ABSTRACT
This study aims to produce a student worksheet (LKPD) based on scientific literacy on ecology topic, to determine the feasibility of the LKPD as learning materials according to expert validators, teachers, and student responses, and its effectiveness in improving student's higher order thinking skills (HOTS). The research development is 4D Thiagarajan model. Product validation is done by content, learning strategy and media validators and also biology teacher assessment and student responses. The effectiveness test of worksheet was carried out at SMA Methodist An Pancurbatu at the X IPA 2 as the experimental class and at the X IPA 1 as the control class. The data were collected by using observation, interviews and student achievement test. The questionnaire instrument used Likert scale. Research result showed that the worksheet feasibility according to content (material), learning strategy and media experts were 92.19%, 92.2% and 94.8%, respectively, with very good category. Teacher's assessment and student responses were 93.24 % and 94.00% also with very good category. Meanwhile, the effectiveness test result showed that the gain score was 0.7 > g > 0.3 means that developed scientific literacy LKPD was effective in increasing of students' HOTS. The independent sample t-test result showed that there was a very significant differences of learning outcome between the experimental and the control classes (t count= 5.89; P=0.00). In this case, the learning outcome (HOTS) of the students who have used the developed worksheet in the learning process was significantly higher compared to the students who didn’t use the developed worksheet. The developed worksheet was effective to improve the student HOT, especially in answering the analytic (C4) and synthetic questions.
