Abstract

Pada abad 21 diperlukan keterampilan berpikir tingkat tinggi (HOTs) yang mencakup kemampuan berpikir kritis dan berpikir kreatif. Tujuan penelitian ini adalah untuk mendeskripsikan kemampuan interpretasi, analisis, inferensi, kelancaran dan orisinalitas siswa dalam menyelesaikan soal pola dan barisan bilangan. Metode yang digunakan dalam penelitian adalah deskriptif kualitatif dan subjek sebanyak 40 siswa yang terdiri 19 siswa SMPN 5 Bantan dan 21 Siswa MTS Al-Huda. Instrumen yang digunakan berupa (1) tes tertulis yang berorientasikan HOTs dan (2) pedoman wawancara.  Hasil tes menunjukkan rata-rata HOTs siswa SMPN 5 Bantan (49,34) dan MTS Al-Huda (45,12) berkategori cukup.  Skor tiap indikator HOTs untuk siswa SMPN 5 Bantan diketahui bahwa interpretasi= 48,68, analisis= 40,13, inferensi= 64,47, kelancaran= 52,68 dan orisinalitas= 40,79 sedangkan untuk siswa MTs Al-Huda adalah interpretasi= 61,18, analisis= 40,79, inferensi= 53,57, kelancaran= 38,16 dan orisinalitas= 45,24. Berdasarkan hasil wawancara juga diketahui bahwa rendahnya HOTs siswa dikarenakan siswa tidak terbiasa dalam menyelesaikan soal HOTs serta tidak tersedianya soal-soal HOTs yang secara khusus mengukur HOTs di sekolah, sehingga diharapkan adanya penelitian lebih lanjut mengenai soal-soal HOTs.Students' Thinking Ability in Solving HOTs Questions on Material Patterns and Rows of NumbersAbstractIn the 21st century, higher order thinking skills (HOTs) are needed which include critical thinking skills and creative thinking. The purpose of this study is to describe the students’ ability of interpretation, analysis, inference, fluency and originality in solving questions about patterns and rows of numbers. The method used in this research is descriptive qualitative and as many as 40 students consisting of 19 students of SMPN 5 Bantan and 21 students of Al-Huda MTS. The instrument used in the form of (1) written tests oriented to HOTs and (2) interview guidelines. The test results showed the average level of SMPN 5 Bantan students’ HOTs (49.34) and MTS Al-Huda (45.12) was categorized as sufficient. The score of each indicator of HOTs for SMPN 5 Bantan students is known that interpretation= 48.68, analysis= 40.13, inference= 64.47, fluency= 52.68 and originality= 40.79 while for MTs Al-Huda students are interpretation= 61.18, analysis= 40.79, inference= 53.57, fluency= 38.16 and originality= 45.24. Based on the interview results it is also known that the low level of students’ HOTs is because students are not accustomed to solving HOTs questions and the unavailability of HOTs questions that specifically measure HOTs in schools, so it is hoped that further research on questions of HOTs.

Abstract

Salah satu rekomendasi asesor pada visitasi BAN PT dalam rangka Akreditasi Jurusan Tadris IPA Biologi, Fakultas Tarbiyah dan Keguruan UIN Mataram adalah praktikum Laboratorium IPA dilakukan dengan pola 10x1, sementara penyelenggaraan praktikum yang umum dilaksanakan adalah pola blok 1x10. Tujuan penelitian eksperimental ini adalah menguji efektivitas penyelenggaraan praktikum pola blok 1x10 dan 10x1 sebagai acuan kebijakan praktikum Laboratorium IPA. Efektivitas dilihat dari tiga komponen, yaitu: nilai tes praktikum, nilai laporan praktikum, dan preferensi praktikan dan co-asisten terhadap salah satu pola praktikum. Penelitian dilakukan pada mahasiswa Jurusan S1 PGMI Semester II, Jurusan Tadris IPA Biologi Semester IV, dan Co-Asisten. Rancangan penelitian adalah quasi eksperimental dengan tipe Pre-test–postest Non-Equivalen pada sampel yang diambil secara cluster random sampling. Data dikumpulkan dengan teknik tes, angket, dan wawancara untuk kemudian dianalisis dengan statistik inferensial pada taraf signifikansi 0,05. Hasil penelitian menunjukkan, bahwa nilai tes dan nilai laporan praktikum mahasiswa yang mengikuti praktikum pola blok 10 x 1 lebih tinggi dibanding 1 x 10, tetapi tidak berbeda secara signifikan. Berdasarkan analisis diperoleh 96% mahasiswa lebih menyukai pola praktikum 10 x 1. Dengan demikian, ditinjau dari hasil, salah satu pola praktikum tidak ada yang lebih efektif dibanding yang lain.Organizing Practicum of 1 X 10 and 10 X 1 Block Patterns as a Reference for Science Laboratory Practicum PolicyAbstractOne of the recommendations from BAN PT assessors during the visitation in the Accreditation of Department of Natural Sciences, Faculty of Education and Teacher Training is that practicum at Natural Science Laboratory should be administered in a 10x1 block pattern, while the general administration of practicum pattern is a 1x10 block pattern. This experiment aimed at investigating the effectiveness of the administration of the 1x10 and 10x1 block practicum patterns. The effectiveness was sought out by assessing three components, namely: practicum test scores, practicum report scores and the preferences of practicants and co-assistants to one of the practicum patterns. The participants of this study were the second year undergraduate students of elemetary Education Department and the fourh year undergraduate students of Natural Science Education Department, and co-sssistants. This study was of quasi-experiment using Non-Equivalent Pre-test-postest design and the sample was taken using cluster random sampling technique. The data were collected through test, questionnaire, and interview and then they were analyzed using inferential statistics at the 0.05. significance level. The findings showed that the test and practicum report scores of the students who joined the 10 x 1 block practicum pattern were higher than those who joined 1 x 10 block practicum pattern, yet they did not differ significantly. Based on the analysis, 96% of the students obviously preferred the 10 x 1 block practicum pattern. Thus, based on the results, no one practicum pattern was more effective than the other.

Abstract

Tujuan penelitian ini adalah mendeskripsikan secara komprehensif perbedaan bukti yang membuktikan dan bukti yang menjelaskan berdasarkan pertimbangan implikasi kedua bukti tersebut sebagai dasar konstruksi penalaran dan bukti dalam matematika. Kajian dijalani dengan kegiatan menguraikan perbedaan spesifik antara keduanya serta memberikan contoh kasus kedua bukti, dan memberikan justifikasi atas pentingnya pengenalan kedua bukti dalam kelas matematika. Kedua bukti digambarkan dengan permasalahan konsep barisan bilangan ganjil. Bukti yang membuktikan hanya menunjukkan dengan menggunakan induksi matematis, sementara bukti yang menjelaskan menunjukkan dengan bukti Gauss, representasi geometrik bangun titik, dan garis zig-zag. Perbedaan antara keduanya tampak pada pemberian alasan yang berasal dari bukti itu sendiri. Hasil kajian mengindikasikan bahwa peran bukti dalam kelas matematika pada tingkat perguruan tinggi adalah membuktikan/meyakinkan, pada tingkat menengah atas adalah membuktikan dan menjelaskan, dan pada tingkat sekolah menengah pertama dan dasar peran utamanya adalah menjelaskan. Akibatnya bukti matematis tidak hanya membuktikan/menyakinkan, melainkan juga menjelaskan. Karenanya penting mempertimbangkan implikasi bukti dalam kurikulum matematika di sekolah, serta perlunya menyajikan bab materi kepada mahasiswa pendidikan matematika tidak hanya bukti yang membuktikan, melainkan juga bukti yang menjelaskan.Proofs that Prove and Proofs that Explain in Mathematics ClassroomAbstractThe purpose of this study was to comprehensively describe the differences of the proofs that prove and proofs that explain based on the consideration of the implications of the two proofs as the basis for the construction reasoning and proofs in mathematics. The study was undertaken with the activity of describing the specific differences between the two and providing examples of cases of both proofs; and provide justification for the importance of introducing both proofs in mathematics classrooms. Both proofs are illustrated by the problem of the odd number sequence concept. Proofs that prove is only shown using mathematical induction, while proofs that explain shows with Gaussian proof, a geometric representation of point shape, and zigzag line. The difference between the two appears to be the reasoning that comes from the proof itself. The results of the study indicate that the role of proof in mathematics classes at the tertiary level is proving/convincing, at the senior secondary level it is proving and explaining, and at the junior and elementary school level its main role is explaining. As a result, mathematical proof does not only prove/convince, but also explain. It is therefore important to consider the implications of proof in the mathematics curriculum in schools, as well as the need to present chapter materials to mathematics education students not only proofs that prove but also proof that explain.
