Didactic Restrictions on the Teacher’s Practice: The Case of Limits of Functions in Spanish High Schools     

Joaquim BarbÉ  Marianna Bosch  Lorena Espinoza  Josep GascÓN 《Educational Studies in Mathematics》2005,59(1-3):235-268

The Anthropological Theory of Didactics describes mathematical activity in terms of mathematical organisations or praxeologies and considers the teacher as the director of the didactic process the students carry out, a process that is structured along six dimensions or didactic moments. This paper begins with an outline of this epistemological and didactic model, which appears as a useful tool for the analysis of mathematical and teaching practices. It is used to identify the main characteristics of the mathematical organisation around the limits of functions as it is proposed to be taught at high school level. The observation of an empirical didactic process will finally show how the internal dynamics of the didactic process is affected by certain mathematical and didactic constraints that significantly determine the teacher’s practice and ultimately the mathematical organisation actually taught.  相似文献   

Dialogue between theories interpreted as research praxeologies: the case of APOS and the ATD     

Marianna Bosch  Josep Gascón  María Trigueros 《Educational Studies in Mathematics》2017,95(1):39-52

The notion of “praxeology” from the anthropological theory of the didactic (ATD) can be used as a framework to approach what has recently been called the networking of theories in mathematics education. Theories are interpreted as research praxeologies, and different modalities of “dialogues” between research praxeologies are proposed, based on alternatively considering the main features and proposals of one theory from the perspective of the other. To illustrate this networking methodology, we initiate a dialogue between APOS (action-process-object-schema) and the ATD itself. It starts from the theoretical component of both research praxeologies followed by the technological and technical ones. Both dialogue modalities and the resulting insights are illustrated, and the elements of APOS and the ATD that the dialogue can promote and develop are underlined. The results found indicate that a complete dialogue taking into account all components of research praxeologies appears as an unavoidable step in the networking of research praxeologies.  相似文献

A hybrid approach to university subject learning activities     

Luz Adriana Osorio Gómez  Josep M. Duart 《British journal of educational technology : journal of the Council for Educational Technology》2012,43(2):259-271

In order to get a better understanding of subject design and delivery using a hybrid approach, we have studied a hybrid learning postgraduate programme offered by the University of the Andes, Bogotá, Colombia. The study analyses students' perceptions of subject design and delivery, with particular reference to learning activities and the roles of lecturers and students during moments of interaction. Elements of socio‐cultural activity theory were taken as a reference for subject analysis. It is a qualitative research project containing some quantitative data. For the purposes of the study, the following instruments were designed and applied: a student survey, student interviews (by subject), lecturer interviews, and a subject design and planning observation guide. The study's conclusions present the characteristics of learning activities and of student–lecturer and student–student interaction that fostered the attainment of subject learning objectives. These characteristics can make a positive contribution to the process of subject design and delivery using a hybrid approach, meaning integration between face‐to‐face and e‐learning actions in the delivery of learning activities.  相似文献   

Rational tool use and tool choice in human infants and great apes     

Buttelmann D  Carpenter M  Call J  Tomasello M 《Child development》2008,79(3):609-626

G. Gergely, H. Bekkering, and I. Király (2002) showed that 14-month-old infants imitate rationally, copying an adult's unusual action more often when it was freely chosen than when it was forced by some constraint. This suggests that infants understand others' intentions as rational choices of action plans. It is important to test whether apes also understand others' intentions in this way. In each of the current 3 studies, a comparison group of 14-month-olds used a tool more often when a demonstrator freely chose to use it than when she had to use it, but apes generally used the tool equally often in both conditions (orangutans were an exception). Only some apes thus show an understanding of others' intentions as rational choices of action plans.  相似文献   

Competency Maps: an Effective Model to Integrate Professional Competencies Across a STEM Curriculum     

Fermín Sánchez Carracedo  Antonia Soler  Carme Martín  David López  Alicia Ageno  Jose Cabré  Jordi Garcia  Joan Aranda  Karina Gibert 《Journal of Science Education and Technology》2018,27(5):448-468

Curricula designed in the context of the European Higher Education Area need to be based on both domain-specific and professional competencies. Whereas universities have had extensive experience in developing students’ domain-specific competencies, fostering professional competencies poses a new challenge we need to face. This paper presents a model to globally develop professional competencies in a STEM (science, technology, engineering, and mathematics) degree program, and assesses the results of its implementation after 4 years. The model is based on the use of competency maps, in which each competency is defined in terms of competency units. Each competency unit is described by a set of expected learning outcomes at three domain levels. This model allows careful analysis, revision, and iteration for an effective integration of professional competencies in domain-specific subjects. A global competency map is also designed, including all the professional competency learning outcomes to be achieved throughout the degree. This map becomes a useful tool for curriculum designers and coordinators. The results were obtained from four sources: (1) students’ grades (classes graduated from 2013 to 2016, the first 4 years of the new Bachelor’s Degree in Informatics Engineering at the Barcelona School of Informatics); (2) students’ surveys (answered by students when they finished the degree); (3) the government employment survey, where former students evaluate their satisfaction of the received training in the light of their work experience; and (4) the Everis Foundation University-Enterprise Ranking, answered by over 2000 employers evaluating their satisfaction regarding their employees’ university training, where the Barcelona School of Informatics scores first in the national ranking. The results show that competency maps are a good tool for developing professional competencies in a STEM degree.  相似文献
