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.

Penelitian Tindakan Kelas (PTK) ini bertujuan untuk meningkatkan minat dan prestasi belajar matematika siswa dengan menerapkan Problem-based learning (PBL). Penelitian tindakan ini dilaksanakan dengan empat tahapan (perencanaan, pelaksanaan, pengamatan, dan refleksi), mengadaptasi model Kemmis dan Mc Taggart. Sebanyak 26 siswa kelas VII.B SMP Taman Dewasa Jetis Yogyakarta dijadikan sebagai subyek penelitian ini. Instrumen yang digunakan dalam pengumpulan data terdiri dari angket, lembar observasi, dan tes. Data minat dan keterlaksanaan pembelajaran dianalisis secara kualitatif, sedangkan data prestasi belajar dianalisis secara kuantitatif. Hasil analisis menunjukkan adanya peningkatan minat, serta prestasi belajar matematika yang tinggi dari kondisi awal siswa. Beberapa kesimpulan yang diperoleh antara lain sebagai berikut. Pertama, PBL telah meningkatkan minat belajar dan prestasi belajar siswa di kelas VII.B SMP Taman Dewasa Jetis, Yogyakarta, setelah dilakukan tindakan sebanyak dua siklus. Kedua, peningkatan minat belajar siswa disebabkan karena kedudukan siswa dalam PBL tidak lagi bersifat pasif. Ketiga, hadirnya berbagai masalah-masalah matematika yang dekat dengan konteks kehidupan sehari-hari siswa, membuat konsep matematika yang abstrak lebih mudah dipahami sehingga tidak hanya minat, tetapi prestasi belajar siswa juga mengalami peningkatan. Keempat, keberhasilan pelaksanaan PBL sangat ditentukan oleh konsistensi guru dalam melaksanakan perannya sebagai fasilitator pembelajaran. Sejumlah faktor yang mempengaruhi keberhasilan penelitian juga dibahas dalam artikel. Problem-based learning in mathematics learning: Teacher's efforts to increase students’ learning interest and achievementAbstractThis classroom action research aims to increase learning interest and mathematics learning achievement of students by implementing the Problem-Based Learning (PBL). This action research conduct in four stages (planning, implementation, observation, and reflection) as the Kemmis dan Mc Taggart model suggests. A total of 26 students in class VII.B in SMP Taman Dewasa Jetis, Yogyakarta, were involved in this action research. The instruments used in data collection consisted of a questionnaire, observation sheet, and test. Data on learning interest and implementation of learning are analyzed qualitatively, while data on learning achievement are analyzed quantitatively. The results of the analysis showed an increase in interest, as well as high mathematics learning achievement from the initial conditions. Some conclusions obtained as follows. First, PBL has increased the learning interest and achievement of students in class VII.B of Taman Dewasa Jetis, Yogyakarta, after taking two cycles of action. Second, the increase in students’ interest in learning is due to the position of students in the PBL that is no longer passive. Third, the presence of various mathematical problems that are close to the context of the daily life of students makes the abstract mathematical concepts more easily understood so that not only interest but student achievement also increases. Fourth, the success of implementing PBL is largely determined by the consistency of the teacher in carrying out his role as a facilitator of learning. Several factors that influenced the success of this research were discussed in the article.

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.

As mathematics has been viewed for decades as a strereotyped male domain, gender differences in mathematics learning have received strong attention from scholars. This study, therefore, investigates the influences of gender differences on students’ performance in learning math in secondary school context. The study used a synthesis research. This method of research is undertaken by synthesizing any relevant studies in order to draw conclusion. Some empirical studies investigating the issues of gender difference and learning match were carefully analyzed and synthesized to draw the links between gender differences and secondary students’ academic achievements in learning math. The findings show that male students outperform female students in mathematics learning for three reasons. First, social gender stereotypes about students’ math ability may lead students to endorse math-gender stereotype themselves. This kind of stereotype makes male students more confident whereas female students become more anxious. Second, personality and spatial ability, as representors in mentality, have commonly been proven that another reason for the advantage of male students in mathematics education. The last is physical advantages in which current evidences suggest that males are more active in some brain areas which are related to mathematics ability. This essay highly recommends future research focus on physical reasons of gender difference in mathematics learning.
