This study aimed to develop Mathematics learning media in the form of learning videos in order to enhance the reasoning abilities of students of Mathematics Education Study Program.. This study used the development model to construct products in the form of learning videos on topics like Surface Area of Cuboid, Cube, Prism and Pyramid. To achieve this purpose, the ADDIE, Analyse, Design, Development, Implementation and Evaluation, development model was used, In this study; the steps conducted only reached the Development stage. Based on the validation of media experts, the percentage of the feasibility of learning media obtained was 95.15%. After being converted into a scale conversion table the percentage of the achievement level of 95.15% was in very good criteria. This proved that the learning video on the material surface area of the Cuboid, Cube, Prism and Pyramid were feasible to be applied in learning. Then, it was validated by material experts and based on expert validation, in terms of media aspects, material substance aspects, and learning design aspects which was scored at 90.86%. After being converted to a percentage scale conversion table the level of achievement of 90.86% was again in very good criteria. This led to conclude that the learning videos of the material surface area of Cuboid, Cube, Prism and Pyramid were feasible to be applied in research by making improvements in the order of material delivery.

Jeg er ansat som adjunkt hos Læreruddannelsen i Jelling, hvor jeg underviser i matematik, specialiseringsmodulet teknologiforståelse, praktik m.m. Jeg har tidligere været ansat som pædagogisk konsulent i matematik og tysk hos UCL ved Center for Undervisningsmidler (CFU) i Vejle og lærer i udskolingen (7.-9. klasse) på Lyshøjskolen i Kolding. Jeg er ejer af og driver bl.a. hjemmesiderne www.lærklokken.dk og www.iundervisning.dk, ggbkursus.dk og er tidligere fagredaktør på matematik på emu.dk. Jeg går ind for, at læring skal være let tilgængelig og i størst mulig omfang gratis at benytte.
