Speech and Language Difficulties in Children With and Without a Family History of Dyslexia

According to recent psychological theories of situation model construction, readers routinely and quickly construct inferences that elaborate causal antecedents of explicit events in the text, but not inferences about causal consequences. The process of forecasting lengthy causal chains into the future is taxing on working memory, so these inferences are either not constructed or their construction consumes a comparatively large amount of reading time. This study collected self-paced sentence reading times from younger and older adults who read expository texts on scientific and technological mechanisms. Readers were also measured on working memory span, general world knowledge, reasoning ability, and reading frequency. Multiple regression analyses on the reading times revealed that (a) causal consequence inferences were more time consuming than causal antecedent inferences and (b) noncausal elaborative inferences were not constructed. The pattern of beta weights for inference variables was remarkably similar for younger and older adults and was unaffected by other measures of individual differences. The process of constructing causal inferences is therefore stable and predictable across different groups of readers.     

Probabilistic Cues to Grammatical Category in English Orthography and Their Influence During Reading

We investigated probabilistic cues to grammatical category (noun vs. verb) in English orthography. These cues are located in both the beginnings and endings of words—as identified in our large-scale corpus analysis. Experiment 1 tested participants' sensitivity to beginning and ending cues while making speeded grammatical classifications. Experiment 2 tested sensitivity to these cues during lexical decisions. For both tasks, words with consistent ending cues (with respect to grammatical category) were processed more quickly and with lower error rates than words with inconsistent ending cues. However, for beginnings, consistent cues resulted in lower errors but no differences in response times. The data reported here point to the multifaceted nature of grammatical category representation and indicate that probabilistic orthographic cues relating to grammatical category have a clear influence on lexical processing particularly when these cues are located at the end of the word.     

Física para simples mortales

La comprensión de las relaciones y leyes físicas depende, como se analiza en este artículo, del modo en que se represente éstas el alumno. El predominio de sistemas matemáticos de explicación e intuición de las leyes físicas—la vía cuantitativa—parece producir una visión opaca de esas leyes y lleva a errores graves de comprensión, pese a la correcta, pero inestable aplicación puntual de fórmulas.

En este artículo se exponen nuevos métodos de enseñanza de la física por ordenador que presentan entornos interactivos cuasi-reales—micromundos—y que se basan en sistemas visuales—vía cualitativa—haciendo así transparentes los procesos físicos tradicionalmente ocultos tras el ropaje notacional de los operadores matemáticos.     

Effect of Guided Practice on Overhand-Throw Ball Velocities of Kindergarten Children

Abstract

Forty-five children from two intact kindergartens in one school were randomly assigned by sex to (a) an experimental group which received a movement program that included 120 min of guided practice in the overhand throw; or (b) a control group which received the same movement program but no exposure to the throw. A third group (N = 24), randomly selected by sex from a comparable school, received no movement program. Before and after the eight-week instructional period, ten trials of each child's overhand throw for force were filmed. Horizontal ball velocities were simultaneously recorded. ANOVAs on pre- and posttest ball velocities for each sex within each treatment group revealed no significant practice effect over ten trials (p > .05); thus, the trial mean was used as each subject's score. Two-way ANOVAs (treatment X sex) on the pre- and posttest data indicated no significant velocity differences (p > .05) between groups either before or after instruction. Boys had significantly greater velocities than girls (p < .05). Eight weeks of instruction that included 120 min of guided practice in the overarm throw did not significantly change the ball velocities of kindergarten children when compared to two groups with no formal throwing experience.     

Effects of math anxiety and perfectionism on timed versus untimed math testing in mathematically gifted sixth graders

This study was designed to examine the effects of math anxiety and perfectionism on math performance, under timed testing conditions, among mathematically gifted sixth graders. We found that participants had worse math performance during timed versus untimed testing, but this difference was statistically significant only when the timed condition preceded the untimed condition. We also found that children with higher levels of either math anxiety or perfectionism had a smaller performance discrepancy during timed versus untimed testing, relative to children with lower levels of math anxiety or perfectionism. There were no statistically significant gender differences in overall test performance, nor in levels of math anxiety or perfectionism; however, the difference between performance on timed and untimed math testing was statistically significant for girls, but not for boys. Implications for educators are discussed.     

The impact of education level and type on moral reasoning

The importance of education in developing morally sensitive individuals who use principled moral reasoning when facing dilemmas has been widely acknowledged. In the context of the criticism levelled at the Irish higher education system for failing to fulfil the role of intellectual leader and moral critic within the public domain, this paper examines the impact of education level (both undergraduate and post-graduate) and type (arts or technical/profession-based) on moral reasoning using 311 Irish participants from a wide variety of educational backgrounds. An enhanced understanding of the impact of education on moral reasoning will facilitate the development of educational initiatives aimed at augmenting moral reasoning in higher-level students.     

Creating a ‘third space’ in the context of a university–school partnership: supporting teacher action research and the research preparation of doctoral students

The focus of the Education Works Personalization Project was to facilitate teams of teacher action researchers whose goal was to personalize their teaching with the support of university partners including doctoral students in education. The subsequent apprentice-like research experience within this university–school partnership provided an opportunity to study the ways in which teacher action research could serve as a vehicle for bridging the culture gap between schools and universities. Both the research team experience and the development of the school–university inquiry/knowledge network were initially characterized by undefined roles accompanied by ambiguous expectations. Although the ambiguity proved difficult initially, those who persisted and engaged in new roles ultimately found these emerging inquiry communities generative and valuable. We have come to conceptualize these generative inquiry communities as third spaces and we describe how oppositional categories framed by the cultural differences between schools and universities can work together to generate new knowledge.     

How PETE comes to matter in the performance of social justice education

ABSTRACT

Background: For over four decades, there have been calls for physical education (PE) and physical education teacher education (PETE) to address social inequality and foster social justice. Yet, as numerous studies demonstrate, attempts to educate for social justice in PETE are infrequent and rarely comprehensive. This raises the question why it appears to be possible in some situations but not others, and for some students and not others.

Purpose: The purpose of this paper is to examine the multiple socio-political networks or assemblages in which PETE is embedded and explore how these shape the possibilities for students to engage with the concept of social justice and sociocultural issues (SCI) when learning to teach PE. Two research questions guided this study: How does an orientation for social justice education (SJE) within education policy affect the standards for enacting PETE programs? How is SJE encouraged within PETE programs?

Methodology: Drawing from a broader study of over 70 key personnel in more than 40 PETE programs, we examined how faculty in PETE understand their professional world, identify their subjective meanings of their experiences, and address SCI andSJE within PETE. Data sources included an initial survey, a semi-structured interview, and program artifacts. We analyze the ways that SJE/SCI was represented in three national settings (England, the United States, and New Zealand) and identified common themes.

Results: Examination of each national setting reveals ways that SJE and SCI were enabled and constrained across the national, programmatic, and individual level in each of the countries. The coherence of explicit National policy and curricula, PETE program philosophies, and the presence of multiple individual interests in social justice served to reify a sociocultural agenda. Conversely, possibilities were nullified by narrow or general National Standards, programs that failed to acknowledge sociocultural interests, and the absence of a critical mass of actors with a socio-critical orientation. These differences in assemblage culminated in variations in curriculum time that served to restrict or enable the breadth, frequency, and consistency of the messages surrounding SCI in PETE.

Conclusion: These findings highlight the importance of acknowledging socio-political networks where PETE operates. The agency of PETEs to enact pedagogies that foreground sociocultural interests is contingent on congruity of the networks. The authors caution that although the ‘perfect storm’ of conditions has a profound influence of the possibility of transformational learning of SCI in PETE, this arrangement is always temporary, fluid, and subject to changes in any of the three network levels. Additionally, the success of PETE in enabling graduating PE teachers to recognize the inequities that may be reinforced through the ‘hidden curriculum’ and to problematize the subject area is contingent on the expectations of the schools in which they teach.
