Abstract

Media pembelajaran ialah suatu alat yang membantu untuk proses pembelajaran berfungsi memperjelas makna pesan atau informasi ingin disampaikan, sehingga mencapai tujuan pembelajaran yang telah direncanakan. Penelitian ini bertujuan untuk memperoleh media pembelajaran learning management system berbasis problem based learning (PBL) Pada materi balok dan kubus untuk siswa smp kelas VIII yang layak dilihat dari aspek kevalidan, kepraktisan dan keefektifan. Jenis penelitian ini adalah Research and Development model ADDIE. Hasil penelitian menunjukkan bahwa dilihat dari aspek kevalidan, penilaian validator materi adalah 4,22 sedangkan penilaian validator media adalah 4,15 yang termasuk dalam kategori sangat layak. Berdasarkan aspek kepraktisan, hasil respon penilaian peserta didik terhadap uji coba kelompok kecil adalah 4,08 termasuk kategori praktis dan aspek keefektifan hasil respon penilaian peserta didik terhadap uji coba kelompok besar adalah 4,15 termasuk kategori efektif. Dengan demikian, dapat disimpulkan bahwa media pembelajaran learning management system (LMS) berbasis problem based learning (PBL) Pada materi balok dan kubus untuk siswa smp kelas VIII dinyatakan layak sebab valid, praktis dan efektif digunakan dalam proses pembelajaran.Kata Kunci: Media pembelajaran, e-Learning, problem based learning. ABSTRACTLearning media is a tool that helps the learning process function to clarify the meaning of the message or information to be conveyed, so as to achieve the planned learning objectives. This study aims to obtain a learning management system based on problem based learning (PBL) media on block and cube material for class VIII junior high school students that is feasible from the aspect of validity, practicality and effectiveness. This type of research is Research and Development model ADDIE. The results showed that from the aspect of validity, the material validator's assessment was 4.22 while the media validator's assessment was 4.15 which was included in the very feasible category. Based on the practical aspect, the results of the student's assessment response to the small group trial were 4.08 including the practical category and the effectiveness aspect of the student's assessment response to the large group trial was 4.15 including the effective category. Thus, it can be concluded that the learning management system (LMS) learning media based on problem based learning (PBL) on block and cube material for class VIII junior high school students is declared feasible because it is valid, practical and effective to use in the learning process.Keywords: Learning media, e-Learning, problem based learning.

Abstract

AbstractThis study was carried out (1) to improve students mathematical problem solving ability through mathematics learning approach at the eight grade students of SMP Negeri 17 Medan T.A 2015/2016, (2) to find the improvement of students mathematical problem solving ability through mathematics learning approach at the eight grade students of SMP Negeri 17 Medan T.A 2015/2016. The participants of this study were the 32 students of VIII-2 class of SMP Negeri 17 Medan and the objective of the study was improving students mathematical problem solving ability in prism an limas subject. The method of this study was classroom action research. The instruments of this study were test and observation. This study was consisted of two cycles; each cycle consisted of two meetings. The improvement of the problem solving ability could be seen from each step of problem solving in the intial capability test, problem solving ability test I and problem solving solving ability test II. In the step of problem solving, the score in the initial capability test was 59,20 (low), problem solving ability test I was 80,08 (high), problem solving ability test II was 89,45 (high). In the step of  constructuring plan of problem solving, the score in the initial capability test was 45,80 (very low), problem solving ability test I was 72,88 (average), problem solving ability test II was 81,47 (high). In the step of doing plan of problem solving, the score in the initial capability test was 52,05 (low), problem solving ability test I was 78,61 (average), problem solving ability test II was 85,38 (high). In the step crosscheck, the score in the initial capability test was 29,69 (very low), ), problem solving ability test I was 71,48 (average), problem solving ability test II was 81,25 (high). So, it was obtained that the lowest step in the problem solving ability was the step of crosscheck. Furhermore, the ability of the researcher in managing lessons increased from cycle I to cycle II. In pre-activity 2,63 became 3,12. In main activity 2,47 became 3,05. In post-activity 2,75 became 3,75. So, it was concluded that realistic mathematics learning approach did improve the mathematical problem solving ability of the eight students of SMP Negeri 17 Medan in prism and limas subject.Kata kunci : realistic mathematics learning approach, problem solving

Abstract

AbstrakThis article is a report of trialing PISA problems designed in secondary school. This report explores students’ strategies in solving PISA problems which has three criterion, namely content, context and competencies. Hopefully, first, they should be usual with the PISA problems related to description of the situation and the students have to discover and solve the problems with their own strategies. Second, they can solve the problem without require applying formulas or procedures, so that they have sense to mathematics.Keyword: PISA Problem
