Design and validation of an instrument to evaluate the implementation of STEAM with a focus on inquiry for learning the Solar System on elementary school

Abstract

The purpose of this article is to describe the steps for the design and validation of a measurement instrument. The importance of the analysis of the conceptual literature for the measurement of the variables, the calculation of validity through the Content Validity Coefficient through Validation by Expert Judgment and the calculation of the Reliability Coefficient of the instrument, through the Cronbach's alpha. As a methodology, the process for the construction of an instrument to measure psychoeducational variables was used, specifically explaining each of its seven phases. The results obtained indicate that the instrument has an excellent level of validity and agreement; as well as a very high level of reliability. It is concluded that there is a valid and reliable measurement instrument to measure the implementation of STEAM with a focus on inquiry for learning the solar system in primary education and that its application for which it was designed is suitable.
