Abstract

The purpose of this research is to increase the interest and the result of learning mathematics class IX Junior High School Student Class IX Smp Taman Mature Ibu Pawiyatan through Learning Strategy Improving Thinking Ability (SPPKB).The results of this study indicate that after applied Learning Strategy Model of Improving Thinking Ability (SPPKB), interest and learning achievement of mathematics have increased. Student interest increased from cycle I of 64, 79% increased to 70,81% in cycle II. While the student's learning outcomes also experienced an increase. The average value of students from the initial ability of 50.33 with 5 students (16.67%) who meet the KKM increased to 55.90 with 9 students (30.00%) who meet the KKM on cycle I. While in cycle II the average score of students increased to 78.82 with 22 0rang students (73.33%) who meet the KKM in cycle II. Thus, it is suggested that teachers in learning mathematics is suggested to use Learning Strategy Model of Improvement of Thinking Ability (SPPKB) on other materials as an alternative to increase student's interest and learning achievement.

Abstract

This study aims to produce a learning trajectory using takraw teams context in helping students to understand the concept of combinations. This research used design research to give in developing local instructional theory in learning combinations. Learning trajectory designed in the early phases and tested on 36 tenth-grade students in SMA N 15 Palembang. This result is a learning trajectory  which consists of 3 activities using takraw teams context:1) student do role-play scene of selecting main teams and handshake between players, this supports students to understanding in combinations order doesn’t matter. 2) students analyze the general pattern of combination with the knowledge of students about the factorial. 3) student solve problems related to combination helps students in thinking about how to solve a real-world problem related to combination. From the resulting activity can be concluded that learning to use takraw teams context can help students understand the concept of combinations.

Abstract

Penelitian ini bertujuan untuk menguji dan menganalisis perbedaan kemampuan pemecahan masalah matematis. Tujuan jangka panjang penelitian ini adalah (1) tersusunnya rencana perkuliahan yang dikembangkan dengan mempertimbangkan keragaman respon mahasiswa sehingga diharapkan dapat mengantisipasi keragaman lintasan belajar yang dilalui oleh masing-masing mahasiswa; (2) mengembangkan rencana pembelajaran dan bahan ajar materi geometri analitik berbasis model pengembangan bahan ajar tertentu sehingga diharapkan dapat membantu mahasiswa dalam memahami konsep-konsep esensial sehingga kebutuhan belajar mahasiswa terpenuhi. Metode penelitian yang akan digunakan adalah metode eksperimen, berbentuk quasi-exsperimental design (the static group pretest-posttest design). Dari populasi seluruh mahasiswa tingkat 2 yang mengikuti perkuliahan geometri analitik dipilih dua kelompok mahasiswa secara purposive sebagai sampel. Uji statistik yang akan digunakan untuk menguji hipotesis adalah independent sample t-test. Hasil penelitian menunjukan bahwa pemecahan masalah matematis mahasiswa yang pembealajarannya menggunalakan GI berbantuan geogebra lebih baik daripada pembelajaran konvensional.

Abstract

This study aims to find out the effectiveness of TAI model through mathematics learning outcomes in terms of students' student activity. This research was a quasi-experimental research. Sampling technique in this research used Cluster Random Sampling technique. Data collection technique used questionnaire and tests. The data analysis technique used two-way variance analysis with unequal cell. The result of this research was that learning using TAI model is not more effective to use (Fobs< Ftable) with 2.859 <4.00; Students who have high student activity, have mathematics learning outcomes that are no better than those with moderate and low-skilled students (Fobs< Ftable) with 0.5576 < 3.15; There is no interaction between the learning model used and the student activity to the students' mathematics learning outcomes (Fobs< Ftable= 0.44 <3.15). A suggestion on the results of this study is in the process of teaching and learning teachers should be able to create an atmosphere of learning that can make students become more active.
