The Effects of Geometrical Illustration on Basic Concept Understanding in Real Variable Analysis II

Abstract

This research examines the effects of geometrical illustration on Basic Concept Understanding (BCU) of students in Real Variable Analysis (RVA) II. This is a quasi-experiment research consists of two classes. They are experiment class and control class. Experiment class is class with geometrical illustration as a supplement material in instructional process, while control class is class without geometrical illustration. Subject researcher was 69 students in Mathematics Study Program Nusa Cendana University joining RVA II class in odd semester 2014/2015. Depend on the result of prior knowledge test, they were grouped by matching in to two classes. There were two subjective types of tests given in this research. They were prior knowledge test and BCU test. Data were analyzed by ANOVA. The result showed that F-value = 45.091 with the probability significance value is 0.00<0.05. It means that there is a significantly different Basic Concept Understanding of RVA between students in geometrical illustration class and students in class without geometrical illustration. Mean value of BCU in geometrical illustration class is 75.88, and that of class without geometrical illustration are 64.73. This result indicated that basic concept understanding of students in geometrical illustration class is better than that of students in class without geometrical illustration. In other word, geometrical illustration gives positive effects on basic concept understanding of students in Real Variable Analysis.
