The purpose of the current study is to investigate the roles preferred by science teachers in the teaching of socioscientific issues (SSIs) in relation to the communicative approach and discourse patterns in the context of SSI and non-SSI. In this qualitative study, the holistic multiple case study design was used. The study group consisted of…

Understanding the general ideas and methods of detecting molecular structures is essential in high school chemistry. However, there is a need for more practical activities in teaching. A hands-on activity was designed in this study, which uses flexible foam balls and long sticks such as knitting needles to imitate how scientists construct the 3D…

Many students find introductory general chemistry courses difficult because they feel alienated by traditional approaches to teaching and learning. This can become particularly problematic in laboratory sessions where students simply follow processes and procedures that students can view as being mundane and lacking creativity. Contextualised…

There is a lack of knowledge regarding the self-described pedagogical approaches taken by science teachers in Catholic schools regarding the integration of a Catholic worldview in their science classroom. The research team distributed surveys to K-12 Catholic school administrators throughout the Midwest who subsequently distributed…

Measurement uncertainty is a key topic in the university physics laboratory curriculum. In this study, we investigate students' ability to draw conclusions from measurement data and reasoning about measurement uncertainty in inquiry labs. This investigation centres around a task where students conclude whether measurements from two experiments…

This paper reports the quantification of Ca, Mg, and Fe as micronutrients in different vegetables (spinach, sugar beets, and carrots) from raw and processed samples. Simple extraction procedures, titrations, and spectrophotometric analysis were used to determine the amounts of micronutrients before and after cooking. From the obtained results, an…

Newton's laws are a ubiquitous topic in introductory physics instruction. One common problem involves asking what will happen if you stick your finger into a cup of water sitting on a scale. A way to solve the problem would be to first recognize that the water exerts a buoyant force upward on the finger, which students can recognize as being the…

Each year, in middle and high school classrooms, secondary science teachers introduce their students to the periodic table of elements (herein the periodic table). According to the Next Generation Science Standards (NGSS Lead States, 2013), one of the performance expectations states that high school students should be able to, "Use the…

This paper examines how practicing teachers approach and evaluate students' critical thinking processes in science, using the implementation of an online, inquiry-based investigation in middle school classrooms as the context for teachers' observations. Feedback and ratings from three samples of science teachers were analysed to determine how they…

Explaining phenomena associated with a system involves describing a system's structure and articulating the process through which the system's structure changes over time. This paper defines geo-sequential reasoning in the context of plate tectonics and uses it to analyse how students explain the geological processes that occur along convergent…

Cycloadditions in combination with multicomponent reactions are among the most valuable synthetic tools used by organic chemists to construct cyclic and heterocyclic compounds in a straightforward way. Although cycloadditions, such as the Diels--Alder reaction, are mainly covered in basic and advanced organic courses for undergraduate students,…

Silver and its compounds have been widely used in experimental teaching, industrial production, and other fields. In these processes, a large amount of wastewater containing silver is usually produced, which might contribute to environmental pollution. Therefore, recycling silver from wastewater not only has good economic value but also meets the…

Understanding experimental design (e.g. control of variable strategy or CVS) is foundational for scientific reasoning. Previous research has demonstrated that demonstrations with cognitive conflict (e.g. asking students to evaluate and explain different experimental designs) are effective in promoting children's scientific reasoning, however, the…

This paper examines the pedagogical integration of Virtual Microscopes (VMs) in Virtual Learning Environments (VLEs), to identify best practice and improve online pedagogy. It has captured the perspectives of 12 Health and Earth Science university teachers, through in-depth interviews, about the current integration of the VM in online teaching,…
