Time allocated to mathematics in post-primary schools in Ireland: are we in double trouble?

Mathematics educators and legislators worldwide have begun placing a greater emphasis on teaching mathematics for understanding and through the use of real-life applications. Revised curricula have led to the time allocated to mathematics in effected countries being scrutinised. This has resulted in policy-makers and educationalists worldwide calling for the inclusion of double class periods on the mathematics timetable. Research from the United States suggests that the introduction of double or block periods allow for the objectives of revised curricula to be realized. The aim of this study, which is set in the school context, is first to ascertain if schools in Ireland are scheduling double periods for mathematics at both lower post-primary level (Junior Cycle) and upper post-primary level (Senior Cycle). It also seeks to determine if there is a link between teachers’ levels of satisfaction with the time allocated to mathematics and the provision of double periods and to get insights from teachers in relation to their opinions on what can be achieved through the introduction of such classes. Questionnaires were sent to 400 post-primary schools (approximately 1600 teachers) which were selected using stratified sampling techniques. It was found that 8.7% of mathematics teachers reported the provision of double periods at Junior Cycle while 55% reported that double periods were included on their timetable at Senior Cycle. The study also identified a link between teachers’ levels of satisfaction with the time allocated to mathematics and the provision of double periods. Finally, teachers felt that double periods allowed for new teaching methodologies, which were promoted by the revised curricula, to be implemented and teaching for understanding was also more feasible. In essence, it was found that double periods have an influence on the mathematical experience of post-primary students as well as the teaching approaches employed.     

灰色关联度法在工业企业去库存中的应用

工业企业为了赢得市场竞争地位,必须向市场提供质量好、人民满意的产品,这就需要处理企业库存中市场过剩的、不对路的产品,也就是开展“去库存”工作。论文通过设置与库存相关的指标,计算临界值来判断工业企业产品是否“过剩”,再通过灰色关联度法进行优化排序,确定整个工业行业“去库存”的主要抓手。研究结果表明,工业企业去库存的主要抓手有三个:一要加速库存商品资金周转;二要提高产品销售率;三要降低库存商品占流动资产的比例。论文将研究结论用于徐工集团工程机械股份有限公司,得到有效的验证。     

普通物理综合设计实验课教学方法改革初探

开设普通物理综合设计实验课程目的在于培养学生动手能力、分析问题解决问题能力和创新能力。本文以首都师范大学物理系开设的普通物理综合设计实验为例讨论了具体的教学方法和过程,首先通过设计大量的预习思考题提高学生预习的针对性和预习效果,通过分组讨论来理解实验原理,并给出设计思路,最后通过实际实验锻炼学生的动手能力。该方法取得了良好的教学效果。
