ABSTRACT<br />
This study developed a computer-assisted mathematical problem-solving system in the form of a network<br />
instruction website to help low-achieving second- and third-graders in mathematics with word-based addition<br />
and subtraction questions in Taiwan. According to Polya’s problem-solving model, the system is designed to<br />
guide these low-achievers through the parts of the problem-solving process that they often ignore. The<br />
situations of verbal questions are visualised to walk the students through the course of thinking so they can<br />
solve the question with proper understanding of its meaning. We found that the mathematical problemsolving<br />
ability of experiment group students was significantly superior to that of control group students.<br />
Most of the participants were able to continue the practice of solving word-based mathematical questions,<br />
and their willingness to use the system was high. This indicates that the computer-assisted mathematical<br />
problem solving system can serve effectively as a tool for teachers engaged in remedial education.<br />

Introduction<br />
In traditional teaching, assessment of whether students had understood a mathematical problem was based on<br />
whether they could describe the correct arithmetic procedure. However, it was not enough to evaluate students’<br />
mathematics concepts and abilities of solving math problems merely depending on their writing. Some oral<br />
interpretation and explanation should be considered from multiple assessment points of view (Hwang, Chen &<br />
Hsu. 2006). Several researches also pointed out that good problem solving skills are the key to acquiring a<br />
successful solution in learning mathematics (Gagne, 1985; Mayer, 1992). The cognitive thinking process, as well<br />
as abstract mathematical concepts and representations, is often extremely difficult for middle-school and<br />
elementary students. Many efforts have been made to explore alternative ways of teaching mathematics by<br />
creating curricula and didactic material incorporating new tools, pedagogical approaches, and models or methods,<br />
to engage learners in a more pleasant mathematical learning process (Szendrei, 1996).<br />
Fleischner and Marzola (1988) indicated that the mathematics learning achievement of about 6% of all middleschool<br />
and elementary students were severely flawed. In one of Polya’s speeches (1962), he expounded on<br />
learning, teaching and learning to teach. He stated the fact that only 1% of the students would need to study<br />
mathematics, 29% would need to use mathematics in the future, and 70% would never need knowledge of<br />
mathematics beyond the elementary level in their daily life (Mayer, 1992). Obviously, if a student could<br />
successfully solve a math problem by arithmetic calculation, that did not mean the student really understood it.,<br />
Many students and teachers have found the learning and teaching of solving verbal questions to be the most<br />
challenging part of mathematics education (De Corte & Verschaffel, 1993). Cardelle-Flawar (1992) discovered<br />
that, in order to help these low-achievers sharpen their problem-solving skills; their verbal ability must be<br />
improved first to enable them to identify the core of the problem.<br />
Problem-Based Learning (PBL)<br />
Problem-based learning (PBL) is considered to be one of the most appropriate solutions to increase students’<br />
learning motivation and to develop practical skills. It is a student-centered instructional strategy, and<br />
students can solve problems collaboratively and reflect on their experiences. It also can help students<br />
develop skills and acquire knowledge (Bruer, 1993; Williams, 1993). Polya’s Mathematics Problem-Solving<br />
