Bouck, Emily C.; Long, Holly; Jakubow, Larissa – Investigations in Mathematics Learning, 2021
Research exists on mathematical interventions to support elementary students experiencing mathematical difficulties, yet little examines the provision of such interventions within an online learning environment. This study explored the online delivery of the virtual-representational-abstract (VRA) instructional sequence, taught via explicit…

Bouck, Emily C.; Chamberlain, Courtney; Park, Jiyoon – Education and Training in Autism and Developmental Disabilities, 2017
Manipulatives support students with and without disabilities in mathematics. However, as students age, concrete manipulatives can be limiting and potentially not age appropriate (Satsangi, 2015). An alternative is virtual manipulatives, including app-based manipulatives. This study compared the use of app-based manipulatives to concrete…

Peltenburg, Marjolijn; van den Heuvel-Panhuizen, Marja; Robitzsch, Alexander – Educational Studies in Mathematics, 2012
In this study, we examined special education students' use of indirect addition (subtraction by adding on) for solving two-digit subtraction problems. Fifty-six students (8- to 12-year-olds), with a mathematical level of end grade 2, participated in the study. They were given a computer-based test on subtraction with different types of problems.…

Peltenburg, Marjolijn; van den Heuvel-Panhuizen, Marja; Doig, Brian – British Journal of Educational Technology, 2009
This paper reports a study aimed at revealing special-educational-needs pupils' learning potential by means of an ICT-based assessment including a dynamic visual tool that might help pupils when solving mathematics problems. The study focused on subtraction problems up to 100, which require "borrowing". These problems, in which the value…

Moser, James M.; Carpenter, Thomas P. – 1982
This document reports on the initial phase of a project investigating how to relate formal mathematical representational and problem solving skills to informal strategies that children naturally invent to solve simple addition and subtraction problems. A program was developed that allows pupils to solve word problems on a microcomputer. A pilot…

Pagni, David, Ed. – 1991
The National Science Foundation funded Calculators and Mathematics Project, Los Angeles (CAMP-LA) developed curriculum materials focused solely on the use of calculators. The project was developed in three stages. The first stage studied the mathematics curriculums from different states and identified topics that are not included but should be if…
