the initial instruction set, Ss received a series of 100 word problems . The solutions of these problems were analyzed to determine the variables related to problem difficulty . A linear regression analysis ...
PEARLA NESHER THREE DETERMINANTS OF DIFFICULTY IN VERBAL ARITHMETIC PROBLEMS * A. INTRODUCTION A.1. The Research Problem The difficulty in teaching children how to solve verbal problems ...
to determine a word problem difficulty classification in children with arithmetic learning disabilities (ALD; n = 104) in comparison with typically achieving students (n = 44). We tested variables ...
. However, there are a number of studies that examine the effect that problem variables may have on the difficulty of word problems in arithmetic. A basic assumption of this approach is that the structure ...
rather than on empirically and theoretically justifiable variables that can predict item difficulty . In the current study, mathematical problem - solving items were designed for varying cognitive complexity ...
Values of 3J-couplings as obtained from NMR experiments on proteins cannot easily be used to determine protein structure due to the difficulty of accounting for the high sensitivity of intermediate ...
horizontal and inclined velocity structure model, in order to find a generic method for solving the multi-solution inverse problem of coal mine seismic source location. Specifically, the wavefront distribution ...
). The theory of publics used perceptual variables to explain communication behavior. However, it is interesting to determine whether a motivational effect is present in a problem - solving situation and to what ...
Abstract—Energy demand forecasting plays a key role in solving the majority of problems connected with determining the economic and energy development prospects. In view of high inertia and capital ...
. In this paper, we develop an efficient method without using PMLs to calculate resonant modes in biperiodic structures . We reduce the original eigenvalue problem to a small matrix nonlinear eigenvalue problem ...
