學生對 密歇根大学 提供的 Introduction to Data Science in Python 的評價和反饋

I find it outrageous that in Week 4 instead of practicing python and statistics I have to spend a lot of time learning very US and sport-specific information which is absolutely useless and I am never going to need it. The same is valid I believe for the rest of the world. The coursera platform was not intended exclusively for US and Canada students? Or for people who do not have full-time jobs and a family in addition to the need to learn python?

Unfortunately, I won't complete the specialization because of this course and I will look for the content elsewhere, because of the following reasons:

1- The videos are not informative and short

2- Assignments only use like 10 to 15% only of the given info from the video

3- No slides, hints or tricks are given to help you in the assignment

4- The lecturer needs real life examples and visualization aid to support his teaching method

No or least support.

Course Quality is great but problems with grader will left you with wasting your expensive time.

Assignments are good but intend to go wayyy more beyond the scope and to learn from online materials though other sites.

Grading system is not easy. You have the right answer but you'll need to waist hours to produce specific string for your grader to be satisfied.

This i not an elegant learning process at all.

Horrible course. The instructor is reading the course from a prompter. '95% of the time, you see the instructor reading from the prompter, and two people working in the background. When they actually show the code the instructor is talking about, it goes so fast that it's impossible to read the screen. The instructor provides no motivation or background to what he says. He just rattles off the words in a uni

Instructor gives minimal examples and says "go look on stack overflow". Then he proceeds to assign problems that don't really cover what the slides, lectures, or examples were on. If I all I was trying to do was just read some docs and look on stack overflow I wouldn't need to take this course now would I?

Poorly translated and cryptic instructions for assembling furniture are better than what you get here.

The assignment is much more harder than what I learnt through these videos. I know the professor want us to learn more by searching on Google, but it really took me a lot of time to find the answer for every assignment! I attend this course only because I want to learn Python easier than self-learning, but this course make it become much harder for me and I even think of not futher my study in this area.

I am an engineer and I use matlab and stata for data analysis and currently taking Machine Learning course by Stanford which is fabulous. I did not like this course for the following reasons:

1- bad course design structure

2- so confusing and inappropriate sequence

3- super fast without providing any intuition

4- no fundamental explanation

5- course could be longer and spend enough time in each subject

Whilst the course material was great, the actual program is very poorly managed. The assignments and lecture notes are not kept up-to-date meaning you must waste hours in the forums trying to figure out why your assignments are not being graded correctly or why your code is outdated.

Not impressed, would definitely not recommend. I ended up having to just teach the material to myself

This course is no good.

Unable to run the assignments at my comfort. Half the time there is some issue in submitting the code in jupyter and with hard pressed timelines at work this does not take me anywhere. As a data scientist with little programming background, it is difficult to enable our journey with this course.

Sorry to say. This is a big disappointment for me.

This is not a course. The videos and resources provided do not provide sufficient insight to properly learning Data Science or even getting through the assignments. Content and assignments have rarely anything in common. I would have to spend more than 12 hours to solve one of the assignments. Do not recommend, you are better off leaning out of google.

The descriptions of assignments (especially 4) are not very clear. It wastes our time searching what's wrong (you can see the same question is raised up through the years in discussion forum), which always is just because the formatting issue that is not explicitly stated or different interpretations. The assignments should be extensively updated.

Not really an introduction course. The lectures are moving very fast, without really explaining the material. The assignments are much more complicated than the material learned during the lecture. Almost not related at all. I had to learn everything from google. Not for beginners!!! This course will take all your free time and will to live...

Waste of time. If you know python, you'll probably learn nothing new here. If you don't, the professor goes into WAY too high a level, and quickly, for you to actually learn anything. Moreover, he barely touches on why any of this is important, does not go over scikitlearn or numpy, both very important in data science / machine learning.

The courses/videos do not cover most of the topics which are needed for assignments. Have to Google or read lot materials in order to pass. Furthermore the videos are extremely boring as well. This course is not main for the learners who just started to learn Python, as this will demotivated the passion of a person to learn Python.

1. Very difficult to follow and I had to redo this course multiple times to understand the concepts.

2. Feels like the tutor is just reading off a screen and not explaining a topic from his standpoint.

3. The assignments and course topics are disjointed at times.

4. Examples provided are rather complex and needs to be simplified.

Un curso poco práctico, los vídeos son demasiado largos, dando vueltas sobre los mismos conceptos básicos y los ejercicios son bastante complicados en relación al temario (se espera que se busque por internet en páginas como Stack Overflow). No se trata nada de algoritmos, es casi todo limpieza de datos y cambios de formatos.

The pace is too fast! I can not keep up with the course content :(

I had studied "Python for everybody" specialization and "Python3 programming" specialization before. I thought I am now ready for this course but ....

I am going to study some introductory books or find other tutorials first and then come back to this course.

The videos are extremely short and do not feel as if they have the assignment in mind, the lectures do not teach you much compared to what you teach yourself trying to get through an assignment. The majority of time completing this course is spent reading through documentation and other external resources on your own.

A large disconnect between material and assignments. Video lectures not very good and much to short. Assignments had a lot of very annoying data cleaning etc as opposed to better understanding of data frames and pandas, while this is indubitably important in real data analysis it seemed a bit early to bring it in.

Week 4 assignment was the reason I didn't finish this course, even though I am actually a data scientist already. The task was too much focused on manual curation and googling of irrelevant information (sports teams). I'm not from the US and found this task ridiculously boring, irrelevant and frustrating.

Teaching material is poorly organized, and more of information covered in the assignment are not covered in the teaching material. It truly "self study" course. Just skip the video and dive into google. Even assignment question need lot clarification as well. Auto grading is a nightmare.

waste . your videos were useless cause you havent thought much . all the assignmnets were out of portions then what is the point of me seeing your videos if your assignments are all out of portions . worst course ever the only good thing is that the assignments were challenging

The instructor sucks. He writes codes in the video and does nor explain the logic behind it. i can find the code everywhere, what I need it to learn why we do it? Most of the time you find find yourself staring at the instructor's face, not codes and explanations

Terrible course. Assignments are extremely buggy and often touches on things not even explained in the lectures. Mentors are not active. Explanations are sketchy and not well paced. Do this course only for the examples in the Jupyter notebook.

This course was very dissapointing, the instructor only explains what is going on in the code and does not provide any explanation on how to structure lines of code. Professor Charles Severance is more engaging in teaching coding languages.
