A purpose of this thesis is to reveal errors of problem solving process of linear inequality, differences of middle school students' error type in learning ability level, and correction process of occurred errors. Data were collected to accomplish this aim through these course.
Above all, I practiced problem solving ability test which is subject to basic class and further class to know distinctions of the error type in middle school students' linear inequality problem solving process and their error type in learning ability level. A qualitative case study through personal interview was practiced with one further class student who has problems on applying part and the other basic class student who does not have clear concept of elucidation to set right errors using these analysis.
Six facts were checked out on these sources. First, second grade students of middle school make mistakes about understanding, applying techniques, carelessness, and ambiguity. Second, most second grade students of middle school made understanding error the most, but the cause is different by study achievement ability. The students having high study achievement ability made errors by carelessness secondly. On the other hand, there were errors of processing technique secondly for the students having low study achievement ability. Third, formulas or figures in Korean alphabet may help middle school students make a relation with a condition of application problems. Fourth, a relation research on considering former knowledge about problems in all bearings may fertilize middle school students' problem solving ability. Fifth, rethinking of applying problems' results on horizontal mathematics plays a revising role on errors of context and numerical formula cycle. And to conclude, specification using concrete instances may answer for generalized patterns or getting a notion on linear inequality.
