Doc Dos Math & CS

Some matrix algebra problems used for my Precalculus Honors class, covering Matrix multiplicationMatrix inversionMatrix solutionsThe puzzle is a substitution cypher/cryptogram where each original letter in the phrase was replaced with another (an perturbation of the alphabet). There are not 26 problems, thus the students will still have to use some basic logic to solve the puzzle. Many students recognize the phrase quickly and finish within an hour.

Experience

I was an associate professor of mathematics and computer science for 13 years at a small university before moving to my current position as a high school teacher at an independent high school.

Teaching style

For the past five to six years, I have incorporated puzzle-style activities into my mathematics curriculum. My belief is that fostering students' analytical thinking is crucial, and I have observed that these puzzles provide an enjoyable challenge for them. In fact, some students view these puzzles as a rewarding experience after completing the mathematical components of our lessons. In my computer science courses, I often have the privilege of teaching exceptional students. To accommodate a range of abilities, I design labs and projects that are achievable for the average student, occasionally with some guidance. However, these assignments are structured with enough complexity to ensure that even my most advanced students do not find them trivial and remain engaged.
