The Student Worksheets (LKPD) available so far only contain black and white writing. In addition, the pictures and questions presented did not attract students' interest in learning. Therefore, it is necessary to develop LKPD that can attract students' learning interests. This study aims to develop Electronic LKPD (E-LKPD) thematic learning based on Higher Order Thinking Skills (HOTS). This research is a type of development research (RnD). The development model uses the ADDIE model which consists of the Analysis, Design, Development, Implementation, Evaluation stages. The E-LKPD product that has been developed is then tested on validators, teachers, and students to determine the effectiveness of its use. Data analysis techniques were carried out descriptively, qualitatively, and quantitatively. Validation is carried out by three validators, namely content, material, and language validators. The research instrument is a teacher response questionnaire for practicality and a student response questionnaire for attractiveness. The average validation result of media experts is 3.6 with the "very valid" category, while the material expert is 3.83 with the "very valid" category and the linguist is 2.83 in the "valid" category with revisions. The results of the analysis of the practicality of the E-LKPD can be assessed from the results of the teacher's questionnaire score obtained a score of 3.43 in the "very practical" category while the results of the analysis of the attractiveness of the E-LKPD obtained from the results of the student questionnaire score with a score of 3.19 in the "good" category. Based on the trial, it was concluded that the results of developing the E-LKPD product for HOTS-based thematic learning were valid, practical, and interesting to use in learning in grade IV elementary schools.
