Alice is an interactive 3D animation software designed to teach fundamental programming concepts in an engaging way. It uses drag-and-drop programming to prevent syntax errors and appeals to a wide audience through storytelling and game development. Key features include representing objects visually and including a Java syntax mode to ease future transitions to other languages. Alice is being used in introductory computer science courses at both the high school and university levels to attract and retain more students in the field.

Software + a Book

6. The Alice Software
• A 3D interactive animation environment
• A tool for teaching fundamental
programming concepts
– object oriented
• System developed at Carnegie Mellon

7. A Demo of Alice…

8. The Alice Approach
• Uses 3D graphics to engage students
• Has a “smart” drag-and-drop editor that prevents
syntax errors
• Appeals to wide audience
– Storytelling
• (young women, minority students)
– Interactive computer games
• (young men)
– Not threatening; Alice builds students’ confidence

9. Key Alice Features
• Makes objects something students
can see and relate to
• Has a java syntax mode to ease the
transition to C++/Java/VB.net

10. How Alice is being used
• In pre-CS1
– course for majors and students considering a CS
major
• As conceptual introduction in CS1, followed
by a transition to Java/C++/VB
• Introduction to programming course
– non-majors (in business schools, for example)
– attract students to become CS majors
• Computer literacy
– problem-solving component
• Pre-AP in high schools

11. Commonly Asked Questions
• How much does the Alice software cost?
– It is free! (and open source)
• Does Alice run on the Macintosh?
– Yes! Download Mac version from www.alice.org
• Where can I go for instructor support materials?
– www.aliceprogramming.net
• Is Alice hard to install?
– Just copy files to the hard drive; no “install”

12. Commonly Asked Questions, Cont.
• Isn’t Alice just a toy? (it looks so “Fisher-Price”!)
– No -- Alice contains all the features of “real” languages
– Students can write 3,000 line programs in Alice
• How do students go from Alice to Java?
– They have learned the concepts in Alice, then learn syntax in Java
– They have built confidence and are more persistent
• Is there any “hard evidence” that Alice works?
– Yes! An NSF study on “at risk” CS1 students who used Alice…
• Increased grades from C to B
• Retention (into CS2) went from 47% to 88%
