Kiprah Piawi. 2018. “Development of Student Worksheet based on Guided Inquiry with Class Activity and Laboratory in Thermochemistry Subject for XI Grade Senior High School”. Thesis. Chemistry Education. Postgraduated Program. Padang State University.
The study of development of student worksheet based on guided inquiry has been conducted for high school thermochemical materials. This study aims to determine the validity, practicality and effectiveness of student worksheet developed. The development model used is the plomp model. The results show that the developed student worksheet is very valid (82.1%). The application of guided inquiry in student worksheet has been practicality tested by teachers and students of 81.25% and 85.1%, respectively. This value indicates that student worksheet is very practical. Based on the activity aspect of students, the effectiveness of student worksheet based on guided inquiry reaches 84.4% (very effective), whereas based on learning outcomes have a n-gain value of 0.6 (medium). It can be concluded that the developed student worksheet is in very valid, very practical and very effective category so as to improve the understanding of students.
