Abstract
The aim of the study was to analyze if the interaction between mathematics and computer, could be explained by two factors: the uselfulness and inconvenient of technology through confirmatory factorial analysis. The sample size was 546 students’ of Cristobal Colon University and Autonomous University of San Luis Potosí. The data analysis was the confirmatory factorial analysis and structural equation modeling. 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) uselfulness; where the students point out that computers can help them learn better by providing several examples to work and help them to link knowledge and 2) inconvenient (disadvantages); where keyboard instructions takes care of mathematics and there is difficult to transfer understanding from the screen to themselves. Thus, finally we concluded that the model was adjusted to the data.
