Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan metakognitif siswa dengan kemampuan akademik yang tinggi, sedang, dan rendah untuk memecahkan masalah matematika pada siswa kelas XI MAN Panyabungan. Penelitian ini dilakukan dengan menerapkan metode deskriptif kualitatif. Informan penelitian adalah kepala sekolah, guru matematika, dan 15 siswa yang diambil dengan menggunakan teknik purposive sampling. Teknik pengumpulan data menggunakan catatan lapangan, tes, wawancara, dan dokumentasi dan analisis data dilakukan dengan menggunakan reduksi, penyajian data dan kesimpulan. Hasil penelitian menunjukkan (1) siswa yang memiliki kemampuan matematika tinggi memiliki pemecahan masalah matematika yang sangat baik (metakognitif strategic use), (2) siswa yang memiliki kemampuan matematika sedang memiliki pemecahan masalah matematis yang baik (metakognitif aware use), dan ( 3) siswa yang memiliki kemampuan matematika rendah memiliki cukup pemecahan masalah matematika (metakognitif tacit use).

Abstract

The aims of this study is to: 1) describe of using inside outside circle learning model, 2) describe students’ mathematic communication ability before and after using inside outside circle learning model, and 3) describe effectiveness of using inside outside circle learning model on students’ mathematic communication ability at the seventh grade students SMP Negeri 1 Tantom Angkola. This research was conducted by applying experimental method (one group pretest post test design) with sample 30 students and they were taken by using simple random sampling technique. Observation and test were used in collecting the data. Based on descriptive analysis, it was found that: (a) the score of using inside outside circle learning model was 3.9 (very good category), b) the average of students’ mathematic communication ability before using inside outside circle learning model was 33.13 (fair category) and after using inside outside circle learning model was 84.40 (very good category), significant value was 0.00<0.05, and c) N-Gain value was 0.76 (high category), inside outside circle learning model was effective which had percentage 66.7% (effective criteria). It was concluded inside outside circle learning model increased students’ mathematic communication ability at the seventh grade students SMP Negeri 1 Tantom Angkola.

Abstract

Abstract This study aims to know whether there is a significant effectiveness of using Think Pair Share (TPS) learning model on students’ mathematical problem solving ability on the topic of solid at the eighth grade students of Ponpes Al-Mukhtariyyah Sungai Dua Portibi. The research was conducted by applying experimental method (one group pretest post test design) with 42 students as the sample and they were taken by using simple random sampling technique from 128 students. Observation and test were used in collecting the data. Based on descriptive analysis, it could be found (a) the average of using TPS learning model was 3,33 (very good category) and (b) the average of students’ mathematical problem solving ability on the topic of solid before using TPS learning model was 61.65 (enough category) and after using TPS learning model was 79.66 (good category). Furthermore, based on inferential statistic by using pair sample ttest, (SPSS version 20),the result showed the significant value was less than 0.05 (0.000<0.05). It means, there is a significant effectiveness of using Think Pair Share (TPS) learning model on students’ mathematical problem solving ability on the topic of solid at the eighth grade students of Ponpes Al-Mukhtariyyah Sungai Dua Portibi. Keywords: TPS learning model, on students’ mathematical problem solving ability

Abstract

This study aims to determine the students' mathematical understanding ability, early ability students with early ability high, medium, and moderate initial abilities in the 3rd semester entrepreneurship of program study students. The improvement of students' mathematical understanding skills is carried out using a problem-based learning model. This research was carried out by applying the Qualitative Research method. Informants in this study were the Head of the Study Program and students who were taken using the Total Sampling technique. Data collection techniques used field notes, tests, interviews, and documentation. Data analysis was performed using data reduction. The results showed (1) students who had high early mathematical abilities had very good mathematical understanding abilities, (2) students who had moderate early mathematical abilities had good mathematical understanding abilities, and (3) students who had low mathematical abilities had low mathematical abilities sufficient mathematical understanding.

Abstract

Education aims to create quality human resources and be able to carry out the goals of education and one of them is the ability to solve mathematical problems. This type of research is descriptive research by carrying out a literature review of 10 journals. Based on the review conducted, it was concluded that abilities are very important for every student, teacher, and facilitator to have. Problem solving abilities can also collaborate with self-confidence, self-creativity, and innovation in improving academic achievement and enhancing future careers.
