Cognitive Load Theory
• Three sources of cognitive load1. Intrinsic cognitive load2. Extraneous cognitive load3. Germane cognitive load
• Decrease of extraneous load
• Increase of germane load

Structured Testing of Hypotheses
1. Consider a certain initial situation2. Consider a certain modification of the
initial situation3. Formulate a hypothesis about the
effects of the modification4. Carry out the modification5. Observe the consequences of the
modification6. Evaluate and – possibly – reformulate
the hypothesis

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)?

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
