Four children work together on a robotics project at a table. One child reads a book, another types on a laptop, a third adjusts a friendly-looking robot, and the fourth smiles while using another computer. A cardboard box sits under the table. The scene shows teamwork, curiosity, and creativity in STEM learning.

Do you remember doing projects when you were a student? My teachers typically assigned everyone a standard project; we completed them and turned them in and then received a grade. It wasn’t very rigorous, creative, or engaging. Today, many teachers turn to project-based learning and problem-based learning. Let’s look at how they compare.

A comparison chart shows the differences between Project-Based Learning and Problem-Based Learning.  Project-Based Learning: Focuses on student involvement, with teachers preparing before the project and offering support as needed. It connects to students’ lives or future lives, uses teacher-developed driving questions, and is open-ended—students make choices that shape the project’s outcome and research path.  Problem-Based Learning: Focuses on student inquiry, with students developing the driving questions. It is also open-ended and student-directed, with teachers acting mainly as guides and offering support when necessary.  The chart is adapted from a blog entry by Terry Heick at teachthought.com.

It’s one thing to describe the difference between the two, but another to look at actual samples.  Let’s look at project-based learning and problem-based learning samples from English language arts, social studies, math, and science. 

A comparison chart titled Middle/High School English Language Arts shows examples of Project-Based Learning and Problem-Based Learning activities.  Project-Based Learning: Students connect a class novel’s theme about a protagonist trying to civilize a remote Amazon tribe to real-world research on uncontacted tribes. They investigate questions like whether such tribes still exist, where they are, and whether they should remain isolated. Students then create a presentation or mini-lesson explaining ethical dilemmas in Brazil, Venezuela, and Colombia, justify or critique government decisions, and include visuals and creative elements.  Problem-Based Learning: Students consider a class novel where the protagonist’s school is dysfunctional and comments that “school atmosphere is everything.” They identify a personal or school-related issue to research, create a research plan, gather evidence, and present findings in any format. Presentations should include background information, analysis of the issue, key evidence, and a conclusion that answers their research question.A comparison chart titled Elementary Social Studies shows examples of Project-Based Learning and Problem-Based Learning activities.  Project-Based Learning: Students build on lessons about archaeologists and how they study bones and artifacts to learn about human history. They research different types of work archaeologists do and choose another related field to explore. Students teach the class about their findings, explaining where the work happens, what it involves, and how discoveries impact our understanding of the past. The class then debates which archaeological projects or goals are most important for understanding history.  Problem-Based Learning: Students are told that “the city is in danger” because the mayor has moved away and everything has shut down. Working in small groups, they research and design a plan to rebuild and organize the city. They justify their proposals with evidence and reasoning, creating a persuasive visual presentation using tools such as chart paper, posters, PowerPoint, or maps to explain their ideas for restoring the community.A comparison chart titled Upper Elementary/Middle School Math shows examples of Project-Based Learning and Problem-Based Learning activities.  Project-Based Learning: Students apply their knowledge of area and perimeter to design the layout of the perfect theme park. The teacher may provide specific design requirements or measurements for students to follow.  Problem-Based Learning: Students identify a real-world issue that can be addressed using geometry. For example, if the school’s main offices are being renovated, students must plan how to relocate them elsewhere in the building. They design a new layout that fits all existing furniture, justify how it solves the problem, and list additional considerations, applying geometric reasoning to create an efficient solution.A comparison chart titled Middle/High School Science shows examples of Project-Based Learning and Problem-Based Learning activities.  Project-Based Learning: In a scenario called “Don’t Trash the Earth,” students respond to a community issue where the local landfill is running out of space. Acting as consultants, they evaluate recycling and waste-management practices in their school and community. After researching past and current methods, teams develop a new recycling plan with cost analysis and supporting data. They present recommendations to a committee, using brochures to inform and persuade the public to take action.  Problem-Based Learning: Students choose a science-related issue, such as a proposal to build a new landfill near the school. They research the topic to understand all aspects, discuss different perspectives, and identify real-world impacts or consequences. Finally, they create a public relations plan tailored to different audiences to advocate for their position on the issue.  The chart cites the source: ronaldreaganms.pwcs.edu

A Final Note

As you reviewed the samples above, what did you notice? The main difference is the amount of student ownership and self-direction. With problem-based learning, you’ll want to dictate less of the specifics of the task. Both project-based and problem-based learning engage students at high levels; simply choose the option that best suits the learning needs of your classroom.
