This research included two situations presented to six students in the Undergraduate and Teacher{\textquoteright}s Licensure Chemistry Course at the Federal University of ABC (Brazil) involving Liquid Chromatography contents. The students were divided into groups and asked to make a decision about the best experimental conditions to separate a mixture of chlorophyll, xanthophyll and -carotene in spinach extract. They possessed different stationary phases and elements. The students{\textquoteright} explanations were recorded on an audio-visual device and analysed via computer assisted qualitative data analysis software (CAQDAS) supported by the Transana software. As a result, evidence of the collective development of a scheme characterized by conceptual relations pertinent to the structural field was identified; however, such evidence was incomplete. The interference of the teacher in the students{\textquoteright} decision making was a relevant factor during the resolution of the problems. Conceptual and logical operations of thinking (operative invariants) gaps may be an opportunity for a pedagogical intervention during the resolution of problems in the classroom. }, keywords = {collective schemes, intermolecular interactions, Theory of Conceptual Fields}, issn = {1822-7864}, doi = {https://doi.org/10.33225/pec/15.68.64}, url = {http://journals.indexcopernicus.com/abstract.php?icid=1191867}, author = {Marcelo Gouveia Nascimento and Gabriel Nicolas Garcia Alves and Marco Antonio Bueno Filho} }
