<p>The Covid-19 pandemic that occurred forced the learning process to be carried out online or online learning. This study aims to analyze the opportunities and challenges of teachers and students who carry out the online learning process during the Covid-19 pandemic. This research uses a qualitative approach with a case study type. The subjects of this research were class teachers and grade IV elementary school students. The sampling technique used was purposive random sampling. Data collection techniques used interviews and documentation. The data obtained in this study were qualitative data which were analyzed using data triangulation techniques. The results showed that teachers and students got several opportunities and challenges implementing the online learning process during the Covid-19 pandemic. The opportunities for elementary school teachers and students are (1) Technology ability, (2) more accessible learning, (3) expanding learning references. Meanwhile, the challenges faced by elementary school teachers and students in online learning during the Covid-19 pandemic were (1) difficulty achieving learning objectives, (2) network disruption, (3) high cost.</p>

<p><strong>Abstract:</strong> This study aims to develop a picture story book based on Augmented Reality (AR) application. The sample in this study were experts who assessed the validity and practicality of the media. This study use a Research and Development approach with the Borg &amp; Gall model. This study used to purposive random sampling technique. The data in this study were collected with questionnaire techniques. The data analysis technique used to descriptive statistics. The results showed that the learning media in the form of Augmented Reality-based picture story books were declared valid and practical to used in mathematics learning. So, this learning media can be used to accommodate Z generation students in mathematics learning.</p><strong>Abstrak:</strong><em> </em>Penelitian ini bertujuan untuk mengembangkan buku cerita bergambar dengan bantuan aplikasi <em>Augmented Reality</em>. Sampel pada penelitian ini yaitu ahli penilai kelayakan dan kepraktisan media. Penelitian ini menggunakan pendekatan Research and Development dengan model Borg &amp; Gall. Penelitian ini menggunakan teknik sampling purpossive random sampling. Data pada penelitian ini dikumpulkan dengan teknik angket. Teknik analisis data yang digunakan adalah statistik deskriptif. Hasil penelitian menunjukkan bahwa media pembelajaran berupa buku cerita bergambar berbasis <em>Augmented Reality</em> dinyatakan layak dan praktis untuk digunakan pada pembelajaran matematika. Dengan demikian, media pembelajaran ini dapat digunakan untuk mengakomodasi siswa generasi Z pada pembelajaran matematika.

This research is intended to determine the effectiveness of Augmented Reality (AR)-assisted pictorial storybook in improving discipline character of primary school students. The population of this research was all state-run primary schools in in Sleman Regency, Special Region of Yogyakarta, Indonesia. Specifically, the samples were fourth-grade students from two primary schools, where each of them was selected to be control and experiment groups. The method used is an experimental research, while the sampling technique was cluster random sampling technique. The data collection technique was disciplinary character observation technique. Furthermore, the data were analyzed using t-test technique. The results of this research indicated that the value of sig. t-test was 0.00 (<0.05). Thus, it can be concluded that AR-assisted picture storybook was considered effective in enhancing disciplinary character of primary school students. Therefore, it is recommended that the use of AR can be improved and disseminated to reach the learning objectives of primary school students, specifically in enhancing discipline character.

Penelitian ini bertujuan untuk mengetahui peningkatan hasil belajar siswa sekolah dasar dengan model Cooperative learning tipe Numered heads together pada pembelajaran matematika. Berdasarkan pembelajaran yang dilakukan di SD Negeri Kadukancas, bahwa hasil belajar Matematika di kelas V masih rendah, yaitu siswa yang mendapat nilai KKM yaitu 65 atau lebih hanya 35,71% (10 siswa) sisanya 64,29% (18 siswa) di bawah KKM. Hal ini disebabkan karena guru tidak pernah menggunakan pembelajaran secara kelompok. Tujuan penelitian  tindakan kelas ini adalah untuk mengetahui apakah dengan menerapkan model kooperatif tipe Numbered Heads Together dapat meningkatkan hasil dan aktivitas belajar siswa pada mata pelajaran matematika. Prosedur penelitian tindakan kelas ini meliputi dua siklus dan setiap siklus terdiri dari perencanaan, pelaksanaan, observasi, dan refleksi. Penelitian tindakan kelas ini dilaksanakan di SD Negeri Kadukancas semester genap tahun pelajaran 2014/2015 dengan subjek kelas V yang berjumlah 28 siswa, terdiri atas 10 siswa laki-laki dan 18 siswa perempuan. Hasil penelitian menunjukkan bahwa pada siklus I, siswa yang mencapai KKM yaitu memperoleh nilai sama atau lebih dari 65 sebanyak 19 siswa (67,86%), mengalami peningkatan sebesar 32,16% dari data pra siklus. Sedangkan pada siklus II, siswa yang mencapai KKM yaitu memperoleh nilai sama atau lebih dari 65 sebanyak 25 siswa (89,29%), mengalami peningkatan sebesar 21,43% dari data siklus I. Dengan demikian dapat disimpulkan bahwa pembelajaran dengan menggunakan model kooperatif tipe Numbered Heads Together dapat meningkatkan hasil belajarmatematika.

<span>This study aims to analyze the effectivity of interactive multimedia with the theocentric approach on the analytical thinking skills of elementary school students in science learning. This study used a quantitative approach with a quasi-experimental type. The sampling technique used cluster random sampling with 67 students. The data were collected through analytical thinking skills tests given before and after science learning. The data analysis technique used descriptive and inferential statistics analysis by comparing the increase in the average results of the test and t-test. The research results show that the increase of the average value of students' analytical thinking skills in the experimental class is higher, which is an increase of 44.74% compared to the control class which only increases by 17.20%. The results of the t-test also show that there is a significant effect between interactive multimedia with theocentric approach on students' analytical thinking skills with a significance value of 0.00 (&lt;0.05). Therefore, interactive multimedia with the theocentric approach is effectively used to improve the analytical thinking skills of elementary school students in science learning.</span>
