Abstract: This study aims to analyze the difficulties of students in developing student worksheets (LKS) and interactive mathematics learning media. This research is descriptive qualitative research with a case study approach. The subjects of this study were students of the Mathematics Education Study Program at Widya Dharma University, Klaten. The data collection method used in this research is documentation, observation, and interviews. Method triangulation techniques are used to obtain valid data by comparing the results of observations with the results of interviews. The data analysis process in this study was carried out based on the model of Miles, which includes data condensation, data presentation, and drawing conclusions. The results of this study show that students experience difficulties in developing worksheets and interactive learning media. The types of difficulties are (1) difficulty in arranging findings or formula construction on certain materials, (2) difficulty in compiling worksheets and learning media that require students to provide varied responses, (3) difficulties in developing contextual and challenging initial problems and (4) difficulty in constructing apperception.

Abstract

Learning about the normal distribution is closely related to function formulas and theories dealing with mathematical symbols. This understanding of mathematical normal distribution theories often creates its own obstacles for students. To provide an easier understanding, a visualization is needed in learning, so that students have a clearer picture of the normal distribution. Through the simulation method visualization of the normal distribution theories is carried out. The simulation was carried out using the help of software R. Through the simulation, students can find out the curve of the normal distribution density function and can modify the desired parameters. This can clarify some of the properties of the normal distribution density function. Simulations were also carried out on the cumulative distribution function to provide a clearer picture of the nature of the cumulative distribution function. The transformation of a normally distributed random variable with parameter µ and variance σ2 into a standard normally distributed random variable can also be explained visually. Through this visualization, students have a clearer picture to support theoretical learning mathematically. Furthermore, students have a better understanding in learning material about the normal distribution

Abstract

Project Based Learning learning model, a learning model in the form of a project to be carried out individually or in groups and carried out within a certain period of time. The application of the PjBL learning model assisted by the GeoGebra application aims to improve students' numeracy literacy skills and students' activeness, so that students are expected to have curiosity and be able to understand quadratic function material well. This study used the class action research method (PTK) by taking research subjects class X G students of SMA N 1 Jatinom consisting of 36 students. Based on this research, it was shown that students' numeracy literacy skills experienced an increase seen from the classical average in cycle I of 51.88% increasing to 73.97% in cycle II. Meanwhile, the activeness of students began to increase as seen from the average percentage of students' activeness of 57.29% in cycle I and 72.06% in cycle II. It was concluded that in this study the application of the GeoGebra-assisted PjBL learning model in mathematics learning was able to improve the numeracy literacy skills and the activeness of class X G students of SMA N 1 Jatinom in the 2022/2023 academic year.

Abstract

Internet self-efficacy (ISE) was initiated by Albert Bandura, self-efficacy (SE) is a widely accepted concept that refers to an individual's belief in his ability to complete certain behaviors or tasks in certain situations. The purpose of this study was to determine the relationship between ISE and the learning achievement of 12th-grade high school students. The sample of this study was 12th-grade MIPA 7 SMA Unggulan CT ARSA Foundation Sukoharjo as many as 21 students. ISE data is data obtained from questionnaires distributed to students who have been tested for validity and reliability. On the other hand, learning achievement tests were conducted on students with three-dimensional material. The analysis conducted to determine the relationship between the two variables is bivariate analysis. The results showed that between the ISE variable and Student Learning Achievement, a correlation coefficient value of 0.670 was obtained with a significant relationship between the ISE variable and Student Achievement. The degree of bond correlation value shows a strong/sturdy correlation.

Abstract

Errors in associating some knowledge result in students' mistakes in choosing strategies so that problems cannot be solved. In fact, the new curriculum in Indonesia requires students to be able to solve problems that require higher-order thinking skills. This study aims to describe how students process problems in solving bridge context problems. This research is qualitative research with case study method. This research was conducted in April 2022 with the research subject being a junior high school student in Yogyakarta, Indonesia. The instrument in this research is the problem of high order thinking (HOT) to measure problem solving ability. The instrument was designed based on the mathematics material that students had learned and compiled through five times Focus Group Discussion (FGD) by 3 mathematics lecturers. Data were collected using documentation and interviews then will be analyzed descriptively. Based on the results and discussion presented in the previous section, the authors collect three types of errors in solving problems made by students. The three types of errors are operational, conceptual, and principal errors.

Abstract

Penelitian ini mempunyai tujuan untuk mendapatkan deskripsi profil kemampuan berpikir analitis mahasiswa ketika menyelesaikan soal teori bilangan. Penelitian yang berjenis studi kasus ini mendalami kemampuan berpikir analitis mahasiswa ketika menyelesaikan soal teori bilangan. Penelitian ini mengambil subjek mahasiswa semester 3 yang telah mengikuti perkuliahan teori bilangan pada Program Studi Pendidikan Matematika. Lokasi penelitian adalah Universitas Widya Dharma yang berada di Kabupaten Klaten. Metode tes dan wawancara merupakan metode pengampilan data penelitian ini. Penelitian ini menggunakan peneliti sebagai instrumen utama, tes kemampuan berpikir analitis sebagai dan pedoman wawancara sebagai instrumen bantu. Data profil kemampuan berpikir analisis mahasiswa ketika menyelesaikan soal teori bilangan supaya valid dalam penelitian diperoleh melalui teknik triangulasi. Tiga tahap analisis data penelitian ini adalah kondensasi data, dilanjutkan dengan menyajian data, dan yang terakhir menentukan kesimpulan untuk profil kemampuan berpikir analitis mahasiswa ketika menyelesaikan soal teori bilangan (Miles et al., 2014). Penelitian ini mempunyai tiga hasil berikut: (1) dalam mengerjakan soal kekonruenan modulo mahasiswa menulis ulang soal, tidak menuliskan materi yang relevan, tidak menuliskan strategi, dan kurang teliti; (2) dalam megerjakan soal keterbagian, mahasiswa menulis ulang soal, tidak menuliskan materi yang relevan, tidak menuliskan strategi, dan pembuktian salah; (3) dalam mengerjakan soal induksi matematika, mahasiswa menulis ulang soal, tidak menuliskan materi yang relevan, tidak menuliskan strategi, serta kurang teliti dan tidak menulis kesimpulan.
