함수 문제해결 과정에서 범하는 오류 교정방안에 관한 연구

Abstract

This study was conducted with prior studies of error types that occurred in function units in middle school and high school. This study mainly focuses on the units of direct and inverse proportions, function and function value, graph of linear and quadratic functions in middle school courses; the maxima and minima of quadratic function, function and graph, and composite function in high school courses will be also evaluated. It is necessary to understand the definitions of terms related to function units such as direct proportions, inverse proportions, functions, etc. by providing guidance for each unit according to the analyzed research results, and presenting various examples can further help understanding each concept. In addition, learning tools should be utilized to intuitively understand through educational software such as GeoGebra to accurately understand the features of the graph of the function.Understanding the functional formula to find the parallel shift of the quadratic function allows us to understand the principle by finding the function value rather than mechanical memorization and drawing the graph directly. In addition, since it is important to obtain an answer within the given range for the questions about the maximum and minimum values of the quadratic function, it is critical to check and apply them before solving the problem. The cause of each error is closely related, so it is not easy to distinguish them. Therefore, in order to reduce the error, it is very important to find the cause of the error that students make during the process of solving the problem, and also suggest corrective measures accordingly.
