Comprehensive curricula are described for middle and high school classrooms built around the synthesis of biodegradable calcium alginate capsules prepared from food-safe chemicals. Experiments and activities question whether calcium alginate capsules are a viable alternative to single-use water bottles and consider what characteristics are…

This article presents a case study of "the aspirin unit," a curriculum unit from an advanced chemistry class in a neighborhood high school in a large US city. The extended case method is applied to analyze this curriculum within the larger US political context that criminalizes youth of color. Data sources include retrospective…

As part of a revision to the content and delivery of first-year chemistry instruction at the University of British Columbia's Okanagan campus, we have employed the United Nations Sustainable Development Goals (UN SDGs) as a thematic framework. This framework was introduced to promote the achievement of affective learning outcomes, including a…

There is an ongoing discussion about what content that should be taught in science education and there are different views among teachers about what represent good science content. However, teachers are not isolated individuals making their own interpretations, but are part of institutionalised systems building on patterns in the selection of…

Studies of the philosophy of chemistry over the past 15 years suggest that chemistry is a hybrid science which mixes scientific pursuits with technological applications. Dominant universal characterizations of the nature of science thus fail to capture the essence of the discipline. The central goal of this position paper is to encourage…

"Proceedings of International Conference on Education in Mathematics, Science and Technology" includes full papers presented at the International Conference on Education in Mathematics, Science and Technology (ICEMST) which took place on May 18-21, 2023 in Cappadocia, Turkey. The aim of the conference is to offer opportunities to share…

The aim of this study was to assess how the different aspects of nature of science (NOS) were represented in Finnish and Swedish upper secondary school chemistry textbooks. The dimensions of NOS were analyzed from five popular chemistry textbook series. The study provides a quantitative method for analysis of representations of NOS in chemistry…

This paper scrutinizes the contribution of Romulo de Carvalho to the development of the Portuguese science curriculum, arguing that it was critically informed by his lifetime inclination to the humanities. It focuses on a particular historical event: the 1948 chemistry programme for the secondary school "Liceus". The paper briefly…

We describe the modifications to an instrumental analysis course which incorporated the link between science and public policy. This course combines classroom lectures, project based labs, and a writing assignment. The project based labs have a focus on health and environmental issues directly involving the local community, while the writing…

Based on the best-selling book "The Parallel Curriculum", this professional development resource gives multifaceted examples of rigorous learning opportunities for science students in Grades 6-12. The four sample units revolve around genetics, the convergence of science and society, the integration of language arts and biology, and the periodic…

This study explored the impact of using a socioscientific issue (SSI) based curriculum on developing science content knowledge. Using a multi-level assessment design, student content knowledge gains were measured before and after implementation of a three-week unit on global warming (a prominent SSI) that explored both the relevant science content…

Presented are two brief articles related to teaching the history of chemistry in college chemistry, "Utilizing a Historical Perspective in the Teaching of Chemistry" (Joseph W. Kamsar), and "History of Chemistry" (George B. Kauffman). (RH)

Illustrates the basis of carbonless paper using sketches and examines the components of this kind of paper in detail. Discusses important chemical considerations and focuses on microencapsulation of the dye precursor and the reagent layer. (DDR)

Focuses on the kidnapping of a child whose fingerprints were not found inside the crime vehicle. Discusses the investigation that followed and led to knowledge of the differences between the fingerprints of children and adults. (DDR)

Describes two high school courses, "Chemistry of Technology (Chem Tech)" and "Physics of Technology (Physics Tech)," that emphasize multidisciplinary learning through applicative, hands-on activities. Provides course descriptions, lists the advantages of using a unified science-technology model, and discusses limitations of…
