Any training, even if it contains the promise implied in the words “management training” can be forgettable. IT training seems particularly prone to this. So, here are a few suggestions which may assist you in ensuring that the need for refresher courses is kept to a minimum (although it should be stated that refresher courses are a perfectly sensible way of assisting the learning process.)
One important factor when teaching IT skills is the location of the training. By far the most effective place is the workplace of the individual being taught. This allows them to use what they are learning in their everyday job which helps not only show how relevant the training is, but makes it easier for someone to remember it.
Mind maps are useful. The key to using these though is to give people the time at the end of a training session to come up with their own.
If the people being trained are already familiar with the business then a very effective way to work is to divide them into groups, show them the new system and processes and invite them to play. Ask them to come up with a presentation of the new changes.
