Analyses of the game Spore have centered on the important issues of accuracy of evolution content and engendering interest in science. This paper suggests that examination of the degree of scaffolding necessary to use the game in pedagogy is a missing part of the discussion, and then questions the longevity of the Spore discussion relative to the general dissatisfaction with the science presented in the game. The paper proposes that analysis of Spore and other technological tools in science education may be embedded in an historical moment which directs the discussion towards satisfying sociocultural and organizational needs and away from pedagogical ones.  相似文献

The article reviews the debates and policies on access to public-sector information (PSI) in Europe in relation to the contests between policies of open access, rights of access to PSI by citizens and business, and the assessment of the cost benefits of PSI to the economy and society. The political dimension of these debates within the European Union is highlighted to demonstrate the complexities of the governance of information within a pan-European regulatory framework.  相似文献

Assessing silent reading fluency in classroom environments is challenging. This article reports on a method of assessing silent reading using underlining, an approach that solves many problems other silent reading fluency assessment measures face. This method computationally monitors readers' silent reading fluency by the speed they underline words in a text. Traditional silent reading fluency measures were compared with the new underlining methodology. Fourth‐ and sixth‐grade students completed silent reading fluency measures (i.e., moving windows, underlining, and paper‐and‐pencil reading tasks), along with measures of their oral reading fluency, reading comprehension, and vocabulary knowledge. Strong alternate‐form reliability coefficients were found for underlining, which significantly correlated with other measures of silent reading fluency and reading comprehension. Underlining methodology also correlated with common language factors, such as word length and word frequency. Together, these results provide support for the psychometric properties of underlining and suggest that it is a promising alternative method of assessing silent reading fluency. © 2012 Wiley Periodicals, Inc.  相似文献

Abstract

Purpose: This article analyses the role, approach, issues and opportunities faced by non-governmental organisations (NGOs) in the promotion of agriculture in Timor Leste from independence through to the countrywide roll out of a public extension service in 2009.

Design/methodology/approach: The research draws on semi-structured interviews with NGO personnel, local, national and international, actively involved in agricultural development to ascertain how organisations engage with communities, their objectives, inputs, coverage and impacts. The analysis is based on the framework developed by Birner et al. (2009) for pluralistic advisory services, and the discussion is framed by contemporary NGO discourse.

Findings:This article argues that NGOs have a central role in agricultural development, with particular advantages that can be built upon, however there must be explicit acknowledgement of the complex nature of the NGO and civil society, and a critical awareness of the need for strategic thinking, communication and coordination for effective aid.

Practical implication: NGOs play a central role in agricultural development. There is a need for a more nuanced understanding of the opportunities and limitations of the NGO sector, both as service providers but also more broadly as part of civil society.

Originality/value: Funding directed to the NGO sector for implementation of development projects is prolific. There is substantial discourse on partnerships between NGOs and other actors. However, little of the debate appears within discussions on agricultural service provision.  相似文献

Body composition measures were collected pre‐, mid‐ and post‐season on a team of eight national‐calibre collegiate women gymnasts to examine intraseason changes. Also analysed were interseason changes using pre‐ and post‐season data on five of the eight subjects during the current and previous year, according to a 2 x 2 (years x tests) analysis of variance repeated‐measures design. Skinfold, circumference and diameter measures were collected with percentage body fat, lean body mass and body density determined by regression equations developed specifically for collegiate female gymnasts.

Intraseason body weight decreased significantly from pre‐ to mid‐season (x = 55.0 and 53.6 kg respectively); but the difference between mid‐ and post‐season (53.9 kg) values was not significant (P>0.05). The majority of the 1.4 kg weight loss occurred during intense pre‐season conditioning and not during the actual season. Percentage body fat, on the other hand, decreased significantly from pre‐to mid‐season and mid‐ to post‐season (x = 21.4%, 17.4% and 13.45% respectively; P<0.0005). Body density increased significantly from pre‐ to mid‐season and mid‐ to post‐season (x = 1.0476, 1.0584 and 1.0681 respectively; P<0.0005). Of the circumference and skinfold values used in calculating percentage body fat and body density, only the skinfold values displayed significant decreases throughout the season.

Interseason analyses revealed no significant changes in any of the dependent measures between seasons, despite consistent trends. There were no significant years x tests interactions and all intraseason changes for two seasons (n = 5) were the same as those found in more detailed analysis of a single season (n = 8) except in the case of weight loss, which was marginally significant (P < 0.046) in the single‐season and not in the dual‐season analysis (P>0.05).

Body composition of these gymnasts changed in many ways within competitive seasons. The most pronounced changes observed were decreases in subcutaneous fat and increases in body density. This study reinforces the need for administrators, coaches and athletes to be concerned with percentage body fat and skinfold measures rather than weight alone when determining if a person is ‘fat’.  相似文献

Deviations from perfect bilateral symmetry, in a normally symmetric organism, signal a lack of developmental precision. In adult human males, previous studies have shown that symmetry is positively associated with height, body mass and physical performance. In this study, symmetry was measured in adult male athletes from two sports, competing at two different standards. Fifty-two elite and sub-elite Australian male basketballers and soccer players, who regularly competed in the national and state leagues in the 2000-2001 season, participated in the study. All participants underwent anthropometric assessment. Both basketballers and national league athletes in general were significantly taller (P < 0.0001) and heavier (P < 0.001) (and more ectomorphic in the case of basketballers) than their soccer-playing and state league counterparts, respectively. The anthropometric traits were examined further for departures from perfect bilateral symmetry. No significant differences in size-corrected asymmetry were observed between the two competitive standards (P > 0.50), the two sports (P > 0.50) or among any of the competitive standard x sport groups (P > 0.50). Contrary to expectations, we did not find any differences in asymmetry between adult male athletes from two sports (basketball and soccer), competing at two different standards (professional national league and semi-professional state league).  相似文献
