Student-Produced Videos Demonstrate Practical Physics Learning ! George Muncaster Scottsdale Community College Agenda Abstract Physics 101 = 1-Semester Survey Course Change Motivator: Current Environment Video Assignments Example Videos Results & Assessment Lessons Learned Future Goals/Plans Abstract Among several SCC Physics trial innovations is substitution of a student-produced video for the traditional pencil-paper LAB Final Exam. Requirement: Short video informing an experiment NOT performed in the course “Under duress”, students form teams. Each chooses an experiment topic & produces a standalone video Initial Results are Highly Encouraging: Practical Learning Positively Demonstrated Students more actively engaged than before Plans to continue & enlarge efforts Physics 101 – Intro. To Physics Introductory & TERMINAL physics course LAB is a Required, BUT “No Credit” course Lecture = 4 semester-hr; Lab = 0 semester-hr Lecture & Lab often taught by different Instructors PHY101 supports several 2-year Certificate & several 2- & 4-year-Degree programs Prerequisite: Introductory Algebra High School Algebra 1 / 2, or Remedial Intro. to Algebra(e.g., MAT090/91/92) Competencies & Outline published online: http://www.maricopa.edu/curriculum/M-Z/076phy101.html Wide diversity in student backgrounds (& impediments) “Environmental” Issues 10 – 12 Independent Labs each semester Time-limited exercises also limit understanding Most exercises require new & different equipment to be learned, calibrated, used, (and often then FORGOTTEN) IMHO: “+” & “-” Learning Issues Many Independent Lab Exercises can capability “Follow-the-Leader” (or copied) student results MAY lead to lack of integrated lecture-lab knowledge How to balance Inquiry &/vs. Directed Learning Difficult to Assess Take-away Learning in a Terminal Course Students ARE Grounded in the Information Age! Some Physics “Innovations” Lab Classes Twice vs. Once per week Greater “Less Is More” Assignments More Home (Out-of-Class) work Course Notebooks Even MORE Technology Online / Hybrid learning components “Guest” Instructors Field Trip in lieu of a standard class meeting Fewer, Longer Labs each semester Etc. (This talk is about one such Etc.) Lab Video Final Exam Assigned in one PHY101 Section during Summer 2009, Spring 2010, & Summer 2010 Students Design, Produce & Edit a Lab Experiment Video in place of Lab Final Exam Value: 25% of Lab (~7% of Course) Grade Product MUST be a full scientific Experiment NOT a: Demo, Diorama, Recipe, etc. 2-Person Team Collaborates & Shares Score Videos Screened at Last (Final Exam) Class Guidelines College equipment available for use on a non-interference basis Students submit preliminary Plan: ID Team & Experiment Equipment & tools needed Key Experiment Steps Key Formulas Storyboard (Action Sequences) Storyboard due at (End of Course - 2 weeks) Example Videos Electrical Resistance Rubens’ Tube Pascal’s Principle Baseball Energy Buoyancy Roller Coaster g-Force Atmospheric Pressure Molecular Weight of Gases on Balloons Diet Coke-Mentos Physics Bullet Velocity Thermal Expansion Young’s Experiment Heat Capacity of BBs, Chocolate, Salad Oil Buoyancy Roller Coaster g-Forces Results Only 1 Team failed to submit a Final Exam video in the 3 trial Sections (~45 students) Video Scores Mirror Paper Exam Scores BUT, NOT Correlated To the Same Students (?!?!?) Many overall EXCELLENT (A - A+ grade) Videos & Many overall POOR Videos (D grade) Poorer (lecture) students make BETTER Videos & Raise their Grades, while Better (lecture) students most often produce less effective videos. This effect raises the course average GPA! Students rate the Video Final experience as HIGHLY Positive, despite: MUCH more work MUCH more thinking / preparation required (???): MUCH more takeaway Interest in Science (???) Assessment Many Excellent Videos DO NOT USE ANY COLLEGE PHYSICS LAB EQUIPMENT !! Videos production proves the EASY Part !; Applying Proper Physics TECHNIQUE is the hard(er) part ! Minor Errors Can Easily Sabotage a Potentially Excellent Video Little Instructor Time Needed to Guide Assignment & Assess Results, ( BUT . . . In Practice, watching each video many times is not only inevitable [but (GRRRRRR !) much FUN!)]) Instructor intervention is NOT Needed to make Draft Videos Significantly BETTER Lessons Learned Loopholes: Students WILL Find Them ! Pay Attention to Student “Progress” Hands-On Skill Does NOT == Learning Rigor CAN Easily Be Edited OUT, so must insure clear and intelligible: Graphs Top-Level Introduction (What does video teach?) Explanation of In-Process “Why?s” DRAFT Video Submittal Can Convert a “C” Product into “A” Product Don’t Need Much Equipment To Conduct Many Exciting (YES! WOW!) Experiments! ?? Could Some/Much Existing Lab Equipment Now Be OBSOLETE ? Future Work Goals Revise Existing PHY101 Labs Move Some Labs Outdoors SCC to Make & Use a Rubens’ Tube Address How To Channel Demonstrated Student Interests into the LECTURE Classroom ! ? ! ? Rethink the Utility of Traditional “Modern Technology” Physics Equipment ! Develop New Labs to Leverage Modern “Information Technology” Multimedia Capabilities To Begin…
