<![CDATA[Materi larutan elektrolit dan nonelektrolit merupakan salah satu materi kimia yang bersifat abstrak dan sulit dipahami oleh siswa. Tujuan dari penelitian ini untuk menganalisis efektivitas e-modul larutan elektrolit dan nonelektrolit berbasis guided discovery learning terhadap hasil belajar peserta didik. Jenis penelitian yang digunakan eksperimen semu dengan desain penelitian nonequivalent control group design. Populasi terdiri dari siswa kelas X MIPA dengan X MIPA 1 sebagai kelas eksperimen dan X MIPA 4 sebagai kelas kontrol. Teknik pengambilan sampel dilakukan secara purposive sampling sehingga kelas sampel ditentukan oleh guru. Instrumen yang digunakan dalam penelitian berupa tes dalam bentuk pilihan ganda terdiri dari 20 butir soal dan 5 pilihan jawaban yang valid, reliabel dan daya pembeda soal serta indeks kesukaran dengan kriteria baik. Tingkat efektivitas e-modul dianalisis dari hasil uji n-gain. Hasil n-gain yang diperoleh pada kelas eksperimen 0,6 sedangkan pada kelas kontrol 0,5 namun keduanya dalam kategori sedang. Sehingga e-modul larutan elektrolit dan nonelektrolit berbasis guided discovery learning efektif terhadap hasil belajar dengan kriteria tinggi dan efektif digunakan untuk meningkatkan hasil belajar peserta didik. Implikasi penelitian ini dapat dimanfaatkan untuk mendapatkan pengalaman langsung bagi siswa.]]>

<![CDATA[The 2013 curriculum requires students to actively participate and be skilled within the use of knowledge and communication technology in the learning method so that learning is more interactive, efficient and effective. One of them is the use of e-modules or electronic teaching materials. This study aims to determine the validity, practicality, and effectiveness of the development of Guided Discovery Learning-based colloid system e-module for class XI grade senior high school students. This form of study is educational design research that makes use of the Plomp model. The validity check turned into completed with the aid of using five validators consisting of two chemistry lecturers at a university in the city of Padang and three chemistry teachers at a high school in Padang Pariaman district. The practicality and effectiveness test was conducted on three chemistry teachers and students of class XII MIPA at one of the high schools in Padang Pariaman district. The outcomes of validity and practicality had been analysed by the usage of the Aiken V formula and results of the effectiveness of e-module data using N-Gain formula. The conclusion of this research is that the e-module colloid system based on Guided Discovery Learning for class XI SMA which was developed is valid, practical, and effectively used to improve students understanding of concepts.]]>

<![CDATA[One effort that can be done to prepare SMA or MA students in entering the world of work is equipping them with the entrepreneurship skills, namely by integrating entrepreneurship into chemistry subjects through teaching materials in the form of modules. This study aims to reveal the level of validity and practicality of a CEP-oriented colloidal system module developed for class XI SMA or MA. The type of research used is Research and Development with 4-D model (define, design, develop, and disseminate). The research instrument used was a questionnaire in the form of validity and practicality sheet. This module was validated by 3 UNP chemistry lectures and 2 chemistry teachers of SMAN 12 Padang. Practicality test were conducted on 2 chemistry teachers and 30 eleventh grade students of SMAN 12 Padang. Data was analyzed by Cohen Kappa Formula. The results of the validity test showed that the module has a very high validity category (kappa = 0.86). Practicality test results by teachers and students showed that the module has very high practicality category (kappa = 0.82 and 0.83). Based on the results of this research, it can be concluded that the module developed was valid, practical.]]>

<![CDATA[Teaching materials are said to be practical if the practitioners or the experts state that the developed teaching materials can be applied in the research. The purpose of this research is to reveal the practicality of redox e-modules and GDL-based electrochemical cells for XII grade of high school students. This research is a continuation of educational design research with the Plomp development model at the prototyping stage, this research was conducted at SMAN 1 Lintau Buo Utara. The data were analyzed with the Aiken V formula. The results of one-to-one evaluation showed that the e-module uses clear fonts, covers and attractive designs, the language used is easy to understand, the presentation of coherent material, videos and animations can help students to understand the material. The results of the analysis on the average Aiken V formula obtained a V value of 0.88 at the small group stage and 0.86 at the high category field test stage. This data is evidenced by the ability of students to answer questions on the e-module by 90.5 percent with a very high category. Based on the data analysis, it is concluded that the e-module redox and electrochemical cells based on GDL are practically used in the learning process with a high practicality category.]]>

<![CDATA[This study aims to analyse the effectiveness of the chemical equilibrium module based on guided discovery learning on the learning outcomes of students. The study design uses a randomized control-group pretest-posttest design with quasi-experimental type. The population consisted of grade XI students of SMAN 1 Tigo Nagari in the 2019 till 2020 school year and samples were taken using simple random sampling technique. The research instrument was in the form of multiple choice tests, the data were analysed by n-gain test and hypothesis testing by t test. Based on the analysis of the data obtained n-gain experimental class is higher than the control class with a medium category and the hypothesis test obtained sig (2-tailed) less than 0,05. Analysis of these data concludes the hypothesis is accepted in other words the use of a chemical equilibrium module based on guided discovery learning is effective in improving student learning outcomes in class XI of SMAN 1 Tigo Nagari.]]>
