Should I stay or should I go? Predictors and effects of studying abroad during high school

In an increasingly globalized and culturally diverse world, extended stays abroad during high school are considered important opportunities for acquiring and improving a variety of skills, most importantly, language achievement. This study examines both predictors and effects of studying abroad in an English-speaking country during high school, using population data from the second largest city in Germany (N = 5361; 13% went abroad). In order to determine the most central predictors of studying abroad, we employed logistic regression models in which students’ socioeconomic background emerged as the strongest predictor of studying abroad. To test the effects of studying abroad, we applied propensity score matching. Studying abroad had positive effects on standardized achievement, grades, and course choice in English, whereas it had hardly any effects on outcomes in math. Implications for studying abroad during high school and future research directions are discussed.

Does the Model of Language in the National Literacy Strategy Create Failure for Pupils from Differing Language Backgrounds?

The National Literacy Strategy (NLS) was introduced by the government in the wake of the hotly debated issue of falling educational standards in the UK. All schools were required to adopt the NLS Literacy Hour unless they could show their preferred programme would result in raised levels of achievement. My experience of delivering the Literacy Hour has been a process of adaptation to the needs of my pupils, who are drawn mainly from groups whose language backgrounds differ from that which is dominant in school. I have found that the requirements of NLS, together with many of the commercial resources used to teach it, are not appropriate for pupils from these groups and a question arose: is it the pupils who are in some way deficient or is it the approach and the resources being used? This article takes a case study of the use of a commercially produced resource to explore the model of language implicit in NLS, the kinds of resources it generates and the ways in which this creates failure in pupils from different language backgrounds. It then considers the New Literacy Studies and their implications for an alteration in our approach.

8mm微波辐射对小鼠运动能力影响的初步研究

目的：探讨通信微波对生物运动能力的影响效应。方法：将小鼠暴露于通信微波(波长8毫米，频率35．6GHz，平均功率密度7．4—29．4mW/cm2)，比较观察小鼠游泳耐力、血液中白细胞凋亡率及小鼠血乳酸、血红蛋白含量及血浆中SOD水平的变化。结果：经微波连续暴露后，小鼠游泳时间较对照组有缩短的趋势，达到显著性差异，SDH、LDH活性下降。运动后小鼠血乳酸比对照组显著增加。结论：通信微波可以通过多种途径影响生物的运动能力。
