This study aims to comprehensively analyze the increase in mathematical beliefs of pre-service teacher of mathematics education at Siliwangi Tasikmalaya University through learning based on the Valsiner Zone in total and based on Mathematical Preliminary Ability (MPA). The method used in this research is quasi experiment, with research population that is pre-service teacher of mathematics education at Siliwangi University of Tasikmalaya and the sample is student who follow course of probability theory in semester V consisting of one experiment class with amount of 42 people and one control class which amounted to 40 people in the Mathematics Education Study Program. Random sampling by class. Data collection techniques are questionnaires of mathematical belief scale. Descriptive analysis there is an improvement of mathematical belief of student in probability theory course, both at theory valsiner class and control class. Further improvement in student mathematical belief with theory valsiner class modeling was higher than that of control class, from the average gain of normalized students in upper, middle and lower MPA categories in the experimental group compared with the mean of normalized student gain in upper, middle and lower MPA categories with the control group although both groups were in the moderate category. © 2019 IOP Publishing Ltd.
