Abstract

This study aimed to examine the feasibility of a STEM-oriented RADEC learning design to build collaboration skills of Class XI high school students in determining the pH route from several natural indicators. The ability to collaborate is one of the important competencies of the 21st century so that teachers in the field must be able to develop these skills in students so that they can work together in groups. The method used is descriptive research. Participants in this study were several students of class XI IPA at SMAN 2 Ujungbatu. The feasibility test of the learning design consisted of an internal feasibility test by two expert lecturers, one senior teacher, and an external feasibility test for five students of class XI. The results showed that the learning design using the STEM-oriented RADEC Model was able to improve students^ collaboration skills in completing the given task. From this research it can be concluded that the STEM-oriented RADEC learning design can be used to build student collaboration skills.
