This study investigated the effects of mobile application for learning Mathematics (MALMath) in Grade 8 students at San Jose High School of Sinayawan Inc., Valencia City, Bukidnon. Specifically, it aimed to determine the level of students' self-concept in terms of self-image, self-esteem, and ideal self; identify the level of students' self-efficacy in terms of mastery experiences, vicarious experiences, social persuasion, and emotional and physiological states; and describe the level of students' conceptual understanding in pretest and post-test when exposed to MALMath. Also, it aimed to find out if there is a significant difference in students' self-concept, self-efficacy, and conceptual understanding in pretest and post-test when exposed to MALMath. Quantitative research involving a one-shot pretest-post-test research design was employed in this study. A teacher-made conceptual understanding test and an adapted self-concept and self-efficacy test scale were used as the instruments. Descriptive statistics were used to describe the levels of students' self-concept, self-efficacy, and conceptual understanding. Also, a parametric paired t-test was used to test the significant difference in the gathered data. Research results revealed a moderate level of self-concept and self-efficacy after their exposure to MALMath. While, the results showed a lack of conceptual understanding of students after their exposure to MALMath. Further results indicated no significant difference in students' self-concept, while significant differences in students' self-efficacy and conceptual understanding were shown after their exposure to MALMath.
