Pengembangan Disposisi Matematis Siswa Difable melalui Model Pembelajaran Active Learning di Sekolah Menengah Atas Luar Biasa

The purpose of this research generally to obtain accurate information related to the development of students' mathematical disposition difable in mathematics learning in class XI High School Second Half Superb Dharma Asih South Pontianak. The method used is descriptive. With active learning models and mathematical disposition questionnaire as a measurement of the disposition developments, conducted this research by providing a questionnaire beginning and end of the learning process takes place during the three meetings. From the research that then there is the development of students' mathematical disposition difable the average initial questionnaire 0.47 and the average questionnaire finally 0.82. Thus the average score of students' mathematical disposition difable progression from lower category to be good

Kemampuan Pemecahan Masalah pada Materi Trigonometri Dikaji dari Self Concept Siswa Kelas XI IPA

The research aims to describe the problem-solving ability on the materials about trigonometry of students' self concept in SMA Kemala Bhayangkari 1 Kubu Raya eleven grade. The method is used descriptive method with case study of research. The sample of research was 9 students. The sample determination is done by taking 3 students who have high self concept, 3 students who have average self concept, and 3 students who have low self concept. The results of data analysis showed tha the problem-solving ability on the materials about trigonometry for students who have high self concept is very good, problem-solving ability on the materials about trigonometry for students who have average self concept is good, and problem-solving ability on the materials about trigonometry for students who have low self concept is good sufficient

Penerapan Pembelajaran Kooperatif Berbantuan Alternative Solutions Worksheet untuk Meningkatkan Kemampuan Pemecahan Masalah Matematis Siswa

This study aims to increase mathematical problem solving ability of students in rectangular of matter in class VII MTs. Darul Amin Pontianak. The method used is Quasi-Experimental Design with the study design Posttest Only Control Group Design. The study sample is 44 students. The result of the t test obtained value the Sig. (2-tailed) = 0.006 <α = 0.05 which means that on average there is a difference between the mathematical problem solving ability of students who were given a cooperative learning aided alternative solutions worksheet (ASW) and students who were given a direct learning aided ASW. The result of normalized gain calculations, obtained a value of 0,59, which means there is an increased problem solving ability of student after application cooperative learning aided ASW . The result of Size Effect calculations, obtained a value of 2,89, which means using the cooperative learning aided ASW provide the highest contribution to the mathematical problem solving ability of student

Increasing Motivation and Achievement of Student Learning through Homework Accompanied Feedback. This research to know how big improvement of motivation and achievement of student in studying math through learning process in form of giving homework accompanied feedback in SMPN 1 Tujuh Belas school years 2011/2012. Research method which is use in classroom action researchconsist of two cycles. Research subject is eighth grade students of SMPN 1 Tujuh Belas school years 2011/2012. Based on data analysis obtained result of research :(1) Applying study through homework accompanied feedback can increase students motivation in learning of eighth grade students of SMPN 1 Tujuh Belas equal to 33,34% from only 57,57 % highly motivated student and very height after cycle I becomes 90,91 % highly motivated student and very height after cycle II,(2) Applying homework and feedback can increase achievement of student learning 11,27 or 20,23 % out of 55,71 after cycle I becomes 66,98 at cycle II.(3) Applying homework giving feedback also can increase number of complete studentsinlearning 9,09 % out of 57,59 % out of 33 students after cycle I becomes 66,67 % as of cycle after II

Model Pembelajaran Ttw dan Tps terhadap Kemampuan Komunikasi Matematis Siswa dalam Materi Bangun Datar

This research aims to compare the cooperative learning model type Think Talk Write (TTW) and Think Pair Share (TPS) of students' mathematical communication ability on plane matery in seventh grade of SMP Negeri 1 Semparuk. The research used experimental method with pretest-posttest control group Design. This sample in this research is 34 students of class VII B and 33 students of class VII C. Samples were determined by simple random sampling technique. Analyzed of data using gain scores analyzed. Results analyzed showed that increasing students' mathematical communication abilities after learning with TTW the average index of gain is 0.32 and with TPS is 0.37. For analyzed of student responses using a Likert scale calculations. Results calculations showed contained 77% gave a high response to learning TTW and 94% gave a high response to learning TPS. This illustrates that students' mathematical communication abilities on learning mathematical TTW lower than TPS
