I decided to take Google’s Technical Support Fundamentals course online via Coursera because I wanted to encourage another close friend to finish this course. I’m at the end of week 4 and up to this point the content was very good. But as everyone knows, there’s nothing more frustrating than taking a multiple choice quiz when some of the answers on the quiz are wrong. Please Google Developers, Coursera, and Design@Coursera fix these questions.

Please review the “History of the Internet” video in “The Internet” module for a refresher.
I’ve ran into even more troublesome questions since these initial ones were found. This to me is a very disturbing trend. When a learner is trying to master a subject they need to have the same concepts that were taught consistently reinforced. Unfortunately Google has chosen to take some other path. Below I present an example of negative reinforcement where the quiz question contradicts the instructions previously received by the course:
In the section, “Start with the Quickest Step First” we are instructed to do the following:
Here’s where the Start-with-the- quickest-step-first method comes into play. We want to get to a root cause effectively. But sometimes, there are multiple options we can use to isolate something. So how do we know which option to try first? It’s pretty simple. Try whatever’s fastest first.
And yet when we put this advice into practice in the quiz the learner is penalized. This is a negative learning reinforcement that teaches the learner that what matters most is NOT putting into practice what they learned. What matters most is finding the “answer” that was in the mind of the creator of the test. This is a very harmful practice that has many unintended negative consequences for new learners who are trying to grasp new subject matter.
Obviously the Start-with-the- quickest-step-first method would lead one to believe that checking to see if the caps lock is on would be the step that would require the least amount of time to check. By telling the student that this answer is “incorrect” they are punishing the student for putting into practice what they learned. The student learns instead that when they are taking a quiz the “correct” answer is whatever answer was in the mind of the instructor when they wrote the test. This can have some harmful side effects in that it contradicts rather than enforces what the student just attempted to learn.
Continuing my evaluation of the course
I will continue to document the issues I am finding with this course but so far it’s not looking very good. Google really needs to have experts review these questions to see what impact they are having on learners so that they don’t inadvertently cause harm to students who are attempting to put into practice what they were taught.
