2-Dimensional Motion Test
Lesson 7 of 7
Objective: Students will demonstrate an understanding of 2-dimensional motion.
Throughout this unit students have developed an understanding of projectile motion, so the goal today is to get students to showcase that knowledge. The design of my test is meant to prepare students for the AP Physics 1 exam and includes questions on vectors, horizontally launched projectiles, and projectiles launched at an angle. So after students are settled, they get right into the exam, which requires them to create responses, justify answers with computations, and qualitatively explain concepts (SP5).
As students come into the room to take their test, I direct them to look at the screen at the front of the classroom. The screen is displaying their new seats for today I've created ahead of time using a random seating chart generator. I used this generator so that I'm not biased in where students are placed and to keep students from relying on their neighbor for answers (also known as cheating).
Once students are seated in their new seats, I review my rules for tests taken in the classroom, which they were given in print at the start of the year. I emphasize that students should not use any outside resources, are only allowed the approved materials, must turn off all electronic devices, and cannot leave the room for any reason at any time. I also inform students that per our school handbook, failure to meet these requirements will result in a zero on the exam and a disciplinary referral.
Before I pass out the exam, equation sheet, and a blank piece of scratch paper, I give the students one more minute to adjust and organize themselves.
Projectile Motion Test
The classroom is absolutely silent while students take their 2-D motion test, as I really try to simulate the environment that students will experience when taking the AP Physics 1 exam. This means that students' only resource is the AP Equation Sheet and I won't answer many questions during the testing process. While students are testing, I alternate between sitting at the front of the room and walking around the room checking to ensure students aren't cheating.
When students finish their test they bring the test, the scratch paper, and the equation sheet to the front of the room. I collect everything to ensure that students haven't written down any notes to share with students in other classes. Even after they have finished, I do not allow students access to their bags, electronics, or the restroom. The point of this rigidity is to make sure that each student has a fair opportunity to test in the same, quiet conditions.
It is always my goal to grade tests and post grades within 24 hours. Because we move at such a fast pace in this AP course, I want my students to have a clear understanding of how they are doing before we move onward to a new unit.
Our science department policy is that a test cannot be returned for students to keep, so they must request a time to meet with me before or after school if they'd like to see and review their exam. This one-on-one time is a nice opportunity to discuss mistakes, trends that I noticed on their exam, and celebrate their success of finishing an AP Physics 1 exam!
Testing also creates a great opportunity for me to reach out to parents. As I'm grading the exams I put aside any exams that earned an A. I contact the guardians of these students so that they know how proud I am of their awesome efforts. I also put aside any exams that earned an F, as it's important that parents be notified of sub-par progress in the course. It takes me only a few minutes to send out an email, as I already have some parent correspondence form letters prepared for these situations. Finally, any students that did much better or much worse than their "individual normal" also gets noted. I contact these parents to either congratulate an improved effort or voice my concerns.
