随着以“培养学科核心素养和关键能力”为教育目标,以“落实立德树人”为根本教育任务的指导思想的确立,高考命题也响应了党中央“立德树人、五育并举”的号召,增加了许多涉及文化背景或者学科互相融合的情境问题.解决这些问题除了要求学生有较高的学科专业素养外,还需要学生有较强的阅读理解能力.文章统计了近3年全国高考数学题的阅读量,结合普通高中数学人教A版教材中的数学阅读案例,站在一线教师的视角谈谈普通高中阶段数学阅读教学的实施建议. 相似文献

Public hospitals are the most important components of health systems and account for a large proportion of health resources in China. However, few researches on the efficiency assessment of public hospitals have been conducted in Tianjin, China. On the basis of the data of annual health service report in 2013 from the Ministry of Health, we measured the relative efficiency of the tertiary general public hospitals in Tianjin and estimated the magnitudes of output increase and/or input reduction by using data envelopment analysis to improve hospital efficiency. The main findings of this study indicate that more than half of the sample hospitals operate at a technical and scale efficiency, and the prevalent scale inefficiency is increasing returns to scale. Moreover, it is a prominent issue that health resource constraint and resource waste coexist. Health policy-makers and hospital administrators would need to address these problems by taking comprehensive measures such as optimizing the allocation of health resources, implementing hierarchical diagnosis and treatment, as well as innovating medical-service operating mechanism of public hospital to improve the people’s wellbeing. 相似文献
