The subjects in this study were 34 students of Mathematics Education at the University of Balikpapan who were studying the Theory of Numbers. Data collection techniques are carried out by observation (observation of chat activities within the WA Group), documentation, and learning outcomes tests. However, the results showed that the implementation of online learning through the WA Group went well. This can be seen from the achievement of student learning outcomes which shows that 27 out of 34 students get scores above 70. In addition, students also feel that they have new learning experiences, can express themselves in discussions, the atmosphere of learning is very relaxed, learning becomes more update, and can be accessed anywhere if students forget the material they have learned.","PeriodicalId":331197,"journal":{"name":"De Fermat : Jurnal Pendidikan Matematika","volume":"15 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130474667","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}

Yang menghasilkan kelas X IPS 1 di SMA Negeri 1 Cisaat menjadi subjek penelitian dengan sampel berjumlah 30 siswa dari populasi 120 siswa yang terbagi empat kelas (X IPS1, X IPS 2, X IPS 3, dan X IPS 4). Instrumen yang digunakan adalah instrumen tes hasil belajar matematika dan instrumen angket kecemasan matematis. Uji instrumen berupa validas isi, validitas, reliabilitas, daya pembeda, dan tingkat kesukaran. Metode pengumpulan data dilakukan melalui tes dan angket. Teknik analisis data yang dilakukan adalah analisis skala likert untuk uji hipotesis menggunakan uji korelasi Rank Spearman dengan taraf signifikan 1%. Hasil penelitian disimpulkan bahwa ada pengaruh negatif antara kecemasan matematis dengan hasil belajar matematika kelas X IPS 1 di SMA Negeri 1 Cisaat. Pengaruh negatif dalam penelitian ini yaitu jika kecemasan tinggi maka hasil belajar rendah atau jika kecemasan rendah hasil belajar tinggi.

This research was conducted in 4 (four) State High Schools in Semarang City, and 498 XII graders has been chosen randomly. The result is that 55% of students are pessimistic, and 45% are optimistic. The research hypothesis that there are differences in mathematics learning achievement between optimistic and pessimistic students has been proven in the results of this study. Significant differences were also confirmed through the results of statistical calculations, and can be indicated by the average score of the optimistic students is higher than pessimistic students.
