Based on recommendations on this newsgroup, we tried the 2day free trial of www.aleks.com and decided not to bother with ALEKS. Here are the reasons:
* The assessment was frustrating for a kid who likes to work at the level where he gets 90% rightit quickly got to the point where he couldn't do the problems and stayed there.
* Once Aleks decides you know something, there is no going back, even if it has based its assessment on only one or two questions. You are only allowed to select from a handful of topics that it thinks you are ready forthere is no going ahead or dropping back to easier material.
* There is no way to tell Aleks that a problem is too hard other than by getting it wrongan unacceptable situation for a perfectionist.
* The format is incredibly boring: a problem is presented, you type the answer, and another problem is presented. The problems (in the arithmetic unit) are all just numeric calculationsno word problems, no multistep problems, no thinkingjust drill.
* There are no intermediate steps to be entered in the problemsyou do the whole thing on paper and just type in the answer. This makes it nontutorial, since it does not encourage correct algorithms, and it has no access to the intermediate work to diagnose problems.
* The "tutorial" information is poorly written and does not necessarily address the problems that a child may be facing. In short, Aleks is not a suitable substitute for a tutor and does not make good use of computeraided instruction. It may be an adequate drillmaster for a child with a high boredom threshold.
We ordered the next year's worth of Singapore math texts and will continue with them. The price is a bit cheaper than Aleks ($33 for a year's worth of text and workbook, which takes 23 months to complete, vs. $18 a month for Aleks), and the drill less tedious. It does require a parent (or tutor) to check the answers and perhaps occasionally provide advice on methods, but the material seems to be more selfteaching than Aleks.
If one is looking for computeraided math instruction, the Math Blaster games make a better use of the computer time than Aleks, though they do not get very advanced.
