One Model or Two? Sentence Verification in Children and Adults

We employed the sentence‐picture verification paradigm to ask whether children are more likely than adults to construct unitary representations of ambiguous sentences. Six kinds of sentence were presented with the two kinds of inherently ambiguous sentences being: “There are crosses either above or below the line” and “There are crosses above [below] the line”. These sentences are inherently ambiguous because they afford both ‘inclusive’ and ‘exclusive’ readings, the readings being determined by whether subjects judge a picture with crosses both above and below a line to be true of the sentences. In Experiment 1, which had a sentence‐picture order, and in Experiment 2, which had a picture‐sentence order, the verification reaction‐time and the true/false judgement data together suggested that the younger subjects were more likely to construct unitary representations for the ambiguous sentences. Our strongest evidence for this claim was that children are heavily biased towards an inclusive reading of disjunction. Analysis of the sentence reading times in Experiments 1 and 3 suggested that children, unlike adults, may be deferring the construction of a mental model of the disjunctive sentence until the picture arrives.     

The relationship between research self-efficacy,research disposition and publication output

The study had two main aims: (i) to develop a model incorporating research self-efficacy and research disposition as predictors of publication output; and (ii) to assess the fit and robustness of this model to dichotomous groups based on gender, academic qualifications and rank. Data were drawn from a survey of lecturers (n = 331) working in two large Australian universities. The survey response rate was 33.6% and the lecturers were affiliated with a diverse range of research disciplines. Well-fitting measurement models for both research self-efficacy and disposition were produced using AMOS. However, a structural model which included these two measurement models would not satisfactorily fit the full sample. Subsequent testing yielded acceptable results when separate analyses employing the group variables of gender, academic qualifications and rank were undertaken. The model with rank offered the best fit of the data and, across all models, research self-efficacy proved to be the most important predictor of output. The results of the study provide an understanding of the scope and nature of research self-efficacy and, in addition, contribute to knowledge about the factors that underlie research disposition. As a consequence, the results have implications for career development programmes designed to foster research skills and further research. Additionally, the results point to some possible interventions aimed to boost research endeavour and output.

Young Adult Fairy Tales for the New Age: Francesca Lia Block's The Rose and the Beast

Francesca Lia Block's The Rose and the Beast attests to the resilience of the traditional folktale form. Block's work is a modern adaptation of some of the most familiar old tales, all with heroines struggling against a plastic, soulless culture beset by drugs, sex, and violence. Her heroines in these feminist retellings survive not with the help of magic but by their own ingenuity and resourcefulness. Using the folktale template, Block conveys her often strong social messages (the destructiveness of sexual violence or drug abuse, for example) with stark symbolism, surreal settings, and deceptive simplicity. The results are powerful, revisionist tales that ultimately celebrate the triumph of love—in all its manifestations—as the antidote to the neuroses of contemporary American society.     

Educational practitioners’ beliefs and conceptualisation about the cause of ADHD: A qualitative study

Objectives: Educational practitioners play an important role in the referral and treatment of children with attention-deficit/hyperactivity disorder (ADHD). This study aimed to explore how educational practitioners conceptualise their beliefs about the causes of symptoms of ADHD. Method: Forty-one educational practitioners from schools in the United Kingdom participated in focus groups or individual interviews. Data were analysed using thematic analysis. Results: Practitioners’ beliefs fell into two categories: biological and environmental. Practitioners conceptualised the causes of ADHD in lay-theoretical models: a ‘True’ ADHD model considered that symptoms of ADHD in many cases were due to adverse environments; and a model whereby a biological predisposition is the root of the cause of the child’s symptoms. Conclusion: Differential beliefs about the causes of ADHD may lead to practitioners blaming parents for a child’s behaviour and discounting ADHD as a valid condition. This has implications for the effective support of children with ADHD in schools.     

A 30-Year Scoping Review of the Physical Education Teacher Satisfaction Literature

While stress has always been present in the teaching profession, recent trends such as standardized testing and school and teacher accountability may be making teachers’ work more stressful. Teacher satisfaction research has emerged as a popular lens through which to understand how teachers experience their work. This scoping review sought to summarize the literature related to physical education teacher satisfaction published between 1987 and 2016. A total of 20 articles that reported research from 11 different countries were identified for inclusion. Thematic analysis of the study results led to the construction of four themes: (a) levels of physical education teacher satisfaction vary by level and context; (b) demographic variables do not reliably predict satisfaction; (c) intrinsic and psychosocial variables influence job satisfaction; and (d) the workplace and interpersonal relationships influence job satisfaction. Results are discussed and recommendations provided, particularly related to a theoretical basis for future research and methodological diversity.     

Computer Experience,School Support and Computer Anxieties

Past research has shown computer anxiety to be present in a sizeable minority of school teachers, and has identified some of the personal and school‐based correlates of this anxiety. Before effective interventions can be introduced, however, more needs to be known of the various forms and sources of this problem. The current study involved a survey of the experiences, attitudes and anxieties of a random sample of 350 Australian primary and secondary school teachers. Levels of self‐rated computing competence among these teachers were moderately low. Computing competence and anxiety were highly correlated, r= ‐ 0.78. Three distinctive types of computer anxiety were identified, as was a set of factors predictive of each. As hypothesised, computer anxieties were inversely related to the quality of prior computer learning experiences, and to the extent of current school support for computer usage. Implications for the reduction of computer anxiety among teachers are discussed.     

Learning from programmed instruction: Examining implications for modern instructional technology

This article reports a theoretical examination of several parallels between contemporary instructional technology (as manifest in one of its most current manifestations, online learning) and one of its direct predecessors, programmed instruction. We place particular focus on the unterlying assumptions of the two movements. Our analysis suggests that four assumptions that contributed to the historical demise of programmed instruction—(a) ontological determinisms, (b) materialism (c) social efficiency, and (d) technological determinism—also underlie contemporary instructional technology theory and practice and threaten its long-term viability as an educational resource. Based on this examination, we offer several recommendations for practicing instructional technologists and make a call for innovative assumptions and make a call for innovative assumptions and theories not widely visible in the field of instructional technology.     

Sex differences in rats’ stationary-cage activity measured by observation and automatic recording

Rats’ stationary-cage activity was measured using simultaneous observational time sampling and automatic recording via photobeams. Females scored higher than males on the combined observational categories of rearing, ambulating, and sniffing, but lower on grooming, eating, and drinking, with these differences consistent across 9 days of confinement and across time of day of observation. There were no sex differences in the time spent inactive or in the number of photobeam breaks. Beam breaks were related positively to sniffing and inversely to inactivity. The results raise questions regarding the interpretation of sex differences in behavior in novel and familiar environments and provide evidence on the comparability of observational and automatic methods of activity measurement.
