The purpose of this study is to describe the mathematical disposition of students who use blended learning during the Covid-19 pandemic. This research is a descriptive qualitative research. The research subjects were four students from the sixth semester of mathematics education study program. The research instrument was a student mathematical disposition questionnaire. The results of the study concluded that the average level of mathematical disposition of students was classified as moderate. If seen from the indicators, only the monitor and evaluate indicators are classified as high category. Indicators of persistence and perseverance, especially when lecturers present interesting contextual problems. Many indicators of curiosity arise when lecturers invite students to be active in learning, for example students are invited to study in groups. Many self-confidence indicators appear when lecturers ask students questions. While many flexible indicators appear when lecturers give open ended questions.

Penelitian ini bertujuan mengetahui efektivitas dari penggunaan model pembelajaran reciprocal teaching melihat kepada penelitian-penelitian yang menggunakan metode ini dalam meningkatkan kemampuan siswa, meningkatkan pemahaman konsep matematika, mempengaruhi sikap positif siswa, lelbih percaya diri, dan pembelajaran yang lebih aktif. Metode penelitian yang digunakan dalam penelitian ini adalah dengan pendekatan kualitatif. Sedangkan tipe penelitian dalam penelitian ini menggunakan deskripsi evaluatif. Subjek dalam penelitian ini adalah beberapa penelitian yang sudah dilakukan sebelumnya yang membahas penggunaan reciprocal teaching dalam pembelajaran Matematika. Teknik pengumpulan data dalam penelitian ini adalah menggunakan teknik dokumentasi. Penelitian-penelitian yang digunakan dalam penelitian ini adalah penelitian yang dilakukan selama 7 tahun terakhir, dan penelitian-penelitian tersebut menggunakan tema yang sama yaitu penggunaan reciprocal teaching dalam pembelajaran Matematika. Hasilnya adalah metode reciprocal teaching dapat digunakan oleh para pendidik khususnya dalam pembelajaran Matematika untuk meningkatkan kemampuan matematis siswa, meningkatkan keaktifan siswa dalam belajar, memotivasi siswa lebih baik, meningkatnya kemampuan penalaran siswa, dan meingkatkan efektivitas kemampuan komunikasi matematis siswa.

Penelitian ini bertujuan untuk mengidentifikasi kemampuan penalaran aljabar siswa dalam pemecahan masalah pola bilangan. Jenis penelitian ini adalah kualitatif deskriptif, subjek penelitian ini adalah kelas VIII SMP Muhammadiyah 2 Tangerang. Teknik pengumpulan data pada penelitian ini berupa tes, wawancara dan dokumentasi. Berdasarkan hasil tes dikelompokan menjadi tiga kelompok yaitu tinggi, sedang dan rendah. Setiap kelompok diambil masing-masing 1 siswa untuk dijadikan responden. Hasil menunjukkan bahwa kelompok dengan kategori kemampuan tinggi berada pada karakteristik dan tingkat penalaran aljabar yang lebih tinggi dari tingkat 1 namun belum mencapai ke tingkat 2, kategori kemampuan sedang berada pada karakteristik dan tingkat penalaran aljabar tingkat 1 dan dengan kategori kemampuan tinggi berada pada karakteristik dan tingkat penalaran aljabar tingkat 0

This study aims to analyze the ability to solve mathematical problems based on the characteristics of students' thinking style: Concrete Sequential (CS), Abstract Sequential (AS), Concrete Random (CR), and Abstract Random (AR). This research was carried out at one of the junior high schools in Tangerang, Indonesia. The subjects were 20 Year 7 students, with different thinking style. This research employed a qualitative approach. The instruments used are problem-solving tests and non-problem-solving tests on the characteristics of students' thinking style and a test of mathematical problem-solving ability accompanied by interview results. The data were analyzed descriptively to describe the test results of students' mathematical problem-solving abilities. The results showed that CS-type students could understand the problem in accordance with the indicators. Type AS students can understand but do not write the steps in detail. AR students are as well-understood but less thorough about their calculations. Meanwhile, CR students can understand only a few parts of problem-solving.

The purpose of this study is todetermine whether the  variables of  occupational health safety (K3) and work environment affect the performance  of  PT employees.  Arteria Daya Mulia Cirebon. The population in this study was 75 karyclouds. The sampling technique in this study used saturated samples. The sampel collected for this  study was 75 respondents consisting of  permanent employees. This type of research uses quantitative techniques with an associative approach. In this research,  data was obtained from research instruments using questionnaires and processed using IBM SPSS 25 software. A value of 1 indicates strongly disagreeing and a value of 5 indicates strongly agreeing. Based on the multiple regression analysis values obtained results of 216,385 > 3.12, it was concluded that occupational health safety (K3) and the work environment had an influence together (simultaneously) positively and significantly on the performance of net B production employees at PT. Arteria Daya Mulia Cirebon by 85.3%. The remaining 14.7% was influenced by other factors outside the study.
