Right now, I am in student in graduate school MAT program, so I can be come a high school physics teacher. One of the things I am really struggling with is understanding and applying informal assessments. Beyond simple student feedback, does anyone know of concrete examples of informal assessment in physics education? Is their a specific type of informal assessment you use an educator? During the informal assessment, do you use a checklist, rating scale, anedotal notes to record observations? Can you give an example or broad template of what a informal assessment checklist/rating scale/outline might look like for a science class or physics class? What are your thoughts on using informal assessments in the classroom? Do you see specific advantages or limitations? I feel like if I had an example of an informal assessment in science or an example of how a science teacher documents their informal student observations, I would not struggle with this topic as much as I have so far this semester. I am really interested in informal assessments. Eventually, I would like create an informal assessment to help grow my future students critical thinking skills. Can you guys help me better understand informal assessment in the contexts of physics education?
