SILVA, Antonio Denilson Leandro da; VIEIRA, Elizabeth do Rosário  y  FERREIRA, Wagner Pinheiro. The theme of food preservation in the teaching-learning content of chemical kinetics. Educ. quím [online]. 2013, vol.24, n.1, pp.44-48. ISSN 0187-893X.

This article derives from a survey of second graders from high school in a public school located in São Miguel do Guama, Pará It on the perceptions of students on the theme of food preservation in the process of teaching and learning content of chemical kinetics. It deals with the perceptions of students on the theme of food preservation in the process of teaching and learning of the content of chemical kinetics. Our aim in framing questions pertaining to this article was the fact that seek to identify the methodology used by the teacher allowed the student to have an understanding of the practical situations of everyday life that require the taking of certain decisions and if they could establish a relationship between the topic addressed with the specific content of chemistry, based on everyday observations. To this end, there was the application of 25 questionnaires for data collection. The data showed us that the majority (68%) gives students failed to articulate the theme food preservation with the chemical kinetics. This leads us to infer that the use of alternative methodologies in teaching chemistry, and the improvement of students' preconceptions are important in the process of teaching and learning of chemical content.

Palabras llave : perceptions of students; chemical content; teaching-learning chemical kinetics.
