The problem of reliability when evaluating teaching efficiency: a methodological alternative

Isabel Pascual Gómez y José Luis Gaviria Soto.

This article deals with the following issue: When reliability indices of teaching evaluation at university level are broken down into students personal components and contextual components, reduction of reliability is expected.

Results suggest that it is necessary to consider a methodological alternative to reliability calculated with traditional methods, and to interpret cautiously results obtained from questionnaires, especially if they are going to be used for summative assesment by members of the academic authorities.


Key words: Hierarchical linear models, reliability indices, teaching effectiveness
