EFEKTIVITAS PEMBELAJARAN KOOPERATIF TIPE NUMBERED HEADS TOGETHER TERHADAP HASIL BELAJAR SISWA PADA MATA PELAJARAN KESEHATAN DAN KESELAMATAN KERJA

Abstract

Abstrak

Tujuan penelitian ini untuk: (1) Mengetahui implementasi pembelajaran metode kooperatif tipe Numbered Heads Together; (2) Mengetahui sejauh mana efektivitas pembelajaran kooperatif tipe Numbered Heads Together. Jenis penelitian ini adalah penelitian eksperimen semu. Desain penelitian menggunakan Non Equivalent Control Group Design. Subjek penelitian adalah 56 siswa. Data diambil dengan instrumen test. Analisis data dilakukan dengan analisis parametrik. Hasil menunjukan bahwa: (1) Implementasi pembelajaran metode kooperatif tipe Numbered Heads Together terdapat 3 tahap yaitu: tahap pertama adalah pra penelitian, dilakukan untuk membagi siswa menjadi kelompok heterogen. Tahap kedua pemberian treatment NHT. Tahap ketiga yaitu evaluasi, tahapan ini guru bersama siswa menyimpulkan hasil diskusi; (2) Terdapat efektivitas hasil belajar pembelajaran kooperatif tipe Numbered Heads Together sebesar 0.80 termasuk dalam katagori tinggi, sedangkan menggunakan metode pembelajaran ceramah mempunyai nilai skor gain sebesar 0.62 termasuk dalam katagori sedang. Hasil uji t diperoleh thitung=4.759, ttabel=2.000 dan thitung>ttabel. Sehingga dapat disimpulkan pembelajaran kooperatif tipe Numbered Heads Together lebih meningkatkan hasil belajar K3.

Kata kunci: Hasil belajar, kesehatan dan keselamatan kerja, Numbered Heads Together.

Abstract

The purposes of the research aim to (1) obtain of implementation of cooperative learning Numbered Heads Together, (2) obtain ofthe effectiveness cooperative learning Numbered Heads Together . This research was a quasi experimental. The research design was using non-equivalent control group design. The research subject were includes 56 student. The data were collected by instrument test. The data were analyzed by paramethic analyzed. The result showed: (1) the implementation of cooperative learning method Numbered Heads Together type includes three steps : first step is pra research, done to divide the students into heterogen group. Second step gave treatment NHT.The third step is evaluation, in this step teacher with student conclude the result of the discussion;(2) There wasthe effectiveness of the learning outcomesof cooperative learning Numbered Heads Togethero f 0.80 is included in thehigh category, whileusing lecturing methodshasa scoregainof 0.62 is included in the category of being. T test results showed ttest=4.759, ttable=2.000andttest>ttable. Therefore we can concludethe cooperative learning Numbered Heads Together K3 subject improvethe learning outcomes.
