The TEAL (Technology-Enabled Active Learning) approach integrates lectures, recitations, and hands-on experiments to create an engaging and collaborative learning environment. This redesign aims to address the shortcomings of traditional physics education at MIT, including passive learning and high failure rates in large freshman courses. The initiative focuses on enhancing conceptual understanding, problem-solving skills, and communication through weekly modules, interactive presentations, and online resources. By fostering peer collaboration and hands-on activities, TEAL promotes a deeper grasp of mechanics and electromagnetism concepts.

  1. Technology Enabled Active Learning (TEAL) Redesign of Mechanics and Electromagnetism at MITCourse Redesign WorkshopOctober 17, 2008 Dr. Peter DourmashkinMIT

  2. What is TEAL? A merger of lectures, recitations, and hands-on laboratory experience into a technologically and collaboratively rich environment Technology-Enabled Active Learning Collaborative learning 9 Students work together at each table in groups of 3.

  3. Why The TEAL/Studio Format? • Large freshman physics courses have inherent problems • Lecture/recitations are passive • Low attendance • High failure rate • No labs leads to lack of physical intuition • Math is abstract, hard to visualize (esp. Electricity and Magnetism)

  4. Learning Objectives of TEAL • Create an engaging and technologically enabled active learning environment • Replace passive lecture/recitation format with interactive, collaborative learning • Incorporate hands-on experiments • Enhance conceptual understanding and problem-solving ability • Develop communication skills in core sciences • Develop new teaching/learning resources

  5. TEAL Time Line Models: RPI’s Studio Physics (Jack Wilson) NCSU’s Scale-Up (Bob Beichner) Harvard Peer Instruction (Mazur) Fall 2001-2PrototypeOff-term E&M 8.02 Spring 2003-PresentScaled-up E&M 8.02 Fall 2003-4Prototype Mechanics 8.01 Fall 2005-PresentScaled-up Mechanics 8.01

  6. Components of TEAL • Meet 5 hours a week in the TEAL classroom • Weekly Integrated Modules • Interactive Presentations with Demos • ConcepTests: Mazur Peer Instruction with Clickers • On-line Visualizations • Desktop Experiments • Problem Solving Opportunities • Online Lectures and Homework (Mastering Physics)

  7. Integrated Modular Approach Sun On-Line: Students read textbook, view online lectures and answer Mastering Physics Assignment as preparation for upcoming week Mon/Tue In-Class (2 hr): Presentations, ConcepTests, Table Problems. Tues On-Line: Mastering Physics Problem Solving and Tutorials Wed/Thur In-Class (2 hr): Presentation, ConcepTests, Table Problems, and Experiments Fri In-Class (1 hr): Group Problem Solving Session Sun Physics Tutoring Center: Help Sessions Sun On-Line: Mastering Physics Problem Solving and Tutorials for previous week Thur: Hand Written Problem Set Due Fri In Class: Short Quiz

  8. Problem Solving An MIT Education is solving 10,000 Problems Expert Problem Solvers: Problem solving requires factual and procedural knowledge, knowledge of numerous models, plus skill in overall problem solving. Develop problem solving strategies and plans based on concepts and models Problems should not ‘lead students by the nose” but integrate synthetic and analytic understanding

  9. Problem Solving/Exams On-Line Mastering Physics: • Two assignments per week with hints and tutorials • Pre-Class Reading/On-Line Lecture Questions • Pre-Lab Questions • Review problems for exams In-Class Concept Questions and Table Problems In-Class Group Problems (Friday) Weekly Problem Sets 1. Multi-concept analytic problems with emphasis on strategies 2. Pre-lab questions and analyze data from experiments Six Quizzes and Two Exams and Final Exam

  10. Rethinking Teaching Roles Instructor: No longer delivers material Graduate TA: Learn to teach Undergraduate TA: Encourages student teaching Technical Instructor: No longer hidden Students: Peer Instructors

  11. Pre/Post Conceptual Test ScoresRelative Improvement Measure

  12. E&M Failure Rate/Long Term Retention Failure Rate Increases Seen Long Term

  13. Fall 2007: Mechanics Baseline Test and Student Evaluations

  14. Obstacles We Faced Student evaluations and attitudes: negative to neutral Divergent faculty opinions about lecturing Student cultural issues: contrast between traditional courses and TEAL

  15. Lessons Learned • Develop course materials that match learning objectives • Demonstrate learning gains through objective measures based on data • Support a robust teacher training program with a focus on faculty teaching for the first-time • Address faculty concerns regarding active based learning • Develop student support by communicating objectives and rationale explicitly and frequently to students • Develop and guarantee institutional continuity • Adapt teaching to local institutional / faculty / student cultures
