2Problem-Based Learning Basics
- Problem-based learning (PBL) is an instructional
approach that recognizes two educational outcomes
as critical to the development of effective
problem solvers. - 1st Outcome Acquisition of new knowledge and
skills. - 2nd Outcome High quality use of knowledge and
skills to solve problems. - The ability to develop new knowledge and use it
effectively when faced with real-world problems
is what distinguishes expert problem-solvers from
novice ones.
3What is problem-based learning?
- Problem is ill-defined, which prompts students
to ask questions about what is known, what needs
to be known and how to find out - Activities are student-centered
- Teacher acts as facilitator or guide
- Focuses on a real world problem
- Designed to target learning standards
- Challenges students to collaborate
- Allows students to develop problem-solving,
research, and communication skills
4PBL Concerns
- PBL units take too much class time.
- PBL strategies can be incorporated into a single
lesson or applied for an entire unit. - Units can vary in length from a few class periods
to two weeks. - PBL units are hard to develop or take too much
time to plan. - Search Internet resources for ideas.
- Start small and build on your efforts until you
feel comfortable enough to create an entire unit. - Students cannot learn the required material on
their own. - By designing the individual activities and group
lessons, you can make sure students explore the
topics required to master the needed concepts. - By using ongoing assessment throughout the
project, you can make sure groups are making
progress and meeting your expectations. - Students dont work well independently or in
groups. - Students are usually motivated to learn in PBL
settings, especially when they are able to use
their strengths and work as a team.
5Pumpkin Problem
Example Lesson
Problem The Pumpkin Company has a large batch
of pumpkin fudge that needs to be shipped to St.
Louis, MO, for a fall festival in October. What
is the best way to ship the fudge to keep costs
at a minimum and ensure that the fudge arrives in
perfect condition?
Student Activities Student Worksheet Students
complete a worksheet exploring the relationship
between speed, distance, and time as well as
mileage. Problem-Solving Students use Internet
resources to research the problem and develop a
solution that addresses issues related to cost
and time of year.
Idea from Brooke Merker, Morton
6Example Unit
Problem Statement The local board of the US Fish
and Wildlife Service wants to increase the
biodiversity of the butterfly populations within
Chautauqua Wildlife Refuge. Your task, as refuge
biologist, is to recommend a strategy to increase
the diversity of the butterfly populations at
this site.

7Student Activities
Scientific Investigations Students work
together to develop a survey method that will
ensure reliable, accurate data.

9PBL Unit Tips
- Develop your problem statement.
- Collaborate with a local business or organization
to find real-world problems. - Find a fellow teacher to work with as you develop
and implement the unit. - Keep it simple to challenge the students to set
the parameters of the project. - Choose your learning standards for the unit and
then outline the lessons and activities you want
to incorporate. - Develop lessons that will provide students
opportunities to explore the concepts needed to
target your learning standards. - Keep the activities focused on the students
rather than the instructor. - Develop your assessments.
- Create ongoing assessments quick quizzes,
checklists, etc. that will allow you to monitor
student progress throughout the unit. - Develop your final assessment and/or rubric to
outline the points an acceptable project should
include.
