 Hello, my name is Sophia and I'm an undergraduate Business Economics student here at UCLA. One of my most significant learning experiences happened in high school in my senior year calculus class. Instead of lecturing at us every day, my teacher, Mr. Cohen, had us sit in tables of four and we would spend the majority of class working on these worksheets called quickies. The structure of each of the quickies allowed us to build on previous knowledge, with the first few questions reviewing old concepts and the following ones guiding us through learning a new calculus concept. As we worked through these quickies, Mr. Cohen would walk around the room carrying a stool, stopping and sitting down at tables that needed guidance. At the end of class, he would choose a few tables to present their work to everyone. Mr. Cohen's focus on active learning and student collaboration are what made this class really impactful for me.
