Keywords:
Open-Ended Problem, LKPD, developmentAbstract
This study aims to develop and analyze the feasibility, effectiveness, attractiveness and practicality of Open-Ended Problem-based Student Worksheets (LKPD) on the material of plane figures for seventh grade students of junior high school as teaching materials. This research is a development research using the ADDIE model which consists of 5 stages, namely analysis, design, development, implementation, and evaluation. LKPD validation was carried out by 3 expert lecturers who are competent in their fields. After being validated, LKPD was tested on seventh grade students of SMP Perintis 2 Bandar Lampung and the responses of students and educators after using the development product were observed through a questionnaire. The results of material validation obtained a value of 4.74 with the criteria of "valid", media validation obtained a value of 4.28 with the criteria of "valid" and language validation obtained a language value of 4.66 with the criteria of "valid". Student responses showed that the LKPD product was "interesting" with an average of 4.61 and "practical" according to educator responses with an average of 4.9. And the percentage of student posttest scores after using LKPD reached 83% which exceeded the minimum limit of classical completion in junior high school. Thus, it can be concluded that the LKPD based on Open-Ended Problems on the material of flat shapes for grade VII junior high school students that was developed is suitable for use as teaching materials.
