Appropriateness of Mnemonic Techniques on Mathematics and Social Studies Learning Outcomes in Public Primary School in Machakos Sub-County, Kenya

Abstract

The purpose of this study was to investigate the appropriateness of Mnemonic techniques on mathematics and social studies learning outcomes in primary schools in Machakos subcounty, Kenya. A 4x2 Factorial research design was used to test the appropriateness of three Mnemonic techniques on learning outcomes of mathematics and social studies. Stratified sampling technique was used to categorize schools into three educational zones in Machakos Sub-County. Four schools were then purposefully selected which had similar mean grades in KCPE exams from the three zones. Random sampling was used to assign experimental and control groups. A sample size of 317 class 7 pupils were selected for the study. The following instruments were: Tests which were used to measure learning outcomes of mathematics and social studies. Observation schedule which were as a monitoring tool during Mnemonic techniques intervention process. Questionnaires which were used to measure reported enjoyment and satisfaction among learners during Mnemonic techniques intervention process. Piloting was done in Kathiani Sub-County. Validity and reliability of the research instruments was determined by the split-half correlation method. One-way ANOVA was used to analyse the data. Post-hoc pairwise comparison (LSD) was performed to establish which groups were responsible for the differences. The main findings of the study were: No significant differences (F(3,147)= 0.052, P< 0.05) were found in mathematics learning outcomes between learners using the three Mnemonic techniques. Hence none of the three Mnemonic techniques was found to be more appropriate for mathematics. In social studies, significant differences (F(3,146) = 4.25, P< 0.05) were found between learners using the three Mnemonic techniques. Music Mnemonic technique was most appropriate for social studies pegword, keyword and control group were second, third and fourth respectively. Recommendations of this study was; The findings of this study were based on mathematics and social studies, in order to further contribute to the understanding of the relationship(s) between Mnemonic techniques and learning outcomes a similar study should be replicated in other subjects.
