Analysis of Mathematics Problem Solving Ability of Junior High School Students in Solving Problems in Online Learning

This study aims to determine the mathematical problem solving ability of students in solving story problems with online learning. The method in this study used a qualitative descriptive research method. The results showed that there were differences in the ability to identify the elements that were known and asked, there were differences in the ability to choose and apply strategies or problem solving procedures and there were differences in the ability to examine and explain the results or answers according to problems between students with high, medium mathematical problem solving abilities. and low. There are 43% of students who have been able to follow and adapt online learning while 57% of other students have difficulty understanding the material being taught. There are 60.86% of students who have a high enough enthusiasm in online learning (online) but 39.13% of students are not happy if learning mathematics is done online due to factors that influence it such as technical constraints. There are 73.91% of students with a positive response to the problem of mathematical problem solving ability even though the learning is carried out online and 26.08% of students with a negative response

Advanced Refrigerator/Freezer Technology Development. Technology Assessment

The NASA Lewis Research Center, through contract with Oceaneering Space Systems, is engaged in a project to develop advanced refrigerator/freezer (R/F) technologies for future Life and Biomedical Sciences space flight missions. The first phase of this project, a technology assessment, has been completed to identify the advanced R/F technologies needed and best suited to meet the requirements for the five R/F classifications specified by Life and Biomedical Science researchers. Additional objectives of the technology assessment were to rank those technologies based on benefit and risk, and to recommend technology development activities that can be accomplished within this project. This report presents the basis, the methodology, and results of the R/F technology assessment, along with technology development recommendations

Pengembangan Perangkat Pembelajaran untuk Meningkatkan Kemampuan Pemecahan Masalah Matematis Siswa SMP Negeri 12 Pematangsiantar

Tujuan dari penelitian ini untuk mengetahui: (1) Bagaimana kualitas perangkat pembelajaran yang dikembangkan dengan model pembelajaran berdasarkan masalah untuk meningkatkan kemampuan pemecahan masalah matematis siswa, dan (2) Bagaimana peningkatan kemampuan pemecahan masalah matematis siswa dengan menggunakan perangkat pembelajaran yang dikembangkan. Perangkat pembelajaran yang dikembangkan adalah buku guru, buku siswa, RPP, LAS, dan instrumen tes kemampuan pemecahan masalah. Populasi dalam penelitian ini adalah seluruh siswa kelas VII SMP Negeri 12Pematangsiantar T.A. 2014/2015, dengan mengambil sampel dua kelas yang berjumlah 70 siswa. Penelitian ini merupakan penelitian pengembangan dengan menggunakan model pengembangan Thiagarajan, Semmel dan Semmel, yaitu model 4D yang telah dimodifikasi. Proses pengembangan tersebut terdiri dari empat tahap, yaitu: define, design, develop dan disseminate. Hasil analisis data yang telah diperoleh menunjukkan bahwa kualitas perangkat pembelajaranyang dikembangkan dengan model pembelajaran berdasarkan masalah pada materi persamaan dan pertidaksamaan linear satu variabel di kelas VII SMP Negeri 12 Pematangsiantar adalah baik ditinjau dari valid, praktis dan efektif. Terjadi peningkatan kemampuan pemecahan masalah matematis siswa dengan menggunakan perangkat pembelajaran yang dikembangkan

WORKSHOP PENGEMBANGAN MEDIA PEMBELAJARAN BAHASA INGGRIS BERBASIS INFORMASI DAN TEKNOLOGI DI SMA NEGERI 1 SIDAMANIK

Tujuan dari kegiatan Pengabdian ini adalah untuk melatih dan meningkatkan kemampuan guru-guru  SMA Negeri 1 Sidamanik kabupaten Simalungun Sumatera Utara dalam mengembangkan pembelajaran media bahasa inggris  berbasis sistem informasi dan teknologi atau dikenal dengan ICT. Dari observasi dilapangan disimpulkan bahwa kemampuan guru-guru masih kurang dalam mengaplikasiskan teknologi terhadap pembelajaran dikelas masing masing dengan menggunakan ICT. Hampir semua guru-gurunya tidak memahami untuk menggunakan media teknlogi dalam proses pembelajaran baik tugas dan mengajar kepada peserta didik. Metode yang dilaksanakan dalam kegiatan pengabdian ini terdiri dari observasi, perencanaan, persiapan, tindakan, refleksi dan evaluasi terhadap workshop pengembangan pembelajaran media bahasa inggrisi. . adapun hasil dari kegiatan pengabdian masyarakat ini yang dilaksanakan oleh dosen-dosen adalah bahwa aguru-guru mampu menguasai teknoogi seta dapat mengaplikasikannya dalam penyampaian materi-materi pembelajarna dikelas. Kemudian meningkatakan wawasan tenta pentingnya media pembelajaran yang berbasis sisteminformasi dan teknologi. Guru-guru mampu mendesain materi-materi, tugas peserta didik melalui media
