Abstract

Evaluation can be used to measure the understanding of students' concepts in geometry material. However, there are still many students who have difficulty in understanding the concept of geometry. This often leads to misconceptions. An effort to identify misconceptions is to conduct a three-tier multiple choice-based evaluation test. Evaluation can take advantage of online question maker technology such as the Wondershare Quiz Creator application. The purpose of this research is to develop a three tier multiple choice based evaluation tool using wondershare quiz creator to identify misconceptions that can be used online. The development research model uses the 4D model. The research subjects were students of class VII-A SMPN 5 Lamongan. The research instruments used were interview sheets, validation sheets, test instruments, and questionnaires. The data analysis technique used qualitative and quantitative analysis. The result of the research is an evaluation tool based on three tier multiple choice using wondershare quiz creator to identify misconceptions as seen from: (1) the appropriateness of the evaluation tool meets the valid and effective criteria which reaches more than 60%. As well as with the statistical tests carried out, the instrument has met the criteria given so that the evaluation tool can be used. (2) Types of misconceptions consist of classification misconceptions, correlational misconceptions, and theoretical misconceptions. Of the three types of misconceptions, students experienced the most misconceptions at level 2, namely answering incorrect choice of reasons.

Abstract

Concept understanding is one of the mathematical skills or skills that are expected to be achieved in learning mathematics, namely by demonstrating an understanding of the mathematical concepts being learned, explaining the relationship between concepts and applying concepts or algorithms in a flexible, accurate, efficient and precise manner in problem solving. Mathematical understanding will be meaningful if mathematics learning is directed at developing the ability of mathematical connections between various ideas, understanding how mathematical ideas are interrelated so that a comprehensive understanding is built, and using mathematics in contexts outside of mathematics.Key words: understanding, understanding mathematical concepts, learning mathematics

Abstract

The purpose of this study is to: to find out how much increase in learning activities occurs after using the group work method with the help of LKPD in the WhatsApp application in online learning. This research is a class action research (PTK). The subjects of this study were students of class IX D SMP Negeri 2 Bintan with 34 students. The object in this study is the mathematics learning activity of students of class IX D SMP Negeri 2 Bintan in the 2020-2021 academic year on quadratic equation material. The data collection technique in this study was carried out by observing the activities carried out by students during the online learning process. The data analysis technique was carried out by calculating the average percentage of student activities. The learning process uses the guided discovery learning model with a scientific approach and discussion method. Early in the learning process, the teacher prepares students to carry out group discussion activities to solve problems in the prepared LKPD. After the students finished discussing in groups, then each group presented the results of the discussion in front of the class. At the end of each lesson, students are asked to do an evaluation that is done individually. The evaluation score obtained by the students was then calculated for the class average and the number of students who reached the KKM score. The results showed that after the use of LKPD through WhatsApp in mathematics learning, there was an increase in student activity from cycle 1 to cycle 3. In cycle 1, the percentage of student activity was 41.17%, in cycle 2 it reached 58.97% and in cycle 3 reached 76.07%. It is suggested for further mathematics learning to use LKPD through WhatsApp on other materials as an alternative source of learning for students so that students' learning activities increase.

Abstract

Tujuan penelitian ini untuk : meningkatkan hasil belajar peserta didik di masa pandemi Covid - 19 pada materi Persamaan Kuadrat di kelas 9E SMP N 17 Balikpapan tahun pelajaran 2020 – 2021, dengan menggunakan media pembelajaran video Youtube. Penelitian ini termasuk jenis penelitian tindakan kelas (PTK). Subjek penelitian ini adalah siswa kelas 9E SMP Negeri 17 Balikpapan dengan jumlah siswa adalah 32 siswa. Objek dalam penelitian ini adalah hasil belajar matematika peserta didik kelas 9E SMPN 17 Balikpapan tahun pelajaran 2020 – 2021 pada materi persamaan kuadrat. Teknik pengumpulan data pada penelitian ini dilakukan dengan teknik observasi dan teknik tes. Teknik analisis data dilakukan dengan menghitung rata-rata kelas dan menghitung banyaknya peserta didik yang mencapai nilai KKM sedangkan untuk aktivitas peserta dilakukan dengan menghitung persentase tiap aspek kemudian ditentukan kualifikasinya. Proses pembelajaran dilakukan secara daring menggunakan google meet di awal pembelajaran untuk mempersiapkan peserta didik melakukan kegiatan diskusi kelompok menyelesaikan permasalahan di LKPD yang telah disiapkan. Setelah peserta didik selesai berdiskusi dalam kelompok kecil melalui grup whatsapp, kemudian mempresentasikan hasil diskusinya secara daring di google meet. Setiap akhir pembelajaran, peserta didik diminta untuk mengerjakan evaluasi yang dikerjakan secara individu melalui google form. Nilai evaluasi yang diperoleh peserta didik kemudian dihitung rata – rata kelasnya dan banyak peserta didik yang mencapai nilai KKM. Hasil penelitian menunjukkan bahwa setelah digunakannya video pembelajaran youtube pada pembelajaran matematika, hasil belajar peserta didik mengalami perubahan dari siklus I, siklus II dan siklus III. Rata-rata hasil belajar peserta didik pada siklus I adalah 92 kemudian pada siklus II adalah 71,30 dan meningkat menjadi 76,25 pada siklus III. Sedangkan banyaknya peserta didik yang mencapai nilai KKM adalah pada siklus I siswa yang mencapai KKM sebanyak 100% atau 32 dari 32 siswa menjadi 62,50% atau 20 dari 32 siswa pada siklus II dan meningkat menjadi 68,75 atau 22 dari 32 siswa pada siklus III. Disarankan untuk pembelajaran matematika selanjutnya dapat menggunakan video pembelajaran melalui youtube pada materi lain sebagai alternatif agar hasil belajar matematika siswa meningkat.
