Bridgebørn fáa betri úrslit í vanligum royndum
Dr. Christopher Shaw, ein granskari úr Carlinville, Illinois, almannakunngjørdi í 2015 eina frágreiðing, sum vísir, at børn sum spæla bridge fáa betri úrslit í vanligum royndum enn børn, sum ikki spæla bridge.
Kanningin nýtti “The Iowa Test of Basic Skill (ITBS)”, sum kannar fimm serstøk frálæruøki:
“This test structure and scoring scale allowed a comparison of the performance of five non-bridge groups of students to one test group of bridge playing students on all five subjects.
The database tracked the scores over three years to see how much gain the two groups made. The standardized testing schedule in the Carlinville schools has the kids taking the ITBS in September of 5th grade, April of 6th grade and April of 7th grade.
Thus, the entire 5th grade in 2001-02 was tested before the bridge playing group learned how to play bridge. They were all tested 20 months later as 6th graders and again 32 months later as 7th graders. The standardized testing program used the same scoring scale for all three tests.”
