STREAM Lab

The Mater Dei Catholic School STREAM Lab is based on the “Maker Movement.” The “Maker Movement” is designed to allow a student-centered approach in the areas of Science, Technology, Religion, Engineering, Art, and Mathematics.

The STREAM Lab allows for students to flourish in an environment where they tinker, create, invent, build, and interact with each other within the curriculum. Students will build confidence in their capabilities and explore the world they live in to develop an attitude to fix, make, change, modify, and customize their world.

I am a product of 18 years of Catholic education.  I attended St. Louis Elementary School in Yeadon, Delaware County.  I completed my high school education at Villa Maria Academy in Malvern. Immaculata College was the school where I received a Bachelor’s degree.  My graduate work was completed at Villanova University.  I worked in the pharmaceutical field doing kidney research for seven years before starting a family.  I have been the comptroller of a small company for the past 48 years. I am the proud parent of 4 children – 2 boys and 2 girls.  I started at St. Stanislaus as the first computer teacher.  I taught 2 programming languages for 3 years.  Then I moved into the eighth grade. During the first 5 years of Mater Dei I taught in the 7th and 8th grades. This, the eighth year of Mater Dei,  will be my third year as the coordinator of the activities in the Stream and Science labs for grades 1 through 8.
