  2. remove the finished courses from "My Courses"

    It's very difficult to see which courses I completed, since there is no indication other than "started" . The courses should be presented in different categories ("not started" , "started" , "completed" )

  3. Option to download as "PPT" slides

    An option to download resources in PPT format, would benefit the students to go through the course content easily.

  7. update the course material

    Some of the commands listed in the lab is outdated and deprecated, I'd suggest review the content often and update it. Or at least put reference documentation in the course description so new learners can refer to up to date documentation. I'm available to discuss this further or help out.

  8. review the answers with the students to the final exams after submission

    Dear Whom-ever-is-responsible

    While I passed the map-reduce/YARN course, it would be really useful to get feedback on the answers I got wrong on the final. I understand that if there are a limited amount of potential questions, you don't want a free copy of all answer floating around the net. Unfortunately, at the moment I am unsure if I got a question incorrect because of actually not knowing the proper answer, or due to lack of clarity in the question (which was apparent for several)/misinterpretation.

    Just FYI

  10. Hadoop 101 course

    The course has good content, but the instructor is just reading the lines instead of trying to explain them meaningfully. It definitely needs improvement. Please look into it.

    Thanks.

  15. Send an email alert once a course becomes available.

    I would like to pre-enroll to a course that is not available yet (Text Analytics) and to get an email alert once the course becomes available. Alternatively I would also appreciate to have the option to "subscribe" to a learning path and if that learning path is updated with additional courses then I would get an email alert.

    I really appreciate the Cognitive Class platform and I don't want to miss an interesting introduction to text analytics.

  16. re-publish Hadoop 101 with a better narrator

    Just a comment to say that the narrator for these courses is in a hurry, and slurs the words, and does not annunciate. It seems that the best way to review these topics is to listen once, then go back and re-read the text that is associated with the material. Also, when I try to slow down the voice, it does not seem to take to .75 .. I have to change it to .5 and then change it again to .75 .

  17. Suggestions Webpage View

    I would suggest to adjust the layout of the webpage to include completion state of a course right from the overview list of courses I have applied for. Right now, I need to enter each course and click 'Progress' for each of them to find out whether anything is missing. Also, move the completed course into another view or section so that the screen only shows courses I am most likely still working on. Also, from the overview page, time required should be visible as well right in the overview. I would further suggest to slice course into more manageable…

  19. Big Mistake

    In video "ANOVA" at 3:51 there is a big mistake in my opinion because

    pvalue=1.0586193512077862e-11 not shown and the narrator said it is greater than 0.05 and this destroy the logic of the video.

    Kindly fix it fast.
