Data Visualization Workflow

Definitions

• Factual knowledge are the basic ideas students must know to be acquainted.
  with data visualization in order to solve data visualization challenges.


• Conceptual knowledge is the understanding of interrelationships that exist between.
  the stages within the larger structure of the process that enable the stages to function together.


• Procedural knowledge is the knowledge of techniques and methods and the ability to apply.
  them in each stage of the process.


• Metacognitive knowledge is the understanding in general as well as awareness and knowledge of one’s own level of cognition of a topic.
  

Students will be able to demonstrate their factual and conceptual knowledge about the data visualization process:

The basic stages for visualizing data.
What happens in each stage of the visualization process.
What stages are likely to initiate the iterative nature of the process.
Different techniques used to better understand data.

Students will be able to demonstrate their procedural knowledge about the data visualization process:
Demonstrate actions to acquire data.
Demonstrate the ability to change raw data into a useful format for further processing.
Implement procedure(s) to extract data of interest from a larger dataset.
Choose the appropriate visualization chart for the task/data.
Implement methods and techniques to improve the visualization.
Apply best practices for data visualization.

Students will be able to demonstrate their metacognitive knowledge about the data visualization process:

Describe, in their own words, what happens in each stage of the data visualization process.
Describe, in their own words, the iterative nature of the data visualization process.

Evaluation Matrix

Review

Score	Description (Consistently does all or most of the following)
4	Clearly articulate what happens in each stage of the data visualization process. Accurate, complete interaction between each stage of the data visualization process. Demonstrate the ability to apply each stage of the data visualization process. Discuss how output from each stage impacts other stages in the data visualization process. Clearly evaluate and appraise data visualizations for impact, effectiveness, and insight. Create visualizations that clearly show significant relationships that exist within the data, articulates assumptions and presentation of all relevant assumptions and point of view. Demonstrates data visualization best practices.
3	Clearly articulates what happens in some stages of the data visualization process. Accurate, mostly complete interaction between some stages of the data visualization process. Demonstrate the ability to apply some of the stages of the visualization process. Discuss how outcome from some stages impact other stages in the data visualization process. Evaluate and appraise some data visualizations for impact, effectiveness, and insight. Create visualizations that show some relationships that exist within the data, present some relevant assumptions and point of view. Demonstrates some data visualization best practices.
2	Identifies each stage of the data visualization process. Accurate but incomplete interaction between stages of the data visualization process. Simplistic demonstration of what happens between stages that ignores the iterative, non-linear nature of the process. Discuss how output from one or two stages impact the data visualization process. Articulates insignificant or illogical implications and consequences that are not supported by evidence (data), lacking insight. Creates visualizations that are simplistic and ignores feedback and point of view. Demonstrates a few data visualization best practices.
1	Unclear articulation of stages of the process. Inaccurate, incomplete demonstration of interactions between stages of the data visualization process. Incomplete demonstration of what happens between stages that ignores the iterative, non-linear nature of the process. Fails to discuss the impact of each stage on other stages in the process. Generates invalid implications and consequences based on irrelevant evidence (data) Incomplete presentation that ignores relevant assumptions and point of view. Fails to implement data visualization best practices.
