The understanding of

algebraic language in university preacademic students.

We had asked them to translate some statements into

algebraic language. One statement was this:

(The one for Purdue's Datatron was also running in 1957; the succession of

algebraic language compilers and assemblers were designed and built for the 650 by Perlis, Joseph Smith, Harold van Zoren, and Arthur Evans.)

They could symbolize this rule both in the spreadsheet and in

algebraic language. Such movement from considering the specific to considering the general is fundamental to algebraic thinking.

A laboratory study to test the usefulness of LPFORM relative to an

algebraic language found improvements in problem correctness, time to formulate and user satisfaction.
