A Scale Development Study Intended for Mathematics Teacher Candidates: Mathematical Visualization Perception Scale

Abstract

The aim of this study is to develop a valid and reliable measurement tool that measures mathematical visualization perceptions for mathematics teacher candidates. Therefore, the type of study is a survey research. Research was carried out with 462 (336 Female, 125 Male) mathematics teacher candidates from a university located in the Eastern Anatolia region Turkey in 2018-2019 spring season. Exploratory and confirmatory factor analyzes were performed for the analysis of research data. In the process of development of Mathematical Visualization Perception Scale (MVPS); the preparation of the pool of material, testing of the validity of the scope and appearance, conducting the trial application, ensuring the construction validity, calculating the reliability and establishing the final scale were followed. As a result of the exploratory factor analysis, a valid and reliable 5-point Likert-type scale consisting of 42 items, with 6 factors [Additional Drawing (AD), Spatial Thinking (ST), Direction Concept (DC), Relation with Daily Life (RDL), Transition from Algebra to Geometry (TAG) and Transition from Geometry to Algebra (TGA)] was created. Cronbach Alpha internal stability coefficient of these factors was calculated as 0.938. The factor structure of the scale was also confirmed by confirmatory factor analysis. As a result of the findings obtained, it was suggested to the researchers who will study in the related field to evaluate mathematical visualization perceptions of mathematics teacher candidates by using related scale with different sample groups or different variables.

A Research about Mathematical Visualization Perceptions of Mathematics Teacher Candidates in Terms of Some Variables

“…The scale has 6 factors and these factors and Cronbach Alpha values are as follows: Additional Drawing (0.971), Spatial Thinking (0.977), Concept of Direction (0.976), Relationship with Daily Life (0.976), Transition from Algebra to Geometry (0.984) and Transition from Geometry to Algebra (0.987). Also, the Cronbach Alpha value of the scale was 0.938 and it was found to be 0.868 for this study(İlhan & Tutak, 2021). The sample items related to the Mathematics Visualization Perception Scale are as follows: "If there is more than one additional drawing in a question, I believe that I can solve that question", "I can find the location of the vehicle I transport or park outside", "I can use what I learned in geometry in problem situations I encounter in my daily life", "Verbal I do not have difficulty solving geometry questions given as" I like algebraic operations in solving geometry problems.…”

“…Mathematics Visualization Perception Scale was developed byİlhan & Tutak (2021). The scale consists of 42 5-Likert type items.…”
