Abstract

The purpose of this article is to highlight key findings from a study of 24 early childhood preservice teachers as they moved away from a reliance on traditional interpretations of child‐centered curricula toward one of collaborative inquiry. Participants enrolled in a 15 week undergraduate teaching methods course were assigned to teaching teams to implement collaborative projects with the same group of 3–5‐year‐old children. The study utilized both quantitative and qualitative measures to assess conceptual level, changes in reflectivity, and inquiry‐oriented teaching. Results suggest that the emergence of collaborative inquiry among preservice teachers is a dynamic and diverse process not readily assessed by static measures or discreet skills. Collaborative projects did provide a context for creating communities of learners within which time, space and opportunity to practice, reflect and use language and other tools contributed to young teachers’ development of inquiry.  相似文献

ABSTRACT

Previously, heavy use of biocides for the treatment of objects made of organic materials in museum collections (e.g. ethnographic, historical collections) was very common. Now suitable decontamination methods/technologies are being sought. A decontamination treatment by li-CO2 was optimized that considered the specific requirements of museum objects. The treatment was tested on model materials artificially contaminated with biocide solutions containing dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and permethrin or cypermethrin. High decontamination was achieved for DDT, lindane, PCP, and permethrin on artificially biocide loaded wool and wood model materials. Optimal process parameter settings for li-CO2 decontamination include a single 30?min cycle for woolen materials and three sequential 30?min cycles each for wood. These methods allow a reduction of at least 90% of all biocides for wool and between 70% and 85% for wood. Decontamination of the latter was more effective for less polar biocides as DDT and permethrin. Despite a significant improvement in decontamination for wood using co-solvents such as acetone, ethanol, and methyl tertiary-butyl ether (MTBE), their use is not recommended due to the increased risk of damage to the objects, in particular if a surface coating is present.  相似文献

ABSTRACT

Existing histories of social mobility have focused on adults and on measuring the achievement of individual upward mobility. However, children and families were central to mobility strategies. Using the papers of the Heywoods of Bolton, this article examines how the families of the industrial middle class endowed their offspring with the goods and character needed to secure their social standing, highlighting the emotional intricacy of these processes. It demonstrates that such families conceived of social mobility as a familial project and that rather than pursuing upward mobility, their chief objective was to guard against social decline.  相似文献

ABSTRACT

Studies that have analysed the association between the different movement behaviours and fundamental movement skills (FMS) have considered it in an independent manner, disregarding the compositional nature of 24-h movement behaviours (24-h MB). The aim of this study was to investigate the relationship between the 24-h MB and FMS in preschoolers using a compositional data analysis . Two hundred and four preschoolers (4.5 ± 0.8 years old; 101 boys) provided objectively assessed physical activity (PA) and sedentary behaviour (SB) data (Actigraph wGT3X), and FMS (TGMD-2). Sleep duration (SD) was reported by parents. Association of daily composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When considered as a 24-h MB composition (PA, SB and SD), adjusted for age, BMI and sex, the composition predicted locomotor (r2 = 0.31), object control (r2 = 0.19), and total motor score (r2 = 0.35), respectively (all P < 0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. Achieving adequate balance between movement behaviours over the 24-h period, and its relationship with locomotor and object control skills should be considered and further investigated in early childhood.  相似文献

Students with LD who struggle with reading comprehension can benefit from instruction on how to read strategically. One strategy that has been demonstrated to increase reading comprehension is self‐questioning. In this study, two fifth graders with LD were taught to self‐generate questions using a prompt fading procedure. The participants were provided with expository reading passages with embedded questions. As each participant demonstrated proficiency with answering the embedded questions correctly, the embedded questions were systematically faded and replaced with a prompt for the students to generate their own questions. A multiple baseline across participants design demonstrated that the self‐questioning intervention resulted in improvements in reading comprehension for both students. Additionally, the students demonstrated evidence of maintenance and generalization of reading comprehension outcomes.  相似文献

In the Greek publishing industry, tradition and the desire for innovation go hand in hand. The industry is influenced by European developments in publishing and bookselling in terms of book promotion methods, the role of chain bookstores and the impact of information technology. Greece shares the features of other small book markets in Europe, whilst retaining the individuality defined by the Greek language and the country’s cultural and social conditions. This article provides an overview of the publishing industry in Greece through a review of the relevant literature and the available statistics. This work also focuses on the need to develop publishing skills through publishing education and continuous professional development.  相似文献
