Presentation Transcript

  1. IDDEAS Introducing Desirable Difficulties for Educational Applications in Science • Broad Goals: extend laboratory research on learning and memory to classroom environment, explore interactions b/w DDs • Narrower Goal: Implement desirable learning difficulties in a web-based science module for 8th graders, with aim of improving effectiveness of such modules

  2. Web-based Inquiry Science Environment (WISE) • A system/tool for scientific instruction • Promotes knowledge integration, collaborative learning, visible thinking • Contains modules on a wide variety of topics, with options to customize and to create new modules

  3. WISE User Community 2001 Teachers and Students

  4. Interleaving Background

  5. Generation Background

  6. Life on Other Planets • Undergraduates, UCLA • 8th grade students, UC Berkeley

  7. Design Overview • 2 sets of learning stimuli • Mass of planet effects habitability (m) • Distance between planet and sun effects habitability (d) • Presentation • Blocked (mmmddd) vs. Interleaved (mddmd) • Read vs. Generate notes • Test • Immediate posttest? • 48 hour delay

  8. Some issues we’d like feedback on • Interleaved blocks vs. interleaved facts. • Formats for generation. • # Slides between stimuli and test. • Immediate posttest?

  9. Some Sample Generation Formats Text Stimuli: Weight is the pull of gravity on an object located at a certain point. … If you were farther away from the earth (like in the space shuttle) the earth’s gravity would have a weaker pull on you and you would weight much less. 1. Exact phrase: If you were farther away from the earth (like in the space shuttle) the earth’s gravity would have a weaker pull on you and you would weigh much _________. 2. Exact phrase, cued recall: If you were farther away from the earth (like in the space shuttle) the earth’s gravity would have a weaker pull on you and you would weigh much l _ _ s. 3. Rephrase: The earth’s gravity has a weaker pull on a person when they are farther from the earth’s surface. So, you would weigh _________ if you were on the space shuttle. 4. Conceptual question: A bird standing on the ground weighs a bit ________ than a bird flying high above the clouds.
