Abstract

Proses pembelajaran  matematika di kelas merupakan salah satu  penentu keberhasilan peserta didik. Guru dituntut untuk memberikan inovasi baru dalam proses belajar mengajar, misalnya dalam memilih model, metode atau strategi pembelajaran yang tepat digunakan. Salah satu metode pembelajaran yang bisa digunakan adalah hypnoteaching. Hypnoteaching berasal dari dua kata hypno dan teaching. Hypnoteaching merupakan metode pembelajaran yang kreatif , unik dan imajinatif. Sebeum pelaksanaan pembelajaran peserta didik sudah dikondidikan untuk belajar. Dengan demikian, peeserta didik mengikuti proses belajar dalam kondidi segar dan siap untuk menerima materi pelajaran. Untuk mempersiapkan hal-hal tersebut, tentu guru itu sendiri dituntut untuk stabil baik secara psikis maupun psikologis. Pelatihan metode hypnoteaching ini bertujuan agar guru lebih mengenal apa itu hypnoteaching sehingga guru dapat menerapkannya dalam pembelajaran matematika di kelas. Dari hasil pelaksanaan secara umum pelatihan pembelajaran matematika yang efektif melalui metode Hypnoteaching empat tahap: 1) Matematika itu mudah, 2) Matematika dengan Benda Konkrit Sederhana, 3) Matematika Itu Menyenangkan, 4) Operasi Hitung Matematika, 5) Menjadi Guru Inspiratif Berbasis Hipnosis.

Abstract

This research is a preliminary study that aims to describe the algebraic thinking process of prospective mathematics teachers. This research is a qualitative descriptive study. Subjects were grouped into two categories based on high and low achievement motivation. Data is obtained based on the results of tests conducted in the algebra process. Research subjects (S1) and (S2) with high achievement motivation and subjects (S3) and (S4) with low achievement motivation using different algebraic thought processes. Subjects (S1) are able in the process of thinking algebra until crashing indicators assess understanding with understanding of the concept wrong in solving Higher Order Thinking Skills (HOTS) problems, whereas, (S2) the process of thinking algebra is only capable of chunking information (pieces of information), (S3) able in the process of thinking algebra until indicators of change with wrong answers, and the subject (S4) is able in the process of thinking algebra only until chunking information (pieces of information). Factors that cause subjects S1, S2, S3, and S4 are still unable to solve HOTS questions in algebraic thinking processes are questions of knowledge on HOTS material and difficulty understanding concepts in working on algebra need special handling in improving understanding of concepts in algebra.

Abstract

Abstract : This study was aimed to define profile of mathematical communication based on the level of problem solving ability on secondary students. This study used mixed methods model with explanatory type. This sample used 30 secondary school students who was chosen based on teachers? recommendation. The result shown that there are 16,67% students whose problem solving?s ability  were placed on low level If we look on mathematical communication ability?s side, most of students faced on the diffulties of projecting figures into mathematical ideas. Students still made mistakes on calculating and the indicators was difficult when it stated to project any figures into mathematical ideas while the indicator that appear frequently was stated events or ideas in mathematical laguage. There are 70% students that whose problem solving ability were placed on medium level. If we look on mathematical conection ability most of information as shown unclearly and faced on difficulties when they summarize conclusion, they stated it into mathematical symbol. There are 13,33% students whose problem solving ability were pleced on high level and unclear to every single information that was told within solving strategy which directly on solving essentials. Keywords: Profile of mathematical Ability, Mathematical Communication, Problem Solving

Abstract

Higher-order thinking skills (HOTS) merupakan tahapan taksonomi Bloom paling tinggi yaitu analisis (C4), menilai (C5), dan kreasi (C6). Penelitian ini bertujuan untuk mengidentifikasi hambatan mahasiswa calon guru matematika dalam  menyelesaikan masalah bermuatan HOTS dan faktor penyebabnya. Penelitian ini menggunakan metode kualitatif. Pengumpulan data adalah tes yang digunakan untuk mengidentifikasi hambatan belajar. Instrumen yang digunakan adalah peneliti sebagai instrumen utama, instrument soal HOTS, kuisioner terbukaterkait hambatan belajar. Subjek penelitian terdiri dari 118 orang mahasiswa Pendidikan Matematika Semester ganjil dengan perwakilan tiap 1 kelas pada semester 1,3,5, dan 7 pada salah satu Universitas Muhammadiyah di Jakarta Timur yang dipilih dengan teknik purposive sampling. Hasil dari penelitian ini adalah terdapat tiga tipe hambatan belajar mahasiswa calon guru dalam menyelesaikan masalah bermuatan HOTS diantaranya  (1) tipe 1 terkait konsep-konsep materi persamaan 4 variabel dan bilangan asli pada indikator kemampuan dalam menganalisis (C4) dan kreasi (C6); (2) tipe 2 terkait prosedur penyelesaian soal operasi aljabar, akar dan pecahan dalam bentuk irrasional pada indikator menganalisis (C4), Menilai (C5) dan kreasi (C6); (3) tipe 3 terkait hubungan materi matematika dengan konsep matematika yang lain yaitu geometri dengan trigonometri dan geometri dengan lingkaran pada indikator kemampuan dalam menilai (C5) dan kreasi (C6); Faktor yang menyebabkan mahasiswa calon guru matematika masih lemah dalam menyelesaikan masalah bermuatan HOTS adalah ketidakbiasaan mahasiswa dalam menyelesaikan masalah soal HOTS dan ketidakberkembangnya kemampuan berpikir tingkat tinggi siswa dalam menyelesaikan masalah. AbstractHigh-order thinking skills (HOTS) are the highest stages of Bloom's taxonomy, namely analysis (C4), assessing (C5), and creating (C6). This study aims to identify the barriers of pre-services in solving HOTS-laden problems and their causes. This study uses a qualitative method. Data collection is a test used to identify learning barriers. The instrument used was the researcher as the main instrument, the HOTS question instrument, the open questionnaire related to learning obstacles. The research subjects consisted of 118 odd semesters Mathematics Education students with representatives for 1 class in semester 1,3,5 and 7 at one of the Muhammadiyah Universities in East Jakarta. They were selected by purposive sampling technique. The results of this study are that there are three types of pre-services obstacles in solving HOTS-loaded problems, including (1) type 1 related to the material concepts of the four variable equations and real numbers on the indicators of ability to analyze (C4) and creation (C6); (2) type 2 related to problem-solving solutions of algebra, roots, and fractions in the irrational form on indicators (C4), Assess (C5), and creation (C6); (3) type 3 relation between mathematics material and other mathematical concepts, namely geometry with trigonometry and geometry with circles on the indicators of ability in assessment (C5) and creation (C6); The factors that cause student mathematics teacher candidates to be weak in solving HOTS-laden problems are students' unfamiliarity with solving HOTS problems and not developing high-order thinking skills in solving problems.
