Abstract

Metode statistik membantu mengorganisasi data hasil belajar, baik itu dalam penyajian, pemusatan, dan penyebaran data. Selain membantu membuat keputusan yang tepat, pemahaman statistik merupakan dasar untuk membangun keahlian berpikir. Tujuan dalam pengabdian ini adalah sosialisasi penggunaan metode statistika untuk menganalisis data evaluasi hasil belajar siswa, Metode pelaksanaan yang digunakan adalah Focus Group Discussion (FGD) dan dilanjutkan dengan pelatihan penggunaan metode statistik secara daring melalui platform google meeting, dan diakhiri dengan evaluasi hasil kegiatan. Hasil pengabdian ini menunjukkan bahwa pelatihan secara daring dan evaluasi hasil kegiatan guru yang didasarkan pada focus group discussion (FGD) mengungkapkan bahwa kinerja guru dalam menggunakan metode statistika untuk analisis data evaluasi hasil belajar siswa terkategori mampu memahami dan mampu membuat alat evaluasi sederhana baik itu berbasis excel dan google form. Sehingga dari kegiatan ini, telah memberikan kesempatan unik para guru dalam memahami statistik pada tingkat konseptual tanpa terlalu terjebak dalam persamaan dan rumus.  Use of Statistical Methods to Analyze Learning Outcome Evaluation Data at SMPN 1 Gerung, West Lombok Regency Statistical methods help organize data on learning outcomes, both in presenting, centralizing, and disseminating data. In addition to helping make the right decisions, understanding statistics is the basis for building thinking skills. The purpose of this service is to socialize the use of statistical methods to analyze student learning outcomes evaluation data. The implementation method used is focus group discussion (FGD) and is followed by training on the use of statistical methods online through the google meeting platform, and ends with an evaluation of the results of activities. The results of this service show that online training and evaluation of the results of teacher activities based on focus group discussions (FGD) reveal that teacher performance in using statistical methods for data analysis of student learning outcomes evaluation is categorized as being able to understand and be able to make simple evaluation tools both excel-based and google forms. Thus, this activity has provided teachers with a unique opportunity to understand statistics at a conceptual level without getting too caught up in equations and formulas.

Abstract

Pembelajaran matematika realistik, pembelajaran diawali dengan menggunakan masalah kontekstual, masalah yang berkaitan langsung dengan lingkungan keseharian atau pengetahuan yang telah dimiliki siswa. Pembelajaran tidak dimulai dari sistem formal matematika. Masalah kontekstual yang diangkat sebagai topik awal pembelajaran harus merupakan masalah sederhana yang dikenali oleh siswa. Ada tiga prinsip utama dalam pembelajaran dengan menggunakan pendekatan PMR, yaitu: 1) guided reinvention and progressive mathematizing; 2) didactical phenomenology; dan 3) self-developed models. Selain itu, akan ditampilkan bagaimana menerjemahkan pembelajaran matematika realistic ke dalam pembelajaran matematika.

Abstract

Penelitian tindakan kelas ini dilatarbelakangi oleh rendahnya aktivitas dan prestasi belajar matematika siswa kelas VIIIB MTs. Darul Quran Bengkel. Hal ini menjadikan aktivitas belajar siswa berkurang dan berakibat pada rendahnya prestasi belajar matematika siswa. Untuk mengatasi permasalahan ini, guru perlu menerapkan suatu strategi pembelajaran yang mampu menekankan keterampilan proses dalam upaya meningkatkan peran aktif dan prestasi belajar siswa di kelas, salah satu alternatifnya dengan menerapkan pembelajaran Think-Talk-Write (TTW). Adapun tujuan dari penelitian ini yaitu untuk meningkatkan aktivitas dan prestasi belajar siswa pada materi pokok lingkaran di kelas VIIIB MTs. Darul Quran Bengkel. Penelitian ini dilaksanakan dalam dua siklus dengan masing-masing siklusnya terdiri dari 3 kali pertemuan. Setiap siklus terdiri dari tahap perencanaan, pelaksanaan tindakan, observasi, evaluasi, dan refleksi. Data prestasi belajar siswa diperoleh melalui evaluasi hasil belajar tiap akhir siklus, sedangkan data aktivitas guru dan aktivitas belajar siswa diperoleh melalui lembar observasi. Hasil penelitian menunjukkan terjadi peningkatan rata-rata skor aktivitas dan prestasi belajar siswa dari siklus I ke siklus II. Perolehan rata-rata skor aktivitas siswa pada siklus I dan siklus II berturut-turut adalah 12,5 yang berkategori aktif dan 14,67 yang berkategori sangat aktif. Kemudian nilai rata-rata kelas siswa untuk siklus I dan siklus II berturut-turut adalah 66,6 dengan ketuntasan belajar 75% dan 73,8 dengan ketuntasan belajar 78,38 %. Dengan memperhatikan hasil serta indikator keberhasilan yang tercapai, maka dapat disimpulkan bahwa penerapan strategi pembelajaran Think-Talk-Write (TTW) dapat meningkatkan aktivitas dan prestasi belajar siswa pada materi pokok Lingkaran di Kelas VIIIB MTs. Darul Quran Bengkel.

Abstract

This research aims to determine the effect of problem-based learning model on student’s mathematical logical thinking abilities and the amount of it. To achieve the goals, this research used post-test only control group design. This research was held in class XI-IPA of SMAN 1 Sekotong and consist of 60 students which divided into two classes. By considering the post-test only control group design which requires a control group and the experimental group, used saturated sampling technique that took the whole population as the sample. The members of the population were all students of class XI-IPA of SMAN 1 Sekotong which divided into two classes XI-IPA 1 and XI-IPA 2. The instruments were used to measure the student’s logical thinking ability consist of four description. The measurement of the logical thinking ability was measured after the implementation of problem-based learning for four times. The level of compliance to the learning model was measured by observation of student and teacher activity sheets. The results of data analysis using t-test showed that problem-based learning have a significant influence on the mathematical logical thinking ability. Those results were showed by the increasing of mathematical logical thinking ability in each meeting. The analysis using the effect-size gave the result of the d value of 1,60 which means the application of problem-based learning have a high influence to the student’s mathematical logical thinking ability.

Abstract

This study aims to describe the errors and the causes of errors in solving mathematics word context problem in the topic of absolute value. Based on Newman’s Error Analysis terms of student’s lerning styles. Error analysis must continue to be carried out so that teachers know the types, causes, and solutions to overcome student errors. This type of research is descriptive qualitative.The research subjects of class X MIA 1 SMAN 1 Janapria academic year 2020/2021 were selected by purposive sampling. To deepen the research results, 2 students were selected from each type of learning style. Data collection techniques used are learning style questionnaire, diagnostic tests, and interviews. Data analysis technique used data reduction, data presentation, and conclusion. Based on the results of the data is (i) students with visual learning style and audits mostly made errors in stage of transformation, process skill, and encoding. While students with kinesthetic learning style mostly made errors in stage of comprehension, transformation, process skill, and encoding, (ii) the causes of mistakes for both students with visual, auditory, and kinesthetic learning styles are that students less understanding of the prerequisite lessons, cannot make mathematical models, and not know the steps to solve problems.
