In view of the aforementioned problem; the purpose of the study was to investigate the influence of home based factors on students’ performance in Mathematics in selected public secondary schools in Migori County. The objective of the study was to determine the influence of home learning environment on students’ performance in Mathematics in Public Secondary Schools. The study was guided by Ajzens theory of planned behavior. The study adopted mixed methods approach and its research design was descriptive survey. The targeted populations were; 185 schools and 17000 form IV students and 400 Mathematics teachers. Using simple random sampling, purposive sampling techniques and Glen’s Israel formula of getting the sample size was used to get a sample size of 56 schools and 800 students 150 Mathematics teachers. Data was collected using a questionnaire and an interview schedule for selected students and Mathematics teachers. Data was analyzed by descriptive statistics of mean, frequency, standard deviation, correlation coefficient and inferential statistics (ANOVA). SPSS Program version 23 was used in the analysis of data. The study has revealed that, home learning environment significantly predicts performance among secondary school students, F(1 690) 410.442, p< .05.enAttribution-NonCommercial-ShareAlike 3.0 United Stateshttp://creativecommons.org/licenses/by-nc-sa/3.0/us/mathematics teachers, Public Secondary Schools, learning environment.Article
