<![CDATA[Student worksheet (LKPD) is a teaching materials containing activities that guide students in understanding topic. However, several studies have shown that LKPD is simply practice questions and are not tailored to students' needs. This study aims to design and test the effectiveness of a student-based LKPD.discovery learning assisted by wayground in improving mathematical connection skills and learning independence of junior high school students. This research is a Research and Development (R&D) with the Borg & Gall model, which consists of preliminary studies, planning and drafting products, expert validation, limited trials, extensive trials and product tests. The subjects of the study were 10 students of class IXA for limited tests and 32 students of class IXB for extensive tests and the subjects of product tests were 32 students of class VIIID for the experimental class and 32 students of class VIIIE for the control class in one of the public junior high schools in Bandung Regency. The research instruments include: Mathematical Connection Test, Learning Independence Scale, LKPD Validation Scale and Learning Assessment Response Scale. The results of the study show feasibility with several criteria: Validity obtained from the results of validation by material experts is 89% and media experts 90%, both in the very valid category. Practicality of 83% obtained from the results of student responses is in the very practical category and Effectiveness is obtained from the results of the Ngain analysis 60%, is in the effective category. Thus, LKPD based on discovery learning assisted by wayground effectively improves students' mathematical connection skills and learning independence.]]>
