R&D: The Development of Student Cohorts for the Enhancement of Mathematical Literacy in Under Served Populations

位于马萨诸塞州剑桥的代数项目正在开发和进行一项研究，该研究被称为队列模型，用于解决在州和地区考试中表现最差的四分之一学生的数学教育问题。 该模式具有以下特点：1）每个队列学校承诺四年减少20名学生的班级规模和教师的共同规划期; 2）队列学生承诺四年每天上90分钟的数学课，并参加暑期学习班; 3）学生在所有四年中都使用代数项目教材; 4）教师同意每年2-3周的专业发展和代数项目小组成员的课堂访问。 预测的结果是，大多数学生将在整个四年中留在这个队列中，几乎所有这样做的学生都将在大学入学考试中表现良好，被录取，并将通过数学补习课程的考试。

The Algebra Project in Cambridge, MA is developing and conducting research on what it describes as the Cohort Model for addressing the mathematics education of students that perform in the bottom quartile on state and district tests. The model has the following characteristics: 1) each cohort school commits to four years of reduced class size of 20 students and a common planning period for the teachers; 2) cohort students commit to take mathematics classes every day for 90 minutes for four years and to participate in summer institutes; 3) students use Algebra Project instructional materials for all four years; and 4) teachers agree to 2-3 weeks of professional development per year and classroom visits by Algebra Project team members. The predicted outcome is that most students will remain in the cohort for all four years and that almost all of those who do will perform well enough on college entrance exams to be admitted and will test out of remedial mathematics courses.
