Thoughts on Teaching Engineering Practices

Standard

I am teaching Engineering this year. In this class, I really do feel like a mentor in the room, a partner in learning. I think the big difference is that the class really is project based. I haven’t quite figured out how to assess appropriately just yet, but I am sticking to the “here’s a problem, GO!” mentality. Our most recent one looks like this:

And here are some students working on it:

(note: Not staged. And I assigned no roles, just the problem.)

The kid on the left is modeling a plastic holder for a magnet that will have a name embossed on the side. He’s learning and practicing  skills in Autodesk Inventor (our 3D CAD software). He chose this role in the group as he is passionate about 3D modeling and printing.

The kid in the middle is measuring the magnets with a dial caliper. He is learning about precision in measurements and asked some excellent questions about significant digits.

The kid on the right is documenting the process in her engineering notebook. She has assigned herself this role because she is thorough and has a good eye for detail. She also keeps the group on track by doing this.

All three of them are learning and practicing communication and collaboration skills to solve this problem. They had to clearly define the problem and then brainstorm solutions before getting to this point. And now that they’ve arrived at their potential solution, they are working together to develop it.

So, I think they are hitting NGSS Practices 6 and 8 in particular:

6. Designing solutions in engineering

8. Obtaining, evaluating, and communicating information

But do I want a “Teamwork” section on my rubric? If so, what exactly makes a high score in “Teamwork”? Clearly, these three kids are rocking it. But what about another team that has a different dynamic? It’ll be hard to judge, but does mean I can’t? Not sure.

So here’s my rubric for now. My plan is to have the teams assess themselves with this rubric and then turn it in as part of their project portfolio.

How Do I Level Up?!

Standard

I’ve been getting this question a lot, so it has become clear that I needed a better explanation for what Level 1 means (see this post for explanations of all three of my levels). So team Socratic Brain came up with this list of questions.

Bonus: Here’s our Constant Velocity model summary! See if you can spot the subtle mistake in there that I haven’t had a chance to fix yet.

Update on the new #SBL scheme

Standard

Here’s the plan as it is now:

Step 1: Students complete some learning activities! Sometimes these are whole class, teacher directed (like a 3-act or something). Sometimes they are individual, student paced (like a guided handout). All activities exist on a Blendspace page for each learning target. If an activity covers multiple targets, it exists on multiple pages.

Step 2: Students complete some practice (usually). If a learning target is not easily assessed in a multiple choice or numerical response question, this step can be replaced with some reflection questions, like “what did you learn from activity ____ ?”.

Step 3: Teacher conducts brief “interview” with each student to check for understanding. The student should be able to show their completed activities and practice work, AND be able to explain what new skills and learning were acquired. (Note: this earns the student Level 1 on a target)

Step 4: Students take a separate quiz on each learning target. Some LTs will be better suited to multiple choice or numerical response, and some will require a constructed response. Possible results:

  • Student aces quiz, earns Level 2 for the LT
  • Students misses one or more items on quiz, keeps Level 1, but does not level up. To earn a second shot at the quiz, student must complete any extra learning activities (as there are usually more than the required amount), or redo the practice, or both.

Step 5: Students reach Level 2 (have aced the quiz) for ALL LTs in the unit. Then, and only then will they gain access to the Level 3 task. This task covers all the individual LTs and is never computer graded. An example from Physics would be our Energy Screencast task, in which students choose a YouTube video and thoroughly describe all the energy exchanges taking place in the video. Each Level 3 task is accompanied by a rubric that indicates exactly the things we are looking for. For the Energy Screencast example, we would include:

  • make reasonable estimates of relevant heights and distances, in meters
  • define the system in which energy flow and transfer is to be modeled
  • model energy distribution within the system using bar graphs

…among others.

Step 6: Teacher reviews the Level 3 task entry and uses a rubric to indicate mastery of each LT (or not). For instance, let’s say a student turns in a screencast in which they successfully estimate the relevant heights and define the system, but do not include bar graphs to model the energy distribution. In this case, the student earns Level 3 status on the first two LTs, but stays at Level 2 on the bar graphs one. (Note: This could even have been part of this student’s plan. A unit with at least 3/4 LTs at Level 3 will still calculate as an A for the unit and students will know this.)

Let’s see how this looks! 🙂 My colleague has been working on some upgrades to our system (same name SocraticBrain.com), but it’s not 100% ready. For now, here is a partial screenshot:

screen capture2

Notes: When you click on “Practice”, it shows whatever the teacher puts in as practice for that LT. So, in the case where a multiple choice item is not appropriate, the teacher could include a link to something else, or just a few reflection questions. When you click on “Level up” it gives you the next level task (whether it’s the Level 2 quiz or the Level 3 performance task). If the button says “Not Ready”, then when you click it, it tells you what you’ll need to do to get ready.

Some things I love about this system: 

  1. Students must demonstrate some level of understanding before “leveling up”. I’ve struggled with how to help students who fall into the habit of “I’ll just take the quiz over and over until I figure out the pattern”. With this system, the teacher is in control of access to the quiz, so if they want a try at it they have to show what they’ve done to earn it.
  2. I LOVE how the Level 3 task becomes the focus of the unit. One big failure of mine from last year was not providing summative tasks that combined LTs. In this system, the only way for a student to get an A for the unit is to complete a task that does exactly that (combines multiple LTs).
  3. Last year, we had a big problem with students turning in Energy Screencasts that showed a clear lack of basic skills and understanding. It was way too time consuming to provide appropriate feedback on those. The hope is that by requiring Level 2 status on ALL LTs before attempting the Level 3 task, we will avoid this problem. Then, we’ll be able to really push students further with our feedback, instead of pointing out simple mistakes and omissions.

What do you think? Any advice or feedback is appreciated!

[Gamification] Must-Have Game Element #1

Standard

So, I’ve decided to look at the different game elements I want to bring to my class one at a time, in order to assess the strengths and weaknesses and decide which ones will best benefit the learning process. I’ve already put a few into the “must-have” category, so I might as well start with those.

First up is the health meter.

20140129-174920.jpg

These are used in games to indicate the health or life force of a character. When the character is hit by something, the meter goes down (or loses a heart). What makes the health meter different from points or gold is that it starts out full and goes down when something bad happens. And if your health reaches zero, you die. 😦

What need does the health meter fill?

Practice assignments need to get done, whether they’re done at home or at school. If a student is not practicing their skills, they run the risk of being ill prepared for the more important task of completing quests/missions. So I want to track progress of practice assignment completion, but I also want it separate from any sort of proficiency measure (just because you did the practice doesn’t mean you understood it). So, I plan to use the health meter for this.

Miss a practice assignment, lose a heart. Simple. Want to get that heart back? Drink this potion. Do the practice and show it to me. If you lose all your hearts, come in after school so we can talk. Why have you not been practicing? What can I do to help? Do we need to bring your parents into this?

I think this also may help with the “I was absent” excuse. It doesn’t matter one bit why you missed the practice, you missed it so you lose a heart. Do the practice, get it back.

And I can give rewards for keeping full health, like extra XP or gold or something tangible that they want and doesn’t cost a lot.

Please let me know any thoughts you have on this one! I know I haven’t looked at this from all angles yet, so I need some help.

iPad Formative Assessment

Standard

So, I’ve been using my ipad pretty much every day. I mainly use it as a sort of mobile document camera, snapping pictures as I walk around. I usually then project the work on the board and ask students to explain it for the class. This gives me a chance to ask some good questions like: “Why did you multiply by 99 instead of 100?” “Is there really a force pushing on he ball?” “If your rule is +2 every step, how many will there be in the 73rd step?” Sometimes we spot mistakes, sometimes I purposefully get two pics to compare, sometimes we are surprised by different methods, always good learning happens! I’ve got hundreds of these now:

Function Notation Can Wait

Standard

It has been way too long since I’ve blogged, but from what I’ve been reading lately I am not alone on this.  Like many others, I have been feeling a little overwhelmed this year.  It is tough trying to keep up with new curricula in Algebra and Physics, and I’m basically constructing my textbook as I go too.  </whine>  So far, I’m happy with the way things are going in both classes.  In Algebra, I’m using the learning targets that I wrote over the summer (modifying as I go of course) and I’ve been using a bunch of the handouts from Connecticut’s model Alg 1 curriculum (click “CSDE” then “Mathematics” then “CT Common Core Alg 1”, thanks to Jen Silverman for sharing that resource with me!).  If you teach Algebra I or MS Math, I’d give them a look at least. (Edit: guest password is CSDE.)

I’ve also been writing a class blog to keep in touch with students and parents.  That blog also serves as a model for my students when they finally start their blogs (we have them set up but haven’t started posting yet).  I’m thinking maybe we should do an Explore-MTBoS-style series of missions! Gotta get to work on that with all my free planning time. 😉

A highlight for me this year has been doing a lot of problem based lessons.  Some I got from the CT curriculum, but mostly from online sources like MARS, 101qs.com, or the twitterblogosphere in general.  I’ve really been enjoying this type of lesson and I think most of my kids have too.  Many parents told me at back to school night that their kids were enjoying the class.  However, I’ve found that many kids are struggling to make the connection between the lesson and the assessment (I have the same problem with modeling instruction in physics).  My worry is that if I don’t come up with some fixes for this problem, I’ll revert to old ways and abandon the problem based course design (which I think is going well otherwise).  Anyway, here’s an example of my assessment scheme:

First, the lesson handout:

So, we did this handout.  As a class, we noticed that the cost would depend on whether or not the dog needed a bath each visit.  We decided that it was a dirty dog, so yes it did need a bath every time.  Then, we wondered which would be the better deal and decided that it would depend on how many times you visit the place.  With some guiding questions, groups of kids modeled the scenario, made some nice TI and Desmos graphs and most decided that they should go with  Super Dog Delight because it would be cheaper in the long run.

Ok, so one of the skills I am looking to assess after this activity is solving equations with variables on both sides.  Here’s how I did that:

1.  Formatively assess during the activity.  Notice the different methods for writing and solving equations, point them out to the whole class.  Have students demonstrate their methods.  Celebrate mistakes!

2.  Multiple choice summative quiz.  5 questions, randomly generated by Socratic Brain (according to my specifications).  Students must get 5/5 twice (on different days) for full credit.  They can take the quiz as many times as they need to.  Questions look like this:

Screenshot_101613_034503_PM

3.  Screencast!  Our school got an iPad cart (20), so I checked it out and had students make screencasts explaining their solutions to a particular equation.  Here’s an example of one.  He made some nice mistakes in there.  I gave feedback, but I’d love to work out a system where they view and critique each other’s screencasts (working on it!).  We also used Infuse Learning to practice literal equations:

4.  The Exam.  So, to assess this skill one more time, I have a scenario similar to the Dog Spa problem on their quarter exam.  My strategy on the Algebra exam is inspired by a History teacher I had in high school who would give us essays on every test, but let us know the topics beforehand so that we could prepare.  I decided to try something similar by giving the students the scenarios, but not the questions.  Here’s what I showed them:

And here’s the questions I asked:

And I gave them some class time to prepare for them.  I told them to think of questions they have and how they might go about answering those questions.  I also told them to think about what questions I might ask and how they would answer those.  Feelings about the exam were mixed.  Some students were excited that I was giving them a peek at the exam, but others were confused as to how to proceed because of the lack of questions.  I think the latter group of kids is the group I referred to earlier.  They’re the ones who are not making the connections between the activities we do in class and the skills required for the assessments.  Like maybe they participate in the group activity by making a graph, but then never learn about writing an equation (“my part’s done here”).  Now that I’m thinking about it though, it seems like the solution might be more problem solving activities, not less.  That would mean more chances for that kid to write some equations, right?

So why the title “Function notation can wait”?  Well, I started the year with my Unit 1 called “Modeling with Functions”.   But, I found that my students were thrown off by the notation and it was hurting the learning process.  For instance, we did the checkerboard border problem 3-act-style (thanks to Dan Meyer for the fancy graphics).   Here’s a few examples of what they came up with:

photo (3) photo

They explained how they saw the pattern very well and then also used function notation in their equations.  But when I asked them to explain why they wrote the equation that way, I got “Because that’s how you did it”, and that’s not what I want!  They should use function notation because it’s useful as a labeling tool, not because I said so.  Other groups wrote the equation as (# of blue tiles) = 4*(width of smaller square) + 8, which I like much better anyway.  I don’t want to confuse anyone when they clearly get the idea conceptually.

So, new title for Unit 1: Patterns and Modeling.  Function notation can wait.
