This research is a qualitative research with descriptive method. The subjects of this study were 5 grade IX students of SMP Negeri 24 Tangerang. The data collection  technique used a questionnaire questionnaire containing questions about student responses to online learning in mathematics. Data analysis in this study used descriptive statistical analysis. The results of the study are shown from the results of the calculation of the percentage of student responses to online learning in mathematics subjects is 60% with the qualification criteria \"less effective\". This happens because students are not motivated to participate in online learning, and when implementing online learning in mathematics there are still many problems faced by students including not all students have cellphones to carry out online learning, limited internet quota, unstable internet network, and students find it difficult to understand the material in mathematics. So, from the various problems faced by students during online learning, this is what makes the implementation of online learning less effective. \u0000 Keywords: Online Learning, Pandemic Period, and Math. \u0000  \u0000Abstrak \u0000Penelitian ini bertujuan untuk mengetahui efektivitas pembelajaran daring selama masa pandemic.

Analisis data dalam penelitian ini menggunakan analisis statistik deskriptif. Hasil Penelitian ditunjukkan dari hasil perhitungan persentase respon siswa terhadap pembelajaran daring pada mata pelajaran matematika adalah 60% dengan kriteria kualifikasi“kurang efektif”. Hal ini terjadi karena siswa tidak termotivasi mengikuti pembelajaran daring, dan pada saat pelaksanaan pembelajaran daring pada mata pelajaran matematika masih banyak permasalahan yang dihadapi siswa diantaranya tidak semua siswa mempunyai handphone untuk melaksanakan pembelajaran daring, kuota internet yang terbatas, jaringan internet yang kurang stabil, dan siswa sulit untuk memahami materi pada mata pelajaran matematika. Maka, dari berbagai permasalahan yang dihadapi siswa selama pembelajaran daring, hal inilah yang menjadi pelaksanaan pembelajaran daring menjadi kurang efektif. \u0000Kata Kunci: Pembelajaran Daring, Masa Pandemic, Mata Pelajaran Matematika.","PeriodicalId":153921,"journal":{"name":"MEGA: Jurnal Pendidikan Matematika","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125303243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dari beberapa data yang telah dianalisis, diperoleh bahwa teknik cognitive behavioral therapy (CBT) bermanfaat positif dalam mengurangi tingkat kecemasan matematis siswa. Akar dari kecemasan pada siswa bermula dari adanya rasa takut akan suatu hal, dalam konteks penelitian ini yaitu matematika. Terdapat berbagai teknik yang digunakan oleh guru untuk memanfaatkan terapi kognitif-tingkah laku dengan jumlah sesi yang berbeda-beda. Dalam penggunaan teknik cognitive behavioral therapy (CBT) orang tua dan guru matematika berperan penting dalam keberhasilan untuk menurunkan kecemasan matematis siswa.
