However, the notion of ‘gifted’ varies between the<br />

three reports that use it to measure ability, as do the<br />

outcomes that emerge from the preferences. Pyryt,<br />

Sandals and Begorya (1998, 76) advised caution about<br />

these patterns since, although differences were found<br />

between gifted students, average ones and students<br />

with <strong>learning</strong> difficulties or disabilities, ‘the magnitude<br />

of group differences is small’. Burns, Johnson and<br />

Gable (1998) found that while statistically significant<br />

differences were found between gifted and average<br />

students, the elements of the LSI associated with<br />

giftedness were different in each study. They concluded<br />

(1998, 280) that ‘it is difficult to accept the idea that<br />

the population of academically able students share<br />

common <strong>learning</strong> <strong>styles</strong> preferences’.<br />

We have attempted to draw from the literature any<br />

instances in which the preferences tend to ‘cluster’,<br />

but the reporting of data has not enabled us to<br />

ascertain the strength of preferences that might<br />

interact with each other. Where scores are reported,<br />

their interpretation appears rather loose. For example,<br />

Gadt-Johnson and Price (2000) reported that tactile<br />

learners in their large sample of over 25,000 children<br />

in grades 5–12 have associated preferences for the<br />

‘kinaesthetic’, ‘auditor y’, ‘intake’, ‘learn in several ways’,<br />

‘less conforming’, ‘teacher motivated’ and ‘parent<br />

motivated’ elements. It is only later in the reporting<br />

of this research that it becomes clear that none of these<br />

‘associated preferences’ was represented by a score<br />

of more than 60 or less than 40; that is, they were not<br />

high or low preferences as defined by the model.<br />

Supporters of the model offer detailed prescriptions<br />

for teaching various types of student: for example,<br />

they report that ‘globals’ appear to need more<br />

encouragement; short, varied tasks (because of their<br />

lower motivation); and when faced with new and difficult<br />

information, it should be interesting, related to their<br />

lives and allow them to become actively involved.<br />

Advice covers individuals and groups, classroom<br />

management, lesson pace, activity, kinaesthetics<br />

and sequencing of material. Advice is related directly<br />

to different types of learner; for example, the idea<br />

that underachievers, ‘at risk’ and dropout students<br />

are almost exclusively tactual/kinaesthetic learners<br />

(see eg Dunn 1990c). Supporters also offer advice<br />

for other preferences. For example, students who learn<br />

better with sound should have music without lyrics<br />

as opposed to melodies with words, while baroque<br />

appears to cause better responsiveness than rock,<br />

and students who prefer light should have soft,<br />

not bright, light. The empirical basis for a distinction<br />

between the effects of different musical genres and<br />

quality of lighting is not given.<br />

There is also detailed advice for developing flexible<br />

and attractive environmental conditions; for example:<br />

Redesign conventional classrooms with cardboard<br />

boxes, bookshelves, and other useable items placed<br />

perpendicular to the walls to make quiet, well-lit<br />

areas and, simultaneously, sections for controlled<br />

interaction and soft lighting. Permit students to work<br />

in chairs, on carpeting, on beanbag chairs, or on<br />

cushions, or seated against the wall, as long as<br />

they pay attention and perform better than they have<br />

previously. Turn the lights off and read in natural<br />

day light with underachievers or whenever the class<br />

becomes restless.<br />

(Dunn 1990b, 229)<br />

Such advice derives from empirical evidence from<br />

studies cited by Dunn as supporting her model<br />

(see Dunn and Griggs 2003).<br />

Several books offer advice through examples of how<br />

particular schools have transformed seating, decor,<br />

classroom planning and timetabling in order to respond<br />

to students’ preferences as expressed through the<br />

LSI (see eg Dunn and Griggs 1988). These offer detailed<br />

‘before and after’ vignettes of schools, their students,<br />

local communities and <strong>learning</strong> environments as well<br />

as ‘The How-to Steps’. In addition, the Dunn, Klavas<br />

and Ingham (1990) Homework prescription software<br />

package is offered to provide ‘a series of directions<br />

for studying and doing homework based on each<br />

individual’s … scores’ (Dunn and Stevenson 1997, 336)<br />

which, it is claimed, increases student achievement<br />

and reduces anxiety (Nelson et al. 1993; Lenehan<br />

et al. 1994). These studies, however, are open to the<br />

criticism that the observed benefits reflect a ‘level of<br />

intervention’ effect rather than a ‘nature of intervention’<br />

effect, since all groups received ‘traditional instruction’<br />

and the most successful group had ‘homework<br />

prescriptions’ as an additional element. This suggests<br />

that success may be attributed to the greatest quantity<br />

of input; the methodological problems of catalytic<br />

validity and the ‘Hawthorne Effect’ are also likely<br />

to play an important part.<br />

Empirical evidence of pedagogical impact<br />

Reporting on a meta-analysis of 36 experimental<br />

studies based on the LSI and PEPS with different<br />

groups of students, Dunn et al. (1995) claimed a mean<br />

effect size equivalent to a mean difference of 0.75 –<br />

described as ‘in the medium to large range’. Of the<br />

36 studies, only six examined the effect sizes of the<br />

Dunn and Dunn model as a whole, while the remaining<br />

30 focused on one of the four sub-areas of the inventory<br />

(environmental, emotional, sociological, physiological).<br />

For example, of the two studies in the emotional<br />

sub-area, Napolitano (1986) focused exclusively on<br />

the ‘need for structure’ element, while White (1981)<br />

looked more broadly at ‘selected elements of emotional<br />

<strong>learning</strong> style’.
