My name is Harold and I have tutored 500+ students in science, technology, engineering, and math (STEM) over the past 30+ years. I have logged over 3,000 tutoring hours mostly through Wyzant. I worked in the BYU Math Lab to pay my way through college where I earned my MS Electrical and Computer Engineering with a minor in mathematics and aerospace studies. I am currently attending online college working towards my Ph.D. in Mathematics.
I tutor all levels of math to both high school and undergraduate college students. This includes all of the subjects in the table below.
I love teaching students that really want to learn and have set a goal, but are either behind or are not connecting with their teachers. Math can be easy and fun when you understand the key concepts and basic building blocks. My Socratic teaching style is to ask my students focused questions that cause them to think, then determine the correct answers for themselves. I then like to show multiple ways to solve the same problem and how to verify the answer as being correct. This is the difference between a 'B' student and an 'A' student. I also believe in teaching how the covered math concepts apply to our everyday lives.
In addition to STEM, I also tutor C/C++, Java, Python, Chess, Cybersecurity, and the Microsoft Office Suite. Back in 1986 I published a book and software package used by several universities on numerical analysis using the C programming language.
I am setup for remote tutoring using the Wyzant Online Tutoring Tool and Zoom. I work with Wyzant as a part-time independent contractor to find new students to teach.
