Trabajo colaborativo, un tejido que hace trama entre la escuela y la institución formadora

Presentamos un trabajo colaborativo construido entre profesoras del IFD N° 12 y maestras de la Escuela N° 178, de la ciudad de Neuquén (Argentina). En el marco de un ciclo de desarrollo profesional docente convocado por el INFD, nos propusimos -como formadoras de maestros- “acampar en el otro escenario”, para conocer más profundamente el funcionamiento de la enseñanza de la matemática en la escuela primaria. Diseñamos un dispositivo de acompañamiento que nos permitió reconocer cómo van tomando decisiones en torno al tratamiento del cálculo en 2° grado, focalizando en algunos procesos de cambio en las condiciones reales de desempeño laboral.

Letter to the Editor: Calculation of photoionized plasmas with an average-atom model

We use a simple average-atom model (NIMP) to calculate the distribution of ionization in a photoionization-dominated plasma, for comparison with recent experimental measurements undertaken on the Z-machine at the Sandia National Laboratory. The agreement between theory and experiment is found to be as good for calculations with an average-atom model as for those generated by more detailed models.

Reflexive learning in pre-service training of primary school teachers: from experience to assimilation of contents

This article presents an educational experiment carried out in the Primary School Teaching Degree at the University of Barcelona. Specifically, the article analyses the application of the “Work Corners” approach in a core subject. In a three-year action research process, trainers put into practice an innovation which enabled them to boost cooperative work and reflexive learning among trainees. Firstly, the theoretical model underpinning the project and guiding many of the actions carried out by the training team is presented. After providing detailed information on the practical development of the experiment, the data-gathering process and its results are shown. Various information-gathering strategies were used in assessing the project, such as a questionnaire, participant observation, and teachers’ diaries. The results demonstrate, amongst other things, that “work corners” offer viable and appropriate educational conditions for the articulation of theoretical and practical knowledge, for building professional knowledge, and therefore, the beginnings of a reflexive teaching practice.

Co-evaluation as a strategy to improve working group dynamics: an experience in Sport Sciences

The aim of this study was to analyze if the perceptions of students before and after carrying out the work, that is, their perception of different aspects of the functioning of the group, the working skills acquired as well as those they think that need to be improved, varied depending on whether the contribution of the different members of the group was being co-evaluated or not. 144 students of Physical Activity and Sport Sciences participated in this study. In order to analyze the students' perception of group work the adapted questionnaire by Bourne et al. (2001) was used. Results showed that groups which implemented co-evaluation assessed more negatively the experience in general than those which did not. However, co-evaluation groups perceived their competence to work as a team had improved to a greater extent than the groups without co-evaluation, evaluating more positively both the performance and the result of work and increasing their knowledge of the other team members. Using a co-evaluation system seems to generate both a better assessment of the running of the team and the result of its work.
