I would personally recommend a more comprehensive course of economics and various aspect of it, especially if the subject is a bit hazy - as it often is for persons who haven't studied it before. The video course below gives an broad overview to the subject as a whole. It covers pretty much everything what's important in economics - not just bubbles, but everything else as well. Most importantly, it teaches people how to think like an economist. It's a very important skill, which can be applied - not only to economics - but in general. That skill gives an insight into human behaviour - why people do the things they do, what drives them, what are the incentives, what is 'rational' vs 'irrational' behaviour - and what is the definition of them (and that is something which I'm absolutely sure 99.9999% of the people don't know what is the difference between 'rational' and 'irrational' - they might think they do, but they really, really don't) etc.

It really opens your eyes. So, it's highly recommended.
