Efektivitas Pembelajaran Daring Berbasis Masalah Berbantuan Geogebra Terhadap Kemampuan Penalaran Matematis Di Era Covid-19

Abstract

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.

Commemorating One-Year of the COVID-19 Pandemic: Indonesian and International Issues of Secondary and Tertiary Mathematics Learning

“…Need to develop further mathematical logic learning that is more innovatively integrated with ICT. (Sugandi & Bernard, 2020) The implementation of Geogebra-assisted problem-based model was more effective than both problem-based and conventional models of mathematical reasoning abilities.…”

“…Different aspects of the students' perspective were covered. In terms of the cognitive aspect, several studies focused on viewing students' mathematics competencies, namely problem-solving (Kusmaharti & Yustitia, 2020), mathematical communication (Sari et al, 2020), conceptual understanding (Anugrahana, 2021), and mathematical reasoning (Sugandi & Bernard, 2020). Other studies revealed common purposes related to mathematics learning outcomes (Sari et al, 2020) and learning di culties (Anugrahana, 2021) during the pandemic.…”

The Effectiveness of PBL Models Based on Google Meet on the Ability of Mathematical Problem Solving

“…In the current conditions is required a variety of learning models are more varied in elementary school (Herliandry et al, 2020;Meilasari et al, 2020). One of them is the model of PBL-based google meet because it is more effective than using conventional learning models on students in primary schools in particular topics chosen and essential in applied mathematics on the learning online (Sugandi & Bernard, 2020). Learning mathematics with the use of PBL models based on google meet is one of the models that can be used in elementary school to plan for the learning of mathematics fun and meaningful for learners, as well as evoke the initiative or the role of students in exploring the knowledge, thus affecting the improvement of the problem-solving ability of learners (Santika et al, 2020;Sugandi & Bernard, 2020).…”

Meaningful learning will give the opportunity to students to gain experience and develop social emotions that can later be used in their day-to-day (Bressington et al, 2018;Kostiainen et al, 2018).…”

Inovasi Video Pembelajaran Berbantuan Aplikasi Powtoon pada Materi Keliling dan Luas Bangun Datar

“…Diberlakukannya sistem pembelajaran daring atau dalam jaringan ini tentunya menimbulkan dampak yang besar terhadap proses belajar mengajar yang berlangsung. Guru dan siswa tidak lagi dapat berinteraksi secara langsung di sekolah, melainkan hanya dapat berkomunikasi menggunakan bantuan teknologi informasi, seperti Whatsapp, Zoom, Google Meet, Google Classroom dan lain sebagainya yang tentunya memerlukan perangkat pendukung berupa handphone atau laptop dan akses jaringan internet yang memadai (Chang et al, 2020;Hulukati et al, 2021;Putria et al, 2020;Sugandi et al, 2020). Sisi positif yang didapat dari penerapan pembelajaran daring ini adalah tidak adanya batasan ruang maupun waktu dalam belajar, serta dapat menghemat waktu dan biaya transportasi (Anugrahana, 2020;Fauzy & Nurfauziah, 2021;Hwang et al, 2020).…”
