學生對 约翰霍普金斯大学 提供的 数据产品开发 的評價和反饋

very helpful and teaching. learning practical tools for producting data products. examples in the course are not very complex, but give a very good intro for several tools.

Course content was helpful. Some confusion in assignment questions not aligning with what was covered in lectures where it would have helped to clarify that was intentional.

this curious course teaches about tools and techniques for communication with audiences on data science. some tools are very interesting and deserve a deep research from the learner, this course is mostly informative about the potential of such tools.

a very good beginner level course for those learning how to develop Data Products in R.

Great projects

Awesome Lessons!

I learned how to build shiny application and today I'm very happy!

A lot of useful parts for visualization here! plotly and shiny are super useful in a business context. swirl and leaflet a bit niche perhaps.

Demanding if you are not used to do this kind of things, but, worth It if you give yourself a time to get into it.

Great course, practical and very informative

Great course!! Was very excited with the whole process of learning to write an app and create something useful!! Thank You!

Excellent course (like the previous 8 in the specialization) and very useful for anyone working with data and involved in data storytelling. Brian (the teacher) does an awesome job explaining the concepts and how the functions and scripts in R work and interact with each other to bring about shiny apps and other visualizations. A big "Thank you!" to everyone who created this course!

I learned very useful techniques

discovery of amazing tools and possible applications of rstudio and additional packages.

good pace of the course

Very useful stuff, and nicely presented too by Brian Caffo.

The content is good and exposes to various tools and formats for building data products. Exercises for week 2 and week 3 were very simple though.

excellent course!

Awesome

Very excellent course

A lot of useful libraries and APIs explained

Very useful, very well taught. I enjoyed the project as well.

Awesome course, maybe more complex examples, but is fine as an introductory program.

nice aand easy. I do not know why you focus on creation of custom libraries withou any practical assignemens on it

Very good course for creating your own data product

Good course. I liked it.

Excellent course
