There is a scarcity of studies that focus on how South African high school physical sciences teachers are grappling with chemical laboratory safety (CLS). This is despite the fact that the Curriculum and Assessment Policy Statements in the South African school system increased emphasis on laboratory activities in the physical sciences. Department…

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…

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…

We examined the effects of applying the instructional method of constructive controversy in an animal welfare unit, on middle-school students' knowledge and attitudes relating to the treatment and welfare of animals. Accordingly, we developed and implemented a four-stage instructional model centring on constructive controversy in a class of 27…

Inquiry-based learning can be an effective approach when students are provided with sufficient guidance. However, there is an ongoing debate among practitioners about the nature, type, and level of such guidance. This study investigated the effects on middle school students' (N = 116) conceptual knowledge and inquiry skills acquisition of…

The formation of chemistry identities among students is closely linked to the norms and practices prevalent in their chemistry learning environments. However, these norms may not be equally accessible or aligned with formal assessment criteria, leading to disparities for students in cultivating a positive chemistry identity. This study…

Many high school students learn about nutrient cycling during biology, environmental science, and agriculture classes. These lessons often focus on soil and plants, and nutrient cycling is usually taught independently from climate change. Scientists know that animals, including fish, can have strong effects on nutrient cycling (i.e., nitrogen and…

Instructional technology has been developing rapidly and its impacts can be observed in learning environments. One of the recent technological tools used in science classes is virtual laboratories. This study aims to investigate the effects of virtual laboratories on developing gifted students' conceptual knowledge and improving science process…

To be able to design a laboratory course it is important to know what laboratory skills students possess before the course starts. This way the course can focus on developing skills in areas that are lacking. Despite the extensive literature on laboratory education, there are few studies on what laboratory skills students have at this stage of…

This study investigated student's knowledge and understanding of mechanical stress including strain, and the relation between mechanical stress and strain, using material created by the authors of this text. It also investigated what the students perceived helpful for learning. The material was a complete laboratory setup and was intended to be…

The Center for Anatomy and Physiology Education has hosted interactive human cadaver laboratory tours for local high schools (ages 14-18) and undergraduate university students since 2014 to expose students to healthcare careers. Students receive information on the history of body donation and healthcare careers and observe human anatomy on…

Oftentimes the increase in industrial development is the cause of environmental problems. Environmental problems can be overcome by the presence of humans who care about the environment or have environmental literacy skills. Environmental literacy skills can be instilled from an early age, for example through practicum learning in schools.…

In this paper, we examined teachers' understanding of electrical concepts such as power, current and potential difference based on how these concepts were applied to understand the relative brightness seen in bulbs of different wattage under different connections--series or parallel. From the responses of teachers to a concept question, we…

This research aims to develop an instructional model using advanced laboratory equipment (ALE) based on collective intelligence attributes that can be applied to the scientifically-gifted students. The developed GI-ALE model is defined by introducing the principles of the group investigation (GI) model to the existing ALE instructional model based…

Some science subjects are often perceived to be difficult and boring by students due to their nature and the way they are taught. This study sought to check the effectiveness of the technology-enhanced instruction method with comprehensive use of virtual labs and animations in teaching nerve cells' (neurons and glial cells) structures and…
