As I get better at making the tests, I am watching how students respond. This efficiency is also allowing me to delve deeper with regard to what students readily understand and what is still confusing to them. It's also giving me a glimpse of what happens when they take an online standardized test. For example, many adept math students simply type their answers in too fast and make silly mistakes related to accuracy, not skill. And so many get weighed down with the language and simply read the directions incorrectly or skip reading the directions altogether. Then, of course, there are the precision masters who are the first ones to figure out where I could have done a better job making the test--I appreciate their eye for detail.
I think the use of Google forms is helping students to become better at metacognition, thinking about their math learning and performance. As they complete answers and solve problems, they know that they'll be scored right away and that makes them want to ask clarifying questions, take their time, and answer precisely. Further practice tests similar to the final tests give them a chance to use Google form to perfect their skill with specific standards and concepts. They can take those tests over and over again.
Finally, as I've stated before, the fact that the data is poured right into a spread sheet gives me lots of analysis opportunities which, in turn, help me to use the test data more efficiently and strategically to inform instruction. Google Form assessments are a terrific way to uplift the teaching/learning program in ways that matter, and hopefully will result in better metacognition, math learning, test taking, and standardized test scores.
