Science education and the “state of the world”: a programme of activities to enhance teacher’s perception of global problems and possible remedies
2003
A literatura sobre formação de professores de ciências não tem tratado suficientemente a situação do mundo quanto a uma percepção global de seus graves problemas atuais. O presente artigo consiste essencialmente de um programa de atividades a ser desenvolvido com professores em formação e em exercício, que visa favorecer uma reflexão coletiva e conscientização sobre essa problemática. Nesta perspectiva é apontado um conjunto de referências e questões para um debate fundamentado sobre vários dos fatores associados à degradação da vida e sobre possíveis medidas para o enfrentamento da emergência planetária. Investigações preliminares sobre a utilização do programa proposto têm revelado result…
Perceptions of university students about their education in physics in secondary education
2018
Este artículo presenta los resultados de un cuestionario diagnóstico sobre las percepciones hacia la física, por parte de 104 estudiantes, quienes inician su carrera profesional de Licenciatura en Ciencias Naturales y Educación Ambiental, en una universidad colombiana. Este estudio, se centró en las siguientes categorías: experiencias sobre el aprendizaje de la física, metodología del profesor en la clase de física, dificultades de los estudiantes para aprender física y sugerencias para mejorar su enseñanza. Los resultados reflejan la importancia de explorar y generar estrategias, que permitan optimizar las cuatro dimensiones; por ejemplo, en relación al aprendizaje de la física, los partic…
Elementary Math to Close the Digital Skills Gap
2018
All-encompassing digitalization and the digital skills gap pressure the current school system to change. Accordingly, to ’digi-jump’, the Finnish National Curriculum 2014 (FNC-2014) adds programming to K-12 math. However, we claim that the anticipated addition remains too vague and subtle. Instead, we should take into account education recommendations set by computer science organizations, such as ACM, and define clear learning targets for programming. Correspondingly, the whole math syllabus should be critically viewed in the light of these changes and the feedback collected from SW professionals and educators. These findings reveal an imbalance between supply and demand, i.e., what is ove…
Making the case for policy : persuasiveness in higher education, science and technology policy discourse
2015
Policy texts present problems, propose solutions to those problems and persuade multiple audiences of the legitimacy of the proposed problems and solutions. The rhetorical analysis of two decades of higher education and science and technology discourse in Finland, Germany, UK, Portugal and USA highlights the discursive elements that contribute to persuasiveness of policy, construe it as rational and logical, and create a sense of urgency in bringing it about. I argue that the analytical and hortatory registers of policy discourse foreground competitive and hierarchical relations of countries and their higher education systems. By construing certain state of affairs and courses of action as …
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 …
Arithmetic, Logic, Syntax and MathCheck
2019
MathCheck is a web-based tool for checking all steps of solutions to mathematics, logic and theoretical computer science problems, instead of checking just the final answers. It can currently deal with seven problem types related to arithmetic, logic, and syntax. Although MathCheck does have some ability to perform symbolic computation, checking is mostly based on testing with many combinations of the values of the variables in question. This introduces a small risk of failure of detection of errors, but also significantly widens the scope of problems that can be dealt with and facilitates providing a concrete counter-example when the student’s solution is incorrect. So MathCheck is primari…
Relations between representational consistency, conceptual understanding of the force concept, and scientific reasoning
2012
Previous physics education research has raised the question of “hidden variables” behind students’ success in learning certain concepts. In the context of the force concept, it has been suggested that students’ reasoning ability is one such variable. Strong positive correlations between students’ preinstruction scores for reasoning ability (measured by Lawson’s Classroom Test of Scientific Reasoning) and their learning of forces [measured by the Force Concept Inventory (FCI)] have been reported in high school and university introductory courses. However, there is no published research concerning the relation between students’ ability to interpret multiple representations consistently (i.e.,…
Challenging Transmission Modes of Teaching in Science Classrooms : Enhancing Learner-Centredness through Dialogicity
2017
There is an ongoing reform towards more inquiry-based teaching in school curriculum policy in South Africa. Reform towards more inquiry-based approaches is already integrated in pre-service teacher education programmes. As inquiry-based approaches have been gaining momentum worldwide, there is an increasing concern that dialogic interaction in classroom communication is being neglected. This is especially within teacher-orchestrated classroom interactions that should foster greater learner centredness and thus authentic scientific inquiry. In learner-centred teaching approaches, student contributions should be explicitly taken into account as part of classroom interactions in science. Learn…
