Target.png How am I being assessed today?[edit]

I will assess you formatively today, and make a professional judgement to what extent you understand our learning material. I will use observation, your written work, answers to questions, and contribution to class discussions as data to make my decisions.

I will also ask you to complete a self-assessment which I will use to help me gauge how well you think you understand our material in class.
