A Survey on the Student's Consciousness for the Safety in the Heating Manipulations by Adopting the Hazards Drawing -A Study to Promote the Safety Education in the Science Classroom-

Abstract

Although it is well recognized in the science education that the safety education should be promoted in the classroom, these educations have had the tendencies to emphasize the technical operations and/or the knowledges about the experimental tools and the chemical substances. The author has the idea that in the safety education the teacher should instruct the student, more than the technical knowledges, the mental attitude to prevent the accident in the real situations. As a step to realize his idea, the author intended to survey the student's consciousness of the safety for the heating manipulation in the experiments, by adopting the hazards drawing which were developed originally by STEP in UK, but pictured by the author for this survey. The students employed in the survey were selected randomly from elementary to senior high schools (3rd to 12th grade). The total number of the students were 1317. The survey was performed with two objectives. One of them was to know how many hazardous points the student could check in the hazards drawing presented and to know by the questionnaire to what extent the student understood the basic knowledges about the heating manipulation. The other was to examine the usefulness of adopting the hazards drawing in the safety education. The findings of the survey were as follows : (1) The employment of the hazards drawing was very useful in instructing the Safety to the student. (2) The number and the kind of the checked points in the hazards drawing increase rapidly from the 5th grade children and there was no difference between male and female. But there were great differences between individual schools. (3) About sixty percent students even in the 10th grade were apt to fire the Bunsen burner dangerously.
