education. Suggests some sort of correspondence between archaeological and science education processes. (DDR)
