Abstract

The educational achievement in Indonesia is measured by implementing the National Examination or Ujian Nasional (UN). Throughout its implementation, the UN results shown unsatisfying results, including in mathematics subjects. This fact indicated that there are mathematics topics that are considered to be difficult for students. This study aimed to investigate the difficult topics of mathematics in Vocational High School (VHS) based on UN data. This study was a descriptive research with the quantitative approach by using the UN report results in the level of VHS from Center for Educational Assessment of the Ministry of Education and Culture in the period of 2008 to 2017 (ten years) as a research data source. Data analysis was carried out in a quantitative descriptive by mapping the mathematics topics based on proportion correct answers or “daya serap”. A topic was considered difficult if the proportion correct answer was less than 50%. The results showed that there were 14 difficult mathematics topics in the UN implementation at the VHS level from 2008 to 2017. These topics include the comparison of trigonometric functions, solid figure, limit, measure of data dispersion, permutation and combination, differential, area between two curves, a measure of central data tendentious, probability, logarithm, integral, sequence and series, linear program, and polar coordinates system. The implications of the research findings for learning practice and future research opportunities are discussed.

Abstract

The unequal amount of questions that test students' lower and higher-order thinking skills is a concern in mathematics learning evaluation. The unequal amount of questions resulted in poor cognitive levels among students. The purpose of this study is to develop questions that may be used to assess the higher-order thinking skills of senior high school pupils and fulfill the requirements of being valid, practical, and effective. This study is a developmental research that employs the formative evaluation model. Validation sheets, student evaluation sheets, and examinations that measure students' higher-order thinking skills are among the data gathering procedures employed. According to the researchers' findings, the questions generated matched the valid, practical, and effective requirements. The valid criteria are based on the validators' assessments, and both validators agree that the questions created are good and possible to utilize with a few adjustments. Student answer papers to the established questions serve as the basis for practical criteria. According to the response form, 85 percent of pupils answered positively to the questions. Effective criteria are based on pupils' abilities to answer the questions that have been established. According to the test findings, 85 percent of students satisfied the minimal completeness requirements for both questions testing higher-order thinking skills, indicating that the questions were effective. The questions that have been developed by researchers can be used by teachers to evaluate students' higher-order thinking skills so that teachers do not only provide questions that measure students' lower-order thinking skills. In addition, the questions that have been developed can be used as a reference for developing questions that can measure students' higher-order thinking skills.

Abstract

Mathematical literacy and self-efficacy are critical in learning, especially mathematics. In contrast to previous studies, which only describe mathematical literacy and self-efficacy, this study aims to describe the ability of mathematical literacy in terms of mathematical self-efficacy. This research was a survey research qualitative and quantitative approaches. The results of this study indicate that the mathematical literacy abilities of grade VIII students in junior high school in Yogyakarta with sample 436 students are in a low category and the mathematical self-efficacy in the medium category. The higher the students’ mathematical self-efficacy, the higher their mathematical literacy. Students with high mathematical self-efficacy also tend to keep their maximum effort because they have the confidence to solve math literacy questions. Students with medium mathematical self-efficacy tend to doubt their abilities when facing difficult mathematical literacy questions. Students with low mathematical self-efficacy tend not to be confident in solving them because they think they lack mathematical abilities. This research is expected to map the mathematical literacy abilities of junior high school students in Yogyakarta. Besides, it can make material for reflection in world education to improve it.

Abstract

Tingginya pertumbuhan penduduk dapat mempengaruhi kepadatan penduduk. Jumlah penduduk cenderung meningkat setiap tahunnya terutama di Kabupaten Sleman salah satu kabupaten di Yogyakarta dengan jumlah  penduduk terbanyak. Peramalan jumlah penduduk sangat diperlukan karena data jumlah penduduk sering dijadikan sebagai dasar untuk perencanaan maupun sasaran pembangunan di waktu yang akan datang. Tujuan penelitian ini adalah untuk mendeskripsikan model yang cocok dalam peramalan jumlah penduduk pada tahun 2021 – 2023 dengan metode Auto Regressive Integrative Moving Average (ARIMA) dan meramalkan jumlah penduduk pada tahun 2021– 2023 dengan metode ARIMA. Proses peramalan dimulai dengan identifikasi model data dengan melakukan uji stasioneritas dalam varians dan rata-rata. Dalam mengembangkan model ARIMA, perlu dilakukan analisis fungsi autokorelasi (ACF) dan fungsi autokorelasi parsial (PACF) dengan melihat plot ACF atau PACF. Kemudian melakukan estimasi parameter untuk model ARIMA yang dipilih apakah parameter tersebut significant dan layak untuk dijadikan model. Dilakukan pemeriksaan diagnostik dengan pengujian asumsi normalitas dan asumsi residual white noise. Kemudian, tahap peramalan dan pengecekan tingkat akurasi peramalan dengan nilai MAPE. Hasil penelitian menunjukkan bahwa jumlah penduduk diperkirakan akan meningkat setiap tahunnya. Setelah dianalisis, model terbaik yang didapatkan adalah model ARIMA(0,2,1) karena nilai Mean Absolute Precentage Error (MAPE) dari model tersebut yaitu sebesar 3,62%. Artinya tingkat akurasi dari metode ARIMA tersebut adalah 96,38%.

Abstract

Assessment has an important role in the learning process. Assessment is not only used to see the results of students' learning achievements but is also used to improve the learning process. PISA (Program for International Assessment) is a study of international level assessment organized by the OECD (Organization for Economic Cooperation and Development). Indonesia is one of the participating countries in the PISA study. However, the content of the questions within the PISA framework is still relatively small in the available teaching materials. So educators in Indonesia have begun to make adjustments and conduct research on the development of PISA-type assessments. The purpose of this article is to examine the PISA type of mathematical assessment that has been developed. Then, the potential effects of the problems that have been developed will be seen. This study uses the literature review method by reviewing and reviewing articles on PISA-type mathematical assessments. Article collection was carried out on Google Scholar and Research Gate in the period 2015-2021. Based on the results of the research that has been reviewed, it is known that the potential effects of the developed PISA type of mathematical assessment include problem-solving, mathematical literacy, communication skills, and reasoning abilities.
