如何提高小学生的科学成绩和综合素质

小学教育的对象是祖国的花朵,做好学生小学时候的教育工作,对学生长大后的发展有重要的意义,甚至影响学生的一生。本文对如何提高小学生的学习成绩和综合素质进行了简要的论述。     

放飞童心 “活”教语文

新的教育理念要求教师要把语文这门课程同社会生活联系起来,要求教师要有全新的视野,创造性地使用课文这个例子,用好这个例子,用足这个例子。用好例子即是说理透彻;用足例子是运用要充分;用活例子是要有创造性。     

Bridging knowing and learning: a suggestion for accounting education

This teaching note describes an exercise which appears to prompt students to reflect on their learning. The exercise is based on five pairs of words concerned with knowing and learning: (1) learn/study, (2) educate/train, (3) know/understand, (4) teach/tutor, and (5) student/pupil. The exercise may appear trivial, even frivolous, but when successful, it can compel students to reflect, often for the first time, on the meaning and purpose of their educational experience. Frequently, students make explicit previously unarticulated views and feelings about the process and content of their educational programmes.     

Are people emotionally aroused by hypothetical medical scenarios in experiments? An eye tracking study with pupil dilation

Background: Many studies on the communication of medical risks use hypothetical medical scenarios. The results of these scenarios should have sufficient predictive accuracy to be generalized to real life; thus, it is important to know whether hypothetical medical scenarios work and whether there is a relationship between risk level and emotional arousal. Methods: In an eye tracking experiment (N = 67), we investigated the influence of a simple hypothetical medical scenario on pupil dilation, a measure of emotional arousal. In this medical scenario, the participants were shown three risk levels (low, middle, and high) and had to estimate the probability that a hypothetical patient has colon cancer. They were also given a non-medical scenario that controlled for changes in illumination and cognitive workload. Therefore, we supposed that the difference in pupil diameter between the medical and the non-medical scenario was due to emotional arousal. Results: We found that our hypothetical medical scenario had a significant effect on pupil diameter. The mean values of the mean pupil diameter in the first fifth of the fixations were higher for all risk levels in the medical scenario than in the non-medical scenario. In a more detailed analysis of the difference in pupil diameters between the two scenarios, we detected that, for the high-risk level, the emotional difference values (between the medical and non-medical scenarios) differed significantly from zero. Furthermore, we found that higher risk levels lead to higher emotional arousal and higher probability estimates. Conclusions: Even simple hypothetical medical scenarios cause emotional arousal. Thus, hypothetical medical scenarios work, and the results of studies not using real patients can be generalized to real medical situations.     

从小学生心理特征来探讨快乐教育在体育中的应用

近年来应试教育的弊端不断暴露,各种批评都欲将它扫出历史舞台。在应试教育与素质教育交替的背景下,快乐教育的响声也响亮了起来,在理论和实践层面都有广泛响应。快乐教育着手激发学习兴趣和增加学习活力,是教育的一大进步。本文阐述了快乐教育的含义,从动机、兴趣、情绪情感和意志等方面分析了小学生的心理特征,根据其心理特征提出了在小学体育中实施快乐教育的措施和方法。     

Is the high school dropout rate an increasing function of the proportion of the population in the US cities that is Hispanic? Exploratory evidence

This empirical note seeks to provide preliminary insights into factors that may have influenced the high school dropout rate in the US cities. For some 300-plus cities for the year 2011, OLS estimates reveal that the dropout rate is a decreasing function of both the per cent of the population that is Hispanic and per pupil public education spending at the elementary and secondary levels. In addition, the estimates find that the dropout rate is an increasing function of the per cent of the population that consisted of families with children and that was classified as being at or below the poverty level and the per cent of the population aged 25 years and older that did not have a high school diploma.

面向近眼式应用的快速瞳孔中心定位算法

针对Hough圆变换、最小二乘法椭圆拟合瞳孔中心定位算法中运算量大的问题,提出一种基于椭圆外切矩形的快速瞳孔中心定位算法。该算法从人眼图像中通过阈值分割得到瞳孔区域,对瞳孔区域进行边缘像素点的提取,然后利用椭圆外切矩形模型定位出瞳孔中心。通过Matlab对中国科学院自动化研究所公开的虹膜数据库中756张人眼图像进行遍历实验验证,所提算法定位准确率为98.3%,平均用时0.192 s。在同等条件下,与Hough圆变换、最小二乘法椭圆拟合算法进行对比,在保证定位准确率的同时,所提算法平均用时更少。实验结果表明,所提算法能够快速准确地完成瞳孔的中心定位。
