PIAGETIAN TEST RESULTS
when studies have been done thruout the country they show that the majority of
students do not have the rational problem solving powers to understand the
concepts that are attempting to be taught.
This first study comes from Renner (dr. leyden's teacher in Oklahoma).
grade --- #kids --- concrete --- transition --- formal
7th--- 96--- 80--- 13--- 3
8th--- l08--- 83--- 19--- 6
9th--- 94 --- 77 --- 5 --- 9
l0th--- 94--- 68--- 16--- 10
11th--- 99--- 70--- 17 --- 12
12th--- 97--- 64 --- 15 --- 18
Notice that nine kids were "formal thinkers" in 9th grade and only l8 were
"formal" by l2th grade.
This was not a longitudinal study (following the same kids for six years), BUT it
might be assumed that the value of spending an extra three years in school is to
have another nine students (9%) move to formal operations. Yipes!
9th grade typo: 94 vs 91
