The purpose of this study is to see the differences in the mean increase in student mathematics learning outcomes in the Auditory, Intellectually, Repetition (AIR) model and reciprocal teaching (RT) model. The sample in this study were 25 students as the experimental class 1 and 23 students as the experimental class 2. This research was an experimental study with a nonequivalent control group design. The data analysis used was descriptive and inferential analysis. The results of the descriptive analysis showed that the mean pretest score of the experimental class 1 was 51.64 and the posttest result was 70.88 with the increase in student mathematics learning outcomes reaching 0.39. While the mean pretest score of experimental class 2 was 36.52 and the posttest result was 70.48 with the increase in student mathematics learning outcomes reaching 0.51. The variance of the increase in mathematics learning outcomes in the experimental class 1 was 0.02, and the experimental class 2 was 0.01. The results obtained indicate that the increase in mathematics learning outcomes through the reciprocal teaching learning model is higher than the increase in student mathematics learning outcomes using the AIR learning model.

Tujuan dari penelitian ini adalah ingin melihat efek dari pemberian pembelajaran tambahan terdahap pemahaman materi Kalkulus. Selain itu juga ingin melihat kemampuan Schoology dalam hal pengelolaan kelas online, baik dalam diskusi, kemampuan berkirim pesan, pemberian materi, tugas dan lain sebagainya. Penelitian ini merupakan penelitian eksperimen dengan model desain post test only control group design. Untuk menguji efek yang dihasilkan dari pembelajaran tambahan menggunakan Schoology, diambil dua kelompok kelas mahasiswa pendidikan matematika Angkatan 2017 Universitas Sembilanbelas November Kolaka yang mempunyai kemampuan relatif sama dan homogen, kemudian masing-masing diuji menggunakan aplikasi Schoology. Data yang diperoleh dari hasil ujian dianalisis menggunakan statistik deskriftip dan inferensial. Mahasiswa yang mendapat pembelajaran tambahan mempunyai pemahaman konsep materi yang lebih baik dibandingkan mahasiwa yang tidak mendapat pembelajaran tambahan. Selisih rataan pemahaman konsep mereka sebesar 31,89. Hasil inferensi statistik membuktikan bahwa perbedaan tersebut sangat signifikan. Oleh karena itu disimpulkan bahwa pemberian tambahan belajar bagi mahasiswa pada materi Kalkulus dapat meningkatkan pemahaman materi bagi mereka. Selain itu, Schoology yang merupakan sosial medianya para pelajar dapat meningkatkan motivasi belajar mahasiswa. Dengan meningkatnya motivasi belajar, proses belajar menjadi lebih efektif sehingga implikasi terhadap pemahaman materi menjadi lebih baik. AbstractThe purpose of this study is to look at the effects of providing additional learning in an understanding of Calculus material. It also wants to see the ability of Schoology in terms of online classroom management, both in discussions, the ability to send messages, giving materials, assignments, and others. This research is an experimental study with a post-test only control group design. To test the effects resulting from additional learning using Schoology, two groups of Class 2017 Mathematics education students at the Nineteen November University Kolaka, who had relatively the same and homogeneous abilities, were taken. Each was tested using the Schoology application. Data obtained from the test results were analyzed using descriptive and inferential statistics. Students who receive additional learning have a better understanding of the concept of material than students who do not receive further knowledge. The difference between their mean understanding of the idea was 31.89. The statistical inference results prove that this difference is very significant. Therefore it is concluded that providing additional learning for students in calculus material can improve their understanding of the material. Besides, Schoology, which is social media for students, can increase student motivation to learn. With an increased motivation to learn, the learning process becomes more effective so that the implications for understanding the material are better.

This devotion is aimed to improve the ability of teachers to process research data using SPSS. Things that the background is the lack of the use and knowledge of teachers in the use of SPSS and research works of teachers is lacking, one possible cause is the inability of teachers in data processing, especially using SPSS. This devotion includes four phases, namely, preparation, determination of the participants, the training and guidance of the use of SPSS, and direct practice of use of each of the steps in the data analysis in SPSS. The methods used include lectures and question and answer, targeted discussion groups, guidance and simulation data analysis, and direct practice with SPSS data analysis, and administration tasks. Outputs produced is yielding clues analysis work program SPSS for teachers and guidance techniques and operation of SPSS in data processing as well as the need to retrieve accurate results and capable operation of SPSS in data processing based on the instructions of work to be able to determine the valid data instrument and obtain accurate results.

This study aimed to describe the challenges of higher education in implementing online learning during the pandemic Covid-19 outbreak. This study was a qualitative research with a phenomenological approach. Data were collected from 408 students and 20 Lectures from 6 public universities and 6 private universities in Java, Sumatera, Kalimantan, Sulawesi, Nusa Tenggara, and Maluku, by filling out online questionaires and in-depth interviews via social media. The process of data analysis was data reduction, identifying themes, mapping interrelationships between themes, and concluding findings The results of data analysis showed that there were two main challenges, both for lecturers and students. First, limited resources, such as electronic devices (laptops/smartphones/others), learning resources, electricity, and internet connections. Second, lack of knowledge/skills on how to use the online learning media, finding and/or providing learning resources, managing online learning, providing online measuring tools, and carrying out online assessments. This condition has the greatest impact on students from low economic families, and who live in areas with limited access to learning facilities, such as electricity, and internet connections. Most of them lose learning opportunities because of these limitations.Â Third, the difficulty of time management during the online learning period.
