Discussion question option 1: ◦ When considering implementing a Problem-Based
Learning curriculum in your own teaching environment: (a) What do you foresee as possible conflicts in adapting
your teaching style? (b) What considerations must you make for diverse learning
styles of your students?
Discussion question option 2:◦ Which classroom environment is PBL more
inclusive for facilitation of this type of learning: (a) K-3, 4-8, 9-12, College, and why? Give some examples.
“PBL expects students to collectively experience contextualized, relevant, ill structured problems and to strive to find and create meaningful solutions.” (Igo, 2008).
Students are presented with an authentic problem.
“The idea is to use the problem to introduce the concepts and problem solving skills necessary to solve the problem.” (Massa, 2008).
Developed originally at McMaster University. Has grown and been adapted by many
educators and professionals since the 1970s.
Can be a messy situation◦ Should not be easy or clear-cut
Can be confusing to a degree to provoke curiosity by students
Parameters may be blurry and expand or shrink over-time
Is intended to have multiple possible solutions Does not require a “correct” answer Is not stagnant or uniform
◦ Should be malleable over the course of investigation
◦ May lead to cross-curricular learning
Problem analysis◦ Students have an authentic problem presented to them◦ In groups they frame and analyze the problem
Determine what they know, need to know, outline the situation, and develop probable outcomes
Self-directed learning◦ Students need to work to find the information needed as indicated in the
analysis◦ Set learning goals◦ Determine resources needed to solve the problem◦ Split up the tasks amongst themselves
Brainstorming ◦ Students share new knowledge with group◦ Listen to each other to determine own level of learning
Solution testing◦ Determine a tentative solution◦ Determine if the possible solution satisfies the desired outcomes◦ If it satisfies desired outcomes, it is presented to peers to validate the
solution◦ If it is not validated, the above steps are repeated
This flow chart illustrates the process or stages of a PBL lesson from start to finish.
Note the ill structure and unclear path

Increased student involvement Deeper meaning and understanding gained by
students Incorporates all learning styles: audio, visual and
hands on. Uses a step-by-step process that deals with the
discovery facts not emotions. Working a real-time problem within a group as you
would in workforce. Enables you to learn and work out the complexities
of group dynamics in a safe setting. Scenarios do have a solution. Group receives one grade for the group.
Frustration by students because of ill structure nature of problem
Requires teacher to adapt and facilitate to a very high degree Problems within the group quickly come to a head due to time
constraints. Students may not have sufficient expertise to provide a viable
solution. Scenarios may not provide enough background information to
identify the real problems. Facilitator may not have a sufficient expertise to deal with the
scenario Facilitator may not have sufficient expertise to be able to deal
with problems that arise within group dynamics. Only one grade received, some group members may work
harder than others but still receive the same grade.
Teacher as coach◦ Teacher facilitates learning by:
Monitoring the learning process rather than direct instruction
Pointing students in the correct direction of resources and skills to facilitate solution seeking
Asking questions to keep the process moving and students interested
Effective Questioning Techniques http://www.phy.ilstu.edu/pte/311content/questioning/techniques.html Dealing with the dynamics involved with group work so
the process does not bog down Student as active problem-solver
◦ Students are active in every phase of identifying and solving the problem
Task: Teacher has a city designed and built by students ◦ The students may not know what the final outcome is, only they need to build a
city. ◦ The inquiry is very open allowing the students to discover aspects that may not
have been apparent. ◦ Teacher introduces various scenarios/problems to students throughout the
semester. Each scenario deals with a different aspect of the city. Example: Having a sewage system.
Students identify the facts about sewage systems; brainstorm ideas about what the problem really is and what they think about the situation.
This may lead to: How various systems work, alternative sewage systems, environmental issues, the role that soil plays in waste disposal, the impact on the water supply, waste disposal legislation, debates about the pros and cons of public/private operations, water contamination and/or purification etc.
The next scenario/problem may take them in-depth into different aspects of water purification systems, building on the knowledge they gained in the previous scenario/problem.
◦ At the end of the semester, the city is built, and in-depth research has been done on each piece of the city’s infrastructure. (Cox-Peterson, A., Shuler, C., Thompson, P., Wang, H., 1998).
Remember hands-on materials are important in PBL lessons:◦ Hands-on materials are powerful tools to learn concepts
and to test hypotheses in order to refine ideas ◦ A scenario/problem that has a learning need about why a
seed won’t grow could utilize a kit to test soil samples, or water samples, or a weather study could result.
◦ Anticipate what may be needed so that materials are on hand.
◦ Think artistically: field sketching, clay, botanical drawing, dance, plays, robot building, etc
(Cox-Peterson, A., et al, 1998)
