Abstract

Critical thinking can be surely taught and practiced for all educational graders. However, in educational field, it is still few teachers who facilitate students’ mathematics critical thinking. The aims of this study is to know whether the implementation of practical learning method significantly affects students’ mathematics critical thinking skills in learning mathematic at junior high school. The significances of the study are to give students’ active role in learning process, to improve students’ comprehension towards mathematic concept, and to upgrade students’ mathematics critical thinking. This research method is experiment method with design path analysis. The population was taken from all eighth graders which are 265 students of SMP N 3 Sumber period 2014/2015. The, the random sampling was used to gain 44 students of VIII E grade. The technique of data collection including questionnaire and essay test was used. The results of questionnaire showed that 25 or 57 % students gave responses very positively toward the implementation of practical learning method. Then, 19 or 43% students gave positive response toward the implementation of practical learning method. The result of t-test showed that there is a linier relationship between practical learning method and mathematics critical thinking with  = 1,341 X. Coefficient with positive response means that there is a significant relationship between practical learning method and mathematics critical thinking by implementing practical learning methods very often may improve students’ mathematics critical thinking. According to the result of t-test, it is showed that taccount = 6,509 > ttabel = 2,020. It can be concluded that the implementation of practical learning method significantly affect students’ mathematics critical thinking at VIII E grade of SMP Negeri 3 Sumber Kabupaten Cirebon.Keywords : Practical Learning Methods, Critical Thinking Skills

Abstract

Tulisan ini membahas kajian sifat-sifat modul P-Bézout melalui idealisasi. Modul P-Bézout pada tulisan ini hanya berupa modul Bézout. Kajian sifat-sifat tersebut dilihat dari sisi kecukupan sebagai bahan ajar perkuliahan Teori Gelanggang dan dari sisi pembentukan karakter mahasiswa. Pola penyampaian dalam proses penguasan materi berbanding lurus dengan pertumbuhan karakter positif mahasiswa khususnya berupa sifat kritis dan kreatif sebagai titik tolak terbentuknya pribadi guru yang mandiri dan berwibawa karena mampu memberikan kebutuhan siswa dari sisi materi dan kepribadian.

Abstract

The purpose of this research was to mapped the higher order thinking skills of students in solving PISA and TIMSS standards based test item based on indicators that had been compiled, as one of the effort to determine the right thing to do to increase the quality of education. The indicators in this research were the ability of analysis, evaluation, and creation. This research use a descriptive qualitative and quantitative approach. The data collection methods in this research were documentation, test, and interview. From 71 students spread across many Junior High Islamic Scoolls in Cirebon city, 2 students classified as having high order thinking skills with moderate level. Students in moderate level are found to be able to perform analysis, evaluation, and creation well in resolving some of the problems. Furthermore, 69 students are not able to perform analytical skills, evaluation, and creation well in solving all the problems, so they are considered to have low level in high order thinking skill. The difference of the student’s ability due to the lack of motivation students and teachers in improving the ability of HOTS in learning. An increase in HOTS of students can be done to improve standards evaluation, improve the quality of the process and the result of learning, as well as increase the motivation students and teachers. This research can be applied to measure student’s high order thinking skill in order to increase  the quality of education according to international standards.

Abstract

Salah satu faktor yang dapat mempengaruhi sumber daya manusia (SDM) adalah pendidikan. Salah satu mata pelajaran yang diberikan dari awal proses pendidikan adalah pelajaran matematika. Matematika merupakan salah satu mata pelajaran yang sangat penting. Pada kenyataannya matematika menjadi salah satu mata pelajaran yang paling tidak disukai para siswa. Salah satu cabang matematika yang diajarkan di sekolah adalah geometri. Kenyataan di lapangan menunjukkan bahwa materi geometri kurang dikuasai oleh sebagian besar siswa.Salah satu faktor yang akan diteliti adalah tingkat kemampuan berpikir geometri siswa. Tujuan dari penelitian ini adalah: untuk mengetahui tingkat berpikir geometri siswa, untuk mengetahui kemampuan siswa dalam mengerjakan soal pada materi garis dan sudut dan untuk mengetahui pengaruh antara tingkat kemampuan berpikir geometri (teori Van Hiele) siswa dengan kemampuan siswa mengerjakan soal pada materi garis dan sudut. Tingkat kemampuan berpikir geometri adalah kedudukan atau posisi siswa berdasarkan pada kemampuan siswa untuk menangkap serta mampu mengungkapkan pola–pola visual.Salah satu teori yang yang membahas masalah ini adalah teori Van Hiele. Kemampuan mengerjakan soal adalah kapasitas atau kecakapan individu dalam mengerjakan atau memecahkan pertanyaan. Materi garis dan sudut adalah salah satu materi yang di ajarkan dalam mata pelajaran matematika, khususnya pada kelas tujuh (VII). Peneletian ini merupakan penelitian kuantitatif dengan one-shot casestudy. Teknik pengumpulan data menggunakan tes yang berupa tes essay. Penelitian ini dilakukan di kelas VII SMP Negeri 1 Ciledug, dengan jumlah populasi sebanyak 358 siswa dan jumlah sampel sebanyak 40 siswa. Penelitian ini menyimpulkan bahwa tingkat kemampuan berpikir geometri siswa kelas VII di SMP Negeri 1 Ciledug bervariasi, yaitu 13 siswa atau 32,5% siswa berada pada tingkat 1 atau tahap pengenalan, 22 siswa atau 55% siswa berada pada tingkat 2 atau tahap analisis, 5 siswa atau 12,5% siswa berada pada tingkat 3 atau tahap pengurutan serta belum ada siswa yang berada pada tingkat 4 (tahap deduksi) dan tingkat 5 (tahap rigor). Kemampuan siswa dalam mengerjakan soal pada materi garis dan sudut termasuk dalam kategori baik.Sebanyak 21 siswa atau 52,5% siswa mendapat nilai di atas KKM yang ditetapkan di sekolah tersebut. Berdasarkan perhitungan analisis regresi, dapat disimpulkan bahwa pengaruh tingkat kemampuan geometri siswa terhadap kemampuan siswa mengerjakan soal garis dan sudut sebesar 60,6% dan selebihnya dipengaruhi faktor lain. Karena thitung>ttabel (7,651 > 2,023), maka tingkat berpikir geometri siswa mempunyai pengaruh yang signifikan terhadap kemampuan siswa dalam mengerjakan soal garis dan sudut, dengan persamaan regresi yang dihasilkan adalah Ŷ = 41,189 + 28,951 . Kata Kunci : berpikir geometri, teori van Hiele

Abstract

Congklak is a traditional game that has a long history and contains philosophies in its development. The aim of this study is to explore congklak from ethnomathematics side so that they can know the cultural value of traditional congklak games and their connection to mathematics, describe the mathematical elements contained in congklak and to find out the role of congklak in mathematics learning. This research uses qualitative research approach with type of ethnographic research supported by literature research methods. Data collection techniques that researchers do use interviews, observations, documentation, and literatur studies. This research instrument is the researcher himself using recorder aids, cameras, and stationery. The results of ethnomathematic exploration in traditional congklak games are seen from the mathematical elements, namely there are arithmetic, geometry, graphs, and probability. Cultural elements in congklak are honesty (sportive), accuracy, patience, and sharing. Congklak in mathematic learning act as ethnomatematics-based learning media. The results of this study are as information for teachers to make congklak as a medium of mathematics learning both as conventional and digital games
