In sessions, concepts are explained clearly if there is a need. Otherwise, practice is the focus. Active learning is best in any subject. Material and concepts are presented after a relevant practical problem is chosen. Then the required knowledge and problem solving approach and methods are presented. Teaching strategy in test taking is beneficial to many students. Teaching error-free programming techniques is valuable in CS. The approach to physics and math problems should also be an error-free one. In all technical subjects, problem solving should be accomplished in small steps, checking the consequences of each before proceeding.

I want to help students learn problematic material. Beating fear of success is possible through sustained small successes. The only real teaching/tutoring goal is to teach a student everything the teacher/tutor knows so that the teacher/tutor is no longer necessary.

Online tutoring has been very successful due to screen sharing. With that, both the student and the teacher can share their entire desktop, although not simultaneously. Control of the other's desktop is also possible, which allows the possibilty of assistance that is close to 1-1 tutoring. The use of tablets and a stylus make it possible to provide legible and clear presentations of math and figures for technical courses - even CS courses. Notes made with a tablet and stylus can be saved to a pdf file of one page with certain pdf software packages. The chat in my zoom now allows the sharing of fairly large files (larger than that allowed by gmail). That allows google drive to be by-passed.

Sessions are online only and by appointment only. My Zoom is utilized for sessions. Lesson notes are displayed and later saved to a pdf file for students, if applicable. A tablet and stylus are used for clearer notes. Students may use the whiteboard of My Zoom or MS oneNote if available. Notes can be written with a mouse if no tablet is available.

I have a past total of about 4 years of part-time tutoring experience in St. Louis, MO for a private company and, in Edwardsville, IL for SIUE. I have additionally about 1.5 years of part-time and periodically full-time experience (2016 - 2017) with online or primarily online tutoring employers. I began this tutoring business in June, 2017, which has been a full-time job.

I am a former part-time software engineering consultant using C++ for a US industry in PA (2019). Also, in industry, I have 6 years of experience as a programmer/software engineer. I have 12 years of programming experience in my scientific research at Wash U School of Medicine in St. Louis. Through my dissertation and postdoc, I have 5 years of FORTRAN programming experience. At Wash U School of Medicine, I have 8 years of part-time UNIX system administrator experience.

Physics Tutoring

Mathematics Tutoring

General Tutoring: Research help; Students of all ages welcome.

I am also open to helping with research projects, theses, or dissertations in any field (especially HRV) requiring math, statistics, physics, programming, and certain areas of engineering, if there is a good fit.

Students of all ages are welcome. I have had C programming students as young as 10 and 14. In java (AP CS), I have tutored 8th grade, 9th grade and HS students, and several HS AP Physics students. I have had a 12th grader learning Java enterprise apps (then moved to C# .Net web forms). I have had one 8th grader and two 9th graders in advanced math classes. I have tutored math, physical science, and astronomy for a student in 7th grade. I have taught a 7th grader physics with a portion of Hewitt’s Conceptual Physics (slowly). I have had students in research, students working on their Ph.D. dissertation, students working on their MS thesis, and students working on their MS or MBA, as well as elementary students, HS students, and undergraduates in CS (mostly) or engineering. I have also helped an industrial research professional Ph.D. with C and C++. Lately I have been getting more MS students working on CS-related degrees.
