PBL Resource Site – How to Plan, Manage and Evaluate

pbl stem

This week I led a four-hour training session – “Project Based Learning in the STEM Classroom.” Here’s a link to the Google site I used to support my workshop. You’ll find links to a variety of resources to help teachers get started using a PBL approach in their classrooms – handouts, videos, project ideas – plus tips on how to plan, manage, and evaluate PBL. I included some Google forms as collaboration tools. They didn’t get much action, but they had potential for collaboration. (I reset them to no longer accept new data.)

Solve This Problem, You’ll Learn the Skills Along the Way

Wisconsin STEM Summit I’m in the Wisconsin Dells today to deliver a four-hour training session for CESA 6. It’s entitled “21st Century Skills in Action: Project Based Learning in the STEM Classroom.”  We’ll be using a Turning Point ARS and lots of activities so that participants experience the why, what, and how of PBL in the STEM curriculum.

Students explore their world with an expectation of choice and control that redefines traditional notions of learning and literacy. Educators are discovering that they can motivate students with a PBL approach that engages their students with the opportunity to behave like STEM professionals while solving real-world problems.

I was pleased to read an interesting piece in the NY Times on yesterday’s flight. “Computer Studies Made Cool, on Film and Now on Campus” (6/11/11). While the focus is on the growing popularity of computer science, it make a strong case for the project based approach to learning. 

The new curriculums emphasize the breadth of careers that use computer science, as diverse as finance and linguistics, and the practical results of engineering, like iPhone apps, Pixar films and robots, a world away from the more theory-oriented curriculums of the past.

The old-fashioned way of computer science is, ‘We’re going to teach you a bunch of stuff that is fundamental and will be long-lasting but we won’t tell you how it’s applied,’ ” said Michael Zyda, director of the University of Southern California’s GamePipe Laboratory, a new games program in the computer science major. With the rejuvenated classes, freshman enrollment in computer science at the university grew to 120 last year, from 25 in 2006. …

To hook students, Yale computer science professors are offering freshman seminars with no prerequisites, like one on computer graphics, in which students learn the technical underpinnings of a Pixar movie.
“Historically this department has been very theory-oriented, but in the last few years, we’re broadening the curriculum,” said Julie Dorsey, a professor.

She also started a new major, computing and the arts, which combines computer science with art, theater or music to teach students how to scan and restore paintings or design theater sets.

Professors stress that concentrating on the practical applications of computer science does not mean teaching vocational skills like programming languages, which change rapidly. Instead, it means guiding students to tackle real-world problems and learn skills and theorems along the way.

“Once people are kind of subversively exposed to it, it’s not someone telling you, ‘You should program because you can be an engineer and do this in the future,’ ” said Ms. Fong, the Yale student. “It’s, ‘Solve this problem, build this thing and make this robot go from Point A to Point B,’ and you gain the skill set associated with it.” With other students, she has already founded a Web start-up, the Closer Grocer, which delivers groceries to dorms.

Putting the Problem First Can Create the Knowledge

Dan-meyer-math As I blogged in my Apollo 13 video post,  Watch Problem Based Learning in Action  ”While our students have been conditioned to ‘learn the basics – then solve the problem,’ that’s not how life always works.” 

Here’s a great 4-minute video by Dan Meyer that gives three examples of how to bring real-life problem scenarios into the math classroom.  To paraphrase Dan, “In these examples student have to first ask the question – what information do I need to solve this problem? The textbook usually gives you that information. But here students build the problem and decide what matters. The question that’s usually buried at the bottom – it’s the last thing in the textbook problem – now becomes the first thing in the student’s mind. I want to make that question “irresistible” to the student, so they have to know the answer.”  For more great ideas on how “math makes sense of the world” – go to Dan’s blog dy/dan

What Would Schools Look Like, If Students Designed the Schools?

Independent 4 As you watch this video, think about what could happen in schools, if adults got out of the way. 

You’ll hear students say things like,  ”A subject comes up that I don’t know about, and instead of glossing over it,  I truly find myself thinking was is that about? I could learn about it! I’m finding questions in everything.” And “We learned how to learn, we learned how to teach, we learned how to work.”

Of course, it’s easy to discount these kids as atypical. Marginalizing them is far easier than wondering why other high school students are stuck doing worksheets.

Stop Worrying About Shanghai, What PISA Test Really Tells Us About American Students

The latest results from the Program for International Student Assessment (PISA) are public, and already some pundits are declaring it “a Sputnik wake-up.” Others shout back that international comparisons aren’t valid. Rather than wade into that debate, I’d rather look more closely at the questions in the PISA test and what student responses tell us about American education. You can put international comparisons aside for that analysis. 

Are American students able to analyze, reason and communicate their ideas effectively? [Think Common Core standards] Do they have the capacity to continue learning throughout life? Have schools been forced to sacrifice creative problem solving for “adequate yearly progress” on state tests? For more on that last question see my post “As NCLB Narrows the Curriculum, Creativity Declines.” 

PISA provides some answers to those questions and offers an insight into the type of problem solving that rarely turns up American state testing. FYI: PISA is an assessment (begun in 2000) that focuses on 15-year-olds’ capabilities in reading literacy, mathematics literacy, and science literacy. PISA assesses how well prepared students are for life beyond the classroom by focusing on the application of knowledge and skills to problems with a real-life context. For more examples of PISA questions and data click here. 

Do American students learn how to sequence or simply memorize sequences

Here’s one insight into what American students can (and cannot) do that can be gleaned from the 2003 PISA test results. We spend a lot of time in school getting students to learn sequential information – timelines, progressions, life cycle of a moth, steps for how to. Typically the teacher teaches the student the sequence and the student correctly identifies the sequence for teacher on the test. Thus we treat a sequence as a ordered collection of facts to be learned, not as a thinking process for students to use.  This memorization reduces the student’s “mastery” of the chronology to lower order thinking. I was guilty of this when I first started teaching history “Can someone give me two causes and three results of WWII?” 

Sample sequencing problem from PISA

The Hobson High School library has a simple system for lending books: for staff members the loan period is 28 days, and for students the loan period is 7 days. The following is a decision tree diagram showing this simple system:

Pisa-1

The Greenwood High School has a similar, but more complex library lending system:
All publications classified as “Reserved” have a loan period of 2 days.
For books (not including magazines) that are not on the reserved list, the loan period is 28 days for staff, and 14 days for students. For magazines that are not on the reserved list, the loan period is 7 days for everyone.
Persons with any overdue items are not allowed to borrow anything. 

Task

Develop a decision tree diagram for the Greenwood High School Library system so that an automated checking system can be designed to deal with book and magazine loans at the library.  Your checking system should be as efficient as possible (i.e. it should have the least number of checking steps). Note that each checking step should have only two outcomes and the outcomes should be labeled appropriately (e.g. “Yes” and “No”).

Student Results

Only 13.5% of US students were able correctly answered the question. Does it really matter if students in Shanghai did any better? (The student results were rated on a rubric scale.) 

When students are asked to observe a process and develop a sequence they have an opportunity to use a full spectrum of higher-order thinking skills – they must recognize patterns (analyze), determine causality (evaluate) and then decide how they would communicate what they’ve learned to others (create). Sequencing can be taught across the curriculum at a variety of grade levels – we simply have to ask the students to observe and do the thinking.

In case you’re wondering,  correct response should look like this.
