We examined short-term changes in children’s numerical estimation, the representational changes that gave rise to improved estimates, and the hypothesis that experiences that highlight discrepancies between logarithmic and linear representations of numerical magnitude result in the greatest changes in estimation accuracy.

Both metacognitive and associative models have been proposed to account for children’s strategy discovery and use. Models based on only metacognitive or only associative mechanisms cannot entirely account for the observed mix of variability and constraint revealed by recent microgenetic studies of children’s strategy change. We propose a new approach where metacognitive and associative mechanis...

Several methods for ontology development have been proposed. However, the development of domain ontologies is still carried out in an ad-hoc manner. This paper explores the use of a microgenetic algorithm with a seeding scheme based on hierarchical clustering for ontology class hierarchy construction. The microgenetic algorithm (μGA) is composed of an inner loop and an outer loop. The inner loo...

This document contains the following full and short papers on cognition and conceptual change from ICCE/ICCAI 2000 (International Conference on Computers in Education/International Conference on Computer-Assisted Instruction): (1) "A Method of Creating Counterexamples by Using Error-Based Simulation" (Tomoya Horiguchi and Tsukasa Hirashima); (2) "An Interactive Game System To Stimulate Word Ass...

One of the main limitations of utilizing optimal wavefront shaping in imaging and authentication applications is the slow speed of the optimization algorithms currently being used. To address this problem we develop a microgenetic optimization algorithm (μGA) for optimal wavefront shaping. We test the abilities of the μGA and make comparisons to previous algorithms (iterative and simple-genetic...

summary writing is associated with lots of cognitive and metacognitive complexities that necessitates instruction (hirvela & du, 2013). contrary to majority of studies carried out on summarization instruction, the present study addressed the underlying processes or microgenetic developments of the iranian efl learners’ summary writing. to this end, 41 male and female undergraduate students ...
