validity and reliability of the tools of data collection

Thus, the Math and Me survey can be said to be a valid and reliable tool for use in Turkish culture. The confirmatory factor analysis results for the scale revealed perfect fit with the construct determined in the exploratory factor analysis results.

The Cronbach alpha coefficients from the scale subdimensions of Enjoyment and Self-Perception were calculated as 0.91 and 0.88. Validity and reliability are determined in qualitative research through the consistency and objective of the data outcomes, participants, types of tests, and. The Cronbach alpha coefficient was calculated as 0.93. During item analysis to determine the construct validity of the scale, an item with low item total correlation value was removed from the scale.

In line with this, 18 items from the original scale were translated to Turkish and item equivalence between the original English and Turkish translation was ensured. Within the scope of validity and reliability studies for the scale, data gathered from 1169 primary school students had item analysis, exploratory factor analysis and confirmatory factor analysis performed. The reliability and validity of a measure can only be established by observing a pattern of results. Any evidence to be considered should cover the reliability of the measure. The different types of validity include: Performance based assessments are typically viewed as providing more valid data than traditional examinations because they focus more directly on the tasks or skills of practice. Validity refers to a judgment pegged on several kinds of evidence. Validity refers to the degree to which a method assesses what it claims or intends to assess. This research aims to complete Turkish adaptation, validity and reliability studies for the Math and Me Survey developed by Adelson and McCoach for use in determining the students' attitudes towards mathematics in the transition from primary school to middle school. Reliability and validity are the two criteria used by researchers to evaluate research measures.
