We investigated relationships among elementary teachers’ reading-related content knowledge (knowledge of literature and phonology), their philosophical orientation toward reading instruction, their classroom practice, and their students’ learning. Correlations showed little relationship between instructional philosophy and content knowledge, and little relationship between instructional philosophy and classroom practice. However, relationships emerged between content knowledge and instruction, and between kindergarten teachers’ phonological knowledge and their students’ reading achievement. We recommend that the recent focus on teacher’s disciplinary knowledge be broadened to include teachers of beginning reading and that teachers be afforded opportunities to develop the necessary knowledge base to teach reading effectively.  相似文献

As part of the American Recovery and Reinvestment Act of 2009, the School Improvement Grants (SIG) program received more than $3 billion with the goal of substantially improving student achievement. The SIG program’s funding was to help states turn around the nation’s persistently lowest-achieving schools using one of four school intervention models—transformation, turnaround, restart, or closure. We used a regression discontinuity design and a large sample of schools from more than 20 states to evaluate the impact of implementing a SIG-funded intervention model on use of SIG-promoted practices and student outcomes. Our regression discontinuity design exploited cutoff values on the continuous variables used to define the SIG eligibility tiers to compare outcomes in schools that just met the eligibility cutoff for receiving SIG funding to outcomes in schools that just missed it. We found that SIG had no impact on any of the outcomes we examined, including math and reading test scores, high school graduation rates, and college enrollment rates. Using a correlational analysis, we found the turnaround model was associated with larger student achievement gains in math than the transformation model for grades 6 through 12.  相似文献

A user’s single session with a Web search engine or information retrieval (IR) system may consist of seeking information on single or multiple topics, and switch between tasks or multitasking information behavior. Most Web search sessions consist of two queries of approximately two words. However, some Web search sessions consist of three or more queries. We present findings from two studies. First, a study of two-query search sessions on the AltaVista Web search engine, and second, a study of three or more query search sessions on the AltaVista Web search engine. We examine the degree of multitasking search and information task switching during these two sets of AltaVista Web search sessions. A sample of two-query and three or more query sessions were filtered from AltaVista transaction logs from 2002 and qualitatively analyzed. Sessions ranged in duration from less than a minute to a few hours. Findings include: (1) 81% of two-query sessions included multiple topics, (2) 91.3% of three or more query sessions included multiple topics, (3) there are a broad variety of topics in multitasking search sessions, and (4) three or more query sessions sometimes contained frequent topic changes. Multitasking is found to be a growing element in Web searching. This paper proposes an approach to interactive information retrieval (IR) contextually within a multitasking framework. The implications of our findings for Web design and further research are discussed.  相似文献

The increasing number of second language learners in classrooms all around the world has required teachers to adapt their teaching methods and materials to the various learners’ needs. Second language learners in particular need specific learning strategies, which not only aim at helping them understand the linguistic structure of the language of instruction, but also enable them to remember and comprehend the many different words in this “foreign” language. For second language learners, developing reading skills and improving language abilities need to go hand in hand independent of the language. This article presents suggestions for reading lessons emphasizing vocabulary for both first and second language learners of various linguistic backgrounds. These suggestions are especially useful for reading lessons in mainstream second and third grade classrooms. Approaches to vocabulary building are discussed with particular focus on aspects to be considered for vocabulary selection (e.g. linguistic aspects); followed by recommendations on the instruction of the selected vocabulary. All the presented suggestions are based on materials developed in the context of a project in Austria, hence in a German speaking environment. Applicability of these suggestions for other languages is emphasized.  相似文献

According to the design principle of progressive schematization, learning trajectories towards procedural rules can be organized as independent discoveries when the learning arrangement invites the students first to develop models for mathematical concepts and model-based informal strategies; then to explore the strategies and to discover pattern for progressively developing procedural rules. This article contributes to the theoretical and empirical foundation of the design principle of progressive schematization by empirically investigating students’ individual schematization pathways on the micro-level for the specific case of part-of-part determination of fractions. In design experiments series in laboratory settings, nine pairs of sixth graders explored the part-of-part determination and progressively schematized their graphical strategies before discovering the procedural rule. The qualitative in-depth analysis of 760 min of video shows that progressive schematization is a multi-facetted process that cannot be described by internalization of graphical procedures alone. Instead, the compaction of concepts- and theorems-in-action is crucial, especially for the goal of justifiable procedural rules.  相似文献

In contrast to other career choices, the teaching profession seems familiar to those interested in teaching because they have had the chance to observe teachers for years. This phenomenon is known as the apprenticeship of observation and manifests in naïve ideas and expectations of teaching among teacher students. Therefore, characteristics of students interested in becoming teachers are important for early teacher education and counselling. These characteristics include competencies and motives, but nothing is known about their relationship to each other. Following international teaching standards and the expectancy-value framework, this paper analyses associations between both. Three competencies (i.e. planning, communication and cooperation) and seven career choice motives were examined using a paper–pencil survey of 907 high school students. Altogether, 463 students were able to imagine becoming a teacher and were included in the analyses. SEM analyses showed that (1) of all the competencies, communication had the most associations with motives, (2) the motive ‘low difficulty of study’ is positively related to planning, (3) the findings regarding extrinsic motives are ambiguous, and (4) gender differences are marginal. Practical implications for early teacher education and counselling are discussed.  相似文献

Higher education institutions increasingly recognise the need to develop both disciplinary knowledge and soft skills to foster the employability of their graduates. For students in International Studies programmes, the workplace opportunities to develop soft skills relevant to their intended professions are scarce, costly and unavailable to many. This paper argues that universities can harness the power of ICTs in ways that students find engaging and offer opportunities to gain professional experience that prepares them for an international workplace. We describe a new work-integrated learning model that embeds a multi-layered in-person simulation within an academic context. Facilitated by cross-national pedagogical collaboration, students participate live in cross-campus experiential learning with online peers. Students’ reflections on the model indicate that this model can foster a range of generic soft skills that enable them to apply their academic knowledge, collaborate with a culturally diverse group and work in a digital world. To refine this blended learning model, more attention needs to be paid to designing appropriate evaluation tools and harnessing cultural diversity more effectively.  相似文献
