ABSTRACT
The objectives of this research are: To know the effect of Problem Based Learning Model on student’s learning outcomes in the subject matter of Thermodynamics in Class XI SMA Negeri 2 Kisaran Academic Year 2014/2015.
The research method was quasi experimental. The populations were all XI IPA students in semester II that consist of 6 classes SMA Negeri 2 Kisaran. The samples of this research involves two class there are : XI IPA 3 become experiment class have 35 students and XI IPA 5 become control class have 35 students and define by random cluster sampling.
The results of research : Pre-test average value of experiment class was 39.42 and 39.54 for control class. Post-test average value of experiment class was 66.51 and 57.37 for control class. Standard deviation in pre-test are 10.89 in experiment class and 8.98 in control class and standard deviation in post-test for two class were 9.30 in experiment class and 8.05 in control class. The result of pre-test data using normality test from experiment class and control class was not normal and homogenous. Hypothesis criteria is: Ha is accepted if Zcount > Ztable and Ha is rejected if Zcount < Ztable obtained from list of Z distribution. After calculated data post-test by using non parametric analysis (spearman correlation) α = 0.05, value of Rs = 0.40, Zcount = 2.33, where Ztable = 1.96. if we compare to the correlation table, the effect of problem based learning model is effective. It shows that there was an effect problem based learning model for students learning outcomes in the subject matter of thermodynamics in class XI SMA Negeri 2 Kisaran.

1 CHAPTER I INTRODUCTION
1.1 Background
Physics is part of the natural science related by way of find out about
natural phenomenon that can be observed and can be measured systematically.
Physics is not only a mastery of knowledge in the form of a collection of facts,
concepts, or principles, but also the a process of discovery. Science learning
process is characterized by the emergence of the scientific method that
materialized through a series of scientific work, values and scientific attitude.
Based on the experience of researcher, Teaching experience program in
school at Senior high school during 3 months, learning process is done in the
classroom showed that students only receive information during learning activities
take place. Students just think that to learn it was only done in the classroom or
school. Researchers result from the number of students who giving less attention
and actively participate in learning activities. Students were bored, and less
interested in the subjects of physics and ultimately the acquisition of learning
achievement is not as expected. However, learning more emphasis on
mathematical calculation without a deep understanding of the concepts contained
in physics.
Although it has been the implementation of the new curriculum, student
achievement has not yet reached a maximum. Many students who have not be
able to achieve the competency standards set by the government. This occurs from
Several factors reviews such as students interest in learning. Based on the analysis
on student test results showed there are many students who received low score.
Therefore, we need a method or model of learning which is very appropriate to
enable students in the learning process.
Based on the analysis of the problems given in the replay, we known that
such questions are made to test the students cognitive abilities that include aspects
of the understanding and application of concepts. From these data, it can be
shown that the level of student achievement is still low. Teacher should strive
2
learners in understanding a concept. It is intended that the knowledge that a
student can mean minimal for himself.
Students choose to study physics with experiments. Students are easier to
understand and be able to clearly understand the concepts contained in physics.
Students can remember in a longer period of time when compared with the results
obtained from the lecture method. Furthermore, students are very difficult to work
on the problems of physics because they have to memorize formulas are very
much without knowing the meaning / concept of what is contained in physics.
Creativity of teachers that less encourages students to interested in the subjects of
physics, so that the results of the learning process is not as expected.
Teachers most influence on the learning process, because the teacher as
transmitter of material to students, should be able to convey the material to be
covered by appropriate methods and media and attractive. It will be impact on
student success in learning to follow and do the assignment of teachers.
According Chrispeels (2015) both of teachers and students valued working in
collaborative team. Collaborative learning refers to students working together
toward a common goal in small groups. Based on Dole and Bloom (2015)
identified five factors that play an important part in teachers decision to use
students centered pedagogy. Those factor are : (1) recognition acceptance of new
roles and responsibilities on the part of teachers and learners, (2) comfort level of
teachers and learners, (3) tolerance for ambiguity and flexibility, (4) confidence in
integrating technology and (5) integration of the new pedagogy within the larger
realities beyond the classroom.
There are three main requirements that must be owned by a teacher in
order to be a good teacher, as follow : (1) master teaching materials, (2) learning
skills, and (3) evaluation of learning. In the teachers mastery of learning skills
required to use a variety of instructional strategies. Appropriate learning strategies
and can attract the attention of students so as to create a fun learning environment
and can achieve the expected learning objectives.
The curriculum of 2013 have three learning models proposed, as follow:
Discovery Learning, Project Based Learning and Problem Based Learning and
3
learning as it is considered very appropriate to make the learning process.
Problem based learning model is one of the innovative learning model that can
provide active learning conditions for students. According Jin, Bridge, and
Botelho (2015) Problem Based Learning is scaffolded, indeed, through the
different strategies embedded process. Skinner, Mayer, and Winning (2015) said
that problem based learning have three stages, such as : stage 1: Importance of
Knowledge; stage 2: Gathering Information; stage 3: Exchanging Information.
Problem based learning an instructional model that involves students to solve an
instructional model that involves students to solve a problem through the stages
of scientific methods so that students can learn the knowledge related to these
problem and also have the skills to solve problems.
According to research result Sakai, D’eon, Trinders (2015) using problem based learning model, comparison of scores on the modified essay question
(MEQ) examinations were conducted separately for first and second year
students. Statistically significant difference among the three group of tutors was
found (F(2.611) = 1.70). statistically significant difference with a effect size,
where faculty performed on average 1.7% point better on the MEQ than senior
students under supervision. Makin research result (2015) which also applying
problem based learning model from 142 responses for this equestion, 35.2%
(n=50) of reqcruit recommending more PBL elements,26.8% (n=38) recommended more paramilitary training. It’s mean that problem based learning more effect than another model.
The problem previous research at the above is need a long time to carry
out experiments and sometimes overwhelmed teachers in implementing coach
against the group in turn.Based on the description above, the results of research
conducted, researcher is interested in doing research with different materials, a
study, research lesson plan shape don’t have problems to be solved by the students
so that researchers try to cover up the shortcomings of previous research that
objective to improve the learning outcomes of students with physics lifting the

2. Teachers didn’t have idea to create learning process so that students are
less interested to learning
3. The learning model used has been not effective for teaching proccess
4. Teacher not making students more interesting to think about find out the
concept of physics in our life
5. Teacher response to the student's work just answer right and wrong
without giving a reasons
6. Teacher not using media in learning proccess
