摘要：This paper reports findings of a post test experimental control group design conducted t o investigate the role of modified Moore learning approach on improving students' mathematical understanding and proving abilities. Subject of study were 56 under gradute students of one state uni v ersity in Bandung , who took advanced abstract algebra cours e . Instrument of study were a set test of mathem atical understanding ability, a set test of mathematical proving ability, and a set of students' opinion scale on modified Moore learning approach . Data were analyzed by using two path ANOVA. The study found that proof construction process was more difficult than mathematical understanding task for all students , and students still posed some difficulties on constructing mathematical proof task. The study also found there were not differences between students' abilities on mathematical understanding and on proving abilities of the both classes, and both abilitie s were classified as mediocre. However, in modified Moore learning approach class there were more students who got above average grades on mathematical u nderstanding than those of conventional class. Moreover, students performed positive opinion toward modified Moore learning approach . They were active in question i ng and solving problems, and in explaining their works in front of class as well, while stude nts of conventional teaching prefered to listen to lecturer's explanation. The study also found that there was no interaction between learning approach and students' prior mathematics ability on mathematical understa nding and proving abilities, but there w ere quite strong association between students' mathematical unde rstanding and proving abilities.
