STAMFORD — Each year, Ireland celebrates “maths week,” which promotes arithmetic activities across the country from schools to pubs.

Carrie Chiapetta, former director for math and science at Stamford schools, was inspired by this initiative while on a trip to Ireland and has expanded the concept to include science, technology, engineering and math to form STEMfest.

The daylong free festival was scheduled to return for a fifth year on Saturday, but the forecast for rain has postponed the event — featuring activities celebrating science, technology, engineering, art and math — to the fall.

“It encourages all kids that they can and should pursue STEM learning in their future, regardless if they wind up in a STEM career,” said Jim Forde, STEMfest co-chairman and Scofield Magnet Middle School administrative intern. “It provides the kind of computational thinking and problem-solving abilities that are applicable across discipline and makes them better thinkers in general.”

Stamford schools have been celebrating STEAM Week with activities in and outside the classroom.

Part of the goal of STEMfest is to exhibit how students in Stamford Public Schools are learning STEM in their classes. The activities and exhibits are presented by student, parent, teacher and community volunteers.

“It’s always been community-based, but there’s a larger percentage of presenters who are right from Stamford Public Schools which is exciting to me,” said Beth Eiseman, STEMfest co-chairwoman and curriculum associate for science. “Part of the purpose of this in my mind is to take the practice we do every day and make it public. It does help (the public) get a view into how we teach STEM every day in our schools.”
