Kursteilnehmer-Bewertung und -Feedback für Getting and Cleaning Data von Johns Hopkins University

Its extremely difficult to install the packages. Most of the time the instructions are not clear on what packages to intall in the videos. There should be a pre-read with links and instructions on which packages are needed to be able to work on this course. Extremely frustrating, considering a majority of the time is wasted just trying to figure out how to install packages. If you are serious about success of course takers, you have to make it easier to understand and instructions have to be clear.

For such a terrible course to then change payment terms without my authorisation. Take $64 from my account without telling me clearly amongst all the other junk mail. Coursera have a lot to answer for, and this specialisation is not even worth wasting your time if it was free.

Taught without purpose; meaningless instructions given to copy without regard of the bigger picture.

First quiz states 10 minutes for a 5 question quiz. I am taking way longer due to errors in loading packages and Java. One of the question is out of date and has not been updated in a year. Quality of this course is lacking when changes are constant. The mentors say it's realistic. I'd considering dropping this course and search for a better updated one.

Packages and code shown is outdated, different file formats are shown very briefly, without any attempt to communicate understanding. If I have to reproduce code that does not work and then spend hours googling solutions to problems I would not have if this course was done properly, I prefer not doing the course at all. Waste of time.

This was a mix of everything course, nothing was completely explained. It would have been a better idea to just pick a limited options and cover them well. The description of the final project was a puzzle and the objective behind it was completely vague. I wanted to quit in the middle, but I put time and that is why I finished it!!!

Lectures and other material just don't cover the information needed in the course project. Majority of the learning has to be done outside of this course, in order to pass the course project.

I cannot recommend this course anyone who is not deeply familiar with the topic already. The course project is truly frustrating!

It was difficult to understand and no enough exercises, in addition, the questions are very hard to answer and need a lot of digging to find the correct way to answer, personally, I am not happy with this course and not intend to continue the DS program because materials are old and not reflect the exam questions.

Expected more explanation with the teaching part, detailed lecture depicting live examples is needed to explain each and every module of the course. similar examples like Assignments can be taught by hard-coding them with RStudio

hoping that these things can change with the next courses which I'm enrolling

MUito rápido o conteúdo e o fato do suporte ser somente o fórum deixa o curso vago, achei muito fraco os slides e o método de ensino.

Poderiam focar mais em exercícios e nos comandos mais difíceis, pois quando chega nos assignments fiquei perdido por não ter conseguido realizar da forma esperada.

Basically impossible to complete quizzes and course project using the provided course material. Poor correlation between instruction and testing. Makes one wonder: If I need to solicit others' guidance to complete your tests, why am I paying for your guidance in the first place?

Why are people writing extensive blog posts contemplating the vague wording of the final assignment when you could just *fix the assignment*? Also, one of the worst explanations of regular expressions I've ever heard.

There are quite a few issues with the final assignment of the Getting and Cleaning Data course. I feel this assignments lacks quality in contents, suffers from a flawed process and lack of attention by the moderator.

The instructor did not devote his time to teaching. Slides were poorly prepared. Links are not working. Although many students have raised the issues, nothing has been done for years.

Doesn't worth the effort. You learn the most by searching online tools each time you encounter a problem while solving a quiz problem or following the steps the instructor did.

almost all the videos from week 1 are outdated making it impossible to follow the course,i will propably drop it,this is something that should be addressed by coursera.

The course material was not of much help. Felt lost while doing the assignments. The instructor keeps forgetting that this is a beginners level course

I may not able to submit the peer graded assignment. please help me to solve this. My progress is pending because of this assignment

all the practical things had to be learned by self learning instead of in the course. Peer graded assignment took for ever to pass

The worst! I don't recommend you to take any course from this institute. It is just wasting time and money.

Description of assignment questions is not clear. The expected answer from the questions are confusing.

The peer grading looks weird. I got a comment on my original work "seemed to be not written by me".

final project is terribly defined. Lecturers, Coursera, and Johns Hopkins should all be ashamed.

Very scattered and unfocused course. Sad to say that I learned very little from this one.

This is just because of the unclarity of the final assignment.

Terrible! Go to Data Camp and save a bunch of money!!!!
