1 Improving School Children’s Mathematical Word Problem Solving Skills through Computer-Based Multiple Representations

Instructional resources that employ multiple representations have become commonplace in mathematics classrooms. This study will present computer software, LaborScale which was designed to improve seventh grade students ’ word problem-solving skills through computer-based multiple representations including graphic, symbolic, and audio representations. The proposed presentation will illustrate the design, implementation and validation of an interactive learning environment (ILE), LaborScale. This ILE is based upon the principles of computer based interactive problem solving environments, which connects different types of knowledge representation forms, and aims primarily to assist students as they explore symbolic representations used in word-problem solving process. Problem Solving When solving problems, a learner combines previously learned elements of knowledge, rules, techniques, skills, and concepts to provide a solution to a novel situation. It is generally accepted that mathematics is both process and product: both an organized body of knowledge and a creative activity in which the learner participates. It might, in fact, be claimed that the real purpose of learning rules, techniques, and content is to enable the learner to do mathematics, indeed to solve problems (Orton, 1987). Thus proble
