Evaluating item response theory linking and model fit for data from PISA 2000–2012

ABSTRACT

Based 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.     

School Chemistry vs. Chemistry in Research: An Exploratory Experiment

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.     

The social construction of a Teacher Support Team: an experience of university lecturers’ professional development in STEM

Abstract

This 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.     

Morphological structure: Latin and Greek roots and affixes as upper grade code strategies

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.     

Teacher Support Teams for Special Educational Needs in Primary Schools: evaluating a teacher-focused support scheme

This paper reports on part of an evaluation of teacher support teams (TSTs) as a special education needs (SEN) support strategy in primary schools. Using a mixture of quantitative and qualitative evaluation methods, it focuses on areas derived from a theoretical framework for understanding schools’ approaches to SENs. TSTs were set up and run in six of the eight schools, with meetings of between 30 and 45 minutes, usually during lunchtime or after school. Most of the referrals were about behaviour problems, though many were about learning difficulties. The support included providing emotional encouragement, specific approaches to managing behaviour, teaching strategies and consulting others. Referring teachers reported that their TST experience led to increased confidence and some improvements in the children, while TST members themselves believed that they had gained much from the TST experience. Overall the study showed the feasibility and benefits of setting up TSTs in primary schools. The findings are discussed in terms of the wider benefits of TSTs and their relevance to special needs policies and the implementation of the SENs code of practice.     

A Review of Get Out: On White Terror and the Black Body

This essay provides a review of Jordan Peele's film, Get Out. The author argues that Peele's Get Out illustrates the protracted terrorism that is whiteness and the concomitant objectification and utilization of the black body for white survival, accumulation, and pleasure. The film challenges those in education to consider how anti-blackness operates within schools and education policy. More specifically, those in education should challenge longstanding inequities that foreclose the presents and futures of black youth.
