The links listed above describe the declining number of African Americans that are entering the math and science fields.  The above abstracts list the causes and possble solutions to this growing problem.  The artcile and abstract listed mention specially three reasons why African Americans are not pursuing careers in the math, science and technolog field. Some of the reasons offered are discouragement, self doubt, and stereotypes. 
As educators, we must motivate our all students, we should encourage them to pursues careers that they are interested in regardless of socioeconmic status.  We should expose our students to math and science opportunities outside of the classroom.  Fieldtrips and webquests provide students the opportunit to explore and discover the wonderful world of science. 
These to articles could be shared with parents and teachers, this would expose them to some causes that prevents students from studying math.  If parents and teachers begin to understand that students just need a little motivation and encouragement hopefull the ccle of discouragement can end.
