The philosophy behind HighScope is based on child development theory and research. he HighScope Curriculum emphasizes active participatory learning. [ Active learning means students have direct, hands-on experiences with people, objects, events, and ideas. Children's interests and choices are at the heart of the HighScope programs. They construct their own knowledge through interactions with the world and the people around them. In active learning settings, adults expand children's thinking with diverse materials and nurturing interactions.http://en.wikipedia.org/wiki/HighScope

4. If the animal is a staple in the diet of humans, it may have a direct impact on the diet of humans such as if the tuna went extinct. If the animal is not a staple, it may still have an impact due to the fact that it may be a key food source for another animal which is a staple of the human diet. If plankton went extinct, everything that ate them, such as most fish, would then go extinct. Just as if honeybees became instinct, the pollination of our crops and produce would cease.

Beyond just eating animals, the extinction of creatures can affect our lives in other ways. A poll by the American Museum of Natural History finds that seven in 10 biologists believe that mass extinction poses a colossal threat to human existence, a more serious environmental problem than even its contributor, global warming; and that the dangers of mass extinction are woefully underestimated by almost everyone outside science

I think High/Scope is a reform that should be continued. The critics of the program say that the academic/social/economic results are not valid due to the small number in the test group. I believe that the High/Scope findings continue to be relevant in light of the need for early intervention strategies. The High/Scope curriculum provides opportunities for language development, positive social and learning skills, and addresses the home/school component by encouraging parents to become involved in the educational process.
Another disadvantage for some would be the cost of implementing the program. Teachers have to be trained (retrained) to enable them to execute an active learning curriculum. There needs to be a low staff to student ratio in the High/Scope curriculum, which is expensive. I believe the old adage applies here “An ounce of prevention is worth a pound of cure.” If we put the money into early intervention now, we avoid the cost of public assistance, jail, etc., later.
