Abstract

Abstrak: Penelitian ini bertujuan untuk menjelaskan tentang penerapan pendekatan saintifik dalam pembelajaran matematika dan pengaruhnya terhadap kemampuan komunikasi matematis dan berpikir kreatif siswa di Kelas X D Madrasah Aliyah Negeri (MAN) 1 Pontianak. Rancangan penelitian yang digunakan adalah One-Group Pretest-Posttest Design dengan 3 kali perlakuan 1 kali pretest dan 3 kali post-test. Setiap perlakuan dalam pembelajaran diberikan postes untuk mengetahui ada tidaknya kemampuan komunikasi matematis dan berpikir kreatif siswa. Setiap aktivitas guru dan siswa dalam pembelajaran diamati oleh observer. Hasil penelitian menunjukkan bahwa pelaksanaan pembelajaran dengan menggunakan pendekatan saintifik terdiri dari lima tahapan yaitu mengamati, menanya, mencoba/mengumpulkan informasi, mengasosiasi, dan mengomunikasikan. Kegiatan pembelajaran sudah mencapai lebih dari 75% dari rancangan yang telah disusun selama 3 kali pertemuan. Setelah dilakukan pembelajaran matematika dengan pendekatan saintifik dan pengaruhnya terhadap kemampuan komunikasi matematis dan berpikir kreatif mengalami peningkatan yaitu rerata sebesar 82,45% dan 84,48%. Serta terdapat hubungan antara kemampuan komunikasi matematis dan berpikir kreatif siswa setelah diberikan pembelajaran dengan pendekatan saintifik.   Kata Kunci: Pendekatan saintifik, komunikasi matematis, berpikir kreatif. Abstract: The study aims to explain regarding to the application of scientific approach in the Math teaching learning process and the influencing toward the ability of the mathematic communication and the student creative-thinking at the 10th grade MAN I Pontianak. The design of study used is One-Group Pretest-Posttest Design. Each treatment in the study was given a pretest to determine an increase in mathematic communication skills and creative thinking mathematic students. The teacher-students teaching learning process will be observed by the observer. The results of this research show that the application of scientific approach in math teaching and learning process comprises of five steps, namely observing, questioning, data collection, associating, and communication. Teaching and learning process has achieved more than 75% than the lesson-plan in three meetings. After the implementation of scientific approach in math teaching and learning process and the influence toward the mathematic communication ability and the students creative-thinking, show that there is an increasing of those variables has risen an average of 82,45% and 84,48%. Also, there is a correlation between the ability of mathematic communication and students creative-thinking after learning given the scientific approach. Key words: scientific approach, mathematic communication, creative-thinking.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pendekatan pendidikan matematika realistik terhadap hasil belajar peserta didik kelas XI dalam materi lingkaran di SMA Panca Setya Sintang. Metode penelitian yang digunakan dalam penelitian ini adalah eksperimen dengan rancangan penelitian one-shot case study. Populasi dalam penelitian ini adalah peserta didik kelas XI IPA SMA Panca Setya Sintang. Sementara sampel yang digunakan yaitu peserta didik kelas XI IPA 2 yang berjumlah 24 peserta didik. Teknik pengumpulan data hasil belajar menggunakan teknik pengukuran dengan mmberikan tes soal essay dalam materi lingkaran kepada peserta didik. Untuk melihat kekonsistenan dalam pencapaian hasil belajar, maka setelah dua minggu kemudian diberikan tes tunda. Besar rata-rata nilai pada saat tes akhir adalah 53,82, sedangkan rata-rata nilai pada saat tes tunda adalah 55,56. Berdasarkan perhitungan uji t tes rata-rata satu sampel diperoleh nilai  dan  dengan taraf signifikan  hal ini berarti  maka  diterima artinya tidak terdapat perbedaan yang signifikan antara rata-rata nilai peserta didik pada saat tes akhir dan tes tunda. Maka terjadi kekonsistenan antara nilai tes akhir dan nilai tes tunda, hal ini berarti penerapan pendekatan pendidikan matematika realistik pada materi lingkaran berpengaruh terhadap hasil belajar peserta didikKata Kunci : Pengaruh, Pendidikan Matematika Realistik, Hasil Belajar

Abstract

Mathematics learning has an essential role in forming and developing students' critical thinking skills. It is in line with the objectives of learning mathematics, which shows a logical, critical, analytical, careful, and thorough, responsible, responsive, and not easily give up in solving problems. Mathematics taught to students has the aim to equip students to have critical abilities. But in reality, the implementation of mathematics learning in schools has not been able to train students' critical thinking skills. This study aims to describe and find out the potential of students' critical thinking in solving problems in trigonometry in high school. The research method used in this research is descriptive with exploratory research. The subjects in this study were 30 subjects. Based on the results of this study, it was found that the potential for students' critical thinking in solving trigonometry problems was medium. Potential students' critical thinking is categorized as being because students have not been able to understand the problem displayed correctly, students have difficulty in giving arguments or reasons for the answers they have stated, students cannot identify and choose relevant information because of the available mathematical models, students have difficulty in giving questions to the information displayed.Keyword: Critical Thinking, Potential, Trigonometry

Abstract

This research aims to find the effect of applying the blended learning model to increase students' conceptual understanding and procedural fluency in statistics material in junior high schools. The Blended Learning model is used to with flipped classroom sub-model. This type of sub-model has two classes, named online and offline. For online's classes, use the help of the WhatsApp application and Google Classroom. The application of this blended learning model are expect to improve students' conceptual understanding and procedural fluency in learning mathematics, especially in statistical's subject matter to be researched in this research. This research is a type of quantitative research using experimental methods. Data collection techniques that used in this research is observation and tests. The observation in question is the teacher's observation using the observation sheet to observe the teacher's activities in teaching when the question test is a test of conceptual understanding and procedural fluency in the form of an essay test. Data analysis techniques were performed with calculating the results of the pretest and posttest in the experimental class and control class and then carrying out a Test of Normality, Test of Homogeneity of Variance, Paired Sample Test, Independent Sample Test, and concluding the results of the test. The results of the research are that both the blended learning model and the conventional learning model both have an increase. Even though there is an increase in both the blended learning model and the conventional learning model does not have a significant effect on students' conceptual understanding and procedural fluency even though the results show that there is a difference in the increase between the experimental class and the control class.

Abstract

This study aimed to (1) determine the classification of students’ response in completing story questions based on the SOLO taxonomy; (2) discover the challenges of students in completing story questions on number patterns. The methodology used in this study was descriptive qualitative with a case study approach. The participants were 22 of 8th-grade students at SMP Sugiyopranoto Sanggau and the data sources were the results of story questions on number patterns and interview transcripts with the students. The result of this study indicates that response of high-achiever students reach the relational level of 8%, the students have already understand the number pattern materials quite well, take notes all the information contained on the questions, are able to correlate the separate information properly, write down the calculation steps and the conclusions given were also relevant. The response of moderate-achiever students reach the multistructural level of 40%, the students sufficiently understand the questions, take notes several important information and utilize it at the calculation, however, the correlation of separate information and concepts were not clear so that the calculation and the answers obtained were not reasonably right. Meanwhile, the response of low-achiever students are at the unistructural level of 21%, the students were still formula-oriented, and used merely one concept or one calculation step which caused the results obtained to be incorrect.
