Primary Considerations for Primary TEFL in China

This article will focus on five key areas relating to Primary TEFL in China.Firstly,the real TEFL context in Chinese primary schools will be discussed in terms of its special characteristics.Secondly,the current methodological approach will be examined from both a theoretical perspective,focusing on government(MOE)policy for primary TEFL,and a practical perspective,based on personal observations of classroom practice.The third section of the article will highlight some perceived shortcomings of current practice,while the fourth will outline the actual needs of primary learners in the Chinese educational system.Finally,the question of how teachers can meet these needs will be examined in relation to:methodological integration; integration of skills and sub-skills teaching/learning;and the exploitation of materials and activities to provide learners with three different types of language input and output opportunities(extensive,intensive and analysed:Swan,2006).     

The construction of abstract units in geometric and numeric settings

The main thesis of this paper is that the construction and coordination of abstract units is central to mathematical activity in both numerical and geometric settings. Data were gathered from students in grade three through six, with four students being observed over a three year period. A consistent parallel was found in the sophistication of the types of units constructed in a geometric setting (tiling the plane) with their numeric activity. The tiling activity of the students was analyzed for evidence of the construction and coordination of units. Some students constructed rather sophisticated abstract composite units to facilitate their tiling with a particular shape while others had difficulty making a covering. Students who constructed abstract composite units in tiling did so also in adding and subtracting whole numbers. Evidence of unitizing and coordinating the units constructed was associated with advances in mathematical thinking. Unitizing seems to be a fundamental mental operation in coming to act mathematically. As mathematics activities are planned, it is important to provide opportunities for students to construct abstract composite units in both geometric and numeric settings. Emphasis on prescribed procedures such as subtracting with two-digit numerals may inhibit this construction process.     

Consistency and variability of learning strategies in different university courses

The present study addressed the question of consistency and variability in learning strategies. Four university courses provided different learning contexts. The same group of students reported about their learning strategies by completing identical questionnaires on each of these courses. Participants were 85 students attending the first year of Law studies. A second study consisted of 63 students attending similar courses in the following academic year. An analysis of variance showed that students varied their reported learning strategies as a function of different learning contexts. This indicated a context-specific component in strategy use. Intercorrelations, however, showed that students displayed consistency in reported learning strategies across course contexts as well. This indicated a personal, habitual component in strategy use. It thus seems that the question of variability and consistency in learning strategies does not yield an either-or, answer. Context variables were explored to explain the variations. Use of stated cases, provision of a clear organisation of subject matter and of diverse didactic resources appeared to diminish encountered problems and lack of regulation (which proved to be related variables), and promote the use of concrete processing, relating, analyzing, self-regulation and externally regulated strategies. Evidence was found that learning strategies differed among each other in the degree of variability. Memorizing turned out to be relatively resistant to differences in course context, whereas concrete processing strategies and lack of regulation showed relatively large susceptibility to course context. Explanations were proposed in terms of different stages in the development of learning strategies and in terms of context-variables.     

Childcare Food Handling Employees’ Perceived Barriers and Motivators to Follow Food Safety Practices

Each year millions of children are enrolled in center-based childcare. Childcare employees are tasked with handling over half the children’s weekly meals. Proper food handling practices are crucial in mitigating this high-risk population’s risk of foodborne illness. The purpose of this study was to identify childcare food handling employees’ (n?=?278) perceived barriers and motivators to follow recommended food safety practices. Six important barriers and 14 key motivators to following recommended food safety practices were identified. Important barriers pertained to time restraints, workloads, and lack of understanding of the importance of following proper food safety practices. Key motivators were focused on children’s safety, available supplies, communication, and food safety training/information. Employee and facility characteristics were shown to influence perceived importance of barriers and motivators to following food safety practices. Childcare directors should review scheduling and job duties of employees as the majority of identified barriers focused on “work pace” and “time restraints.” Directors should also attempt to increase food safety communication through practical situational training, written food safety policies, and use of food safety signage to increase understanding of the importance of proper food safety practices. Ensuring proper supplies are available is necessary.     

Scaling and Sustaining Effective Early Childhood Programs Through School–Family–University Collaboration

We describe the development, implementation, and evaluation of a comprehensive preschool to third grade prevention program for the goals of sustaining services at a large scale. The Midwest Child–Parent Center (CPC) Expansion is a multilevel collaborative school reform model designed to improve school achievement and parental involvement from ages 3 to 9. By increasing the dosage, coordination, and comprehensiveness of services, the program is expected to enhance the transition to school and promote more enduring effects on well‐being in multiple domains. We review and evaluate evidence from two longitudinal studies (Midwest CPC, 2012 to present; Chicago Longitudinal Study, 1983 to present) and four implementation examples of how the guiding principles of shared ownership, committed resources, and progress monitoring for improvement can promote effectiveness. The implementation system of partners and further expansion using “Pay for Success” financing shows the feasibility of scaling the program while continuing to improve effectiveness.     

加拿大高等学校的网络教育

线性时态逻辑的决策问题复杂性

不同的时态逻辑能够适应不同的推理任务.为了符合应用,关于时间的模型从离散的自然数和整数,延伸到稠密的线性实数,甚至扩展到区间代数和树代数.如果简单的时态连接词的表达力已经足够,就只需使用这些简单的时态连接词来构造的时态逻辑.在能够承担降低运算速度的风险下,我们可以为实现更强的表达力而使用更多的连接词,也可以加上度量信息或者固定点.作者近期提出了一个令人惊讶的结论:建立在实数时间上的具有足够表达力的语言和基于自然数离散时间流的传统简单算子,它们推理的计算复杂性是一样的.在这篇论文中,作者试图对建立在标准时态连接词和线性时间流的普通类上的时态逻辑中所有决策问题的计算复杂性作新的说明.尤其是,文中指出,所有标准逻辑在PSPACE中都存在决策问题.
