Very good information - I loved the Google Earth Labs you guys set up for us. Really useful and a fun way to connect knowledge with real life.

This is the second time that I took this course. It was more in depth in topics than the original course, and I enjoyed it. Good presentation. Thank you.

The course is very useful, the teacher explains clearly and provides a solid foundation. I am fully satisfied.

Nice entry to geology.

An incredible course with incredible teachers and full of new and complex information. It was a dream to study this subject and now I'm trained and certified. Thank you for this opportunity to share and acquire more knowledge on this subject that is increasingly important to know, after all, the world needs to be studied and known so that our decisions are rational and not harmful to the environment. Finally, I hope that someday I will be able to study at the University of Illinois.

I love this course, though I have only audited it - I am going to do the whole course when I have more time! Professor Marshak teaches with ease, engages students and makes geology a passionate subject matter. I would love to see more courses by Him covering the other chapters of his book Essentials of geology. Highly recommended for anyone who wants to understand science in action.

The team put in a lot of effort to design this course regardless of the lectures, quizzes, lab assignments, peer-review assignments etc. Personally, I had a great time doing the lab assignments as several of them requires me to use the Google Earth app to do. I recommend everyone to take this course as it uses a novel approach to teach the course content.

Material was extremely engaging and the use of Google Earth Pro was incredible! Lesson was well-designed and structured, extremely interactive and immersive. Assignments were short and sweet, allowed me to apply my learnings in a succinct manner. Highly recommend!

It was an excellent course ! Anyone from any field of study can learn a lot of things about geology and earth science. I just love the course and the the lab of the course too. Waiting for more courses like this in future.

The professors make learning fun and fruitful. This course is interesting and provides great insights into Mother Nature and why we should protect the one and only home we have.

I am very grateful to this course and also to the instructors that share their vast knowledge about geology to students of this course. Thank you

Really enjoyed the course and will be able to use many of the things I learned to refresh some of my teachings in my classroom

Excellent course! Very informative without being tedious. Clear and concise delivery and illustrations. Would recommend!

Great course, despite the glitches in the links, etc., which seemed to be outdated. i really gained little from the forum.

Th course is really great and rich and what I rally liked is the practical work on google earth.

Me dió una fundamentación en las ciencias de la tierra. Bien explicado e informativo

Interesting content, appropriate for beginners, truly an eye-opening experience.

Course was really interesting. I really enjoyed during this course.

Excellent course on geography, the nature and the world around us.

outstanding course with clear videos and interactive assignments

very interesting to me it gives very basic information.

Very interesting and interactive course.

excelente curso

Very clear and easy to understand even if you're note native english speaker.

It would have been great to get the answers to the quizzes even in the free version.

You have to purchase (50 dollars!) the entire course in order to do the quizzes and assignments....that ruined the entire course for me.
