The Effectiveness of Elaboration Strategy in Improving Student’s Learning Achievement

Abstract

Type of this research is an experiment that involve two groups that were given different treatment. The purpose of this research are to (1) analyze the differences of learning achievement between students are taught using elaboration strategy and students who are taught using the conventional strategy, (2) determine the effectiveness of elaboration strategies in improving students' learning achievement on grade X senior high school (3) know that the learning achievement of students who are taught mathematics using elaboration strategy more effective than students who are taught mathematics using a conventional strategy. The population of this research is all students of grade X senior high school in the even semester 2010/2011 academic year and two classes are selected randomly, as the experimental unit that are year X3 and X4. Year X3 is given conventional strategy and year X4 is given elaboration strategy. Techniques of data analysis consist of descriptive and inferential statistics. The results of this research showed that: (1) mean of students’ mathematics learning achievement before being taught with the conventional strategy was in the very low category, but after being taught with the conventional strategy has an average are in the high category, (2) as well as the control class, the mean of students’ mathematics learning achievement on grade X before taught using the strategy of elaboration on the three-dimensional topic was in a very low category, but after taught with the elaboration strategy had an average in the high category (3) the results of inferential statistical analysis obtained the conclusion, there are differences in mathematics learning achievement between students who are taught by elaboration strategy and the students that is taught with the conventional strategy. From the results of this research can be concluded that the students’ mathematics learning achievement who are taught using elaboration strategy more effective than students who are taught using conventional strategy.

Key words: Elaboration strategy, Learning Achievement.
