Validity and reliability of an online test on the phenomena of reflection and refraction of sound
Journal Title: Apertura - Year 2019, Vol 11, Issue 2
Abstract
This work presents the results of a validation and reliability process of a conceptual test on reflection and refraction phenomena of sound waves, a process that was carried out online using Knowledge Applied Technologies (TAC). The development of this process was done by using the Classical Test Theory as a theoretical framework and the use of a website for remote implementation. The use of TAC allowed the validation process to be more agile and extended to a larger sample, allowing application in several universities in Mexico, Colombia, Ecuador, and Chile. The obtaining and analysis of data to achieve the validation and reliability of the instrument was given by means of a system designed specifically for this work, which allowed the realization of the necessary statistics to obtain indicators such as difficulty, discrimination and reliability. Obtaining a test that can be applied and resolve online is a novelty in grounds of the Educational Physics.
