Boys go fishing,girls work at home: gender roles,poverty and unequal school access among semi-nomadic fishing communities in South Western Madagascar

Drawing from data gathered in South Western Madagascar in 2011, the work explores the combination of poverty and traditional gender roles as a critical factor in determining unequal school access among young people from semi-nomadic fishing communities. It demonstrates that from the age of early puberty, most boys go fishing with their fathers and brothers whilst most girls from the same families work at home. In contrast to the school systems observed in many developing society contexts, which demonstrate female marginalisation, in South Western Madagascar both boys and girls are marginalised. Instruments of global policy designs, such as positive discrimination for girls, seem ill-suited to resolve the problem. Instead, the authors call for a more tailored and context-specific approach to address the particular challenges amongst semi-nomadic fishing communities in Madagascar.     

委婉语的认知语言学分析

Effects of Diagrams on Mathematics Performance

Research on the facilitative effect of diagrams on solving mathematics problems is both inconsistent and inconclusive. This study investigates the effects of diagrams on 124 Singaporean pupils in three classes: Primary One and three, and Secondary One. Pupils' performance was measured with the use of teacher-written mathematics problems in the form of worksheets. Number of errors made on problems accompanied with and without diagrams were compared. Whether or not pupils benefit from diagrams was estimated by their patterns of errors made in the presence or absence of diagrams. Results both confirm and disconfirm previous findings and shed further light on the use of diagrams in mathematics.

利用黄昏时段,提高幼儿交往主动性的行动研究

从幼儿长远的发展来看,交往能力的培养是非常重要的一个方面,也是我国幼儿园教育的目标之一。幼儿交往主动性相对较差是我们这个日托、寄宿混合幼儿园普遍存在的一个问题,而在黄昏时段幼儿的情绪波动最大,在交往方面存在的问题尤为突出。本课题采用行动研究法,通过改善黄昏时段幼儿园的活动和环境,来改善幼儿的在园情绪和交往的主动性,从而提高幼儿在日常生活中的交往主动性。研究结果显示:幼儿在与客人、教师、同伴等不同群体交往方面的主动性都有了显著的提高,在矛盾冲突的主动解决等方面也有了一定程度的改善。

公司责任主体认定法律制度研究——评加拿大刑法典草案C-45

公司刑事责任,尤其是外国公司刑事责任是对目前越来越多以公司名义触犯刑法的法律管制.我国<刑法>对公司犯罪相应法律责任的承担作了一些原则性的规定,但是其体系尚不健全,导致实际中出现的涉及到在华投资的外国公司犯罪的案子难以得到清楚和有效的法律指引.本文拟借他山之石,详细分析加拿大刑法典修改草案C-45中对公司刑事责任的规定,以期抛砖引玉,为中国法制建设增光添彩.

Building preschool teachers’ capacity for teaching Chinese to ethnic minority children in Hong Kong: A qualitative study

ABSTRACT

Teaching Chinese to second language learners is a challenge for preschool teachers in Hong Kong so effective teacher professional development programmes are urgently needed to enhance their knowledge and skills. An Integrative Model Teacher Professional Development Programme which incorporates three theoretical underpinnings (i.e., culturally responsive teaching, meaningful and pleasurable learning, and effective teaching of Chinese as a second language) is designed to equip preschool teachers with knowledge, skills, and awareness in teaching Chinese to ethnic minority students. Through qualitative interviews with 15 in-service preschool teachers who joined the Programme, teachers’ perceptions and changes in three theoretical areas of teaching Chinese to ethnic minority students were explored. Particularly, teachers increased their awareness of ethnic minority cultures, developed empathy with ethnic minority children and their families, gained knowledge of implementing culturally responsive teaching and meaningful and pleasurable learning of Chinese. The role of teacher sharing in effective professional development was highlighted.
