  1. dynamics and modulation

    My general observation is on the voice overs reading the script., It sounds too mechanical, a subject matter expert when teaching will modulate concepts better, in a way students can remember by remembering their voice or dynamics. The voice that is reading the transcripts lacks dynamics and the human element. Its too mechanical. Can be improved for better.

  2. Change the 'what is hadoop' section

    The sound quality and speed of speech is really bad. I am from the UK and I have found this really difficult to understand. I wasn't able to make out half of what was actually being said.

  3. Rework Graded Review and Exam Questions

    I liked the course, but was very disappointed by the way the Review and Exam questions were compiled.
    To me it seems the questions were not created by an SME but simply put together based on the course text and therefore have no benefit for learning and understanding.
    This also causes questions that also have correct answers being marked incorrect (example : When importing Excel spread sheets only the first sheet is being imported. True or False?
    The actual correct answer would be False because Watson is prompting You to choose which sheet to import, it is not only importing…

  4. Correct all bad grammar

    It is so disappointing to see the use of bad English grammar on your site as it degrades your message. It doesn't matter whether you have 'copied' someone's blog or written it yourself. Bad grammar does not further any learning - it stops it.

  5. correct subtitles on Open source Tools - Creating an account video

    On the video "Data Science Hands on with Open source Tools - Creating an account" the captions do not line up with the audio. The transcript contains the text:
    To change your profile settings, toggle the account button on the bottom left corner. Change your settings and click Save.
    This does not occur in the audio of the video.

  7. Rewrite and restructure all courses under the guidance of an educator.

    I am new to Data Science and I have taken the DS Fundamentals course and am 4/5ths through DS for Business. The course structure, language, and materials are abysmal. Fundamentals need to be explained in layman's terms, not jargon. Make videos that actually illustrate the course text, not just parrot it with a useless graphic.The math operations used in R need their own course. And get the module sequencing correct, so students don't have to hunt down materials (and then load the same ones repeatedly). Furthermore, I think the quizzes and tests should go more in depth on the subject…

  9. To update your mobile webpage

    The buttons on your mobile webpage are not displayed correctly. They don't adjust to the screen size and thus are too long.

  15. verification of answers

    For the review questions , rather than having a 'check -reset-final check', I think it will be more intuitive and computationally more efficient to have a conditional submission. I.E In the first attempt If a check results in a correct answer, the submission should auto-lock it self. That way you will not have to reset and then again perform a final check because we have already got the answer in the first attempt.

  18. two answers showing correct answer, and other suggestions

    On Q.13 of Spark overview for scala analytics, both 'group by ' and 'all of the above' is showing the answer as correct. it is supposed to be a single correct answer question. Please correct it.
    second, kindly make arrangements so that there is no check-reset-check-reset-check-reset-final check loop!!
    It would make more sense to save and evaluate the answer when the option is clicked.
    This exam had 20 question, for each question the number of steps are :,
    1.click option of choice
    2.click check
    3.click reset
    4.click option
    5.click check
    6.click reset
    7. click option
    8.click final check

    That's 8…

  19. Instructor Voice in Hadoop 101

    It will be really helpful if the voice of the instructor can be changed. The instructors speed and pronunciations was too much to understand. With only good intentions i request the administrator to make the necessary changes to help students.

  20. User Interface

    When one clicks on the username, a list of enrolled courses are listed. I would suggest the team to categorize the courses as enrolled, In Progress and completed. This makes the UI more user-friendly and the user can easily keep a track of the status of his/her courses
