Learner Reviews & Feedback for Developing Data Products by Johns Hopkins University

excellent

This is my comment as a beta tester:

1) The changes to the lessons have changed the course for the better.

2) If you want to be factually right than the statement that Bootstrap is a style should be changed on a few places. Bootstrap itself is not a style, although it is used as a style guide for the development of products. Obviously this is not a big issue and people that delve into will find the facts easily.

Bootstrap is an HTML, CSS, and JS front-end framework with a strong support for themes which people also call styles. Many themes/styles are available to build responsive, mobile-first web sites. Bootstrap was created by a designer and a developer at Twitter in mid-2010 and was released to the public in August 2011. It has become one of the most popular front-end frameworks and open source projects in the world. Bootstrap has a few easy ways to quickly get started, each one appealing to a different skill level and use case.

Brian Caffo is the best! No one could explain better than him. Congratulations for this excellent course, you are my inspiration to become a better data scientist.

Excellent Course!

Very good for anyone wanting to get into the field of Data Science using R

very interesting and useful for R programmers

Fun making some apps and presentations in the context of Data Science.

For me the course was really interesting. Yes, all topics are not covered in deep details - but lecturers show what technologies exist and for what purposes. So if you're interested in some of them - it is up to you to discover more (useful links are included). Really nice and useful overview.

Nice I like a lot, shiny nice tools. thanks to the teachers.

I loved it, very interesting and interactive

awesome course

Excellent course, that helped me finish my own student project.

Really enjoyed learning how to build a Shiny App, and see a lot of use for this in my work environment. The Slidify product was not as useful - after 3 months of working on the project, I moved from Slidify to RPres, and was able to complete the project in very little time.

Awesome Course and content

Was a highly pleasurable and rewarding experience for me.

Now, i'm analytical thinking

Nice course

Fantastic!

Filled with useful information about practical tools.

Love it!

One of the best

interesting course covering plotly, r markdown and shiny. love it

The new platform is very versatile and easy to navigate. The page layout is much more clear. It is easy to navigate from course material to discussion boards.

I like the Quiz format, including expanding the number of choices for the multiple choice selections, but the grading was confusing. For Quiz 3, some questions came back with multiple "Well Done" comments, even when I had not selected the answer for which I was being praised. I also was told I made errors on the same question.... and this was after I answered the question (Question 2, on R generic functions) the exact same as I had answered it when I took the course earlier this year.

I was not a fan of not having to take a picture to submit work, so I am pleased that is no longer a requirement. I hope the typing pattern match is sufficient to affirm identity.

I have one comment on content specific to this class. Week 3 content lacks relevancy to the project and data products in general. I agree that knowledge of R packages, classes, and methods is an important part of understanding R. I am not sure where that fits in the Data Science curriculum as a whole, though. Maybe expanding the curriculum to include a second, more advanced R class, with a project to write our own methods, build an R package, or do something with yhat. That would assign relevant work to reinforce the lectures.

I would be happy to do further beta testing.

This is a great introduction to some of the many ways to present your data. It's probably the easiest course in the specialisation but shows off an impressive array of widgets and gadgets.

This Course was georgeous!!, i like the way of share my analisis, shiny rules!
