Instrument adaptation in cross-cultural studies of students’ mathematics-related beliefs: learning from healthcare research

Much comparative research into education-related beliefs has exploited questionnaires developed in one culture for use in another. This has been particularly the case in mathematics education, the focus of this paper. In so doing, researchers have tended to assume that translation alone is sufficient to warrant a reliable and valid instrument for cross-cultural research, prompting concerns that a number of necessary equivalences are unlikely to have been addressed. In this paper, we consider the nature of these equivalences before examining the literature of a different field, healthcare research, to synthesise an approach to instrument adaptation that is pragmatic but rigorous. Finally, we demonstrate how this pragmatic approach, incorporating extensive cognitive interviews, enabled us to adapt and refine a mathematics-related beliefs questionnaire, developed in Flanders, for use with students aged 14–15 in England and Spain. Analyses indicate that the instrument so developed is multidimensional, reliable and cross-culturally valid. Some implications are discussed.     

Gender differences in adolescents’ choice of heroes and admired adults in five countries

Seven hundred and sixty-eight adolescents from five countries and regions (USA, Spain, Hong Kong, Qatar, and Malaysia), aged 13–19 (M?=?15.78; SD?=?1.28) years, responded to a questionnaire designed to determine who was their most admired famous adult or hero. Male heroes clearly outnumbered admired females (73.3% vs. 26.7%). There was a pattern of same-sex choices, but it was more likely for girls to choose male heroes than for boys to choose females. Over half of the admired adults were athletes, and movie, television, and music stars. Regarding the personally known adults, there was a more balanced choice of males and females, with parents as the most frequent choice. Results suggest that society continues to fail in providing an adequate supply of female role models.     

A Review on the Role of Nutraceuticals as Simple as Se2+ to Complex Organic Molecules Such as Glycyrrhizin That Prevent as Well as Cure Diseases

Nutraceuticals are nutritional medicines which are present in edible food items. Most of them are antioxidants with various other biological properties viz, anti inflammatory, anti atherogenic, anticancer, anti viral, anti aging properties etc. They are as simple as minerals like Se²⁺ to complex organic molecules such as glycyrrhizin (Ca²⁺, K⁺ salts of glycyrrhizic acid). They can prevent as well as cure various diseases. Most of the medical people are not aware of the importance of the nutraceuticals as such matters are not part of their text books. Many still think that vitamins are the major nutritional medicines. Actually other dietary principles like terpenes, carotenes, phytosterols, polyphenols, flavanoids, di and poly sulphides, their sulfoxides and their precursor amino acids are necessary to scavenge free radicals in the body which are reactive oxygen species to protect and maintain the vitamin levels in the body. They down regulate the activities of those enzymes which are increased in diseases and they increase those that remove oxidants and detoxify carcinogens. They are immune boosters too. Recently glucosinolates, non toxic alkaloids, certain proteins and even fiber are included in the list of nutraceuticals.     

How do your rivals’ releasing dates affect your box office?

In this paper, we study to what extent a movie’s box-office receipts are affected by the temporal distribution of rival films. We propose a reduced-form empirical model to measure and test competition effects among films released close to each other in a standard regression framework. Such an analysis is appealing in terms of its policy implication and may provide guidance to distributors to decide on their releasing dates of their firms. We estimate this model using information on the films released in five countries: the USA, the United Kingdom, Germany, France and Spain. The geographical dimension of our data set permits us to control for unobserved heterogeneity among films released using panel data techniques, which allows us to evaluate the individual and specific effects of each film. Thus we deal with one of the most relevant features of the movie market, namely the presence of highly differentiated products.     

Application of Think Aloud Protocols for Examining and Confirming Sources of Differential Item Functioning Identified by Expert Reviews

This paper demonstrates and discusses the use of think aloud protocols (TAPs) as an approach for examining and confirming sources of differential item functioning (DIF). The TAPs are used to investigate to what extent surface characteristics of the items that are identified by expert reviews as sources of DIF are supported by empirical evidence from examinee thinking processes in the English and French versions of a Canadian national assessment. In this research, the TAPs confirmed sources of DIF identified by expert reviews for 10 out of 20 DIF items. The moderate agreement between TAPs and expert reviews indicates that evidence from expert reviews cannot be considered sufficient in deciding whether DIF items are biased and such judgments need to include evidence from examinee thinking processes.     

‘We are more than EFL teachers – we are educators’: emancipating EFL student-teachers through photovoice

The prevailing pedagogical orientations of English as a foreign language (EFL) education in Spain oppress learners intellectually in ways that are counterproductive to their learning. As a reaction to this, 129 EFL student-teachers (STs) took part during the 2013/14, 2014/15, and 2015/16 academic years in a workshop which drew on the methodology of participatory action research and on photovoice as a data-creating strategy, in order to emancipate these STs intellectually, boost their EFL development, and offer an alternative critical model for their future EFL teaching. The research was assessed collectively through a variety of qualitative strategies. Results showed that the photovoice workshop created a rich and meaningful context for EFL learning, one which enabled the STs to fully actualize their intellectual potential by producing knowledge collectively, thereby setting a memorable educational example for their own future teaching.     

Renewed commitments in a time of vigilance: sexuality education in the USA*

Over the past 20 years, the USA has seen more than its fair share of controversy with respect to education about sexuality, sex and intimate relationships. Attention has focused on content (abstinence-only vs. comprehensive instruction), delivery (by teachers, parents, health professionals or community educators) and context (within school and beyond). In recognition of this fact, Sex Education invited the development of a virtual special issue comprising a sample of its most impactful papers on these and related topics. The 2016 Presidential election results and recent legislative action in the USA point to the importance of thinking broadly about teaching and learning about sexuality inside and outside of schools and of considering sexuality as it intersects with categories of difference, privilege and penalty, including ability, age, immigration, race, gender and class. This paper, developed as an introduction to the virtual special issue, opens with a discussion of the journal’s contributions to the ongoing discussion of pleasure and desire in sexuality education. From there, we turn to the question of what is possible given the material and ideological conditions of schooling and then to opportunities for teachers and learners outside the conventional classroom. We follow with a discussion of the place of intersectional analyses in sexuality education research, and conclude with some thoughts on sexuality education research at this political moment.
