This paper presents a single-country case study of the use of large scale assessment (LSA) data to generate actionable knowledge at school and system levels. Actionable knowledge is data-informed insight into school and system processes that can be used to direct corrective action. The analysis is framed from the perspective of the country’s evolving national policy on data use for educational improvement between 1990 and 2013. Trinidad and Tobago first participated in international large scale assessments (ILSAs) in 1991 but also developed a centralized system of national large scale assessments (NLSAs) in 2004. Analyses of both datasets consistently pointed to low quality and high inequality as the main actionable issues in the education system. NLSA data also hinted at notable variation in performance across schools and education districts. Analyses for and of policy point to the need for multiple school performance measures to better inform site-based, formative action. Over the period, actionable knowledge appears to have had greater impact at school level, with evidence being used by some low-performing schools to improve. However, at the system level, the frequent non-use and misuse of actionable knowledge suggest the need to promote and strengthen structures and processes related to evidence-informed policy-making.  相似文献

罗杰斯的“人格理论”是美国人本主义心理学的重要组成部分,人本主义心理学中对人的潜能给予了较高的评价,在这个前提下,罗杰斯的“人格理论”对人类的学习行为进行了深入的研究,其中“非指导性教学”、“自由学习”以及“学生中心教育”等观点对我国的素质教育有一定启发意义,值得我们学习和借鉴。  相似文献

以张作霖为首的奉系集团与日本之间关于满蒙铁路问题展开的交涉是探究日奉关系中最为复杂和突出的一个问题。铁路问题不仅是经济问题,更涉及到政治、军事利益,反映出当时的社会动态。日奉双方围绕满蒙铁路交涉的合作利用、利害冲突具有很大的代表性。纵观当时国内外形势,联系路权外交的重要影响,可以更准确地评析日奉之间的微妙关系。  相似文献

An important issue in the development and implementation of technology education curricula in Victoria is the extent to which environmental and societal issues related to technology are being addressed in the teaching of technology studies. This paper reports on the preliminary phases of a study which is intended to evaluate these aspects of technology education and describes the development of an instrument for use with practising year 11 and 12 technology studies teachers. The instrument sets out to measure teachers' attitudes towards (1) environmental and societal issues and (2) whether such issues should be taught within technology studies, as well as to investigate the extent to which such issues are actually taught in practice. In order to develop the initial version of the instrument, twenty practising technology studies teachers in Victoria were interviewed in order to ascertain their ideas about environmental and societal issues as well as to gather some initial data on the major questions.  相似文献

New public management and increasing levels of competition driven by global rankings are bringing the managerial practices of public and private higher education institutions closer together. However, these two types of institutions still maintain different objectives and traditions and enjoy different degrees of autonomy that are reflected in their internal organisational structures. We study the relative efficiency and productivity performance of private and public universities in Spain through two adaptations of the Malmquist Index. Results show that, in 2009/2010, the greater flexibility of private universities meant a better adjustment between inputs and outputs in the private sector. However, in 2013/2014, public universities had caught up with private universities. Because of the economic crisis, the inputs of public universities have decreased, but this decrease had not fully impacted their results in 2013/2014.  相似文献

This paper reviews the work on gendered achievement in the English‐speaking Caribbean, with its often explicit focus on underachieving males. However, patterns of gendered achievement are more likely region‐specific and variegated in some contexts. In Trinidad and Tobago, the full‐scale implementation of national assessments in 2004 provided an opportunity to evaluate mathematics and language performance across the entire pupil population at standards 1 (7‐ to 8‐year‐olds) and 3 (9‐ to 10‐year‐olds). Census data from the high‐stakes 2003 Secondary Entrance Assessment (SEA) administered at standard 5 (ages: 10–11+) were also included in the analysis. Therefore the entire dataset consisted of 52,284 primary school students (26,574 males and 25,710 females). The findings confirmed that female pupils had a statistically significant advantage on all assessments. However, in terms of practical significance, most differentials were negligible to small. Medium‐sized differentials were obtained for pupils of low ability, living in rural educational districts, and on language arts. Male achievement scores were also more variable for lower grade levels, low ability groups and language arts. Paradoxically, in some educational districts secondary school placement opportunities still favoured males. These variegated patterns of gendered achievement may be associated with differences in institutional effectiveness and variations in male socialization practices that are especially evident across the urban–rural divide.  相似文献
