Abstract:
"This research aims to develop a teaching material in the form of a Student Activity Sheet (LKPD) Integrated Science, Technology, Engineering, and Mathematics-Project Based Learning (STEAM-PjBL) on the material of Electrochemical Cells and is used to determine the validity level of the LKPD in terms of content and construct validity and the practicality of the developed LKPD. This research is a Research and Development (R&D) development study using the 4-D model. In this 4-D model, there are four stages, namely the define stage, the design stage, the develop stage, and the disseminate stage. However, this research was carried out until the Develop stage because the disseminate stage was not carried out due to time constraints. This research uses instruments in the form of a validity content and construct questionnaire, a teacher and student response questionnaire. The LKPD was validated by five validators, including chemistry lecturers at FMIPA UNP and chemistry teachers at SMAN 6 Padang in the 2021/2022 academic year. The validation data obtained were analyzed using Aiken's v scale, while the practicality data were analyzed using a comparison of students' scores with the maximum student score. Based on the analyzed validation questionnaire, it can be concluded that the developed LKPD is valid with a value of 0.915 in the valid category. Meanwhile, the practicality of teachers and students obtained a score of 94% and 89% respectively, with a very practical category.".
