Chemical safety management is an iterative process where reviews of safety deficiencies (e.g., inspection notes) and failures (e.g., injuries) guide improvement efforts. The present work investigates safety in the school chemistry laboratory through two substudies. First, we interviewed 10 Swedish middle and high school chemistry teachers about…

The synthesis of alkenes using the Wittig reaction is a traditional part of many undergraduate organic chemistry teaching laboratory curricula. The aqueous medium version of the Wittig reaction presented is a reliable adaptation of this alkene formation reaction as a very safe alternative in the introductory organic chemistry laboratory. The…

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…

In this article we summarise over 60 reports and research articles on pre-laboratory activities in higher education chemistry. In the first section of the review, we categorise these activities as follows. First are those intending to introduce chemical concepts, that typically take the form of a pre-laboratory lecture, pre-laboratory quizzes, and…

The effectiveness of traditional face-to-face labs versus non-traditional online, remote, or distance labs is difficult to assess due to the lack of continuity in the literature between terminology, standard evaluation metrics, and the use of a wide variety non-traditional laboratory experience for online courses. This narrative review presents a…

This study aimed to find out the situation of physical condition of labs, equipment in labs, and use of labs during instruction, and problems faced by science teachers in conducting practicals. A questionnaire for science teachers was used as a tool of research. Eighty (80) schools from four districts of administrative division Gujranwala of…

Agricultural mechanics laboratory management skills are essential for school-based agriculture teachers who instruct students in an agricultural mechanics laboratory (Bear & Hoerner, 1986). McKim and Saucier (2011) suggested the frequency and severity of accidents that occur in these laboratories can be reduced when these facilities are…

Raman spectroscopy is a powerful experimental technique, yet it is often missing from the undergraduate physical chemistry laboratory curriculum. Tetrachloromethane (CCl[subscript 4]) is the ideal molecule for an introductory vibrational spectroscopy experiment and the symmetric stretch vibration contains fine structure due to isotopic variations…

The aim of this study was to determine science and technology teachers' views about the causes of the problems encountered in laboratories. In this research, phenomenology, a qualitative research design, was used. 21 science and technology teachers who were working in elementary schools in Eskisehir during the 2010-2011 spring semester were the…

This research is a developmental study of Engineering Laboratory Management indicators. It is formed to assess the level of quality management of the polytechnic level laboratory. The purpose of indicators is to help provide input into the management process of an engineering laboratory. Effectiveness of teaching and learning at technical…

This study examined the effects of integrating instructional materials in Facebook on students' awareness and practice of laboratory safety. A quasi-experimental pretest-posttest two-group design was used in the study. The results indicate: 1.) The exposure to (Online Social Networking-Based Health Education) OSNBHE can improve students' awareness…

Skills needed to manage a laboratory are essential knowledge for all school-based, agriculture teachers who instruct agricultural mechanics curriculum (Saucier, Terry, & Schumacher, 2009). This research investigated the professional development needs of Texas agricultural education student teachers regarding agricultural mechanics laboratory…

Accidents happen; however, the likelihood of accidents occurring in the agricultural mechanics laboratory is greatly reduced when agricultural mechanics laboratory facilities are managed by secondary agriculture teachers who are competent and knowledgeable. This study investigated the agricultural mechanics laboratory management in-service needs…

In this study the Delphi technique has been used to develop a list of educational competencies for preparing secondary agricultural education instructors to effectively manage their school greenhouse facilities. The use of specialized facilities in agricultural education requires appropriate preparation of agricultural education teachers. The…
