ジョンズ・ホプキンズ大学(Johns Hopkins University) による The Data Scientist’s Toolbox の受講者のレビューおよびフィードバック



In this course you will get an introduction to the main tools and ideas in the data scientist's toolbox. The course gives an overview of the data, questions, and tools that data analysts and data scientists work with. There are two components to this course. The first is a conceptual introduction to the ideas behind turning data into actionable knowledge. The second is a practical introduction to the tools that will be used in the program like version control, markdown, git, GitHub, R, and RStudio....

It was really insightful, coming from knowing almost nothing about statistics or experimental design, it was easy to understand while not feeling shallow. Just the right amount of information density.

This course was a good intro especially in setting all the necessary software for future courses. I suggest to read the manuals, books and other readings the profs suggest. The resources are helpful.

This course was a loss of time and money. Except from week 3 material, the rest can be found on the internet and should be required by everyone who wants to take that specialization. This course doesn't worth it, it's just to take extra money from anyone who wants to learn about Data Science.

This should not be a course in itself

Poorly organized. Poorly communicated. No reliable source of assistance with technical problems.

It's a course which is designed to preview the other courses. It could easily be eliminated

Not worth the price. Extremely basic stuff spread very thin over too much time just to be able to charge for it.

Very bad course so far. Very little detail and Assignments are very hard to solve. Worst $500 dollars spent in my life, and the course isn't worth even $10!

I'm an online instructor myself and the quality of the course isn't worth its price!

Not useful at all if it's audited.

By far to expansive for what you get. Anyway, thanks for the hint about swirl.

Quizzes were based off of extremely high level overview videos not covering anything specifically or deep diving into anything. When applying the git commands covered, numerous errors arose. Overwhelmingly academic course with very little hands on. This is not for anyone actually looking to work in this field, but for someone looking to be able to talk about this field.

$38 is a lot to pay for tutorials about how to install software. This course takes only 20 minutes to complete. It is also obsessed with command line interfaces. There's a reason that they were left behind in the 80s. It does cover GUI software like Rstudio, which is ignored for the rest of the course. How about something on the desktop Github version? So much easier to use.

They charge you to take a class that explains how to install a few programs. If you go to the program's websites, there is directions to install it anyway, so this was completely unnecessary. Waste of money. This class should give you some early training on R before throwing it at you in the next course without enough training.

I have no idea why you called it course, since there was nothing inside.

Worthless course. There should have been no need for this course and the fact that they charge money for this is disappointing. This module could have been easily merged with the next module (R- Programming). Just a few pages with instructions on how to install the required softwares and repositories would have sufficed.

I missed the entire course deadline just because I stuck in one of week 4 projects - pushing a file into GitHub. When I went to the forum, there are so many people in the same situation. The main reason is that the week 4 video did not cover the project content well. Overall, compared to other programming courses I took on Coursera, this course is not well organized at all! Instructors basically just read words in slides, no interesting examples and no hands-on practices, especially week 4 slides that look like a syntax reference document. So the entire instruction is very boring, making me wonder why I need to sit here and listen to word reading rather than buying a textbook. Also, people coming here to learn it are new learners. When the instruction skipped much and made the content not logical and complete, it is very difficult for us to understand what the video is talking about. That's why in forum there are so many people expressing their confusions. This entire specialization is the one that I've taken and feel the worst (I got lost in the R course too). I strongly recommend the instructors of this course watch and learn how the instructor of the specialization "Python for Everyone" organizes and teaches the content. He makes programming become very interesting and easy to understand. He also provides many hand-on practices to help learners understand abstract concepts. Unfortunately this specialization instruction is just about reading words in the boring slides.....

Eu achei o site desorganizado, não sei se concluí ou não o curso. Não sei se executei todas as tarefas ou não. Decepcionante

Certainly not worth paying for this course, only talks about how to install the tools.

Not able to take quizzes when you try to take the course for free.

Is this a real course for a data scientist just installing shit and a peer reviewing for that screenshot and forking all repos ...very bad not worth to be with rest course in specialization

Not really enough content to be a course in it's own right, should be additional material as is useful, but definitely not a requirement.

by Louise S

Mar 01, 2017

A simple list of programs that needed to be installed would cover 90% of the course content. Some of this content is also repeated in other courses in the sequence. If you have any technical skills this entire course is extremely tedious.
