Short-term memory plays a profound role in the learning process. It keeps new information for
some time (an hour, a day, a week) so that the information is then ready to be used, restored and
expanded before being moved into long-term memory. Thus, a lot of repetition becomes
necessary scaffolding for ADD and ADHD children (Serfontein).
Neuroscientists are still not clear about the origin of ADHD, yet study results they have obtained
hitherto shows that the ADHD children suffer from neurological differences in certain brain
areas. Their treatment very often involves psychoactive drugs ant if it is so, teachers‟ and the
doctors‟ communication and cooperation (Howard-Jones et al. 14).
For a common teacher it is rather difficult to find enough evidence for one claim or another or to
distinguish between real research, sound evidence, personal opinion or pseudoscience. For
example, Vanderwolf says there is not enough scientific evidence to claim that child-cantered,
activity-based education and whole language method strengthen children‟s literacy skills. He is
one of those, who only want to encourage teachers to be more critical towards various tendencies
in education and to ask questions as well as look for evidence before taking things for granted
(Vanderwolf; Sharp et al. 95). That is why it is necessary for a teacher to look for all kinds of
sources available in order to stay as objective as possible.
