PEMBELAJARAN KOOPERATIF TIPE MAKE A MATCH UNTUK MENINGKATKAN AKTIVITAS DAN PEMAHAMAN KONSEP SISWA SMP
No full textPenyebab rendahnya aktivitas dan pemahaman konsep siswa didasarkan pada aktivitas siswa dalam belajar matematika masih pasif, dan pemahaman konsep siswa kurang dalam proses belajar-mengajar dikelas. Secara umum, gurulah yang lebih mendominasi dalam kegiatan belajar mengajar sedangkan aktivitas siswa hanya terbatas pada mendengar, mencatat dan menjawab suatu pertanyaan apabila guru memberikan pertanyaan, kurangnya aktivitas siswa dalam belajar akan berpengaruh juga pada rendahnya pemahaman siswa terhadap materi matematika sehingga mempengaruhi hasil belajar siswa menjadi rendah. Oleh karena itu, diperlukan perbaikan pembelajaran yang menekankan pada adanya aktivitas, interaksi, dan peningkatan pemahaman konsep matematika siswa. Penelitian ini bertujuan untuk meningkatkan aktivitas dan pemahaman konsep siswa kelas VII SMP Negeri 3 Praya melalui penerapan model pembelajaran kooperatif tipe Make a Match. Subjek penelitian adalah siswa kelas VII C yang berjumlah 33 siswa. Sedangkan objek penelitian adalah materi garis dan sudut, dan model pembelajaran kooperatif tipe Make a Match. Instrumen penelitian berupa lembar observasi pelaksanaan pembelajaran dan tes akhir. Hasil penelitian menunjukkan bahwa terdapat peningkatan aktivitas dan pemahaman konsep siswa dari setiap pertemuan yang dilaksanakan. Berdasarkan hasil analisis data aktivitas siswa berkategori dari aktif menjadi sangat aktif sedangkan hasil analisis data evaluasi pemahaman konsep siswa memiliki presentase ketuntasan 21,21% meningkat menjadi 87,10%. Dengan memperhatikan hasil analisis data, maka dapat disimpulkan bahwa model pembelajaran kooperatif tipe Make a Match dapat meningkatkan aktivitas dan pemahaman konsep siswa kelas VII SMP Negeri 3 Praya

PENGARUH EKSTRAK Sargassum cristaefolium PADA MULTIPLIKASI Dendrobium antennatum Rchb.f SECARA IN VITRO
Get PDFThe purpose of this study was to determine the potential and concentration of Sargassum cristaefolium extract as a natural cytokinin in tissue culture media of Dendrobium antennatum Rchb.f. This study is experimental with a completely randomized design, using several extract concentrations compared with the positive control (BAP 1.5 ppm) and negative control (MS0 media). Extract concentrations used 5 ppm, 10 ppm, 15 ppm, 20 ppm, and 25 ppm. Based on analysis of variance (ANOVA), the effect of Sargassum cristaefolium extract on the growth media significant on all parameters. Sargassum cristaefolium extracts caused different responses at certain levels of concentration. Extract concentration of 10 ppm was able to initiate the highest number of shoots and leaves compared to other extract concentrations, where as the concentration 20 ppm was able to accelerate and increase root growth
Analysis of the Ability of Junior High School Students to Solve the Physics Problems in Various Forms of Problem Representations
Get PDFThis research is a descriptive study with a qualitative approach, which aims to describe the ability of junior high school students to solve physics problems in various forms of problem representation. The subjects in this study were the IX grade junior high school students in six Palu city schools. Respondents for interviews in the study amounted to 4 people for each form of problem representation, with the criteria of students who answered right, students who answered ± 50% correct, students who answered incorrectly, and who did not answer. The instrument used was a test of problem solving skills and interviews. The data obtained were analyzed qualitatively including data reduction, presenting data and verification while descriptive analysis was performed by calculating the total score, calculating the percentage and categorizing problem solving abilities. The results obtained by the average ability of junior high school students to solve physics problems in various forms of problem representation 21.86% (less category), with the percentage of each form of representation ie verbal representation 36.09% (less category), image/picture representation 23.78% (less category), diagram representation 19.47% (poor category) and graphic representation 8.10% (poor category)
Inovasi Pemanfaatan Teknologi Sebagai Media Pembelajaran di Era Revolusi 4.0
Get PDFThis study aims to examine the use of technology technique as a learning media and teacher innovation to overcome the problem. By library research, the researcher conducted the relevant literature study to answer the research and explained it descriptively. The results of the study indicate that optimization on the use of instructional media was done by understanding the characteristics of media and learning needs. Technology controller was the teacher, not the teacher depending on technology. Teacher needs innovation when facing the limitations or facing other technical obstacles. Teacher can maximize everything that can be used to deliver learning information, including the use of the environment. So, something real can be presented applicatively

Pengembangan E-Learning dengan Metode Self Assessment Untuk Meningkatkan Hasil Belajar Matematika Mahasiswa Universitas Mahendradatta
Get PDFThis study is aimed to develop e-learning media with self-assessment methods to improve mathematics learning outcomes of college students. The model used in the development of e-learning was the ADDIE model. The sample of this study was 39 college students of the Industrial Engineering Program, Faculty of Engineering, Mahendradatta University. The data analyzed in this study were student’s mathematics learning outcomes obtained from the posttest scores after using e-learning with self assessment method. To determine the effectiveness of the implementation of e-learning, experimenation with one group pretest and posttest design was conducted. Data of learning outcomes obtained were analyzed by using the Paired T-Test. Based on the results of expert validation and product trials, e-learning was feasible to be implemented. Based on the results of the Paired T-Test, a significant value of less than 0.05 was obtained, so based on the hypothesis that there was a difference between the learning outcomes before and after e-learning was implemented. This was also supported by an increase in the average value of student mathematics learning outcomes, from the initial pretest score of 75,92 to 82,10. Student response value was 69,0 which indicated that the response to e-learning was positive. The increase in learning outcomes was due to e-learning learning with self-assessment methods which provided opportunities for students to increase their confidence in their mathematical skills
Efektivitas Penggunaan Media Tiga Dimensi Dalam Meningkatkan Kemampuan Mengenal Benda pada Siswa Tuna Netra
Get PDFBlindness is a disturbance that occurs in a person's vision, in the form of complete or partial blindness, resulting in malfunctioning of vision. The difficulty in recognizing objects in blind students is due to the lack of media used in the learning process, the media used must be in accordance with the deficiencies experienced by students, namely not being able to see objects but requiring media that can be touched directly by students. Therefore we need media that can support the learning process in this case, namely three-dimensional media. The formulation of the problem of this research is whether there is an effectiveness of using three-dimensional media in increasing the ability to recognize objects for blind students. While the aim is to determine the effectiveness of using three-dimensional media in improving the ability to recognize objects for blind students. The type of this research is using quantitative descriptive methods. The method used to obtain data in this study is a test method and data analysis method using t-test analysis. Based on the results of the data analysis carried out, before using three-dimensional media from 23 students from 3 classes only 10 students completed and in each class there were 3-4 students who completed after the use of three-dimensional media in the learning process increased student learning completeness. Of the 23 students in 3 different classes 19 students were declared complete with an average grade of 7-8 students, this proved a very significant increase
