Variables to measure interaction among mathematics and computer through structural equation modeling

The purpose of the study was to analyze if the interaction between mathematics and computer, could be explained by two factors: the usefulness and inconvenient of technology through confirmatory factorial analysis. Were used the confirmatory factorial analysis and structural equation modeling in order to data analysis obtained of the 164 students surveyed at Universidad Politécnica de Aguascalientes. In order to evaluate model were considered measures of adjustment; Chi2, Chi square/degree of freedom ratio (CMIN/Df), Roots Means Square Error of Approximation (RMSEA), Goodness of Fit Index (GFI); Comparative of Fit Index (CFI) and Adjusted Goodness of Fit Index (AGFI). The results support a model of two components: 1) The inconvenience: where the student indicate that “I find it difficult to transfer understanding from a computer screen to my head” and “I rarely review the material soon after a computer session is finished”, and 2) The usefulness: where students reported that “By looking after messy calculations, computers make it easier to learn essential ideas” and “Computers help me to link knowledge e.g. the shapes of graphs and their equations.”
