JUNIOR, Wilmo Ernesto Francisco. A methodological proposal to the teaching of pressure and pressure difference concepts. Ens. Pesqui. Educ. Ciênc. [online]. 2007, vol.9, n.1, pp.121-135. ISSN 1983-2117.  https://doi.org/10.1590/1983-21172007090110.

The purpose of the present paper was to develop, apply and evaluating a qualitative model of teaching to the concepts of pressure and pressure difference. It was performed two experimental activities, one complementary to another, which were discussed in the classroom with emphasis on the texts written by students. This study was conducted in a public high school from Araraquara-SP. The results were obtained from observations and notes of the students about the phenomenous observed. The findings, analized by Piaget's epistemology, showed that model teaching collaborated with the pupils' interesting and to the development of pertubations which helped a conceptual evolution of the concepts. Besides, the texts written by students demonstrated a great importance to evaluating the students' understanding.
