一向与机械化过不去的Jim,现在开始明确表示了他对机械化的厌恶和感想,要知道,在别人的手里能够运行很好的机器只要一到Jim的手里,定然闹别扭,当然这也不是一般人所能学来的本领哦。让我们来看看他是怎么说的吧。  相似文献

The article systematizes the results of an autoethnography that aimed at understanding the difficulties of the collective work of teachers, their culture and their experience in the context of a municipal public school in Porto Alegre, Brazil. The autoreflexive exercise showed that urban violence leaves profound marks on the culture of the local community, and generates effects on the subjectivity and organization of the work of teachers in this school community.  相似文献

Effective behavior support is an important component of high-quality and nurturing early childhood classroom settings. At present, there are few studies that investigate the best way to train and support teachers in these strategies. The present study compared two different training approaches: (1) a workshop that included a one-day classroom-based training that introduced effective preventative and behavior support strategies followed by school year behavioral consultation support; or (2) an intensive condition that included the one-day workshop plus four days of experiential learning and practice in a preschool classroom followed by school year behavioral consultation support. Eighty-eight teachers/aides were randomly assigned to one of the two training conditions, and training occurred in August before the commencement of the school year. Results indicated that on observations of effective behavioral management and instructional learning formats, teachers in the intensive condition were improved proximally, with effects waning over time. For measures of teacher use of praise, the intensive group maintained the improved rate throughout the school year relative to the workshop group. Rates of commands and observations of classroom productivity were not different between groups. Teachers were satisfied with both approaches to training.  相似文献

This article examines the question: Do lexical, syntactic, fluency, and discourse measures of oral language collected under narrative conditions predict reading achievement both within and across languages for bilingual children? More than 1,500 Spanish–English bilingual children attending kindergarten–third grade participated. Oral narratives were collected in each language along with measures of Passage Comprehension and Word Reading Efficiency. Results indicate that measures of oral language in Spanish predict reading scores in Spanish and that measures of oral language skill in English predict reading scores in English. Cross‐language comparisons revealed that English oral language measures predicted Spanish reading scores and Spanish oral language measures predicted English reading scores beyond the variance accounted for by grade. Results indicate that Spanish and English oral language skills contribute to reading within and across languages.  相似文献

The aims of this study were: (i) to determine kinematic, kinetic, and electromyographic characteristics of Junzuki karate punch in professional karate athletes; (ii) to identify biomechanical parameters that correlate with punch force and lead to a higher punching performance; (iii) to verify the presence of muscle co-activation in the upper limb, trunk, and lower limb muscles. Data were collected from nine experienced karatekas from the Accademia Italiana Karate e Arti Marziali during the execution of the specific punch. Mean punch forces (181.2?N) delivered to the target, the range of motion of both right and left knees (1.13 and 0.82?rad) and right elbow (1.49?rad) joints, and the angles at impact (knee: 0.81 and 0.91?rad; elbow: 1.19?rad) in the sagittal plane were computed. Furthermore, the trunk rotational angular acceleration (63.1?rad?s?2), force related to the lower limbs (550.2 and 425.1?N), and co-activation index for the upper limb (36.1% and 34.7%), trunk (24.5% and 16%), and lower limbs (16.0% and 16.1%) muscles were evaluated bilaterally. Significant positive correlations were found between the punch force and both right and left knee flexion at the instant of impact and right and left leg force. Significant negative correlation was found between the punch force and maximum trunk angular acceleration. Significant differences (p?=?.03) in the co-activation index among the upper limb, trunk, and lower limbs muscles highlighted a rostro-caudal gradient on both body sides. This research could be of use to performers and coaches when considering training preparations.  相似文献

This article reflects on six years of research activities in the field of long‐distance collaboration and more specifically on how creative virtual teams operate and respond to challenges set by emerging and developing technologies. Furthermore, it considers how to build, manage and shape a more inclusive virtual team, documenting the methodologies applied in each activity, the experiences of both tutors and students and the educational context in which the international study took place. The project set out with a methodology for observing, managing and developing the interaction dynamics between each creative team member involved in the design of activities and practice of delocalized teams. The project is positioned within the field of educational technology and identifies a set of operative recommendations aimed at educators so that remote creative collaborative work can result most effective. The article explores the potential of virtual teams supporting communication and design.  相似文献
