A Study of Problem-Solving Strategies and Errors in Inequalities for Junior High School Students
The aim of this study is to investigate students in learning in inequalities with one unknown, as well as to collect corresponding strategies and errors in problem solving. The subjects of this study were nine-grade students from junior high school. Six classes were selected from three schools with total of 204 students.
This investigator used a paper-and-pencil test in first round data collection. In the second round, some students were interviewed, to further understand students¡¦ way of thinking and reasons in errors produced in problem-solving procedures. Hopefully, results can be used as reference for junior high school math teacher to plan future teaching and to prepare teaching materials.
The results of the study are three: students solved linear inequalities by using 12 different strategies; students¡¦ errors can be divided into 11 types; and, the reasons for errors are mainly understanding and transforming information from problems and the determination on solutions. The students also found it difficult to understand negative fractions and negative decimals relationships (no matter in word problems or in calculation problems).
In this study, those who fail to solve problems involving inequalities with one unknown are those who cannot translate algebraic expressions or keywords. They produced errors 5 typical cases: determining objectives, integrating mathematics knowledge, using a problem solving method, calculating process, and, determining solution.
