The notion of a dedicated time for black history instruction dates from 1926, when educator Carter Godwin Woodson created Negro History Week in a bid to promote a better understanding of the contributions of blacks. In 1976, Congress changed the week into a full month. Educators are now debating whether such lessons should be confined to one month or, instead, incorporated into class work all year long. Writer E. Jeanne Harnois reports on arguments that weaving black history, along with other minority contributions, into lessons throughout the year is better for all students.
