Is there any benefit from not sharing your intentions at the start of a lesson? How good and clear is your teaching? This is a great way of finding out.
Start the lesson without explaining the Learning Intention, it might seem a little awkward at first if that is part of your practice. Give your students a few tasks to be working on and do the introduction but stay away from mentioning any link to Intentions.
At the half point bring the class attention to the front of the room. Ask the students what they believed the intentions are. In the beginning, you maybe need to give the students a few options to choose from, but over time, if you perform this often your students, they will get better at it.
This is a great method of getting students to think about what they are learning; it helps bridge the gap between teacher and student. You could make it more complex by asking the learner how this fit into the scheme of work and the subject in general, get the students start to think about how each lesson fits into each other.
