1. A Hypothetical Learning Trajectory for the Understanding of Number Density in High School Students = Una Trayectoria Hipotética de Aprendizaje para la Comprensión de Densidad Numérica con Estudiantes de Bachillerato

Author

Suárez-Rodríguez, Mayra and Sacristán Rock, Ana Isabel

Abstract

During their school life, students learn mathematical topics that can be considered essential for the understanding of the property of density in the set of real numbers. Therefore, we detected a need to design and elaborate a Hypothetical Learning Path to include topics to help promote the learning of this property. This report shows results of a first stage of an educational experiment as part of an ongoing research. It describes how through the trajectory, high school students are able to recognize ways of finding numbers in an interval using various semiotic representations. We also describe some difficulties that students had to recognize the non-existence of a successor in real numbers. [For the complete proceedings, see ED630060.]

2. El porque de la importancia de la ninez: Dedicando esfuerzos a la atencion y desarrollo de la primera infancia (Why Children Matter: Investing in Early Childhood Care and Development).

Author

Bernard Van Leer Foundation, The Hague (Netherlands)., Cohen, Ruth, and Chetley, Andrew

Abstract

This Spanish-language publication reflects the philosophy and support of the Bernard van Leer Foundation for early childhood care and development. It highlights different approaches to early childhood care and development and explains why the foundation believes that investing in early childhood is one of the best ways of building a brighter, better future. The publication seeks to assist policy makers and program planners in their search for realistic, effective, and affordable ways to enhance early childhood care and development. The various approaches to early childhood interventions included in this document are run by a variety of partner organizations in the countries concerned: local and national governments, nongovernmental organizations, universities, and community agencies. They are given as examples of programs that build on local culture and local realities. Eight chapters cover the following topics: (1) why children matter; (2) the importance of the early years; (3) why parents are important; (4) involving parents; (5) involving the community; (6) benefits of early childhood interventions; (7) quality and cost; and (8) developing an agenda for action. Fourteen examples, included as sidebars in the chapters, profile efforts of several countries or address special topics. Contains 37 references. (HTH)

3. Seriacion: Un Procedimiento De Aprendizaje (Seriation: A Learning Procedure.)

Author

Mejia, Mercedes

Abstract

The development and application of a learning procedure for the seriation structure of children in the oscilatory state are described. The procedure was based on the structural genetic theory of learning. A study consisting of design and verification stages was carried out in Cali, Colombia. In the design stage six seriation treatments involving different materials (such as sticks, dolls and playdough) were developed and tested individually with seven children. Of the six designs, three were selected for use in the verification stage. In the verification stage, the learning procedure was applied individually to nine children attending the Nuestra Senora del Rosario school to verify its effect upon the development of the seriation structure. The complete procedure consisted of a pretest, three learning sessions and two posttests. A qualitative analysis of the children's behavior was emphasized in both stages of the study. In the verification stage the children's improvement in seriation ability was evaluated between pretest and posttest. The results showed a significant advance in most of the nine children. A summary in English is appended. (Author/RH)

4. Formacion de Formadores: Experiencias Institucionales en Planeamiento y Administracion de la Educacion. (The Formation of Educational Planners: Institutional Experiences in Planning and Administration for Education.

Author

United Nations Educational, Scientific, and Cultural Organization, Santiago (Chile). Regional Office for Education in Latin America and the Caribbean. and Senen Gonzalez, Silvia N. de

Abstract

Information collected from interviews with 15 ministers of education and 30 program directors and researchers at 18 universities in Venezuela, Costa Rica, Chile, Mexico, Colombia, Brazil, and Argentina is used to study academic programs which prepare persons to be educational planners and administrators. Section one describes background information, institutional and program characteristics, staffing, program evaluations, and future expectations of the institutional programs. Section two reports on conclusions of the study in terms of the necessity for educational programs, objectives, programs' contents, students, themes, changes, resources, graduates, and the relationship of a university to a national planning office. Section three includes recommendations and proposals. Conclusions suggest serious deficiencies in educational planning and administration programs because of reduction in funding and lack of adequate financial sources. The United Nations Educational, Scientific, and Cultural Organization (UNESCO) encourages interchange and cooperation among these countries to: (1) increase the quality of education for planners and administrators; and (2) develop new models of planning and administration management that are more flexible and democratic. Appendices present educational program information by country, by persons interviewed, and includes the questionnaire. (JHP)
