Abstract

Industrial revolution 4.0 in which digital technology being more integrated in all aspects of human life will demand the new reform of education world. Not only can it affect the curriculum being taught, but it will also lead to the changes of the methods and approaches in conducting the lesson. One of the changes is the use of digital learning. Universitas Negeri Padang has regulation of conducting lesson through e-learning platform proportionally for all courses, including the course of Ordinary Differential Equation. Ordinary Differential Equation is a mandatory course that should be taken by mathematics department’s students. In order to support students to develop their under standing about the concept and its application while using digital learning method, the researchers develop some tutorial video as supplementary media. Therefore, this study aimed to describe the practicality of the tutorial video. This is a descriptive research where the data were collected using closed questionnaire. The respondents were 39 mathematics students of Universitas Negeri Padang who joined Ordinary Differential Equation Course in the semester of January-June 2020. The result indicates that the video tutorials used in the course are in the category of very practice with the score percentage 86,6%.

Abstract

The most essential thing in mathematics is proof, it makes mathematics being different with other subjects. One of subject in mathematics that always need prove to understand the concept is abstract algebra. In studying abstract algebra, student need various abstract concepts to include in its concepts. It is hard for student to understand the structures in abstract algebra and prove some of mathematical object that satisfy the structures. Group and its properties is the first structure in abstract algebra that has an abstract concept. It is hard for student to understand some objects, that is proven satisfy a structure and why the proof steps just flow. By giving explanation and reason in every proofing step, we try to increase student proving level and reduce the abstraction level of the concepts. To see how this module reduces the abstraction level in teaching group, this module is applied to university students and evaluated by interviewing and questionnaires to the students. Base on student response and by some perspectives, student proving ability increase and the abstraction level of the concept is diminished in some aspects.
