Assessing the Nature of Science: What is the Nature of Our Assessments?

This paper discusses the nature of the instruments used to assess students' and teachers' conceptions of the nature of science during the last four decades. Two salient points emerge from critically reviewing the various research emphases and associated assessment instruments specifically related to the nature of science. The first is to question the validity of much of the research presented on the grounds that (a) assessment instruments are interpreted in a biased manner, and (b) some assessment instruments appear to be poorly constructed. Although such comments are well founded, it is important to note that the research conclusions were unusually uniform regardless of the particular instrument used in an investigation. The second point is a more critical concern about the traditional paper and pencil approach to the assessment of an individual's understanding of the nature of science. Although not a new insight, discrepancies between the interpretation of a written response to a traditional instrument (e.g., multiple choice assessment) and the intent of the respondent have been well documented. It is suggested that the current educational research shift toward more qualitative, open-ended approaches to assessment of individuals' understanding (of any concept) be applied to the assessment of individuals' nature of science conceptions.     

Young people’s views on sexting education and support needs: findings and recommendations from a UK-based study

Young people’s sexting is an area of increasing concern amongst parents, educationalists and policy makers, yet little research has been conducted with young people themselves to explore their perspectives on the support they need to navigate relationships in the new digital media landscape. To address this absence, an inter-disciplinary team of researchers undertook a participatory study with students, aged 13 to 15, in a UK secondary school. This paper outlines key study findings, including young people’s views on sexting, their recommendations for improved education around sexting in schools, their preferred sources of support, and their perspectives on the way adults should respond to young people’s sexting. Findings indicate that sexting education needs to be developed within the context of wider relationship issues, such as gender, power dynamics and trust between peers, and improved communication between students and teachers or other responsible adults. Findings may be used to consider ways of designing and communicating messages around sexting to young people within and beyond educational settings.     

Explaining phonology and reading in adult learners: Introducing prosodic awareness and executive functions to reading ability

Background

This study was designed to extend our understanding of phonology and reading to include suprasegmental awareness using measures of prosodic awareness, which are complex tasks that tap into the rhythmic aspects of phonology. By requiring participants to access, reflect on and manipulate word stress, the prosodic awareness measures used here necessarily impose demands on the executive system. Prosodic awareness was evaluated as a phonological predictor of reading in older readers while controlling for executive functions (EF) in order to ascertain whether observed predictive relationships could be confidently attributed to suprasegmental awareness.

Methods

103 adults between 18 and 55 years of age completed tasks on prosodic awareness, EF, vocabulary, nonverbal abilities, naming speed and short‐term memory.

Results

Independent contributions of prosodic awareness added to models of word reading, whereas EF processes did not uniquely contribute to adult reading outcomes.

Conclusions

Suprasegmental phonology explains individual differences in word reading among experienced readers. Theoretical implications of findings are discussed.

Implications for Practice

What is already known about this topic

• Phonological awareness (PA) becomes less predictive of reading in older readers. PA is typically assessed at the level of the segment (e.g., phonemes, syllables and onset‐rimes), with less focus on suprasegmental processes (e.g., rhythm, stress and intonation).
• Suprasegmental phonological processing includes measures of prosodic ability (e.g., awareness and manipulation of suprasegmental features of oral language). Studies on prosodic awareness and reading have independent contributions beyond segmental PA in early readers. Less work has been investigated among adult readers.
• Executive functions (EF) including inhibitory control, working memory, switching and updating and monitoring of goal directed behaviour, predict overall academic achievement. Limited studies have controlled for EF demands in phonological tasks.

What this paper adds

• Tasks of prosodic awareness necessarily impose demands on the executive system when manipulating components of oral language. After controlling for EF and controls, prosodic awareness explained individual differences in adult word reading.
• Tasks of suprasegmental phonological processes explain the association between phonology and reading in older and more experienced readers. Researchers who explore phonology and reading development should begin to include tasks of prosodic awareness to examine the dual role of segmental and suprasegmental PA as it is implicated across development.

Implications for theory, policy or practice

• Theoretical models of phonology and reading can be extended to include suprasegmental processes.
• For educational practitioners involved in reading assessment of older readers, tasks of prosodic awareness are a more age‐appropriate measure of phonology.
• Tasks of phonology and reading with increasing complexity impose greater demands on the executive system. The relationship between cognitive flexibility and reading needs to be considered in theoretical models of reading.

     

The role of stress processing abilities in the development of bilingual reading

French and Dutch differ regarding the manifestations and lexical functions of the stress pattern of words. The present study examined group differences in stress processing abilities between French‐native and Dutch‐native listeners, thus extending previous cross‐linguistic comparisons involving Spanish‐native and French‐native adults. The results show that Dutch‐native first‐graders significantly outperformed French monolinguals, and that French‐native listeners schooled in Dutch produced intermediary performances, suggesting that stress‐processing abilities are a learnable set of skills. The present study also examined the contribution of stress processing abilities to reading development in Dutch, a stress‐based language, compared to that in French, a syllable‐based language. Although the expected correlation between stress processing abilities and reading was not observed in the Dutch monolinguals, such correlation was observed in the French‐native bilinguals schooled in Dutch and not in the Dutch‐native bilinguals schooled in French. This suggests that stress processing abilities influence reading development in a second, stress‐based, language. Moreover, the monolinguals and bilinguals schooled in Dutch showed significant associations between lexical development and stress processing abilities. Ways in which prosody might be involved in lexical and reading development are explored and discussed.     

The Test's the Thing: viewpoints of students with special educational needs

This paper presents views on testing by a cross‐cultural sample of primary and secondary students with special educational needs. While some of the responses indicated that tests were useful for feedback and motivation, half of the sample disliked having tests and found them boring. These negative views were intensified by the marks that the students received and the physical and emotional effects during the testing. As the students viewed tests and assessment as necessary components of school life, the paper concludes that children with special educational needs are entitled to help to overcome their anxieties and that positive classroom practice can help to effect this.     

Coûts Et Financement De L’Alphabétisation

While the costs of literacy programmes continue to outstrip the resources available, this article argues that much can be done by bringing more efficiency and clarity into accounting and financing procedures. Drawing on the example of Senegal, the author argues for more effective methods of calculating the costs of programmes, analysing the various cost components, managing budgets and evaluating cost- effectiveness. He also points out the need for partnership between different sectors and emphasizes that political stability is very important for positive results.     

A comparison of the Stanford-Binet Intelligence Scale and the McCarthy Scales of Children's Abilities with preschool children

The purpose of the present study was to determine the degree to which performance on the McCarthy Scaies of Children's Abilities correlated with performance on the Stanford-Binet for a group of preschoolers. The sample consisted of 44 children ranging in age from 3–11 to 5–4. It was found that the General Cognitive Index scores of the McCarthy Scales correlated well with the Stanford-Binet IQ scores, r^xy = .90. However, 40 of the 44 subjects scored higher on the Stanford-Binet than on the McCarthy Scales.     

Comparison of physiological responses to graded exercise test performance in outrigger canoeing

The aim of this study was to establish a graded exercise test protocol for determining the peak physiological responses of female outrigger canoeists. Seventeen trained female outrigger canoeists completed two outrigger ergometer graded exercise test protocols in random order: (1) 25 W power output for 2 min increasing by 7.5 W every minute until exhaustion; and (2) 25 W power output for 2 min increasing by 15 W every 2 min to exhaustion. Heart rate and power output were recorded every 15 s. Expired air was collected continuously and sampled for analysis at 15-s intervals, while blood lactate concentration was measured immediately after and 3, 5, and 7 min after exercise. The peak physiological and performance variables examined included peak oxygen uptake (VO2peak), minute ventilation, tidal volume, ventilatory thresholds 1 and 2, respiratory rate, respiratory exchange ratio, heart rate, blood lactate concentration, power output, performance time, and time to VO2peak. There were no significant differences in peak physiological responses, ventilatory thresholds or performance variables between the two graded exercise test protocols. Despite no significant differences between protocols, due to the large limits of agreement evident between protocols for the peak physiological responses, it is recommended that the same protocol be used for all comparison testing to minimize intra-individual variability of results.     

Managing a Resident Volunteer Program at a Remote Research Station

Museums are ideal institutions for the development of volunteer programs. A museum's commitments to education and research and to expansion of learning, as well as its physical resources, offer potentially attractive forms of involvement for various segments of the population. We discuss aspects of a long‐established, self‐funded resident volunteer program that integrates the resources of a museum's field station with seasonal staffing needs, resulting in economic benefits to the museum and educational and career‐advancement benefits to volunteers. The practices used to bring together these objectives are discussed, with the goal of providing an example for museum administrators so they might better appreciate the potential diversity of volunteer programs as methods of broadening museums' roles in society.     

Use of an abbreviated version of the WISC-R with learning disabled children

The Wechsler Intelligence Scale for Children-Revised (WISC-R) was administered to 56 learning disabled children, using standard assessment procedures and format as outlined by Wechsler. Abbreviated IQ scores were then derived by applying the Kennedy-Elder formula, and equation that uses five WISC-R subtests with varied weightings. Comparisons between the standard IQ scores and the abbreviated IQ scores were evaluated. A Pearson product-moment correlation coefficient of .83 and a non-significant t-test between the mean IQs suggested the two scores were interchangeable. However, frequent IQ classification changes (23%) rendered the K-E format unacceptable for this population.
