Development of guided inquiry experiment student worksheet on the topic of acid and base grade XI to comprehend the concepts of chemistry 1Departemen Pendidikan IPA, Universitas Pendidikan Indonesia, Jl. Dr.Setia Budhi No. 229, Bandung 40154, Indonesia Abstract Chemistry is an experimental science. The learning process in the Laboratory can help students to learn in understanding the chemical concepts, prove various concepts and doing simple research. Acid and Base is one of the topics of chemistry that require experiment in the learning process. The Types of student worksheet available has not yet guide students to to comprehend the concepts of chemistry. This research aims to generate guided inquiry experiment student worksheet on the topic acid and base grade XI to find the concepts of chemistry valid and practical. This development research using stages of 4-D model i.e define, design, develop, and disseminate. Instruments of data collection used is validation sheet and practicality questionnaire. The developed experiment student worksheet was validated by five expert and Practicality test by 26 students in grade XI. The data obtained were analyzed using Kappa Cohen Formula. The data obtained were analyzed by using Cohen Kappa Formula. The validity test of the developed experiment student worksheet is in high validity categories. The practicality test of students about developed experiment student worksheet indicated a very high category. While the teacher practicality about developed student worksheet obtain a very high practicality category.This finding also suggests that the developed experiment student worksheet can help students to learn find the concepts of chemistry. In conclusion, the worksheet can be used in chemistry learning process in laboratory (experiment acid and base). Keywords: Experiment Student Worksheet, Guided Inquiry, Acid - Base, 4-D Models Topic: Chemistry Education |
