Abstract

This study is a quasi-experimental nonrandomized pretest-posttest control group design. The experiment group is treated by APOS theory instruction (APOS),that implements four characteristics of APOS theory, (1) mathematical knowledge was constructed through mental construction: actions, processes, objects, and organizing these in schemas, (2) using computer, (3) using cooperative learning groups, and (4) using ACE teaching cycle (activities, class discussion, and exercise). The control group is treated by conventional/traditional mathematics instruction (TRAD). The main purpose of this study is to analyze about achievement in proof. 180 students from two different universities (two classes at the Department of Mathematics UNAND and two classes atthe Department of Mathematics Education UNP PADANG) were engaged as the research subjects. Based on the result of data analysis, the main result of this study is that the proof ability of students' in the APOS group is significantly better than student in TRAD group, so it is strongly suggested to apply APOS theory in Abstract Algebra course.DOA : http://dx.doi.org/10.22342/jims.13.1.80.133-148

Abstract

The ability to solve problems is one of the important goals of mathematics. In order for problem-solving ability to flourish well, the learning should actively involve students. Student learning activity class VIII SMPN 5 Kerinci is still low, resulting in the ability to solve math problems is also low. One reason is the use of learning metodees that are still focused on teachers and do not actively engage students. For that purpose, efforts are made to improve students' maturity and problem solving abilities through Think-Talk-Write learning strategy. This research is a classroom action research conducted in two cycles. The subjects of the study were students of class VIII SMPN 5 Kerinci Pelajarair Year 2015/2016 which amounted to 22 people. The results showed that the learning by using TTW learning strategy can improve the activity and problem solving ability of student math. For listening activities, paying attention to teacher explanations, asking questions, reading, understanding LKS and making important notes, interactions in discussions, and staying in groups achieve both criteria and excellent criteria for individual LKS completion activities.

Abstract

Problem solving ability is one of the mathematical abilities that are important in the success of students. But the fact remains low problem solving ability. One model that can develop problem solving ability is the Problem Based Learning (PBL). RPP is one important component in learning. RPP used by teachers not specifically describe the learning process, as well as yet to be seen developing students' problem solving abilities. This study aims to determine the validity of PBL based lesson plans. The study consisted of a preliminary analysis phase, development, and assessment using the model of Plomp. However, this study is only done up to the stage of development that the validity of the stage. The instrument used in this study of guidance interviews, checklists, questionnaires, evaluation sheets and sheets validas experts themselves. The results of the validation sheet analysis showed RPP developed are valid with an average of validity index of 0.96.

Abstract

Using Mathematics Student Worksheet (LKS) which is made by teachers before hasn’t been effective to help students in learning process. Therefore, the mathematics LKS needs to be developed to help students to find the concept themselves. Sequence and series material is important in mathematics at Vocational High School (SMK), and yet students still find difficulty to understand it. The aim of this development is to produce mathematics LKS based on contextual approach which is valid, practical and effective. This development research uses a formative evaluation model by Tjeerd Plomp. The subject of the research is the second year students of SMKN 6 Padang. Validation is done by experts / lecturers. The practicality of LKS is seen from the observation of the implementation of learning, practicality questionnaires, and interviews conducted with students and teachers. Effectiveness is seen from the results of activities and student learning outcomes.

Abstract

Penelitian ini bertujuan mendeskripsikan ada atau tidaknya perbedaan kemampuan komunikasi matematis (KKM) antara siswa yang diajar menggunakan model pembelajaran kooperatif tipe Numbered Heads Together (NHT) dengan siswa yang diajar menggunakan model pembelajaran konvensional ditinjau dari tingkat kemampuan awal siswa yaitu tinggi, sedang, dan  rendah pada siswa Kelas VIII SMP Negeri di Kota Pekanbaru. Jenis penelitian ini adalah eksperimen semu  dengan rancangan posttest-only control group design. Jumlah sampel sebanyak 125 orang diambil secara acak dan bertingkat masing-masing 61 siswa dari sekolah percontohan dan 64 siswa dari sekolah non percontohan. Instrumen utama yang digunakan dalam penelitian ini adalah dua tes KKM yaitu tes KKM1 dan tes KKM2, kedua tes telah melalui proses validasi dan ujicoba dengan koefisien reliabilitas masing-masing 0,67 dan 0,66. Uji Mann-Witney digunakan untuk menganalisis ada atau tidaknya perbedaan rata-rata KKM antar kelas eksperimen dengan kelas kontrol pada masing-masing tingkat kemampuan awal siswa dan ANAVA 2 arah digunakan untuk menganalisis ada atau tidaknya interaksi antara faktor model pembelajaran dengan faktor  kemampuan awal. Hasil penelitian ini menunjukkan bahwa: (1) KKM siswa pada kelas eksperimen lebih tinggi secara signifikan jika dibandingkan dengan siswa pada kelas kontrol; (2) Pada siswa dengan tingkat pengetahuan awal tinggi dan sedang, KKM siswa kelas eksperimen lebih tinggi secara signifikan jika dibandingkan dengan siswa pada kelas kontrol; (3) tidak terdapat interaksi antara faktor model pembelajaran dengan faktor kemampuan awal terhadap kemampuan komunikasi matematis.  This research aims to determine if there are any differences in mathematical communication skills between students taught using Numbered Heads Together (NHT) cooperative learning model with students who are taught using conventional learning models are reviewed by the students' prior knowledge (high, moderate, and low) in class VIII of SMP Negeri in Pekanbaru City. This type of research is quasi-experimentation with posttest-only control group design. Number of samples as much as 125 students taken randomly and stratified  respectively 61 students from excelent school and 64 students from non excelent  school. The main instruments used is a mathematical communication skill (CCS) i.e.CCS1 and CCS2 test, both tests have been through the process of validation and testing with reliability coefficients respectively 0.67 and 0.66. The Mann-Witney test is used to see if there is an average difference in CCS  between experiments and control class at each the prior knowledge levels and the 2-way ANAVA is used to see if there the interaction between learning model variables and the prior knowledge variables. The results of this study showed that: (1) Students' CCS in the experimental class are significantly higher when compared to students in the control class; (2) Students' CCS in the experimental class are significantly higher when compared to students in the control class either at the high or moderate prior knowledge levels; (3) There is no interaction between the learning model and the prior knowledge toward CCS.
