My students understand that they need to take the rubric, compare it to their solution, and score their work appropriately. Then, he explains that since force equals mass times acceleration, the mass and change in velocity are what will determine the force required to stop each car.

Finally, students work through three more sample problems in the same manner as described above. These notes help me to stay focused and ensure I mention the highlights as we progress through each slide.

Once everyone is situated and quiet, I give each student a copy of an AP practice problem that applies the W-KE theorem.

It also shows students what AP Physics 1 readers are looking for in a strong answer and gets students thinking about how they might score on the AP exam at the end of the year. Students turn in their scored problems at the start of the next class period and I record their grade.

The students ask questions, participate in problem-solving, and connect to real-world examples to stay engaged the entire time.

After he completes his explanation and shows a few of his calculations to support the numbers written on his paper, I end the introductory activity by asking if anyone requires further clarification.

While I describe this section as "direct instruction," I usually have a lot of interaction with my students throughout the presentation and am constantly moving throughout the room to change my proximity.

I purposely choose this AP problem so students can apply their newly-learned knowledge. Then, students are asked to apply the kinetic energy in a sample problem and share their answers with the rest of the class.

After giving students about two minutes to work on the example, I share the solution before moving on to discuss how work and kinetic energy are related. Not only is self assessment a powerful learning opportunity for the students, but it also takes some of the burden off of the teacher.

This expectation of how to take notes has been outlined and ingrained in their learning since freshman year. He starts by highlighting the fact that each boxcar must stop in the same distance, so work becomes proportional to only force. At the end of the hour, when the bell rings, students come forward and show me their work.

For each of the example problems that are included in the presentation key is viewable when the file is downloadedstudents are encouraged to collaborate with those students seated around them.

My students are operating under the expectation that they must write down key points from the presentation. Using mathematics and computational thinking Context In the previous lessonstudents were introduced to the concept of work. Work-Energy Notes Closure with an AP Practice Problem 15 minutes Student Sample Reflection Because students are already familiar with my suggestions for solving AP Physics 1 free response questions, I simply tell students to put everything away except for their calculators and equation sheets.

I choose this task because it asks students to apply their knowledge of work, specifically how work is proportional to force times distance, which is something we covered in our last class hour.

Homework problems and the unit test will contain similar problems, so at this point in the course students usually embrace the ability to have guided practice time. Providing students with the rubric as they leave the room allows them an opportunity for immediate feedback.

My changes in location help students stay quiet and focused. Once the students are settled, I read the instructions from the top of the activity. I then ask if anyone got all of the answers in the correct order.

I emphasize to students that they should work individually and take about 5 minutes to rank the graphs, explain their reasoning, and then assess their level of confidence.

During these 5 minutes of work time, I walk around the room and informally assess how students are doing with simple glances at their work. My reading of the instructions is to ensure students understand that class has started. The task should be a slight challenge, but this introduction is meant to get students thinking about work.Because students are already familiar with my suggestions for solving AP Physics 1 free response questions, I simply tell students to put everything away except for their calculators and equ.
