Pada masa covid-19 pembelajaran dilaksanakan secara daring (online), sehingga dibutuhkan beberapa alat belajar berbantuan ICT yang mampu menunjang efektivitas pembelajaran dengan baik yaitu Geogebra. Penelitian ini bertujuan untuk menelaah efektivitas pembelajaran berbasis masalah berbantuan Geogebra terhadap kemampuan penalaran matematis. Metode yang digunakan dalam penelitian ini adalah metode kuasi eksperimen. Populasi penelitian ini adalah seluruh siswa SMK Swasta di kota cimahi, sedangkan sampelnya dipilih tiga kelas yang banyaknya 80 dari satu SMK swasta di kota Cimahi. Instrumen yang digunakan dalam penelitian ini adalah seperangkat tes kemampuan penalaran yang berbentuk soal uraian sebanyak 4 soal. Soal tersebut sudah memenuhi soal yang baik berdasarkan validitas, reliabilitas, daya pembeda dan indeks kesukaran. Berdasarkan hasil perhitungan menggunakan SPSS 18 diperoleh hasil bahwa model berbasis masalah dengan bantuan Geogebra dengan model berbasis masalah maupun biasa memiliki nilai sign. sebesar 0,000, karena nilai sign. < 0,05, maka dapat disimpulkan bahwa pembelajaran menggunakan model berbasis masalah berbantuan Geogebra lebih efektif dibandingkan model pembelajaran berbasis masalah maupun model biasa ditinjau dari kemampuan penalaran matematis siswa. Dengan demikian penerapan model berbasis masalah berbantuan Geogebra lebih efektif dibandingkan model berbasis masalah maupun konvensional terhadap kemampuan penalaran matematis. Abstract During the Covid-19 period, learning was carried out online, so it needed several ICT-assisted learning tools that were able to support the effectiveness of learning well, namely Geogebra. This study aims to examine the effectiveness of Geogebra-aided problem-based learning on abilities. The method used in this study is a quasi-experimental method. The population of this study was all private vocational students in the city of Cimahi, while the sample was selected in three classes with a total of 80 from one private vocational school in the city of Cimahi. The instrument used in this study was a set of reasoning ability tests in the form of 4-item description questions. These questions have fulfilled good questions based on validity, reliability, distinguishing features and difficulty index. Based on the results of calculations using SPSS 18 shows that the problem-based model base on Geogebra with problem-based and ordinary models has a sign value. of 0.000, because of the sign value. <0.05, it can be concluded that learning using a Geogebra-assisted problem-based model is more effective than problem-based learning models and ordinary models in terms of students' mathematical reasoning abilities. Therefore the results are obtained the application of a Geogebra-based problem-based model is more effective than a problem-based or conventional model in terms of mathematical reasoning abilities.
The purpose of this study is to examine the influence of asset structure, free cash flow (FCF)

Abstract The objective of this research is to find out the use of Whatsapp Messenger as a mobile media to learn writing in EFL classes.Several researchers have attempted to prove applicability of mobile learning as modern ways of teaching and learning (Naismith, 2004:115). Moreover, applying portable technologies have been demanded by most of the modern learners who oftentimes are forced to study anywhere, and anytime, for example, at work, in the bus or at weekends (Evans, 2008:115).The research was motivated by the students’ difficulties in writing. The sample of this research was three classes of first grade students of English Department of Unswagati. The instrument of this research was questionnaire sheet. Data from questionnaire sheet was analyzed based on the frequency students’ answers and then was calculated and interpreted into percentages. The result shows WhatsApp Messenger attracts the students interest and also the students have positive responses towards the using ofWhatsAppMessenger. In applying WhatsApp group, the writer concluded that, learning using WhatsApp group has effective to develop their creativity in writing skill. On the other hand, the result from the questionnaire sheet indicated that almost of students is active in learning to writing recount text. Students can learn out of the classroom. Beside WhatsApp can be used privately, it can be used for students’ education. The students can use their gadget positively for their ability in learning English. The students can improve their knowledge in learning ICTs (Information and Communication Technologies).

<p><strong>ABSTRACT</strong>: This research was conducted to test college students’ academic buoyancy, especially working college students and not working college students in Jakarta. Academic bouyancy is the ability of students (in this research is college students) to successfully overcome obstacles and problems that occur in everyday academic life, such as facing tasks and examinations from various subjects intended to measure their abilities (Martin & Marsh in Tarbetsky, Martin & Collie, 2017). Using independent sample of comparative study with quantitative method to understand the differences of academic buoyancy in working college students and not working college students in Jakarta. Data is gathered by using academic buoyancy questionnaire made by researcher based on Martin & Marsh (2010) aspect of academic buoyancy. Academic buoyancy questionnaire validity score range from 0.291 to 0.676 and the reliability score is 0.920. Questionnaire is given to 388 college students in Jakarta. Result shows that there are differences between working college students’ and not working college students’ academic buoyancy in Jakarta. The differences of academic buoyancy is explained by the differences on its aspect, self-efficacy, planning, persistence, and anxiety. Working college students’ and not working college students’ academic buoyancy are both high in categorization, but working college students’ mean are higher than not working college students’ mean. For college students who work can reduce anxiety by setting aside a few minutes every day to calm down and make a priority scale to solve important and urgent things first. For college students who are not working, they are expected to make a learning plan in detail and make a target value that is in accordance with their own abilities.</p><p><strong>Keywords</strong>: academic buoyancy, college student, working, not working</p><p><br /><strong>ABSTRAK</strong>: Penelitian ini dilakukan untuk menguji academic bouyancy pada mahasiswa khususnya mahasiswa yang bekerja dan tidak bekerja di Jakarta. Academic bouyancy adalah kemampuan siswa (dalam penelitian ini adalah mahasiswa) untuk berhasil mengatasi hambatan dan masalah yang terjadi dalam kehidupan akademik sehari-hari, seperti menghadapi tugas-tugas dan ujian dari berbagai mata pelajaran yang dimaksudkan untuk mengukur kemampuan yang dimiliki (Martin & Marsh dalam Tarbetsky, Martin & Collie, 2017). Jenis penelitian yang digunakan adalah penelitian komparatif sampel independen dengan metode kuantitatif untuk mengetahui perbedaan academic buoyancy yang dimiliki oleh mahasiswa bekerja dan tidak bekerja di Jakarta. Pengumpulan data dilakukan dengan menggunakan kuesioner academic buoyancy yang disusun oleh peneliti berdasarkan aspek yang dikemukakan oleh Martin & Marsh (2010). Dari hasil uji coba terhadap kuesioner yang disusun peneliti didapatkan rentang validitas sebesar 0.291-0.676 dan nilai reliabilitas sebesar 0.920. Kuesioner penelitian dibagikan kepada 388 mahasiswa di Jakarta secara secara langsung dan daring. Hasil penelitian menunjukkan bahwa terdapat perbedaan academic buoyancy pada mahasiswa bekerja dan tidak bekerja di Jakarta. Perbedaan juga terlihat pada aspek self-efficacy, planning, persistence, dan anxiety. Academic buoyancy pada mahasiswa bekerja dan tidak bekerja berada pada kategori yang tinggi dengan nilai rata-rata mahasiswa bekerja lebih tinggi daripada nilai rata-rata mahasiswa tidak bekerja. Untuk mahasiswa yang bekerja dapat mengurangi kecemasan yang dirasakan dengan menyisihkan beberapa menit setiap hari untuk menenangkan diri dan membuat skala prioritas untuk menyelesaikan hal yang penting dan mendesak terleboh dahulu. Bagi mahasiswa yang tidak bekerja, diharapkan untuk membuat rencana belajar dengan detil dan membuat target nilai yang sesuai dengan kemampuan diri sendiri.</p><p><strong>Kata kunci</strong>: academic buoyancy, mahasiswa, bekerja, tidak bekerja</p>
<p><em>Badminton is one of popular sports and has resulted many achievements in Indonesia. The effort of Indonesian Badminton Union (Persatuan Bulutangkis Seluruh Indonesia) to regenerate young talented players is the shuttletime program in which they collaborate with schools to teach badminton. Competition anxiety has become a psychological factor that hinders players’ performance. Amateur athletes are more easily feel anxious compare with professionals’ athletes because of the lack of experiences in competition and emotion management. Anxiety reduction training sometimes is not a priority as happened at UNJ badminton club. The aime of this research is to identify the effectivity of anxiety management training towards competition anxiety among UNJ adolescents’ athletes. Anxiety training that gave to them was relaxation technique and self talk. This research was experimental research which is one group design. The treatment was anxiety training, the anxiety tes was given before and after training. The results revealed t score= 0.201 with sig 0.842 > 0.05, mean the anxiety treatment still could not decreased anxiety. The intensity for practicing anxiety management whereas there were participants did not do the technique that had been taught and the lack encouragement from the coach to the team before competition were some of variables that made the training was not effective for the badminton athletes.</em><em></em></p><p><em> </em></p><p><strong><em>Key</em></strong><strong><em>w</em></strong><strong><em>ords</em></strong><em>: </em><em>a</em><em>nxiety </em><em>m</em><em>anagement</em><em>;</em><em> </em><em>c</em><em>ompetition </em><em>a</em><em>nxiety</em><em>;</em><em> </em><em>b</em><em>adminton </em><em>a</em><em>thletes</em><em>;</em><em> </em><em>a</em><em>dolescent.</em></p>
