This study aims to develop: Student Worksheets (LKPD) integrated with problem-based learning model with TaRL approach to improve student learning outcomes.The study was conducted at SDN 28 Mendo Barat in grade IV. This study is adevelopment research (Research and Development) with a 4D model, namely thedefinition, design, development, and dissemination stages. The object of the studyis LKPD integrated with problem-based learning model with TaRL approach toimprove student learning outcomes. The instruments used were a feasibility testquestionnaire and student response questionnaire and teacher interview guide. Thefeasibility test was conducted by 6 validators, namely 2 material experts, 2 languageexperts and 2 presentation experts. User response tests were conducted on 20grade IV students and 1 class teacher in the trial class.

The results of theLKPD feasibility test by the validator reviewed from the aspects of material,language, and display presentation, the feasibility of the material obtained 0.80(feasible criteria), the results of the language feasibility of 0.70 (feasible criteria) andthe results of the display feasibility of 0.80 (very feasible criteria). The results of theLKPD field test by conducting a post test and pre test with the results of the gaintest showed 20 students with a high criterion gain count of 4 students with apercentage of 20% then 14 students with a medium criterion of 70% then 2 studentswith a low criterion of 10%. In other words, the student worksheets (LKPD) used arebeneficial and effective as learning media to improve student learning outcomes.
