О курсе

This course will cover the topics of a full year, two semester General Chemistry course. We will use a free on-line textbook, Concept Development Studies in Chemistry, available via Rice’s Connexions project. The fundamental concepts in the course will be introduced via the Concept Development Approach developed at Rice University. In this approach, we will develop the concepts you need to know from experimental observations and scientific reasoning rather than simply telling you the concepts and then asking you to simply memorize or apply them. So why use this approach? One reason is that most of us are inductive learners, meaning that we like to make specific observations and then generalize from there. Many of the most significant concepts in Chemistry are counter-intuitive. When we see where those concepts come from, we can more readily accept them, explain them, and apply them. A second reason is that scientific reasoning in general and Chemistry reasoning in particular are inductive processes. This Concept Development approach illustrates those reasoning processes. A third reason is that this is simply more interesting! The structure and reactions of matter are fascinating puzzles to be solved by observation and reasoning. It is more fun intellectually when we can solve those puzzles together, rather than simply have the answers to the riddles revealed at the outset. Recommended Background: The class can be taken by someone with no prior experience in chemistry. However, some prior familiarity with the basics of chemistry is desirable as we will cover some elements only briefly. For example, a prior high school chemistry class would be helpful. Suggested Readings: Readings will be assigned from the on-line textbook “Concept Development Studies in Chemistry”, available via Rice’s Connexions project. In addition, we will suggest readings from any of the standard textbooks in General Chemistry. A particularly good free on-line resource is Dickerson, Gray, and Haight, "Chemical Principles, 3rd Edition". Links to these two texts will be available in the Introduction module....

If I'd had access to this material when I first failed freshman chemistry 40 years ago, I probably wouldn't have failed. Kudos to Dean Hutchinson for bringing us his innovative approach.

This is an extremely flawed course, both technically and academically. Half of the math used in the first week is incorrect (anyone using a calculator would discover this, but I also worked as an accountant for many years, as well as previously working in the financial markets as an investment analyst, so my math skills are above-average), and even when they made one correction in the video, they missed the other 20 or so. Even the textbook written by the professor has math errors in it (such as 12 X 0.99 supposedly being equal o 11.98 - not on this plant, or any other I know of, since it's actually 11.88). There are mix-ups in what shows up in what areas of the quizzes (such as Rutherford's gold foil experiment being in the first test, but the first week covers an entirely different area), and the first quiz talks about stuff that isn't discussed at all. Please explain how anyone would know grams per litre of SF6 at sea level when it isn't covered anywhere in the textbook or the lectures or the test itself. Not once did he explain the terms diatomic vs. monatomic (only the brief blip with Avogadro and how 'some molecules must be made up of two atoms then' as a conclusion, but no way to determine which ones, and not the actual meaning of the terms that ended up on a test). Nor does he talk about what (aq) is supposed to mean, where he uses it in brackets in an actual chemical formula. From my understanding of math, I'm supposed to be able to multiple aq by the rest of the formula, but since there is no element called aq, I have to guess that can't be right and it must mean aqueous solution, rather than a solid, but again that isn't even mentioned. Less than 2 seconds of time to explain, but the students are expected to search all over the internet for the answers. Um, isn't that the entire point of taking a class? So that that someone *teaches* the subject instead of students being forced to go to Wikipedia (which is generally frowned upon by academia)? Science is supposed to be accurate, and Rice is supposed to be a top university in the US. I weep for the entire country.

The course is really interesting with the concepts and application. I could able to learn many such in the basic chemistry. Since chemistry is one of the subject, which is inter related to our day to day life, the curse is very much useful.

I am really proud to be one of the learner!!! -Dr.M.Pandimadevi, Prof., Department of Biotechnology, School of Bioengineering, SRM Institute of Science and Technology, Chennai, India

I couldn't wait to take another module everytime i finished one..😍

I love to hear the detailed explanation to each topic's concept..

Thanks Prof. H..God bless you with so much strength and wisdom as you will continue to impart your knowledge to others! 🙏💓😘
