Standardization of Measurement Instrument on the Base of PIAJET.S Operatory Psychology, From Childhood to Adolesc

The aim of this research is to standardize the measurement instrument on the base of PIAJETʹs operatory psychology related to concret operations Identificational level from childhood to adolescence. For this purpose, the girls and boys students of primary and guidance schools from 6 to 13 years old in the public and nonprofit schools of Tehran city were determinded as the community of study. The volume of sample was determinded on the base of formula for determination of volume of sample for 500 persons by using the classic sampling procedure. Three important tools were used to investigate the questions of research including conservation (quantity of matter) test: conservation test of (weight). And conservation test of (volume) by the clinical Interview procedure on the base of PIAGETIAN system in order to determine the procedure for the mental abilities of students. The deseriptional statistics and deductional statistics and reliability test were used to analysis the results by the retest procedure and Alpha keranbach procedure and test correction through narrative content, narrative criterion, and narrative structure synchronism for analysis of data by the computer. The results of research showed that: 1- the conservation test (amount of material, weight and volume) has the necessary reliability (end) and is acceptable and very satisfactory. 2- the conservation test (matter, weight and volume) has the necessary truth (narrative) and is acceptable and very satisfactory. 3-The procedures of operational changes were classified from the lowest level (eg: conservation of matter) to the highest level (eg; Conversation of volume)for the 6 to 16yearsold students; this finding is consistent with the view in which this investigation has formation of concepts (matter; weight) is nearly as the other counties ofworls, but the concept of volume would be considerably explained and in relay. 4- In the areas of conceps (matter, weight and volume) and increment of ages, we observed the gradual changes of achievement for conservation: the conservation of matter would be located in the 8 years old and the conservation of weight would be located in 9-10 years old. But the conservation of volume would be located in a considerable delay. 5-the effect of gender variable was not physically observed in the conversation.
