RIANO, Campo Elias e PALOMINO, Martha. Design and preparation of a questionnaire according to Delphi method to select virtual laboratories (VL). sophia [online]. 2015, vol.11, n.2, pp.129-141. ISSN 1794-8932.
Selecting computer tools to virtually operate the practical component in university education is a complex decision which involves many factors. The purpose of this article is to describe the design, adaptation, and validation of a questionnaire in order to select virtual laboratories (VLs). The methodology of consulting Delphi experts was used to identify criterions which determine LVs pertinence in higher education. Two groups of cooperative work were created, and a structured questionnaire was used; criterions or variables were included or added according to opinions provided by experts during three successive rounds. Answers were statistically analyzed. A maximum correlation coefficient of r=0.93 was obtained that shows a high validity. For reliability, the method of Cronbach’s internal consistence alpha was used with a coefficient of r=0.814, and confidence level of 95% (p<0,05), while for the method of two halves, the internal consistence coefficient in Cronbach’s alpha of the first half is 0.736, and 0.718 for the second half; resulting coefficients of the two halves test show a very high reliability index. Endorsement for its administration is composed by 10 criterions. It was concluded that the questionnaire prepared and confirmed for LVs evaluation is composed by valid and reliable characteristics.
