ABSTRACT
B A rapid review was conducted to describe pesticide exposure assessment methodologies in Agricultural Work Contexts (AWC)s in Latin America and the Caribbean (LAC), in order to provide elements to reduce vulnerabilities within the agricultural population. A final number of 79 articles were selected from Medline via Pubmed, LILACS, and SciELO. In the region, family agriculture is the predominant form of agricultural production (72%) in informal agricultural work contexts (AWCs), which are characterized by small-scale diversified agricultural production, lower educational attainment, limited income, and a lack of social and healthcare security for the families. Indirect exposure assessment methods were the most commonly reported (58%), and its use was associated with informal AWCs (p = 0.011). Understanding AWCs and employing appropriate assessment methods can contribute to addressing vulnerabilities in the agricultural sector.

Este trabajo presenta los resultados de una investigación educativa en la materia de Patrimonio Documental impartida en la Escuela de Ciencias de la Información de la Universidad Autónoma de San Luis Potosí. Para la investigación, se siguieron tres momentos. En la primera etapa se investigaron los resultados del uso de las herramientas didácticas como los mapas conceptuales, los estudios de caso y los problemas, entre otros. En la segunda se aplicó un cuestionario sobre el aprendizaje de la asignatura para determinar los temas de interés o los que fueron complicados para estudiantes, y que requirieron de reforzamiento o mayor profundización. En la tercera se elaboró una rúbrica que establece un parámetro de los posibles resultados finales del aprendizaje del grupo. Lo más importante de la aplicación fue la identificación puntual de las barreras de aprendizaje y la realización de acciones para que el alumnado se apropiara del conocimiento. Las partes fuertes del curso se relacionaron con las áreas directamente correspondientes a las Ciencias de la Información Documental y la historia. La parte más débil es la tasación o asignación del valor económico de los bienes bibliográficos y documentales, en virtud de que esta se consolida con un amplio conocimiento del mercado y con la experiencia.
This paper presents the results of educational research in the field of documentary heritage taught at the School of Information Sciences at the Autonomous University of San Luis Potosi. For research, three elements are followed. The first element results of the use of teaching tools such as concept maps, case studies and problems, among others that were investigated. The second consists of a questionnaire on learning of the subject he is used to determine the topics of interest or those that were complicated for students and required reinforcement or further explanations. The third one consists on the development of a rubric establishing a parameter of possible final learning outcomes of the group. Regarding the application, the most important was timely identification of students' barriers for learning and performing actions to take ownership of knowledge. The strongest parts of the class directly related to the areas corresponding to Sciences of the Documentary Information and history. The weakest part is pricing or allocation of the economic value of library and documentary goods, due to the fact that this task is consolidated with extensive market knowledge and experience.
