Abstract

This study aims to determine the influence of parental attention and learning motivation on mathematics learning outcomes of seventh-grade students of SMP Negeri 1 Pematangsiantar. Parental attention and learning motivation data obtained from an instrument in the form of a closed questionnaire distributed online via google form with good quality because it is valid and reliable. Meanwhile, students' mathematics learning outcomes were obtained from the school's documentation of grades. The test results show that there is a direct effect of parental attention on learning motivation with a t-count of 2.1309 and a significance level of 0.08325; there is a direct effect of parental attention on student mathematics learning outcomes with a t-count of 2.42875 and a significance level of 0.13768; there is an indirect effect of learning motivation on student mathematics learning outcomes with a t-count of 2.58298 and a significance level of 0.14988; there is an indirect effect of parental attention and learning motivation on mathematics learning outcomes. As for the contribution given by parents' attention and learning motivation to mathematics learning outcomes was 28.75% and the total effect was 42.327%. Therefore, the higher parental attention and student motivation, the higher the learning outcomes.

Abstract

The online learning system (in the network) is a learning system without face to face directly between teachers and students but is carried out online using the internet network. Educators must ensure that teaching and learning activities continue to run according to the demands of the curriculum, even though students are at home. With a situation like this, teachers are required to make learning innovations related to the media that will be used to deliver online learning effectively. The diversity of teacher competency levels in carrying out online learning requires socialization activities for online classroom management in terms of using google classroom and making learning videos uploaded to youtube. Seeing these conditions, the service team from HKBP Nommensen University lecturers collaborated with school leaders at SMA Negeri 1 Sidikalang in terms of conducting socialization activities and online classroom management training through the learning media of google classroom and making learning videos uploaded on youtube. The results of the collaboration in the form of community service activities carried out can help teachers at SMA Negeri 1 Sidikalang as evidenced by the average teacher already having online classes and being able to manage online classes through Google Classroom and make good learning videos.

Abstract

As we know that nowadays self-reliance is very important for the students in shaping their character. Lots of students are not mature because of they are not independence. The aim of this research is to empower the teachers’ understanding in implementing self-reliance based character education to the students. Methods used in this community service were socialization with PowerPoint presentation. Then sharing session with questions and answers to the presentation presented. This presentation was continued to case exposure with some reality conditions and group discussion. The location of this community service was at SMK Swasta Teladan Tanah Jawa in Simalungun Regency. Thirty-three teachers were the participants conducted on 7-8 January 2020. After collecting all the data, the researcher found that there are some results of how teachers can help to implement the self-reliance based character education such as: 1) to be active learners, 2) encouraging students in asking question when teaching and learning process for every subject, 3) teachers’ method of teaching, 4) integrating scout or boys’ brigade in the school, 5) students’ discipline to school policy, and 6) students’ freedom in using the internet as media for learning. Though there were problems in implementing the self-reliance based character education such as parents’ encouragement to school policy and teachers’ ability to implement the self-reliance in the subject, the researchers hope that this socialization can enlighten and empower teachers in implementing the self-reliance to the students for the brighter future of the students themselves and also for the advances of country.

Abstract

This study's objective was to determine the effects of the problem-based learning model on students enrolled in the mathematics education program at the Islamic University of North Sumatra while they studied to improve their critical thinking skills. This type of quasi-experimental study aims to determine how the participant's parameters are affected by the treatment. "One-group pretest-posttest design" is the name of the study's approach. The research was carried out there with the participation of 35 students from the Mathematics Study Program at the Islamic University of North Sumatra. In this study, data were collected through tests and observations. A tool for data analysis is the t-test. A computer application named SPSS version 25.0 is used to process statistical data. According to the results, using the PBL learning model has an impact on students' mathematical critical thinking skills at the Islamic University of North Sumatra's Mathematics Education Study Program. The t-test significance value of 0.0001, which is less than 0.05, supports this.

Abstract

Learning mathematics is intended so that students are able to use reasoning in identifying, analyzing and concluding a pattern and character of a mathematical object. In addition, by manipulating mathematics students will be able to generalize a concept, compile evidence or explain mathematical ideas and statements. The purpose of this study is to determine the increase in reasoning ability that occurs after implementing a realistic mathematics learning model. This study refers to a quasi-experimental research procedure with a pretest-posttest approach. The population used in this study were all students of class VIII SMP Negeri 11 Pematangsiantar with the sample being all students of class VIIIB, totaling 21 people. The instrument used in this study was a learning achievement test in the form of multiple choice objective tests with four options totaling 24 questions. The results showed that during the pre-test the average score of students was at 64.45 with a standard deviation of 4.575 and experienced an increase during the post-test with an average of 80.25 and a standard deviation of 6.25. In addition, when viewed from the completeness of learning there is also an increase, namely from 57.14 to 80.95.

Abstract

Sebelum adanya Kurikulum 2013, tujuan pembelajaran terkesan lebih mengutamakan aspek kognitif siswa, sementara aspek afektif dan psikomotor hanyalah sebagai dampak pengiring, yang belum menekankan aspek literasi matematika PISA. Penelitian ini bertujuan untuk menghasilkan soal matematika setara PISA dengan konten perubahan dan keterkaitannya yang valid, praktis, dan untuk mengetahui efek potensial soal terhadap kemampuan literasi matematika siswa kelas IX SMP dengan konteks jajanan di Sumatera Utara. Jenis penelitian adalah penelitian pengembangan. Penelitian ini akan mengembangkan 4 butir soal sejenis PISA dengan konten perubahan dan keterkaitannya dengan konteks satu butir soal kue lappet model limas, dua butir soal kue bika ambon model tabung, dan satu butir soal kue bika ambon model balok. Validitas dari soal telah tampak berdasarkan komentar validator ahli dan validator guru dan respon siswa yang menyatakan bahwa konten, isi materi, dan bahasa juga berdasarkan jawaban siswa pada tahap one-one menunjukkan bahwa soal adalah valid. Hasil pengembangan soal ini diujicobakan kepada siswa kelas IX SMP sebanyak 32 siswa dan hanya ada satu siswa yang bisa menyelesaikannya. Untuk menunjukkan data yang lebih baik lagi, soal ini perlu diujikan lagi kepada siswa kelas X SMA tentu dengan usia yang belum jauh dari usia 15 tahun, sehingga aspek efek potensial lebih tampak lagi.
