高校实验室安全状况对学生、教师和学校都有很大影响。对高校化学实验室安全风险评估有助于加强实验室管理,减少安全隐患的发生,充分发挥实验室的科研和教学功能。通过分析目前常用的实验室安全评估方法,发现其对高校化学实验室安全风险评估并不合适。针对高校化学实验室安全隐患的问题,,将量规评价法应用于安全风险评估,设计出适合高校化学实验室安全风险评估的量规表。以江苏师范大学各化学实验室为例,利用该评价量表进行化学实验室安全风险评估,并对评估结果进行分析,总结其存在的安全隐患问题。最后讨论量规法应用于高校化学实验室安全风险评估的优势。 相似文献

化学是一门实践学科,实验室是化学学科重要的教学资源,化学实验教学能否顺利高效进行,化学实验室的建设、发展与应用就是其物质基础和基本保证。实验室的建设离不开硬件软件的建设,硬件即教室的建设、实验家具的配置、实验仪器药品的配置;软件即实验室管理人员的组成、实验室相关规章制度的完善和执行。 相似文献

The purpose of this quantitative study was to examine the interaction effect between grade level and gender with respect to
students' attitudes toward chemistry lessons taught in secondary schools. The sample consisted of 954 chemistry students in
grades Secondary 4–7 (approximately 16–19 years of age) in Hong Kong. Students' attitudes were surveyed using an attitude
toward chemistry lessons scale (ATCLS), and subscale scores were produced on four dimensions: liking for chemistry theory
lessons; liking for chemistry laboratory work; evaluative beliefs about school chemistry; and behavioral tendencies to learn
chemistry. When the ATCLS data were subjected to two-way MANOVA, the interaction effect between grade level and gender on
students' attitudes toward chemistry lessons was statistically significant. The interaction effect was attributable to scores
on the theory lessons subscale and laboratory work subscale. Male students in Secondary 4 and 5 liked chemistry theory lessons
more than their female counterparts. However, male students' liking for chemistry laboratory work declined when they progressed
from Secondary 4 to Secondary 7; no such a significant decline in attitude toward chemistry laboratory work was found in females.
Overall, both males and females were just marginally positive about chemistry lessons during the years of secondary schooling.
Implications of these findings for curriculum design are discussed. 相似文献

This study examined the influence of selected factors on students' performance in practical chemistry. Twelve factors were extracted by principal component analysis. These factors accounted for 64% of the variance of the scores in practical chemistry when stepwise multiple regression analysis was applied on the data. Students' participation in laboratory activities made the greatest independent contribution to the variance in performance (0.16), followed by students' attitude to chemistry as a subject (0.11), teachers attitude to chemistry laboratory work (0.10), and availability of chemistry laboratory materials (0.08). School location, sex of the student, and students' fear of explosion and of damaging expensive equipment made nonsignificant contributions. The implications of the findings of the study for instruction in chemistry are discussed. 相似文献

This study investigated the chemistry laboratory classroom environment, teacher–student interactions and student attitudes
towards chemistry among 497 gifted and non-gifted secondary-school students in Singapore. The data were collected using the
35-item Chemistry Laboratory Environment Inventory (CLEI), the 48-item Questionnaire on Teacher Interaction (QTI) and the
30-item Questionnaire on Chemistry-Related Attitudes (QOCRA). Results supported the validity and reliability of the CLEI and
QTI for this sample. Stream (gifted versus non-gifted) and gender differences were found in actual and preferred chemistry
laboratory classroom environments and teacher–student interactions. Some statistically significant associations of modest
magnitude were found between students' attitudes towards chemistry and both the laboratory classroom environment and the interpersonal
behaviour of chemistry teachers. Suggestions for improving chemistry laboratory classroom environments and the teacher–student
interactions for gifted students are provided. 相似文献
