Discussing Mathematical Learning and Mathematical Praxeologies from a Subject Scientific Perspective
2018
International audience; This programmatic contribution discusses the link between concepts from Anthropological Theory of Didactics (ATD) and the “subject-scientific point of view” according to Holzkamp (1985, 1993). The main common concern of ATD and the subject-scientific approach is to conceptualize and analyse “objects” like “institutionalized mathematical knowledge” and “university” not as conditions that cause reactions but essentially as meanings in the sense of generalized societal reified action possibilities. The link of both approaches is illustrated by the issue of “real numbers” in the transition from school to university: Hypotheses are derived for further actual-empirical res…
End Users’ Perspective of Performance Issues in Google Play Store Reviews
2022
The success of mobile applications is closely tied to their performance which shapes the user experience and satisfaction. Most users often delete mobile apps from their devices due to poor performance indicating a mobile app’s failure in the competitive market. This paper performs a quantitative and qualitative analysis and investigates performance-related issues in Google Play Store reviews. This study has been conducted on 368,704 reviews emphasizing more 1- and 2-star reviews distributed over 55 Android apps. Our research also reports a taxonomy of 8 distinct performance issues obtained using manual inspection. Our findings show that end-users recurrently raised Updation (69.11%), Respo…
Diversity begets diversity: A global perspective on gender equality in scientific society leadership.
2018
Research shows that gender inequality is still a major issue in academic science, yet academic societies may serve as underappreciated and effective avenues for promoting female leadership. That is, society membership is often self-selective, and board positions are elected (with a high turnover compared to institutions)—these characteristics, among others, may thus create an environment conducive to gender equality. We therefore investigate this potential using an information-theoretic approach to quantify gender equality (male:female ratios) in zoology society boards around the world. We compare alternative models to analyze how society characteristics might predict or correlate with the …
Sensitivity of bipartite network analyses to incomplete sampling and taxonomic uncertainty
2023
Bipartite network analysis is a powerful tool to study the processes structuring interactions in ecological communities. In applying the method, it is assumed that the sampled interactions provide an accurate representation of the actual community. However, acquiring a representative sample may be difficult as not all species are equally abundant or easily identifiable. Two potential sampling issues can compromise the conclusions of bipartite network analyses: failure to capture the full range of interactions (sampling completeness) and use of a taxonomic level higher than species to evaluate the network (taxonomic resolution). We asked how commonly used descriptors of bipartite antagonisti…
Addressing Complexity in Science|Environment|Health Pedagogy
2019
This paper aims to discuss complexity as a key feature for understanding the role of science knowledge in environmental and health contexts—a central issue in Science|Environment|Health pedagogy. Complex systems are, in principle, not predictable. In different contexts, ephemeral mechanisms produce different, sometimes completely unexpected results. The art of decision-making in complex contexts is to take scientific knowledge into account but to interpret its meaning in terms of concrete complex contexts. This is illustrated by four empirical studies on Science|Environment|Health issues, presented midway through this paper. The findings underscore the importance of introducing complexity i…
El cine de ciencia ficción para desarrollar cuestiones sociocientíficas y el pensamiento crítico
2021
espanolEste articulo de reflexion describe como el cine de ciencia ficcion [CCF] puede ser utilizado en la ensenanza de las ciencias desde la perspectiva de las cuestiones sociocientificas [CSC] para contribuir al desarrollo de competencias de pensamiento critico [PC], ya que el CCF se nutre de la ciencia, de la que obtiene conocimiento, pero tambien de problematicas que relacionan el mundo cientifico con la sociedad, la economia o la moral. Por ello, se reflexiona sobre el PC y su relacion con las ciencias. A continuacion, vemos que el cine legitima visiones del mundo. Sin embargo, debido a que el CCF trata temas como la manipulacion genetica, la inteligencia artificial o el calentamiento …
Ethical issues in the teaching and learning of health topics in schools: the conceptions of teacher trainees
2013
There has been little research on how teacher trainees can be educated to deal with ethical issues, or on trainees' conceptions of these issues. Using written essays, this study aimed to examine health education teacher trainees' (N = 35) conceptions of the ethical aspects involved in teaching and learning health topics. A qualitative content analysis revealed three broad themes: health education as an ethical subject, the teacher as an ethical professional, and spaces for learning. The results reflect the content areas focused on in health education teacher training, and provide new insights into topics that can be useful in developing teacher training. peerReviewed
Foucault: il potere oltre le regole. Repliche a Celano, Moreso, Segatti e Spena
2020
In questo articolo rispondo alle critiche e ai commenti alla mia ricostruzione della concezione del potere di Michel Foucault proposti da Bruno Celano, José Juan Moreso, Marco Segatti, Alessandro Spena. Mi concentro in particolare sui seguenti aspetti: la connessione fra la nozione foucaultiana di potere e il conflitto; la distinzione fra potere disciplinare, potere governamentale, e potere normativo; la concezione foucaultiana della libertà come autorialità; ciò che Foucault può suggerire riguardo ad alcune “macchie cieche” della teoria del diritto contemporanea.
El impacto del cambio climático en la movilidad humana : las migraciones climáticas en el contexto internacional y europeo
2021
For decades, the migration phenomenon has been one of the thorniest regulatory issues in the European Union (EU) policy. In addition, today, the fight against climate change in all regions of the world makes the situation worse for the new ?climate refugees? or ?environmental displaced people?, whose legal status is not yet covered by the ancient 1951 Refugee Convention.
The (im)possible success of disadvantaged students. Reflections on education, migration and social change
2019
The paper focuses on the ?unexpected pathways? of successful students with an immigrant background: these biographical routes, that seems socially impossible, raise theoretical issues around the individual-society, actor-structure relationship. Disadvantaged students who succeed represent a sociological challenge in the attempt to understand atypical situations and to identify the institutional processes and the structural opportunities that facilitate them, reducing ethnic inequalities in education. This framework is the starting point of the Su.Per. project (Success in educational pathways of students with immigrant background), based on the collection of written autobiographies of 65 imm…
