In problem-based learning classrooms, the roles and responsibilities
of both teachers and learners are different from
those in more traditional types of school-based learning.
Generally, in problem-based classrooms, the teacher acts as
a coach for or facilitator of activities that students carry out
themselves. The teacher does not simply present information
or directly control the progression of work. Instead,
the teacher provides students with appropriate problems
to work on, assists them in identifying and accessing the
materials and equipment necessary to solve the problems,
gives necessary feedback and support during the problemsolving
process, and evaluates students’ participation and
products, with the goal of helping them develop their
problem-solving as well as their language and literacy skills.
These activities are described below.
