The 2013 curriculum learning process includes three domains, namely affective (attitude), cognitive (knowledge), and psychomotor (skills). This study aims to develop a valid, practical, and effective Student Worksheet. The research method used is the Tessmer design, which consists of (1) Expert review; (2) one-to-one; (3) small group. Validation subjects were three experts, individual subjects were three students in class X in high school and small group test subjects were six students in class X in high school. The results showed that: (1) the validity of LKPD based on expert testing had a valid category with an overall average of 3.59; (2) the practicality of the contents of LKPD has a good category with an overall average of 3.70 and the practicality of the LKPD's expectations based on the responses of students has a very good category with an overall average of 88.70%; and (3) the effectiveness of LKPD based on the assessment of students' critical thinking skills in working on LKPD has both categories (including interpretation) and very good categories (includes analysis, evaluation, inference, explanation, and self-regulation).
