Abstract

This study aims to produce a mathematical learning design of two-variable linear equation system material with teachmint assisted by Microsoft Math Solver, which was carried out at SMK Kristen 2 Tomohon. This research uses the Generic EDR model by Mckenney and Reeves with the stages carried out, namely the analysis-exploration stage, the design-construction stage, the evaluation-reflection stage, the maturation stage of theoretical intervention-meaning, and the implementation stage. In the development of this learning design, there are three things that will be assessed, namely valid, practical and effective. The results showed that the average total validation score of the Teaching Module was 4.47 and the average total validation score of THB 4.55 with excellent categories that met the valid criteria. The results of the student response questionnaire showed an average total score of 4.31 which shows that the learning design is very practical. Then the percentage of completeness of the student learning outcomes test is 86.36, so this shows the design of the defender.

Abstract

This study aims to describe mathematics learning activities during the co-19 pandemic and after the co-19 pandemic at SMP N 5 Tondano. Approximately 2 years of the brave learning process was carried out, which might make students experience problems in terms of ethics or attitude because while learning, the brave teacher also lacks in supervising students' attitudes and behaviour, so with this change in learning, the difference is very visible. This research is qualitative descriptive research. Data was collected using observation techniques, interviews, and documentation. The results showed that students' mathematics learning activities during the transition/post-covid-19 pandemic were going well at school following the schedule of learning activities the school had prepared. However, students' mathematics lessons are less effective in the process. This is evidenced by observational data, which shows: 1) Teachers are less creative using various learning models, 2) Students do not respond to learning, 3) Students lack interest in mathematics, 4) Students are not actively involved in learning, and 5) Courageous learning that takes so long results in students being very dependent on the internet network. This resulted in the teacher experiencing several obstacles in the students' mathematics learning activities attractively. It can be interpreted that students' mathematics learning activities at SMP N 5 Tondano during the transition/post-covid-19 pandemic were less effective due to courageous learning activities.

Mathematics Departement. Faculty of Mathematics, Natural and Earth Sciences. Manado Dtate University. Tondano. 2023. This studies is motivated through problems determined in learning mathematics that are observed from various factors, one in every of which is the dearth of use of media. The purpose of this observe changed into to supply mastering video media products on cube and block cloth with a geogebra-assisted task primarily based mastering (PjBL) model in magnificence VIII SMP Negeri Satap Molobog which is valid, practical and effective. The ADDIE development methodology (Analysis, Design, Development, Implementation, and Evaluation) is used in this form of study, which is referred to as research and development (R&D). 16 kids from SMP Satap Negeri Molobog's eighth grade served as the study's participants. Interviews, questionnaires, learning assessment worksheets in the form of learning implementation plans (RPP), student worksheets (LKPD), and outcomes evaluation questions were all included in the study tools and documentation, data analysis to create learning media products, and knowledge of the valid, prtical, and effective of the generated goods. the share of validity of the consequences of the media professional's evaluation became 92.374% and the share of the result of the material professional's evaluation turned into 94.78% with a completely valid category. For the praticality percent of the media visible from the teacher's response of 96.36% and for student responses 94.625% within the very good category. This evolved learning media meets the effective standards based on the proportion of classical getting to know completeness of 81.25%> 75% of students who are declared to have finished getting to know the use of the learning media used. In end, the academic video media developed is valid, practical, and effective for use in learning. Keywords: Studying Movies, Project Based Learning, Geogebra, Cube and Blocks.

Abstract

This study aims to analyze students' errors in working on the System of Two Variable Linear Equations using the Newman procedure at SMP Negeri 1 Tondano. The research approach is a collective case study approach with a critical paradigm. Data was collected through interviews, written tests, observation, and documentation. In contrast, data analysis techniques include data reduction, presentation, and conclusion. The results obtained were (1) There was an error in the second stage of the Newman error procedure: students needed to understand all the questions the researcher gave. (2) In the Transformation section or the third stage in the Newman error procedure, students have not been able to convert the information obtained from the questions into a mathematical model (3) In the Process Skills section or the fourth stage, most students have not been able to work on the questions with good processing skills ( 4) then in the Answer Writing section there are primarily students who make mistakes when writing the final answer, where students do not write conclusions.

Abstract

Penelitian ini bertujuan untuk mengetahui apakah perangkat pembelajaran yang dikembangkan memenuhi kategori valid, praktis dan efektif. Penelitian ini merupakan penelitian pengembangan dan menggunakan model ADDIE (Analysis. Development. Design, Implementation and Evaluation). Persentase kevalidan dari hasil ketiga validator yaitu untuk RPP 88.09 % dan untuk LKPD 89,22 % yang dikategorikan sangat valid. Kepraktisan perangkat pembelajaran berdasarkan hasil angket respon guru dengan persentase 92% dan angket respon siswa 87% yang dikategorikan sangat praktis. Kemudian keefektifan diuji dengan menggunakan uji-t dengan memberikan posttest kepada kelas kontrol dan kelas eksperimen setelah itu membandingkan rata-rata hasil belajar kedua kelas tersebut. Hasil pengujian hipotesis diperoleh hasil thitung =   ttabel = 1,68 maka H0 ditolak. Dengan demikian dapat disimpulkan bahwa perangkat pembelajaran yang dikembangkan memenuhi kriteria valid, praktis dan efektif.
