I am willing to admit I may not have communicated the point in the most succinct way, which is why I'm open to improvement. The main point is not the wikipedia page. It is that you, as an individual (e.g. parent), can buy software that implements the Direct Instruction method for teaching kids to read (the only other software that implements direct instruction methods that I know of is "enterprise software" targeting school systems and not parents). This software doesn't come up in typical google searches and it should be the 1st by far. The book I link to "Teach your kids..." is the equivalent of the software, but since the teaching technique is non-obvious, it is better to have the software do it so you spend more effort noticing how well you're kid is getting it (able to repeat the last N seconds, the last lesson, or to skip same, etc.). Because it is non-obvious and can't be explained in a few words (nor can the motivation why this is the best) I added the other links. Writing this paragraph here would have doubled the size of the submission which I thought would increase the chances a reader would get bored and skip it. Even more background is that there are also SRA product lines that implement direct instruction, and some people may have heard of SRA. There is yet even more information, about behavioral psychology, and the theory of instruction. I was trying to be concise and intriguing, yet providing links to depth for those who want it.
