Abstract

Geometri sebagai salah satu bidang kajian dalam materi matematika sekolah memperoleh porsi yang besar untuk dipelajari oleh siswa di sekolah. Dari distribusi penyebaran standar kompetensi untuk satuan pendidikan SMP, materi geometri mendapatkan porsi yang paling besar (41%) dibandingkan dengan materi lain seperti aljabar (29%), bilangan (18%), serta statistika dan peluang (12%). Namun demikian, penguasaan siswa dalam memahami konsep geometri masih rendah dan perlu ditingkatkan.Pengajaran geometri di sekolah diharapkan memberikan suatu sikap dan kebiasaan sistematik bagi siswa untuk bisa memberikan gambaran tentang hubungan-hubungan di antara bangun-bangun geometri serta penggolongan-penggolongan di antara bangun-bangun tersebut, untuk itu agar dalam pembelajaran geometri siswa dapat memvisualisasikan, menggambarkan, serta memperbandingkan bangun-bangun geometri dalam berbagai posisi, sehingga siswa dapat memahaminya dibutuhkan sebuah model pembelajaran berbasis software komputer dynamic geometry software yaitu GeoGebra. Dengan bantuan software ini siswa lebih memahami konsep-konsep dalam geometri. Pertimbangan tentang penggunaan dynamic geometry software seperti GeoGebra dalam pembelajaran matematika, khususnya geometri, diantaranya memungkinkan siswa untuk aktif dalam membangun pemahaman geometri.Pembelajaran geometri berbasis GeoGebra pada proses pembelajaran terbukti secara signifikan dapat meningkatkan kemampuan komunikasi matematis siswa, selaian itu sikap kritis dan kreatif selama pembelajaran ditunjukkan siswa. Peningkatan kemampuan komunikasi matematis siswa yang mendapat pembelajaran geometri berbasis GeoGebra berada pada kategori sedang. Hal ini menunjukkan bahwa siswa telah mengalami peningkatan kemampuan komunikasi matematis lebih baik dibandingkan hasil sebelumnya.

Abstract

Meningkatkan kemampuan komunikasi matematis sejalan dengan paradigma baru pembelajaran matematika. Berdasarkan pra survey penulis melakukan wawancara dengan salah satu guru matematika kelas VIII  MTs Negeri 2 Bandar Lampung dan guru tersebut mengatakan bahwa dalam proses pembelajaran  masih melakukan pembelajaran yang bersifat ekspositoris atau yang berpusat pada guru. Peserta didik terlihat kurang aktif, cenderung mendengar atau mencatat yang disampaikan oleh guru sehingga pembelajaran hanya berjalan satu arah saja. Keadaan ini sangat memperlihatkan bahwa kemampuan pemahaman konsep dan komunikasi peserta didik masih rendah. Dengan standar kriteria ketuntasan minimum (KKM) yaitu sebesar ≥ 70, hanya 8 dari 26 siswa kelas VIIIA yang tuntas dan 8 dari 25 siswa kelas VIIIB yang tuntas. Hal ini dapat disebabkan oleh rendahnya kemampuan pemahaman matematis peserta didik dan komunikasi matematis peserta didik dalam proses pembelajaran yang belum berjalan dengan baik. Penelitian ini bertujuan untuk melihat pengaruh pembelajaran dengan strategi heuristic vee terhadap kemampuan pemahaman konsep matematis peserta didik kelas VIII MTs Negeri 2 Bandar Lampung.Metode penilitan ini menggunakan posttest-only design. Hasil penelitian menunjukkan bahwa terdapat pengaruh pembelajaran dengan strategi pembelajaran heuristic vee terhadap kemampuan pemahaman konsep matematis peserta didikkelas VIII MTs Negeri 2 Bandar Lampung. Hal ini juga terlihat pada hasil belajar matematika siswa yang diterapkan pembelajaran dengan menggunakan strategipembelajaran  Heuristic Vee lebih tinggi dari pada rata-rata hasil belajar matematika yang tidak menggunakan strategi pembelajaran  Heuristic Vee.

Abstract

The phenomenon that occurs in students is the difficulty of them in detailing and sorting out the division of inheritance. In Islam everything is set up but its application in daily life has not been done with that should be. After the authors delve deeper into this material is indeed difficult to understand, especially in the details of each received by the heirs very closely related to the learning of mathematics in sub-material fractions. Lack of time allocation used in this material, resulting in them not getting examples of varied questions. The method used is qualitative descriptive method. This method tries to describe and interpret what is in accordance with the growing conditions in the ongoing process. Based on the phenomenon that occurred in the field can be concluded that the difficulties experienced by students is to determine the parts that must be accepted by the heirs that have been set in the Qur'an difficult to apply in everyday life, Islam has set clearly in the Qur'an But this has not been done properly. Another difficulty is also experienced in the learning of mathematics is on the equalization pemyebut of fractions obtained by heirs who are too many are entitled to receive inheritance.Keywords:

Abstract

SMPN 1 Batanghariin the second semester of the academic year 2012/2013.  They were two students who had field dependence cognitive style and two students who had field independence cognitive style. The subjects were taken by using the purposive sampling technique. The data of this research were gathered through think aloud method. The data were then analyzed by using the technique with the procedureas follows: (1) the data were classified on the basis of the indicators of mathematical communication after the data had been obtained from the first and the second collections; (2) the data were presented in table form; and (3) the conclusions were drawn. The validity of the data was conducted by using time triangulation. The result of this research were analyzed by using constant comparison in which subject in i (i= 1, 2) with the j (j= 1, 2) cognitive style which was already valid as well compared with subject in k (k= 1, 2) with the the j (j= 1, 2) cognitive style which was already valid as well. The equal ability of mathematical communication was made the main finding wheares the different ability of mathematical communication was made the other finding. The result of this research valid because of the dependability proved. The ability of mathematical communication of the students with the field dependence cognitive style is different from that of those with the field independence cognitive style. The students with the field dependence cognitive style can communicate the ideas in written way well but they have difficulties in communicating ideas in spoken way as well as inclination to receive information without reorganizing it in such a way that the problem-solving ideas presented cannot reveal the actual problem solution. Meanwhile, the students with the field independence cognitive style can communicate the ideas well in both spoken and written ways and process as well as reorganize information in such a way that the problem-solving ideas presented can reveal the actual problem solution.
