Measuring Creativity In The Fermi Problem, A Type Of Mathematical Modeling, Applying Information Theory, Hidemichi Okamoto
Journal of Educational Technology Development and Exchange (JETDE)
Many methods of measuring creativity have been studied - mainly in psychology. In recent years, there have been attempts to incorporate such creativity into mathematical modelling, a topic handled in mathematics education. Accordingly, some studies have been trying to assess creativity in it. However, there have been no clear criteria or formulas that can be used for any problem, since a rubric has been created for each problem and evaluated individually. In the present study, to measure creativity in the Fermi problem, a type of mathematical modelling, a formula that applies information theory used in information science is proposed and …

This exploratory study considered the literature on the history of manipulatives, with attention to tangrams, and examined the use of manipulatives in the elementary classroom through the Osmo Tangram. Specifically, manipulatives can be utilized in assisting elementary students to develop mathematical ability and achievement, with an emphasis on spatial sense. This paper describes design features of first generation virtual manipulatives, the amalgam of real and virtual manipulatives (e.g. Osmo Tangram), and results of an exploratory observational study of Osmo Tangram at the elementary level. Findings are discussed tailored to the future design and implementation of integrating tangram into mathematics instruction.
