課程概述

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 course should be a 5 Star course. It is challenging and requires effort. The lectures are well done but not up to the level of the quizzes. The book looks like an abandoned project. The errors and missed references to tables and equations from part one of the book to the other are too many.

Having said that, I have never learned so much about a topic. I attempted the problems in the book before I took the quiz. That makes a huge difference. A week covers 2-3 chapters in the book. I started to doing the each chapter's problems before moving on in the week. This made taking the quizzes a lot easier.

Overall I am very happy for having taken this course.

I learned a lot from the course, and truly appreciate Professor Hutchinson's (and Rice's) generosity in having delivered it. I would have benefited a from more time invested in the quizzes. They were not well edited. (Similarly, the e-book could use a good edit.) This was an annoyance more than a severe detraction, however it leads into a larger issue. I believe that the motivated e-student benefits from a more involved means of analyzing content-retention / gestation than simple multiple choice questions. In fact, one might argue that the whole idea of a MOOC is the quizzes / tests of comprehension. If you wanted to learn it on your own, you could just buy a book and go to the Kahn Academy for some videos. (This gets into a larger subject that edX, coursera and the whole MOOC experiment needs to ask with earnestness -- whether the traditional class-delivery model is sufficient in an online forum. I would argue strongly that a greater investment is needed -- that Kahn Academy is a different breed. This raises an obvious financial question -- for non-tenured editors, quiz makers, etc. But asking the money question too soon is putting the cart before the horse.) Anyway, thanks for the class, and all the best.

Most excellent course. Professor Hutchinson's presentation of chemistry made the learning experience valuable and enjoyable. The course is planned well and delivered in a most professional way. It's apparent that a lot of work went into creating this course. The use of the split screen is a good technique that fully engages the learner, and following the concept development concept throughout the lectures provides a solid foundation for moving from one concept to another.

The minor negatives are the pdf file of the CDS material didn't always present correctly (especially tables, a common problem converting Word to pdf) and some of the chapter numbers didn't match ... but these are minor glitches and did not detract from the course itself.

I can't say enough good things about this course. I kept thinking how great it would be to attend Rice University and attend Professor Hutchinson's classes. It's quite evident that he loves teaching and it shows in his lectures. I look forward to any future courses offered by Professor Hutchinson and Rice University.

Lectures are great and material is comprehensive. The only problem is there is a multiplicity of errors in the questions.

This course and the accompanying textbook explain chemistry in a very simple, ground up way that I was able to easily understand.

I am enjoying the course. I appreciate the method the professor is using for the lectures. I am taking the course for the challenge of learning something new as I have not studied chemistry since my first year of college in 1958.

This is my first experience of Coursera, although a have done many other MOOCs. This is an excellent course. I studied chemistry many years ago and was looking for a course to revise some of the topics. The subject matter is at just the right level: challenging but not intimidating. The lectures are well structured and presented, and the background reading material (provided free of charge) is excellent.

A brilliant first impression, both of Coursera and the host University (Rice).

I thank the organizers for this well-structured Chemistry course. I was sometimes overwhelmed by the amount of information given but I guess this is due to the condensation process that had to be carried out in order to impart the contents in 11 weeks. Otherwise I would have appreciated to have more exercises resolved during the lessons and to get a sheet with all the formula used during the course...Thank you again.
