Design And Validation Of An Instrument To Assess A Didactic Sequence Directed To Promote The Development Of Critical Thinking

Abstract

The text responds to the validation of an instrument that has been designed to evaluate the quality of an intervention proposal aimed at promoting the development of critical thinking in students of the competence assessment diploma of the degree programs of the Caribbean University Corporation CECAR. The design was subjected to a process that began with the validation of the judges, obtaining data that were subjected to the protocol of Lawshe (1975) modified by Tristán (2008), which allowed calculating the content validity index of the instrument 0.829 or 82 , 9%, which confirms the seven proposed dimensions. Also, some recommendations from the judges regarding the writing of some items were accepted. The instrument was then subjected to the process of statistical validity by doing a pilot test with 20 products, initially calculating Cronbach's alpha of 0.912, which shows a high consistency of the construct items. Subsequently, the Guttman and Spearman-Brown reliability coefficients were determined, obtaining values ​​of the coefficient of the two halves of the construct of 0.998 that show high reliability. And at the end, the goodness of fit test of the model was carried out, estimating the variance error, common variance and true variance, estimated common inter-element correlation, estimated reliability and estimation of unbiased reliability, obtaining values ​​that demonstrate high reliability and internal consistency.
