An algebra class asked: What is the smallest positive integer that is divisible by each integer less than or equal to ten? Students discovered factorials and a solution. Verifying the solution produced a series of numbers. Successive differences between entries, triangular arrays, and successive quotients finally led to Pascal's triangle. (KM)

A study examined adult readers' phrasing ability to determine (1) if passage difficulty was a salient variable in readers' sensitivity to phrase boundaries in reading; (2) if phrase sensitivity was an issue of concern for young adult readers; and (3) if difficulties in phrasing were due to an overabundant or an inadequate sensitivity to phrase…

The ability to recognize, extend, and relate patterns and sequences to numeric, figural, and word representations plays a prominent role in science education. This study provided validation information for an instrument to assess childrens' ability to recognize and extend patterns and sequence in different representational forms. A 57-item…

The processing of mental structures in perception appears to be serial, in that viewers can fill in missing parts from an impoverished stimulus following a top down process. To investigate the effects of unfamiliarity, complexity, and legibility on object and layout perception of unfamiliar stimuli, ten subjects were shown one of four ribbon…
