Research to date has not been able to agree whether visuo-spatial ability can be influenced through practice. Many have concluded that spatial awareness is an innate phenomena and cannot be learned. Others contend that an individual's visuo-spatial potentials are acquired through interactions with the environment. Many of these theorists believe that spatial thinking can be developed through interactive exercises devised to encourage mental image formation and manipulation. To help alleviate the confusion surrounding this question the following study was undertaken. Eighty-four college undergraduates were randomly placed into control and experimental sections. Student records were examined to assure that the groups did not differ significantly in their verbal or math proficiency and pertinent pretests were given to ascertain spatial levels. The groups were also similar on their male and female ratios. During the semester the experimental section was treated to a 30-minute interaction each week. These sessions involved spatial exercises that required the participants to mentally bisect three-dimensional geometric figures and to envision the shape of the two-dimensional surface formed by the bisection. The subjects drew their mental image of this surface on a sheet of paper. Fourteen weeks later both groups were post tested with a second comparable version of the pretest. Statistical “t” tests were performed on the group means to see if significant differences developed between the sections. The results indicate that statistical improvement in visuo-spatial cognition did occur for the experimental group in spatial visualization, and spatial orientation. This finding suggests that the weekly intervention sessions had a positive effect on the students' visuo-spatial awareness. These results, therefore, tend to support those researchers that claim visuo-spatial aptitude can be enhanced through teaching.  相似文献

As schools attempt to address the needs of an ever more diverse student population, many have turned to intensive interventions to improve reading performance. Reading First grants from the United States Department of Education encouraged schools to implement evidence-based instructional practices in elementary schools. However, for many schools, implementation of Reading First and other intensive data-driven reading initiatives has not included students considered to have significant disabilities or has led to increased pull-out or separate remediation services. We consider how Reading First efforts can be integrated into a rich, inclusive education program for all students, including those considered to have the most significant disabilities. We discuss how schools can creatively utilize staff and scheduling to maximize push-in support and encourage interdisciplinary and data-driven problem solving to provide meaningful guidance for reading instruction for the benefit of all students.  相似文献

ABSTRACT

The objective of this review was to systematically describe the traditional and contemporary data capture and analytic methods employed in performance analysis research in team invasion sports, evaluate the practicality of these methods, and formulate practical recommendations on methods for analysing tactics and strategies in team invasion sports. A systematic search of the databases SPORTDiscus, Web of Science, Scopus, MEDLINE and PubMed was performed. Keywords addressed performance analysis methods and team invasion sports, with all other disciplines of sports science excluded. A total of 537 articles were included in the review and six main themes of research identified. Themes included game actions, dynamic game actions, movement patterns, collective team behaviours, social network analysis and game styles. Performance analysis research has predominantly focused on identifying key performance indicators related to success by analysing differences in game actions between successful and less successful teams. However, these measures are outcome-focused and only provide limited insight into winning team’s strategy. Team invasion sports are now viewed as dynamic, complex systems with opposing teams as interacting parts. Strategies and tactics should be analysed using a holistic process-orientated approach by recording dynamic actions, collective team behaviours and passing networks, and viewing them in game styles.  相似文献

Background: Prolonged strenuous exercise has a profound effect on cardiac function. The right heart may be more susceptible to this imposition; yet, right-sided chest leads have not been utilised in this setting. Methods: Thirty highly trained athletes at the 2014 Western States 100-mile Endurance Run from Squaw Valley to Auburn, California (body mass 68?±?12?kg, age 45?±?10?years, 57?±?15?miles per week) were recruited for the study. Pre- and post-race, a right-sided 12-lead ECG was obtained and data were extracted for P, R and S waves, J point, ST segment and T wave amplitude. Data were compared using Students T-test and statistical significance set as P?Results: There was a significant increase in P wave amplitude (29%) and QTc interval (4%) pre- to post-race from standard 12-lead ECG. From the right-sided12-lead ECG, a 23% (P?=?.01) and 38% (P?=?.03) increase in J point amplitude in V1R and V2R and a 22% (P?=?.05) increase in ST segment integral in V2R and V3R were evident. T wave inversion was evident in leads V2R–V6R in 50–90% of athletes, respectively. Close examination revealed marked heterogeneity in individual ECGs. Conclusions: Completion of a 100-mile ultra-marathon resulted in significant changes in the right-sided ECG alongside more marked responses in specific individuals. P wave, ST segment and T wave changes post-race are indicative of acute exercise-induced right heart electrical adaptation.  相似文献

Trends towards the devolution of responsibility for decision‐making to the school level are evident in education systems throughout the world. Underpinning policies of devolution are assumptions that school communities will work collaboratively to make decisions appropriate to the local context. However, collaborative processes do not occur automatically. In this paper, a case study of one school committee is presented to outline the processes used and to highlight the difficulties experienced in working collaboratively to develop a school behaviour management policy.  相似文献

The aim of this research was to develop a new questionnaire for exploring the reading beliefs of undergraduate students, because the only currently available instrument has conceptual and methodological limitations. The paper describes the process of developing the instrument and presents a range of psychometric data obtained from a sample of 558 Spanish undergraduates who were in the first or final year of a degree programme in psychology, language and literature or engineering. The results provide evidence of the psychometric quality of items and reveal a dual structure of two and six factors, both obtained through exploratory and/or confirmatory factor analyses. Adequate reliability based on internal consistency of the factors was also demonstrated. As a measure of criterion validity, differences in reading beliefs by gender, academic year and knowledge area were also explored. The findings support the psychometric adequacy of this new instrument developed through an exploratory piece of research. Overall, the process of constructing the instrument and the results from this study provide a framework for research and intervention, in addition to presenting a tool that both researchers and teaching staff could use in the context of reading and reading comprehension.  相似文献

Redesigning a curriculum for inquiry: an ecology case study   总被引:1,自引:0,他引:1  
This article reports on an interdisciplinary ecology degree that was redesigned to provide more research activity for undergraduates. A case study approach explored how the teaching team constructed a curriculum that used inquiry activities. The development of an inquiry curriculum was enabled by a University audit focusing on the links between teaching and research, a Programme Review that signalled a need for change, and a Programme Director and group of academics committed to change. In addition, curriculum planning discussions were facilitated by an academic staff developer, who developed a shared vision for an inquiry approach during extended conversations amongst the planning group. Consequently, the new programme progressively develops inquiry skills in four out of five core courses (papers/modules). At stages 1 and 2, structured, guided and open inquiry activities lead to an open inquiry capstone course at stage 3.  相似文献

Many acquisitions of high-tech firms are motivated by the acquirers' desire to enhance their strategic technological capabilities. However, these capabilities are likely to be embedded to a large degree in the tacit and socially complex knowledge of the acquired firms' individual and collective human capital. This presents a dilemma for acquirers because, unlike tangible or financial assets, the acquired firms' valuable human assets cannot be purchased or owned outright and they can leave the firm at any time. Retention therefore is likely to be of central importance during acquisition implementation in knowledge-intensive firms. Using data from a sample of acquisitions in high-technology industries, the results of this study confirm that retention of specific types of human capital is critical for determining the success of the acquirers' efforts to gain valuable new technological capabilities. Applying the theory of relative standing to predict post-acquisition retention, we find that autonomy, status, and commitment significantly affect retention, but economic incentives do not. We discuss and integrate these results in the context of knowledge-based views of the firm and the existing literature on acquisition implementation.  相似文献
