Constructivist Model for Learning
The behaviorist theory popularized by B.F. Skinner still drives much of the practice of science education. For more than a quarter century, schools and teachers have been creating behavioral goals and objectives. Curricula have been tightly sequenced according to a belief that the best way to learn is to master small bits of knowledge and then integrate them into major concepts. Assessment practices have tended to focus on measurement of knowledge and skills, with little emphasis on performance and understanding. Since the late 1980s, however, researchers have been building an understanding of learning that grows out of cognitive and developmental psychology. All knowledge is constructed through a process of reflective abstraction. The constructivist classroom presents the learner with opportunities to build on prior knowledge and understanding to construct new knowledge and understanding from authentic experience.

The Creativity Crisis: Hardback: Roberta Ness
Strong critique of the academic system from a leading university dean and expert in science and innovationExplores the question of why science finds itself at a crossroad between extraordinary possibility and frustrating inactionA cogent and urgent argument for a rebalancing of priorities in funding agencies, universities, and industriesDescribes opportunities for reinvigorating scientific innovation, such as engaging broad-based resources, capturing the richness of available talent for the purpose of serving society's interests, and gaining flexibility through failing as quickly and painlessly as possibleEvery day we hear about some fascinating new discovery. Yet anemic progress toward addressing the greatest risks to humankind — clean energy, emerging infections, and cancer — warns us that science may not be meeting its potential. Indeed, there is evidence that advances are slowing. Creation and caution in science should be in balance, but they are not.
