Pengaruh Model Problem Based Learning (PBL) Melalui Lesson Study Terhadap Kemampuan Berpikir Kritis Siswa

Abstract

This study aimed at detemining the effect of Problem Based Learning Model on the ability of students’ critical thinking through lesson on the topic of effort and energy. The method of research was an experimental research by using post-test-one control group design. Experimental class was treated by problem based learning, while the control class was taught by conventional learning through lesson study. Population of this research was the high school at Al Hamzar, Tembeng Putik of the X grade which consisted of two classes. Those were X Mathematics and natural science 1 and X Mathematics and Natural Science 2 with the total number or students was 58. The sampling thechnique applied was saturated sampling technique. Then, the instrument used in the present research was essay test which contained 6 items. The test arrangement followed the indicators of critical thinking with a variety of possible answers. Having implemented both in the experimental and in the control class, there were improvements in learning process in tems of managing the time, the students and doing aperception. Testing hyphoteshis result by uisng t-test showed t-test = 1. 25 and t-table in signifance level was 5% was 0. 07, so t-test> t-table which meant the alternative hyphothesis (Ha) was accepted and null hyphothesis (Ho) was rejected , it could be concluded that problem based learning thorugh lesson study was significantly effective in students’ critical ability on the topic of effort and energy for the tenth garade students at Al Hamzar high school.

Pengaruh Model Pembelajaran Inkuiri Terbimbing Berbantuan PhET (Physics Education Technology) Terhadap Hasil Belajar Fisika Siswa

“…Guru memerlukan perencanaan tentang model pembelajaran dan media pembelajaran yang tepat sesuai dengan karakteristik materi maupun peserta didik. Pada kenyataannya, pembelajaran fisika di kelas sangat menekankan pada aspek produk (N. Yunita et al, 2020). Pada sebagian besar pelaksanaan pembelajaran, para siswa hanya dijejali dengan konsep, prinsip, teori-teori fisika, yang tidak jarang membuat para siswa merasa berat dan bosan memahami Fisika.…”

Pengembangan Alat Peraga Fisika Sederhana Berbahan Bekas Pakai pada Materi Gerak Lurus

“…Penggunaan alat peraga dalam proses pembelajaran di kelas akan dapat memperjelas penyajian pesan, hasil belajar yang dicapai oleh peserta didik akan tahan lama diingat, dengandemikian pembelajaran mempuyai nilai yang tinggi sehingga kualitas hasil pembelajaran dapat ditingkatkan. Namun dalam hal ini penggunaan alat peraga disekolah masih sangatlah kurang (Yunita et al, 2020).…”

Penerapan Problem Based Learning (PBL) dengan Pemberian Biografi Ilmuwan Pada Mata Kuliah Fisika Dasar I: Dampak Sikap Ilmiah dan Motivasi belajar

“…Sehingga, peserta didik tidak hanya belajar mengenai pengetahuan akan tetapi merasakan dan mengalami sendiri (Khoirunisa, Rohmadi, & Yuliani, 2020). Beberapa kelebihan Model PBL antara lain berpengaruh hasil belajar (Shinta, Fatmawati, & Nasir, 2020) (Wajdi, 2018), aktivitas belajar peserta didik (Khoirunisa, Rohmadi, & Yuliani, 2020), berpengaruh terhadap berpikir kritis peserta didik (Yunita, Zahara, & Sahidi, 2020), berpengaruh terhadap sikap ilmiah peserta didik (Sunariyati, Agung, & Dantes, 2014).…”
