Abstract

This study reports on the development of a cooperative learning
attitude scale for the EFL students based on expert reviews and examines its
construct validity. Three rounds of expert reviews were conducted. In each
round, five content experts reviewed the items and rated their relevance to the
content domain and their comprehensibility. The expert panel also assigned the
items to the suggested sub-scales. After item elimination and major revisions,
45 items representing five factors with perfect reviewer consensus were
retained. Although the scale was developed via expert review, the authors checked
the construct validity of the instrument through CFA by collecting data from
136 pre-service EFL teachers. The results suggested elimination of six more
items owing to their insignificant t values or low factor loadings, which were
eliminated after two reviewers recommended to. The resultant fit statistics
supported a good-fitting model with t statistics and item-total correlation
significant across all variables. The coefficient alpha confirmed internal
consistency of the scale and that of sub-scales.
