Pre-service teachers who conduct experiments are faced with various risks in terms of physical, health and environment due to the chemicals they are exposed to in the laboratory classes. Working in a laboratory without knowing these risks causes accidents such as chemical spills, explosions and fires, and even individual injuries. For this reason,…

When laboratory accidents in schools, especially in recent years, are examined, it is remarkable that many of these events resulted from the incorrect implementation of laboratory safety. The most significant role in the administration of laboratory safety belongs to science teachers. During this process, the necessity of laboratory safety…

Laboratory studies are very important for science education but also involve various risks. It is possible to minimize these risks by providing a safe working environment. This study aims to determine the knowledge and views of secondary school students on laboratory safety and to identify their deficiencies in this regard. The survey method was…

This study explores the effect of video-based instruction on the safety rules in the chemistry laboratory on student achievement. The sample for the study comprised 61 ninth grade students enrolled in two different classes at a public high school. The students in the class designated as the experimental group (N = 32) were given video-based…

Open-ended and inquiry-based experiments will make students more active in the learning environment, and so they play an active role in solving the problem. So, it is expected that especially classroom teachers will be more active in the laboratory environment. In this context, opinions of the classroom teachers about the science laboratory…

Activities carried out in the laboratory provide important contributions to students in terms of developing their research, problem solving, questioning, using hand skills and communication skills. However, providing safety during the studies in the laboratory environment is extremely important. The aim of this study is to determine information…

The purpose of this paper is to develop a "valid and reliable laboratory safety questionnaire" which could be used to identify science teachers' understanding about laboratory safety issues during their science laboratory activities. The questionnaire was developed from a literature review and prior instruments developed on laboratory…

One of the prerequisites for chemistry teacher candidates is to demonstrate certain laboratory skills. This article aims to determine and discuss the competencies of pre-service chemistry teachers in a chemistry laboratory context working with solution chemistry content. The participants in this study consisted of a group of pre-service chemistry…
