SIGNIFIKANSI PERBEDAAN PRESTASI BELAJAR MATEMATIKA YANG DIAJAR DENGAN PEMBELAJARAN MODEL KOOPERATIF TIPETHINK PAIR SHARE (TPS) DANMODEL PEMBELAJARAN EKSPOSITORI PADA SISWA KELAS VIII SMP NEGERI 3 SUKAWATI TAHUN AJARAN 2015/2016

Menyadari bahwa secara teori pembelajaran model kooperatif tipe think pair share (TPS) mempunyai keunggulan pada proses mental dibandingkan dengan model ekspositori maka penelitian dengan judul seperti tersebut di atas tertarik untuk dilakukan. Penelitian ini adalah penelitian eksperimen dengan desain penelitian menggunakan “posttest-only control design”bertujuan untuk mengetahui apakah prestasi belajar matematika melalui model koopertif  tipe Think Pair Share (TPS) lebih baik secara signifikan dari pada prestasi belajar matematika darimodel ekspositori. Populasinya adalah seluruh siswa kelas VIII SMP Negeri 3 Sukawati tahun pelajaran 2015/2016 yang berjumlah 335 siswa. Sampel diambil dengan teknik cluster random sampling dengan jumlah 72 siswa (terdiri dari duakelas yaitu Siswa Kelas VIIIA dengan jumlah 36 siswa sebagai kelompok eksperimen; yang diajar dengan model pembelajaran kooperatif tipe TPS dan siswa Kelas VIIIF dengan jumlah 36 siswa sebagai kelompok kontrol; yang diajar dengan pembelajaran model  ekspositori).Data yang dikumpulkan dalam penelitian ini adalahprestasi belajar matematika siswa dalam pembelajaran Faktorisasi Suku Aljabar denganmenggunakan teknik tes dalam bentuk tes objektif sebanyak 40 soal. Tes ini sudah memenuhi syarat validitas, reliabilitas, tingkat kesukaran, dan daya beda.Dari analisis statistik deskriptif diperoleh nilai rata-rata prestasi belajar matematika dari model koopertif tipe TPS adalah 73,19 dan dari model ekspositori adalah 68,82.Karena data sampel tidak berdistribusi normal maka uji hipotesis  dianalisis dengan statistik non parametrik Mann-Whitney Testdan dilajutkan dengan uji skor Zsatu sisi, dengan taraf signifikansi 5%. Dari uji skor Z diperoleh Zhit = 2,46, sedangklan Ztabel= 1,65. Hal ini menunjukkan bahwa Zhit>Ztab. Jadi prestasi belajar matematika yang diajar dengan pembelajaran model kooperatif tipe think pair share (TPS) lebih baik secara signifikan dari prestasi belajar matematika yang diajar dengan  Pembelajaran model ekspositori pada siswa kelas VIII SMP Negeri 3 Sukawati tahun pelajaran 2015/2016

STUDI KASUS TENTANG KEMAMPUAN ANALISIS MAHASISWA PADA KONSEP HARGA MUTLAK

This research is about case study which aimed to describe the ability of analysis thinking of student on absolute value concept. The ability data of analysis tinking student is collected by using essay test technic. The assessment of the answer test is corrected by using rubric assessment of analysis tinking ability. Facted, the obtaining score of student was 6 from 20 maximal ideal. Therefore, the conclution of the ability of analysis tinking of student is . This ability is very poor level. The causing of this poor level is guessed from internal factor in the form of lagging perceptual span so that the information process become uncomplete, and from the external factor in the form of interference learning environments

Classroom action research practices of state high school teachers in Bali province

The general purpose of this study was to find out the level of difficulty in preparing Classroom Action Research (CAR) Proposals, implementation and report writing of classroom action research conducted by state high school teachers in Bali Province. The present study was designed for two years, the study adopted the 4D model (Define, Design, Develop, and Disseminate). The first year (2018) was defined as the phase of Define and Design, which aims to design CAR proposals in line with the Lesson Plan (LP), the implementation of CAR by state high school teachers and report writing linear with List of Proposed Establishment of Credit (LPEC). The second year (2019) was the Development and Dissemination phase. The activities in this phase were (a) enhancing the development and improvement of CAR of state high school teachers in accordance with the proposal model, the CAR implementation model designed based on LP and CAR report model through Focus Group Discussion (FGD) which was attended by High School Teachers, High School Principals, High School Supervisors, LPEC High School Teachers Team, and the CAR participants from the Department of Education and Sport, Bali Province. The results of the second year research were the CAR proposals were linear with teachers’ LP, Classroom LP implementation, learning schedule, and CAR report writings were linear with LPEC and publication on international journal and textbook writings
