Molander et al. (2001) discuss the importance of proper sign language usage in chemistry
experiments. With regards to deaf learners not being able to visualize, there could be
several reasons for this. It has been documented (McIntosh: 1995; Andrews: 2004) that
deaf learners have had insufficient opportunities of play and incidental learning, which
could result in deaf learners having limited schemata. Vacca et al. (1991: 138) state that
schemata reflect the background, knowledge, experiences, conceptual understanding,
attitudes, values, skills and procedures of an individual.
