A Simple Vector Development of Centripetal Acceleration

Dave Doucette, OAPT Vice-President
doucettefamily@sympatico.ca

While teaching uniform circular motion in high school, I struggled with developing the ac = v2/r relationship in an intuitive and cognitively meaningful way. Geometric arguments do not resonate with students. They accept on faith but often with little interest or insight. Here is an approach that may do a better job. Read More...

The Intersection of Science and Small Contractor House Construction

Dave Gervais, Chair STAO Safety Committee, construction worker

The options for your students that drop out of high school or graduate with high school are very limited. After rolling through the low paying jobs of the service sector, restaurant or retail business, construction work looks pretty good. How do the science and mathematical principles and calculations in construction compare to that taught in our science classes? Read More...

Webinars and Video Calls in the Classroom

Stacey Joyce, Program Manager at Partners In Research Canada (PIR)

I’m sure that you employ a variety of tools and strategies in your classroom, including inquiry activities, independent or group projects, “assessments as, for and of” learning… the list goes on. But how do you and your students answer the questions they come up with during or after the initial inquiry activity? What types of resources do you teach students to use for their independent research? How do you introduce the students to career options that use Physics?

Here’s where video calls and webinars come in, and don’t think that you can’t afford these options — they’re free from Partners In Research Canada (PIR)! Read More...

New Recommendations for the Safe Use of Laser Pointers

David Gervais, Chair STAO Safety Chair

STAO’s Safe on Science booklet is a great resource for teachers and is used as the standard for safe practices by many school boards in Ontario. It presently states that only class 1 and 2 lasers should be used in the classroom. This bans almost all laser pointers from your classroom. A recent OAPT Newsletter article questioned why class 3R lasers (most regular laser pointers) are not accepted. After carefully reviewing the literature and holding extensive discussions, STAO has decided that laser class 3R should be added for recommended use in schools. The Safe on Science booklet is being revised and will be completed by March 31. This will be sent to school boards in the province. Read More...

The Power of Quiet

Roberta Tevlin, teacher Danforth CTI, editor OAPT Newsletter roberta.tevlin@tdsb.on.ca

Edited by Tim Langford, Chris Meyer

Physics Education Research has provided solid evidence that lectures may be good at transmitting knowledge but poor at developing understanding and so we should implement student-centred learning in our classrooms. However, Susan Cain, the author of the 2012 best-seller Quiet: The Power of Introverts in a World That Can’t Stop Talking is very dismissive of the way group learning is replacing lectures. The book’s central premise is that our culture is too strongly slanted in favour of extroverts and they way they work and learn.

At first, the anti-group work message of the book just got my back up. I read it so that I could refute it. Further reflection has made me realise that it provides some important insights and even fits well with this year’s conference theme of Affective Physics. Read More...
