Abstract
The objective of this study was to explore the feasibility of using the One-Variable Linear Equation Situational Test to investigate the development of the concept of one-variable linear equation for middle school students. The conduct of the first stage of this study was as follows: first, a thorough literature review was made; which was followed by interviews with middle and high school math teachers; finally a survey of the eighth-grade students was made using the ¡§One-Variable Linear Equation Concept Unstructured Questionnaire¡¨.
The second stage of this study was to devise the One-Variable Linear Equation Situational Test. First, a detailed concept map of the one-variable linear equation was made based on the results obtained in the first stage of this study. Then, a situational test of one-variable linear equation was constructed according to the map. This test was to be used later in the one-to-one interviews with twelve seventh-grade students from a middle school in Kaohsiung, who did not learn the one-variable linear equation before. These twelve subjects were randomly devided into two groups: with guidance and without guidance. The data of the math achievement tests were also collected for these subjects. The results of the test interviews were analyzed and the feasibility of using the One-Variable Linear Equation Situational Test to investigate the development of the concept of one-variable linear equation was discussed.
The analysis results of individual questions of the situational test of one-variable linear equation indicated that the concepts of one-variable linear equation for middle school students were detectable. This suggested that it was feasible to use the One-Variable Linear Equation Situational Test to investigate the development of the concept of one-variable linear equation for middle school students. All subjects who participated in this study already had some preliminary ideas of the one-variable linear equation. The factor of providing guidance would enhance the development of the concept of one-variable linear equation and it would reduce the differences in numbers of various concepts of one-variable linear equation developed among the high, medium and low achievement students. Therefore, the variable of with- or without-guidance would have some effects on the detectable concepts of one-variable linear equation by the One-Variable Linear Equation Situational Test.
