The four writing examples in this chapter approach the ESA procedure from a number of different angles. In the case of the postcard the teacher may first talk to students about postcards and/or holidays in such a way as to Engage them. They then Study the postcard looking for typical 'postcard features' and finally they Activate that knowledge by writing their own version. In the 'altering dictations' activity, the students are, hopefully, Engaged by the dictation and topic of the sentence they write down. When they alter the sentence they are Activating the knowledge of English which they have. After the discussion (Activate) which this will provoke, the teacher will give feedback on the language used, making corrections where appropriate (Study). A different kind of boomerang procedure is evident in the newspaper-writing activity. Students are first Engaged with the topic of newspapers before doing the matching task (Activate). They then Study headlines before going on to a creative writing stage(Activate). In report writing, a number of stages are gone through, giving the whole sequence a patchwork feel. Students need to be Engaged with the topic, they need to Study the language which they will need, knowledge which is Activated in the collection of results before students come back to study the structure of reports in order to produce a final piece of work (Activation).
