Abstract

Penelitian ini bertujuan untuk (1) mendeskripsikan kemampuan literasi matematis dan self-efficacy siswa kelas XI SMA; (2) mendeskripsikan dampak perbedaan kebijakan sistem zonasi terhadap kemampuan literasi matematis dan self-efficacy siswa kelas XI SMA; dan (3) mendes­kripsikan hubungan antara literasi matematis dan self-efficacy siswa kelas XI SMA. Penelitian survei ini melibatkan 346 siswa dari Kota Banjarmasin dan 321 siswa dari Kota Palangka Raya. Kedua kota tersebut memiliki kebijakan zonasi yang berbeda. Pengumpulan data dila­kukan me­lalui tes dan angket yang telah memenuhi kriteria valid dan reliabel. Teknik analisis data yang digunakan adalah statistik deskriptif dan inferensial. Hasil penelitian menunjukkan bahwa literasi matematis siswa di Kota Banjarmasin dan Kota Palangka Raya berada pada kategori ren­dah, sedangkan self-efficacy siswa pada kedua kota berada pada kategori sedang. Tidak terdapat per­bedaan yang bermakna pada rata-rata literasi matematis antara siswa di Kota Banjarmasin dan Palangka Raya. Namun demikian, terdapat perbedaan yang bermakna pada rata-rata self-effi­cacy antara siswa di Kota Banjarmasin dan Palangka Raya. Kebijakan zonasi di Kota Palangka Raya menyebabkan perbedaan rata-rata literasi matematis siswa pada sekolah kategori tinggi, sedang, dan rendah. Sedangkan kebijakan zonasi di Kota Banjarmasin menyebabkan perbedaan rata-rata self-efficacy siswa pada sekolah kategori tinggi, sedang, dan rendah. Terakhir, terdapat korelasi positif yang signifikan (meskipun lemah) antara literasi matematis dan self-efficacy siswa kelas XI SMA di Kota Banjarmasin dan Kota Palangka Raya (r = 0,194). Mathematical literacy and self-efficacy of students in terms of differences in zoning system policies.AbstractThis study aimed to (1) describe the mathematical literacy abilities and self-efficacy of eleventh-grade senior high school students; (2) describe the impact of differences in zoning system policies on the mathematical literacy and self-efficacy of eleventh-grade senior high school students; and (3) describe the relationship between mathematical literacy and self-efficacy of eleventh-grade senior high school students. This survey involved 346 students from Banjarmasin City and 321 students from Palangka Raya City, Indonesia. The two cities have different zoning policies. The data was collected through tests and questionnaires that met the valid and reliable criteria. The data analysis technique used was descriptive and inferential statistics. The results showed that students’ mathematical literacy in Banjarmasin and Palangka Raya City was in a low category, while self-efficacy in both cities was in the medium category. There was no significant difference in the mean of mathematical literacy of students in Banjarmasin and Palangka Raya City. How­ever, there was a significant difference in the mean of self-efficacy of students in Banjar­masin and Palangka Raya City. The zoning policy in Palangka Raya City causes differences in the mean of mathematical literacy of students in high, moderate, and low category schools. In contrast, the zoning policy in Banjarmasin City causes differences in the mean of self-efficacy of students in high, medium, and low category schools. Lastly, there was a significant positive correlation (al­though weak) between mathematical literacy and self-efficacy of eleventh-grade senior high school students in Banjarmasin and Palangka Raya City (r = 0.194).

Abstract

This study aims to describe the difference in creativity and mathematics achievement between gifted students who were taught by Treffinger's learning and those who thought by the expository learning in trigonometry material. This study is a quasi-experiment using a pretest-posttest group design with a population of all gifted students in class X of a State Senior High School in Bali, Indonesia. The sample was established randomly. Observation sheets, pre-test, post-test, and student creativity questionnaires were used, all of which have been validated. The data were analyzed descriptively and inferentially with the paired sample t-test to test the mean difference of the pre-test and post-test data. The results show that the average creativity of students in the experimental class is significantly higher by 9.46 points than that of the control class. In terms of mathematics learning achievement, the average gain score in the experimental class increased significantly by 58.365 points. It can be concluded that Treffinger’s learning is effective in increasing creativity and mathematics achievement of gifted students in trigonometry material.
