Potty training: by Foxx & Azrin

Foxx and Azrin have written several books on toilet training, one of which is called: Toilet Training in Less Than a Day. In their book they outline 5 basic principles for toilet training:
1) Give extra drinks. This will make them urinate more frequently so they have more opportunity to practice their new skill.
2) Scheduled trips to the potty--be consistent use a timer! (data sheet comes in handy and will tell you often to schedule trips). This can be every 10, 20, 30 minutes, even hourly depending on your child. Once your child initiates trips independently and regularly the schedule can cease.
3) Dry pants checks. You should ask your child "Are your pants dry?" also at scheduled intervals, say every 20 minutes. Have them feel to see, if they are dry reward them with a small edible item (m&m, skittle, chocolate kiss, jelly bean, whatever they like). If at any time you notice your child is wet do a dry check immediately and follow #4.
4) Positive practice for accidents. This means when your child has an accident you take them from the spot they had the accident to the toilet and back five to ten times. I agree with some experts that say positive practice is a form of positive punishment. The idea here is that they pretend they are going to the bathroom (with pulling wet pants down and back up each time) to practice using the toilet. The pros to this method is that it is highly effective--children learn quickly that they do not want to do this again and stop having accidents. The cons are that the reason it works is because it's highly aversive; children hate it. It's up to you as a parent to decide what you feel comfortable with.
5) Data taking; for reasons previously explained and to measure the success of your program.
