The long and complex history to define the composition of water as H[subscript 2]O is summarized. This case study could be useful not only to introduce the history of chemistry in the classroom but also to teach the basic tenets of the nature of science (NOS). Water has been present in several turning points in the history of chemistry such as the…

Ambient ionization mass spectrometry enables rapid in-situ analysis of a plethora of analytes that are relevant to the forensic and defense communities. As the arsenal of ambient ionization techniques, aimed at solving specific targeted problems, continues to expand, the adoption of these techniques into non-academic settings has been relatively…

This qualitative case study delved into students' understanding and positioning while they participated in solving an authentic, conceptually-based problem in a high-school chemistry class. Verbal and nonverbal cues, particularly gestures, offered broader awareness of students' engagement in sensemaking during the learning experience. The…

Background: Science skills play a crucial role in fostering economic development and technological innovation, making the enhancement of science education a global priority. Despite the recognized importance of teacher practices in enhancing equitable and effective learning, much of the research on their impact on student outcomes has been…

Understanding nature of science (NOS) is a fundamental goal in science education standards. Due to the role of specialised and educational teachers' preparation programmes in developing their NOS concepts, this study aims to identify views on NOS and attitudes toward teaching NOS among Saudi undergraduate chemistry students and the differences…

A widespread call has been made to develop and support more integrated approaches to STEM education. The first law of thermodynamics serves as a guiding principle for the crosscutting concept of energy and matter. A qualitative interview study was undertaken to support integrated approaches to STEM education by exploring how chemistry, physics,…

Are the ways of engaging with the world that students develop through higher education particular to bodies of knowledge they study? In this article, we examine how students' accounts of the discipline of chemistry in England and South Africa changed over the three years of their undergraduate degrees. Based on a longitudinal phenomenographic…

In the future, learning will be essentially characterized by the ability to regulate the learning process and monitor success independently from a teacher. The technical possibilities offer better access to learning contents, precise and more individualized feedback, and learning phases adapted precisely to the needs of the learner in terms of…

General chemistry is a foundational course that most STEM students are required to take at some point in their academic careers, as such, thousands of students find themselves in a chemistry classroom every year. Students come into the classroom not only from different academic backgrounds but also from a variety of social and emotional…

Physical experiments on real-world systems are proposed as a means to raise learning outcomes and Arduino microcontroller is highlighted as an appropriate tool to perform them. However, experimentation on a real system may encounter various barriers. Therefore, a learning environment was developed in order to perform Arduino experiments on digital…

A little studied aspect of supporting students in large introductory STEM courses is examining from whom students seek information and advice when they are struggling in or need advice about issues related to large introductory courses. The current study explores student support-seeking behavior related to academic issues or concerns in their…

During the pandemic caused by SARS-CoV-2 (COVID-19), a paper analytical device (PAD) was proposed as a tool for remote laboratory classes for undergraduate chemistry to teach calibration curve concepts. For this experiment, students were taught how to prepare a PAD, calibrate standard solutions, construct a calibration curve, and treat data…

The mining industry in Brazil, despite contributing to economic growth, is one of the human activities that negatively impacts the environment. This situation can be contextualized in discussions of several curricular chemistry topics. One way in which science, technology, society, and environmental issues can be discussed in classes is through…

The ability to communicate scientific concepts to expert and nonexpert audiences is an essential skill for chemistry and STEM students. Current chemistry curricula mainly focus on developing skills to communicate technical information to expert audiences, while relaying the same information to general audiences receives much less attention.…

This study's general theme revolves around practical work in chemical education, and its scope is the employment of a novel inquiry strategy combined with a new openness level. We investigate how the controlled positive error, a new device for inquiry activities developed by us, affects undergraduate students' experience of an experiment and…
