The Impact of Model Misspecification on Parameter Estimation and Item‐Fit Assessment in Log‐Linear Diagnostic Classification Models

Using a complex simulation study we investigated parameter recovery, classification accuracy, and performance of two item‐fit statistics for correct and misspecified diagnostic classification models within a log‐linear modeling framework. The basic manipulated test design factors included the number of respondents (1,000 vs. 10,000), attributes (3 vs. 5), and items (25 vs. 50) as well as different attribute correlations (.50 vs. .80) and marginal attribute difficulties (equal vs. different). We investigated misspecifications of interaction effect parameters under correct Q‐matrix specification and two types of Q‐matrix misspecification. While the misspecification of interaction effects had little impact on classification accuracy, invalid Q‐matrix specifications led to notably decreased classification accuracy. Two proposed item‐fit indexes were more strongly sensitive to overspecification of Q‐matrix entries for items than to underspecification. Information‐based fit indexes AIC and BIC were sensitive to both over‐ and underspecification.     

A longitudinal study of handwriting skills in pre-schoolers: the acquisition of syllable oriented programming strategies

Previous studies have shown the relevance of the syllable as a programming unit in handwriting production, both in adults and elementary school children. This longitudinal study focuses on the acquisition of writing skills in a group of preschoolers. It examines how and when the syllable structure of the word starts regulating motor programming in handwriting. Eighteen five year old preschoolers copied six-letter Catalan words (disyllabic and trisyllabic) on a digitiser at three different times over the academic year (January, March, and May). The words were written in uppercase letters. We measured the duration of the inter-letter intervals (ILI) to gather information on the timing of motor programming. The results indicated that from January to March the children were mostly focused on movement proficiency. The results also showed different profiles of ILI duration for the two types of words over the three sessions. For disyllabic words, the syllable regulated movement programming in January; for trisyllabic words, this happened in March. This suggests that the syllable already plays a role in the programming of handwriting movements in kindergarten.     

The pedagogical value of art and music in the past and the present

Pedagogical theory and research practice tend to confine themselves to study the cognitive aspect of a child＇s personality and to focus on his/her productivity, while forgetting about other dimensions. The ability to experience artistic contents and the creative capacity of our society are decreasing. People are in a continuous search for spiritual balance and therefore the task of the contemporary school is to help people get out of this crisis and pay more attention to the realization of educational tasks and goals as well as individual school subjects. Art has always played the role of purposefully influencing the experiencing, feeling, creating and enjoying of beautiful things. It therefore provides a counterbalance to the rationalized world of today. Especially music plays a special role in all periods and all human societies, however, not because it encourages various experiences or notions in the listener or a pleasant atmosphere, but because it presents a challenge to the development of spiritual perception that does not occupy an important, enough place in the present school system. Based on different historical understandings of the pedagogical value of music, the author tries to determine what pedagogical value was ascribed to music in the past and what pedagogical value it is being ascribed today     

Underemployment and employment among young workers and the business cycle in Spain: the importance of education level and specialisation

The objective of this paper is to identify the effect of education on young workers’ time-related underemployment as well as analysing whether education has been a defence mechanism against the recent crisis. Especially relevant is the analysis regarding field of study, which has not been addressed in the underemployment literature. Using data from the Spanish Labour Force Survey 2006–2014, bivariate probit selection models are estimated for three different periods. This methodology enables to analyse the evolution of underemployment among young people, simultaneously considering their probability of employment. The results indicate that underemployment is negatively related to education level for each period and tertiary education has smoothed the negative effect of the recession. Moreover, those specialisations that provide students with specific and work-oriented skills (sciences, technology and health) help workers avoid underemployment and enable them to handle the recession better. Conversely, more generally oriented fields (education, and arts and humanities) are associated with a higher probability of underemployment. Similar patterns have been found regarding unemployment, indicating education plays a similar role in both working time shortages.     

Lexical cohesion and term proximity in document ranking

We demonstrate effective new methods of document ranking based on lexical cohesive relationships between query terms. The proposed methods rely solely on the lexical relationships between original query terms, and do not involve query expansion or relevance feedback. Two types of lexical cohesive relationship information between query terms are used in document ranking: short-distance collocation relationship between query terms, and long-distance relationship, determined by the collocation of query terms with other words. The methods are evaluated on TREC corpora, and show improvements over baseline systems.     

Portfolio practices in higher education in Norway in an international perspective: macro‐, meso‐ and micro‐level influences

The point of departure for this article is the ‘chameleon’ aspect of portfolios and the diversity of portfolio models and practices in higher education on the international arena today. Our aim is to investigate the contextual character of this diversity by using Norwegian higher education as an example and to show how macro‐level influences, particularly the Bologna related Quality Reform, have shaped the overall development of portfolio practices. We contextualise and discuss the sudden expansion of learning and assessment portfolios in Norway after 2002. Our data are primarily a nationwide survey of portfolio practices, supplemented by findings in a research evaluation of the reform and previously published case studies. The majority of portfolios in Norwegian higher education can be classified as ‘disciplinary‐based course work portfolios’ and they typically serve a combination of learning and assessment purposes. But within this category we found systematic differences between different educational areas where the main dividing line seems to be between professional and non‐professional education. The underlying research perspective is sociocultural and this directs our attention to contexts, cultures and traditions that shape portfolio development and practices rather than to individual differences (micro level).     

The role of family literacy classes in demystifying school literacies and developing closer parent–school relations

This paper is based on a large study of family literacy provision in England, which was carried out between July 2013 and May 2015. It explored the impact of classes on parents’ relations with the school and their children, and their ability to support their children’s literacy development. The study involved 27 school-based programmes for pupils aged between five and seven, and their parents. It used mixed methods, which involved surveys of 118 parents and 20 family literacy tutors, telephone interviews with a sub-sample of 28 parents, analysis of teaching plans and observations of classes. Findings showed that parents wanted to learn the ways the school was teaching their child to read and write, and by demystifying school literacy pedagogies and processes the programmes developed greater connectivity between home and the school, and parents felt more able to support their children’s literacy development at home.     

The impact of theories of 'New Public Management' on the provision of support services for low-incidence special needs

This short report examines the impact of changes of government policy within England and Wales on the organization and provision of support services to pupils with a low-incidence disability. The specific case of support for pupils who are visually impaired is explored against a framework based on theories of ‘New Public Management’.
