Comentários e feedback de alunos de Introdução a Big Data da instituição Universidade da Califórnia, San Diego

It is very easy to understand

Too little technical aspects.

need to give more assignments

More hands on would be good

it's too much basic stuffs.

Add more hands on sessions

Booooooooorinnnnggggg

Its very basic course

Basic info covered.

too philosophical

Very theoretical

Quite shallow...

Lot of talking.

Not good enough

A bit outdated

Good overview

Pretty basic

nice one

Good st

I had quite some high expectations for this course however Week 1 videos were already such a turn-off. The videos were so slow-paced that it actually became just like a lecture at uni (boring). However, at first, the content was indeed interesting for Big Data introduction. The first quiz was horrible. It was so hard, half of the questions had nothing to do with the content (in my opinion). I had to research the subjects on another websites as I honestly did not see half of them on the videos. All other tests were more reliable to what was previously learned. But the part that made me more upset was having to download and install 2 applications (this was not explicit on the programme) for the final assessment understanding and answering a 2-question quiz in which one of these applications had FOUR GBs to be downloaded. Up to this point, I did download the file. Overall I do not recommend this course to anyone. Reasons are clear: the "sluggishness" of the videos and presenter and the final/ultimate 4GB gift. They should create an online environment for this task/application. I do give a star for the assessment where we had to create a presentation of how MapReduce works. I liked that interactivity.

The content of the course is ok. The main problem is that the way the information is presented. Ilkay Altintas, who is the main lecturer, is a sweet woman, but lecturing from a manuscript is not her strongest side. It is clear that she is reading from a screen while she is looking into the camera. Anyone could do that job, and they should have chosen more of an "news anchor" type of person with better pronunciation and more flow. It's simply very uninspiring and boring to listen to. Also, 59 dollars is far too expensive for such a short course.

It covers theoretical part of "What big data is" and basic info about Hadoop. Quality of presentation slides is below average. Most of them are not readable - many fonts, many colors, some with complicated pictures, some with no information at all. Part with Map reduce is just slightly touched, not explained in details, without examples. Practical tasks from hadoop are very easy and they show nothing (just how to navigate over hadoop file system.

The basic concepts were mentioned but not explained deeply enough, so I was mostly memorizing rather than understanding. The presentation was boring, and the tests did not really test anyone's understanding of the subject matter but rather if one memorized correctly the information from the videos. I would recommend finding a more engaging course.

There is a big learning gap between the first two weeks and the third one. Some key concepts are poorly or never defined throughout the course. By the end of this course, I lack the knowledge to perform a basic big data analysis. The tools we learn how to use during the course are not particularly relevant.

Decent overview of things but the presentations seemed outdated. The material is a bit too basic and could benefit from more practical aspects. It felt like not a lot of effort was put into making the course. I hope the next few courses in the specialization are better :)
