This paper describes a study of “Word Score”, a serious game designed to extend the vocabulary of pupils in upper primary school in the Netherlands. Word Score was used in one school community as part of the national project “Educational Time Extension” (ETE). In ETE class time is extended beyond normal school hours with the aim of improving the learning outcomes of under-performing pupils. The study showed that the use of Word Score can be effective during ETE. The vocabulary of the pupils who played the game outside the regular class time significantly increased. The experiences of both pupils and teachers were very positive. The pupils liked playing Word Score and the teachers were very enthusiastic about the game and the pupils’ results. 相似文献

The majority of studies examining the language and literacy skills of second generation immigrant bilingual children have focused on the breadth of lexical knowledge in populations with a low level of involvement in literacy activities. This study extends previous work in three ways. First, we focused on a sample of second generation immigrant bilingual children from favorable socio-cultural backgrounds. Second, we examined whether these children show lexical knowledge gaps in their second language on various measures of breadth and depth, as compared to their monolingual peers. Finally, we asked whether this gap tends to increase, remain stable, or decrease with formal schooling. Bilingual (n?=?70) and monolingual (n?=?55) children between the ages of 7 and 8?years were evaluated on measures of depth and breadth of lexical knowledge in the second language of the bilingual group. Both groups were tested twice: at the beginning of second grade and at the beginning of third grade. The findings indicate a significant gap between the target groups with respect to most measures of both depth and breadth at the beginning of second grade. However, after a year of schooling, the bilingual children showed significant progress in their lexical knowledge in their second language. The discussion addresses theoretical and clinical implications of these findings. 相似文献

This paper addresses the development in children’s and adults’ awareness of the benefits of writing through the analysis of change in notetaking while engaged in scientific inquiry over 10 weeks. Participants were given a notebook that they could choose to use. Our results indicate consistent differences between the performance of adults versus children and also across time. First, there were clear differences in the number of participants who chose to take notes. Second, not only did adults write more notes than children, but also the adults’ mean number of notes slightly increased over time, whereas children’s notes actually decreased in frequency. Third, children and adults differed in the types of notes they took. These results are interpreted in terms of participants’ awareness of what needs to be noted in a scientific task and why it needs to be noted, and they suggest implications for educational practice. First, because learners often have inaccurate representations of the task demands and their own future state of knowledge, they do not perceive the utility of notetaking. Second, because of these misperceptions, learners do not refer back to their notes and thereby miss feedback that would spur the refinement of their metacognitive (particularly metastrategic) knowledge and strategy use. Educators need to design opportunities for students to engage in activities that increase metacognitive knowledge of their own cognitive abilities and the demands of the task. 相似文献

The present study examines the mutual interaction between students' writing and scientific reasoning among sixth‐grade students (age 11–12 years) engaged in scientific inquiry. The experimental task was designed to promote spontaneous record keeping compared to previous task designs by increasing the saliency of task requirements, with the design goal of making the relationship between record keeping and inquiry strategies more explicit and visible. Compared to previous studies, this new task design resulted both in a higher amount of record keeping overall and in a higher quality of information, which is interpreted to be a result of increased participants’ metatask and metastrategic knowledge arising from greater engagement with the task. The study found a significant relationship between the quality of students' record keeping and the inquiry strategies that were investigated. However, this relationship varied depending on the type of inquiry strategy. Strategies that are employed during the design of experiments (i.e., factorial combination strategy and control‐of‐variables strategy [CVS]) were statistically related to the number of complete comments (plans and intents), but not with the total number of comments. In contrast, the study found that for strategies employed while evaluating evidence (i.e., drawing inferences), student production of quality records is a necessary but not sufficient condition for effective evidence evaluation; in addition to recording high‐quality information, students must also review their records (both from design and evaluation phases). 相似文献

Research in science education has documented achievement gaps between men and women in math and physics that may reflect, in part, a response to perceived stereotype threat. Research efforts to reduce achievement gaps by mediating the impact of stereotype threat have found success with a short values-affirmation writing exercise. In biology and biochemistry, however, little attention has been paid to the performance of women in comparison with men or perceptions of stereotype threat, despite documentation of leaky pipelines into professional and academic careers. We used methodologies developed in physics education research and cognitive psychology to 1) investigate and compare the performance of women and men across three introductory science sequences (biology, biochemistry, physics), 2) document endorsement of stereotype threat in these science courses, and 3) investigate the utility of a values-affirmation writing task in reducing achievement gaps. In our study, analysis of final grades and normalized learning gains on content-specific concept inventories reveals no achievement gap in the courses sampled, little stereotype threat endorsement, and no impact of the values-affirmation writing task on student performance. These results underscore the context-dependent nature of achievement gaps and stereotype threat and highlight calls to replicate education research across a range of student populations. 相似文献

The aim of this exploratory study was to examine the role of the First Language First model for preschool bilingual education in the development of vocabulary depth. The languages studied were Russian (L1) and Hebrew (L2) among bilingual children aged 4–5 years in Israel. According to this model, the children’s first language of educational instruction (up to age three) is the language to which they are exposed at home. Their second language—the dominant language of the country that is spoken by the majority of the population—is acquired sequentially, after relative maturity in the first language. Fifty-one Russian/Hebrew-speaking bilinguals (around age four) were selected from bilingual (Russian/Hebrew) preschools, which used the First Language First approach, and monolingual (Hebrew) preschools. The research was designed as a longitudinal study, as the children’s vocabulary was measured at two time-points—near the beginning and the end of the academic year. The children’s vocabulary was measured in both languages by examining its depth dimensions (paradigmatic semantic relations and syntagmatic semantic relations). The results demonstrated that the later immersion in L2 and continuing development of L1 within the First Language First model does not results in retardation in development of bilingual children in L2 in comparison to their bilingual peers from the monolingual (Hebrew) preschools. In addition, this model of early bilingual development enhances the linguistic interdependence of depth of vocabulary knowledge, and, therefore, supports balanced bilingual development. 相似文献

The aim of this study was to identify the specific contribution of executive functions to pre-academic skills (emergent literacy, phonological awareness and orthographic knowledge, and emergent mathematic knowledge) over and above cognitive and linguistic underpinning abilities such as naming, short-term memory and vocabulary. The study was designed to examine the following questions: (1) Are executive functions related to pre-academics skills in general or are they related to specific pre-academic skills? (2) Does the magnitude of the relationship between executive functions and pre-academics skills change with the progress in pre-school age? 54 children between the ages of 5 and 6 years old from 4 different kindergartens participated in the project. A wide range of pre-academic skills, cognitive, linguistic and executive functions tasks were administered. The results demonstrated that executive functions contributed significantly to both emergent literacy and emergent mathematic knowledge. In addition, the current study also suggests that the role of executive functions increases with the growth of child’s pre-academic development. Finally, the strongest contribution of executive functions was found to orthographic knowledge. 相似文献
