Pengaruh Model Pembelajaran Problem Based Learning Pada Mata Pelajaran Otomatisasi Tata Kelola Humas dan Keprotokolan Terhadap Hasil Belajar dan Kemampuan Berpikir Kritis Siswa Kelas XI OTKP SMK Ketintang Surabaya

The Influence of Problem Based Learning Model of Learning on the Subject of Automation in Public Relations and Protocol Management on Learning Outcomes and Critical Thinking Skills of Students in Class XI OTKP SMK Ketintang Surabaya

Abstrak

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran problem based learning pada mata pelajaran Humas dan Keprotokolan terhadap hasil belajar dan kemampuan berpikir kritis  siswa kelas XI OTKP SMK Ketintang Surabaya. Jenis penelitian eksperimen ini menggunakan quasi experimental design dengan rancangan non-equivalent control group design. Analisis data menggunakan uji normalitas, uji homogenitas, uji-t dan gain score. Hasil uji t berdasarkan nilai hasil belajar siswa menunjukkan nilai t_hitung  > t_tabel  (2,898 > 2,005) dan hasil uji-t berdasarkan nilai kemampuan berpikir kritis siswa .menunjukkan nilai t_hitung  > t_tabel (10,554 > 2,005). Kemudian selisih (gain score) nilai pre-test serta post-test diperoleh bahwa t_hitung  > t_tabel  (4,643>2,005). Dengan selisih (gain score) rata-rata nilai pre-test serta post-test kelas eksperimen 18,036 lebih besar dari nilai pre-test kelas kontrol sebesar 10,536. Sehingga dapat disimpulkan bahwa terdapat pengaruh model pembelajaran problem based learning pada mata pelajaran Otomatisasi Humas dan Keprotokolan  terhadap hasil belajar dan kemampuan berpikir kritis siswa kelas XI OTKP SMK Ketintang Surabaya.

Abstract

This study aims to determine the effect of the problem based learning model of learning in Public Relations and Protocol on learning outcomes and critical thinking skills of class XI OTKP students at SMK Ketintang Surabaya. This type of experimental research uses a quasi experimental design with a non-equivalent control group design. Data analysis used normality test, homogeneity test, t-test and gain score. T test results based on the value of student learning outcomes indicate the value of t_count> t_table (2.898>2.005) and the results of t-test based on the value of students' critical thinking skills. Show the value of t_count>t_table (10,554> 2,005). Then the difference (gain score) pre-test and post-test values ​​obtained that t_count> t_table (4.643>2.005). With the difference (gain score) the average value of the pre-test and post-test experimental class 18.036 is greater than the pre-test value of the control class of 10.536. So it can be concluded that there is an influence of  problem based learning model of learning on the subject of automation in public relations and protocol management on learning outcomes and critical thinking skills of students in class XI OTKP SMK Ketintang Surabaya.
