Development of guided discovery learning based module on colloidal system topic for senior high school

This research aims to develop and reveal the validity category of salt hydrolysis module based on guided discovery learning. The type of this research is a Research and Development (R and D). This research used Plomp model which consists of preliminary research, prototype, and assessment phases stage. This research is limited to the prototype stage that is prototype II. This module was validated by three lecturers from Chemistry Department FMIPA UNP and two chemistry teachers from SMAN 1 2X11 Kayutanam. The results of the validity test showed that the eligibility of module content has a category valid (V=0.87), linguistic component has a validity category moderate (V=0.8), serving component has a category valid (V=0.89), and graphic component has a category valid (V=0.85). It can be concluded that the module developed has a category valid with average V of 0.85.

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.

“…Hasil penelitian tentang modul berbasis guided discovery learning telah banyak dilakukan oleh peneliti. Diantaranya, modul berbasis guided discovery learning memiliki kategori validitas dan praktikalitas yang sangat tinggi, seperti modul reaksi redoks dan sel elektrokimia [15] , modul stoikiometri [16] , modul minyak bumi [17] , dan modul sistem koloid [18] . Selain itu, pembelajaran dengan menggunakan modul guided discovery learning dirancang untuk motivasi belajar, pembinaan karakter, meningkatkan minat baca, dan mengembangkan kemampuan pengetahuan meta kognitif peserta didik [19] .…”

The development and determination of module validity aims to examine the application of guided discovery learning model to the material reaction rate. The development was carried out using the plomp model with 3 stages, namely preliminary research, prototyping stage and assessment. The stages carried out are only up to the prototyping stage and formative evaluation until the expert review stage. Expert review is carried out through an assessment of 5 validators, namely 3 chemistry lectures and 2 chemistry teachers. Data were collected using a validity questionnaire which was then analysed the Aiken V formula. Based on the results, the resulting module has a valid category with a V value of 0,83 but its practicality has not been tested.
