The teaching of the Bohr atomic model, chemiluminescence, and luminol: analysis of the textbooks of Campo Mourão, based on the curricular guidelines of chemistry's basic education of Paraná

Abstract

The article suggests the contextualization of the teaching of Bohr's postulated with everyday social life, using the concept of chemiluminescence as part of forensic chemistry, with the purpose of instigating the interest and the critical sense of the student, showing a practical application of the chemical reaction of luminol. The study was carried out by reading and analyzing three chemistry textbooks of the first year of high school used in the Municipality of Campo Mourão, comparing them with the curricular guidelines of the basic education of chemistry of the state of Paraná. The books "Química Cidadã" by Widson Santos and Gerson Mól, "Química" of Ricardo Feltre and "Química" of Martha Reis were analyzed and they presented some distinctions based on the established criteria. A practical activity was proposed for a better contextualization with the daily life of the students.At the end of the research, it was observed that the Bohr atomic model has some deficiencies in the textbooks analyzed. In addition, because it presents little contextualization, it goes against what the DCE stands for.
