Reflection: Performance Tasks Acid Base Test Prep - Section 2: Do Now

 

A fair assessment is one that measures what was taught, and what the teacher expected students to learn. In order to know whether a unit test is fair, I have to measure it against what I asked students to do throughout the unit. I am talking not just about content, but also about the skills I asked students to practice.

In looking at my practice test, I notice that I have worked hard to write a fair assessment. Even giving students a practice test is, in my opinion, a reasonable way to help students prepare for the actual test because it gives them the chance to see the type of content and skills that I will be looking for.

In terms of how well the unit prepares students for the test, I know that as a class we spent some time on each of the topics and skills found in the practice test: acid-base theory; pH; converting between pH and concentration; writing neutralization reactions; calculating molarity and solving titration problems. All of these have corresponding lessons in this unit.

After each test, I always ask my students if the test was fair. They roll their eyes. They have come to expect that the test is fair. This does not make it easy for students—they still have to put in the work in order to do well on the test. However, I do not think it would be fair if I put something on the test that we did not cover in class.
