Four years ago, Dr. Peter Esperenza sought to do something special with his high school math class. His objective was twofold: make math lessons (1) more potent and (2) widely accessible. Moreover, he wanted to flip the classroom so that instruction could occur at a self-regulated pace in the comfort of one’s own home, allowing for more in-class activities and hands on exposure to the material being covered.

If you are unfamiliar with the term “Flipped Classroom,” it can be summarily described as follows (courtesy of www.numberbender.com): “A flipped classroom is one in which students watch and complete online lectures on the subject matter at home, and use their classroom time to work on problem sets with the help of their teacher and classmates.” It is a trend in education that is gaining unbelievable momentum, especially in the area of science and mathematics. As Philadelphia based teacher Mary Beth Hertz explains, flipped classroom environments allow students to “move at their own pace, review what they need when they need to, [and] catch up on missed lessons easily through the use of video and online course tools.”

As Dr. Esperenza began sharing his self-made videos with his class, he realized that a large repository was needed for his massive library of lectures. YouTube was the perfect home, as it not only had the capacity, but it was completely free. And so began Dr. Esperenza’s journey to upload hundreds upon hundreds of video lectures relating to algebra, trigonometry, and calculus. Some of his most notable online lectures include Laws of Exponents, Evaluating Ratio and Proportion, and Introduction to Conic Sections.  His tutorials employ the use of a physical whiteboard, clean and multicolored illustrations, and concise explanations. The clarity of his explanations is precisely why he has been able to garner over 800,000 views and 7,000 subscribers since the inception of the channel.

While the majority of the lectures are presented in English for his students at Barstow High School, Dr. Esperenza wanted to help folks in his native country of the Philippines. As such, he began to create math tutorial videos in his native tongue. The response has been overwhelming. A wave of students from the Philippines have recently subscribed to his fast growing channel to soak up all of the amazing information provided. As Dr. Esperenza noted, there are not many options for solid math explanations in the Filipino language.

Dr. Esperenza is not only a teacher, professor, and YouTuber, but he is also an author. In early 2016, he published The Power of the Flipped Classroom, a multi-touch book that explains the process of flipping a classroom. He has also published three academic papers on the effects of successful implementation of a flipped classroom. He not only describes the process, but he also sheds light on the positive outcomes achieved measured via grading statistics.
