Abstract

The rapid development of technology requires mathematics teachers to master mathematical software applications. However, some mathematics teachers have not mastered technology in mathematics learning, especially mathematical software applications. The solution to this problem is organizing community service activities through mathematical software application training in mathematics learning. The community service activity uses training modules that provide detailed and complete explanations and examples presented excitingly, so the participants are not bored. A series of community service activities include materials delivery, training and mentoring, discussion, and evaluations. Mathematics teachers were actively involved during the activities to the end and evaluation. This community service activity aims to improve the quality of mathematics teachers in utilizing mathematical software applications in mathematics learning. The responses to the training activities were very positive, so it can be concluded that the training activities were carried out well and the achievements in accordance with the goals and targets specified.

Abstract

Natural Sciences (IPA) subjects often demand the logic of students in translating science concepts through laboratory practicum analysis for schools with complete laboratory facilities. However, for schools that lack complete laboratory facilities and do not even have a laboratory, it will be difficult to realize practical learning to support students' critical thinking processes. Especially in the midst of the Covid-19 pandemic which demands distance learning, educators find it difficult to express the aims and objectives of scientific theory which will be easier to understand if applied through practical learning. This community activity program aims to provide solutions to science teachers through training in the use of practicum-based interactive media using the proteus software application. It consists of three stages of implementation, namely preparation, implementation and evaluation. The results of the community service activities obtained are that science teachers obtain transfer of technological knowledge using interactive learning media through the proteus simulation software application and analyze the results of circuit analysis simulations in the dynamic electricity sub-chapter.

Abstract

The rapidly growing digital era demands everyone to master technology, especially students. Students are required to be technology literate, but there are still many students who are not technology literate, so they are not optimal in utilizing technology, especially in data analysis. The solution to these problems is holding service activities in the form of data analysis training using the SPSS statistical application with socialization, training and mentoring, presentations, discussion forums, and evaluations. The training activities with modules explained in detail the steps for entering data input, operating, and analyzing with examples of data, and data analysis exercises that were presented in an interesting way so that the students were not boring. Students were actively involved during the activity until the end of the activity and evaluation. This activity aims to improve the quality of students in data analysis using the SPSS statistical application. This training activity received a positive response, and the students were always active in participating in the activity until it was completed, so it can be concluded that the training activity was carried out very well and succeeded in accordance with the goals and targets set.

Abstract

Discovery learning is a learning model that is useful for developing students' mathematical reasoning skills. This research aims to develop E-LKPD based on discovery learning that are valid, practical, and effective. This research uses the ADDIE approach (Analysis, Design, Development, Implementation, and Evaluation). Product testing carried out included limited field trials to 10 students and extensive field trials to 24 students of SMP Negeri 1 Gondanglegi, Malang Regency. Data collection techniques utilize expert validation sheets, E-LKPD practicality questionnaires, and mathematical reasoning test sheets. The product validity tests conducted by experts (material, learning, and media experts) are declared valid with a score of 3.44. The product practicality test's results based on student responses obtained a score of 3.42 so it’s declared practical. The product effectiveness test's results obtained a completeness percentage of 70.8% and declared effective in learning activities. Students' reasoning ability is said to improve based on their test results. This study concludes that the E-LKPD based on Discovery Learning is valid, practical, and effective and can improve the students’ mathematical reasoning ability. It’s hoped that the E-LKPD developed used as mathematics teaching materials.
