The declining significance of homohysteria for male students in three sixth forms in the south of England

English schools have traditionally been institutions with high levels of homophobia. This is attributed to the need that heterosexual boys have to maintain a heteromasculine identity. However, by drawing on 44 in‐depth interviews and 12 months of participant observation across three sixth forms, I detail the ways in which homophobia holds little cultural sway with the heterosexual male students in these settings. Here, the majority of students intellectualise pro‐gay attitudes, maintain friendships with openly gay students and are physically tactile with each other. Homophobic discourse is rarely heard and it is even stigmatised in two of the settings. Homosexually‐themed language that I call ‘gay discourse’ replaces it. This discourse maintains socio‐negative effect, but it is also used by openly gay students to bond with their heterosexual peers. Accordingly, this research shows that cultural homophobia maintains less significance than has been documented in previous studies.

英国第六学级的职业教育

英国的第六学级历史悠久,在漫长的发展过程中,其办学职能、类型、学制和课程体系等经过数次变革,从形式到内容都打上了许多现代印迹.英国的第六学级在今天以其崭新的面貌呈现在世人面前.21世纪初,英国又把调整职业教育中的"普通国家职业资格证书",建立学术教育和职业教育之间的等价性,促进职业教育和学术教育的有机融合作为第六学级课程体系改革的重要目标.     

Low cost demonstration experiment Lorentz force: Change in path of charged particles in magnetic field

The path of charged particles is affected when they enter a magnetic field. This change of path largely depends on the angle between the applied magnetic field and the direction of motion of the charged particle (and its velocity) entering the magnetic field. This is demonstrated by means of a simple, low-cost experiment. A high voltage is used to ionize the air between a spark gap. The flow of charged particles between the spark gap is altered by applying a magnetic field from a rare earth permanent magnet having surface magnetic field induction of 0.12 T.     

浅析广西龙滩移民消费生活方式的变迁——以连迁移民新村为例

2001年7月龙滩水电站的建设促使移民的消费生活方式发生了前所未有的变化,消费种类的增加,新的消费形式不断引进,表明壮族移民的消费水平有了很大的提高,同时也出现了一些随龙滩水电站建设而来的与现代化不相符的消费行为,这应引起我们的重视,给予正确引导,确保移民的可持续发展。     

Coordination of perspective by sixth graders and teacher trainees

Sixth grade students were compared by sex for their performance on two perspective coordination tasks. Responses were compared with understanding of the principle that still water remains invariantly horizontal. Forty-eight randomly selected sixth grade students (24 girls and 24 boys) and 12 college women were individually shown a standardized three-dimensional scene. While seated in a single position, subjects completed two tasks: (1) selecting from a set of 12 pictures (displayed together) the one which could be seen from each of eight positions marked on the displayed scene and (2) choosing the positions from which could be seen eight of the 12 pictures (shown one at a time). Four of the 12 pictures were mirror images which were impossible views. Males outperformed females on both of the coordination-of-perspective tasks. For both males and females, choosing the place was more difficult than choosing the picture. Strong relationships were found between understanding of horizontality and performance on the perspective tasks. Selection of mirror images (impossible views) indicated more understanding of perspective than other, less systematic errors. Finally, female teacher trainees performed only marginally better than sixth grade students, suggesting possible remediation needs.

Strategies for academic engagement perceived by Finnish sixth and eighth graders

This study explores strategies students use to construct their academic engagement in the social environment of school. The study is based on group interview data collected from 161 sixth (78) and eighth (83) grade students. Students reflected both engaging and disengaging episodes. Data were content analysed. The results show that students reported using only confirming strategies in teacher–student interaction. More diverse strategies were described in relation to peer interaction. The results indicated that simultaneously maintaining functional peer relations and engaging effectively in academic activities is a highly challenging task which requires strategic flexibility and self-regulative skills. In terms of the development of more engaging learning environments for students, our results suggest that more attention should be paid to creating positive opportunities to participate, in terms of both academic activities and peer interaction.
