Assessment reform, in particular a move towards more school‐based forms of assessment, has become a global phenomenon. Involving teachers more centrally in assessment has often been rationalised by claims derived from the literature on formative assessment, hinging on the enhanced validity of performance assessment and the potential of classroom assessment for improving the quality of learning. This paper draws on work in Ghana and England which suggests that in neither case are the potentialities for improvement being realised. Teachers’ conceptualisation of assessment has been a significant barrier to improvement. We present outlines of participatory research projects to address this problem, where practitioners’ own investigation will be used as a way of addressing the need for changes, rooted both in increased technical expertise and in their own belief systems. The divergent contexts for the projects may enable a deeper evaluation of the potential of this methodology than might have occurred in just one country. 相似文献

A practical reinforcement hierarchy was proposed for classroom-based behavior modification programs. The seven-level hierarchy ranged from primitive consequences (Le., Infantile Physical Contact and Food) through the more abstract consequences (i.e., Praise and Internal Self-Reinforcement). Suggestions were made for using the hierarchy in teacher consultation and behavior modification planning. 相似文献

We examined whether young children acquire orthographic knowledge during structured adult-led storybook reading even though minimal viewing time is devoted to print. Sixty-two kindergarten children were read 12 storybook “chapters” while their eye movements were tracked. Results indicated that the children quickly acquired initial mental graphemic representations of target nonwords. This learning occurred even though they focused on the target nonwords approximately one fourth of the total time while viewing the pages. Their ability to acquire the initial orthographic representations of the target nonwords and their viewing time was affected by the linguistic statistical regularities of the words. The results provide evidence of orthographic learning during structured storybook reading and for the use of implicit linguistic statistical regularities for learning new orthographic word forms in the early stages of reading development. 相似文献

ABSTRACT Athlete Biological Passport (ABP) is an indirect approach, implemented by WADA, aimed at detecting blood manipulation based on abnormal changes in haematological markers. Cases report the use of hyperhydration as masking method during anti-doping urine sample collection which could potentially mask suspicious fluctuations on ABP profiles. This study investigated the hyperhydration effect on haemoglobin concentration, reticulocyte percentage and OFF-hr score (an algorithm based on haemoglobin concentration and reticulocyte percentage), with and without recombinant human erythropoietin (rHuEPO) administration. A five-week clinical study performed; Baseline and rHuEPO Phase. Water and a sports drink were used as hyperhydration agents. To examine the hyperhydration effect on the normal ABP profile per volunteer, hyperhydration was implemented at 0, 24 and 48 hours during the baseline. During the rHuEPO phase, volunteers received Epoetin beta (3000 IU) with hyperhydration to be implemented at 0, 24 and 48 hours after drug administration. Blood and urine samples were collected and analysed according to WADA guidelines. No significant effect on ABP markers was observed due to hyperhydration at any time during the study. Pre- and post-hyperhydration data were not statistically different compared to individual baseline data. In conclusion, hyperhydration does not affect the ABP haematological markers under the examined conditions. 相似文献

AbstractThis article presents examples of metadata collaborations between the Swiss National Library (NL) and research institutions in the field of Swiss historiography. The NL publishes the Bibliography on Swiss History (BSH). In order to meet the demands of its research community, the NL has improved the accessibility and interoperability of the BSH database. Moreover, the BSH takes part in metadata projects such as Metagrid, a web service linking different historical databases. Other metadata collaborations with partners in the historical field such as the Law Sources Foundation (LSF) will position the BSH as an indispensable literature hub for publications on Swiss history. 相似文献

Motivated by the observation that formal logic answers questions students have not yet asked, we conducted exploratory teaching experiments with undergraduate students intended to guide their reinvention of truth-functional definitions for basic logical connectives. We intend to reframe the relationship between reasoning and logic by showing how logic emerges within students’ mathematical activity. This activity entails reflecting on and systematizing their own language use across diverse semantic content. We present categories of students’ untrained strategies for assessing the truth-values for mathematical disjunctions. Students’ initial reasoning heavily reflected content-specific and pragmatic factors in ways inconsistent with the norms and conventions of mathematical logic. Despite this, all student groups reinvented the standard truth-functional definition for simple disjunctions. We demonstrate how this learning depended upon particular forms of reasoning about logic. We also contrast various strategies for assessing quantified disjunctions and their different affordances in students’ mathematical activity. 相似文献

This paper presents the results of an analysis of secondary students’ computer use, aimed at understanding how different factors influence the profile of activities carried out by students with computers. The analysis is based on the data from a national study aimed at measuring students’ Information and Communication Technology (ICT) skills for learning. A factor analysis was carried out to categorize students’ activities with computers and several indexes were constructed to define the comparison groups. Finally, a multiple linear regression analysis was performed to explain the frequency of the activities. Results show that students with access to computers at home mainly perform activities categorized as Socializing, Academic, Gaming and Production and that although the absolute frequency of these activities differs across groups, the profiles of computer use are surprisingly similar for groups based on students’ socio-economic group, experience with ICT, and self-confidence in the use of ICT. The only variable that discriminates user profiles is gender. Based on these findings, it can be claimed that Chilean secondary students with access to computers at home tend to show a rather homogenous computer-use profile, once access is equated. 相似文献

Individual differences in solution strategies have frequently been reported for different measures of mental rotation (MR) ability. In the present study (N = 346 German students), we investigated the relationship between solution strategies on two tests commonly used to identify different patterns of strategies: the Mental Rotations Test (MRT; Vandenberg & Kuse, 1978; Peters, Laeng, Lathan, Jackson, Zaiouna, & Richardson, 1995) and the Cube Comparison Test (CCT; Amthauer, 1953; Amthauer, Brocke, Liepmann, & Beauducel, 2001). The results revealed high convergent validity of the solution strategy assignment. Individuals using analytic (holistic) strategies on the MRT tended to use analytic (holistic) strategies also on the CCT. More females than males were identified as users of analytic solution strategies on the MRT. In addition, males tended to generally show a faster performance than did females. Our findings suggest that solution strategies in MR generalize across different tasks and are not an artifact of a particular test. 相似文献

Explicitly considering human values in the design process of socio-technical systems has become a responsibility of designers. It is, however, challenging to design for values because (1) relevant values must be identified and communicated between all stakeholders and designers and (2) stakeholders?? values differ and trade-offs must be made. We focus on the first aspect, which requires elicitation of stakeholders?? situated values, i.e. values relevant to a specific real life context. Available techniques to elicit knowledge and requirements from stakeholders lack in providing the context and means for reflection needed to elicit situated values as well as an explicit concept of value. In this paper we present our design of a tool to support active elicitation of stakeholders?? values and communication between stakeholders and designers. We conducted an exploratory user study in which we compared the suitability of methods used in social sciences for (1) eliciting situated values, (2) supporting people??s expressions of values and (3) being implemented in value elicitation tool. Based on the outcomes we propose a design for a value elicitation tool that consists of a mobile application used by stakeholders for data collection and in-situ self-reflection, and a website used collaboratively by designers and stakeholders to analyse and communicate values. Discussion focuses on contributions to value sensitive design. 相似文献
