A survey was developed and implemented to determine how pervasively safety principles and cultural expectations are included in the chemistry curriculum at the undergraduate level. The survey was completed by first-year doctoral candidates in the chemical/pharmaceutical sciences. A majority of the respondents were trained in the use of Safety Data…

Lakes are artists' pigments made from colorants bound to an inert substrate, usually hydrated aluminum oxide. Before the late 19th century, lakes were made from natural pigments extracted from plants and insects, extracted either directly from the dyestuff or indirectly from waste materials generated in the manufacture of dyed textiles. The first…

In this article, we discuss the replication of a forgotten chemical instrument in the context of undergraduate chemistry education. Together with students, we have attempted to replicate an eighteenth century "eudiometrical" procedure. Eudiometry was the practice of measuring the "goodness" of the air by looking at the volume…

It is a controversial issue in education that students perform dissection experiments. Different opinions have been noted in studies on this subject, and various applications are recommended according to education levels. This case study aimed to determine pre-service science teachers' views of hands-on dissection and virtual dissection. The study…

Based on four types of laboratory safety questions (chemical, biological, physical, and medical), a cross-sectional survey of students at Kunming University of Science and Technology (China) was carried out to determine the awareness of laboratory safety among university students. The survey was completed by 335 students in total, with a response…

Hands-on dissections of animals are traditionally regarded as an essential part of biology education. Nowadays, regardless of the reported educational benefits, there is a gradual change in the concept and acceptance of hands-on dissection, leading in many cases to its abandonment in schools and its replacement with alternatives such as 3D models,…

A new module designed to ease the transition from school to university was devised and implemented at Cardiff University School of Chemistry. Two iterations of the module are described, both of them conducted under restrictions imposed by COVID-19 pandemic regulations. Over a two-week period, students attended 15 different sessions, each designed…

Animal dissection is practiced to varying degrees around the world and is particularly prevalent in North America throughout all levels of education. However, a growing number of studies suggest that nonanimal teaching methods (NAMs) (e.g., virtual anatomy tools and three-dimensional models) are better for achieving learning goals compared to…

Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…

Recognising effects of care departs from previous conceptions of care within science education as an idealised, ethical, and normative dimension of being, thinking and relating. In this article, we hesitate with care's moralistic qualities to render visible disruptive and complicit moments of care in complex ethical and political situated…

Students in environmental sciences, ecology, or wildlife management are often reluctant to acquire training in basic laboratory techniques. To advocate the importance of this training, we reviewed literature in the fields of biological and environmental science for one frequently used technique--centrifugation--and evaluated whether centrifugation…

The aim of this study was to determine the attitudes towards laboratory skills and chemistry laboratory anxieties of pre-service science teachers who were currently registered to general chemistry laboratory course and who had taken this course previously. To evaluate candidates' attitudes and anxieties in line with this purpose, they were…

Laboratories are an indispensable part of the fundamental sciences. Laboratories are important learning environments that enable students to relate events to daily life as well as being places where theoretical knowledge is implemented. The present study investigated the knowledge and usage level of preservice biology teachers regarding lab…

Course-based Undergraduate Research Experiences (CUREs) have been described in a range of educational contexts. Although various learning objectives, termed anticipated learning outcomes (ALOs) in this project, have been proposed, processes for identifying them may not be rigorous or well-documented, which can lead to inappropriate assessment and…

Due to the COVID-19 pandemic, in-person undergraduate chemistry laboratories at North Carolina State University were not available to students during the 2020-2021 academic year and were replaced with online laboratories. With the return to in-person laboratories in the fall semester of 2021, there was widespread concern among the faculty that…
