Good course but many quiz .May be to reduce quiz to get more star from students.

The topic was interesting , but most of the questions need to be rewritten.

Too much focusing on history of telephony and only little focus on IoT.

Too much theory and history in the course, no practical applications.

they will not teach you how to build your own iot board

Reasonable, but slow to come to the essence.

ok

Not enough conversation on IoT (Just in the last module). Way too much time spent on history that really doesn't matter and on stuff I can find on the net. One Module to run through all of these - Circuit switching and packet switching, computer telephony (SS7) and then wireless would have been enough. The remaining modules should have gone into the concepts of IoT in greater detail and some high level technical info that someone who is just hearing about it can speak intelligently on it without having to develop my own dragon board (next course)

The course provides little to no material for study. Not all quiz questions are covered in the material provided. I had to use google to search for some o the quiz. Even with the help of google, the answers submitted aren't always accepted. The course could be improved by rechecking the quiz. One has the good choice being true instead of false.

Hay mucha información que requiere una cantidad enorme de tiempo para poder responder una pregunta demasiado extendida para que la respuesta sean menos de 4 letras.

La última parte del curso fue mucho mas interesante, debido a que la historia de la telefonía o el internet es algo que ya había visto.

Excellent title. Pretty much summarizes the entire course. Through out the entire course you will definately wonder why you are here. Your answer must be for IoT every time. If that's the case, then stay tune. If you manage to reach the end, you will also know how you got here.

Mainly disappointment in the quiz. Too many not mentioned in the lecture and takes too long to find the answer and in the end not finding the research rewarding

Most of the course is about history with fair technical information. there are topics which are discussed in less than 1 min , how can i be an expert in 1 min ?

They need to improve the teaching video length and have to cover a lot for understanding

It is good but for an introduction its too long.

the exams have no relation with the course

Good content

Too short.

This course seemed under prepared. Most quiz and test content was not included in the course material. From being involved with the student forums, this was a universal problem. I have taken over one dozen Coursera software MOOCs. This one is by far the lowest quality. Courses should be based on an outline of learning objectives and the course material should be prepared to cover these key points. Quizzes and tests should reinforce the content and follow the same objectives. What benefit can there be to build testing material that does not follow the content or relevant to the subject matter.

Another problem is the video quality. it is sometimes difficult to understand. This would not normally be a problem. However, no one QA'd the text transcript. It most be from a direct audio text translation and there are whole sections that make no sense.

If you take this course, can expect to spend a lot more time searching the internet to find answers to required tests. Alas, some answers you will never find...

This course had lots of interesting facts about various organisations and their history which I liked so much, but mostly everything were non technical which is fine but testing our knowledge in those areas didn't seem like a good idea. The questions from quizzes was totally random, that is, it was not even said about in the video lectures. At-least, a study material or an information about where to study about those things would have sufficed. The fill in the blanks type questions were too random, where we were supposed to enter the exact answer (even the spaces mattered). That didn't seem like testing our knowledge. Even though we knew most of the correct answers, we weren't able to score marks because of that. Some of the multiple correct questions had answers wrong.

You should rename it to 90s style history of comunication from Bell to nowdays with useless facts about it.

I watched almost all first block but then I understood that I learnt nothing than I tried the IoT block, but it still wordy and superficial. Use more media to show your main ideas, take a class of public speaking and stop shaking a remote all the time you dont even use it.

I was incredibly excited to start this course. The outline looks amazing. For learning mediums like this, you have to start strong. Keep up the great work, you all look like you know what you're doing. You should certainly put some polish on all these videos. It's near impossible to follow along. I'd be curious in seeing the data on how many of your students finish this course.

worst course ever. All they are teaching you is history which is fine but the worst part is that there is no link between the lectures and quizzes. I have spent hours and hours to find the answers. To make it even worse is that the all questions in the quizzes are history based.

Frustrated.

This course deserves 1 star because of the quizzes that are totally irrelevant from the topic taught in the lessons. Apart from that, there is no course invigilator to help you around. Some of the links provided in the reading sections are dead Anyway, the course is full of knowledge.

Boring, most of them are history. Don't worth it ! 1 week into the course, very boring. Not technical enough. The test basically asked people to remember things that are not useful !
