Abstract

The pre-experimental research with The Static-Group Pretest-Posttest Design design aims to describe the improvement of students' reasoning ability through the erosion-based e-learning problem model and to describe students' scientific attitudes through erosion-based enamel-based learning. The sample in this research is class XI MIA 3 as experiment class and class XI MIA 9 as control class at one of SMA Negeri in Bandar Lampung. The result of the research on improving reasoning ability, shown by the average difference of n-Gain students' reasoning ability of experimental class is significantly higher than control class. Scientific attitudes described, shown by the trained students' scientific attitude during the learning in accordance with the rubric that has been made researchers. The conclusion of this research is learning with Problem Based Learning model can improve students 'reasoning ability and also to train students' scientific attitude.Penelitian pre-eksperimen dengan desain penelitian The Static-Group Pretest-Posttest Design ini bertujuan untuk mendeskripsikan peningkatan kemampuan penalaran siswa melalui model pembelajaran berbasis masalah erosi email gigi dan untuk mendeskripsikan sikap ilmiah siswa melalui pembelajaran berbasis masalah erosi email gigi. Sampel dalam penelitian ini adalah kelas XI MIA 3 sebagai kelas eksperimen dan kelas XI MIA 9 sebagai kelas kontrol di salah satu SMA di Bandar Lampung. Hasil penelitian peningkatan kemampuan penalaran, ditunjukkan oleh perbedaan rata-rata n-Gain kemampuan penalaran siswa kelas eksperimen secara signifikan lebih tinggi daripada kelas kontrol. Sikap ilmiah yang dideskripsikan, ditunjukkan berdasarkan terlatihnya sikap ilmiah siswa selama pembelajaran sesuai dengan rubrik yang telah dibuat peneliti. Kesimpulan penelitian ini adalah pembelajaran dengan model Pembelajaran Berbasis Masalah dapat meningkatkan kemampuan penalaran siswa serta melatih sikap ilmiah siswa.Kata Kunci: kemampuan penalaran, sikap ilmiah siswa, model pembelajaran berbasis masalah, titrasi asam basa

Abstract

Abstract: Development of Interactive E-Book Based on Chemical Representation on Electrolysis Cell Topic. This research was aimed to develop an interactive e-book and describe its characteristics and validity as well as to describe the teachers’ and students’ responses of interactive e-book was developed. The research design used Borg and Gall method of research and development which only carried out until the fifth stage, namely the revision stage of the trial results. The data obtained were analyzed using descriptive statistical analysis. Characteristics of interactive e-book based on chemical representation of the electrolysis cell topic was developed, starting with discourses related to everyday life phenomena accompanied by pictures based on chemical representation, equipped with identification columns, explanation columns, observation tables and interactive questions. The results of expert validation on the aspects of content suitability, construction and readability all have very high criteria. Based on this, the interactive   e-book based on the chemical representation on electrolysis cell topic is said to be valid. In addition, the results of the teacher's responses to aspects of the suitability of content, construction and readability as well as the results of student responses to aspects of attractiveness and readability each have very high criteria.                                                                Keywords: interactive e-book, chemical representation, electrolytic cell
