Peningkatan Kemampuan Siswa dalam Menyelesaikan Masalah Matematika dengan Pembelajaran Daring Asinkronus dan Sinkronus

Online learning during the Covid-19 pandemic experienced various obstacles, especially on quotas, internet signals, and unsatisfactory learning outcomes. This research was aimed to improve the ability of 7th grade junior high school students in solving mathematics problems through asynchronous and synchronous approaches using learning videos, student worksheets and mathematics problems. This research was classified as class action research. The research subjects were 14 of 7th grade students from a public junior high school located on the suburb of Palangka Raya city, Central Kalimantan in the 2021/2022 academic year. The research was carried out in two cycles where the stages of each cycle were planning, implementating, observing and reflecting. The research instruments were lesson plans, mathematics problems, student worksheets, videos, pre- quizzes and end-of-cycle tests. The results of first cycle showed that average of the students’ score was 7,1 (scale of 0-16) which 5 of 14 students (35,7%) sgot score at least 2 (scale of 0-4) in each problem. At second cycle, average of the students’ score was 10.4 and all students got score at least 2 in each problem. Thus, the online learning in this research was able to improve students' ability to solve mathematics problems.Pembelajaran daring selama pandemi Covid-19 mengalami berbagai kendala terutama pada kuota, sinyal internet dan hasil belajar yang kurang memuaskan. Penelitian ini bertujuan untuk meningkatkan kemampuan siswa-siswa SMP kelas 7 dalam menyelesaikan masalah matematika melalui pendekatan asinkronus dan sinkronus menggunakan video pembelajaran, lembar kerja siswa dan masalah matematika. Penelitian ini tergolong penelitian tindakan kelas. Subjek penelitiannya adalah 14 siswa kelas 7 dari salah satu SMP negeri di pinggiran kota Palangka Raya, Kalimantan Tengah tahun ajaran 2021/2022. Penelitian dilaksanakan dalam dua siklus dimana tahap-tahap di setiap siklusnya adalah perencanaan, pelaksanaan, pengamatan dan refleksi. Instrumen penelitiannya adalah rencana pelaksanaan pembelajaran, masalah matematika, lembar kerja siswa, video, kuis prapembelajaran dan tes akhir siklus. Hasil penelitian siklus I menunjukkan bahwa rata-rata skor siswa sebesar sebesar 7,1 (skala 0-16) dimana 5 dari 14 siswa (35,7%) memperoleh skor setidaknya 2 (skala 0-4) di setiap masalah. Pada siklus II, rata-rata skor siswa sebesar 10,4, dan semua siswa memperoleh skor setidaknya 2 di setiap masalah. Jadi, pembelajaran daring dalam penelitian ini mampu meningkatkan kemampuan siswa dalam menyelesaikan masalah matematika
