Course is overwhelming. How can you put a 30 minute video for a class? Can you divide it or make it simpler? Tutor is not explaning, he only reads; he reads sort of teleprompter and that's it. Boring. Very disappointed. And this is not my first course in Coursera. I feel I'm about to quit, and this is the second week...

The professor teaches by reading the slides and does not even bother to explain the concepts. The course contents might be interesting, but now I'm dropping this course because they are not explaining any concepts but are just giving facts to memorize.

Prof Hossam seems to be reading what he is saying, he talks in a steady tone. did not like it.

The lecturer is just reading and it's really annoying and confusing the way he reads word by word plus most of his pieces of information are not at the slides at all.

The material is OK but the grading is terrible. Most of the grades are for peer reviews which depending on other students may never be completed particularly if your first try isn't perfect and you need to resubmit. I would not pay for the course until I had passed peer review as odds are you never will.

This a good course for people who want to explore the field nanotechnology and do their work in nanosensor field.

I find it very difficult to understand what the professor is saying.

I really enjoyed the assignments! And I was impressed by the teacher's track record.

But the lectures were difficult to follow, and I still have no idea how to get started with nanotechnologies after this course. Wish there were more details on where/how to get started and practical examples to support it.

The teacher reads from a screen and not efficiently. The course has some interesting content, but it is not presented in a good or learner-friendly way. Towards the end of the course, the subtitles do not match what he is saying, which can make it very hard to follow what is being said. The quizzes feel like they are poorly worded occasionally. The assignments were interesting but poorly designed. I say this as my final assignment was plagiarized by someone else word for word, and there is no system to prevent this from happening before it is too late.

Thank you for reading my review. I am dropping this course after a short while. Despite the instructors magnificent and rare track record... I've falling asleep here with him reading off the slides in an incongruent manner (not to mention an accent for those who may be foreign to English). Some others have complained about the same. He simply reads off the slides with no explaining, no further examples, no reiteration or analogies, the slides do not always follow his messages either (which may be cool, more info the better, but some concepts are difficult that are just spoken over). It's a very interesting subject matter but even though it's quite early I'm confident that this course will NOT help me in the future and will do as much good as some lengthy Google searches. I haven't gotten that far, but many complain about the chaotic marking scheme as well [don't expect your certificate so soon]... Would Not Recommend. (MSc student opinion)

Interesting content.

Quizzes are tricky; answers, slippery.

The second peer-graded assignment is totally out of sync with a Coursera course.

I would be nice if reader would read the text before lecture...

Thank you so much, it has been a long journey especially with the essay on IoT, peer grading is very tricky issue, I submitted the same project of (IoT) over a long time but I have been getting different grades. The course is very extensive and very rich in nanotechnology field.

This is not an easy course. There are many disciplines covered specially chemistry. If your chemistry background is weak you may have to put in the extra effort. But at the same time since it covers so many areas it makes the course fun and everyone will learn something new.

This course has helped me a lot, not only provides me with the professional knowledge, also let me feel the ideological differences between people from different areas, complete thoughts and academic impact.

Nice course. Thanks to Professor Dr. Hossam Haick & his team for this valuable nanotechnology & nanosensors syllabus. everything was done perfect. syllabus, quiz and all. Thanks one and all. Great..

The course was very good and interesting and very much informative i like to have some more courses in terms of IOT devices, web based program development and industrial automations

I have earned a lot of knowledge after this course. I strongly recommend this course to Master students of the Material Science, Physics, Chemistry, and Electronics branch.

The information of this course is very good and the excellent explanation, even for people who do not speak English is understood wonderfully, Great Course.

Course was very interesting and was connected with my field of studies. I have lernet a lot of new information and I liked my own work during project.

Excellent course, I leave very motivated to redirect my career towards the area of ​​nanotechnology applied in the field of medicine

I like the information it has and I think this course is very useful for everyone who wants to introduce himself to nanotechnology

One of the best courses I did on coursera. Well structured, nicely presented and reasonably scientifically challenging!

Good course for researcher and students who are interested learning the nano technology and nano sensors.
