为提高初中学业水平和综合素质教育,近几年有些地方中考进行改革,要求学生进行学科选择。新中考课程分为选修和必修两大类。必修课程为语文、数学、英语,选修课程为其他六门课程,从中选出三项。把最后总成绩作为中考录取的标准。跟传统排课不同,这里排课要求每人一张课表,问题变得复杂困难。本文以北京某初三课程为例,研究了新中考的排课问题。一般情况下约束和变量是上百万级的,无法求解。本文利用整数规划建模,然后把该问题转化成多阶段问题,每个阶段给出小问题的解,这样使得问题的求解变得可行。最终的排课结果,仅比预期增加三位老师就可以实现新中考的排课问题。本文的求解过程给新中考排课带来了新的启发。 相似文献

Internationally, the consequences of the ‘Mathematics problem’ are a source of concern for the education sector and governments alike. Growing consensus exists that the inability of students to successfully make the transition to tertiary level mathematics education lies in the substantial mismatch between the nature of entrants’ pre-tertiary mathematical experiences and subsequent tertiary level mathematics-intensive courses. This paper reports on an Irish study that focuses on the pre-tertiary mathematics experience of entering students and examined its influence on students’ ability to make a successful transition to tertiary level mathematics. Brousseau's ‘didactical contract’ is used as an intellectual tool to uncover and describe the contract that exists in two case mathematics classrooms in Irish upper secondary schools (Senior Cycle). Although the authors are professional mathematics educators and well informed about classroom practice in Ireland, they were genuinely surprised by the very restrictive nature of this contract and the damaging consequences for students’ future mathematical education. 相似文献

This paper presents a resource allocation model via Goal Programming (GP) in a long-range planning horizon in university management. In the proposed model, the introduction of new courses in the academic units and the allocation of available budget within the academic units as well as the forecast of the budget which is actually needed for better academic performance are taken into consideration. An illustrative example is presented to expound the model 相似文献

The decline in enrolments and interest in advanced mathematics studies is of growing concern internationally. Previous research suggests that a range of factors can influence students' academic decisions. The focus of the paper is on one of these potential sources of influence— students' perceptions of the tertiary mathematics learning environment. Data from two large-scale surveys (N = 1883) and from a smaller number of interviews (N = 71) with students enrolled in tertiary mathematics courses at five Australian universities are presented and discussed. Collectively, the survey results and the interview data reveal considerable variations in the quality of the teaching and student support available in different mathematics departments. Students' comments were constructive and offered valuable ideas for improving the existing situation, retaining current students and attracting others to mathematics. 相似文献

The new math was a several-decade-long movement to update school mathematics that began in the mid twentieth century in many countries around the world. It took many forms, but much of it involved the preparation of new instructional materials, including textbooks. Much of the new math activity in Europe and North America was stimulated by conferences and seminars of the Organisation for Economic Cooperation and Development (OECD) in the early 1960s. Although the initial reform efforts addressed secondary school mathematics courses that prepared pupils for tertiary education, those efforts quickly spread to primary school mathematics, to pupils not headed to tertiary education, and to non-OECD countries. Mathematicians and schoolteachers were divided about the direction that the new math reforms took. Although the new math is often deemed a failed endeavor, it changed not only school mathematics but also the way people and countries viewed school mathematics. 相似文献

基尼系数是现行较为通用的衡量一国收入分配差距的指标,利用灰色系统中的GM(1,1)预测模型,建立起对我国收入分配差距的预测模型,得到2005年基尼系数的预测值0.471,进而建立精度更高的新陈代谢模型,得到2006—2010年的基尼系数预测值,结果表明到2010年,基尼系数有可能临近0.5,基尼系数依然是攀升的,从而分配差距的扩大趋势依未改变,但增长幅度缓慢而平稳,这为当前及今后几年经济发展和调节收入分配差距的政策制定提供了一定的参考. 相似文献
