LOOKING WITHOUT SEEING: THE ROLE OF METACOGNITIVE BLINDNESS OF STUDENT WITH HIGH MATH ANXIETY
International Journal of Cognitive Research in Science, Engineering and Education, 2019 This study aims to reveal how metacognitive failure occurs during problem-solving experienced by the pre-service teacher with mathematics anxiety. The data collected are in the form of words obtained through interviews, pictures of the results of the ...

Corona product of signed graphs and its application to signed network modelling [PDF]
arXiv, 2019 The notion of corona of two graphs was introduced by Frucht and Harary in 1970. In this paper we generalize their definition of corona product of two graphs and introduce corona product of two signed graphs by utilizing the framework of marked graphs, which was introduced by Beineke and Harary in 1978. We study the structural and spectral properties of

Advanced Functional Materials, EarlyView.This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.

Lectures mathématiques : sédimentation, réactivation ou partage ?
Methodos, 2020 Historians of mathematics have often noticed a singularity of their discipline: unlike physics, the history of mathematics does not proceed essentially by conjectures and refutations, but by a succession of reinterpretations of the past in order to ...

Almost strictly sign regular rectangular matrices [PDF]
Journal of Computational and Applied Mathematics 404 (2022) 113121Almost strictly sign regular matrices are sign regular matrices with a special zero pattern and whose nontrivial minors are nonzero. In this paper we provide several properties of almost strictly sign regular rectangular matrices and analyze their QR factorization.

Toward a Semiotic Framework for Using Technology in Mathematics Education: The Case of Learning 3D Geometry [PDF]
, 2004 This paper proposes and examines a semiotic framework to inform the use of technology in mathematics education. Semiotics asserts that all cognition is irreducibly triadic, of the nature of a sign, fallible, and thoroughly immersed in a continuing ...

Chasing Charge Carriers: Diffusion Dynamics in Mixed‐n Quasi‐2D Colloidal MAPbBr3 Perovskites
Advanced Functional Materials, EarlyView.Metal halide perovskites are noted for their tunable optical properties. Colloidal synthesis allows the formation of differently shaped perovskite nanocrystals with varying optical and carrier transport behavior. Three MAPbBr3 morphologies are characterized: nanoplatelets, nanosheets, and nanostripes.

Understanding the meaning of the equal sign : an investigation of elementary students and teachers. [PDF]
, 2015 The purpose of this study was to investigate the impact of two different policies for implementing new mathematics standards in two schools, for grades two through five, on student understanding of the equal sign.
