The purpose of this study is forming concept model and measurement modal and congirming validity of attention test instrument based on them. For this sake, concept model and measurement model which are applicable to Korean educational situation were set up by means of analyzing and unifying papers and proceeding studies concerning attention were operated and attention test instrument was made as a measurement tool.
In this study, attention was divided into selective attention and lasting attention according to the aspect of concept and they were divided into seeing and hearing to measure respectively. As a result, measurement variables were set up in the form of determining colors, listening and answering in selective attention, and listening and finding in lasting attention, and the last items were selected 3 factors including 49 items.
The preliminary test with 32 elementary school student of a class in Seoul by devised tool was performed to confim goodness and to estimate required time. Items unfit for Total-item correlation from collected data were eliminated through ithem analyzing process. And dimensions and items having low a coefficient were ignored through calculating Cronbach-a coefficient against lower dimension of tools respectively so that higher reliance was obtained. Also required time was estimated. After these assortment, 3 factors with2 5 items was consisted as an attention test instrument of children in this study.
With the devised tool, investigation was performed with 141 children of 2nd year elementary school students on May 6 and 7, 1998 in Pusan.
Followings are summarized results of this study.
1. Cronbach-a coefficient was reckoned according to total-item correlation and sub-tests. Items with negative correlation and those which can make reliability higher were eliminated. For sub-tests, guessed range of Cronbach-a coefficient was from .4661 to .8953 and that means this instrument was verified reliable comparatively.
2. In Factor analysis to verify validity, correlation matrix was produced by masuring correlation with sub-tests. Total items was Varimax Rotated after setting factor number 3 and then items having lower factor loading from each factors than .30 was eliminated. In three sub-scales, factor loading of almost items were over .20~.30, which means each items have meaning independence. Results of Factor analysis and reliance verifying showed reliability of the nstrument with totally higher reliability(.7897-.7971)
3. With calculating attention score and hyperactivity score as sub-scales in ADHD(Comprehensive Teacher Ratign Scale: ACTeRS) and correlation coefficient of total score and sub-tests, correlation of 3 sub-tests and attention score was roughly meaningless, and reliability of this instrument score was roughly meaningless, and reliability of this instrument was proved because of meaningful correlation between total test scroe an attention score.
On the basis of experimental validity verification procedure through concept model, following results are obtained in the aspect of theory, methodology, and practice.
1. This study formed experimental research model based on theatrical frameworks concerning attention in theoretical aspect. Also it was meaningful that possibility of development of measurement instrument which can test attention of children was suggested through experimental research procedure.
2. In considering procedure of validity of the instrument, methodological meaning was resulted. Experimental verification in this study performed through validity and concurrent validity process with reliability and validity. After the assortment using cronbach-a coefficient as a reliability verification method, analysis as meanig of items by factor analyzing, and Varimax Rotation, ndependence of items was affirmed according to dimensions.
3. In aspect of practice, this study was meaningful because of manufacturing and validity of instrument which can be used to test attention deficit disorder with hyperactivity or children of learning - hindrance, attetion is critical so that it is meaningful economically that there is test in group easily with considering many but person by person test instrument.
