Development of Guided Discovery-Based e-Module on Colligative Properties to Improve Higher Order Thinking Skills of High School Students
Abstract
Abstract The current condition of the Covid-19 pandemic is very influential on the learning process in schools so that a teaching material is needed that can increase the activity of students. This study aims to develop an e-module of colligative properties of solutions based on Guided Discovery Learning to improve Higher Order Thinking Skills (HOTS), as well as determine the level of validity, practicality and effectiveness of the developed e-module. This research and development uses the Plomp model which consists of 3 stages. The assessment instruments used are observation sheets, questionnaires, and learning outcomes tests. The e-Module was validated by six expert validators and tested on six students and 36 students at SMAN 14 Padang. The validity results of the e-module obtained an average value of Aiken's V of 0.84 with a very valid category. The results of e-module practicality by teachers and students obtained an average score of 0.90 and 0.88 with a very practical category. The results of the e-module learning effectiveness test obtained an average N-gain value of 0.691 with a moderate category

Abstrak Kondisi pandemi covid-19 saat ini sangat berpengaruh pada proses pembelajaran di sekolah sehingga dibutuhkan suatu bahan ajar yang dapat meningkatkan keaktifan peserta didik. Penelitian ini bertujuan untuk mengembangkan e-modul sifat koligatif larutan berbasis Guided Discovery Learning untuk meningkatkan Higher Order Thinking Skills (HOTS), serta menentukan tingkat kevalidan, kepraktisan dan keefektifan e-modul yang dikembangkan. Penelitian dan pengembangan ini menggunakan model Plomp yang terdiri dari 3 tahap. Instrumen penilaian yang digunakan yaitu lembar observasi, angket, dan tes hasil belajar. e-Modul divalidasi oleh enam orang validator ahli dan diujicobakan kepada enam orang peserta didik serta 36 orang peserta didik di SMAN 14 Padang. Hasil validitas e-modul diperoleh nilai rata-rata Aiken’s V sebesar 0.84 dengan kategori sangat valid. Hasil Praktikalitas e-modul oleh guru dan peserta didik diperoleh nilai rata-rata sebesar 0.90 dan 0,88 dengan kategori sangat praktis. Hasil uji efektifitas hasil belajar e-modul diperoleh nilai rata-rata N-gain sebesar 0,691 dengan kategori sedang.
Kata kunci: e-modul, guided discovery learning, higher order thinking skills, model pengembangan Plomp, sifat koligatif larutan.
