Private Universe Project in Mathematics: Workshop 2. Are You Convinced?
Proof making is one of the key ideas in mathematics. Looking at teachers and students grappling with the same probability problem, we see how two kinds of proof—proof by cases and proof by induction—naturally grow out of the need to justify and convince others.,Englewood, New Jersey—Teachers Workshop Englewood, a town with unsatisfactory student test scores, is implementing a long-term project to improve math achievement.

Sunlight and the Seasons
Children study seasonal change in sunlight in a global game of hide and seek. Students try to find 10 "mystery classes" hiding around the globe. The amount of sunlight is the central clue. Other clues link to each location's history, geography, culture, and more. Through these interrelated investigations, students discover that sunlight drives all living systems and they learn about the dynamic ecosystem that surrounds and connects them. This project reinforces a key concept: Changing sunlight d

Adaptations of Aquatic Insects to Habitat and Food Resources in Streams
This exercise is a field study of the ecology of aquatic insects in a small stream. By using the inquiry technique, students discover how different animals have unique adaptations for being successful in particular habitats, especially at small spatial scales. Students also learn how these specializations establish essential ecological roles for the aquatic insects in stream ecosystems. Thus, students gain an appreciation of how biodiversity is not just a list of species in a particular environm

5.1 Common sense revisited

It is worth taking a little time to reflect on what we have discovered so far. Starting from ‘what everybody knows’ about a social problem – or what are sometimes called the common-sense understandings – allows us to see a number of things if we apply the scepticism of being a stranger in our own society.

First, there is a question about whether particular issues are commonly understood to be social problems. As we have seen, there are views which say either that pov

When Everything Looks Like a Nail: Graph Models of the Internet
The general appeal of abstracting real-world networks to simple graphs is understandable and has been partly responsible for fueling the new field of "network science". However, as the Internet application has demonstrated, such abstractions that ignore much of what engineers consider as critical come at a price. For example, they can lead to the study of graph models that have little in common with the real-world networks that motivated these models in the first place. In turn, they tend to foc

Worldwide Amphibian Declines
AmphibiaWeb is an online system enabling anyone with a Web browser to search and retrieve information relating to amphibian biology and conservation. This site was inspired by the global declines of amphibians, the study of which has been hindered by the lack of multidisplinary studies and a lack of coordination in monitoring, in field studies, and in lab studies. We hope AmphibiaWeb will encourage a shared vision for the study of global amphibian declines and the conservation of remaining amphi
