1. Problem Based Learning

2. Advantage of Problem Based Learning
1. Development of Long-Term Knowledge Retention
reinforces understanding of subject matter
2. Use of Diverse Instruction Types
caters for similar learning preferences
3. Continuous Engagement
engages students by acting as a break from normal lessons and common exercises
4. Development of Transferable Skills
real world scenarios
5. Improvement of Teamwork and Interpersonal Skills
hinges on interaction and communication, hence builds team work and collaboration

3. Disadvantages of Problem Based Learning
1. Potentially Poorer Performance on Tests
Whereas problem-based learners develop skills related to collaboration and justifying their reasoning, many tests reward fact-based learning with multiple choice and short answer questions.
2. Student Unpreparedness
Participation may be hindered due to immaturity, unfamiliarity, lack of prerequisite knowledge
You can partially mitigate these issues by actively monitoring the classroom and distributing helpful resources, such as guiding questions and articles to read. 

4. 3. Teacher Unpreparedness
You may have to adjust teaching habits
You could concentrate on:
Giving hints to help fix improper reasoning
Questioning student logic and ideas in a constructive manner
Distributing content for research and to reinforce new concepts
Asking targeted questions to a group or the class, focusing their attention on a specific aspect of the problem

5. 4. Time-Consuming Assessment
Assessing a student’s performance throughout a problem-based learning exercise demands constant monitoring and note-taking.
Factors to take into account:
Completed tasks
The quality of those tasks
The group’s overall work and solution
Communication among team members
Anything you outlined on the activity’s rubric

6. 5. Varying Degrees of Relevancy and Applicability
It can be difficult to identify a tangible problem that students can solve with content they’re studying and skills they’re mastering
May divert from objectives

7. Steps to Designing Problem Based Learning
1. Identify an Applicable Real-Life Problem
2. Determine the Overarching Purpose of the Activity
3. Create and Distribute Helpful Material
4. Set Goals and Expectations for Your Students
5. Participate
6. Have Students Present Ideas and Findings
