The uptake and use of digital technologies is studied in Unos Umeå, a joint one-to-one (1:1) research project between Umeå University and the municipality of Umeå in Sweden. This article presents the results of the third phase of the classroom work with laptops. Using the ecology of resources model (Luckin, 2010), these possibilities and challenges can be interpreted as the manifestation of filters in the learning environment. Alleviating technical problems, targeting low student laptop use, teacher collaboration, and teacher professional development (TPD) may help teachers and students gain and sustain technology-enhanced learning (TEL) in this 1:1 initiative. 相似文献

In South Africa, freedom of information (FOI) is entrenched in section 32 of the Constitution, which guarantees every citizen the right of access to any information held by the state or by any other person that is to be used for the protection or exercise of any right. The Promotion of Access to Information Act (PAIA) is the law that gives effect to section 32 of the Constitution. Regardless of a remarkable trend towards the adoption of FOI laws, international trends have shown this does not automatically translate into fulfilment of people's right to information. This study utilised mixed method research through the explanatory sequential design to assess compliance with FOI legislation by public bodies in South Africa, with a view to develop a model for implementation of FOI. The study first conducted a quantitative study by analysing the reports of the South African Human Rights Commission from the reporting years 2006/07 to 2016/07 to assess compliance with sections 14, 15, 16, 17 and 32 of the PAIA. Thereafter, a qualitative study through interviews with purposively chosen participants was conducted to substantiate the findings of a quantitative study. Key results suggest that over the years, there were problems in the implementation of the FOI legislation in South Africa and its use was limited. Where implementation has taken place, it has been partial and inconsistent. The responsibility for the implementation of FOI legislation in most public bodies is assigned to legal departments that do not have knowledge of what records are created, and where and how they are kept. With regard to compliance, in terms of the degree of comparison, the situation was better in national departments, worse in provincial departments and worst in municipalities. The study recommends the establishment of an information governance unit to implement FOI in public bodies. Failure to assign responsibility to a relevant unit would perpetuate the non-compliance with FOI legislation by public bodies in South Africa. A model for the implementation of PAIA within a public body is suggested. 相似文献

Emotional and Behavioral Predictors of Preschool Peer Ratings 总被引:11,自引:0,他引:11

It was predicted that social cognitive, behavioral, and affective aspects of young children's social development would predict stable peer ratings of their likability. Measures of likability, emotion knowledge, prosocial and aggressive behavior, peer competence, and expressed emotions (happy and angry) were obtained for 65 subjects (mean age = 44 months). Sociometric ratings, particularly negative, were stable over 1- and 9-month time periods. Correlational analyses showed that emotion knowledge and prosocial behavior were direct predictors of likability. Prosocial behavior mediated the relations of gender and expressed emotions with likability (i.e., gender and expressed emotions were each related to prosocial behavior, and prosocial behavior was related to likability, but neither gender nor expressed emotions were related to likability with prosocial behavior partialled out). Knowledge of emotional situations similarly mediated the age-likability relation. Results uphold the early development of stable peer reputations and the hypothesized centrality of emotion-related predictors of likability. 相似文献

The MacArthur-Bates Communicative Development Inventories (CDI; Dale, 1996; Fenson et al., 1994), parent reports about language skills, are being used increasingly in studies of theoretical and public health importance. This study (N = 113) correlated scores on the CDI at ages 2 and 3 years with scores at age 3 years on tests of cognition and receptive language and measures from parent-child conversation. Associations indicated reasonable concurrent and predictive validity. The findings suggest that satisfactory vocabulary scores at age 2 are likely to predict normal language skills at age 3, although some children with limited skills at age 3 will have had satisfactory scores at age 2. Many children with poor vocabulary scores at 2 will have normal skills at 3. 相似文献
