An inquiry-based laboratory activity to determine the chemical composition of a component in alkaline detergents, sodium sesquicarbonate (SSC), is proposed. On the basis of introductory demonstrations by the instructor on the chemical properties and reactions of SSC, students propose the hypothetical composition of SSC and possible quantitative…

Modeling is a core scientific practice. This study probed the meta-modeling knowledge (MMK) of high school students who study science but had not had any explicit prior exposure to modeling as part of their formal schooling. Our goals were to (A) evaluate the degree to which MMK is dependent on content knowledge and (B) assess whether the upper…

The aim of this study is to investigate Emiratii high school students' understandings of stoichiometry, their use of metacognitive strategies, and the influence of students' use of metacognitive strategies on their understandings of stoichiometry.

Currently not many people would doubt that computers play an essential role in both public and private life in many countries. However, somewhat surprisingly, evidence of computer use is difficult to find in German state schools although other countries have managed to implement computer-based teaching and learning in their schools. This paper…

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…

In accordance with the requirements for the National Curriculum Statement for both Life sciences and Physical sciences and the importance of community engagement in Higher Education in South Africa, this paper described the use of the lecture-demonstration "A Pollutant's Tale" to create climate change awareness amongst school learners.…

The council of the American Association for the Advancement of Science, at its Cincinnati, Ohio meeting in December, 1923, authorized a special committee to make a study of the role played and to be played by science in education. That committee was organized in 1924, and the presentation of this bibliography is a product of its work. An adequate…

This paper investigates the educational role of museums of chemistry in presenting chemistry to the public in Italy, particularly to students. The activities carried out by Italian museums and scientific collections completely dedicated to chemistry have been analyzed, focusing on the relationship between these institutions and students with…
