Students struggle with the concepts of concentration gradient, the terms hypotonic and hypertonic and the movement of water in osmosis.
Kaitlyn had scored a 3 on the summative assessment and score 23 out of 27 points to earn the 3. She felt that didn't reflect on what learning had occurred.
She sat down during our FLEX period, which is a guided study hall at the end of the day. I asked what she found interesting and confusing about the business of biological membrane transport. Kaitlyn then proceeded to rattle off ideas and concepts about ion channels and protein pumps and how they changed shape due to ATP being used.
Here was a clear example of what the assessment had not shown. This student had a clear and genuine mastery of the concepts. It was a cool conversation for me and I think she felt proud of what had been learned and demonstrated.
The fist bump between us was a celebration of moving her grade to 4.
(Some of the students get the reference when discussing the movement of "free water" in cells and the "free ice water" you get at Wall Drug, South Dakota)....some of the students, but it makes me laugh.
I had the opportunity to sub in your classroom last week. Along with reading this blog I can see how most of the students worked independently and cooperatively on their learning. The activities and assessments were used a learning tools and the teacher observed and guided. A lot of effort on your part to increase student learning.
