摘要

摘要本研究旨在探讨科学实验室学习环境与学生在实验室安全实践之间的显著关系,研究对象为在面对面课堂中至少选修一门带有实验室单元的科目或课程的教育学生。这项研究的数据来自201名教育学生,通过使用谷歌表格进行在线调查收集。采用非实验描述性相关设计,采用人口普查方法选择研究对象,并采用标准化问卷。统计方法采用加权平均值、标准差、Pearson积差相关设计和线性回归分析。研究发现,科学实验室的学习环境处于非常高的水平。同时,学生在实验室安全方面的实践,特别是应急预案、工作流程、化学废弃物管理方面的实践水平很高,在安全设备、实验操作方面的观察水平也很高。结果还显示,科学实验室的学习环境与学生的实验室安全实践有显著的关系。在科学实验室学习环境中,对学生实践有显著预测作用的是物质环境。结果显示,大学可提供并维持一个有利的实验室学习环境,这对学生执行实验室安全、加强实验处理和升级科学实验室的安全设备至关重要。

Science Laboratory Learning Environment and Students’ Practices on Laboratory Safety
This paper aims to identify the significant relationship between the science laboratory learning environment and students’ practices on laboratory safety for education students who took at least one subject or course with laboratory unit in face-to-face classes. The data from this study came from 201 education students, collected through an online survey using Google Forms. The non-experimental descriptive correlational design, census approach was used to select the study participants, and standardised questionnaires were also utilised. The weighted mean, standard deviation, Pearson product-moment correlation design, and linear regression analysis were employed as statistical techniques. The study found that the science laboratory learning environment is at a very high level. Meanwhile, the students’ practices on laboratory safety, especially emergency response plans, work procedures, and chemical waste management, are at a very high level, while safety equipment and handling of experiments are observed at a high level. The results also showed a significant relationship between the science laboratory learning environment and students’ practices on laboratory safety. The domain of science laboratory learning environment that significantly predicts students’ practices is the material environment. The result implied that the institution may provide and maintain a conducive laboratory learning environment, which is essential for students to perform laboratory safety, enhance the handling of experiments, and upgrade the safety equipment in the science laboratory.
