Article
Full-text available
Major events, such as pandemics and war, generate great public interest in science, as in the current moment in which we live. We argue, however, that this interest operates through historical pulses and that it does not lead to an increase in scientific literacy in society in general and even among the scientists themselves.
Article
Full-text available
It has been proposed that ecological theory develops in a pragmatic way. This implies that ecologists are free to decide what, from the knowledge available to them, they will use to build models and learn about phenomena. Because in fields that develop pragmatically knowledge generation is based on the decisions of individuals and not on a set of p...
Conference Paper
Full-text available
In this study, we start from the idea that the historical contextualization of scientific racism, from a Science, Technology, Society and Environment (STS) educational approach, makes it possible to address, in the classroom, current scientific discourses and practices potentially stigmatizing for certain human groups. It happens, for example, with...

Article
Full-text available
It has been shown that many people do not understand how scientific knowledge is built and accepted, even after scientific education. One way to deal with this problem is through teaching about the Nature of Science (NOS). NOS can be understood as a pedagogical construct aiming to foster the understanding of the main characteristics of scientific w...
Article
Full-text available
Despite the importance of evolution to understand living phenomena, evolution teaching confronts several tensions, especially with respect to teachers’ and students’ religious beliefs. These aspects have been widely investigated in the USA and Europe. However, little empirical research has been done on this issue in Latin America, despite their lar...

O presente estudo foi desenvolvido no curso de Engenharia de Pesca da Universidade do Estado da Bahia (UNEB),...
Article
Ecology has received many criticisms concerning its theoretical maturity, often on the grounds that it lacks laws and, therefore, a clear and unified theoretical background. We argue that the search for laws to understand ecological theory was prompted by the (perhaps inadvertent) adoption of an axiomatic perspective that traces back to syntactic a...
Article
Full-text available
Background: Understanding patterns in traditional plant use knowledge is crucial for assisting policy making with regard to nature conservation, human nutrition, human health, as well as educational and participatory processes in traditional communities. We aim to document and describe local ethnobotanical knowledge and test the hypothesis that gen...
Chapter
Belief in genetic determinism (BGD) may be defined as ascribing more causal power to genes in the formation of traits than available scientific knowledge suggests (i.e., genetic overattribution). BGD is an educational challenge because it is both at odds with scientific knowledge and connected to a number of societal challenges. It remains unclear...

Chapter
Since 2011 we have been developing a participatory problem-based learning (PBL) methodology to teach about the nature of science (NOS) and, also, to foster the development of some practical and attitudinal dimensions of scientific practice. This methodology entails a participatory knowledge-centered approach where the teacher plays a key mediating...
Article
Full-text available
The excess of curriculum content is a well-known problem in high school biology. Some strategies to adjust the amount of content to the available classroom time have been proposed, but none has been widely accepted and applied. Furthermore, biology is frequently presented in high school not as an integrated science, but as a collection of unrelated...
Article
To understand and act upon a complex reality like COVID19, we need to integrate knowledge from different academic sciences, in interdisciplinary efforts, and academic knowledge and other knowledge systems, in transdisciplinary processes. Without an integrated view leading to socially robust orientations, we are less likely to successfully navigate...
Article
Full-text available
Many problems we face today, including sustainability issues, are complex and encompass intertwined systems. As such, they are difficult to understand and define due to the pluralism of values within society, which also makes it hard to reach agreement on these issues. Technocratic solutions then may be perceived as improper by stakeholders, detach...
Chapter
Full-text available
We address in this chapter the problem of how the transition from a physicochemical to a life-constrained world occurred. We assume an organizational view of ecological systems, according to which this transition can be conceptualized in terms of the passage from a closure of processes to a closure of constraints in the ecological realm. This persp...
Chapter
This chapter comments on the book from the perspective of the developments in philosophy of science and intercultural communication. It raises a number of issues to be further discussed in order to continue inquiry into Tateo’s approach. It discusses how imaginative processes are engaged in modeling work in science. It also shows how, facing the en...
Article
High levels of sociality in spiders interact with morphological traits that enhance dispersal and dispersal propensity. The social spider Anelosimus eximius occurs in tropical rainforests in South America, including in the north and mid-west Amazon, and we have recently found records of its presence in Atlantic Forest, even though the arid features...
Preprint
In fields of study that develop axiomatically, theoretical syntheses have the role to describe which are these axioms and how scientific practice should be guided by them. However ecology develops pragmatically, that is, scientists propose new understandings of the world by exploring, modifying and coopting previously proposed models, seldom referr...

In this article, we draw upon the Conceptual Profile Theory to discuss the negotiation of meanings related to the energy concept in an 11th grade physics classroom. This theory is based on the heterogeneity of verbal thinking, that is, on the idea that any individual or society does not represent concepts in a single way. According to this perspect...

Article
The debate in the literature on the science‐practice interface suggests a diversity of opinions on how to link science and practice to improve conservation. Understanding this diversity is key to addressing unequal power relations, avoiding the consideration of only dominant views, and identifying strategies to link science and practice. In turn, l...
Article
In many experimental sciences, like particle physics or molecular biology, the proper place for establishing facts is the laboratory. In the sciences of population biology, however, the laboratory is often seen as a poor approximation of what occurs in nature. Results obtained in the field are usually more convincing. This raises special problems:...

In the book The Insect Societies, Wilson proposed categories of sociality that were presented as a landmark unification of terminology in the study of social behavior. Since then, many new behavioral patterns have been described, but they could not be fitted into any of the available categories, undermining the consensus around that well-establishe...

Applying scientific knowledge to confront societal challenges is a difficult task, an issue known as the science–practice gap. In Ecology and Conservation, scientific evidence has been seldom used directly to support decision-making, despite calls for an increasing role of ecological science in developing solutions for a sustainable future. To date...
