Kita tahu bahwa peningkatan kualitas peserta didik tak pernah bisa dilepaskan dari kualitas pendidiknya. Sebenarnya pemerintah Indonesia telah berusaha dengan keras meningkatkan kualitas pendidikan dengan cara meningkatkan mutu guru, peningkatan fasilitas dan perlengakapan pembelajaran, perbaikan kurikulum dan pengembangan penggunaan teknologi iinformasi untuk mendukung proses pembelajaran.

Kualitas proses pembelajaran sangat dekat hubungannya dengan apa yang guru lakukan di dalam kelas. Penelitian-penelitian yang telah dilakukan mengindikasikan bahwa gaya mengajar guru didominasi oleh metode eksposisi contohnya pada siklus pengajaran klasikal seperti menjelaskan konsep, memberikan contoh, memberikan pertanyaan, dan pada akhirnya memberikan tugas. Tingkah laku dan kompetensi guru secara langsung berpengaruh pada kemampuan guru dalam merencanakan dan mengatur waktu, untuk menyadari objek ajar, untuk mengatur kombinasi aktivitas kelas. Metode eksposisi masih bisa digunakan oleh para guru, tetapi hanya caranya saja yang sedikit berbeda. Eksposisi di sini hanyalah penjelasan singkat mengenai materi pelajaran, selebihnya adalah latihan soal dan juga problem solving. Pada kegiatan latihan soal dan juga problem solving, siswa dapat dibentuk menjadi kelompok diskusi. Setiap pengerjaan soal selesai semua hasil diskusi kelompok dapat dibicarakan seluruh kelas. Problem solving sangatlah berguna bagi para siswa, sehingga mereka bisa tahu keguanaan belajar matematika dalam kehidupan sehari-hari. Problem solving didefinisikan oleh Ebbutt dan Straker sebagi penggunanan pengetahuan matematika: memilih kemampuan yang tepat, penggunaan metode yang teapt dan mencari solusi dari problem yang ada.

Investigasi dan pengembangan praktek langsung di pengajaran memberikan guru kesempatan untuk meningkatkan metode pembelajaran di kelas. Langkah nyata yang dapat diambil oleh pengajar antara lain: meningkatkan kemampuan mengajar matematika agar dapat memfasilitasi kemampuan akademik siswa yang berbeda-beda (adanya LKS, diskusi, belajar kelompok, bimbingan personal siswa, dll), dan yang tidak kalah pentingnya adalah selalu mendorong siswanya untuk menjadi pembelajar yang aktif.

PENDEKATAN MATEMATIKA REALISTIK PADA PEMBELAJARAN PECAHAN DI SMP

By: Dr. Marsigit, M.A. Reviewed by: Kholida Agustin As we know, that realistic mathematics emphasizes to construct the context of concrete thing as first point (impression) for the student to get the concept of mathematics. The concrete thing is manipulated by the student to support the students’ effort in change the concrete thing to abstract one. The student need to given a chance so they can construct and product mathematics by their own language. The standard competence in junior high school that related with fraction learning has the aim to make the student understand about operation properties and how to use it to solve the problem. The development of realistic problem that related with the fraction form such as the fraction and its form, simple fraction, change the fraction that numerator bigger than denumerator become “campuran” fraction, compare the fraction, order the fraction, etc. Reflect from that activity so in the learning fraction by learning mathematics r...

KEGIATAN PENELITIAN SEBAGI USAHA UNTUK MENINGKATKAN PROFESIONALISME GURU MATEMATIKA

By: Dr. Marsigit, MA Reviewed by: Kholida Agustin   Research can be define as an activity to get knowledge, were done by certain procedures that systematically and support by methodology. Teacher as researcher can make a change in mathematics teaching learning in the school by various experiments, so it has result science method. Truthfully, contemporary mathematics education research is mathematics research education that the researcher have awareness about how important understanding truthfully of mathematics, mathematics in school, mathematics education, learn mathematics theory, etc. The view about the truth and mathematics character in school will give whole characteristic of mathematics. It has assumed that there are still many students that not like mathematics. There are some characteristics of mathematics such as: pure mathematics, applied mathematics and mathematics in school. In order to develop student competences, assumption about the student characterist...

MATHEMATICS TEACHING ACROSS MULTICULTURAL CONTEXT

By : Kholida Agustin (09301241011) Department of Mathematics Education, Faculty of Mathematics and Science, Yogyakarta State University A.     Introduction   A Mathematics still becomes scary subject for student. Improper teaching method that used by the teacher make student confuse and not have any desire to learn mathematics further. The students are prosecuted to always develop their knowledge and their ability in mathematics. On the other hand, the teacher also prosecuted to improve their teaching skill. There is opinion, “if we want to improve the student’s ability, we must improve the teacher skill first”. This opinion should be advice for the teacher to become better teacher in the future. Teaching mathematics in school should be has suit approaches to make the student improve correctly, suit with world development. The development of technology makes this world feel tighter. The student can learn by their selves by other friend or ...
