Abstract:
One of the important goal of education is helping students to learn and
increase their knowledge. Today's students need to learn a number of techniques that will
not only provide better learning opportunities, but will also help them make decisions, find
solutions to problems, and help learners become more self-directed. In this process,
teachers use a variety of resources, information, games, and digital technologies to give
essential knowledge for the needs of learners and increase their interest for learning.
During the learning period, students face various difficulties and refuse to accept new ideas
and information. Therefore, by teaching how to deal with problems, learners can assess
their own goals and find solutions to any problems they face. This article discusses the
challenges and examples of problem-based learning in the middle grades.

Originally, problem-based learning was used in medical field and business curricula.
But now different educational fields also apply to PBL in aside range of disciplines.
Problem-based learning (PBL) is a student-centered approach in which students learn about
a subject by working in small groups to solve a problem. This problem is what drives the
motivation and the learning. We need PBL because it is good way to think critically,
broaden way of thinking and self-esteem. The principal idea behind this is that the starting
point for learning should be a problem, a query, or a puzzle that the learner wishes to solve
(Davis & Harden, 1998; Harden & Davis, 1999). Learning goals are to be formulated by
consensus, and new information is to be learned by self-directed study, which ends with
group discussion and evaluation (Smits et al.,2002). According to Nilson (2010) " A well-
designed PBL project provides students with the opportunity to develop skills related to
working in teams, managing projects and holding leadership roles, oral and written
communication, self-awareness and evaluation of group processes, working independently,
critical thinking and analysis, explaining concepts, self-directed learning, applying course
content to real-world examples, researching and information literacy, problem solving
across disciplines. By the views of Nilson, it is clear that PBL method is beneficial for
students as it is mainly student-centered approach, encourages learners to enjoy and
understand better, as well as, it improves lifelong skills. Besides, this method is also useful
for teachers in order to grab student's attention, to urge learners to study more and do some
