Abstract


Tujuan penelitian ini adalah untuk menganalisis penguasaan materi dan keterampilan berpikir kreatif mahasiswa setelah mengikuti perkuliahan Kimia Lingkungan berbasis masalah untuk materi pencemaran udara. Penelitian dilakukan terhadap mahasiswa Program Studi Pendidikan Kimia di salah satu universitas di Semarang untuk mata kuliah Kimia Lingkungan pada semester genap tahun 2010-2011. Mahasiswa rombel 1 (20 orang) untuk kelas eksperimen diberi perkuliahan dengan pendekatan berbasis masalah. Rombel 2 (23 orang) untuk kelas kontrol diberi perkuliahan seperti yang biasa dilakukan selama ini. Data yang terkumpul selanjutnya dilakukan analisis secara deskriptif. Has ii penelitian menunjukkan N-gain penguasaan materi pencemaran udara mahasiswa kelompok eksperimen adalah sedang, demikian pula untuk kelompok kontrol. N-gain keterampilan berpikir kreatif untuk kelas eksperimen adalah tinggi, sedangkan untuk kelompok kontrol adalah sedang. Lebih dari 50% pendapat mahasiswa menyebutkan bahwa komponen materi, model, pedoman mahasiswa, LKM, suasana belajar dan strategi dosen dalam perkuliahan sangat menarik, sangat baru, dan sangat mudah. Agar N gain rerata kelompok eksperimen dan kelompok kontrol pada indikator 3 tidak mengalami peningkatan paling sedikit, maka mahasiswa lebih dimotivasi dalam mencari sumber mutakhir tentang penyelesaian masalah pencemaran udara.

The purpose of this study was to analyze students' material mastery and creative thinking skills after attending Environmental Chemistry-based lectures for a material issue of air pollution. This study was conducted on students of Chemistry Education at a university in Semarang for Environmental Chemistry courses in the second semester 2010-2011. Students of class 1 (20 people) as the experimental group were treated with a problem based approach. Class 2 (23 people) as the control group were treated with lectures as was done during this time. The collected data were then analyzed descriptively. The results showed that N -gain of matter mastery of air pollution of experimental group was moderate, as well as for the control group. N-gain of creative thinking skills for the experimental class was high, whereas for the control group was moderate. More than 50% of students said that the material component, models, students' guidance and creativity sheets, an atmosphere of learning, and lecturer's strategy in the lecture were very interesting, very new, and very easy. In order to gain the mean N-gain of the two groups at the third indicator did not have the least increase, the students were more motivated to look for on the newest source of air pollution problems.
