A Confirmatory Factor Analysis of Pseudo-Dyscalculia Scale among Undergraduates in Ibadan, Nigeria
AbstractThis study was designed to examine confirmatory factor analysis of pseudo-dyscalculia among undergraduates in Ibadan, Nigeria using a survey design of correlational type. While 150 participants were randomly selected for the trial testing and exploratory factor analysis, a total of 800 consenting participants were randomly selected for confirmatory factor analysis. The result of the findings was analyzed using SPSS 25 and AMOS 18. The exploratory factor analysis on the scale yielded strong construct validity with a fair eight-factor structure. The results from the confirmatory factor analysis indicated a good fit for the bi-dimensional model (of Positive and Negative Affect Reactions) (X2 = 1560.009, df = 188, NFI =.910, CFI = .923, RMSEA =.059), while it indicated an excellent model-fit for the 3 model factor-structure of mathematics evaluation anxiety, learning mathematics anxiety and numerical anxiety (X2 = 4604.932, df = 699, NFI =.932, CFI = .920, RMSEA =.052). Also, observed in the result is a high rate of internal consistency among the dimensions of the scale and this ranges from 0.75 for worry to 0.97 for learning mathematics anxiety; while the entire scale garnered an overall reliability value of 0.97. Education stakeholders should take cognizance of these identified indices in order to alleviate the fear of mathematics related courses in students.
