This project explores different types of problem-based learning (PBL) cases in science education, including investigative, decision, directed, interrupted, clicker, and intimate debate cases. It also incorporates labs, datasets, and simulations to enhance the learning experience.

Cases types • Investigative: focus on 3Ps: Problem Posing, Problem Probing and Peer Persuasion • Decision cases • Directed or Guided Cases • Interrupted Cases • Clicker Cases • Intimate Debates All can incorporate labs, datasets, simulations
Sankofa • At the School of Health Sciences and Research, the faculty, staff and students embarked year-long cultural awareness and fundraising campaign called the Sankofa project that culminated in a 10-day study abroad trip to Egypt for 44 students. Two HSR teachers developed a curriculum that sought to create an extracurricular experience program that will engage students in the retelling and reclaiming of authentic Egyptian history through educational seminars and assignments, field trips and fundraising activities. Arabic language training for HSR students was conducted by Emory undergraduate and graduate students..

Not a Tumor: Scene1 The Griswold family loved taking road trips, especially during spring break. This year, their destination was Washington, DC to see the historical sites and take in the beauty of the blooming cherry trees during the annual National Cherry Blossom Festival. As they strolled along the paths lined with trees in full bloom one beautiful morning, the youngest child of the family, Audrey, was running in between the trees and swinging around on their trunks. Suddenly, she came to a halt. “Look, guys! There are huge bumps on this tree!” “Heh, that tree has a tumor! Watch out, Audrey, you’ll catch it!” teased Rusty, Audrey’s brother. “Eh, you can’t catch tumors, Rusty. Weird, only a few trees over here have these bumps. A tree tumor...” murmured Mr. Griswold, as he pulled out his iPhone. “Is there really such a thing?” What could cause large growths, also known as crown galls, on trees? Provide at least two hypotheses that explain the formation of crown galls on trees
“Welcome to the 2010 Vancouver Winter Olympics!” read the sign over the entrance to the arena the figure skating competition was taking place. “Remind me why we are going to see women’s figure skating?” complained Sheldon. “Because, Penny wants to go.” Leonard explained, hastily adding, “You made us all go watch curling.” Before the competition could start, a huge blizzard arrived. TV crews, athletes, and the audience were all ready but the judges couldn’t be found! The blizzard had caught them unawares and they were stranded in their hotel, unable to drive through the roads now clogged with stopped and abandoned cars. “See, I told you this was a bad idea,” Sheldon said. “Now we have to wait for the silly judges. We’ll be here for days!” “Don’t exaggerate, you baby,” Leslie said. “Besides, I bet we could judge the competition. It’s just a bunch of spinning and jumping around and we all know rotational mechanics.” “Yeah, we would even be more objective since we could judge them based on their strength and how well they take advantage of the fact that they can change their moment of inertia,” Leonard replied.
What are educators’ concerns about implementing PBL in their courses? • Brainstorm in small groups for 5 minutes. • Report your top 3.
Barriers to PBL • Content coverage (breadth v. depth) • Prep time • Standardized testing • Difficult in large classes • Resources aren’t there • Loss of control, too many risks • Unclear assessment • Handling student resistance • How to facilitate and fairly assess group work
Challenges • Curriculum change • Preparing faculty to facilitate • Preparing students for PBL learning • Writing new PBL units • Adapting PBLs to local needs • Assessment • Facilities • Doing PBL in Large Classes
Challenges Preparing faculty Curriculum change Rewards, incentives Preparing future faculty Mentor buy-in Funding paradigm Preparing students for case learning & group work TIME Writing new cases Adapting cases to local curricula & students Assessments Facilities
Helping Faculty: Adapting Cases • Know your audience • What do students know? • What Interests them? • Know your curriculum • What concepts are hard to teach? • What concepts can you connect to real world issues? • Define your objectives • What do you want them to know and be able to do? • What “Learning Issues” do you want students to investigate?
The important thing in science is not so much to obtain new facts as to discover new ways of thinking about them.Sir William Bragg (1862 - 1942)and isn’t this true in all our disciplines?
What more can you ask? Results of meta-analysis 1200 studies: • Cooperative learning promotes higher individual knowledge • Retention was higher • Students enjoyed it more • Students develop better social skills • Students are more articulate • Students respect different perspectives • Johnson and Johnson 1989, 1993

Finding Cases • Your assignment • Find a case, a news story, or an existing PBL that might meet your objectives for student learning • We’ll talk about how to modify and adapt it • 15 minutes • Don’t obsess…doesn’t have to be a perfect fit
Adopt and Adapt • Using the Finding Cases handout, the examples files on the jump drive or the powerpoint, find at least one case that you might use to teach a difficult concept. • Report in 15 minutes • Why do you think it’s a good case? • How might it challenge and engage your students? • How would you modify the case or PBL to make it have a service learning or community research component?
