Abstract

Tujuan dari penelitian ini adalah mengembangkan produk berupa bahan ajar matematika berbasis etnomatematika yang valid, praktis, dan efektif. Penelitian ini merupakan penelitian dan pengembangan (RD) dengan menggunakan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Subjek penelitian ini adalah peserta didik kelas XI Mia 2 SMA N 1 Purbolinggo. Instrumen yang digunakan untuk mengumpulkan data berupa angket validasi oleh ahli, angket respon peserta didik dan tes hasil belajar. Hasil analisis validasi Bahan Ajar Matematika Berbasis Etnomatematika adalah 88% masuk dalam kriteria valid, rata-rata hasil penilaian/respon peserta didik adalah 80% yang masuk dalam kategori sangat kuat/respon positif, dan ketuntasan klasikal peserta didik mencapai 86%. Berdasarkan analisis tersebut dapat disimpulkan bahwa bahan ajar matematika berbasis etnomatematika yang dikembangkan valid, praktis, dan efektif.

Abstract

The purpose of this study to describe the error and to know the cause of student error in solving trigonometric problems based on Newman Theory and cognitive style. The type of this research is qualitative descriptive research conducted at SMAN 1 Sekampung Udik. Selection of research subjects using purposive sampling, selected 4 research subjects with 2 subjects have a cognitive style reflective and 2 subjects have impulsive cognitive style. Data collection techniques used were tests and interviews, while the instruments used were: (1) cognitive style test or MFFT (Matching Familiar Figure Test), (2) trigonometric problem test, and (3) interview guides.    The results of this study can be described as follows. (1) students who have reflective cognitive style in solving trigonometric problems tend to make mistakes in the stage of transformation error and process skill error; and encoding error, (2) where as students who have impulsive cognitive style in solving trigonometric problems tend to make mistakes in the phase of comprehension error, transformation error, process skill error and encoding error. (3) The cause of the errors of cognitive and relative impulsive cognitive students are the students can not understand the problem well, forget the formula, less thorough in solving problems, rush in solving problems, not used to write conclusions, and run out of time in solving problems DOI: http://dx.doi.org/10.23960/mtk/v8i2.pp89-99

Abstract

The purpose of this research is to improve students mathematics learning outcome through Problem Based Learning (PBL) with QR-Code on MIPA class grade X SMA Negeri 1 Kotagajah (Senior High School in Kotagajah). This research is an Action Research Class. The subject of this research is 36 Students. This research is cyclus research with Kemmis and Mc Taggart Models consisting of: (1) planning; (2) implementation; (3 observation; and (4) reflection. Data collection technique is using in this research is tes. Based on the research result, then obtained the conclusion is Problem Based Learning with QR-code can improve students mathematics learning outcome on MIPA Class grade X SMA Negeri 1 Kotagajah. This matter showed a percentage value on the first cyclus is 47,22% and increase on the second cyclus to be 63,89%.
