How did we choose what to teach in the NGSS?

Greetings everyone!  Just getting back from NSTA and am really charged up (as is the intention of good conferences).  It is really gratifying to talk with so many enthusiastic teachers and administrators with a passion for teaching elementary students about the wonders of the universe.  I still find it a hoot when I get approached by people excited about reading my blog.  It tells me there is a real need to talk about this time of change we are going through, but please don't take my word for it...



 Honestly, the intent of this blog from the beginning has been to put out the path that I am taking not as thee  path, but as a set of ideas to get this process moving.  I want to be questioned and challenged about my ideas.  Indeed, challenge is the path to improvement.  In the spirit of that idea, I have been asked the question in my title several times.  So here is my response.  

I use the topic based arrangement of the NGSS as is.  Each page of performance expectations is the basis for a unit.  My assumption has been that there was some reason the PE's to be bundled this way; although after questioning the writers for confirmation of this the best I got was "these are the ones that seemed to fit together coherently."  In a couple of units, we have to get very creative.  

The grade 3 page on Forces and Motion for example.  It combines classic Newtonian concepts with electromagnetic forces. We can make it work, but it feels very odd.  The Safe Racer program is being upgraded.  It will not only challenge students to keep an egg safe in their cars, but also require them to explain how the magnetic release system we will be adding works.  Along with measuring how far the car goes, we can measure how fast the cars are going by accurately measuring the time it takes the car to reach the end of the ramp.  




In another example, the unit is split into two parts under a coherent storyline.  The Kindergarten Weather & Climate performance expectations have two distinct themes; protecting yourself from the sun and predicting the weather.  Our storyline for this unit asks students to build a structure to protect everyone from the sun while on the playground.  Part 2 asks the students to evaluate weather data in order to determine if they should tell the principal to take down the structure so it is not damaged by severe weather.  We actually have students evaluate the radar image.  It is easier than you think.  Break it down into two parts.  What colors symbolize severe weather and what direction is it moving?




So why not cherry pick the NGSS like so many publishers are doing.  For one, the NGSS is built on learning progressions.   This focus on progressions makes science cumulative.  When I talk to principals and other officials, I tell them to think about science like math now.  Imagine what would happen if schools stopped teaching math from K-5.  There is no way middle schools would ever compensate for that lost foundational knowledge.  That is science in an NGSS world.
  
My second concern in a buffet approach to the NGSS is orphaning a performance expectation.  I did not want to get to the end of curriculum writing and realize we missed one.  The one exception to this was in grade 5.  I shifted the PE on people improving the environment (5-ESS3-1) from the Earth Systems page to the Movement of Energy and Matter page.  That was the topic of my last blog entry.  

Lastly, I have ignored the engineering PE's as a separate entity.  It felt too much like the days when we "wove in" the old skills and processes.   Each unit, so far, has students working collaboratively to build a physical object.  That may be a model (beach erosion prevention), prototype (biomimicry solution), or fully functioning object (hand pollinator for example).  In this way, students are learning to act as engineers within context.  

As always, context and relevance are of extreme importance to me.  We are a practical species.  We tend to care about things when they are important to us.  I attended a pre-conference session by Megan Bang.   One of the great points she brought up is that we have to stop expecting our students to ask questions and respond based on our cultural norms.  What does that mean in this context?  Curriculum developers may find the phenomena of science exciting but until students see themselves connected to it, they will continue to ignore it.  As you read through your curriculum ask yourself these two questions from the perspective of your students.

Why am I learning this?
What will it help me to do?

Coming Out of the Fog: Getting Clarity on NGSS Unit Structure

I have had the opportunity to meet several members of the NGSS writing team at the NSTA conference.   So, you know me, I started asking them with questions.  

  1. How were the topic pages organized (this has preoccupied me for months)?  The most logical response has been that through the process of development, the team joined the PEs that would hang together under a theme.  
  2. Were specific culminating events/performances in  mind when they organized the PEs?  No, they were specifically told not to do that.  The committee did not want to appear to dictate curriculum.
  3. I asked about my proposed structure of using the topic pages as the basis for units.  The major concerns were student endurance and force fitting.  Looking at some of the unit lengths, I can see the endurance issue.  The grade 3 "Forces and Interactions" topic pages is going to be a long unit.   
  4. This particular page  brings me to something that I have been feeling lately as I watch the direction of some of the unit outlines my team is developing.  So, here is the revised plan.  If it fits and is logical, write it as one unit (see "Bee and Engineer").  If it feels forced, make it one storyline but with "sub-units" with specific performance assessments.  
My current curriculum has an example of this idea.  Last year, we re-developed a unit that had some serious implementation issues.  It covered Newton's Laws and for unknown reasons also included light (reflection, refraction).  The masterful writing team created a unit scenario focused on the Orion Deep Space System.  Students built straw rockets to demonstrate their understanding of Newtons Laws.  Part 2 of the unit, challenged students to create a "visual docking system" for the crew module (aka Periscope).   See image below.  The astronaut sits in the position shown but has to see out the window.  Build a device that will allow the astronaut to see out the window in order to dock if the ISS.

Hitting the Air Waves

I had the great fortune to participate in Lab Out Loud, NSTA's podcast for teachers and by teachers.  It was such a hoot talking with Dale and Brian having listened to them for the last couple of years on my commute to work. You can listen to the interview here are at the Lab Out Loud site.
