APPLICATION OF PROJECT BASED LEARNING MODEL TO IMPROVE SCIENCE PROCESS SKILLS AND UNDERSTANDING CONCEPT OF FLUID STUDENTS GRADE X MIPA 2 SMA NEGERI 1 KALASAN

The research purposes are (1) to describe step learning fluid with project based learning which can improve science process skills and understanding physics conceptual (2) to describe science process skills with project based learning model on fluid matter (3) to describe conceptual with application project based learning model on fluid matter. The research design was a classroom action research (CAR), which were analyzed descriptively. Research subjects were students grade X MIA 2 SMA N 1 Kalasan, followed by 26 students, consist of 18 girls students and 8 man students. Actions taken in application of project based learning model type which consists of six phases, i.e. :(1) essential question; (2) design a plan; (3) creating schedule; (4) monitor the progress; (5) assess the outcomes; (6) evaluate the experiment/experience. Result of this research indicate that project based learning model to improve science process skill and understanding conceptual is conducted clearly. There is improvement science process skill which is shown six aspect observed include kind of categories and 1 aspect improve to very kind. Improvemet of understanding concept is shown 84,62 % student reached minimal achievement categories ≥ 75 with mean value of posttest is 80,2. In addition, an improvement in N-gain score of 0.42 is considered moderate. Improvement very positive response given by students with the application of project based learning model, can be seen from as much 65 % of the students gave the reponse was very positive and the other 35 % gave a positive response. Beside that, teacher gave the response was very positive to project based learning model and continue benefit research implementation of curriculum 2013
