Effects of a rubric for mathematical reasoning on teaching and learning in primary school

Rubrics are assessment tools that help students gain complex competencies. Our quasi-experimental study aimed to evaluate whether rubrics help teachers teach and assess mathematical reasoning in primary school and whether such an instrument might support student learning. In two Swiss cantons, 762 students in 44 5th- and 6th-grade primary classes worked on their reasoning competencies, and half of them additionally employed our standards-based rubric. All of the teachers received a 1-day training and participated in the final project evaluation. To standardise and support the teachers during the implementation phase, they received a detailed curriculum. An achievement test and questionnaires for students and teachers were administered before and at the end of the intervention. The results of our quantitative longitudinal analyses indicate that the rubric fosters the teachers’ perceived diagnostic skills but only indirectly impacts their use of formative feedback. Based on the students’ perceptions, however, we observed a direct effect of the rubric on formative feedback and student self-assessment. Effects on students’ outcomes could not be observed, but there are indications of effects mediated by self-regulation and self-efficacy.  相似文献

Who gets access to fast broadband? Evidence from Los Angeles County     

Hernan Galperin  Thai V. Le  Kurt Wyatt 《Government Information Quarterly》2021,38(3):101594

Regulatory and market changes in residential (fixed) broadband have raised concerns about Internet Service Providers (ISPs) prioritizing investments in the most profitable areas, thus relegating low-income and minority communities to fewer broadband options and legacy networks. This study examines these concerns for Los Angeles (LA) County during the 2014–18 period. The analysis uses rollout data collected by the California Public Utilities Commission (CPUC) in combination with demographic information from the American Community Survey (ACS). Because the spatial distribution of broadband investments cannot be directly observed, competition and the availability of FTTH services are used as proxies. The findings indicate that competition and fiber-based services are less likely in low-income areas and minority communities, with the most severe deficits observed in census block groups that combine poverty and a large share of Black residents. We outline alternative policy tools to address intracity inequalities in broadband investments in the conclusion.  相似文献   

Creating technology-enriched classrooms: implementational challenges in Turkish education     

Serhat Kurt 《Learning, Media and Technology》2014,39(1):90-106

This paper provides an overview of the status of educational technology in Turkey. In the face of severe social and economic challenges, many developing nations, including Turkey, are looking to education as a potential remedy. Recognizing that in an increasingly technology-dependent world, information and communications technology skills and knowledge are critical in order to compete in the global marketplace, Turkey is firmly committed not only to improving its education system, but also to incorporating the use of educational technologies into the instructional strategy and curriculum used in schools. This is a critical initiative because, as research shows, technology-enriched educational environments can provide students with significantly expanded learning opportunities, which are linked with increased levels of academic achievement. However, like many other developing countries, Turkey is struggling to overcome a number of serious barriers to full technology integration at the classroom level, the most significant of which is non-compliance on the part of teachers. With respect to technology use in education, teachers are consistently failing to utilize technological tools for instruction purposes, for a variety of reasons. Turkey must address these reasons in order to ensure that the agenda of technology adoption into schools, an enormously expensive undertaking, does not fail.  相似文献

Teaching for understanding and/or self-regulated learning? A video-based analysis of reform-oriented mathematics instruction in Switzerland     

Christine Pauli  Kurt ReusserUrs Grob 《International Journal of Educational Research》2007,46(5):294-305

In mathematics instruction, can a teacher implement surface features of instruction that foster self-regulated learning as well as achieve quality at the deeper level of instruction, that is, focus on higher-order thinking, problem-solving, and mathematical modeling? An educational reform effort in Switzerland, which is based on constructivist and sociocultural theories of mathematics learning, targets both these dimensions: self-regulated learning and conceptual understanding. We examined the realization of the two dimensions in classroom instruction in a video-based study of 79 eighth-grade math classes using three kinds of data: videotapes of mathematics lessons, student and teacher questionnaires, and achievement tests. As to the surface level of instruction, teachers reported how frequently they provided opportunities for self-regulated learning. With regard to the deeper level of instruction, teachers reported how frequently they provided opportunities for independent problem solving. In addition, we examined the extent to which teachers’ pedagogical beliefs reflected a constructivist orientation. The results showed that teachers implemented the two dimensions relatively independently of one another. Teachers’ constructivist-oriented beliefs influenced only opportunities provided for independent problem solving and did not affect opportunities for self-regulated learning. Opportunities for self-regulated learning had a positive effect on students’ learning experience. Professional development should encourage teachers to take greater account of both surface-level and deeper-level (quality) features of instruction.  相似文献   

Mobile Agents for Distributed and Heterogeneous Information Retrieval   总被引：1，自引：0，他引：1

The heterogeneous, distributed and voluminous nature of many government and corporate data sources impose severe constraints on meeting the diverse requirements of users who analyze the data. Additionally, communication bandwidth limitations, time constraints, and multiple data formats impose further restrictions on users of these distributed data sources. In this paper, we present an Agent-based Complex QUerying and Information Retrieval Engine (ACQUIRE) for large, heterogeneous, and distributed data sources. ACQUIRE acts as a softbot or interface agent by presenting users with a view of a single, unified, homogenous data source, against which users can pose high-level declarative queries. ACQUIRE translates each such user query into a set of sub-queries by employing a combination of planning and traditional database query optimization techniques. ACQUIRE then spawns a set of mobile agents corresponding to these sub-queries, which in turn retrieve the data from various distributed data sources by dynamically optimizing the retrieval strategy as it is carried out. These mobile agents carry with them data-processing code that can be executed at the remote site, thus reducing the size of data returned by the agent. When all mobile agents have returned, ACQUIRE filters and merges the retrieved data and presents the results to the user. While the system is still very much a work in progress, current validation experiments on simulated NASA Distributed Active Archive Centers (DAACs) have demonstrated that complex queries can be effectively decomposed and retrieved by this approach.  相似文献
