Abstract

The error in constructing the definition concept of function definition formally can lead into a failure in their thinking structure to understand the concept of function definition scientifically. The efforts to correct the errors that occured through the restructurisation of thinking process. Restructuring the thinking process is STEM-based so that students can understand the definition of the function as a whole, critical and creative in solving problems. This study is qualitative research to restructure of STEM-based students thinking in constructing of function definition concept based on the assimilation and accomodation process through the provision of scaffolding. The research subjects are 2 students choosen from 18 students by consideration that the students meet the determined criteria. The result are restructuring of thinking of S1 on relation error with Cartesian product scaffolding, the general definition of function with relation scaffolding, and function representation through scaffolding of function example. The restructuring of S2 thinking on cartesian product error with identifying set scaffolding, relation error with cartesian product scaffolding, general definition of function with relation scaffolding, and function representation through scaffolding of function example. The restructuring of student thinking is still weak because of the many scaffolding needed to achieve the learning objectives
