ABSTRACTBased on concerns about the item response theory (IRT) linking approach used in the Programme for International Student Assessment (PISA) until 2012 as well as the desire to include new, more complex, interactive items with the introduction of computer-based assessments, alternative IRT linking methods were implemented in the 2015 PISA round. The new linking method represents a concurrent calibration using all available data, enabling us to find item parameters that maximize fit across all groups and allowing us to investigate measurement invariance across groups. Apart from the Rasch model that historically has been used in PISA operational analyses, we compared our method against more general IRT models that can incorporate item-by-country interactions. The results suggest that our proposed method holds promise not only to provide a strong linkage across countries and cycles but also to serve as a tool for investigating measurement invariance. 相似文献

This report describes a study which explores, from the out-of-school student viewpoint, why students are not studying chemistry anymore. In a 2-day stay at a research institution three groups of graduating high school students from different schools, together with their chemistry teacher, were confronted hands-on with molecular modeling in industry and in university. Each of these volunteer students had agreed to write an essay on School Chemistry Vs. Chemistry in Research. These essays were evaluated together by the students, the teacher, and the researcher in a meeting at their school. The opinion of the students show that school chemistry does not convey today's chemistry in research and in industry. At the computer screen the students demonstrated their skill in performing molecular modeling experiments. Moreover, at the computer screen, chemistry was fun and easier to understand. Now we begin to see the solution: our students are also our teachers. 相似文献

AbstractThis paper focuses on understanding and exploring how a group of university engineering and science tutor educators learn and assimilate new conceptions about their role in the face of the forces of globalisation that are transforming the system of higher education. This research paper adopts the notion of the Teacher Support Team (TST) as developed by Daniels and grounded in Vygotsky’s sociocultural account of the social formation of mind. These structures of meaning provide insight into the role played by the context, the interactions, the needs and the demands of actual activities, agreements and learning processes that this group of STEM lecturers undertook as they sought to transform their usual teaching methods that were focused on individual and isolated work in order to create more innovative practices and impact on their students’ performance. The analysis of this experience, which was based on the epistemological principles of the sociocultural approach, focused on the educational model that emerges from needs that are perceived and shared through the group’s interactions, as well as the transitions that such a team undergoes in its actions and decisions. 相似文献

We report on two studies in which high school students who had been exposed to a cognitive training procedure known as the Conceptual Mediation Program (CMP) were compared to students who had not participated within the program. In the first study, based on data from two sites, it was found that 70 CMP students exhibited higher levels of school affect and strategy awareness than 103 comparable students not in the program. In the second study, based on retrospective data from one site, 53 students who had participated within CMP classes were found to exhibit higher levels of attainment on Year 12 South Australian public examination results (effect size of 1.04 on the aggregate). On the Year 12 examination results, the CMP students outperformed both the school and state norms. 相似文献

Some students in the upper elementary grades and high schools may benefit from extended decoding and spelling instruction. These students, because of their age level and reading selections, require strategies going well beyond phonics. For these older readers, including adults, learning about morphological structure may provide the strategies needed to decode and spell multisyllabic words found often in literature and content area texts. In this paper, literature providing a rationale for such instruction is reviewed, and a curriculum and instructional plan is described. 相似文献
