ATE AND STEM; A proposal to relate biology, geometry and technology.

El trabajo de grado de la especialización en Educación en Tecnología está enfocado en la elaboración de una actividad tecnológica escolar (ATE) que permita abordar las ciencias naturales, la geometría y la tecnología, en una propuesta de educación, desde el enfoque Science, Technology, Engineering and Mathematics (STEM). En el desarrollo del trabajo se encuentra la apropiación teórica que lo sustenta: desde lo pedagógico basado en el modelo constructivista y su enfoque construccionista; en lo didáctico basado en la propuesta STEM; así como en la elaboración de una ATE en donde se proponen actividades para trabajar conceptos de biomas con los animales representativos en Colombia; desde lo geométrico la clasificación, elaboración de polígonos que permiten construir la base de algunas figuras que se convertirán mediante la técnica del Paper Bomb, en un juguete agradable y divertido. En la construcción de la ATE también está inmerso el diseño y la elaboración de material a partir de elementos reutilizables, para armar los Paper Bomb, finalmente, las conclusiones, reflexiones y proyecciones tanto de las bases de este trabajo como de la actividad tecnológica escolar.This document presents the development of a School Technological Activity (STA) which focuses on the approach Science, Technology, Engineering and Mathematics (STEM) during the development of this thesis it is possible to identify the theoretical appropriation that sustains it: from the pedagogical perspective, the Constructivist Model and its Constructionist approach. In consequence, the didactics based on the STEM proposal within the elaboration of a School Technological Activity where activities intend to work on concepts of biomes with the representative animals in Colombia. Furthermore, it includes the classification and elaboration of polygons that allow building the base of some figures that will be transform into a nice and fun toy using the Paper Bomb technique. Consequently, the construction of the School Technological Activity covers the design and development of a material from reusable elements, the Paper Bomb, finally, conclusions of both bases of this work and School Technological Activity are described

The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project

The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity
