The results of data processing show that the developed student worksheet is very suitable for use in learning electrolyte and non-electrolyte solutions in terms of the feasibility of material, language, and graphics with a percentage of 98.2% with a very feasible category. Based on the calculation of the teacher response questionnaire to the science process skills based student worksheet, it shows that the teacher response is very good with a percentage of 93%. Thus, science process skills based student worksheet is very suitable to be used in the learning process
Praktikalitas Media Video Tutorial sebagai Suplemen Digital Learning pada Mata Kuliah Persamaan Diferensial Biasa
Full text linkIndustrial 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%

Kemampuan Penalaran Mahasiswa saat Memecahkan Masalah pada Mata Kuliah Telaah Kurikulum Matematika Sekolah Menengah
Full text linkThis study aims to analyze the mathematical reasoning abilities of students in the mathematics education study program in the secondary school mathematics curriculum review course. This research was conducted by giving quiz questions in the form of descriptions to a class of students who were then analyzed the answers. The results of the student's answer analysis show that the students' mathematical reasoning ability is still low. The low level of students' mathematical reasoning skills in general lies in the ability of students to analyze problems, make conjectures, determine relationships between variables, and identify links between processes or concepts in a given case. So that many answers from students are not logical and wrong in concluding
Dampak Perangkat Pembelajaran Matematika Berbasis Kompetensi Profesi Terhadap Kemampuan Pemecahan Masalah Siswa Bidang Keahlian Teknologi Informasi dan Komunikasi
Full text linkThis study discusses professional competency-based mathematics learning tools for vocational high school students. The purpose of this study is to produce a mathematics learning tool that refers to the field of communication and network engineering expertise, as an effort to overcome the difficulties faced by vocational school teachers in teaching mathematics. The research is a development research that refers to the development of the Plomp model with three stages, namely the preliminary research stage, the design stage and the assessment stage. In this article the results of the assessment phase will be discussed which examines the impact of devices that have been developed on students' problem solving abilities in the field of information and communication engineering. The results obtained are an increase in students' problem solving skills that can be seen in improving the ability to understand the problem, linking the problem with the concept that has been learned, setting a solution strategy, using the strategy, checking back and summarizing the results. This ability is highly needed by vocational school students, because in their work they will face many problems that require all of these abilities.
