More than substitution: an ongoing journey of the 1:1 iPad program

The drive for the incorporation of digital technologies in the primary mathematics classroom is becoming more prevalent in our schools and curriculum documents. It is vital these technologies enrich the learning experience to make this integration worthwhile, and not simply be employed as a substitution for already satisfactory pedagogical approaches. The SAMR Model (Puentedura, 2006) incorporates four levels of technology integration in the classroom, from the simplicity of “Substitution” through to the transformative level of “Redefinition” (p. 7). In this paper, teachers from Ringwood North Primary School share how the SAMR Model impacted their teaching practice to support, enhance, and personalise student learning in mathematics through the 1:1 iPad Program. Tasks created with user-friendly and easily accessible digital resources such as Padlet, Kahoot! and Explain Everything are shared. Educators should consider the application and suitability of these digital technologies in conjunction with an appropriate level of integration prior to employment as a tool for enhancing mathematical understanding.

An approximate method for the solution of an influence function foil rolling model

Fleck and Johnson (Int. J. Mech. Sci. 29 (1987) 507) and Fleck et al. (Proc. Inst. Mech. Eng. 206 (1992) 119) have developed foil rolling models which allow for large deformations in the roll profile, including the possibility that the rolls flatten completely. However, these models require computationally expensive iterative solution techniques. A new approach to the approximate solution of the Fleck et al. (1992) Influence Function Model has been developed using both analytic and approximation techniques. The numerical difficulties arising from solving an integral equation in the flattened region have been reduced by applying an Inverse Hilbert Transform to get an analytic expression for the pressure. The method described in this paper is applicable to cases where there is or there is not a flat region.
