The issue of the secular state is pertinent in Latin America, especially in countries like Brazil, where religion may influence the political and educational field. Data from a survey of biology teachers regarding the teaching of evolution in Argentina, Brazil and Uruguay were analysed, recognising the secularity of the countries. The…

Proteins are essential for cell function, and their biological performance depends on three-dimensional (3D) structures. Insulin is made up of 51 amino acids and is a critical hormone involved in glycaemia regulation. In basic education, concepts involving proteins (synthesis, structure, interactions, and function) are abstract and difficult for…

This study evaluated how the process of teaching scientific methodology occurs in technical courses in integrated high schools. The qualitative case study was conducted through documentary analysis (based on regulations and pedagogical projects) and semi-structured interviews with teachers (n=7), coordinators (n=3), and students (n=16) of the…

This paper aims to introduce the initiative "Escola Sirius para Professores do Ensino Médio" (ESPEM, Sirius School for High School Teachers) hosted by the "Centro Nacional de Pesquisa em Energia e Materiais" (CNPEM, Brazilian Center for Research in Energy and Materials) and supported by the Sociedade Brasileira de Física (SBF,…

The article analyses teachers' learning on the use of multiple representations (MRs) in the teaching of Ohm's law, examining them in a lesson study, structured in 18 meetings of 2.5 hours each, that addressed this physics curricular topic for the 3rd grade of high school. The qualitative research involved four teachers who teach physics in…

1000 Future Scientists (1000FSc) is a university extension project developed at the Department of Chemistry in Federal University of Minas Gerais (UFMG). Conducted by the Higher Education Administrative Technicians and Professors, it presents the university to the community by proposing an engaging experience for elementary and high school…

The purpose of this exploratory study was to investigate Brazilian school teacher attitudes and approaches to biodiversity education. We aim to specifically compare the amount of native biodiversity topics as measured by teachers' reports of their teaching emphasis. The study involved 147 teachers from all geographic regions of the country, who…

In this paper, we present our study into how teaching practices in chemistry are socially stratified under the center-suburban divide in a medium-sized city, located in the State of São Paulo, Brazil. The paper mainly draws upon the Bourdieusian-inspired concepts of institutional habitus and symbolic capital to examine how institutional discourses…

The professional high school by the federal schools in Brazil requires an integrated curriculum itinerary. There is a lack of information about how to achieve that in a practical conception of integration. This article aimed to investigate the interdisciplinary approach of the content "transformation of energy" involving the relationship…

This paper discusses the potential of the creation and analysis of historical networks as didactic strategies in science education. To this end, we first argue the importance of combining critical approaches of the history of science with historical network research. This will be followed by a report of an empirical experiment in which the history…

Harmful plastic debris found on beaches and in the oceans are not limited to drinking straws or bags. There are several synthetic organic polymers that can be used to make different kinds of plastic materials and have resulted in billions of tons of waste that can reach the aquatic biome and are harmful to freshwater and marine communities as well…

The present work is the report of an intern, who through the theme: "Drugs" shows the importance of the use of didactic sequence in the teaching of chemistry for the construction of concepts. The content was applied in classes of the 3rd year of high school, in a public school, in the city of Apucarana - PR. In this sense, the main types…

Recent international documents and educational standards have recommended Science Education be based on three dimensions (Scientific Practices, Crosscutting Concepts, and Disciplinary Core Ideas). This has resulted in an increased interest in research involving Scientific Practices in Science Education. The objectives of this article are to: I)…

Science dissemination or popularization of science refers to the act of facilitating the understanding of research and works of scientific and/or technological origin among the general public. Science dissemination is a relevant issue in the realm of public policy. Considering that in Brazil, the university is responsible for most of the…

Genetics is an area that is increasingly important in people's daily lives. Despite this, its teaching/learning is among the most challenging topics in biology. Several instruments were created over a number of years to ascertain the quality of teaching and learning genetics. In our study, we created a specific instrument to investigate Mendelian…
