This institution, a small 4-year, historically Black institution, is enhancing its biology laboratories. Although the State of Missouri approved an expanded mission and additional degree programs in 1993, years of underfunding have left this college lacking the equipment necessary for effective undergraduate teaching. This is particularly true of the laboratory experience. The addition of an approved biology specialization area in the new secondary education program has meant that, while enrollment in upper-level biology laboratory courses has increased, the college has been unable to provide students with the hands-on laboratory experiences essential to preservice teachers. The conceptual foundation and thorough understanding gained through advanced laboratory experiments greatly enhances the entering teachers' ability to teach secondary-school science. The use of current technology in molecular biology and biotechnology, including differential centrifugation, ultraviolet spectrophotometric DNA analysis, and gel electrophoresis is a necessary practice, not a luxury. The preservice teacher has a particularly important role in the education of underrepresented groups. With a student enrollment that is 75 percent African American, this college has a long record of service to the nontraditional, first-generation college student from an economically disadvantaged background. Most participants are minority women themselves and, upon graduation, are likely to teach in predominantly minority, urban schools, mainly in the City of St. Louis. The long-range impact may be that a new generation of well-prepared teachers are making their own students ready for the challenges of the 21st century.

这个机构是一个小型的4年制历史上的黑人机构，正在加强其生物实验室。虽然密苏里州在1993年批准了一项扩大的使命和额外的学位课程，但多年的资金不足使这所学院缺乏有效的本科教学所需的设备。实验室的经验尤其如此。在新的中学教育计划中增加了一个批准的生物专业化领域，这意味着，虽然高级生物实验室课程的入学人数有所增加，但学院无法为学生提供实习教师所必需的动手实验室经验。通过先进的实验室实验获得的概念基础和透彻的理解大大提高了新教师教授中学科学的能力。在分子生物学和生物技术中使用当前的技术，包括差速离心、紫外分光光度DNA分析和凝胶电泳是必要的实践，而不是奢侈的。 副教师在教育代表性不足的群体方面发挥着特别重要的作用。随着学生入学率是75%的非洲裔美国人，这所大学有一个长期的服务记录，以非传统的，第一代大学生从经济上处于不利地位的背景。大多数参与者本身就是少数民族妇女，毕业后可能在主要是圣路易斯市的少数民族为主的城市学校任教。长远的影响可能是，新一代准备充分的教师正在使他们自己的学生为21世纪的挑战做好准备。
