(3) Reliabilitas instrumen termasuk kategori cukup tinggi yang ditunjukkan dengan besarnya koefisien reliabilitas alpha yakni sebesar 0.8797. Kara kunci: instrumen kemandirian belajar mahasiswa
The character of responsibility is an important character that Indonesian students must possess. The attempts to strengthen the character of student responsibilities require in-depth information about the actual state of student's responsibility. The use of relevant, valid, and reliable instruments is necessary to obtain accurate and accountable information about the conditions of student's responsibility. A scale for measuring student's responsibility in mathematics learning was developed through this study. The scale was developed by using subject scaling models and tested on junior high school students in Yogyakarta, Indonesia. The first trial involved 688 students and a second trial involved 696 students. Based on this study, the result of Student's Responsibility Scale on Mathematics Learning (SRSML) consisted of 14 items in the form of subject scaling which theoretically and empirically proved to be of good quality. The scale has good content validity supported by V Aiken index of 0.88-0.92. The scale has good construct validity. Scale reliability is also categorized as good with Omega coefficient of 0.89. SRSML has a lot of potential to be used both in the character assessment activities of students in learning mathematics to strengthen character education and educational research, especially related to the student's responsibility character.
Purpose: Essay test in mathematics, both in the form of restricted-response and extended-response, generally consist of polytomous scored items. However, the essay test used by teachers in Indonesia has not been fully supported by sufficient quality evidence. There have been many studies focusing on the development of the essay test, but not many of them have applied the use of relevant measurement theory for the polytomous data. The evidence of content validity also has not been supported by its alignment with the curriculum. This study used alignment index to
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.
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).
