CHAPTER I INTRODUCTION
1.1 Background
A great education is an education that can lift up the dignity and value of a State. Education established automatically can make a nation speak in the
international area. Learning activity is one of the most vital components in determining the quality of education. Learning activities performed by two actors,
are teachers and students. The behavior of the teachers is teaching and students are learning behavior. Teaching behavior and learning behavior is related to the
subject matter. Learning is essentially a process of interaction between teachers and students, either direct interaction such as face-to-face activities and indirectly,
by using a variety of instructional media Rusman, 2012. Teachers as classroom manager should be able to manage the classroom as a
learning environment that needs to be organized. As a manager, a teacher is responsible for maintaining the physical environment of the class to always fun to
learn and directing or guiding the processes of intellectual and social in its class. Thus the teacher not only allows students to learn, but also develop the ability to
work and learn effectively from among students. A teacher can actually improve adequate results in the learning process, where teachers as educators are able to
leverage the model and the right media in learning. In teaching, the teacher always requires students to learn, teachers also require students to solve problems, but
rarely teach how students should solve the problem Arends, 2009. On the other hand, Rusman, 2012 suggests that the curriculum Problem Based Leaning PBL
helped to boost the development of lifelong learning skills in a mindset that is open, reflective, critical, and active learning. PBL curriculum facilitates successful
problem solving, communication, teamwork and interpersonal skills better than other approaches .If we
view from the non-social factors include learning media, where learning media is one means of to enhance the teaching and learning
process. A great education is an education that can lift up the dignity and value of a State. Education established automatically can make a nation speak in the
international area. Learning activity is one of the most vital components in determining the quality of education. Learning activities performed by two actors,
are teachers and students. Learning activities performed by two actors, are teachers and students. The behavior of the teachers are teaching and students are
learning behavior Teaching behavior and learning behavior is related to the subject matter. Learning is essentially a process of interaction between teachers
and students, either direct interaction such as face-to-face activities The selection of media that will be used very concerned with teaching methods that will be
used. Therefore in teaching and learning activities teachers must have a strategy so that students can learn effectively and efficiently and are expected to hit the
goal. Based on data reported by the Department of Education of North Sumatra,
Friday 255, students in senior high school MA that pass the UN amounted to 119, 945 people 99.88 of the 120,090 participants. While the students who
pass the exam is 72,410 people 99.87 of 72,504 participants. For the IPA program, from 62,331 participants from the UN SMA MA in North Sumatra,
which pass as many as 62, 257 people or 99.88 percent. As for the national level graduation rate reached 99.70 percent of the 628,495 participants. Especially for
high school, there are eight regencies cities in North Sumatra with a 100 percent graduation. The eighth area of each Sibolga, as well as Pakpak Bharat, West Nias,
Dairi, Mandailing Natal, North Padang Lawas, Humbang Hasundutan and Nias.For the MA level, 100 percent graduation occurred in 24 of 33 districts
cities in North Sumatra. Nine districts were still some students do not pass the exam include Medan and Deli Serdang, Langkat, Labuhan Batu, Karo, South
Labuhan Batu, shavings, South Tapanuli, Asahan and North Padang Lawas. The researchers did the observations for approximately three months at SMA
Negeri 1 Berastagi, in the context of Field Experience Program PPL, researchers discovered a lot of various phenomena in the implementation of learning. In fact,
