This weekend my family went to Henry Ford Museum in Dearborn, Michigan. This is a huge building full of the history and culture of technology in America. It has tons of vehicles, planes, and trains in it along with farm equipment. The amount of history and science in that place is overwhelming.
Now I know how schools sometimes "do" fieldtrips with a scavenger hunt of items to find and write about or some other assignment. That is not how my family does museums. We came to the museum with no pre-determined agenda about what we would learn. My family explored the various parts of the museum, looked at the exhibits, and interacted when possible. Interactive items were my kids favorite parts by far, no matter how simple it was. We talked about the exhibits and asked each other questions. I never assessed my children's learning. I just let them experience it. I (lead learner) did steer them toward things I thought were interesting or important and they steered me to the things they wanted to see.

When the day was over I knew they had learned many things because we experienced them together. I felt no desire to give them an A, B+, or C-. They did not earn a 3, 4, or 5 either. The real purpose of grading of any kind is ranking students. Even sbar is ranking students against a list of norms for their age/grade level.
I feel the same way about my applied technology class. My goals for students are for them to problem-solve, think critically, and work collaboratively. These things are difficult to assess objectively. I want students to experience challenges in my classroom and feel free to attack them without worrying about failing attempts. Educators often talk about a "sandbox" space in schools where students can experiment and play. That is how I would ideally describe my classroom. Students, in my humble opinion, get enough standards in their other classes. I give them a freer environment to explore and experiment.
Again I think sbar is a good tool for core classrooms where meeting specific standards is required. But my classroom focuses on doing and experimenting and I believe a failed attempt at solving a problem can be just as important part of learning as success. Grades are not really necessary for any of us to learn.
