teaching

Teaching Assistant in CS 31 (Intro To Computer Science)

Undergraduate lower division course discussion, UCLA Computer Science Department, 2020

As a teaching assistant, I taught programming principles in C++ to students with little or no experience by revisiting lecture material and going over practice problems. Material ranges from if-conditions and loops to 1D pointer arithmetic.

Dates: 2020-03-25 through 2020-06-12

Teaching Assistant in CS 130 (Software Engineering)

Undergraduate upper division course discussion, UCLA Computer Science Department, 2020

As a teaching assistant, I taught software engineering principles in Java to experienced students by revisiting lecture material and going over practice problems. I also graded students’ app design projects based on their adherence to these software engineering principles. Material ranges from UML diagrams and design patterns to software testing.
