Researching undergraduate social science research

The experience(s) of undergraduate research students in the social sciences is under-represented in the literature in comparison to the natural sciences or science, technology, engineering and maths (STEM). The strength of STEM undergraduate research learning environments is understood to be related to an apprenticeship-mode of learning supported by more experienced (post-graduate) peers, often through ongoing research projects. Studies of undergraduate research reveal that this is not typical in the social sciences, and students report facing specific challenges to the development of their identities as researchers that include fear, intellectual confusion and emotional unsettlement. This paper examines how a social science learning environment, designed as a research study itself, fostered beginning researchers communities of practice, realised a distinct mode of apprenticing based on peers’ similarly peripheral community membership, and enabled students to reframe emotional unsettlement. It argues that, effectively mediated, talk can powerfully improve undergraduate social science research students’ experiences.

含西佛碱有机液晶的合成、结构及刚性实对介晶性的影响

通过相转移催化下的芳基醚合成，由对－烷氧基苯甲醛，对－烷氧基苯胺分别与对－苯二胺和对－苯二甲醛发生亲核加成反应，合成了12个中心桥连基为西佛碱，含有3个苯环，不同刚性实结构及不同末端链长的西佛碱化合物，并通过DSC和偏光显微镜对其介晶性进行了表征，研究表明，末端链长度及刚性实结构对相应变温度和清亮温度均有影响，但末端链长度对相变温度和清亮点温度影响较小，刚性实结构对相变温度和清亮点影响较大。     

Why Do Students Misbehave? An Initial Examination of Antecedents to Student Misbehavior

The current study utilized constant comparative thematic analysis to uncover antecedents of student misbehavior from the perspective of collegiate instructors. Results indicated nine distinct antecedents of student misbehavior that were classified into three distinct categories: deficiency antecedents, belief antecedents, and external antecedents. These findings extend previous research on antecedents of student misbehavior by forwarding a more nuanced classification structure that centers on attribution theory as an explanatory mechanism. Overall, by understanding the potential reasons that underlie student misbehavior, educators can create more meaningful and enriching experiences for students by thoughtfully addressing these problematic behaviors and the underlying conditions that promote them.

Empowering and protecting children by enhancing knowledge,skills and well-being: A randomized trial of Learn to BE SAFE with Emmy™

Australia needs effective programs to protect children and prevent abuse, but there is little information available for policymakers or families. Using a randomized controlled trial, Learn to BE SAFE with Emmy™, a school-based protection program for young children designed by Act for Kids, was evaluated to determine its effectiveness for promoting young children's knowledge and skills. Grade one children (n = 245) from 15 classrooms across 5 primary schools completed assessment measures. A subset of these children received the program (n = 131) or acted as a comparison group (n = 114). Parents (n = 72) completed questionnaires about their child's participation in the program. When compared with children who had not received the program, children who completed Learn to BE SAFE with Emmy™ demonstrated increased knowledge of interpersonal safety and were more likely to choose a safe response option to hypothetical unsafe scenarios 6 months after participation than at both pre- and post-intervention. Parents reported their children who participated used more safety strategies immediately and 6 months after participation compared to pre-intervention. Outcomes can assist in guiding future policies around the prevention of child abuse and protect the well-being of Australian children.     

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。
