Penelitian tindakan kelas merupakan salah satu bentuk penelitian yang berkembang dari action research yang awalnya banyak dilaksanakan di Amerika dan Eropa pada akhir Tahun 1990. Di Indonesia sendiri, penelitian tindakan kelas baru dikenal pada akhir dekade 80-an. Tujuan dari PTK adalah upaya perbaikan pembelajaran di kelas, serta pengembangan keterampilan profesional guru dalam pengelolaan proses pembelajaran. Guru maupun praktisi pendidikan sering menggunakan PTK dalam konteks pemecahan permasalahan pendidikan. Buku Penelitian Tindakan Kelas berisi tentang hal-hal mendasar dan panduan dalam melaksanakan PTK, baik bagi guru, praktisi, maupun seseorang yang sedang mempelajari PTK. Pokok bahasan dalam buku ini mencakup hal mendasar hingga refleksi dari hasil PTK, diantaranya: 1) Konsep Dasar Penelitian Tindakan Kelas; 2) Jenis-jenis Penelitian Tindakan Kelas; 3) Metodologi dan Model Penelitian Tindakan Kelas; 4) Desain dan Prosedur Penelitian Tindakan Kelas; 5) Metode Pengumpulan Data; 6) Instrumen Pengumpulan Data; 7) Analisis dan Penyajian Data; 8) Validitas dan Reliabilitas Penelitian Tindakan Kelas; 9) Pemantauan dan Hasil Evaluasi Penelitian Tindakan Kelas; 10) Format Proposal Penelitian Tindakan Kelas; 11) Laporan dan Teknik Penulisan PTK. Melalui buku Penelitian Tindakan Kelas, diharapkan pembaca mampu memahami secara teoritis dan melaksanakan PTK dengan baik dan benar, serta membantu dalam memecahkan permasalahan pendidikan.

The purpose of this study was to analyze the mathematical problem-solving ability and characters of students who were taught using problem-based learning and ordinary learning based on Islamic perspectives. The instrument used in this study was a test of problem-solving ability and a students’ character questionnaire. This research was a quasi-experimental research with pre-test and post-test control group design. The sample of this research was 84 students from Private Islamic School in Medan, North Sumatera, by using a purposive sampling technique. The data in this research was declared homogenous and normal after being tested using the Levene’s Test and Kolmogorov-Smirnov Test. The hypothesis analyzes used was the Two Way-ANOVA test assisted by SPSS 25. The result showed that there was an improvement in mathematical problem-solving ability and students' characters through problem-based learning based on Islamic perspectives. However, there was no interaction between students' gender and problem-solving ability and character improvement based on Islamic perspectives. The gender factor in problem-based learning was not related to students’ cognitive and affective aspects. Each student with any gender had difference characters, especially related to Islamic perspectives. This research-proven that problem-based learning model had an important role in teaching and learning, and it can be used to improve students' mathematical and character problem-solving ability.

We already know that, there are many learning models that are used to improve the ability to understand mathematical concepts. In this study, researchers will use two learning models that have been previously studied. But this study is different from previous studies, this study aims to find a better model in improving the ability to understand students' mathematical concepts through test results by applying the flipped classroom and heuristic vee models. The method used in this study is quasi-experimental (quasi-experimental) and testing using the T and N-Gain test. Based on the results of the data analysis conducted, it can be concluded that increasing the ability to understand mathematical concepts of students who use the flipped classroom learning model is far better than vee heuristics.

Tujuan dari penelitian ini adalah untuk mengetahui tingkat kecemasan mahasiswa pgmi selama masa pandemi dimana yang menajdi latar belakang dari penelitian ini nadalah adanya paparan virus corona jenis SARS-CoV-2 sehingga menimnulkan masalah psikologis pada mahasiswa sehingga menimbulkan kecemasan dan stress.penelitian ini menggunakan metode survei dengan teknik pengumpulan data menggunakan angket yang didistribusikan kepada 150 mahasiswa pgmi. Hasil penelitian didapatkan temuan mahasiswa mengalami tingkat kecemasan di masa pandemi ini dengan persetase 50% merasakan sangat cemas, 30% merasa cemas, 15% merasa tidak cemas, dan 5 % merasakan sangat tidak cemas dengan kondisi pandemi yang terjadi sekarang ini. Munculnya kecemasan yang berlebihan atau axienty disosder lebih pada adanya rasa takut terinveksi atau tertular oleh virus corona ini serta keadaan pendapatan atau penghasilan keluarga yang mengalami penurunan.

Education upbringing is one requirement that must be fulfilled by the state, especially education in the state border which incidentally was very isolated, even many Indonesian border areas that have not received a decent education. The purpose of this study was to analyze elementary school facilities and infrastructure services in SD Negeri 24 Selangai, Sanggau Regency, West Kalimantan and to find out what the driving and inhibiting factors were. The analysis knife used is theory. This study uses a descriptive method with a qualitative approach. Data was collected by way of interviews, observation, and documentation. Data analysis uses the Analysis Model of Miles and Huberman. The results of this study indicate that the quality of service facilities and infrastructure at SD Negeri 24 Selangai in Sagau Province is still very poor. Can be seen from the condition of the school, one classroom is used for two study groups, the teacher's room does not have, the principal's room does not have, local only 3 for 6 study groups. The teacher is only 4 people. The attention and seriousness of the regional government and the government are lacking. SD is bordered by Malaysia.
