Predictors of Literacy
Outcomes in Teaching and Waiting Groups – A ‘Dyslexia Factor'
We found that poor verbal short-term
memory, in relation to other abilities, predicted smaller gains from
tuition. We suggest that those with specific weaknesses in verbal
short-term memory are more likely to be ‘dyslexic’ which is to say
that they have specific cognitive weaknesses that make learning more
difficult. It has been argued by some that there are no
differences between ‘dyslexic’ and ‘generally poor’ readers and
that there is no real value in distinguishing these groups on the basis
of variables other than reading. Our results provide evidence
against this view but evidence in support of a ‘syndrome’ of
dyslexia. The sample as a whole displayed weaknesses in short-term
memory, speeded information processing and phonological awareness,
typical signs of dyslexia. The outcome of the teaching
intervention is that those who ‘look more dyslexic’, in that they
show specific verbal memory weaknesses, make less progress. We
accept that this is a new, and perhaps controversial finding, and that
further work is needed in order to understand how short-term memory,
phonological awareness and naming speed are linked with reading and
spelling development. We think it an interesting possibility that
that the ability to store and process spoken words, when tested over the
short term is indicative of a more general capacity to learn the
associations between spoken words and their written forms.
Testing of progress approximately 6
months after the programmes had ended indicates that the gains made were
sustained. In general pupils were progressing at around the rate
that might be expected, but they were not ‘catching up’ as was
happening during teaching.
In the waiting group reading outcome
was linked much more strongly to initial reading levels. However,
rather unexpectedly, we found that lower Nonverbal IQ, relative to
other abilities, was associated with greater gains in reading. We
offer a number of suggestions for this result including the possibility
that some of the more nonverbally able children found ways of occupying
themselves at school in ‘other ways’ and steered away from reading
and spelling activities. In the jargon, they might not have been
engaging fully with the literacy aspects of curriculum.
Differential Response to the Teaching and HSP programmes.
We found that those pupils with more
severe reading difficulties and more severe phonological difficulities
responded particularly well to the teaching programme. Children
with these characteristics did poorly in the HSP and Waiting groups.
The difference in reading outcome between Teaching and Waiting groups
was almost 10 standard score points. On the other hand, the
pupils with relatively good reading and phonological skills did not
respond particularly well to the teaching programme – they did no
better than those in the waiting group. Children with these
characteristics who had the HSP responded much better. This is a
very important finding. It is not the case that one programme is always
best; one programme is better for pupils with one set of characteristics
and another programme is better for children with a different set of
characteristics.
The children with weakest reading
and weakest phonological skills were receiving most support in school,
indicating that schools were generally identifying and supporting
those with the severest difficulties. However, those in the
teaching group were receiving no more support in school than those
in the waiting group. This shows that the positive benefit of
teaching was additional to any benefit of school support. An implication
of these results is that the kind of support provided in school was not,
on its own, effective for children with this pattern of most
severe difficulties.
It was perhaps unsurprising that the
children with relatively better reading and relatively better
phonological skills responded best to Home Support Programme.
However, it was surprising that children with these characteristics who
had the HSP did better than similar children who had received
2 hours per week teaching. Both groups made more progress than
children with similar characteristics in the Waiting group who were
receiving support in school. This is a surprising finding since it
is these children – those with the milder difficulties – who we
might have expected to respond best to school-based support.
Qualitative Analysis
Interview and questionnaire data
indicated that two main aspects of the teaching programme
delivery characterised the improved or less improved children. Those
children who made good literacy gains had relatively good attention and
learning habits, and were committed to their lessons, whilst those who
did not do as well had more difficulties settling to their work.
This appeared to be due to the attitude and motivation of the children,
as the parents in the main were very supportive of the programme.
Some of the parents of the less improved children, however, seemed to
find it hard to either help their child with their homework, or to
encourage the child to complete the homework. There was therefore
not such a firm link between home and the teaching lessons as with some
of the children who did make good progress.
Analysis of responses of those who
had the HSP also identified two aspects of programme delivery that
characterised the improved or less improved children. Those children who
made good literacy gains had followed steady routines, whilst those who
did not do as well had worked less consistently. This was often
due to the interest and motivation of the children rather than the
commitment of the parents. Furthermore, amongst the children who
improved most, more appeared to have followed a streamlined
programme where the various element of the teaching were integrated.
The success of the programme was thus, to some extent, dependent on the
parents ability to adapt and extend the work.
Emotional and Behavioural Factors
Behaviour ratings by parents and
teachers revealed a high incidence of behavioural difficulties amongst
the sample. A very high proporition of the pupils were
rated as having Hyperactivity problems by both parents (50%) and
teachers (40%). About a third of the children were rated by their
parents as having peer problems, emotional problems and conduct
problems; teachers ratings were lower with 15 to 20% seen as having
problems of these kinds. A good baseline for comparison comes from a
study by Adams et al (1999) which found hyperactivity problems to be
present, on teacher ratings, in 12% of the primary population and
conduct problems in 8%. Thus the incidence of behaviour
difficulties was substantially raised in this sample of children who
were initially chosen as having literacy difficulties.
Qualitative and quantitative analyses revealed problems with attention
and hyperactivity to be a significant additional barrier to successful
learning, although some very good results were achieved by some of these
more challenging pupils through one-to-one teaching.
Changes in Self Esteem
Results of the Harter Self esteem
questionnaire showed that there was a significant overall improvement in
self esteem over the course of the intervention. However,
when the groups were looked at separately, only the home support
children’s self-esteem results improved significantly. Both the
Teaching only group’s and the Combined group’s self-esteem increased
from baseline to post-test but analysis showed this increase was not
significant. Those children in the Waiting group showed a decrease in
their level of self-esteem but this proved not to be significant.
The Interaction between self-esteem and Reading Improvement.
We had thought that we would find a
relationship between improved reading and improved self-esteem – that
children who improved in reading would feel more positive about
themselves. Such a pattern did emerge, but not in a
straightforward way. To our surprise, we found that the children
in the Teaching group who began with low self esteem improved more in
reading than those who began with high self esteem. One
might have predicted the opposite: those with more positive beliefs
about their abilities would make greater gains. It was less of a
surprise that those with low self esteem also improved more in self
esteem, but this may partly be due to methodological factors.
Overall the results are consistent with a view expressed by
practitioners that children will respond best to individual teaching
when they have accepted that they have a need for it. A more
positive way of putting this is that children's feelings about
their difficulties should be taken into account when deciding on the
optimum time to provide support.
Literacy Difficulties as a Barrier to Curriculum Access
We were interested to investigate in
what ways literacy difficulties might prevent children from taking part
fully in class activities. This was done by observing a sample of
children who were part of the SPELLIT research project in their
classrooms. |
