ABSTRACTThis study examined upper secondary school students’ citations of self-selected online sources in their essays. Students (n = 140) conducted online inquiry about either effects of social media on people’s quality of life (SM) or allowance of genetic manipulation of organisms (GMO). Students, working either individually or in pairs, explored online sources with the help of a graphic organizer, after which they composed their essays. To capture the quality of citations identified in the essays, they were evaluated in terms of accuracy and richness of source features. Further, regression analysis was used to examine the effect of topic, grade level and work mode on the number and quality of citations. Results showed that students seldom cited sources in their essays, and when they did, citations were mostly accurate but less often rich in source features. When writing about SM, students most frequently cited media sources, while sources with ideological, political or religious motives were frequently cited in GMO essays. Students’ grades and work modes predicted the number of citations and number of accurate citations. 相似文献

Early school leaving is an international concern. Previous research indicates that the school context contributes to early school leaving. This systematic review is aimed to gather marginalised young peoples’ perceptions concerning contextual factors that contributed to and interfered with their decisions to stay in alternative education. Twenty-three databases and reference lists of reviews were searched, eliciting 1586 studies, which were then screened. Data from 24 mixed-methods studies that met the inclusion criteria were extracted and synthesised. Findings suggested that alternative schools which provided a sanctuary for students increased student engagement. Schools were sanctuaries when they offered physical, emotional and psychological safe spaces; fostered a sense of community; enabled students to affirm their racial/ethnic pride and employed flexible behavioural supports. Implications for practice and research are discussed. 相似文献

This paper will consider ways to study educational reform efforts in order to allow policy-making to be developed on a relatively sound basis. At present, educational policy-making often derives from a pastiche of available anecdotes, research-based “good” ideas, and previous administrative guidelines. Educational evaluation efforts should not be used merely to identify and label programs as either “successes” or “failures” at a global level, but rather to permit the analyses of elements or components of programs which seem to be making positive contributions to a common sense perception of program success. A comprehensive, developmental sequence for such evaluation will be described. 相似文献

System competence modelling: Theoretical foundation and empirical validation of a model involving natural,social and human‐environment systems 下载免费PDF全文

Constituting a metacognitive strategy, system competence or systems thinking can only assume its assigned key function as a basic concept for the school subject of geography in Germany after a theoretical and empirical foundation has been established. A measurement instrument is required which is suitable both for supporting students and for the evaluation of methodical‐didactic measures. Such a tool is theoretically anchored in an empirically validated geography‐didactic and cognition‐psychological competence model, providing a differentiated representation of both the internal structure of a competency and the proficiency levels. The starting point of this foundation was the development of a normative‐theoretically derived model of geographic system competence. Its empirical validation was performed in different phases aimed at operationalising the competence model by means of test problems. In order to analyse the factor structure of the theoretical model, various item response models were estimated. The item levels of difficulty expected in the competence model were related to the empirical levels of difficulty and predicted by means of ordinary least squares regression to verify the model for proficiency levels. The two‐dimensional competence model – with the two dimensions ‘system organisation and behaviour’ and ‘system‐adequate intention to act’ – exhibits a better fit in reference to the model fit criteria than the one‐dimensional and three‐dimensional models. The correlations between the expected and empirical item difficulties are positive. Items that should be more difficult according to the competence model are actually shown to be more difficult. These findings suggest the reliability and validity of this new measurement instrument for diagnosing and promoting geographical system competence. It has to be implemented in practice as the next step. 相似文献

In this study we examined whether the underachievement of boys in language at the end of secondary education is related to school‐related attitudes. Data were drawn from the LOSO project, a longitudinal research project in secondary education. The results showed that there were gender differences in language achievement in favour of girls in the lower tracks, but not in the highest track. The underachievement of boys was associated with boys’ less positive relationships with teachers, less positive well‐being at school and less positive attitude towards schoolwork. Furthermore, the results showed that—in the lower tracks—boys who were the least attentive in the classroom, the least interested in learning tasks and the least motivated towards learning tasks achieved better than expected. Post‐hoc analyses revealed that these are the more intelligent boys. Possible explanations of the demotivation of the more intelligent boys in the lower tracks are discussed. 相似文献

This study aimed to investigate parental expectations of early childhood education and care services for young children. A total of 582 parents participated in the research and answered a range of questions relating to their expectations of the social and educational role of early childhood education services in Greece. The findings of the research confirmed that the administrative division between the types of preschool establishments are related with parental expectations for care provision (p < 0.001) and support for their needs (p < 0.05) during their absence from home to work. Also there was strong evidence that parents had high expectations for their collaboration with teachers of early childhood education about (a) solving their personal problems with their child at home (p < 0.001) (b) ensuring the best care provision for their child (p< 0.001) in the early childhood setting and (c) keeping their child happy at the preschool institution with fun activities when they have to go to work (p <0.001). 相似文献

The increasing importance attributed to the cultural dimension of FL education has entailed new demands for teachers and teacher educators. This paper explores the cultural agenda in Finnish language teacher education from a student teacher perspective. The focus is on the students' perceptions regarding how effectively cultural aspects are dealt with in their training, and how these perceptions may be affected by the length of time they have spent abroad. The empirical evidence suggests that both the language studies and the pedagogical studies tend to address cultural aspects to a small or very small extent. The main emphasis is placed on traditional aspects of culture, such as literature and Realia knowledge, and strategies for teaching language seem to overshadow strategies for teaching language and culture in an integrated way. Interestingly, the students' perceptions seem to vary depending on the extent to which they have experienced first‐hand contacts with other cultures. 相似文献

This study was designed to investigate preservice elementary school teachers’ (PSTs’) responses to written standard place-value-operation
tasks (addition and subtraction). Previous research established that PSTs can often perform but not explain algorithms and
provided a four-category framework for PSTs’ conceptions, two correct and two incorrect. Previous findings are replicated
for PSTs toward the end of their college careers, and two conceptions are further analyzed to yield three categories of incorrect
views of regrouped digits: (a) consistently as 1 value (all as 1 or all as 10), (b) consistently within but not across contexts
(i.e., all as 10 in addition but all as 1 in subtraction), and (c) inconsistently (depending on the task). 相似文献

This study presents an analysis of preschool teachers’ reasoning about pedagogical goals. Of specific interest is how teachers in a Swedish and a Finnish context describe goals for children’s learning and how they describe them implementing these goals into their practice. The research question is thus: How are pedagogical goals perceived and enacted, in the thematic-oriented and play-based pedagogical practice of preschool? In-depth interviews were conducted with six preschool teachers, of which three expressed learning goals guiding their pedagogical work. The Variation Theory of learning is the guiding principle throughout the analysis, and reveals indirect and direct objects of learning and content for learning described by the three teachers. A deeper analysis of the features of these provides a comprehensive picture of pedagogical goals that are intertwined and move between activity goals, working goals and transdisciplinary goals. These results contribute to our understanding of the characteristics of preschool pedagogy and the complex pedagogical practice preschool entails. 相似文献
