Use the Design Process to Engineer a Student-Centered STEM Project ● March 25, 2020
I am sure you are all feeling the pressure of the Coronavirus outbreak. The map of US education is looking really bleak. But even in Virginia, where the buildings won't open for the rest of the year, there's still a lot of teaching going on, so I'm sure you're all working as hard as you can muster!
I met yesterday with a group of teachers from Virginia who are going to use the engineering design process to design a final integrated STEM challenge for their students. You are more than welcome to take or modify this idea.
These teachers teach a three-year integrated STEM course (biology, chemistry, physics, design technology, engineering design, geometry, algebra II, trigonometry, and precalculus), and they want all of their students to be on the same page, so they're going to use this process with all of their grades (9th, 10th, and 11th) but differentiate the final project requirements down in Phase 4. You'll also see some differentiation throughout.
- Problem Definition phase: The teachers are going to send a survey to their students to gather some information about their availability, available resources, interests, their goals for next year (which science course they intend to take, etc.) and concerns. Also, their interest in continuing the space debris mitigation challenge that they were already working on.
- Design Exploration phase: The teachers will use the student data to come up with several proposals for the last unit to be done completely at home. They expect to propose that the students should invent a design challenge that is somehow related to the Coronavirus problem and related to their choice for IB science next year. For instance, the challenge could be in the realm of networking social connections (computer science), in the realm of personal protective equipment (biology), in the realm of online learning (CS?), transportation (physics), etc.
- The teachers will propose that the students can pick their own groups or work alone, that they can make a physical or digital conceptual model or working prototype, and that the students will need to record an audio + slides presentation to share for feedback.
- They will also propose resources that can be made available. Right now they're thinking of offering videos, webinars (recorded), web resources, digital assignments and online office hours.
- The level of academic rigor expected will be to incorporate at least the depth of learning that they've worked on this year (kind of like a capstone) and the teachers will scaffold more particular content into the online materials depending on the grade of the student. This provides the opportunity for the students to show the utility of the knowledge they've been constructing. For instance, the 9th-graders are supposed to be heavier on biology (although this course is integrative and all mixed up.) So, for instance, the biology students will need to hit a significant level of depth when explaining why their design challenge is appropriate in this era based on the biological factors at play, the anatomy of the virus, say its lipid layer, etc, and why their design is too. We can imagine a physics kid who's inventing a hand-washing waterfall would need to talk a lot about potential energy, the velocity of the water, as well as the properties of surfactants.
- The students will also need to tether their design challenge and actual design to at least one of the Grand Challenges for Engineering in the 21st Century in a compelling way (this is always a requirement in this course.)
- This school is not clear about what grades will look like yet and whether this interval may be graded or not (there's going to be so much inequity of experience, it's going to be really hard to suggest they be graded.) The teachers will propose self-assessment instead of grades. They will also let the students know that volunteers will be assessing their designs and that the only way to be entered into that pool will be to remain "in good standing" completing check-ins and hitting the "mile-markers" that the teachers expect to set up (such as, you need to give me your design challenge by xx, you need to select from your design ideas by xx, etc.)
- Design Optimization phase: The students will provide feedback on the proposal to the teachers.
- Design Communication phase: The teachers will construct and send the final project description doc and expectations to the students. We don't have this yet (the conversation was yesterday) but they expect to have it together by the end of next week. The final due date on the students' projects will be May 22 allowing for one week of reviewing by outside volunteers and peers before the last big end-of-year reflection.
If this seems like a lot, you're not wrong, but this is eight teachers spanning three years. They usually have the kids for 4.5 hours every other day. Instead of thinking, "This is too much!" consider joining forces with your math, tech, business development, history, or other science teachers. This project idea could satisfy a lot of content areas and be extra motivating in combination.
I'm dying to know: what sorts of teaching from home are you doing if any? Are you required to do something or do you have freedom to make some choices? Feel free to be in touch if there's anything I can do for you or your students at this time. Check out the Google sheet of engineering-related challenges that can be done at home here. Please note that there are also tabs for elementary and for Teacher Self-Care including offers for free workout stuff free journaling papers, etc.
Take care out there!
Predicted Teacher Tradeoffs When Trying Engineering ● December 5, 2019
I was reflecting today about some things I've noticed that can act as roadblocks when teachers are asked to integrate engineering into science. I wonder if any of these ring true for you or your colleagues?
Content insecurity--people feel like this engineering thing will require more content knowledge than they possess which will lead to them being exposed as less than absolute authority in their content area.
Instructional inefficiency--teachers feel like they'll blow it on teaching content if they do this weird engineering design thing, which will waste their time and let their students down. Or at the very least, they think this will take longer than their usual instruction will take.
Classroom chaos--teachers fear that their classroom will erupt in noise and mess which could have real consequences for safety, for the next period which is not doing this project, or might be perceived by other staff, students, or admin that they have no "control." Worse still, they might think that there will be so many proverbial "fires to put out," i.e., groups to talk to, that they'll be running ragged or leave some kids hanging.
Clearly, this is not an exhaustive list, but I do see these often! If these do sound familiar, then fear not--these are common issues and should really be seen as evidence that you've successfully pushed people's thinking and challenged them beyond their comfort zones! To counter these, I think of each one as a tradeoff and try to address the issues head-on instead of pretending that they're not a big deal.
Content insecurity is real and you might feel like you're going to be pushed, but if that happens, admit it and let it be a demonstration of a growth mindset. Tell students that they have surpassed your expertise but you are super excited for them to come through for you with new content knowledge. They have raised the bar of your expectations--the new bar includes addressing this content gap or at least justifying why or why not it matters to their thinking and their design.
Instructional inefficiency is real too. Especially the first few times you teach something in any manner you almost certainly are less efficient than when you teach it in your tried and true way. However, the tradeoff with engineering design, as with PBL or inquiry or individual research, is that the learning is so much deeper and more interconnected to students' other thoughts and knowledge. And that's definitely worth it. Don't forget that your measures of learning might need to flex to see this level of complex thinking. Consider asking for concept maps and analysis of real-world novel problems on your assessments in addition to the straight-forward traditional questions.
Last one, classroom chaos is real too! It will feel nuts! Take a proactive approach to mitigate the chaos:
- Tell your admin ahead of time that you're doing this awesome thing and it will be chaotic. Tape a "Designers at Work" sign on your door.
- Try having the materials that kids can use out already so that you're not running to and from the supply closet. If it's not out, it's not available.
- Try making an instruction sheet for the equipment your using and have one at each lab station. They should consult that sheet before bothering you to ask where the On button is.
- Or grab one person from each group to demo the equipment with and then send them back to their groups. If they get stuck, tell them to ask someone else who was at that small meeting before they come to you.
- Knowles Instructor Corinne uses green, yellow, and red Solo cups to indicate: "We're cool and coasting", "stop here when you can," and "ROADBLOCK!" respectively. Then the kids are in charge of reflecting on their problem, not just stopping and quitting.
- And most importantly, try to remember that YOU aren't solving the problem for them, the point is THEY are solving the problem. Feel free to say, "I'm not answering that for you" instead of trying to break it down on the spot. You can even say, "I'm under defining this on purpose and won't offer help" ahead of time. Their creative brains will take over if you set the expectation that they must engage.
PBL and engineering compatibility? ● August 2, 2019
Boston teacher Mark Soo asked the following question about PBL, Shared with Mark Soo's permission:
"I attended the mini PBL session this Summer Meeting, and the project I was working on involves students creating a transportation plan for the city of Boston. I'm planning on asking them to come up with criteria to evaluate different transportation solutions, weight those criteria according to what's most important to them, and then apply the criteria to choose a "best" solution to the problem. Brian indicated that you might have some expertise that I could use to help me out.
"At the end of the mini PBL session, I have a rough project idea, an analysis of the science practices I want students to use, and a rough outline of the content I want students to understand. If you have any suggestions for planning or implementation, I'd love to hear them!
"Thanks for your time,
I like your idea! It feels pretty huge though, so I suggest you also consider using constraints and criteria to help limit the problem space they're working in. By this I mean, you can give them the chance to come up with their own priorities in addition to ones that you use to rein it in. I'm attaching an example of this where someone said "it has to go at least 1.5m and be videoed for the whole flight" and then had students choose from among the two options: be as accurate as possible, i.e., hit a target, go as far as possible. She didn't want them doing "As high as possible" because they might want to go outside, etc. It was a strategic move. See what I mean? If you like the format, there's a blank one for you to adapt here (all links to tools point here: https://sites.google.com/knowlesteachers.org/knowlesengineering/tools-for-teachers).
You might want to check out some of Knowles Engineering's tools for teachers. I know this is a PBL project, but you can definitely use PBL strategies and engineering strategies together. For context, Knowles engineering generally follows a four-phase design method and some PBL routines are embedded within each of the four phases. For instance, in this inputs/outputs document. we show what a student might receive to work in a particular phase, what they might be doing during each of the phases, and what the output of their decision-making in that phase might be,
You'll see that in the first phase of the design process, problem definition, they are making a PBLish know/need-to-know doc to help them organize their thinking about the problem, but that's not the only thing they can be doing to better understand what they'll need to do. We've developed tools for basically everything mentioned in there, but most of them are also google-able, well-known techniques that you, or your students, could select among.
Just one more thing, because I'm sure this is plenty!, you might find our complexity rubric useful. As you plan I'm sure you're going to be thinking about differentiation and how you'll scaffold for all students to succeed, but that might be hard and even intimidating to the point of paralysis. The complexity rubric is designed to help you think about the amount of student demand versus teacher-provided resources that you deploy in a design challenge, essentially changing the cognitive load on the students. "Novice" and "advanced" are really not about the status of your students or the project's success as an engineering design challenge, so please don't feel like you need to be advanced all over the place. The rubric items are about student lift, and listed to provide you a chance to reflect on where you're asking them to exercise independence and where you're supporting them more. It will be natural to have some turned up and some down. If you have very independent students, you might ask them to do the more advanced version of one row while you scaffold the novice version with other kids.
We do have a rubric for the design process. If it helps you, awesome. It's not a rubric for the final output, but provides some language for expectations various moments in the unit, including a reflection moment, which is important for synthesizing the whole project from a learner stance. This whole rubric is pretty dense, so we recommend using a line of the rubric here or there, maybe adding one line to your own rubric, or having students use a few lines as a reflection prompt.
I hope some of these ideas or other tools on our site will help you! Let me know if you have more questions, please. Or if I've missed the mark and you're looking for help in another way, just email back and let me know.
