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.

I enjoyed Planet Earth... and You! very much. The content of all five modules flowed naturally with the next, and it was thus easy to understand and take in all the material. The use of Google Earth Pro for the Lab assignments was also very interesting - in no other course can you travel around the world from the comfort of your home to identify the various features learnt in the lectures.

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'm astounded at how in depth the course's resources is, the weekly quizzes, assignments and lab sessions really opened my eyes to the geology of our planet earth. I now see the connection between mankind's action and the earth's impact, as well as understood the role I play in taking better care of our planet. Special thanks for Dr Marshak and Dr Herrstrom, I'm humbled to have been their student for these past 5 weeks!

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 Course itself brought me plenty of knowledges on Planet Earth by knowing the 5 different topics that have been taught. In this course i do not only just learn online lectures and quizzes but also given the opportunity to use Google Earth Pro and understanding the different features on Earth. This is a course that gives you plenty of knowledge on Planet Earth.

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!

I enjoyed the course! While it was somewhat challenging as it was unrelated to my major, the content remained largely interesting! I found the assignments quite interesting (I took it fairly seriously) as I researched and read up on.

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 instructors are very clear in their teaching and this course gave me a greater insight into Planet Earth and the phenomena that come along with it. The labs are very interesting and fun to do as well.

Excellent course. The content was well delivered. If you are not a geology student and don't intend to be one but wish to find out more about the planet you lived on, this is the course for you.

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.

Good diversity in topics covered and unique use of Google Earth for lab work that gives the illusion of visiting various landmarks all over the world.

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

very insightful with enthusiastic lecturers! Easy to follow even for people with very basic geographic knowledge such as myself.

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.

Nice to know more about the earth, etc. More information than secondary school geography.

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