Abstract

This study was based upon the survey on the name of 13 basic experimental instruments used in elementary sciene class: Schale, evaporating dish, mortar & pestle, beaker, erlenmeyer flask, spuit(medicine dropper), graduatedcylinder, balance, spatula, dropping bottle, gas collecting bottle, funnel, alcohol burner, and their uses. To implementthis study, an open-ended, written questionnaire was administered to the subjects of in-service elementary schoolteachers, future elementary teachers who have attended at the Gyeongin national university of education, andelementary students in Korea. The findings of this study were as folows: The rates of in-service and pre-serviceelementary school teachers that knew corect name of experimental instruments were not high, the elementary schoolstudent's rates were especially very low. In this study, we found several reasons which they wrote inaccurately: thename to be represented at the textbook that they had studied, the confusion of the name about a fortis pronunciation,wrong expresion in the internet and general book. Al respondents had a wide range of perceptions of uses for theexperimental instruments. Their understanding of uses for evaporating dish, erlenmeyer flask, balance, gas colectingbotle were very poor. And then most of them understood that graduated cylinder, beaker, and erlenmeyer flask weretools to measure the volume of solution or liquid, so they did not exactly distinguish the diference of their uses.
