Surrey Focus Day Pro-D Workshops

At the Focus Day on February 16, I presented 2 workshops on scientific argumentation. Here are the links for each workshop. You will find the PowerPoint presentation and supporting documents.

Provoking Student Thinking

Provocations are new to me. As a secondary teacher, I have never used provocations in my teaching. In my new role as District Science Helping Teacher, I work with elementary teachers all the time so I have been exposed to provocations more often. And in my typical professional manner, I am stealing this idea to use it in my classroom.

I recently had an opportunity to share a workshop with my Helping Teacher colleagues. I led them through a lesson on friction using friction blocks and spring scales. I wanted to start the lesson with open play so I created some provocations.

I attempted to craft the provocations to draw out specific learning. In particular, the question: "How slowly can you move the block?" is intended to allow students to observe something specific. Using a spring scale to pull the block, students should notice that the force required to start the block moving is larger than the force required to keep it moving. Pulling slowly makes this very obvious. The spring scale reading will go up, up, up until the block starts to move. Then the reading will drop suddenly as it begins to move. In my physics classes, about half the students notice this on their own during the lab. The provocation is intended to ensure that all students observe this happening.

Of course, I underestimated the creativity of my colleagues. One person picked up the block and moved it very slowly through the air. The block wasn't sliding so no friction. No spring scale was used. There was zero chance to observe what I had intended.

And that is my fault. I thought I had crafted the provocation in a way to get at the noticing I wanted to happen. But my wording allowed for alternate methods that didn't allow for the noticing I wanted. I realized I need to change some words.

What do I really want to happen?

  • I want students to pull the block so it slides across the table because there needs to be friction.
  • I want students to pull the block using a spring scale to see the reading change.
  • I want students to pull the block slowly so the change is obvious.

So my provocation needs to be more specific to make sure these things happen. Here is my new provocation:

What is the smallest force you can use to slide the block?

  • The word slide ensures there will be friction.
  • The word force ensures they will use the spring scale to measure the force.
  • The word smallest ensures they will pull slowly so they can observe the change.

Intentionally crafting the provocation provokes the learning I want my students to experience.

Science Inquiry Resources

Last year, I hosted a series of after school workshops about science inquiry. I posted my PowerPoint slides and handouts on my Google Drive and put links to the various grade levels here on my blog. But each link was a different post and hard to find. So I am deleting those posts and putting a link here to the main folder.

Elementary Science Resources

You will find a folder for each grade level. I may organize the contents of each grade level folder by Big Ideas so it is easier to find what you are looking for. And I will continue to update these folders as I come across new resources and develop new lessons.

You will also find some general documents in the main folder that might be useful. A few highlights:

Simples Strategies to Promote Science Inquiry
This is a list of simple activities that can be used as regular classroom routines. They promote scientific thinking and skill development.

Videos for Science Inquiry in Classrooms
A document with links to various videos showing inquiry in actual classrooms. Many of these are from The Teaching Channel and combine classroom footage with interviews from teachers and researchers. I like these a lot because I can hear about the strategy from researchers and also see it in action.

Card Sort - Animal Classes
This is a new card sort I developed that I am very proud of. I thought it could be used in several grades so I put it in the main folder for all to see. I will continue to do this with activities I develop that can be used across multiple grades.

The Question That Drives My Thinking

"What am I currently doing that the students could be doing?"

When I consider the art of teaching through scientific inquiry, this is the question that drives my thinking.

With the shift in the new curriculum towards inquiry learning, many teachers are struggling with what that looks like. Often teachers I work with have fantastic activities they have developed over the years for teaching specific science concepts. Now they are wondering if they have to throw out these great activities and start over.

But often it is just a small change that can transform the activity. Transferring ownership and responsibility of learning to the students. Here is one example about types of rocks. Here is another example about things that float. In each case, taking away something the teacher would normally do and transferring it to the students completely transforms the activity and opens up opportunities for questioning, exploration, experimental design, and student thinking.

Recently I worked with a small group of Surrey elementary teachers. We explored this question: What makes a good inquiry activity? Here are some of our ideas:

There are some wonderful ideas here. My favourites are productive confusion and thinking skills.

Sometimes, even these aspects of inquiry are not enough. One teacher shared an amazing activity she does with her students about the skeletal system using actual bones from a local butcher shop. She was excited about the activity but was unsure if it was truly inquiry. The activity met many of the criteria we generated that are shown in the picture above.

But, the teacher still did most of the explaining and demonstrating using the bones. After a quick discussion, we decided to get the students to observe the bones and explain to the teacher what they were seeing. And suddenly, all the questioning, observing, exploration and thinking belongs to the students.

ADST Through the Curriculum

I recently had the privilege of working with teachers from Bear Creek Elementary. We explored how the new Applied Design, Skills and Technology (ADST) curriculum can be embedded in content from other subject areas.

As the Science Helping Teacher, I naturally focussed on science content as the vehicle to launch ADST design activities. There is a natural link between science and design by applying science concepts to engineering and building activities.

We started out by investigating some physics ideas with a marble rolling down a ramp. We changed the ramp height, length and material and observed and measured how the motion of the marble changed. This naturally led to a roller coaster design challenge. Lots of curricular and core competencies bubbled up naturally.

Here is a link to the PowerPoint slides and some other documents from the workshop:
