The subjects of this study were students of class VIII D MTs Negeri 2 Bandar Lampung in the 2015/2016 academic period. Research data were obtained through mathematical communication tests and self-efficacy scales. The effectiveness test was conducted to determine the effect of Student Worksheets on mathematical communication skills and attitude analysis was carried out to determine the tendency of students' self-efficacy. The results of the preliminary study indicate the need to develop a Student Worksheets problem-based. Preparation of Student Worksheets begins by preparing a Student Worksheets and all its components based on the Student Worksheets preparation guidelines.
