"This module has helped me think about self-directed learners and the role of differentiation in the following ways....."
The good news is that math education is by its very nature geared toward differentiation. Take for example the fundamental mathematical basis, the proof. There are a number of ways for students to arrive at the conclusion. Not every proof will feature the same theorems, definitions, or examples. Therefore, putting an emphasis on student proofs might be one way to differentiate the learning. (Of course, given the overwhelming feeling many students feel when confronted with mathematical proofs, providing an example and even a template of how to do show may be in order.)
Focusing on diversity of examples is another method I should employ. In a room with future teachers, engineers, artists, etc., it can be difficult to find common ground. However, if we are to believe the leading experts, mathematics is the universal language. It shows up in your medical reports, your bank statements, and even in your art show judges' scores. Therefore, relating these ideas and concepts to different examples across a spectrum can only illuminate.
Many students often want the path to "correctness" to be clear. And while we can and should provide some clarity, we also need to motivate these students to be self-guided or self-directed. Inquiry learning may be the ticket. Perhaps self-assessment of current progress might be in order, along with the feedback from the teacher. The important thing is that students have the resources available.
Therefore, student samples might have a rubric or template available from the start. Students can better know and better visualize just what is expected of them. Of course, the difficult part in all of this is not stifling the students' "creative juices." You could also place viewing/editing restrictions on PDF's or Word documents, along with many other methods. The ways around this difficulty for templates at the very least seem plausible.
The benefits of becoming a self-directed learner almost indisputably carry over to other areas in life for these students. Therefore, they transcend the learning objectives; transition objectives can also be addressed. So if there is one skill that may come back directly to haunt students, it is that of self-direction.
At the core of my teaching philosophy is the desire and effort on my part to see my students become successful young men and women. Therefore, it seems that an environment that fosters self-directed learning should be at the heart of my classroom.
