Pada penelitian ini dibahas keakurasian metode shooting/tembakan untuk menyelesaikan masalah kondisi batas Dirichlet pada persamaan Sturm-Liouville yang berbentuk persamaan diferensial orde dua, dengan kondisi batas Dirichlet. Persamaan Sturm-Liouville diselesaikan numerik menggunakan metode shooting. Simulasi numerik dilakukan dengan beberapa nilai (ukuran langkah). Keakurasian metode shooting diperoleh dengan cara dibandingkan solusi numeriknya terhadap solusi eksak, serta dibandingkan dengan solusi numerik menggunakan metode beda hingga. Hasil simulasi menunjukkan bahwa metode tembakan (shooting) menghasilkan solusi numerik yang lebih baik untuk mengaproksimasi masalah kondisi batas pada persamaan Sturm-Liouville dibandingkan metode beda hingga karena menghasilkan kesalahan numerik yang lebih kecil.

The role of learning media in the learning and teaching process is an integral part that cannot be separated from the world of education. Learning media is anything that can be used to channel messages from senders to recipients, so that they can stimulate students' thoughts, feelings, concerns, and interests to learn. Seeing the importance of media in learning, it is necessary to develop learning media that are valid and suitable for use in the learning process. In an effort to develop learning media, validation is carried out on the media that is being developed, the purpose of validating is to find out and correct errors that exist in the learning media being developed. This study aims to determine the validity of mathematics learning media using the powtoon application. This type of research is research and development (Research and Development). Based on the results of the validation, it shows that the learning media developed is valid, it can be seen from the results of the validity given by the experts (validators), both subject matter experts and language experts. The validation results obtained were 81% for material aspects and 90% for language aspects.

This study aims to observe the errors of class IX junior high school students in solving the problem of a two-variable system of linear equations in the form of a narrative math problem. The research subjects were 24 students of class IX. This research instrument uses 3 narrative mathematical problems of a two-variable linear equation system according to the Newman error analysis indicator. A qualitative descriptive approach was used in this study. The results obtained, some students have difficulty on indicators to solve problems involving a system of linear equations of two variables. Based on Newman's error analysis, the causes of student errors in solving two-variable linear equation system narrative math problems are: (1) 35% for reading errors in the very low category are caused by difficulties in interpreting the meaning of words or terms in the problem; (2) 61% for comprehension errors in the low category due to students not writing down the known and asked elements; (3) 50% for transformation errors in the very low category is due to difficulties in determining procedures and formulas; (4) 59% for process skill errors in the low category caused by errors in the calculation process; and (5) 58% for encoding errors in the low category were caused by students not writing conclusions.

The top three levels in Bloom's taxonomy of learning objectives, which includes analysis, synthesis, and evaluation, are critical thinking skills. Critical thinking abilities among students range widely. Based on aspects of critical thinking and universal intellectual standards, this research seeks to investigate the level of critical thinking competencies of tadris mathematics students in the topic of node coloring graph material. Descriptive analysis is the method of research used in this qualitative research technique. 14 fourth-semester students served as the research subjects for this study, which was carried out at the Mathematics Tadris Study Program at Institut Agama Islam Negeri (IAIN) Takengon. The tools employed include validation sheets, interview sheets, and critical thinking skills. Tests and interviews are used to acquire data. There are five stages in the critical thinking level (TBK). According to the study's findings, no pupils met the criteria for critical (TBK 3) and very critical performance (TBK 4). The subject level of students' critical thinking is based on critical thinking components, with 3 students (TBK 2) being quite critical, 10 students (TBK 1) being less critical, and 1 student (TBK 1) not being critical (TBK 0). This research demonstrates that students' critical thinking skills are still very low, hence enhancements to teaching strategies and learning activities are required.
在布鲁姆的学习目标分类中，前三个层次，包括分析、综合和评价，是批判性思维技能。学生的批判性思维能力各不相同。基于批判性思维和普遍智力标准，本研究旨在探讨节点着色图材料主题下初中数学学生的批判性思维能力水平。描述性分析是这种定性研究技术中使用的研究方法。本研究由Takengon institute Agama Islam Negeri (IAIN)的数学Tadris研究项目进行，以14名四学期学生为研究对象。所使用的工具包括验证表、面试表和批判性思维技能。测试和访谈是用来获取数据的。批判性思维水平(TBK)分为五个阶段。根据研究结果，没有学生达到批判性(tbk3)和非常批判性(tbk4)的标准。学生批判性思维的学科水平以批判性思维成分为基础，有3名学生(tbk2)非常批判性，10名学生(tbk1)不太批判性，1名学生(tbk1)不批判性(tbk0)。本研究表明，学生的批判性思维技能仍然很低。因此，需要改进教学策略和学习活动。

Analisis data yang digunakan menggunakan analisis deskriptif dan uji beda untuk mengukur pemahaman konsep menggunakan uji-t (independent sample t-test) serta uji N-Gain. \u0000Hasil penelitian ini menunjukkan bahwa hasil produk video pembelajaran interaktif layak digunakan dilihat dari hasil-validasi video pembelajaran interaktif materi fungi valid dan layak digunakan. Hasil validas-ahli materi secara keseluruhan memperoleh skor nilai rata-rata 62,5 dengan presentase sebesar 82 % dengan kategori “sangat layak’’. Hasil penilaian validasi ahli media secara keseluruhan memperoleh skor nilai rata-rata 60 dengan presentase sebesar 80 % dengan kategori “layak”. Pengaruh integrasi video pembelajaran interaktif dengan desain STAD dinyatakan berpengaruh dalam meningkatkan pemahaman konsep siswa kelas X SMA Assalam Tempuran dengan nilai uji-t (independent sample t-test) memperoleh signifikansi (2-tailed) sebesar ,001 < 0,05 sehingga H0 ditolak dan nilai N-Gain pemahaman konsep kelas eksperimen sebesar 42,2 % (dengan kategori sedang) lebih besar dibandingkan dengan kelas kontrol sebesar 25,9% (dengan kategori rendah).","PeriodicalId":33723,"journal":{"name":"Edu Sains Jurnal Pendidikan Sains dan Matematika","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82557076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
