Abstract


The purpose of this study was to investigate the level of Omani chemistry students' understanding of safety precautions in chemical laboratories. The sample of the study included (54) 4th year chemistry students from colleges of education in Oman. (22) of them were males; whereas (32) were females. An instrument has been used to tackle the problem of the study which is a test measuring the understanding level of safety precautions, and consisted of (55) items distributed into (5) domains.
The results revealed from the study were as follows:
1. The students’ understanding level of safety precaution was lower than the educationally accepted criterion.
2. There is no significant difference in students’ average performance on the safety precautions whole test and its sub-domains with respect to gender.
3. There is no significant difference in students’ average performance on the safety precautions in the whole test and its sub-domains with respect to the previous chemical achievement level (except for the second domain), in favor of the achievement level (over good).
The researchers then recommended implicating an instructional unit for safety precautions in chemistry and including such precautions as part of the regular practical exams. The researchers also recommended conducting further studies in the field of safety precautions in laboratories at the different stages of studying.
