The Influence of Problem Based Learning Model on Scientific Process Skill and Problem Solving Ability of Student

This study aims to determine the average influence of science process skills and problem solving
students using Problem Based Learning model and conventional learning, knowing whether the influence of
conceptual and procedural knowledge of students who are taught by the model of Problem Based Learning is
better than students who are taught by Conventional learning. This research is a quasi experimental research.
The research population is all students of class X SMA Negeri 1 Bangun Purba semester II academic year
2016/2017. The sample was taken by random class, consist of 2 classes totaling 68 people. Class X-3 as an
experimental class taught by Scientific Inquiry model assisted visual media consists of 37 students, class X-2 as
control class is taught with conventional learning consists of 31 students. The research instrument uses essay
test that is 10 problem of science process skill and 5 problem solving problem. The resulting data were analyzed
using t test. The result of the research shows that: the average of the improvement of physics science physics
process skill using Problem Based Learning model is in medium category and the average of the improvement
of science process skill of students using conventional learning is in low category whereas the average of
physics problem solving student use Problem Based Learning model is in the medium category and average
problem solving students who use conventional learning is in the category of being, the average increase in
students 'science process skills better than the students' science process skills using conventional learning while
the average increase in solving The problem of students using Problem Based Learning model of learning is
better than solving student problems using conventional learning.
