Discussion Rhythm to Promote Student Participation

Teachers are partnering with students to establish a new rhythm in classroom questioning. This rhythm provides teachers and students with a silence for thinking at two crucial junctions in the questioning process: • Wait Time 1: After a question is posed but before a student is called on to answer. • Wait Time 2: Directly following that student’s response. Almost 50 years ago, Mary Budd Rowe (1969) famously discovered multiple benefits associated with intentionally pausing at these tw...

 Fox News and the Dangers of Confirmation Bias

So why not just say, “I may have mischaracterized things a few times” and move on? To understand why that’s impossible, you have to understand O’Reilly’s persona and the function he serves for his viewers. The central theme of The O’Reilly Factor is that the true America, represented by the elderly whites who make up his audience (the median age of his viewers is 72) is in an unending war with the forces of liberalism, secularism, and any number of other isms. Bill O’Reilly is a...

 Cost Benefits of Lead Cleanup

It's difficult to put firm numbers to the costs and benefits of lead abatement. But for a rough idea, let's start with the two biggest costs. Nevin estimates that there are perhaps 16 million pre-1960 houses with lead-painted windows, and replacing them all would cost something like $10 billion per year over 20 years. Soil cleanup in the hardest-hit urban neighborhoods is tougher to get a handle on, with estimates ranging from $2 to $36 per square foot. A rough extrapolation from Mielke's est...

 Potentially 90 Percent of Crime Rate Changes Explained by...

IN 1994, RICK NEVIN WAS A CONSULTANT working for the US Department of Housing and Urban Development on the costs and benefits of removing lead paint from old houses. This has been a topic of intense study because of the growing body of research linking lead exposure in small children with a whole raft of complications later in life, including lower IQ, hyperactivity, behavioral problems, and learning disabilities. But as Nevin was working on that assignment, his client suggested they might b...

 Interest in Genetics of "Lesser" Animals Betrays our Conn...

Genetics has enticed a great many explorers during the past two decades. They have labored with fruit-flies and guinea-pigs, with sweet peas and corn, with thousands of animals and plants in fact, and they have made heredity no longer a mystery but an exact science to be ranked close behind physics and chemistry in definiteness of conception. One is inclined to believe, however, that the unique magnetic attraction of genetics lies in the vision of potential good which it holds for mankind rat...

 Atheist and Religious Origins of Secular Humanism

Atheism and freethought trace their roots to ancient Greek philosophy, with its emphasis on rational inquiry and curiosity about the workings of nature. Other sources included early Chinese Confucianism, ancient Indian materialists, and Roman Stoics, Epicureans, and Skeptics. Submerged during the Dark Ages, freethought re-emerged in the Renaissance. With the Enlightenment, rationalist and empiricist thinkers laid foundations for the modern scientific outlook. Utilitarians emancipated morality...
