This study determined the effect of Explicit Mathematics Instruction (EMI) on learners achievement and motivation in learning Mathematics. This study also sought to bridge how the lack of attention to problem-solving skills and pattern recognition and learners participation since a part of the strategy had learners collaboration, mastery skills, independent learning, and motivation of the students. This study sought to answer the research problems What is the learners achievement in Mathematics What is the mathematics motivation of the learners Is there a significant difference between the pretest and post-test of the students achievement What is the learners perception of explicit mathematics instruction? A mixed research method was employed in the study. The participants were Grade 9 students (n=45) in La Trinidad Academy in Imus, Cavite, Philippines. The participants were selected using convenience sampling. Four research instruments were utilized, namely: (1) EMI-based lesson plans (2) Mathematics Motivation Questionnaire (3) Mathematics Achievement Test (MAT) (4) Student Learning Experience Survey. Interpretation of gathered data was done quantitatively and qualitatively. Quantitative data were obtained from the validated 30-item achievement test and the adopted motivation questionnaire, while student responses to the learners learning experience survey instrument provided qualitative data. Descriptive and inferential statistics were utilized to determine the significant difference in the achievement before and after the EMIs implementation. The results revealed significant differences in both learners Mathematics achievement and Mathematics Motivation mean scores before and after exposure to the EMI strategy. Furthermore, the results of the survey revealed that learners exposure to the EMI strategy was effective in facilitating significant improvements in their academic achievement and motivation in Mathematics. The results signified that the implementation of Explicit Mathematics Instructions (EMI) as a teaching-learning strategy enhanced students achievement and motivation in Mathematics.
