This guide explains how employers can support math and science achievement in U.S. schools. Section 1 reports data from Third International Mathematics and Science Study regarding the math and science achievement of students in grades 4, 8, and 12 worldwide. Section 2 establishes a link between academic achievement and workplace success through workplace examples of the application of basic academic knowledge and higher-order thinking skills. Discussed in section 3 are six ways for businesses to support increased math and science achievement: articulate workplace academic skill requirements and ensure their incorporation into academic standards; support more rigorous teaching training incorporating mastery of content and its application to success in the workplace; support programs that expose students to the world of work; support the use of clear, reliable, and broadly disseminated student and system performance data; use student achievement in hiring decisions; and encourage employees to increase their involvement with local schools. Section 4 poses 6 questions that business leaders can use to engage parents, employers, educators, colleges, and community members in efforts to improve math and science achievement, and section 5 contains an annotated bibliography of 17 resource organizations that can help employers support student achievement. Thirty-eight endnotes are listed. (MN)
