<![CDATA[There are important components in the learning process to support student success, one of which is by utilizing Student Worksheets (LKPD) which are developed or designed by the teacher himself. To prepare or develop LKPD, educators need an appropriate development model. The ADDIE model is able to develop teaching materials according to student needs. The stages of the ADDIE model start from Analyze, Design, Develop, Implement, and end with Evaluate. Each stage is equipped with revision activities before moving on to the next step. This research aims to develop student worksheets (LKPD) based on science process skills in science subjects that are valid and practical. The results of research based on the validity of learning media showed that material expert validation results obtained a score of 81% in the "very good" category. The validation results from media experts obtained a score of 77% in the "good" category. Based on the level of practicality of the learning media from the results of the teacher's responses, a score of 100% was obtained in the "very good" category. From the results of students' responses, they obtained a score of 91% in the "very good" category. And based on the results of the analysis of science process skills indicators, it obtained a score of 88% in the "very good" category. Based on these data, the student worksheets based on science process skills that have been developed are valid, practical, and suitable for use in science learning in class IV with material on the states of matter and their changes.]]>
