Electronic Student Worksheets (LKPD) is innovative learning tools to make it easier for students in the learning process. This study aims to describe the practicality and effectiveness of electronic LKPD expectations on the concept of Biodiversity. The research method used Tessmer's Formative Evaluation design, through stages 1) expert review; 2) one-to-one evaluation; and 3) small group evaluation. The validator was 3 experts, the individual test subjects were 3 high school class X students and the small group test subjects were 4 high school class X students. Data obtained from the research instrument in the form of an assessmet sheet of practicality and effectiveness of expectations. The results of the research on the practicality of expectations have a very good category based on the responses of students and the effectiveness of expectations has a very good category (including interpretation, analysis, evaluation, inference, and explanation skills) and a good category (including self-regulation skills) based on the assessment of students' critical thinking skills.
