The document describes constructionist STEM activities using the Bridge21 model that were implemented in secondary school classrooms in Ireland. Two activities are discussed: a bridge design challenge and a mathematical functions activity using virtual marble slides. Results showed that both activities improved students' metacognitive skills and attitudes towards mathematics. The Bridge21 model provided an effective framework for hands-on, constructionist learning. Teacher professional development was also found to be important for supporting the implementation of these innovative pedagogies.

Some Challenges We All Face
• STEM Education (Henriksen, Dillon, & Ryder, 2015)
• “Closer cooperation with the Science and Technology Studies could assist in
identifying more adequate forms how to communicate scientific knowledge
and how to engage children into the attractive and actual scientific
research.” Conference Welcome Message
• Teach “21st century skills” AND curriculum content
(Danah, Punya, & Petra, 2016; Fullan & Langworthy, 2014; Voogt & Roblin,
2012)
• Innovative pedagogies in a didactic classroom (Fullan & Langworthy 2014)
• Mainstreaming “boutique” interventions at SCALE (Griffiths & Goddard
2015)
• Teacher beliefs (Ertmer 2005)

Teacher Quotes
• It was very much 90% they were working, 10% me!
• They’re a bit more excited I think which is nice, there is no them versus us in the class they can
see that they can actually just teach themselves now.
• The other thing I'd say which I think is really important, from my point of view, is the kids
taught me a lot
• “(The postgraduate certificate) made me do something I had wanted to do for a long time but
wasn’t confident to do...the fact I was being graded made me build the website and
incorporate it into my classes...I am happy now as I have it done”

Student Quotes – Open Coding
• “Yeah like I think the project was good at making us be creative and
critically think about the design and structure of our bridges,
sometimes in Maths we don’t get to be creative and innovative in
Maths and it’s hard to reflect on our answers because we cannot
check to see if they are right or wrong.”
(B21 – Plan-create-reflect)
• “Yeah it was cool that you could learn from your mistakes and
change your design, it kind of helped you and you could work out by
analysing the load test and testing your bridge”.
(B21 – Plan-create-reflect)
• “It was fun I enjoyed the learning experience, you gave us a lot
more control and we could make our own decisions, and you (the
teacher) kind of let us work out the problems for ourselves which was
good because we learned more by doing it ourselves.”
(B21 - Student responsibility for learning)

Student Quotes – Open Coding
“I thought they were beneficial, they were like really good and kind made
you think about math in different ways.” (Attitude)
“It was more interesting and I found that I looked forward more to
coming to maths.” (Attitude)
“I thought it was helpful because you got to see like every time you
changed a number and like something would happen on the screen and
you'd see something and that helped.” (Technology – Constructionism)
“Helpful because you had to work a few times at finding the numbers
you needed for the graph.” (Technology – Constructionism)

Take Away Message
1. In the Irish context the policy framework is conducive and we are
making some progress in addressing the issues outlined earlier.
2. The Bridge21 model is one suitable framework for developing
constructionist STEM activities for an authentic classroom setting.
3. The CPD empowered teachers to develop the activities and research
their own practice.
4. Teachers are persuaded most by other teachers.
