Effectiveness on the Use of Mother Tongue in Teaching the Concepts of Fraction Among Second Grade of Elementary School Pupils

This study evaluated the effectiveness of the mother tongue. It was adopted in a pre-test post-test quasi-experimental design with 82 pupils in the second-grade elementary school as samples. The test from the District Office of the Department of Education was used to collect data from the subjects. Findings showed that the use of Mother Tongue Language (MTL) is more effective than the Non-MTL teaching the concepts of fractions. It resolved that MTL could be used as a medium of instruction. It is an effective teaching-learning process.
