Where’s the play in programming?

Aaron VonderHaarBarCampSD4

Why program?

What makes programming fun?

• The joy of figuring things out

• Exercising creativity

• Collaborating with others

• Each skill gives you new things to play with

Barriers to enjoying programming

• “too technical”

• hard to get the tools

• don’t know where to start

• many prerequisite skills

• no stable feedback loop

How to make programming fun

• break up new knowledge into small chunks

• each new skill should give results

• reduce the prerequisite knowledge

• make it easy to get and use the tools

• smile

Teaching Java programming

• Grades 4-12

• “Programming should be fun!”

Usability of programming tools is

a barrier

How much of a barrier?

• Setting up a programming project

• Number of steps is a crude metric

• Pre-condition:at Google search results page

• Post-condition:typing code
