The Cognitive and Affective Dimensions of Mathematical Difficulties in Schoolchildren
… and Elkins, 1999) suggests that children with mathematical difficulties (MD) use inefficient problem solving strategies and lack computational fluency. This thesis extends existing research by investigating the cognitive and affective dimensions of mathematical difficulties in schoolchildren …

Gravity Induced Stresses in a Shrink-Fit Disk.
… techniques. This, of course, is due to mathematical difficulties associated with the solution of the governing equations subject to prescribed boundary conditions. Several techniques of an approximate nature have been developed for the treatment of more complex problems, among them being …

Calculation of the flow over a stalled airfoil
… and inviscid regions, thus eliminating the mathematical difficulties usually associated with separation. A distributed source on the upper surface of the airfoil provides an outflow to simulate the displaced boundary, and a distributed sink downstream of the trailing edge closes the wake. …

Raising Teacher Sensitivity to Key Numeracy Competencies in the Early Years
Mathematical competence is a key capability for success in adult life, and yet many students do not achieve functional levels of numeracy during their school lives. Furthermore, many teachers report that they lack the confidence in teaching mathematics that they have for teaching literacy. Research …

Numeracy support for year two students
… who were considered to be at risk of developing mathematical difficulties. The program comprised of two 85 minute lessons and one 40 minute lesson per week in a room adjacent to the Year Two classroom. A social constructivist method of teaching was put into practice within the structure of a …

Improving Students’ Mathematical Understanding by Engaging with the Mathematical Structure
… teaching using the underlying structure of mathematical concepts improves students’ understanding. This case focused on fractional magnitudes. For this study, instantiations are defined as mathematical concepts considered from the viewpoint of the learner. Mathematical structure consists of …

Parallel algorithms for three dimensional electrical impedance tomography
… of the volume. The focus of the thesis is the mathematical and numerical aspects of reconstructing the impedance image from the measured data (the reconstruction problem). The reconstruction problem is mathematically difficult and most reconstruction algorithms are computationally intensive. …

Space-Charge Saturation and Current Limits in Cylindrical Drift Tubes and Planar Sheaths
… the space-charge limited current. Because of the mathematical difficulties, this limit is typically estimated from a one-dimensional theory. This work presents a two-dimensional theory for calculating an upper-bound for the space-charge limited current of relativistic electron beams propagating in …

Some Problems Concerning the Generalized Hyperbolic and Related Distributions
… number of terms. Consequently, computational and mathematical difficulties which are due to Kλ (z) can be dealt with in a much simpler manner replacing the special function by a finite series. For completeness, a reliable routine to approximate the function when z is small was also implemented. …
