Inquiry-based lessons have been demonstrated to improve children’s scientific thinking (i.e. reasoning abilities and domain-specific knowledge). Although empirical evidence shows that inquiry-based learning requires instruction, research comes from two approaches that have not been bridged yet: direct instruction of scientific reasoning and teacher training of verbal support. We investigated how these two types of instruction separately or combined strengthened children’s scientific thinking by comparing four conditions: baseline, direct instruction, verbal support, and a combined approach. Effectiveness of an inquiry-based lesson series on scientific reasoning abilities, vocabulary, and domain-specific knowledge (near and far transfer) were studied among 301 fourth graders. Results showed that both approaches strengthened different components of scientific reasoning abilities, and that a combination of instructions was most effective for scientific reasoning abilities, vocabulary, and domain-specific knowledge. Domain-specific knowledge acquisition was strengthened only when both instructions were provided. It can thus be concluded that each type of instruction has unique contributions to children’s science learning and that these instructions complement each other. Our study thus showed that inquiry-based lesson series when preceded by direct instruction of scientific reasoning and scaffolded with verbal support are most effective. 相似文献

Socio‐economic background,parental involvement and teacher perceptions of these in relation to pupil achievement 总被引：1，自引：0，他引：1
Parental involvement and teacher perceptions of parental involvement in the education of children were studied in relation to level of parental education and pupil achievement. A questionnaire was administered to 218 parents and 60 teachers. Correlational analyses and paired‐sample analyses showed teacher perceptions to be weakly related to parental reports of their own involvement and to operate at a different level. Regression analyses and analyses of variance showed teacher perceptions of parental involvement to affect pupil achievement more strongly than parental reports. The results suggest that teacher perceptions of parents may be stereotyped and that such stereotypes can clearly affect academic results. 相似文献

Abstract In Vietnam, agricultural extension has contributed to rural development and poverty alleviation over the past two decades of agricultural decollectivization, but it was not very effective in reducing disparities within farmer communities. The study examined how better interactions of extension services with other agencies and information sources may help marginal farmers in catching up with the general improvement of living conditions in a mountainous area in northern Vietnam. It combined three complementary viewpoints on this issue: that of the agricultural extension staff, that of farmers and that of development experts with a long working experience in the mountains of Vietnam. The analysis of existing structures and functions of the extension system revealed a number of obstacles to the participation of marginal farmers in extension programmes and helped to identify relevant domains of intervention. 相似文献

This study was designed to investigate the trust relationship between parents and teachers in first grade. Additional research questions were whether trust was related to ethnicity and reading performance. The five facets of trust; benevolence, reliability, competence, honesty and openness, were measured on a 4-point Likert scale. Reading performance was measured by the three-minute test. Parents were found to have more trust in the reliability, competence and honesty of teachers than teachers in parents. Native-Dutch and immigrant parents have the same trust level towards their children’s teacher. However, teachers reported lower trust levels on all five facets of trust for immigrant parents. Our findings indicated that ethnicity has no influence on parents trust in teachers, but ethnicity may explain teachers’ trust in parents. Some support was found for the assumption that teachers’ trust plays a role in reading performance. Children were found to have higher reading performance when teachers reported higher trust in the benevolence and openness of parents. 相似文献
