It was the purpose of this investigation to examine the effects of living with a male or female head-of-household upon the arithmetic performance of fourth graders. No significant differences were found in mean scores between male and female pupils. Significant differences were found favoring those pupils living with male heads-of-households, particularly for female pupils and for pupils with IQ scores greater than 100. These findings should not be considered as simple cause and effect relationships, but rather as indicative of potential difficulty for some pupils. 相似文献

One impact of globalisation has been the expansion of higher education to meet changing current socio‐economic and political requirements. This expansion places considerable stress on the public purse and many states have turned to alternative solutions. In China, a new phenomenon has emerged: independent higher education institutions that complement public and private institutions in helping to cater for the expanded numbers of students. These independent institutions are formed through partnerships between existing institutions and the business sector. After analysing the political, socio‐economic and cultural contexts that shape the policy of developing independent institutions, this paper explores the dilemmas and challenges that have arisen at the implementation level and critiques some of the solutions that have been found. 相似文献

Using a participatory learning approach, we report on the delivery and evaluation of a climate change and risk assessment tool to help manage water risks within the agricultural sector. Post-graduate water-professional students from a range of countries, from both developed and emerging economies were involved in using this tool. Our approach included participative learning tools – group discussion, software, and risk matrices. The materials developed met the needs of the students, allowing these students to incorporate their learning and adapt the package of materials for use in their home countries. Analysis of evaluations show that the tools and materials are particularly useful and emphasizes the need for sound learning materials and tools, funding to deliver training, and policy support to accelerate education and adoption of authentic climate change adaptation practices. The expected benefits for water professionals about climate change will be translated into improved socioeconomic and environmental outcomes if adopted. 相似文献

This article responds to attitudes about giftedness in M. Sapon‐Shevin's article, “Explaining Giftedness to Parents: Why it Matters What Professionals Say.” Giftedness is not a reward or a privilege, but an aspect of a child's individuality that should be understood and taken into account by the educational system. Gifted children's needs are not solely academic, and it is parents who are responsible for meeting those needs. They need information from as many sources as possible. They are also excellent sources of information themselves, so the relationship between professionals and parents should be reciprocal. This article also responds to some of Sapon‐Shevin's objections to the book Guiding the Gifted Child, (Webb, Meckstroth, Tolan, 1982). In the preparation of this article, the writer worked closely with coauthors James T. Webb and Elizabeth Meckstroth, whose pioneering work with the SENG Project at Wright State University provided the basis of Guiding the Gifted Child. 相似文献

This study investigated the evolution of physical and technical performances in the English Premier League (EPL), with special reference to league ranking. Match performance observations (n = 14,700) were collected using a multiple-camera computerised tracking system across seven consecutive EPL seasons (2006–07 to 2012–13). Final league rankings were classified into Tiers: (A) 1st–4th ranking (n = 2519), (B) 5th–8th ranking (n = 2965), (C) 9th–14th ranking (n = 4448) and (D) 15th–20th ranking (n = 4768). Teams in Tier B demonstrated moderate increases in high-intensity running distance while in ball possession from the 2006–07 to 2012–13 season (P < 0.001; effect size [ES]: 0.68), with Tiers A, C and D producing less pronounced increases across the same period (P < 0.005; ES: 0.26, 0.41 and 0.33, respectively). Large increases in sprint distance were observed from the 2006–07 to 2012–13 season for Tier B (P < 0.001; ES: 1.21), while only moderate increases were evident for Tiers A, C and D (P < 0.001; ES: 0.75, 0.97 and 0.84, respectively). Tier B demonstrated large increases in the number of passes performed and received in 2012–13 compared to 2006–07 (P < 0.001; ES: 1.32–1.53) with small-to-moderate increases in Tier A (P < 0.001; ES: 0.30–0.38), Tier C (P < 0.001; ES: 0.46–0.54) and Tier D (P < 0.001; ES: 0.69–0.87). The demarcation line between 4th (bottom of Tier A) and 5th ranking (top of Tier B) in the 2006–07 season was 8 points, but this decreased to just a single point in the 2012–13 season. The data demonstrate that physical and technical performances have evolved more in Tier B than any other Tier in the EPL and could indicate a narrowing of the performance gap between the top two Tiers. 相似文献
