Study for the validation of an instrument for foreign language learning

The purpose of instrument validation is to guarantee precision and validity of the collected data obtained from scientific research, survey and evaluations. The purpose of the present work was the making and validation of a survey to evaluate the level of the receptive and communicative skills of the English language acquired in the pupils at the Escuela Superior de Tepeji del Rio, in the administration program to be more specific. For this purpose, qualitative methodology of the Delphi technique was used. This process is intended to obtain a consensus among a group of experts on a specific topic and to validate the internal consistency, the calculation of the Cronbach alfa coeffient was used in a sample of 61. The alpha coefficient value closer to 1 indicates a greater internal consistency among the ítems. Out of the results through the Delphi technique, feedback and consensus among the ones who checked and evaluated the components was obtained. The calculated Cronbach's alpha coefficient resulted in (0.83), which corroborates the reliability and validity of the instrument. The contribution is the instrument to be used inside the institution with the intention of determining the potential in the development of the communicative skills of the English language.
