Development and validation of a POGIL activity to be applied in practical chemistry classes

Abstract

Practical Chemistry classes are usually taught through the traditional teaching method, however, it has been observed that this approach has become less and less effective in understanding students about the subjects covered, with the need to seek alternative methodologies. In this sense, the present work aimed to develop and validate, through the Delphi technique, a POGIL activity to be applied in practical chemistry classes as an alternative to the traditional approach. For this, a semi-structured practical script was built in POGIL format addressing the subject of Analytical Thin Layer Chromatography (ADCC). Then, the instrument was submitted to validation by the Delphi method, being evaluated by a panel of experts composed of five judges. After two rounds of evaluation, all items of the instrument were validated, presenting a Content Validity Index (CVI) of 100%. From the work, it was possible to obtain a validated instrument that can be used in practical classes that address the subject of CCDA and that also want to evaluate the effectiveness of the POGIL methodology as an alternative to the traditional approach.
