# IMPROVING THE EFFECTIVENESS OF LEARNING MATHEMATICS THROUGH SCIENTIFIC APPROACH

### Abstract

This research was conducted in order to obtain empirical data on the impact of the

application of scientific approach in teaching mathematics, particularly to increase the

effectiveness of learning mathematics. This study was carried out following the procedure

of action research designed by Kemmis & Taggart. The subjects were 28 students of

class VIII-A2 SMP in Negeri 1 Singaraja in the second semester of academic year

2014/2015. A number of the data were collected with the technique to test students'

mathematics learning outcomes. The data were analyzed with descriptive statistics.The

results showed that the scientific approach in mathematics learning in class VIII-A2 SMP

Negeri 1 Singaraja in the second semester of academic year 2014/2015 increased the

effectiveness of learning mathematics. It can be seen from the increase in mastery

learning achieved by VIII-A2 from 81.84% in the first cycle to 89.29% in the second cycle

and increased to 92.86% in the third cycle as well as increased to 96.43% in IV cycle.

Based on the success indicators defined achievement of 100% completeness study, it can

be said that the action of the application of scientific approaches in the study of

mathematics has not been successful, but the statistical achievement of mastery learning

is sufficient to indicate that the scientific approach gives positive expectations in order to

increase the effectiveness of learning the tips edges improve student learning outcomes

overall. Based on these results, researchers advice to teachers is that the scientific

approach applied in the math class trying to continue to make improvements so as to

achieve the expected goals. This is very positive approach in the scientific characteristics

such as: 1) a student-centered, 2) involves the science process skills in constructing

concepts, laws or principles, 3) involves the cognitive processes of potential in stimulating

the development of intellect, especially thinking skills high level students, and 4) to

develop the student's character.
