Psychometric Evaluation of a Perception Scale Measuring 21st-Century Skills in Pupil Teachers

Abstract

This paper is constructed to determine the psychometric properties of perception scale on 21st Century Skills for pupil teachers. In this paper an attempt was made to assess the validity and reliability as well as to provide the appropriate standards for interpretating the results of perception scale on 21st Century Skills. The scale includes 41 items to measure twelve types of skills on a large sample of 328 pupil-teachers of different teacher training colleges. Content validity was determined by various experts of reputed universities and construct validity was calculated using Pearson inter-items correlation between items was calculated. Furthermore, Pearson coefficient of correlation between dimensions and total value was calculated. The reliability of the test was tested by calculating Alpha Cronbach. Quartile Deviation was calculated in order to ascertain the levels of perception on 21st Century Skills. Overall, it is concluded that the perception scale has good construct and discrimination validity. Moreover, all the values of reliability coefficient for each dimension are highly significant.
