This study is experiment research with control group pretest-posttest design and aimed to examine the influence of PQ4R strategy and Refutation Text, school level, and student’s mathematical early knowledge toward achievement and enhancement of student’s mathematical communication ability and Self Regulated Learning. Subject of study as much as 241 students of class X from three Public Senior High School from high, medium, and low school level. Research instrument consist of one set of student’s mathematical communication, and one set of student’s Self Regulated Learning scale. Data analysis use Kosmogorov-Smirnov Test (Test-Z), Level Test, Test-t, one-way and two-way ANOVA, Post Hoc Test (Scheffe) and also Chi-Square Test. Study found that learning with PR4R strategy accompanied by Refutation Text Reading give consistent influence compared with conventional learning as viewed as a whole, based on school level and also mathematical early knowledge. In addition, study also found: (1) there is no interaction between learning (PQ4R) accompanied by Refutation Text reading and conventional and school level toward (a) student’s mathematical communication and (b) student’s Self Regulated Learning; (2) there is no significant interaction between learning and student’s mathematical early knowledge toward (a) student’s mathematical communication ability and (b) student’s Self Regulated Learning; and (3) there is association between student’s mathematical communication ability and student’s Self Regulated Learning.

Subyek penelitian sebanyak 18 orang toko masyarakat dari empat Kabupaten yang berbahasa Dayak Kanayat’n. Pengumpulan data dilakukan dengan menggunakan beberapa metode (Multi methods), yakni: pengamatan, studi dokumenter, diskusi kelompok terfokus, dan wawancara mendalam (indepth interview). Analisis data penelelitian dilakukan melalui pendekatan kualitatif. Data yang diperoleh dari wawancara mendalam, pengamatan, dokumentasi dan diskusi kelompok terfokus. Analisis dilakukan secara simultan dengan terlebih dahulu melakukan pemilahan data yang sejenis. Selanjutnya dilakukan reduksi data, penyajian, dan kesimpulan serta verifikasi. Berdasarkan analisis data ditemukan berbagai jenis kegiatan, sastra lisan, artifak-artifak, permainan tradisional, budaya menghitung dan mengukur di masyarakat Dayak Kanayat’n dapat dikembangkan dalam pembelajaran matematika di sekolah Kata Kunci: Etnomatematika, Dayak Kanayat’n, dan Budaya Loka

EFFECTIVITY OF PROBLEM BASED LEARNING (PBL) IN IMPROVING STUDENTS' MATHEMATICAL REPRESENTATION

Mathematical representation skill is one of the goals in mathematical instruction especially in high school as well as college. Multiple representation skill is the ability to present a mathematical object (problem, statement, solution, model, etc) into a variety of notation that include (1) symbolic (algebraic form and formula); it is used in manipulating, interpreting, and operating with symbols, (2) visual: to interpret , to create, and to operate mathematical object in graph or images, (3) numerical: this is used to apply the procedure, to understand and implement the process, and to interpret the table. This study examined the effect of problem based learning in representation skills of high school students. Experimental design with pretest-posttest was applied to obtain the effect with involving 42 high school students who were studying at the third grade. Multiple representations of mathematical tests were designed to get the data. Quantitative and qualitative methods were applied to analyze the data. The result shows that problem based learning is effective to enhance representation skill of students. Key Words: Problem Based Learning (PBL), Multiple Representations, and Effectivit

PENGEMBANGAN KEMAMPUAN KONEKSI MATEMATISSISWA MELALUI PENDEKATAN ADVOKASI DENGAN PENYAJIAN MASALAH OPEN-ENDED PADA PEMBELAJARAN MATEMATIKA

Penelitian ini merupakan penelitian eksperimen dengan disain pretes-postes kelompok kontrol dengan tujuan menelaah pengaruh pendekatan Advokasi dengan penyajian masalah Open-ended pada pembelajaran matematika terhadap kemampuan koneksi matematis siswa. Subyek penelitian sebanyak 80 siswakelas XIISMA. Instrumen penelitian terdiri dari satu set tes koneksi matematis siswa. Analisis data menggunakan, Uji X2, Uji Kosmogorov-Smirnov (Uji Z) uji Levene. dan Anava dua jalur.Hasil penelitian menemukan bahwa pembelajaran dengan pendekatan Advokasi dengan penyajian masalah Open-ended memberikan pengaruh konsisten dibandingkan dengan pengaruh pembelajaran konvensional.Selain itu, penelitian juga menemukan: (1) tidak terdapat interaksi antara pembelajaran pendekatan Advokasi dengan penyajian masalah Open-ended dan pengetahuan awal matematis siswa (PAM) terhadap kemampuan koneksi matematis siswa. (2) terdapatasosiasi antara kemampuan koneksi matematis siswa dan hasil belajar siswa. Kata-kata kunciPendekatan advokasi, Open-ended, dan koneksi matemati

PENGEMBANGAN MATHEMATICAL MAPLE BERBASIS KOOPERATIF THINK-PAIR-SHARE UNTUK MENINGKATKAN KEMAMPUAN REPRESENTASI MATEMATIS MAHASISWA DAN KUALITAS PERKULIAHAN FISIKA MATEMATIK

The main purpose of research is whether the representation of mathematical ability of students increased after learning gained through the program Mathematical Maple combined with cooperative learning Think Pair Share on lectures of Mathematical Physics. Subjects were students of third semester of physical education courses with the number of 35 students. The method used is a Class Action Research conducted through three cycles or actions which each cycle. The research instrument consists of: test, questionnaire, and observation guidelines. Based on data analysis concluded: (1) the ability of the representation of the students in understanding the meaning of the physical, the ability of representation of students to represent the mathematical equation in the form of graphs, the ability of the representation of the students in giving meaning physical on the results of visualization, and the ability of the representation of the students in understanding the course materials Mathematical Physics increase in each cycle or action; (2) the implementation process using computer-aided applications maple in the first cycle having problems because the students have never known the computer-assisted program maple, but in the next cycle students were able to adjust the maple program that is being used; and (3) the response of students to the course of action given the overall increase in each cycle.

REMEDIASI PEMAHAMAN KONSEP SISWA PADA MATERI SUHU DAN KALOR MENGGUNAKAN STRATEGI PDEODE DI SMA

Abstrak: Penelitian ini dilakukan untuk mengetahui pengaruh remediasi menggunakan strategi pembelajaran PDEODE terhadap peningkatan pemahaman konsep siswa pada materi suhu dan kalor. Metode yang digunakan dalam penelitian ini adalah Pre-Experimental dengan rancangan One-Group Pretest-Posttest. Pengumpulan data dilakukan dengan memberikan tes berbentuk esai yang terdiri dari 6 soal yang mewakili tiga proses kognitif Bloom yang telah direvisi kepada 29 siswa SMA kelas X. Berdasarkan hasil penelitian, rata-rata persentase peningkatan pemahaman konsep siswa untuk tiap proses yaitu membandingkan sebesar 24.14%, merangkum sebesar 6.89%, dan mengklasifikasikan sebesar 45.68%. selanjutnya, dengan taraf signifikansi (α) sebesar 5% diperoleh p = 0,000 dan Z = -4,729, hal ini menunjukkan bahwa strategi pembelajaran PDEODE berpengaruh terhadap peningkatan pemahaman konsep siswa. Adapun nilai efektifitas dari penelitian ini adalah 2.3 yang dihitung menggunakan Cohen’s Efffect size.   Kata kunci : Remediasi, Pemahaman Konsep, Strategi PDEODE Abstract: This research was conducted to determine the effect of remediation using PDEODE learning strategies to increase concept understanding of student on heat and temperature. This research used Pre-Experimental methode One-group pretest-posttest design. Data collecting was done by giving the test in the form of essay comprised 6 questions by representing three Bloom’s revisied cognitive process on understanding level. The test was administered to 29 grade 10th students. The result shows that the average percentage of increasing the student's concept understanding in each process are 24.14% for comparing, 6.89% for summarizing, and 45.68% for classifying. Furthermore, with a significance level (α) of 5% obtained p = 0.000 and Z = -4.729, this shows PDEODE learning strategy can affect to increase of student's understanding of concept and the effect size of this study is 2.3. It was calculated by using Cohen's Effect size. Keywords : remediation, concept understanding, strategi PDEOD
