保护好孩子的梦想

美国马萨诸塞州小男孩詹姆斯做梦都想拥有一套乐高"绿宝石午夜火车"玩具。他用了整整两年时间攒够了钱款,却失望地发现这款玩具已经停卖了,而无论是网上的少量存货还是二手转卖,它们的标价对詹姆斯来说都是天文数字。于是小男孩给乐高玩具写了一封信询问,却得知这款玩具已经停产。让人内心温暖的是,在詹姆斯11岁生日时,他收到了乐高悄悄寄来了这份惊喜。你一定想分享詹姆斯的快乐,小男孩脸上欢呼雀跃的表情,是不是也让你感动呢?这让我不禁联想起同样让人内心温暖的一个小女孩。当得知妈妈吃光了她的万圣节糖果时,小女孩红着眼眶,挤出笑容安慰妈妈说:妈妈我不生你的气,我只是有点伤心……吃那么多糖果会让你头痛,你应该多喝水……下一个万圣节我就不会伤心了,但你不能没有跟我商量就吃掉我的糖果,明年我们一起分享好吗?其实这只是父母们的一个万圣节恶作剧,还有很多小朋友也得到了同样的"噩耗",孩子们天真的各种抓狂让人捧腹,还有小女孩的"next Halloween we can share my candy"让人感动。我相信小女孩长大后,她如果听说有个小朋友特别渴望得到心中的"乐高",她也一定会帮助实现。瞧,正能量就是这样传播和积聚的。     

An afterschool intervention program for educationally disadvantaged young children

The research investigated the premise that if educationally disadvantaged children experience increased instructional time combined with an educational setting that is sensitive to their culture and that provides perceptions of control, enhanced achievement and interest in learning will result. The research setting was the Hilltop Emergent Literacy Project (HELP), an afterschool educational program serving poor, mostly African American five- to nine-year-olds (kindergarten to third grade) who reside in a subsidized apartment complex. A treatment group of 12 kindergartners was compared to a control group of 12 kindergartners. In the spring of kindergarten, the treatment group was outperforming the control group on standardized test scores, but both groups were below national norms. In the spring of first grade, the treatment group was still outperforming the control group and was above national norms in some areas. Report card data and qualitative indicators also provide evidence of the effectiveness of the program.We thank the Hilltop Emergent Literacy Project (HELP) head teachers Teresa Bunge and Diana Reamsnyder, the HELP students, and the many graduate and undergraduate students who have served at HELP. This program was partially funded through grants from the University of Toledo, Ohio Board of Regents, General Mills Foundation, and Toledo Public Schools.     

Mentoring preservice teachers: identifying tensions and possible resolutions

Tensions can occur in the mentor–mentee relationship during school-based professional experiences that require problem solving. What are the tensions for mentor teachers in preservice teacher education and how might these tensions be resolved? This qualitative study collected data from 31 high school mentor teachers about tensions experienced with preservice teachers during professional experience programmes. Three themes emerged around the causes of tensions (low- to high-level conflicts) within the mentor–mentee relationship, namely: (1) personal issues (i.e. incompatibility, personality differences, language); (2) pedagogical issues (i.e. lack of pedagogical and content knowledge, differences in teaching styles); and (3) professional issues. Strategies to resolve these tensions include: maintaining a positive professional relationship, regular feedback as a way to address issues, sharing responsibility and empowerment, and using empathy for specific situations. As a theoretical contribution, this study provides a model around low- and high-level conflict associated with personal, pedagogical and professional (3Ps) issues. The study focused on mentors only and further research is required about the tensions preservice teachers experience with their mentors and ways in which these tensions can be resolved.     

Correlation between performance in physics and prior mathematics knowledge

The final grade of 1403 students enrolled in the first semester of the introductory, pre-professional physics course has been correlated with performance on a precourse diagnostic test of mathematical skills. The students were from a total of eight different sections taught by six separate instructors over a three year time span. The student population has been separated into two groups, those who completed the course (913 students) and those who dropped (490 students). The drops were assigned a “projected final grade”based on performance up to date of withdrawal. The Pearson product-moment correlation for students who completed the course is 0.418 and correlation for the drops is 0.232. Both correlations are significant at the p < 0.001 level. This study suggests that prior mathematical ability is a primary influence on performance in the course, and has a secondary influence on the tendency to drop out of the course.     

Educational Reform in Russia and the USA: where are the troops?

To determine the level of support that differing concepts of educational reform had among the actual practitioners of public education in the former Soviet Union and the USA, a sample of teachers was surveyed to measure the value they placed on divergent educational goal statements as well as their respective philosophical orientations. This study found that US teachers were most committed to educational goals related to basic skills development and critical thinking and least supportive of goals related to creativity and enculturation; Russian teachers on the other hand were most supportive of interpersonal understanding and human relations, moral and ethical well‐being, and critical thinking, and least supportive of the goal related to citizenship and civic responsibility. With regard to educational philosophical orientation, US teachers were divided between maintaining order and stability, developing individual interests and abilities, and improving society. Russian teachers were more united in their belief that the purpose of education is to develop individual interests and abilities, with a significant minority selecting the ‘transforming society’ orientation.     

Understanding the dynamics of MOOC discussion forums with simulation investigation for empirical network analysis (SIENA)

This study attempts to make inferences about the mechanisms that drive network change over time. It adopts simulation investigation for empirical network analysis to examine the patterns and evolution of relationships formed in the context of a massive open online course (MOOC) discussion forum. Four network effects—homophily, reciprocity, transitivity, and preferential attachment—were tested to explain the dynamic mechanisms of interaction in the MOOC forum. Understanding the network dynamics of relationships will allow us to explore how to develop a robust peer-supported learning environment and in turn improve the online learning experience in MOOCs.
