To support students facing rapid technological development, teachers must provide real experience in the learning process. Linear programming materials that require visualization in their understanding can be taught by integrating GeoGebra software. This community service aims to strengthen teacher skills in using GeoGebra for linear programming learning media. Community service is carried out through training and mentoring with an active learning participant approach. The activities are carried out through three core stages: teacher training in mastering the GeoGebra interface, assistance in visualizing linear programming problems, and aid in solving linear programs. Although most of the participants stated that GeoGebra could help learn linear programming in the classroom, its implementation needs to consider various aspects, such as the preparation of learning tools and equipment, learning time, and student readiness.
STEM (Science, Technology, Engineering, Mathematics) is an approach that integrates science, technology, techniques, and mathematics in learning. This study aims to determine the effect of the STEM learning approach on students’ learning outcomes on the Newton law concept. This research was conducted at SMA Darussalam Ciputat School from March 2020 to April 2020. In this study the experimental class was class X IPA 1, while the control class was X IPA 2. Determination of the sample based on this study was using purposive sampling technique. The research method used is a quasi-experimental design with nonequivalent control design. The Data from the instrument were analyzed quantitatively, producing hypothesis test data against post-test data using the Mann-Whiteney test at α = 0.05 obtained sig values. (2-tailed) of 0.00 with the conclusion that is H
0 rejected and H
1 is accepted.The learning outcomes of students in the experimental class increased higher (N-Gain 0.68) compared to students in the control class (N-Gain 0.19). Students are interested in STEM learning approach (78.25%).The STEM learning approach can be used as the main choice in implementing physics learning so that it can improve student learning outcomes.
The purpose of this research is to analyze mathematical understanding ability, especially students of mathematics education at second semester. Understanding ability that was researched is about group of algebra structure. This research use descriptif qualitative method. Subject at this research are second semester mathematics education student in Universitas Muhammadiyah Surakarta in academic year 2018/2019. Data in this research were obtained with interview, test, and documentation. Results showed student with high creative attitude has translation ability, interpretation ability, and exploration ability. Student with medium creative attitude has translation ability and interpretation ability, but hasn’t exploration ability. Student with low creative attitude has translation ability, but hasn’t interpretation ability and exploration ability
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
