Abstract

The material for hydrocarbons is quite dense but the allocation of study time at school is limited so that learning becomes less than optimal. Teaching materials are needed that can help students learn in class and independent learning outside of school. Technological developments allow teaching materials to be developed in electronic format. This teaching material can be used anywhere and anytime which is accessed via a mobile phone. In general, students already use Android, but it has not been widely used in learning. The teaching materials used in MAN 2 Kerinci are not yet scientific. Research was carried out with the aim of developing interactive e-modules through an android application based on guided discovery learning on hydrocarbon material for class XI SMA/MA and determining its validity and practicality. The type of research used is educational design research with a plomp development model. The instruments used in this study were validation and practicality questionnaires. The data obtained were then analyzed using the Aiken's V formula and the practicality percentage formula. Based on the research data, the validation test shows that the e-module is valid (0.83). The practicality test shows that the value of practicality for teachers and students is very practical (91% and 83%) in small groups.

Abstract

The COVID-19 pandemic has affected the education system in Indonesia, especially in the implementation of learning. Due to a lack of time, learning using a scientific approach does not go well. One way to overcome time constraints is to use discussion techniques in learning. Therefore, research is needed that aims to compare student learning outcomes using the Guided Inquiry and Discovery Learning learning models using the Buzz Group discussion technique on acid-base titration material. The research population was all students of class XI, IPA MAN 1, Kota Bukittinggi, consisting of 4 classes. The sample is determined by the random sampling technique. Class XI IPA 1, the experimental class, uses the guided inquiry model, and class XI IPA 2, the experimental class, uses the guided discovery model with the buzz group discussion technique. Posttest data collection was done in the form of essay questions, with a total of 65 questions. The results showed that there were differences in the average scores of the two experimental classes. Based on the results of hypothesis testing, it was concluded that learning using the guided inquiry and guided discovery models with the buzz group discussion technique differed significantly.
