We take Pascal's triangle as our example and walk you through the design process to inform the audience about different choices to be considered while building for education.

1. BIG CONCEPT
How might we make reviewing high school work
easier through visualizations?
- Manu Gupta

2. Making the problem specific
How might we make reviewing binomial coefficients
easier using visualizations?

3. Defining learning objectives
⊡ Students will be able to write and find binomial coefficients
given an equation.
⊡ Students will be able to find out combinations for objects.
⊡ Students will be able to explain combinations in physical
terms.
⊡ Students will be able to draw Pascal’s triangle.

4. Defining evaluation methods
Before Designing After designing
Evaluating problem space. Observe and interviewers to
understand if they understand the
problem defined.
Give a questionnaire after they
have worked through the
visualization to measure the
effectiveness of the solution.
Evaluating data to support problem
space.
Given, the domain space, calculate
the range of values that define our
learning objectives and problem
space.
Give a wider range of values
than defined before designing to
see if the solution works for all
values outside the visualization.
Evaluating visual choices that
support the visualization.
Trying out Gestalt’s psychology,
pre attentiveness & other design
principles to suit our design.
Conduct a lab study to verify
how well design principles that we
applied worked well or not.
Evaluating algorithm written to for
the visualization.
Write the algorithm, check for
one off errors, efficiency etc.
Check in realtime how our
algorithm performs. It is important
with large datasets.

5. Define the interactions

6. Sketches -> Visualization

7. Words and pictures make
a great read.
+
Deeper understanding

8. Interactive texts allow
students to experiment
+
Experiments with different
values enhance understanding.
