The Improvement of Students’ Ability in Formulaing and Testing Hipothese through Scientific Process Skill Approach with Practicum Method
in Grade XI MIPA 1 SMAN 1 Parung In the First Semsteron 2017/2018 School year
Formulating and testing hipotheses are ways to trainstudents to think scientifically and tahtto help them answering various phisical problem using scientific method. The research is aimed to improve the ability of the students in formulating and te sting hypothesis after implementing scientific process skillapproach with practicum method on material elasticity concept. The desain of the research was an action research satrted from planning, acting, observing, and reflecting. After a cycle was completed,the reasearcher made a reflective overview and followed by a following cycle with some improvement actions. The action research was conducted in three cysles. The subject of the research was the students in Grade XI MIPA 1 SMAN 1 Parung. The calss was choosen because it has the lowest ability in formulating and testing hypothesis. There were only five out of thirty five studentshas acvieved 70% ability in the skill. It means that only 16 % of the students passed the minimum kriteria. The aspect measured in the research is the ability of the students’ in formulating and testing hypothesis with 70% acvievement in passing the minimum criteria and 80%of the classical acviement. The average performance result form the three cycles were (1) 67,43; (2) 70,97; (3) 73,51;. After the test on formulating and testing hypothesis in the three consecutive cycles,the average score gained were 70%, 75%,and 83%. The result of the research shows that the scientific process approach with practicum method can improve the students’ ability in formulatign and testing hypithesis in understanding material elasticity concept.
