# Static Visualizations

Static visualizations are those that do not change with time. Because the learner does not interact with such a visualization, these play a somewhat limited role. This is especially true if the learner enters with misconceptions of a concept. An image of a graph or a diagram or any form of static visualization will not only not be a convincing media for showing inconstantcies in a students beliefs but will also be interpreted within the context of their misconception. This does not mean, however, that static visualizations can't play a role in education. Simply that such visualizations are more suited for building relationships between concepts than inducing disequilibrium within the misconception of the student. Static Visualizations can:
• ##### Draw an anology to another domain of knowledge.
These analogies serve to demonstrate that there are multiple representations of concept. Such visualizations serve to facilitate the creation of arcs in the knowledge network of the student. Below is a visualization of a word problem. Students first learning word problems have difficulty constructing a semantic model that represents the situation in the text. Because of this they have difficulty constructing the correct number sentence to solve the problem. The visualization below draws on the students concept of sets and counting. In doing so it makes direction between the word problem and knowledge they have of the world

• ##### Serve as an intermediate representation in the case that the concept to be learned is too distant from the knowledge base of the learner.
The in the above visualization the intermediate set representation is not meant to be a lasting fixture on the path from word problem to number sentence. It serves as an intermediate representation while the direct links are being formed. By using the set representation, however, the set/counting part of the network has become more integrated into the knowledge base. This integration can again be utilized in teaching other material.

• ##### Make salient the the important relationships within a concept.
Below is a pair of visualizations for a Stirling heat cycle. The image on the left is a temperature(T) - entropy(S) diagram. The other is a pressure(P) - volume(V) diagram. Combined these diagrams show the relationships between pressure, volume, temperature and entropy as the cycle procedeeds through the four stable states of the cycle.
