role of experiential learning
Role of Experiential Learning
  • Knowledge taught in a single context is less likely to support flexible transfer of knowledge.
  • Laboratory modules:
    • Develop intuition and deepen understanding of concepts
    • Apply concepts learned in class to new situations
    • Experience basic phenomena
    • Develop critical, quantitative thinking
    • Develop experimental and data analysis skills
    • Learn to use scientific apparatus
    • Learn to estimate statistical errors, recognize systematic errors
    • Develop reporting skills

  • Exercise #3: Rank the top 5 most important laboratory experiences
role of technology in learning
Role of Technology in Learning
  • Bring real world problems into classrooms
  • Provide scaffolding to augment what learners can do and reason about on their path to understanding
  • Increase opportunities for learners to receive feedback; to reflect on their learning process; to receive guidance toward progressive revisions that improve learning
  • Build local, global communities of teachers and learners
  • Expand opportunities for teacher learning
