Abstract

AbstrakPenelitian ini dilatarbelakangi oleh lemahnya  penggunaan media pembelajaran di sekolah. Guru sebenarnya sudah pernah menggunakan media pembelajaran berbasis komputer yaitu Microsoft power point tetapi belum mendapatkan hasil optimal untuk meningkatkan pemahaman siswa. Tujuan penelitian ini adalah  mengembangkan media pembelajaran matematika pada materi aritmatika sosial menggunakan video berbasis Powtoon untuk siswa kelas VII SMP Negeri 9 Muaro Jambi yang memenuhi aspek kevalidan dan kepraktisan. Penelitian ini merupakan penelitian pengembangan (RD). Model penelitian yang digunakan adalah ADDIE, yang terdiri dari 5 tahapan yaitu: 1)Analisis, 2)Perancangan, 3)Pengembangan, 4)Pelaksanaan, dan 5)Penilaian. Hasil penelitian menunjukkan bahwa kualitas media pembelajaran berdasarkan penilaian: 1)ahli desain diperoleh hasil rata-rata 4  atau kategori “Baik” atau mendapat nilai 80% atau kategori “Layak”. 2)ahli materi diperoleh total rata-rata 4,4  atau kategori “Sangat Baik” atau mendapat nilai 88% atau  kategori “Sangat Layak”. 3)ahli media diperoleh total rata-rata 3,9  atau kategori “Baik” atau mendapat nilai 79% atau kategori “Layak”. Penilaian oleh siswa dilakukan dalam 3 tahap: 1) uji coba perorangan diperoleh rata-rata 4 atau kategori “Baik” atau mendapat nilai 80% atau kategori “Sangat Layak”. 2)uji coba kelompok kecil diperoleh total rata-rata 4 atau kategori “Baik” atau mendapat nilai 80% atau kategori “Sangat Layak”. 3)uji coba lapangan diperoleh total rata-rata 4,2 atau kategori “Sangat Baik” atau mendapat nilai 85% atau kategori “Sangat Layak”. Dengan demikian media pembelajaran Powtoon pada materi aritmatika sosial ini dinyatakan valid,  praktis sehingga layak digunakan.Kata Kunci: Video Pembelajaran, powtoon. AbstractThis research is motivated by the weak use of learning media in schools. Actually, teachers have used computer-based learning media, namely Microsoft power point, but have not gotten optimal results to improve student understanding. Meanwhile, the purpose of this research is to develop mathematics learning media on social arithmetic material using Powtoon-based video for seventh grade students of SMP Negeri 9 Muaro Jambi which meets the aspects of validity and practicality. This research is a development research (RD). The research model used is ADDIE, which consists of 5 stages, namely: 1) Analysis, 2) Design, 3) Development, 4) Implementation, and 5) Assessment. The results showed that the quality of learning media based on the assessment of: 1) design experts obtained an average result of 4 or the "Good" category or  it scored 80% or the "Decent" category. 2) the material expert obtained a total average of 4.4 or the "Very Good" category or it gets a score of 88% or the "Very Eligible" category. 3) media experts obtained a total average of 3.9    or the "Good" category or it gets a score of 79% or the "Decent" category. The assessment by students was carried out in 3 stages: 1) individual trials obtained an average of 4 or the "Good" category ot it gets a score of 80% or the "Very Eligible" category. 2) the small group trial obtained a total average of 4 or the "Good" category if the percentage received a score of 80% or the "Very Eligible" category. 3) the field trial obtained a total average of 4.2 or the "Very Good" category or it gets a score of 85% or the "Very Eligible" category. Thus the Powtoon learning media on this social arithmetic material is declared valid, practical so that it is feasible to use. Keywords : Learning Video, powtoon.

Abstract

ABSTRACTThe purpose of this study is to determine whether there is a difference in the ability to understand the mathematical problems of students through the VAK learning model using VCD and print learning media. This type of research is an experiment using pretest-posttest control design. The sample of this study were three classes, 2 experimental classes and 1 control class. The results showed that the average value of student learning outcomes through the VAK learning model using VCD learning media in the initial test was 46.31 while in the final test it was 83.56; the average value of student learning outcomes through the VAK learning model using print learning media (LKS) in the initial test of 37.31 while in the final test amounted to 72.21; and the average value of student learning outcomes through the conventional VAK learning model in the initial test was 45.34 while the final test was 55.5. The results of the values of these three classes were tested statistically using One way Anava at significant (α = 5%) to determine whether there were differences. From the results of the one way anava test there was a significant difference between the VAK learning model using VCD learning media, the VAK learning model using printed learning media (LKS), and conventional learning models. Keywords: Visualization, Auditory, Kinesthetic (VAK) Learning Models, Mathematical Problem Solving Capabilities, VCD Learning Media

Abstract

ABSTRAKThis research is an experimental research, while the problem formulation in this study is the Problem Posing learning model is effective against the results of learning straight line equation material in class VIII of SMP Negeri 3 Pagaralam. This study aims to determine the effectiveness of the Problem Posing model for student learning outcomes in the material of Straight Line Equations in Class VIII of SMP Negeri 3 agaralam, with a sample of students including 21 experimental class students and 21 control class students, to measure student mathematics learning outcomes in research This is a written test in the form of essays which amounts to 5 questions. The hypothesis of this research is that the Problem Posing learning model is effective on the learning outcomes of straight-line equations in class VIII of SMP Negeri 3 Pagaralam. The results of students' mathematical test data with the Problem Posing learning model obtained an average of 70.5 and the average mathematics learning outcomes of students not with the Problem posing model of 65.08. By using the t-test statistical formula, we obtained a tcount of 3.50 and a table price of 1.725 with a significance level of 5%. So it can be concluded that the hypothesis formulated by researchers proved to be accepted, namely the Effective Problem Posing learning model for solving straight line equation problems in class VIII of SMP Negeri 3 Pagaralam. Keywords: Problem Posing learning model, Student Learning
