The first RailsBridge teaching project is a short series introducing a 4th/5th grade class to programming. We decided to use Shoes and the Ruby programming language.
To quote one Railsbrige comment Kids want to learn something that is:
Also, Ruby is a “real” programming language that real-world programmers use for practical purposes. It is effective to teach kids skills that adults use. When I did research for establishing the curriculum goals for our elementary school, I read a lot about “21st century learning skills” where kids learn to use computers and other tech as tools, in the similar manner to how adults use those tools (beyond using “educational software” for teaching specific subjects). I find from personal experience that kids are very motivated when they are learning something that could have application outside of the classroom.
