Are you sure about that bolded part? The validity of these tests is absolutely at the heart of this conversation – not some other conversation – if you are going to start accusing teachers of teaching to the test in order to hide something.
Schools should be the FIRST ones we listen to regarding the usefulness of tests. My school has nearly 300 students who are required to be tested on their English language acquisition. This testing is so complicated that it takes the entire month of January to complete it – meaning the teachers who are supposed to be taking small groups of students daily to work on their English language acquisition are instead giving tests. Because these tests measure listening and speaking skills (not just reading and writing), large amounts of time needs to be scheduled for the one-on-one speaking and listening portions of the test.
Incidentally, our teachers don’t teach to the test, but they absolutely take time to teach students how to take tests – how to understand what questions are asking, how to weed out wrong answers to be left with two possible good answers to choose from, how to construct effective written responses, how to click and drag, how to highlight sections of text, etc.
Why do they do this? To raise test scores. Without taking this time, students cannot show what they actually know, because the questions are sometimes designed to assess the ability of students to figure out convoluted language, rather than the subject matter supposedly being assessed. And without taking this time, these tests would be assessing our students’ ability to use technology rather than their knowledge of math, science, literacy, etc.
And why is it important for our test scores to be as high as possible? Because our jobs are on the line based on these assessments.
So yeah, validity matters.
