As a high school math teacher, I have created numerous slideshow presentations for my math classes, allowing me to give the students my full attention. This has saved me tremendous amount of time and has helped students when they are taking notes. Instead of having to hurry and copy their notes before I erase it from the board, at the end of the presentation I can go back and show the slides for those students who have difficulty writing their notes quickly.
The slideshows demand time and technical know-how for it to be useful in the classroom. I have noticed that my “keynote” presentations are growing bigger and my lesson preparation has lessened. Because of the substantial amount of time I have saved and the effectiveness I have achieved, I have decided to share my presentation with the world. My hopes are to lessen the preparation time of math teachers around the world and allow them to find more time to enjoy their after-school hours.
Prior to coming to the United States, I have taught in several schools in China and the Philippines. I have been teaching math since 2005 in Barstow High School and have taught almost every subject since. I have taught strategic math, algebra1, algebra2, precalculus, geometry, and AP statistics.
For two years I was assigned as the math teacher for a particular group of students, also known as House E. I learned a great many things about teaching from those magnificent students and they have helped me better my teaching ability. The presentations I am offering to you now is a product of my effort to try and help the students of House E better learn and understand math.
Teaching was never my first choice of career. I used to be a project manager in an IT firm but the teaching bug bit me. As the saying goes, “Many are called, but few are chosen”, and I believe I am one of those chosen few who truly enjoy the job of being a teacher. Teaching has broaden my horizons and taken me to so many amazing places where I met so many wonderful people.
