CONSTRUCTION AND VALIDATION OF USAGE OF TEACHING LEARNING MATERIAL’S SCALE (UTLMs) OF B.Ed TRAINEES

Abstract

The paper describes an attempt to construct a scale to measure the Usage of Teaching Learning Materials of B.Ed trainees. Likert’s method (four points of scaling was adopted). The researcher constructs the statements, acceptance and rejection of each one would imply a different degree of favorable or unfavorable usage of TLMs of B.Ed trainees. The statement were then screened and edited in accordance with guidelines suggested by Likert’s and others. 70 statement were retained under three dimensions such as Non-Projected aids, Projected aids and Activity based aids both positive and negative statement. Eventually, pilot study was conducted on a 100 B.Ed trainees in Chennai district. After a pilot study item analysis (Cronbach’s Alpha, Item total correlation) has been done in each items, 36 statements were retained for the usage of TLMs of B.Ed trainees scale based on Cronbach’s Alpha, Item total correlation values. The statement finally covered fewer than three dimensions (Non-Projected aids, projected aids and Activity based aids) (with 14,13,9 statements respectively). The scale was tested using split-half and also Cronbach’s Alpha method and found to be a reliable tool for measuring the usage of TLMs of B.Ed trainees. The scale was also tested for content validity, face validity and item validity.
