Localized Traditional Learning Modules in the History of Mathematics its Effect to the Learning Competency of Students De Leon, Nancy G. Traditional learning modules Modular learning History of Mathematics Development and validation Learning materials Achievement In Philippine higher education, modular learning is regarded as one of the most flexible, accessible, and mobile methods of instruction. The Philippine Commission on Higher Education (CHED) also recognizes the merits of flexible learning, especially with regards to the current situation of the academe during the pandemic. In the CHED Memorandum Order (CMO) No. 4 Series of 2020, CHED pointed out the rationale behind flexible learning and the guidelines for its implementation in higher education institutions and state universities and colleges. One of the learning objects specified therein is the module, both printed and electronic. In this scenario, the researcher was motivated to develop traditional modules that employed developmental research design to d validate traditional learning modules in the history of mathematics. The researcher carried out the study from January 2020 to January 2022 academic year. Results shows that the developed learning modules' high inter-rater and intra-rater reliability were confirmed using well-known scientific methodologies. The results also revealed that the traditional learning modules had a statistically significant effect on the performances of Mathematics Major History of Mathematics course participants. The developed learning modules were acceptable based on the participants' assessments. It is proposed that further development of additional instructional approaches be carried out so that they can be used in the improved version of the traditional modules 2023-04-27T12:15:04Z 2023-04-27T12:15:04Z 2023-04-01 info:eu-repo/semantics/article Nancy G.
