Course: Big History: Connecting Knowledge
School/platform: Macquarie University (Coursera)
Instructors: David Christian, David Baker
Quote:We currently face unprecedented challenges on a global scale. These problems do not neatly fall into disciplines. They are complicated, complex, and connected. Join us on this epic journey of 13.8 billion years starting at the Big Bang and travelling through time all the way to the future. Discover the connections in our world, the power of collective learning, how our universe and our world has evolved from incredible simplicity to ever-increasing complexity.
Thirteen billion years in six weeks. Now that’s what I call a survey course.
I suspect this course is intended for high schoolers, maybe college freshmen, since the University offers a unique scholarship opportunity for those who complete the Verified version of this MOOC. I’m not too sure of the details – if they’re talking about one course, about a specific program, or how many students they accept this way – but it’s an interesting approach.
The course is built around their “Big History” concept of using both scientific and historical research methods to create a modern cross-cultural origin story for all humans (which is a hard sell to those who are perfectly happy with their own cultural origin stories, thank you very much) via the use of nine Thresholds such as the beginning of the universe, the formation of stars, the appearance of life on earth, the evolution of humans, and the modern era. The course defines these thresholds by four criteria: increase in complexity, the “Goldilocks” conditions that were necessary for them to happen, the changes in energy flows, and the emergence of something new, be it a universe, life on earth, or the use of fossil fuels.
The first week was a detailed explanation of this process, including a little epistemology via the introduction of a four-pronged “claim tester” – intuition, evidence, logic, and authority – to evaluate how we decide what to believe. Lots of rubrics in use here, which may be why it took all of the first week to explain them all. The rest of the course proceeded chronologically. Weeks 2 and 3 were primarily science: (cosmology, evolution), the fourth and fifth week began with archaeology and turned into history, and the last week speculated about the future. The idea wasn’t to understand any of these individual topics in detail, but to look at the transitions between the thresholds and the overall path.
As a supplement to the course videos, lead professor David Baker wrote up a set of scripts for the Green brothers’ Crash Course series on Youtube; this is available to anyone. Each week also included a timeline and glossary, and in most cases, optional articles on relevant topics. A multiple-choice quiz ends every week (unlimited attempts are allowed, though only three tries can occur in any 8-hour period) and a peer-assessment essay, graded almost entirely by completion rather than content, is required at the end of the course.
I signed up for this course because one of my mooc buddies (hi, Richard) mentioned he was taking it. To be fair, he also warned me he’d dropped it once before because it contained insufficient detail, but he’s got more science knowledge than I do so I figured I’d give it a shot. I was disappointed by the absence of detail on any individual topic, and there wasn’t any real investigation of how history and science often interact, with one sometimes impeding, sometimes enhancing, the other. I did, however, very much like an article on critical thinking from Week 1, and during the cosmology section, I did some poking around to find more detailed information and discovered something called Planck’s length which I’m quite taken with. You can get something out of anything if you put some effort into it.
I think the course is probably of far more interest to someone with limited academic experience beyond high school, or perhaps someone who wants a gentle return to academics after a hiatus. The overview approach might also make a good prelude to some of the more detailed courses like Origins, Cal Tech’s Solar System Astronomy, or UVA’s The Modern World (now available in two parts), or for that matter, any of the earth science, astronomy, or history courses floating around on various mooc platforms.
