According to Nurhadi 2004:109, PBL is a learning model that uses real world problems as a context for students to learn
about how to think critically and problem solving skills as well as to acquire the knowledge and essential concept of the subject
matter. This is in accordance with the opinion of Hong 2007:4 who stated that in the PBL, the teacher gives the students problems
of the real world to students to be solved together. At the moment discuss and answer the problems, students should engage in real
activities such as observing, collecting data and analysing together with other students in a group or in the classroom.
For students studying at the school, students will be faced with problems to be solved and resolved. The students task is to
find a resolution to the experiences at the school designed by the teacher. After graduating from school, students will still be faced
with all kinds of issues that must be addressed, it is expected that the experience in school will help in the search for a settlement.
Further Nurhadi 2004:109 stated that the role of the teacher in problem based learning is presenting problems, ask
questions, facilitate research and dialogue. Problem-based instruction cannot be executed if the teacher does not develop a
classroom environment that allows the occurrence of exchange of
ideas openly. The bottom line, students are faced with a situation of an authentic and meaningful issue that can challenge students to
solve it. PBL directs students to have the desire to understand, learn good learning needs so that want to use, and seeking out the
best learning resources in the framework of solving the problem at hand.

learning facilities. In addition, teachers provide support that can promote the growth of students

environment that is open and guide the exchange of ideas. Based on some of the opinions above, it can be concluded
that Problem Based Learning Model is a model of learning which aims to make the learners actively discuss with the group in order
to solve the problem based on materials that have been taught.
