Journal Title: International Journal of Advanced Research (IJAR) - Year 2018, Vol 6, Issue 4
Abstract
This research aims to identify the effectiveness of STEM-based Science Student Worksheet in improving multiple representation abilities of junior high school students. This research is expected to be the basis to find out more about the success rate of students through the use of STEM-based Science Student Worksheet. This research was conducted at SMPN 1 Rowokangkung, Lumajang Regency, precisely on 10, 12, 14 and 16 March 2018 in class VIIIC which amounted to 23 students, in Even Semester of Lesson Year 2017/2018. The design of this study is a pre-experimental one-pretest-posttest design. The result of the research shows that based on the average value of each cycle, there is improvement found in student multiple representation capabilities after using STEM-based Science Student Worksheet. It is characterized by the average of the post-test score that is better than the average of pre-test score. The increasing multiple representation abilities can also be seen from the N-gain value in each cycle which belongs to the high category with the value of N-gain of the 1st cycle is 0.702, the 2nd cycle is 0.747, the 3rd cycle is 0.700, and the 4th cycle is 0.707. Based on the research, it can be concluded that STEM-based Science Student Worksheet is effective to improve multiple representation abilities of junior high school students.
