Everybody hates to be tested – especially in public.
But almost anyone loves to solve a problem. That is why some of us spend so much time over the Sunday crossword puzzle (or the game of choice on your tablet). But when the problems we tackle are relevant, when the solutions we reach actually improve our life or somebody else’s, then the feeling of accomplishment is tenfold.
Schools were first designed as places where learning “for tomorrow” would happen. Tests were needed to make sure that the students had really acquired the knowledge that was being transferred into them. Once teachers could acknowledge, via the evidence of the written test, that students could at least reproduce on paper the concepts that had been drilled on their brains, their work was done.
It didn’t really mattered if just a couple of days later all those “learnings” had been utterly forgotten or disregarded.
In life, we learn by doing. We find out what works and what doesn’t. We need knowledge, of course, but we know that data must be used to be valuable. Unused knowledge is like unspoken words: they might be there but they need to get out to do their work.
If you want to play the violin, it is useful to get a hold on concepts and techniques – but unless you put your hands to the instrument, you will never produce music.
Problem (or project) based learning is much more like learning to play an instrument, only that it contemplates you as a part of an orchestra from the very beginning. You need to do your part but you must also work with others to create magic.
PBL takes its time, and, because it’s centered in the students and their interests, it can many times move away from the curriculum we are required to teach – which is not necessarily a bad thing. PBL requires careful planning and lots of flexibility.
Recently, at our school, Colegio Valle de Filadelfia in Aguascalientes, México, we began to teach our students about the SDGs – the UN Sustainable Development Goals. When talking about goal #12, “Responsible consumption and production”, we challenged 7thto 9thgrade students to think about the things they use and consume every day and how they could be improved in a way that benefits the planet. Students worked in groups to identify possible problematic products and to brainstorm for solutions.
One group looked closely at something each one of them used everyday, most of the day: a pencil. They wondered how many trees were cut to produce the pencils they were using (about 82,000 a year, in the US alone). They wondered, could there be a better way? After trial and error, they came up with a pencil made with crushed, fallen tree leaves and other natural components. They submitted their project to a science contest and eventually the team was invited by the government of our state to present their idea at the National Science and Technology week. They spent five days presenting to authorities and visitors alike. Previously, one of the team members, a seventh grader called Natalia, spoke about their project in a TEDx talk – which of course was a new challenge on its own, one that required honing of other set of knowledge and skills, such as writing (for her script) and public speaking.
Not every day is a PBL day, but many are, in some way or another.
Here are the things you should keep in mind when working global project based learning in your classroom or school
- Kids should be part of identifying the problem – that way it will be relevant for them and will not feel like a script they must follow. Give the students some context, of course. When we asked our kids to identify things in everyday use that could be improved to benefit the planet, we gave them a very specific context from where to start. We did not just tell them, “Think about any problem you might want to solve”.
- Students should work in groups. PBL is mostly a collaborative model – being able to pick from many brains makes it much more engaging and productive. And of course, kids develop social skills as well.
- There should always be an outcome –even if it is just an idea that still needs to be implemented. It is OK if the problem is not entirely solved, but we should feel one step closer to finding solutions. Sometimes, just creating awareness about an issue is an improvement.
PBL is an opportunity to use knowledge and skills and put them in action towards a goal. Note that the key word here is “opportunity”, as opposed to obligation. PBL is not a test. It might very well be used to qualitatively evaluate how kids apply and create knowledge, but it is, above all, a new and engaging learning experience.
As part of C.M. Rubin’s Top Global Teacher Bloggers, this is my response to this month’s question: What does a high quality, global PBL program look like in your classroom?
