Development of a Mathematics Module using the 5E Learning Model

In the Philippines’ K to 12 curriculum, primary-grade mathematics modules have been developed in the vernacular language, aligning with the Department of Education’s (DepEd) Mother-Tongue Based Multilingual Education (MTB-MLE) policy. However, these materials are not suited for learners in some elementary schools, including the University of Northern Philippines-Laboratory Schools. Thus, this study aims to describe and develop a valid Grade 1 Module in Mathematics using the 5E Learning Model. This research utilized a descriptive-research and development (R&D) method divided into three phases: planning, designing/developing, and evaluation. The topics were based on the Most Essential Learning Competencies (MELC), prescribed by the DepEd. Using the 5E Learning Model (Engage, Explore, Explain, Elaborate, Evaluate), the parts of the module were constructed (Link to fun, Let’s start, Let’s Study, Let’s do it, Challenge Yourself) and the English language was used as a medium. The experts evaluated the module, unanimously affirming its validity—based on objectives, content, activities, assessment, and references—and its high quality in terms of relevance, clarity, appropriateness, usefulness, organization, structural design, and timeliness, deeming it an exceptional resource that the learners may use and has the potential to be an effective instructional module for both face-to-face instruction and flexible learning modality. It can help learners understand the basic principles of addition and subtraction while appreciating the module’s visually appealing design and diverse elements.
