Abstract

Abstract: The ability of students to use Information and Communication Technology (ICT) is still not optimally integrated with learning. Even though most students already have gadgets, internet connections are available via campus hotspots. Based on this, learning in higher education cannot be separated from the use of computerized and online-based technology. The integration of ICT into vclass-based multimedia learning is a potential thing to develop. This vclass-based multimedia application is expected to improve habits of mind and conceptual understanding of biology cell of students. Improved learning outcomes can be demonstrated through conceptual understanding which are the ability to understand the concepts that exist in the learning material after the learning process takes place.Keywords: habits of mind, mastery of concepts, cells, virtual class. Abstrak: Kemampuan mahasiswa dalam menggunakan Teknologi Informasi dan Komunikasi (TIK) masih belum optimal diintegrasikan dengan pembelajaran. Padahal sebagian besar mahasiswa sudah memiliki gadget, tersedia koneksi internet melalui hotspot kampus. Berdasarkan hal tersebut, pembelajaran di perguruan tinggi tidak bisa terlepas dari pemanfaatan teknologi yang terkomputerisasi dan berbasis online. Integrasi TIK ke dalam pembelajaran melalui multimedia berbasis vclass merupakan hal yang potensial untuk dikembangkan. Penerapan multimedia berbasis vclass ini dapat meningkatkan habits of mind dan penguasaan konsep sel mahasiswa pendidikan biologi. Peningkatan hasil belajar dapat ditunjukkan melalui penguasaan konsep yang merupakan kemampuan memahami konsep-konsep yang ada dalam materi pembelajaran setelah proses pembelajaran berlangsung.Kata kunci: habits of mind, penguasaan konsep, sel, kelas virtual.DOI: http://dx.doi.org/10.23960/jpmipa/v20i1.pp17-22

Abstract

Mathematical proof is one of the mathematical abilities that is very important for students. Until now, most students had difficulty in mathematical proof. The difficulty of this mathematical proof needs to be analyzed the causes, including analysis based on gender differences. This qualitative research aims to describe the ability of mathematical proof based on gender difference. The research subjects were students of mathematics education FKIP Lampung University taking the introduction to group theory in the odd semester of the academic year 2019/2020. Research subjects were 30 people, consisted of 7 men and 23 women. Data was collected through tests and observations, and it were analyzed descriptively based on 3 indicator levels, namely fluency, flexibility, and originality. The results showed that the mathematical proof ability of students were 1.80 (medium); men was 1.43 (medium) and female was 1.87 (medium), and men reach originality. So, it is concluded that the mathematical proof ability of students is medium, women are higher than men in fluency and flexibility, but men are higher than women in originality. Keywords: Mathematical proof, the introduction to group theory, gender differences

Abstract: The Effectiveness of the Problem Based Learning Model Viewed from the Students Understanding of Mathematical Concepts. This study aimed to find out the effectiveness of the Problem Based Learning (PBL) model in terms of students understanding mathematical concepts. The population of this study was all seventh grade students of SMP Negeri 3 Natar in the even semester of the academic year of 2018 2019 as many as 126 students that distributed into four classes. Two classes were randomly taken as samples with one class as the experimental class and one class as the control class. This study used the randomized pretest posttest control group design. The research data was obtained through a essay test of the comparison. The results showed the increasing of students understanding of mathematical concepts who took PBL was higher than increasing of students understanding of mathematical concepts of who took conventional learning, but the proportion of students who had a well defined mathematical concept was not more than 60 percent of students who took PBL. Thus, PBL was not effective in terms of students understanding mathematical concepts.Keywords: effectiveness, understanding mathematical concepts problem based learning  Abstract: Efektivitas Model Problem Based Learning  Ditinjau Dari Pemahaman Konsep Matematis Siswa. Penelitian ini bertujuan untuk mengkaji efektivitas model Problem Based Learning (PBL) ditinjau dari  pemahaman konsep matematis siswa. Populasi penelitian ini adalah seluruh siswa kelas VII SMP Negeri 3 Natar semester genap tahun pelajaran 2018 2019 sebanyak 126 siswa yang terdistribusi ke dalam empat kelas. Dua kelas diambil secara acak sebagai sampel dengan satu kelas sebagai kelas eksperimen dan satu kelas sebagai  kelas kontrol. Penelitian ini menggunakan the randomized pretest posttest control group design. Data penelitian diperoleh melalui tes uraian pada materi perbandingan. Hasil penelitian menunjukkan peningkatan pemahaman konsep matematis siswa yang mengikuti PBL lebih tinggi dari pada peningkatan pemahaman konsep matematis siswa yang mengikuti pembelajaran konvensional, tetapi proporsi siswa yang memiliki pemahaman konsep matematis terkategori baik tidak lebih dari  banyaknya siswa yang mengikuti PBL. Dengan demikian, PBL tidak efektif ditinjau dari pemahaman konsep matematis siswa.Kata kunci: efektivitas, pemahaman konsep matematis, problem based learning DOI: http://dx.doi.org/10.23960/jpmipa/v19i1.pp1-12
