Office Hours, Spring 2017

8:30 AM – 5:00 PM weekdays, except for classes, lunch, meetings, etc.
Meet me in person or via phone, chat, Skype, etc.
I "chat" via Microsoft Skype for Business.
    (Skype for Business may already be installed on your computer as part of MS Office.)
I talk on the telephone too! x6245 (I like the telephone. Call all you want.)

Students have permission to call or contact me at my office at any time, 24/7, but you may need to leave a message if I'm not in.
Students also have permission to telephone me at home between 8 AM and 10 PM (except not about course work on Sunday please). My office phone number is 712-722-6245. My home phone number is 712-

I have a "virtual open door" policy. Any time I am in my office, I'd like to be available. Unless there is a "do not disturb" note on my office door, just knock—even if the door is physically closed. Similarly, if you are in a dorm or elsewhere and want to talk, just pick up your phone and call.

Dordt College asks me to publish "official" office hours. They are Mondays, Wednesdays, and Fridays at 10:00 AM to 11:30 AM and Thursdays from 2:00 PM to 4:00 PM. You are welcome to use them but you are equally welcome to visit me outside the "official" hours too. In fact, I prefer that you have your questions answered as soon as possible, so use my "virtual open door" whenever needed.

Here is Prof. De Boer's general >Weekly Schedule.


In the Spring of 2017 I am teaching these courses:

C EGR 220/PHYS 206  Linear Ciruits and Electronics (including a lab)

C EGR 323  Electronics II
Note 1: Professor De Boer welcomes qualified students to inquire about adding a Kuyper Scholar's Project to any of his courses.

Note 2: Students may click on the blue "C" symbols for direct links to the course files in Dordt's course management system, called "Canvas." Anyone may click on the gold links to the public portal for the course.

Some of the courses that I have taught in the recent past are:

EGR 322  Electronics I (with a lab) *
EGR 360  Introduction to Power System Analysis *
EGR 363  Introduction to Communication Systems *
MATH 204  Differential Equations *
* Links to Prof. De Boer's most recent past web site for the course.
From there you can find a link to the course syllabus and more.
