A STUDY OF PRESERVICE TEACHERS’ MENTAL COMPUTATION ATTITUDES, KNOWLEDGE, AND FLEXIBILITY IN THINKING FOR TEACHING MATHEMATICS
… attitudes and beliefs towards mathematics, mental and written computations, and mental computation anxiety, to investigate their use of different mental computation strategies using different approaches (i.e., Direct Teaching (DT) and Open-Approach (OA)) among the three different groups, and …

Snapshots of the St. Lucian market place: computational strategies of another culture
… in St. Lucia, West Indies, examined the mental computational strategies used by adult vendors (in the market, on the street, on the beach) and nonvendors. The daily activities of a vendor involve a substantial amount of mental calculation when engaging in financial transactions, in which …

Estimational Abilities and Mathematics Achievement of Seventh Graders
<p>Computational estimation and mental computation are two of the most neglected areas of today's mathematical curriculum. Much has been written about these two concepts, but little instruction has been carried out in the classroom (Johnson, 1979; Reys, 1986). Freeman (cited in Reys & Bestgen, …

Desarrollo del pensamiento relacional y comprensión del signo por alumnos de tercero de educación primaria
… structural sense, symbolic sense, flexible computation strategies, mental computation, conceptual meta-strategies and quasivariable thinking. We deepen on the meaning of the terms equality, equivalence and identity, the origin and historical evolution of the equal sign and the various …

Dynamic physical affordances for shape-changing and deformable user interfaces
… cognition by allowing users to offload mental computation spatially. However, devices today include more and more functionality, with increasingly fewer physical affordances, losing many of the advantages in expressivity and dexterity that our hands can provide. My research examines how …

Low complexity system architecture design for medical Cyber-Physical-Human Systems (CPHS)
… and safety in these highly interactive computations is challenging. In particular, the interaction between these three components needs to be coordinated collectively in order to conduct safe and effective operations. The interaction nevertheless increases by orders of magnitude the …
