This study aims to describe the models of the effect of social environment on individual aspects (academic procrastination, self-regulated learning, and self-efficacy) and their relationship with the academic achievement of the students of mathematics education departments. The population was 1.285 under graduate students of mathematics education departments at three universities in Jambi. The sample was established purposively along with the stratification sampling, from which subsequent subjects were randomly selected 260 students from the population. The data were collected through Likert-scale. The instrument validity was in term of the content validity and construct validity. The data were analyzed using the structural equation modeling (SEM), confirmatory factor analysis (CFA), and t-test. SEM and CFA were used to test quantitatively the model of simultaneous causality, either directly or indirectly and to test whether the theoretical constructs were supported by the data collected, while the t-test were used to find out statistically the differences of the mean score of each variable in terms of gender. The result of the study shows that the structural equation model developed appropriate (fit) with the data collected. It was found that gender affects the differences in all variables, except the reasons for procrastination. The result also indicate that there are effect of social environment on individual aspects (academic procrastination, self-regulated learning, and self-efficacy) and there is relationship with the academic achievement of the students of mathematics education departments.
