I'm considering the different approaches we can use to introduce new concepts or skills to students, the part of a cycle which probably comes before students applying/practicing etc. Not neccessarily maths specific, but I've got: - Chalk and talk - the teacher describes/demonstrates it. Students probably copy notes. Students teach themselves from printed or electronic resources. Teacher probably provides some kind of structure, e.g. specific questions to answer. An investigation or problem which draws out the new information. Teacher probably clarifies the new and relevant information in a review/plenary. An electronic resource, such as a video clip or MyMaths lesson is used as an alternative to the teacher's voice. Can anyone think of any I've missed, or ideas which could be sub-divisions of those above? Also, does anyone know of any writing or research which goes in to how to introduce new maths?
