The cognitive skills involve deep learning strategies like comparing, overview skills like summarising, criticising and structuring, reviewing and generalising, schematising, and transfer skills like considering potential and essential conditions of use. Meta-cognitive skills involve planning of times and planning for leaning, realistic goal setting, orientation on goals and outcomes, regular inspection and testing and finally restarting and reflection on process and outcome.There are two main types of communication which occurs within the class named one way and two way communications. Within One-way communication, Listener has little or no opportunity to respond straight away and directly. A teacher must make assumptions about the listener's skill level, prior training, and understanding of the material being communicated. Therefore, errors like the following could be made by the teacher: making the material too difficult, making the material too simple, making assumptions which are not fully shared by the audience, thus making it impossible for them to understand what is being said. Other characteristics: faster transmission less accuracy, potential lack of common vocabulary.Within Two-way communication, there is a flow of information among and between individuals. Because of the opportunity for immediate feedback, many of the assumptions that one makes under one-way communication about skill level, prior training, and understanding of the material being communicated get tested immediately. Other characteristics: slower transmission, greater accuracy, time to develop a common vocabulary.
