Diagnostic Testing in Mathematics:" An Extension of die PIAT?

Diagnostic testing in mathematilinvolvesstdentification of

specific strengths and weaknesses in mathematics skill deve),opment

as a basis for subsequent remedial programming. While the assess-

ment of mathematidal skills is relatively clear-cut, there-are'few

diagnostic math`--e-ests available (Salvia & Ysgeldyke, 1978)..

The Key Math Diagnostic Arithmetic Test <Connolly, Nachtmann,

& Pritchett, I/71) is an individually administered test of mathe-èS

grade equivalent total_ test.performance, as well as area,.subtest,

and item performances., The 209 itp.lis,are organized into 14.stibtests

Mons)... Whtile'the Key Math can be used ag a norm-referenced or

criterion-refere+d test, its real value is in its use as a criterion- .

referenced. measure (Salvia & YsseVyke, 1978). Tliis simply means that

one analyzes a child's performance'relative to the specific areas,

.subtests, and/or items that the child :.a.Awered,correctly and in-

cofrectiy. \It is qssume

that such a pfocedure mill enable pattern's

of skill devetopment to be ascertained and remedial programming

attempts to be'facilitated.

The mathematics'subtest of the Peabody Individual Achievement

Test, (FIAT) is a set of 84 questtons desigqed to assess various

levels of arithmetic performance (Dunn & Markwardt, 1970). Age and

grade equivalents and percentile and standard scores are available-

measures of achievement from the FIAT for school-age children. The#

Salvia & Ysseldyke% 1978); the content valttiy was basea on "exten-4

- sive revieasof curriculum materials used,at each grade level," (Dunn -

& Markwardt, 1970, P. 50). The format of the test is multiple-

are arranged in order of Aifflculty with easier items lAcurring in the

to establish the appropriate items for a particular child.I.

that is, the utility of the mathematics.subtest as a diagnostic test

has ngt been demonstrated. However, the problem is not with the con-

Meaningful 6structional objectives based on'the summary information

An analysis of the:itemS of the PIAT mathematics subtest indi-

cates that 14 subgroups of behavioral activities within three main

subsections of mathematical' abilities can be represented. The pro-

posed subgroups wrthin the PLAT mathematics subtest, ,grouped aecord-,

ing tb the three major areas of.abilities, are reported in Table 1.43.

correct- (circled) or incorrect,items (crosselfout).

An e?cample of the use of this matrix in the analysis of the

mathematics Performance of a sixth grade eleven year old child (Chai-les)

,Is presented in Table 6. In following the scoring procedures suggested

in the test manual :.Charles' performance (relative to others in hiv

grade) would be recorded as the following: raw score 45; gra.de equiva-

lent 5.3; percentile 33; standard score 95. The perfoimance would be

interpreted ak slightly below grade level expectancy and similar to 1k.4

or above approximately 33 percent of sixth grade children on whom the.

test was normed. Educational planning from this information is softie-

What limited.

Insert Table.6 about here

/

Perusal of the additiOnal information provided by the error anal-

ysis.matra (see 'Tablt 6) indicated that while Charle's performed more t

than half of the items he attempted (i.e., 17/29), his performance1

was somewhat unevenly distributed according to,the general subsections.

Most of those items attempted (i.e., 80%) within the Foundations area,

were answerV correctly. Of the 73 percent cortedtly answered in theA a

In analyzing the 62 percent incorrect respon4es in tLe ApPlica-

any items involving fractions, geometry. or algebra; he correctly

answered 60 percent.of the questions presented in the subuoup of

NumericaP Kelatiionships, and 50 percent within the subgtoup of Word.

Problems. Those items which were incorrectly answeted dealt with

identification of place values (items 51 drid 54), and completion of

two step word problems (items-49 and 58).

These results suggest that Charles may be having trouble with

pIcIce valuALitems 46, 38, 51, 54), with two-step problem scjving

(items 42, 46, 58), and with beginntng iDlsion using place value.

AdditiOnal informal assessment wOuld be warrapted to determine the

exaCA,naenre of the skills Charles has acquired in these areas. Since

all tests are.merely samples df behavior, it is generally recommended

to attempt to verify suggestive test perfonmance with follow-up

assessments., The results,of such a procedure can help to clearly de-

limit areas in which instruction can be useful..
