Loved this course. Great professors and I really learned a lot.

Just love it.....

IM LOVING IT!

It was nice to be exposed to new ideas. This course made me think.

A truly fascinating course. I have only a limited knowledge of science, but I have a growing fascination with astronomy and origins of the universe, life and the possibility of other life one day being discovered beyond Earth.

This course has allowed my to explore this fascination, even if it has stretched my understanding of scientific formulas and calculations. And I maybe still just as clueless about particle physics and Higgs bosom.

Thoroughly enjoyed this course. The assignment was also very appropriate, I enjoyed the challenge of complet

Everyone should do this course! The ongoing assignment is challenging but well worth the effort - it will open your eyes to connections that you may never have thought about.

Interesting course, learnt how to create little big-histories

I give my deepest thanks to all the teachers who shared their knowledge in this excellent course and especially to Professor Esther Quaedackers and her principal instructor. I found the learning acquired through all the modules of the course to be very valu

Very impressive course, let me think and learn a lots.

Very exciting course for me.

Curso Excelente que ofrece una visión general de la historia a través de un emocionante formato, muy recomendado

Enganging and empowering! The little big history assignments seemed rather intimidating at first, but it greatly helped to engage with big history more deeply. Don’t hesitate to switch sessions and take more time to think and write the assignments.

Really nice course, especially liked Module 3 about more recent history!

Great subject and team. Many thanks.

I really enjoy it! In a few weeks make me feel more smart and fulfillful.

es un curso muy bueno! Lo amé

Fantastic diversity of top teachers from so many disciplines all tied together to show the Big Picture! Thank you all!

Another very innovative presentation of the history of the universe. This course shows the interrelationship of the various disciplines of academic study. No single discipline can be used to explain all the history of the universe. The selection of various subject areas, and stated in the beginning not all inclusive, allowed me to see how multiple ideas can interact. Thank you for a very interesting course.

Dear Dr. Quaedackers,

I have just finished the Coursera course, Big History: From the Big Bang until Today, and found it a very worthwhile experience. If you can bear with me, I have a few (hopefully) helpful comments; if not please metaphorically shred this email and place in the bottom of your canary cage. The canary is optional.

The course was well organized both per presentation and per weekly topic, and the tempo of the course was appropriate. Having a transcribed text to accompany each presentation was quite helpful, although at times, due to the text being voice-prompted, the accents of the various speakers produced unique spellings, initially difficult to recognize as English. [Please note that were the arrangement reversed and, say, my American English accent were to be voice-morphed into Dutch spelling, who knows what would be produced! So, this last is not a criticism but rather an observation.] In particular, I found the combination of both a narrative approach to Big History and a conceptual one, the concepts being embedded within the overall narrative, a very effective mode of presentation, especially with the ultimate expectation of students producing a Little Big History on some personally valued topic.

With regard to the presenters themselves, all come off as experts who are genuinely motivated by the nature of their fields of study and by their responsibility to present in your course. While I did not complete a head-count of the total number of presenters, it was certainly in double digits and possibly in the twenties; what a nightmare to schedule and organize! My hat is off to you and your staff on this last point. While time per presentation is of the essence and the focus of the course was well established, it would have been interesting to have each presenter, either as a portion of their presentation or as a text addendum to the presentation, comment on the perspective that Big History gives to their specific research. Moving on…….

My formal training is in biology and at the graduate level, zoology with emphasis in ecology and evolution. This last is mentioned so you can take what follows with a grain of salt, i.e. my comments are biased by my background and are unnecessarily ladened with expectation. It would have been nice if the portion of the course dealing with the history of life spent a bit more time on mechanisms, specifically with respect to recovery from mass extinctions, and it would have been equally nice if comparisons of evolved complexity of succeeding ecologies were made between mass extinctions. Penultimately, after the Permo-Triassic extinction Lystrosaurus is the only large terrestrial vertebrate to appear in the fossil record. This poses some interesting ecological problems with respect to food source, predators, pathogens, and biomass, perhaps worth some consideration in a future version of the course. [Note here that Wignall (2015) suggests a slough of extinctions occurring over 80 million years beginning just prior to the P-T boundary and extending to the end of the Triassic and into the early Jurassic. Also note that Wignall suggests that biomass recovers quite quickly while biodiversity requires significantly more time to recover. If correct, this is an interesting phenomenon associated with recovery from collapse of complex systems in general!] Finally, convergent evolution should be considered more thoroughly both in temporal sequence, e.g. Phytosaurs to Crocodilians and with respect to the convergence of adaptive radiations themselves, e.g. Marsupials v. Placentals.

In closing, your course is excellent, and I would recommend it without qualification to anyone wishing a broader perspective of who we are, where we’ve been, and where we’re going. In conjuction with your course, I purchased Prof. Spier’s Big History and the Future of Humanity and found it a very worthwhile companion. The assigned writings were excellent and the capstone project very effective. Well done here! I do however have some concerns regarding the use of multiple choice questions, particularly when the payoff for being “correct” is so heavily skewed toward making errors; reward for learning should not be so constrained. Also, the position of Big History within formal academics, something that is currently only now being established, might be a valuable discussion topic to consider in the future. Further, asking students to submit their own unanswered Big History questions at the end of the course might be enlightening to both the student population and the presenters. Beyond these few admittedly narrow concerns and as mentioned previously, this course is excellent.

Many, many thanks for a first rate educational experience,

Tony Harper

Phenomenal.

interesting course

Awesome! I'll watch these videos over and over again!

Great course with a bunch of wonderful and exciting concepts. I totally enjoyed the course! Thanks so much.

Its a excellent course, teachers explain many interesting things about the space, the history of the universe, our planet and the future of the space explorations.
