“One Day We Had to Run”: The Development of the Refugee Identity in Children’s Literature and its Function in Education

In the last two decades there have been significant numbers of children’s books written about various aspects of the refugee experience. Previously authors had tended to approach this sensitive area principally through an historical perspective. However as the number of refugees in British schools increases, books dealing with contemporary conflicts are published in greater numbers. How do children view this growing body of literature? A short ethnographic study attempts to interrogate the importance of autobiography and personal testimony in the construction of refugee identities in children’s books, and the article discusses the validating role of these texts and their purpose as educative tools in our classrooms. I conclude by considering potential areas within the current curriculum for using story to highlight the situation of those for whom “One day we had to run!”(Wilkes, One Day We Had to Run! London: Evans Bros Ltd., 1994).     

Measuring teachers’ perceptions about differentiated instruction: The DI-Quest instrument and model

Within a democratic and multicultural society, diversity is a reality, and differences between students are a fact which teachers have to deal with on a daily basis. Differentiated instruction aims to meet these differences in learning in order to provide all students with the best possible learning opportunities. However, to date no validated instruments exist to measure teachers’ perceptions of differentiated instruction and their related classroom practices. This study, therefore, examined the factor structure and reliability of the Differentiated Instruction Questionnaire, called the DI-Quest instrument. A list of 87 items was constructed, building on existing prevalent theoretical models of Differentiated Instruction (e.g. Tomlinson, 2014; Hall, 2002). An exploratory and confirmatory factor analysis was undertaken to investigate the factor structure of the questionnaire. As a result, five factors emerged: two factors related to the teachers’ philosophy of differentiated instruction (the teachers’ mindset and their ethical compass), two factors referred to the practical principles that teachers apply to differentiate (flexible grouping and output = input) and the last factor (differentiated instruction) covered the self-reported extent to which teachers differentiated their instruction related to three types of differences in learning (students’ interests, readiness and learning profile). As a result, the DI-Quest instrument entailed 31 items with a five-factor structure indicating a good fit (CFI = 0.919; TLI = 0.911; RMSEA = 0.041 [0.037–0.044 – 90% confidence interval, p(0.05) = 1.000]; SRMR = 0.048; χ² = 5888.338, df = 465, p = 0.000). In addition, assuming theoretical relatedness between the factors, the validation of a DI-Quest model was empirically validated. We compared the model fit for two models by investigating which model had a lower BIC and AIC value and by comparing their chi square values. The best-fitting DI-Quest model showed four factors (teachers’ mindset, ethical compass, flexible grouping and output = input as dependent variables) functioning as significant predictors of the fifth factor (the self-reported adoption of Differentiated Instruction, which served as an independent variable). Moreover, this paper also discusses the psychometric properties of the DI-Quest instrument and the implications of the model for schools, educators and researchers.     

How to understand what you don't believe: Metacognitive training prevents belief-biases in multiple text comprehension

Prior beliefs often bias the comprehension of multiple science-related texts such that belief-consistent texts are better comprehended compared to belief-inconsistent texts (text-belief consistency effect). Two experiments were conducted to investigate whether a metacognitive strategy training focusing on belief-biasing validation processes can reduce the text-belief consistency effect in multiple text comprehension. Participants in the control condition received the PQ4R training as a well-situated and effective reading skill training that increases receptive elaborative processing. In Experiment 1 (n = 39) and Experiment 2 (n = 53) participants receiving a metacognitive strategy training achieved a similar level of comprehension of belief-consistent and belief-inconsistent texts, whereas a text-belief consistency effect was found in the PQ4R condition. These results indicate that a training focusing on belief-biasing validation processes prepare readers for the challenges to comprehend belief-relevant multiple texts, whereas strategies that foster receptive processing of information are not sufficient in the context of controversially discussed topics.

The role of engagement and academic behavioral skills on young students’ academic performance—A validation across four countries

The aim of this study is to validate an instrument measuring students’ academic behavioral skills and engagement—skills identified as vital for student achievement. We inspect the reliability and validity of the survey with respect to item fit, factorial structure, relations with academic performance, and the fairness of the items across student groups. The fairness analyses are critical to making valid comparisons between groups and across countries. Data comprising 8520 grade 10 students from four countries were analysed using item response theory. We found that both scales were multidimensional, acted fairly across students’ gender, country, immigrant-, and socio-economic background (after removing four items), and were positively and significantly correlated with self-reported and performance-based academic performance.     

Development and Validation of an Instrument to Measure University Students’ Biotechnology Attitude

The impact of biotechnologies on peoples’ everyday lives continuously increases. Measuring young peoples’ attitudes toward biotechnologies is therefore very important and its results are useful not only for science curriculum developers and policy makers, but also for producers and distributors of genetically modified products. Despite of substantial number of instruments which focused on measuring student attitudes toward biotechnology, a majority of them were not rigorously validated. This study deals with the development and validation of an attitude questionnaire toward biotechnology. Detailed information on development and validation process of the instrument is provided. Data gathered from 326 university students provided evidence for the validity and reliability of the new instrument which consists of 28 attitude items on a five point likert type scale. It is believed that the instrument will serve as a valuable tool for both instructors and researchers in science education to assess students’ biotechnology attitudes.     

A psychometric approach to the validation of a student evaluation of teaching instrument

The purpose of this study was to conduct a validation analysis of an SET and provide a validation framework of SETs that can be included when designing complete evaluations of teaching within higher education institutions. A series of Rasch analyses was conducted on the results of the SET, examining the responses of students within a college and three departments. Results show the majority of items were moderately difficult to endorse in the college and departments, there were issues with DIF, and two items did not consistently fit the model. The study provides an analysis framework that may aid policymakers and institutional administrators in developing higher quality SETs, and demonstrates the need for validating SETs being implemented in higher education settings.     

Establishing the Criterion-related,Construct, and Content Validities of a Simulation-based Assessment of Inquiry Abilities

The emphasis on scientific inquiry has increased the importance in developing the fundamental abilities to conduct scientific investigations and urged a need for valid assessments of students' inquiry abilities. We took advantage of the advanced technology to develop a simulation-based assessment of inquiry abilities (SAIA) that allowed students to generate scientific explanations and demonstrate their experimental abilities. This paper describes the validation of the assessment. Data were collected from 48 12th-grade students at a local high school who were categorized into three groups based on their program majors. Both quantitative and qualitative approaches were utilized to validate SAIA. The quantitative results showed that SAIA was aligned with a validated reasoning-skill test (criterion-related validity), discriminated variance among different groups (construct validity), and was highly suitable for examining inquiry abilities (content validity). Additionally, we utilized the think-aloud technique in order to identify the performances exhibited by students while they accomplished the SAIA tasks. The protocol analysis indicated that in general, students demonstrated the expected abilities in SAIA and that their SAIA scores accurately reflected their performance levels of inquiry abilities. The results suggested that SAIA was a valid assessment for evaluating the inquiry abilities of high school students. This study also provided systemic strategies for validating simulation-based assessments.     

Development and validation of a reading-related assessment battery in Malay for the purpose of dyslexia assessment

Malay is an alphabetic language with transparent orthography. A Malay reading-related assessment battery which was conceptualised based on the International Dyslexia Association definition of dyslexia was developed and validated for the purpose of dyslexia assessment. The battery consisted of ten tests: Letter Naming, Word Reading, Non-word Reading, Spelling, Passage Reading, Reading Comprehension, Listening Comprehension, Elision, Rapid Letter Naming and Digit Span. Content validity was established by expert judgment. Concurrent validity was obtained using the schools' language tests as criterion. Evidence of predictive and construct validity was obtained through regression analyses and factor analyses. Phonological awareness was the most significant predictor of word-level literacy skills in Malay, with rapid naming making independent secondary contributions. Decoding and listening comprehension made separate contributions to reading comprehension, with decoding as the more prominent predictor. Factor analysis revealed four factors: phonological decoding, phonological naming, comprehension and verbal short-term memory. In conclusion, despite differences in orthography, there are striking similarities in the theoretical constructs of reading-related tasks in Malay and in English.
