The role of definition in students' understanding with particular reference to the concavity of a function
(2006)
In this study, the effect of different definitions of concavity on students' understanding was investigated. Students enrolled in the calculus-II course in the science and engineering faculties in Anadolu University, Turkey ...
Linear Functions and Slope: How Do Students Understand These Concepts and How Does Reasoning Support Their Understanding?
(Fac Teacher Education, 2018)
The aim of this study was to investigate eighth grade students' conceptual understanding and types of reasoning about linear functions and slope. This is a mixed method study. Quantitative data were collected with algebra ...
Tight span of subsets of the plane with the maximum metric
(Academic Press Inc Elsevier Science, 2016)
We prove that a nonempty closed and geodesically convex subset of the l(infinity) plane R-infinity(2) is hyperconvex and we characterize the tight spans of arbitrary subsets of R-infinity(2) via this property: Given any ...
Modules Whose Direct Summands Are Fi-Extending
(Springer, 2017)
A module M is called FI-extending if every fully invariant submodule of M is essential in a direct summand of M. It is not known whether a direct summand of an FI-extending module is also FI-extending. In this study, it ...
On constructing total orders and solving vector optimization problems with total orders
(Springer, 2011)
In this paper, we introduce a construction method of total ordering cone on R(n). It is shown that any total ordering cone on Rn is isomorphic to the cone R(lex)(n). Existence of a total ordering cone that contain given ...
Development of a three dimensional geometric thinking test for early graders
(Sriwijaya University, 2018)
This study aimed to develop a three-dimensional geometric thinking test to determine the geometric thinking of early graders in the paper-pencil environment. First, we determined the components of three-dimensional geometric ...
A Fictitious Play Algorithm for Matrix Games with Fuzzy Payoffs
(Hindawi LTD, 2012)
Fuzzy matrix games, specifically two-person zero-sum games with fuzzy payoffs, are considered. In view of the parametric fuzzy max order relation, a fictitious play algorithm for finding the value of the game is presented. ...
The snowflake curve as an attractor of an iterated function system
(2013)
Although the snowflake curve, the boundary of the Koch snowflake, is one of the well-known fractals, there is no iterated function system (IFS) for it in the literature. In this study, we give an IFS for this familiar closed curve
Three different methods for numerical solution of the EW equation
(Elsevier Sci LTD, 2008)
Numerical solutions of the equal width wave (EW) equation are obtained by using a Galerkin method with quartic B-spline finite elements, a differential quadrature method with cosine expansion basis and a meshless method ...
Convex extensions of the convex set valued maps
(Academic Press Inc Elsevier Science, 2006)
In this article the existence of the convex extension of convex set valued map is considered. Conditions are obtained, based on the notion of the derivative of set valued maps, which guarantee the existence of convex ...
