3D Printing

� Not a new topic� Constantly changing� Increasingly important� Strong connections to education

� but first...

3D Printing is the Next

Industrial Revolution

What educational projects can be “crowdsourced”?

Hybrid technology

Recycled materials

3D Printing comes to school...

Libraries need to become more like kitchens and less like

grocery stores - a place where patrons are able to

construct knowledge, where they can create, build, make

and be actively engaged.

Printing in the classroom...

● Recovers from the loss of tinkering - pride in making something from scratch

● Connects to new Science standards● Connects to Common Core State Standards in

Mathematics

Educational printer requirements...

● Good out of the box experience● Reasonable price● Reliable● Remember it is still early in the game but schools

should start now!

What should students make?

� Avoid just downloading cool things from Thingiverse.� Design is the primary task - printing is the reward.� Create age-appropriate tasks.

NGSS elements

� K-12 Science Education Should Reflect the Interconnected Nature of Science

as it is Practiced and Experienced in the Real World.

� The Next Generation Science Standards are student performance

expectations – NOT curriculum.

� The Science Concepts in the NGSS Build Coherently from K–12.

� The NGSS Focus on Deeper Understanding of Content as well as Application

of Content.

� Science and Engineering are Integrated in the NGSS, from K–12.

� The NGSS are designed to prepare students for college, career, and

citizenship.

� The NGSS and Common Core State Standards (English Language Arts and

Mathematics) are Aligned.

Eight Math Standards: 3D Printing

1. Make sense of problems and persevere in solving them.

2. Reason abstractly and quantitatively.

3. Construct viable arguments and critique the reasoning of others.

4. Model with mathematics.

5. Use appropriate tools strategically.

6. Attend to precision.

7. Look for and make use of structure.

8. Look for and express regularity in repeated reasoning.

3D Printing is a wonderful tool for

developing engineering skills.

We are all designers now. We may as well get good at it.

Subject: Happy to help

I would be very happy to attend the camp and if possible I

would love to help teach. I can have the list of top ten

finished by tomorrow morning and I do have quite a few

models, I have been working with tinker cad For about 3

weeks now and i know quite a bit of information about it,

so I am very confident in my teaching abilities, so if

possible I would like to help teach.
