Anna Liberty chose to teach middle and high school students programming using the 1970s stack-oriented concatenative language, Forth, instead of more popular options like Python or Scratch. She aimed to give students control over technology and introduce them to software creation.

Forth was chosen for its focus on fundamental concepts and avoidance of complex syntax, making it accessible to beginners. Liberty designed a 12-session curriculum focused on a tangible outcome: students creating digital art in a custom Forth environment. She utilized Nick Morgan's Easy Forth as both the curriculum and interpreter, simplifying the learning process.

A key teaching method involved visualizing the data stack using paper plates, allowing students to physically perform Forth operations. This hands-on approach helped them grasp the Last-In, First-Out principle fundamental to Forth programming before engaging with the actual interpreter. The course concluded with students creating art or modifying a game, demonstrating their acquired skills.
