Resumen:Traditional rote learning methods often fail to adequately develop reasoning skills in mathematics, particularly among pre-university students. This study addresses challenges in fostering mathematical reasoning abilities, as evidenced by declining TIMSS results and resistance to pedagogical innovations. My online teaching with GeoGebra (MyOT_G+) kit was developed as a technology-enhanced teaching solution to improve students' understanding of propositional logic. Grounded in constructivist theory, the kit integrates GeoGebra software and Venn diagrams for an interactive learning experience, focusing on subtopics such as De Morgan's laws, conditional, converse, inverse, contrapositive, and biconditional statements. Using the design and development research approach and the ADDIE model, the study combined qualitative and quantitative methods. Phase 1 involved interviews with five mathematics lecturers and five pre-university students in Kuala Lumpur to identify instructional needs. Phase 2 focused on designing and validating the MyOT_G+ kit with input from 13 experts. Findings revealed the kit's user-friendliness, adaptability, and ability to reduce cognitive load, facilitating a deeper understanding of mathematical concepts. This study highlights the potential of integrating technology into mathematics education, offering scalable solutions for improving reasoning skills in pre-university contexts. The MyOT_G+ kit provides evidence that interactive, visual tools enhance comprehension of complex topics, with implications for pre-university education and teacher training programs.
