The Conceptualization Process based on Student Perspective in Solving Graph Function Problem
conceptualization, algebraic, gradient function
Abstract
The objective of this study was to analyze the conceptualization process in solving graph function problems based on the student perspective. Samples in this study were three students from the sains program in one of the best high school in West Jakarta region by the reason of testing results. This study has explored the completion of the problem and its interpretation of written interviews. There was a graph function problem that is solved by students and interpreted its completion according to their conceptions. The analyze result stated that students view the problem proposed as a function problem and not a geometric problem, so students consequences of converting from graphic to algebraic representation. The findings of this study were a conceptualization process where there are four steps of completion and it is estimating the algebraic function of the graph, finding the function of the graph, determining the function formula of the graph, and determining the derivative of the function. However, on the completion of all students, there was neglected a concept of domain function to look for as a background by students, and this is a complexity factor of the conceptualization process in solving function problems by the way to determine algebraic representation.
