The purpose of this study explains the effectiveness of the student activity sheet model to enhance scientific creativity and student learning outcomes and student responses to the learning process. The research design used pre-experimental with one group pretest-posttest design. The study's subject was the student activity sheet (SAS) model and the implementation of primary teacher Education undergraduate students who programed a science introductory concept course during the 2019.1 registration at Open University. Data collected using test methods and questionnaires with product cognitive test instruments, cognitive process tests, scientific creativity tests and student questionnaire responses. Data analyzed by t-test and the proportions calculated. Normality test and homogeneity test are done before the t-test is applied. Increased creativity and student learning outcomes are calculated using normalized N-Gain. The results showed: 1) Improvement of students' scientific creativity after joining learning in the medium category. 2) Improving student learning outcomes after participating in learning in the good category. 3) Student responses to the learning process in the positive category. Based on the above, it can be concluded that the application of student activity sheet model used in learning activities to improve scientific creativity competency and student learning outcomes is effective.

The purpose of this research was to improve student learning outcomes, activities, and positive responses. Classroom action research carried out in 4 stages: planning, action and observation, reflection, and revision that carried out in three cycles. Data were collected through test, observation, questionnaire, and documentation. The participants of this research are class XI-3 students of State Senior High School 1  Krembung. Data were analyzed descriptively quantitative. Observation cycle 1, motivation by the teacher, learning objectives, explanation of working on worksheets, worksheet systematics, class control, seating settings, and intelligence use are lacking. The mean obtained is 55 with grade completeness of 38%. Observation cycle 2, delivery of learning objectives hastily, connecting material with daily phenomena is less clear, concluding that the material is not systematic. However, many students begin to maximize their intelligence to obtain a mean 63.75 with class completeness of 60%. Observation cycle 3 shows an improvement, and the process runs smoothly so that the mean is 74 with grade completeness 81%. Students' positive activity increased from cycle I to cycle III while learning achievement from cycle one to cycle three increased respectively by 38%, 60%, and 81%. The student’s response questionnaire showed that students had a positive attitude with 81.73% and 18.27% negative. In conclusion, student achievement and activity in learning had increased and received a positive response.
