Development and Standardization of Teacher Effectiveness Scale (TES)
Teacher effectiveness plays an important role in teaching–learning process. The present study was aimed to construct, develop and standardize Teacher Effectiveness Scale (TES). Investigators outlined the Teacher Effectiveness Scale (TES) with a thorough reading of the literature and after analysing the content framed 170 items related to the course. The prepared 170 items were revised and edited carefully and then given to the subject experts for their valuable suggestions and corrections to ensure its quality. Thus the content validity of the tool was established. Face validity of the scale was determined on the basis of opinion of the specialists. After first tryout and seeking the opinion of the experts some of the items were reframed and 31 items were deleted. The remaining 139 items were subjected to item analysis. After second tryout 65 items were deleted and 74 items were retained and those items were selected for the final study. Reliability of the questionnaire was 0.82. The predictive and concurrent validity were 0.79 and 0.77. Simple random sampling method was adopted for the selection of 200 samples. Item Analysis was done by calculating the Difficulty Index level and Discrimination Power for each of the 139 items of the pilot study. Mean values (M) were calculated of different variable for grade norms.
