From PBS-American Field Guide, this website offers seventh- through ninth-grade teachers a downloadable unit comprised of four activities exploring the ocean's intertidal zone. The unit encourages students to consider the lives of marine organisms in this dynamic oceanic zone. The brief activities include links to video segments about several different tide pools, and a beach habitat as well. The longest activity requires 45 minutes, while the rest can be done in 30 minutes or less. The concise

Since the concept of permaculture was introduced by biogeographer Bill Mollison in the 1970s, it has attracted increasing interest from agriculturalists, designers, ecologists, and others. The Permaculture Research Institute (PRI) describes permaculture as "the harmonious integration of landscape and people providing their food, energy, shelter, and other material and non-material needs in a sustainable way. It is also the conscious design and maintenance of agriculturally productive ecosystems

Dans cet article, nous sommes intéressés à la détermination automatique de théorèmes-en-acte en algèbre. Ces théorèmes-en-acte ont été construits de façon abstraite, puis nous avons cherché à automatiser le mécanisme de leur diagnostic. Pour cela, nous avons utilisé le logiciel Aplusix comme support des productions des élèves qui permet d'enregistrer toutes les actions des élèves. Une base de règles correctes et erronées a été mise en place et un interpréteur de règles

The impact of simulator-based instruction on the diagramming of the interaction of light and matter
We examine the conceptual development resulting from an instructional experiment with an interactive learning environment in geometrical optics for introductory high school physics. How did teaching-learning processes come to change the ways in which students depicted various everyday optical situations in paper and pencil graphical representations? We view conceptual development as a process resulting in part from increasingly aligning one's practices to a target community by means of participa
