Conditions of mathematics learning is still less emphasis on the mastery of concepts for students. Classes are still dominated by the teacher as the main source of knowledge so the students get less chance to be active in learning process. It makes mathematics learning is not meaningful for students. Indonesian Realistic Education (PMRI) is a learning approach that links the student’s daily life of students with the concepts of mathematics for meaningful mathematics learning and easily understood by the students. To support the implementation of the learning with PMRI approach is required PMRI learning tools such as student’s worksheet. Student’s worksheet with PMRI approach still not well developed in many schools. One of the topics that could be taught by PMRI approach is rectangle and square. Therefore, researcher conducted a study with the aim to describe and generate worksheets that both approaches PMRI on the materials of rectangle and square. A good student’s worksheet is a student’s worksheet that satisfies of criteria such
as valid, practical and effective.
This research is a developmental research using Plomp development model, without the implementation phase. The trial was conducted on 36 student’s of VII-D SMP Negeri 1 Wonoayu. In this study, data obtained from the results of the validation, the result of learning implementation, the results of student’s score as learning outcomes and student’s respond.
From the results and discussion on this research can be concluded that the developed student’s worksheet satisfies aspect of validity (with an average total validity of 3.64), practically (LKS easy to use and with an average total learning observations of 3.81), and effectiveness ( student’s learning outcomes is classically passed out with precentage of 86.11% and the students gave positive responses to the student’s worksheet for more than 50% of each statement included in the category of strong or very strong).Therefore developed student’s worksheet in the category of good.
Key word: Student’s worksheet, PMRI approach, rectangle and square.
