INTRODUCTION
1.1. Background
Teaching and learning process is the core of the educational process as a whole
the teacher become the primary role holder. Teaching and learning activities is a
series of activities between teachers and students as a basis of reciprocal relationships
that occurs in an educational situation to achieve educational goals. Learning process
is regard to the cognitive, affective, and psychomotor.
Learning often emphasize only to the cognitive aspects on remembering activity,
understanding activity, and applying activity. In future, the learning in the cognitive
aspects required and must develop problem solving ability. Include in the teaching
and learning of physics.
Basically students have skills or ability in learning, for example, questioning
skills, hypothesis, investigation, observation, classification, prediction, interpretation,
and communication. However, these skills are sometimes not appears to learn
problem solving ability that gave rise to these students. Therefore, to develop and
improve the skills or ability of the learners need a model of learning so that students
can be actively involved.
According to one of the International Study on student’s cognitive abilities are
TIMSS (Trends in Mathematics and Science Study) conducted by the IEA
(International Association for the Evaluation of Educational Achievement). TIMSS
201 results in physics field shows that the Indonesia gained 397 values, and this value
is below the international average is 500. The data indicates that the absorption of
students in physics learning. Based on the results of TIMSS, it can be said that the
students' ability of problem solving skill Indonesia is still low.
Results of interviews with physics teacher about student learning outcomes are
seen from daily test is still low and evidenced by average value in semester exams in
class X SMA Negeri 1 Panyabungan. Students in X just reached 64 score in final
too far from absolute score (KKM) 75 who students must reached. In addition,
students are not familiar to solve physics problems in divergent question.
Based on observations made by researchers and distributed to students in Senior
High School (SMA) Negeri 1 Panyabungan is still dominated by the conventional
learning. Teacher use conventional learning from beginning till end of learning
process, teacher just use question and answer, discussion tends to procedural and
more emphasis on learning outcomes, instead of the understanding of the concept.
From the data of learning physics is still relatively low about the cognitive. And also
obtained the students are have less interested with the physics subject. Most of the
students said that physics is a difficult subject to understand, boring, and most
formulas, concepts, theories also considered complicated. This is also evidenced by
the low activity of students in the learning process. Besides that, the questions that
presented by teachers and also the examples of which are given focused by the
formulas. Without explaining the detail concept beforehand, this causes student using
the wrong formula for completing the assignment from teachers, and if the problem is
different from the example given by teacher, the students will be confusion solve it.
It is also due to the learning model used is less varied. Teachers simply use the
conventional model, where the learning system centered on teachers, and more
actively and students only passively. The Student follow the direction of the teacher
and listen to what the teacher explained, and are not required to express an opinion,
discuss or investigate the knowledge that obtained so significantly less tedious and
experience saturation. In addition, the lack of ability of the students to connect the
concepts of physics are taught by teachers with daily life as causes less interest
students learn physics.
In achieving learning standard and to obtain a high learning outcomes include
problem solving skills are not only supported by facilities, learning models are also
influential. In the subject matter of physics, not all the learning model can be
implemented well, therefore the selection of learning model leads to successful
problem-based learning (PBL) courses, students work with classmates to solve
complex and authentic problems that help develop content knowledge as well as
problem-solving, reasoning, communication, and self-assessment skills (Stanford
University, 2001: 1).
Research of models with the type of problem based learning has been made by
Pinar Celik, et al (2011) about success in Physics course. The result showed that the
average score of students who give problem based model 78.85 and control class just
raised 61.45. Hasanul Hadi, et al research showed control class using conventional
learning and experiment class using problem based learning model. The result
showed that the average score of students who give problem based learning model
62.3 and control class just raised 56.
Based on the above explanation, so the student need a learning environment that
engages students actively or in other words emphasize the involvement of students in
the learning process so that the students are more understand and also understand the
material being taught and become more active. Because basically learning is a change in behavior that results from the learner’s interaction with the environment (Michael, 2003: 3) .In this case the process of the work done by a person to obtain a new
behavior change as a whole, as a result of experience by itself in interaction with the
environment. The researcher proposes problem based learning model to overcome or
to be solution to solve the matter. Problem based learning is one alternative that is
innovative learning with constructivism based.
However, the problem based learning model has weaknesses in its application.
Weaknesses of the problem based learning model, for example the conditions not
conducive to school, need tools and infrastructure that not all schools have them, and
require a long time. Based on the above description, the researchers will conduct
research under the title "The Effect of Problem Based Learning Model toward
From the explanation above, can be identified the scope of the problem, namely: 1. Students assume that physics is a lesson that still less interesting and
difficult to understand.
2. Less interest in learning that is focused on the formula, physics
learning process is teacher center, and rarely to conduct with
experiment.
3. Teacher respond to the student’s work just answer right and wrong
without the reason, and less of problem solving skill.
4. The using of a less varied learning models, as well still a low level of
understanding of the concepts.
1.3. Problem Limitation
Based on the identification, the researcher limit this problem, there are:
1. Learning model that use is problem based learning model.
2. Research conducted in two classes namely control class and
experiment class that implement of problem based learning model.
3. Subject matter that will be present is Dynamic Electricity.
4. The results of the study examined only cognitive aspect actually
