Literature-based categories were then set (e.g., Meir et al ., 2005; Rundgren et al ., 2010; Kramer and Myers, 2012) and used in the analysis. The following categories of osmosis definitions emerged: 1) not mentioning the presence of the semipermeable membrane; 2) indicating that particles pass through the biological membrane; 3) limiting the osmotic process to water molecules or liquids only; 4) indicating that osmosis is a case of diffusion; and 5) indicating tonicity or solute concentration gradient as the driving force for osmosis.…”

Exigência conceptual do trabalho prático: abordagem multidisciplinar de análise do discurso pedagógico na aula de Ciências

“…Apesar de existirem vários estudos sobre as conceções dos alunos sobre osmose (e.g. ODOM; BARROW, 1995;RUNDGREN;RUNDGREN;SCHONBORN, 2010), a prática dos professores de ciências tem sido alvo de pouca investigação. Essa investigação tem estado, sobretudo, centrada na proposta de estratégias de ensino que ajudem os alunos a superar algumas das suas conceções alternativas (e.g.…”
