Amazing Teaching Moment

My amazing teaching moment was when I conducted a professional development lesson with K-8 teachers on light reflection. Teachers had to use the Design Cycle to design and create a periscope using mirrors, tape and paper towel rolls to try to see an object behind a wall. The objective was to gain an understanding of the Design Cycle just as engineers do when they design and create things and to understand how light reflection allows us to see images.

Utilizing the 5e model (engage, explore, explain, extend, evaluate), I began the lesson with two engaging activities where teachers had to consider the best window covering for seeing inside a room. They also had to look at various items under different lighting conditions and think about what they need to see – light! Then teachers had to explore various ways people see things that are hidden, such as submarines using periscopes. Teachers then used the Design Cycle to imagine and plan ways to create a periscope to view a hidden item in the classroom.

The lesson focused on higher order thinking questions to help teachers and students develop thoughtful problem solving solutions and ideas. Questions, such as how can this knowledge apply to real life situations? What are some assessment considerations? How can students share their results with others?

Afterwards, teachers reflected on the lesson using prompts for discussion of how the lesson could benefit student learning. It is important for teachers to understand the design cycle process as they teach students how to become effective 21st century learners. The Design Cycle includes: imagining solutions to a problem, choosing the best solution, creating a plan, designing a prototype, testing the prototype, making improvements if needed, and sharing results. In order for students to be effective in the 21st Century, they need to be able to practice and understand the process of creating and problem solving that real engineers experience.
