Abstract

Penelitian ini bertujuan untuk  mengetahui pengaruh penggunaan model pembelajaran Group Investigation (GI) terhadap kemampuan komunikasi matematis siswa kelas VII SMP Negeri 1 sorkam. Jenis penelitian ini eksperimen, dengan populasi seluruh siswa kelas VII SMP Negeri 1 sorkam yang berjumlah 160 siswa yang terdiri dari lima kelas. Sampel penelitian ini yaitu kelas VII-1, ditentukan dengan cara sampel random. Data penelitian ada dua macam yaitu observasi dan tes  yang sebelumnnya telah divalidasi. Hasil penelitian menunjukkan gambaran penggunaan model pembelajaran Group Investigation (GI) diperoleh nilai rata-rata 3,67 berada pada kategori “sangat baik”. Gambaran kemampuan komunikasi matematis siswa sebelum menggunakan model pembelajaran Group Investigation (GI) diperoleh rata-rata 47,48 berada pada kategori “kurang”. Sedangkan kemampuan komunikasi matematis siswa sesudah menggunakan model pembelajaran Group Investigation (GI) diperoleh rata-rata 73,12 berada pada kategori “baik”. Berdasarkan analisis uji normalitas dan uji homogenitas diketahui bahwa data berdistribusi normal dan sampel berasal dari kelompok yang homogen. Berdasarkan hasil uji t diperoleh nilai signifikan 0,000 dengan taraf signifikan 5%. Apabila nilai signifikan dibandingkan dengan 0,05 yaitu 0,0000,05  maka hipotesis alternatif diterima atau disetujui kebenarannya. Artinya “Terdapat pengaruh yang signifikan antara penggunaan model pembelajaran kooperatif Group Investigation (GI)  terhadap kemampuan komunikasi matematis siswa di kelas VII SMP Negeri 1 Sorkam”.

Abstract

This study aims to describe students’ mathematical communication ability on the topic statistics at the eighth grade students MTs S Aek Bonban. This research was conducted by using qualitative descriptive with the informants 1 mathematics teacher and 5 students ( 1 students who has high ability , 2 students who have average, and 2 students who have low ability) as the subject of the research. Interview and test were used in collecting the data. Students who has high ability able to understand and overcome the mathematical problem well based on the indicators, students who have medium ability able to understand the mathematical problem well but they are not able to overcome the mathematical problem well based on the indicators (they able overcome 2 indicators), and students who have low ability are not able to understand the mathematical problem well and they also are not able to overcome the mathematics problem well ( they able to overcome 1 indicators).

Abstract

Problem solving ability is the most basic ability in mathematics that teacher must train students. Different learning motivation among student can affect students’ ability to solve problems. This study aims to desribe students’ problem solving abilities according to the levels of learning motivation (1) High, (2) Medium (3) Low. The subjects in this study were 24 students of seventh grade students of SMP Negeri 5 Padangsidimpuan. The method uses descriptive qualitative. Data collection techniques use questionnaires, tests, and interviews. The results shows that haigh learning motivation students have problem-solving skills that tended to be good, students are able to fulfill the four problem-solving indicators according to Polya, namely (1) understanding the problem, (2) making plans, (3) carryng out plans, (4) checking back. Medium learning motivation students have medium problem-solving abilities students are able to fulfill two or three indicators, (1) understanding the problem, (2) making plans, (3) some students have problems implementing plans for completion but some of them are able to carry out plans. Low learning motivation students are able to fulfill two indicators, (1) understanding the problem, (2) unable to determine which settlement plan to choose.

Abstract

Adapun tujuan dari penelitian ini untuk mendeskripsikan keefektifan model pembelajaran Kooperatif Tipe TPS terhadap kemampuan pemecahan masalah matematika siswa kelas X SMK Negeri 1 Angkola Timur. Penelitian ini menggunakan pendekatan kuantitatif dan desain eksperimen jenis One Group Pretest Posttest Design. Populasi dalam penelitian ini berjumlah 101 siswa. peneliti menggunakan Cluster Random Sampling yaitu pengambilan sampel yang dilakukan dengan cara acak, dimana yang diacak adalah kelasnya. Pengacakan dilakukan dengan cara diundi dengan gulungan kertas, sehingga gulungan yang terambil itulah yang menjadi sampelnya. Yang mana peneliti menentukan subjek dengan teknik cluster sampling yaitu kelompok (kelas), sedangkan menentukan objeknya dengan random sampling. Setelah peneliti mengundi lima kelompok (kelas), maka yang terpilih menjadi sampel penelitian ini adalah siswa kelas X, yaitu kelas X RPL 2 dengan jumlah 18 siswa. Data penelitian diperoleh dari hasil pengamatan keterampilan guru dengan mengguanakan instrument tes berupa pre-test dan post-test untuk siswa. Selanjutnya, data penelitian ini dianalisis dengan statistik deskriptif dan statistik inferensial dengan menggunakan taraf signifikan 0.05. Hasil dari penelitian ini menunjukkan bahwa 1) Keterampilan guru dalam menggunakan model pembelajaran kooperatif tipe Think Pair Share (TPS) menunjukkan skor 32 dengan rata-rata sebesar 3,2 berada dalam kategori baik, 2) Rata-rata kemampuan memecahkan masalah dalam matematika siswa X RPL2 SMK Negeri 1 Angkola Timur sebelum menggunakan model kooperatif tipe TPS sebesar 52,94 dan sesudah menggunakan model kooperatif tipe TPS sebesar 87,27`. 3) Hasil uji hipotesis menggunakan uji T tes anatara pretest dan postest menerangkan Asymp. Sig. (2-tailed) bernilai 0.000. karena nilai 0.000 lebih kecil dari 0.05. Artinya, penerapan model pembelajaran kooperatif tipe TPS lebih efektif dari pada pembelajarannya sebelumnya terhadap pemecahan masalah matematika siswa kelas X RPL2 SMK Negeri 1 Angkola Timur.Hasil penelitian ini dapat menjadi pertimbangan bagi guru matematika dalam menggunakan model pembelajaran kooperatif tipe TPS dalam memecahkan masalah matematika.

Abstract

This study aimed to develop a valid CORE Learning Model Textbook Integrated with the Internet of Things (IoT) based on Angkola Local Wisdom. The study employed a Research and Development (R&D) approach using the Four-D model. In accordance with the research objectives, this study implemented the define, design, and develop stages, while the disseminate stage will be conducted after the developed product has been demonstrated to be practical and effective. The study involved five validators who evaluated the validity of the developed mathematics textbook for seventh-grade students at the junior high school level. The study assessed the product's validity across four aspects: Content Feasibility, Presentation Feasibility, Language Feasibility, and Feasibility of the Applied Learning Model. The results showed that the developed textbook achieved a content feasibility percentage of 93.33% (very good), a presentation feasibility percentage of 92.44% (very good), a language feasibility percentage of 94.18% (very good), and a feasibility percentage for the use of the selected instructional approach of 92.00% (very good). Overall, the average product validity percentage reached 93.07% (very good). The very good ratings obtained across all assessed aspects, as well as the overall average score, indicate that the developed product meets the criteria for validity. Therefore, the developed CORE Learning Model Textbook Integrated with the IoT Based on Angkola Local Wisdom meets the criteria for high validity and is considered suitable for further practicality and effectiveness testing in mathematics learning.
