While this course did provide some valuable introductions to data visualization and presentation, on the whole it suffered greatly from one of the same problems that has plagued this whole certificate program: bad questions on the quizzes. Many of the quizzes used questions or details that were barely covered in the videos and readings, or were certainly not emphasized to the degree that they should have been if they were important points to be remembered (as a quiz should be testing a student on). It seemed as if someone unfamiliar with the course material went through the video transcriptions and pulled out random lines, then created questions based on those fragments of text.
Additionally, while not being a specific fault of this course but more of depersonalized online learning as a whole, many of the topics in this course are not suitable for answering in a multiple-choice or multiple-answer format. Instead, they should be handled as graded free-response—but that would require teaching manpower that simply isn't available.
I have to add that, while Kevin Hartman is undoubtedly a fantastic data analyst (or else he wouldn't be Head of Analytics at Google), he is not a good teacher of the material. He did not seem to have a good grasp of what a student who is completely new to the material would need to know, and in what order. He presented a lot of great ideas and gave many resources, but without much guidance in how to process those resources and use them actively for creating data visualizations or presentations. He also skipped around a lot and did not fully explain what he was doing in numerous videos, such that someone else had to come in later and add notes during the videos to explain where Kevin had gone off to in order for the student to follow along.
All told, this course had some value, but rather less than most of the others. Some of that has to do with the inherently more subjective nature of data visualization and presentation, as opposed to previous courses in this certificate program which were based on more concrete and objective topics. However, I do think that the course could have been significantly better.
(As a final side note, I was a little weirded out by Kevin's consistent fanboying over "the McCandless Method". Some other perspectives might have been nice to have alongside that.)
