ジョンズ・ホプキンズ大学(Johns Hopkins University) による データサイエンスのクラッシュコース の受講者のレビューおよびフィードバック



By now you have definitely heard about data science and big data. In this one-week class, we will provide a crash course in what these terms mean and how they play a role in successful organizations. This class is for anyone who wants to learn what all the data science action is about, including those who will eventually need to manage data scientists. The goal is to get you up to speed as quickly as possible on data science without all the fluff. We've designed this course to be as convenient as possible without sacrificing any of the essentials. This is a focused course designed to rapidly get you up to speed on the field of data science. Our goal was to make this as convenient as possible for you without sacrificing any essential content. We've left the technical information aside so that you can focus on managing your team and moving it forward. After completing this course you will know. 1. How to describe the role data science plays in various contexts 2. How statistics, machine learning, and software engineering play a role in data science 3. How to describe the structure of a data science project 4. Know the key terms and tools used by data scientists 5. How to identify a successful and an unsuccessful data science project 3. The role of a data science manager Course cover image by r2hox. Creative Commons BY-SA:

Well taught





This is a great starter course for data science. My learning assessment is usually how well I can teach it to someone else. I know I have a better understanding now, than I did when I started.



Is really hard to summarize the potential of Data Science and being clear, but I think that the instructors have done their best, so that we can achieve the most from the Course.\n\nGreat Job!

Was a very broad review than was expecting.Content covered is too less

by Hussain, C


Very general course. Doesn't give much insight into data science.

by Deepak G


Very short. Quality of the course is also not that good.

by Diego V


too much lingo and words without clear definition.

by Eduardo R L


1-week does not seem enough for a Crash Course

by Shafeeq I


Not that engaging content. bit lengthy

by Carlos C


This course is too short.

by Yousuf B


Overly academic

Very shallow

Quite disappointed. While I expected a high-level summary, anybody who has done basic stats in school probably knows 90% of the superficial level of information in this course. Buzzwords like "neural networks" and "random forests" appear during the course, but without even a high-level explanation of what those are. The lectures are pretty low-quality in terms of content and presentation. The most informative portion would the comparison of Machine Learning to Traditional Stats. The quizzes are pretty simple (with some common sense you could probably pass a lot of them without going through the content of the course). Completed the course in one sitting, in about a third of the time estimated on the enrollment page.

There is an error in a question in one quiz. I have tried selecting each answer multiple times, and the response still comes up wrong. This is preventing me from completing the course, and the certificate, which I need to complete for work.

by Edem N


The course, though fascinating, the only setback is the certification does not approve the learner being taught from JHU or certification being authentic which is per the information it conveys.

No incentive therefore continuing with it.

by Alessandro V


It's too short, I think it should be a part of a course and not a course itself.

It is a repetition of concepts and examples from other courses by john hopkins univ.

by Dannie L T Y


I struggled thru. Barely. This is no joke. Course description should state that minimum knowledge should have some statistic background or something like that.

by Tamer D


It would be great if slides were prepared and used through out the videos....

I was looking for something a little but more technical...

by Ismail H D


This course is very sparse on details, and just a week of content. The lecturer is not the best at explaining concepts.

by Guy B


Very basic, for absolute beginners/ managers completely new to data (let alone data science)

by Carol P


Too short to get any depth of information. Too expensive for the content provided.

by Poon F


No much information presented. Disappointed that this comes from John Hopkins.

by James T


Un-reliable platform. Make screen shots of all completed quizzes

by Cheng-Jiun M


it's a shame to split a one month course to four.

by Caio S


Quiz should be open to all students... :/

by Michael W


Only one week. Not much depth.
