I'm confused...

What can a teacher actually do for her pre reading activity? The answer is still vague for me. For this semester, we have been assigned to do micro teaching for three subjects and each of lecturers has different definition and expectation for the pre reading activity. Some say it must be done without introducing the text and some say it must be held with the text in the students’ hands. So, which is the actual way of conducting pre reading? I have chosen some extracts from the play “The Ring” and asked the students to match it with correct explanation. The extracts and explanations were related to the character traits of the main character, Raj. I thought that would be an introduction for the students to actually know about the character Raj in the play. I was still dealing with the text but I did not use the whole text as reference. For a change, I have chosen 8 small pieces of extracts from the play. After that presentation, the tutor commented me that what I did was not pre reading but actually while reading. He suggested that I should give the play and ask them find the characters in the play. Can’t we do any other activities for pre reading activities other than circling and highlighting the characters? Wouldn’t that be so easy for the students as they do not actually need to go through the play? They can just find the characters by looking at the side of the paper. The conclusion is I’m still blur of pre reading activity until now...
