2. Overview • Potentials, requirements and problems of learning with multiple and interactive representations • Facilitating learning • by reducing extraneous and encouraging germane cognitive load • with multiple representations • with dynamic and interactive representations • An experimental study

3. Learning with Multiple and Interactive Representations • Potentials • Requirements • Problems

4. Overview • Potentials, requirements and problems of learning with multiple and interactive representations • Facilitating learning • by reducing extraneous and encouraging germane cognitive load • with multiple representations • with dynamic and interactive representations • An experimental study

5. Cognitive Load Theory • Three sources of cognitive load • Intrinsic cognitive load • Extraneous cognitive load • Germane cognitive load • Decrease of extraneous load • Increase of germane load

9. Structured Testing of Hypotheses • Consider a certain initial situation • Consider a certain modification of theinitial situation • Formulate a hypothesis about theeffects of the modification • Carry out the modification • Observe the consequences of themodification • Evaluate and – possibly – reformulatethe hypothesis

11. Research Questions • Can learning with multiple representations be improved when • learners actively relate different representations to each other (increase of germane load) and • produce step by step an integration of these representations (decrease of extraneous load)? • Can learning with interactive representations be improved when • learners test hypotheses in a structured and reflective way (increase of germane load) and • are provided with informative examples of data and their attention is guided to specific aspects of the representations (decrease of extraneous load)?

13. Procedure • Reactivation of pre-knowledge • Pre-test • Introduction to the visualizations • Relating different representations • Interacting with the visualizations • Post-test

14. Results (all questions)

15. Discussion • Mental coordination and integration of multiple and interactive representations has to be facilitated • Comprehension can be improved • by reducing extraneous cognitive load and by increasing germane cognitive load • by encouraging learners to integrate different representations interactively • by encouraging learners to test hypotheses in a structured, and reflective way • Difficulty of support measures: additional extraneous load
