This work presents a literature review of research journals in science teaching in Latin America and the Caribbean with the aim of identifying, describing and characterizing the main lines of research. The documentary basis is made up of 15 scientific journals and 490 papers that report work in educational research. From the abstracts of the papers it was possible to identify the problems addressed, which were grouped into five dimensions: learning science, teaching science, the science curriculum, science teachers and students of science teaching. The results show that teaching and learning science is the main problem addressed by most studies conducted in Latin America and the Caribbean. [ABSTRACT FROM AUTHOR]

The Hondo transboundary river basin is a territory shared by Mexico, Guatemala and Belize. There is not enough information about mechanisms of cooperation in water issues in the river basil and the reasons that prevent this process. Nevertheless, we know about the existence of factors of conflicts that limit the cooperation. This article describes the factor of conflicts and their bonds with the cooperation around die water. The construction of the analysis was based in the grounded theory, with the use of the semi-structured interviews and the participant observation as tools of data collection. The data obtained was analyzed by a codification of information based on: the anthropic conflicts, their relation with the cooperation and the institutional paper as part of die factors of conflict. For the location of key stakeholders and the elaboration of interviews, it was necessary to take advantage of a hemerographic analysis and the existing relations as a result of a previous work in 2003, besides applying the technique of "snow ball" to identify new key stakeholders. The paper tries to highlight how existing potential anthropic conflicts in the river basin may affect processes and attempts for cooperation in water issues. [ABSTRACT FROM AUTHOR]

Using the argument that the educational systems in Latin American were inefficient, international politic and financial organizations promoted reforms to modernize the educational system in the region, using a free market logic. Chile was used as a laboratory for those reforms, which afterwards were applied to other Latin American countries. This paper analyses the argument that educational quality would be improved through competitiveness as a strategy to privatize the educational system by transferring its financing form public to private sources to the detrimental of the national system of education. Finally, this paper examines the modernization process and failure of the Mexican system of education organized from a free market model. [ABSTRACT FROM AUTHOR]
