Abstract:
This study attempted to determine the effectiveness of mother tongue language in teaching word problems on multiplication of whole numbers. To achieve this aim, the researcher used an experimental research design. The instrument used for gathering data was Math periodical test prepared by the Mathematics Division Coordinators and Master Teachers.. The respondents of the research were grade three pupils in section B and D. To facilitate data analysis and interpretation, the statistical measures used were the mean, standard deviation, t-test for independent sample and t-test of correlated sample. The study determined the effectiveness of the use of Mother Tongue as a medium of instruction in teaching word problems on multiplication of whole number in a specified public elementary school, Marilao, Bulacan. The result of the study revealed that the use of Mother Tongue-Based Language and Non-Mother Tongue-Based Language are both effective in teaching problem solving in Mathematics, but the use of Mother Tongue-Based Language is more effective than Non-Mother Tongue-Based Language. Curriculum planners, publishers and textbooks writers should work together with experts in Mathematics, to produce standard text in Mathematics for the pupils' mother tongues to gain its pride of place in schools for better understanding of the subject.
