Abstract


Abstract: Improving Students' Ability to Understand Chemical Representations through the Implementation of a Web-Based E-Module on The Periodic System of Elements Materials. The study’s objective was to improve learner’s ability to understand chemical representation and learning outcomes by implementing web-based E-Module on periodic system of elements material. The type of research is development research (R & D) with a four steps model (4D) but only limited to the third stage namely develop stage. This research is a part of the development stage, namely limited trials using a quantitative descriptive method with the type was pre experimental with one group pretest-posttest design. This research was carried out in SMA Al-Islam Krian Sidoarjo region with the subject of the study, to be specific 18 students of class XI MIPA. The research data was obtained from the test of learning outcomes. Data was analysed by Wilcoxon test and N-gain. The result showed that the learner's ability to understand chemical representation was improve after using Web-Based E-Module proceeded with Wilcoxon test because the data was not normally distributed and obtained the Asymp. Sig. (2-tailed) value was 0,000. Based on N-gain score was obtained a range 0,69 – 1 with medium or high criteria. Therefore, the implementation of web-based E-Module can be an alternative solution to improve the learner’s ability to understand chemical representation.

 

Keywords: Web, E-Module, chemical representation.

 

Abstrak:Peningkatan Kemampuan Peserta Didik untuk Memahami Representasi Kimia melalui Implementasi E-Modul Berbasis Web pada Materi Sistem Periodik Unsur. Penelitian ini bertujuan untuk meningkatkan kemampuan peserta didik memahami representasi kimia dan hasil belajar dengan mengimplementasikan E-Modul berbasis web pada materi sistem periodik unsur. Jenis penelitian ini merupakan penelitian pengembangan (R & D) dengan model 4D namun hanya terbatas pada tahap ketiga yaitu tahap pengembangan (develop). Penelitian ini merupakan bagian dari tahap pengembangan yaitu uji coba terbatas dengan menggunakan metode deskriptif kuantitatif dengan jenis pra-experimental one group pretest-posttest design. Penelitian dilakukan di SMA Al-Islam Krian Sidoarjo dengan subjek penelitian sebanyak 18 siswa kelas XI MIPA. Data penelitian diperoleh dari tes hasil belajar. Data dianalisis dengan uji Wilcoxon dan N-gain. Hasil penelitian menunjukkan bahwa kemampuan peserta didik dalam memahami representasi kimia meningkat setelah menggunakan E-Modul Berbasis Web yang dilanjutkan dengan uji Wilcoxon karena data tidak berdistribusi normal, dan mendapatkan nilai Asymp. Sig (2-tailed) sebesar 0,000. Berdasarkan nilai N-gain diperoleh nilai 0,86 dengan kriteria tinggi. Oleh karena itu, implementasi E-Modul berbasis web mampu menjadi solusi alternatif untuk meningkatkan kemampuan peserta didik dalam memahami representasi kimia.
