The COVID-19 pandemic has changed the online learning process from offline to online. One of the references for measuring digital literacy levels is to directly observe the learning process that occurs using platforms that support distance learning. The purpose of this study was to analyze the digital literacy skills of elementary school students in the use of distance learning media and analyze the understanding of digital media of elementary school students in the use of distance learning media. The method used is qualitative with a phenomenological design. Data collection techniques using interview techniques, field observations, and documentation. The data validity technique uses source and technique triangulation. At the same time, the data analysis technique uses an inductive step. The results showed that the students of SD N 1 Brajan had a good level of digital literacy; students knew the benefits of digital media used as learning media, such as understanding the help of the media features used for practical benefits. Meanwhile, in applying digital media, students can also use it as a learning medium. This is because students are used to using these media in everyday life. In contrast, some students have difficulty applying digital media because they have the reason that the cellphones they use are still alternating with their parents, so the infrequent use of digital media will affect students' digital literacy skills. Teachers can make efforts to improve students' digital skills by providing learning media that can provide additional learning in the use of learning media that are foreign to students.

Buku teks yang memiliki konten isi memiliki peranan yang sangat penting dalam menunjang proses pengetahuan siswa secara utuh. Fakta menunjukkan bahwa sebagian besar guru bergantung pada buku teks, hingga ada keluhan pada isi dan sajian buku teks. Penelitian ini bertujuan untuk mendeskripsikan karakteristik sajian buku teks kelas tujuh pada materi perbandingan berbalik nilai ditinjau dari teori prakseologi yang memiliki empat elemen analisis, yaitu tugas, teknik, teknologi, teori. Penelitian ini adalah penelitian deskriptif kualitatif dengan objek penelitian adalah buku teks siswa kelas VII terbitan Kemendikbud, serta subjek penelitian melibatkan guru kelas tujuh. Temuan penelitian menunjukkan bahwa sajian buku teks materi perbandingan berbalik nilai sudah cukup baik. Namun, ada beberapa sajian yang perlu dilengkapi. Materi perbandingan berbalik nilai sudah bersifat kontekstual, tetapi terdapat ilustrasi tidak sesuai perkembangan kognitif siswa. Sajian teknik kurang lengkap dan tidak memberikan ruang bagi siswa untuk memilih cara menyelesaikan kasus perbandingan berbalik nilai, tidak ada kesempatan bagi siswa untuk memberikan justifikasi terhadap teknik yang dilakukan, serta beberapa tidak ada situasi untuk membuat siswa menyimpulkan terhadap hasil justifikasi yang dilakukan. Textbooks with content are very important in supporting the students’ knowledge process. The facts show that most teachers depend on textbooks, so there are complaints about the content and presentation of textbooks. This study aims to describe the characteristics of a seventh-grade textbook presented on inverse proportion in terms of the praxeological theory, which has four elements of analysis, namely task, technique, technology, and theory. This research is a qualitative descriptive study with the object of research being a textbook of class VII students published by the Ministry of Education and Culture. The research subject involves seventh-grade teachers. The study results show that the presentation of inverse proportion in textbooks is good enough. However, there is some present that needs to be completed. The inverse proportion is already contextual, but some illustrations do not match students' cognitive development. The presentation of techniques is incomplete and does not provide space for students to choose how to solve cases of inverse proportion, there is no opportunity for students to justify the techniques used, and in some situations, there are no situations to make students conclude on the results of the justifications carried out.

The equal sign seems to be interpreted differently by students depending on the learning experiences they have had in the early grades. In fact, the interpretation of the equal sign as a relational symbol does not seem easy or fast for many students to understand. This study aims to explore how students from elementary school to college students describe their understanding of the equal sign. The Qualitative Comparative Analysis can be used to analyze several cases in complex situations so that it fits the purpose of this study. The process of collecting data through the method of written assignments, semi-structured interviews, and documentation was carried out in one time period. This study involved 30 participants in Bandung, Indonesia. The results show that although there are substantial differences in viewing the equal sign, there are similarities in terms of dependence on computational methods in drawing conclusions. This is related to how their experience of number sentences in lower grades places more emphasis on rules than on the meaning of concepts.

This paper reports an investigation of students' understanding of the concept of factorization in algebraic forms learned in secondary school. A total of 31 grade 8th junior high school students were selected by purposive sampling technique as respondents in this case study research. The case study approach is considered in accordance with the objectives of this study, namely obtaining in-depth knowledge of student problems, knowing the causes of these problems, and efforts that can be made to help overcome them. Methods of collecting data using written tests, interviews, and documentation. Data analysis techniques include data reduction, data presentation, and drawing conclusions. The results showed that there was a misunderstanding of students' concepts about the concept of factorization in algebraic forms so that they experienced difficulties in "algebraic manipulation". One of the causes of these difficulties is the lack of students' understanding of the equals sign as a sign of equality. The principle of mathematical equivalence serves as the main link between arithmetic and algebra. The operation transformation and the meaning of the equals sign in arithmetic as equality can underlie "algebraic manipulation".

Konsep peluang merupakan konsep dasar yang perlu dipahami oleh siswa karena pemahaman konsep tersebut akan terus digunakan pada jenjang selanjutnya. Namun, masih banyak siswa yang mengalami hambatan dalam mempelajari topik tersebut. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis hambatan belajar (learning obstacle) siswa pada materi konsep peluang. Metode yang digunakan adalah metode penelitian kualitatif dengan pendekatan fenomenologi yang melibatkan 22 siswa SMP kelas IX dan 24 siswa SMA kelas X di dua sekolah di Kabupaten Wonosobo, Jawa Tengah, Indonesia. Pengumpulan data menggunakan triangulasi dengan pemberian tes diagnostik, wawancara guru dan siswa, serta analisis buku ajar yang digunakan (analisis dokumen). Hasil penelitian menunjukkan bahwa siswa mengalami hambatan belajar dimana kurangnya ketertarikan siswa terhadap materi konsep peluang, ketidaksiapan siswa berkaitan dengan hal teknis yang bersifat kunci dari proses pembelajaran seperti ruang sampel dan titik sampel, dan siswa masih kesulitan dalam menguasai konsep prasyarat himpunan, yaitu kesulitan memahami dalam mendaftarkan anggota suatu himpunan (ontogenic obstacle). Hambatan lain yang dialami siswa yaitu, banyaknya miskonsepsi siswa pada penyelesaian permasalahan terkait konsep peluang (epistemological obstacle) serta alur pembelajaran yang belum sesuai dengan kebutuhan dan karakteristik siswa (didactical obstacle). Hambatan-hambatan tersebut harus dipertimbangkan dalam pengembangan desain didaktik yang lebih optimal untuk mencapai tujuan pembelajaran yang diharapkan. The concept of probability is a basic concept that students need to understand because this concept will continue to be used at the next level. However, many students still have obstacles in learning this topic. This study aims to identify and analyze student learning obstacles in the concept of probability. The method used is qualitative research method with phenomenological approach involving twenty two 9th grade students and twenty four 10th grade students in two school in Wonosobo Regency, Central Java, Indonesia. Data collection uses triangulation by giving diagnostic tests, teacher and student interviews, and analysis of the textbooks used (document analysis). The results showed that students have learning obstacle which there was a lack of student interest in the concept of probability, students' unpreparedness related to key technical matters of the learning process such as sample space and sample points, and students still have difficulty mastering the concept of sets, they have difficulty writing members of a sets (ontogenic obstacle). Another obstacle is the number of misconceptions in solving problems of probability (epistemological obstacle) and the learning trajectory that is not in accordance with the needs and characteristics of students (didactical obstacle). These learning obstacles must be considered in the development of a more optimal didactical design to achieve the expected learning objectives.
