answer:Take a constructivist approach. Draw and build on their existing knowledge. They are coming to the class with some understanding of what they need this system to do. They have probably used other systems. Use active learning strategies. Rather than lecturing them, facilitate. So use short demonstrations but then get them trying to use the system themselves. Set problems for them to solve using this system. Get them to work together, make it as interactive as possible with you working with them rather than lecturing them. Keep in mind this is about providing them with a learning experience, keep their needs as your priority. You could put together some hand outs, and some authentic tasks they can work through as a group and individually. Provide some takeaway materials they can refer to after the class.
