It means t-test for the use of teaching material was equal to 3,586 with sig. of α = 0.005, t = 2.704. The value of t arithmetic less than t table (3.586> 2.704). It was said that the props of scrap materials improved students' understanding of the concept. The indicator for the concepts include memorizing, understanding, and applied to show that there was increasing in the value of the pre-test and post-test the student.
The purpose of this research is to determine: (1) the difference of the science process skills of students learning using group workshop method with students using the discussion method; (2) PENDAHULUANPerubahan jaman dan tuntutan masyarakat mendorong peningkatkan kualitas pendidikan untuk mampu menghasilkan sumber daya manusia yang berkualitas dan mampu bersaing. Sebagaimana yang diungkapkan oleh Mulyasa (2009:4), dalam tataran mikro pendidikan harus mampu menghasilkan sumber daya manusia yang berkualitas dan profesional, termasuk di dalamnya kebutuhan dunia kerja dan respon terhadap perubahan yang terjadi dalam masyarakat. Upaya untuk meningkatkan mutu pendidikan membutuhkan proses pembelajaran yang optimal sehingga tercapai tujuan yang diharapkan.Menurut UU No. 23 Tahun 2003 tentang Sistem Pendidikan Nasional, pembelajaran adalah proses interaksi peserta didik dengan pendidik dan sumber belajar pada suatu lingkungan belajar. Pembelajaran merupakan proses penyediaan kondisi yang mengakibatkan terjadinya interaksi dalam proses belajar pada diri peserta didik dengan guru. Upaya untuk mengembangkan kompetensi peserta didik memerlukan adanya kerjasama antartiap komponen dalam dunia pendidikan untuk mencapai niat tersebut.
