Abstract:

The present study aims develop a valid and reliable scale that could be used in measurement of teachers’ perception of proficiency regarding instruction planning. To that end, the scale comprised of trial expressions constructed in 5-point Likert type was applied on 313 teachers for explanatory factor analysis; and on 300 teachers for confirmative factor analysis. Conducted factor analysis study suggested that the scale was with single factor referred as “instruction planning proficiency”. As a result of item analyses conducted based on total correlation, it was determined that all of the items included in trial application were qualified to be included in the final scale. Factor loadings of items comprising the scale were in the range of 0.69 and 0.82. Internal validity coefficients based on the total item correlations were in the 0.66 and 0.80. Concerning internal consistency of the scale, the Cronbach’s Alpha coefficient was estimated at 0.97. All these results suggested that developed “The Scale for Perception of Proficiency in Instruction Planning SPPIP ” could be used in measurement of teachers’ perception of proficiencies regarding instruction planning
