History of Reading on Boolean Values and Predicate Procedures

Tuesday, 5 September 2006 [Samuel A. Rebelsky]

• Extracted these problems from a combined Booleans and conditionals lab. The last version of the combined lab could be found at http://www.cs.grinnell.edu/~rebelsky/Courses/CS151//2003F/Labs/conditionals.html.
• This history for that lab can be found at http://www.cs.grinnell.edu/~rebelsky/Courses/CS151//History/Labs/conditionals.html.
• Minor updates to those problems.
• Added the problem on odd numbers.
• Added the problems on safe mathematics.

• Deleted a problem that students find both confusing and obvious. (Thanks to MP, TC, and EJ for the suggestion to delete it.)

Saturday, 9 September 2006 [Samuel A. Rebelsky]

• Updated the symbol-or-list? question to the new primitive? question.

Sunday, 4 February 2007 [Samuel A. Rebelsky]

• Moved history to a separate file.
• Removed equality problems, since they served no real purpose for students at this stage in their careers.
• Added the bigger? problem, which I found in http://www.math.grin.edu/~stone/courses/scheme/spring-2000/procedure-definitions.xhtml.
• Moved the last few problems to a new extra time section.
• Other, minor, updates.
• This version available at http://www.cs.grinnell.edu/~rebelsky/Courses/CS151//2007S/Labs/boolean.html.
