Evaluating graphing quadratic worksheet on visual thinking classification: A confirmatory analysis

Applying a graphing quadratic worksheet as medium for learning the concept of Quadratic Function clearer is an alternative instrument to accommodate needs developing students' mathematical visual thinking. In implementing should show details dominant and recessive thinking classification aspects that develop in students. Classification be completed determine stages improving instructions are applied especially aspects. Therefore, there need evaluate factors trace developed students after practicing worksheet. The purpose this research categorization items do not Confirmatory factor analysis was employed method on 12 sub-variables from three classifications As data, 93 student records were used. Four main formed result confirmatory procedure, with top two factors, namely 1 2, completely representing each aspect achieving loading significance criteria. implication variables have strong relationship ability overall. Enhanced by cumulative variance value 2 specifically 56.88% total 81.78% all factors. Thereby it can said develops achieved sensibly.
