ARAUJO, Nelci Reis Sales de  e  LABURU, Carlos Eduardo. AN ANALYSIS OF THE VALIDATION AND RELIABILITY OF THE OPINION SCALE FOR CHEMISTRY EXPERIMENT SELECTION (EOSEQ). Ens. Pesqui. Educ. Ciênc. [online]. 2009, vol.11, n.2, pp.177-196. ISSN 1983-2117.  https://doi.org/10.1590/1983-21172009110202.

The purpose of this investigation was to explore, interpret and describe the process of validation and the reliability of the opinion scale for select experiments which provides measures of the convictions of the teachers when they choose the experiments. The scale of type Likert was administered to 113 participants. To validate the content, we used the pretests and pilot test techniques until the final version that from our consensus with experts in the area, we obtained good results. The parallel form and Spearman techniques verified stability in time, indicating reliable positive results. The Cronbach alpha item totaled 0.80, 0.85 and 0.7 for general, the teachers and undergraduate teachers, respectively, considering comprehension and variability of the pertinent items to be interpreted.
