An evaluation of the motivational effectiveness of the DOST courseware modules on Arithmetic and Geometric sequences was conducted among the Grade 10 students of Los Ba?os NHS-BM. Instructional Materials Motivation Survey (IMMS), open ended questions and one sample pretest-posttest design were used in this study. The results were analyzed and explained using descriptive statistics, measures of central tendency and t-test on paired samples. This study showed that students had positive perception on the motivational effectiveness of the DOST Courseware modules in Arithmetic and Geometric sequences and proved that DOST courseware modules were effective ?New Normal? remediation tools. Future researches may be undertaken to further analyze the use of the DOST Courseware modules in evaluation and correlation between perception and purpose of instruction, usability and sustainability.
