S tudents have difficulty in understanding Ec onometrics. Based on existing problems, needed a learning materials in the form of Worksheets based on Prac tice which is capable of supporting courses of Econometrics as well as being able to cultivate self-reliance in students. The purpose of this study is to describe (1) development of student activity sheets on teaching Econometrics, (2) the feasibility of the development of student ac tivity sheets based on teaching Econometrics, (3) student learning outcomes after using S tudent worksheets based on practical Ec onometrics, and (4) the response of the students of S tudent-based teac hing worksheets Econometrics. This research uses a type of research development by using 4 d approach (Four-D models). The products of this ac tivity are embodied in materials in the form of worksheets students prac tical work-based, where in eac h of the basic skills that exist within the c ourses of Econometrics will be served content material, Prac tic al tutorial with the help data processing software, as well as Prac tical c ase studies. Based on the review and validation of content and media expert expe rt each obtained a score of 31% and 35% with the criteria. Thus the student activity sheet-based prac tical feasibility in the process of teaching and learning ac tivities.
