PENEROKAAN DAN PENGESAHAN INSTRUMEN SIKAP TERHADAP MATEMATIK DALAM KALANGAN GURU MATEMATIK SEKOLAH MENENGAH

Abstract

This study aims to validate the instrument of attitude towards mathematics among secondary school mathematics teachers. This study is a completely quantitative study that uses survey methods using questionnaire procedures. A total of 100 mathematics teachers were involved as respondents in this study. The data were analyzed descriptively by access Alpha Cronbach reliability and EFA analysis using SPSS software. The results of the analysis show that Alpha Cronbach value is 0.937 which is more than 0.60. Results from the exploration factor analysis show four factors with Eigen values greater than 1.0. The KMO value (Kaiser-Meyer-Olkin) 0.867>0.6 indicates the items in the variable of attitude towards math are sufficient for inter-correlation. While the Bartlett Test was significant (Chi Square 2576.204, p <0.05), an anti-image value (Measure of Sampling Adequancy, MSA) for items correlation exceeded 0.6. However, there are 18 items that need to be removed because the values of factor loading obtained are less than 0.60, items D1, D2, D6, D7, D11, D13, D14, D15, D16, D21, D25, D26, D27, D28, D29, D30, D31 and D33. The total variance explained by the four factors is 54.5% is sufficient and acceptable as it exceeds the minimum 50%. Thus, the overall findings show that the items for the attitude instrument towards mathematics can measure and answer research questions. A total of 20 items were validated and suitable for measuring the construct of attitudes towards mathematics among secondary school mathematics teachers.
