Microorganisms and hygiene habits: Is there more to be learned in Infant Education by means of worksheets?

The hygiene habits and the knowledge that a group of 69 students of Early Childhood Education (4-6 years old) have about microorganisms is presented in this work. The possible influence on them of two different didactic proposals (traditional -control group- and inquiry-based learning -experimental group-) is analysed. The information was obtained at three different moments -pre didactic intervention, post intervention and two months later-. The used tolls were children's drawings, an oral and individually applied questionnaire with closed and open questions and a questionnaire addressed to the families Indications are detected that the students recognize the microorganisms as living beings. After the intervention, no statistically significant differences were found between the experimental and control groups. Two months later an improvement was observed in the control group with respect to some hygiene habits and in the experimental group the process of investigation with petri dishes was recalled. These results open new research questions.
