It was definitely much easier to teach in the ‘olden days’. Everyone read the same text, researched the same topic, wrote the same text type, answered the same question. The students worked hard, studied and took and passed ( apparently everyone did if you listen to the nostalgic educators and parents of times gone by) the same test.
Then along came this pesky new age world of personalising and differentiating teaching and learning with its notion of student choice and planning for a wide range of student interests and abilities. Along with it came a whole lot of challenges for teachers as they passed topic selection into the hands of the children.
No longer does the teacher have access to all knowledge being learned during the unit of work. No longer does the teacher have complete mastery over the content of the class novel. In a single Inquiry Unit, there may be 15 different topics being explored by your class. If your class runs Literature Circles or Book Clubs, there may be 5 or more novels being read concurrently. In these instances, how much is expected of the class teacher to be on top of all the content involved in the individual student’s choice?
