+ \begin{itemize}
+ \item
+ challenge--bot gives students courage and encourages autonomous
+ learning. The design of challenge--bot shows how to build a
+ robot from commonly available parts. Students realize that they
+ can have a completely new idea and go build it from parts on the
+ free market.
+ \item
+ Students have taken this message to heart and brought their
+ ideas into reality. Projects include building a cat feeder and
+ fish feeder. Several students combined their robots and were
+ able to perform more sophisticated tasks. Another student built
+ the same robot, but with much bigger parts, in order to make it
+ faster and last longer.
+ \item
+ Together with Learnika, Erin and I have brought challenge-bot
+ material to Gideon Hausner, a middle school in Palo Alto. In
+ addition, we have taught challenge-bot at the hackerspaces
+ Hacker Dojo and Entropi. I also teach the material at Learnika's
+ own learning center.

+ \begin{itemize}
+ \item
+ Gideon Hausner Jewish Day School hires Learnika tutors to
+ teach afterschool programs. Because of my computer skills,
+ I have taught scratch, independent, and advanced coding classes.
+ \item
+ Individual students find tutors through Learnika as well, and I
+ teach them a wide variety of subjects. For software, we cover
+ scratch, python, scheme, and Java. After taking the
+ challenge-bot course at Learnika, students continue on learning
+ robotics topics. We cover soldering, and the robotics software
+ development cycle.
