1. Proficiency Based Physics Brooke Schmidt and Eric Hawker Illinois Mathematics and Science Academy

2. Goal: Transform a standard physics class into a class that is proficiency based. This is a change in assessment philosophy from… Traditional class : Grades are an average of a student’s performance on assignments at pre-determined times. to Proficiency based class: Grades are a measure of what the student understands, independent of when they understand it.

3. Why do this? Focus on learning. Meet the needs of students of many different educational backgrounds from throughout the state. Increase engagement by meeting the student at their level. Increase ownership in learning by giving choice.

4. Student Inquiries in Physics (SI Physics) – Sophomore level course (1 st year students at IMSA) – One semester Focus of study: Beginning Classical Mechanics – Newton's laws of motion – Conservation laws of momentum and energy – Generally just in one dimension of motion

5. Flexible Pacing Students may spend more time working on a concept they are having trouble with or move on when they have mastered the topic. Minimum due dates are given for each unit. Each class begins with a whole class lesson. During work time, students work on labs, problem sets, take unit assessments (tests) and retakes while the teacher provides individual and small group instruction.

6. Important Resources Moodle or some other online course management system. Quest (https://quest.cns.utexas.edu) online problem sets.https://quest.cns.utexas.edu Turnitin.com – for much easier online grading. ExamView – used to create exams from the exam question banks. Online tutorials and other resources – The Physics Classroom (http://www.physicsclassroom.com/) – And others

9. Proficiency Based Grading Specific Learning Objectives for each unit are identified and grouped into Measurement Topics Student performance is assessed at three different levels for each Measurement Topic (A, B, C…) Students may take multiple tests (max 3) to improve their level of understanding and score. Each test is unique with different questions for each objective group. There is a focus on conceptual understanding in addition to solving computational problems.

11. Learning Objectives Momentum and Impulse: 1.Understand the differences between scalar and 1-D vector (i.e. magnitude and direction) quantities. 2. Define momentum and impulse, including knowing units for each. 3. Calculate the change in a quantity (final value – initial value). 4. Be able to solve problems and explain scenarios conceptually using the impulse-momentum theorem. 5. Be able to solve problems and explain scenarios conceptually using the law of conservation of momentum. 6. Use data collection tools including motion sensors and force probes and analyze the data collected by these tools to solve for an unknown quantity.

15. MOSART Pre and Post testing show expected improvement in student understanding of physics. Ref: http://www.cfa.harvard.edu/smgphp/mosart/ Both faculty and students have made numerous comments which have guided our changes that we have made over the last three semesters. Other Data
