Modelling in Co-Lab Co-Lab intends to offer
learners a modelling tool in which learners can construct models of the domain they investigate and integrate the modelling process in the complete cycle of gathering experimental data, data manipulation and analysis,
forming hypotheses as model fragments, integrating the model and matching models to new data. The learner will be able to act both in an inductive (reasoning for data) and deductive (reason from hypotheses) way. The
supportive measures for modelling will be brought together on a modelling whiteboard, that offers the learner a (graphical) representation language for models, visualization devices for representing both experimental
data imported form the experimentation space, and the output of models and instruments that allow learners to compare two different models, both on the level of predictions generated and internal structure. |

ModellingModelling is the
process of creating representations of the external world with the purpose of predicting the behaviour of systems. Creating models is a core activity of scientists in order to understand the world. Therefore, modelling
should also be one of the central learning activities for inquiry learning.
Modelling tools for learners have been around for a while, examples are Modellus, Stella,
PowerSim, etc. These tools vary in the representations of models used by learners and the way they can visualize the results of using the model as a simulation model. They have in common that they
are stand-alone instruments for creating models and do not integrate in the complete process of experimentation and data analysis. |
