The purpose of this study was to explore the relationships between Latino students’ learning styles and their language spoken at home. Results of the study indicated that students who spoke Spanish at home had higher means in the Active Experimentation modality of learning (M = 31.38, SD = 5.70) than students who spoke English (M = 28.08, SD = 5.36) or both languages (M = 30.79, SD = 5.93) at home. Students in all 3 groups—students who spoke Spanish, English, and both languages at home—had similar means and standard deviations in the Reflective Observation modality of learning. 相似文献

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. 相似文献

Internationally there is interest in developing the research skills of pre-service teachers as a means of ongoing professional renewal with a distinct need for systematic and longitudinal investigation of student learning. The current study takes a unique perspective by exploring the research learning journey of pre-service teachers participating in a transnational degree programme. Using a case-study design that includes both a self-reported and direct measure of research knowledge, the results indicate a progression in learning, as well as evidence that this research knowledge is continued or maintained when the pre-service teachers return to their home university. The findings of this study have implications for both pre-service teacher research training and transnational programmes. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

This paper investigates current research into the role of education in combating social injustice, assembles this research to indicate key features of a teacher education programme that would assist education for social justice, and links these features to one innovative university teacher education programme to ascertain some of the practical difficulties in establishing such a programme. The research indicated key approaches that would enhance the probability that graduates from teacher education programmes will be able to pursue social justice initiatives. 相似文献

This study aimed to use a learning inventory (the Approaches and Study Skills Inventory for Students, ASSIST) to measure the
impact of a curriculum change on students’ approaches to learning in two large courses in a health sciences first year programme.
The two new Human Body Systems (HUBS) courses were designed to encourage students to take a deep approach to learning. ASSIST
was completed by 599 students enrolled in a biology class in 2006 that was part of the old curriculum, and by 705 students
at the beginning and end of the new HUBS courses in 2007. Changes in students’ approaches to learning over time were examined.
The ASSIST scores for both HUBS courses reflected the dominance of a surface approach, followed by a strategic and then a
deep approach. However, by the end of the year, students were taking a deep and strategic approach to their studies to a greater
extent, and a surface approach to a lesser extent. Moreover, students enrolled in the new course adopted a deep approach to
their studies to a significantly greater degree than those studying the old curriculum. Despite the predominance of a surface
approach, the results suggest that it is possible to bring about small but significant positive changes in students’ learning
behaviour in a very large class through curriculum change. The proportion of students preferring a surface approach, and results
showing that high performance on the final exam was significantly correlated with a surface approach, probably reflected contextual
factors, including assessment, and is the focus of ongoing curriculum development. 相似文献

Despite widespread support for integrated approaches to teaching, classroom practice reveals a lack of implementation. This paper explores challenges and opportunities in teaching an integrated curriculum, and connects this with the contemporary notion of a twenty-first century curriculum and pedagogy. A case study of Global Education (GE) is used to delineate the complexity of issues when teachers attempt to move beyond disciplinary-based teaching approaches. We examine curriculum documents, advice for teachers on curriculum implementation, preservice teachers’ experiences in schools during Professional Experiences and national guidelines for Professional Experience. Through these data, a broad picture emerges of influences on integrating curricula in classrooms. Opportunities to integrate curriculum incorporating twenty-first century pedagogies were limited by pressures on teachers with preservice teachers rarely exposed to authentic integration. Teachers’ professional standing requires clear guidelines, which allow them to pursue important twenty-first century content and skills , for young citizens and this must begin in preservice education. 相似文献

Adequate dietary strategies are essential for the successful participation in ultra-endurance races. The aim of this study was to evaluate and compare the energy and water intakes of participants during three different mountain ultra-endurance runs. The study took place at the “Ultra Mallorca Serra de Tramuntana” (Mallorca, Spain), an ultra-endurance mountain event with runners participating either in a 44-km (Marathon, n = 51), a 67-km (Trail, n = 109) or a 112-km (Ultra, n = 53) run competition. Participants in the study answered a questionnaire focused on the nutritional intake within an hour after finishing the competition. Mean energy intake during the competitions was 183 kcal · h¯1, with an average carbohydrate intake of 31 g · h¯1 (52.1% of participants consumed less than 30 g · h¯1). No significant differences between competitions were found in these parameters. However, a higher percentage of energy from lipids in participants in the Trail and the Ultra was found (P = 0.034). Furthermore, significant differences were observed in water intake per hour of competition (P = 0.039), with the lowest value for the intake during the Ultra competition. In conclusion, the majority of the participants in the study present low carbohydrate intakes. However, fluid intake seems to be adequate. Different distances did not significantly influence the participants’ nutritional strategies. 相似文献
