WAYS TO IMPROVE THE UNDERSTANDING ON PHYSICS CONCEPT THROUGH PROBLEM-BASED LEARNING COMBINED WITH GOOGLE CLASSROOM ON KINETIC GAS IN GRADE XI SCIENCE 5 CIBINONG 3 HIGHSCHOOL
The research was aimed in finding out the improvement of student’s understanding on the physics concept on kinestic gas in grade XI Science 5 Cibinong 3 Highschool in the first semester 2019/2020 School Year through Problem-Bsed Learning combined with Google Classroom. The hypothesis testing of the research was the application of problem-Based Learning combined with Google Classroom could improve the understanding on the physics concept on kinetic gas theory on the students in Grade XI Science 5 Cibinong 3 High School..
The classroom action research was conducted on November 2019 on 36 students in grade XI Science 5 of Cibinong 3 High School in two cycles. The data was collected through pre test and post test. The tests were kognitif test in the form of multiple choice test. The tests consists of three different level of kognitif aspect. The level were understanding (C2), applying (C3), and analyzing (C4) on every cycles. The students’ activities were also recorded in the form of observational check list to see the learning process using Problem-Based Learning combined with Google Classroom by the observer.
The result of the research showed that the application of Problem-Based Learning combined with Google Classroom could improve the learning achievement of the students from 74,86 in the first cycle to 82,45 in the second cycle. The data also showed the average of each level of kognitif in the test items also improve from the first cycle to the second cycle. The C2 level (understanding) improved from 79% to 86%. The C3 level (applying) improved from 60% to 81%. The C4 level (analyzing) improved from 68% to 78%. Therefore, it can be concluded that the use of Problem Based Learning combined with Google Classroom improve the understanding of the physics concept on kinetic gas og grade XI Science 5 Cibinong 3 High School.
