The Impact of Early Social Interactions on Later Language Development in Spanish–English Bilingual Infants

This study tested the impact of child‐directed language input on language development in Spanish–English bilingual infants (N = 25, 11‐ and 14‐month‐olds from the Seattle metropolitan area), across languages and independently for each language, controlling for socioeconomic status. Language input was characterized by social interaction variables, defined in terms of speech style (“parentese” vs. standard speech) and social context (one‐on‐one vs. group). Correlations between parentese one‐on‐one and productive vocabulary at 24 months (n = 18) were found across languages and in each language independently. Differences are highlighted between previously published monolingual samples, which used the same methods as the current study of bilingual infants. The results also suggest cultural effects on language input and language development in bilingual and bicultural infants.     

Differences Between Attached and Detached Cadaveric Prosections on Students' Identification Ability During Practical Examinations

Cadaveric prosections are effective learning tools in anatomy education. They range from a fully dissected, sometimes plastinated, complete cadaver (in situ prosections), to a single, carefully dissected structure detached from a cadaver (ex situ prosections). While most research has focused on the advantages and disadvantages of dissection versus prosection, limited information is available on the instructional efficacy of different prosection types. This contribution explored potential differences between in situ and ex situ prosections regarding the ability of undergraduate students to identify anatomical structures. To determine if students were able to recognize the same anatomical structure on both in situ and ex situ prosections, or on either one individually, six structures were tagged on both prosection types as part of three course summative examinations. The majority of students (61%–68%) fell into one of the two categories: those that recognized or failed to recognize the same structure on both in situ and ex situ prosections. The percentage of students who recognized a selected structure on only one type of prosection was small (1.6%–31.6%), but skewed in favor of ex situ prosections (P ≤ 0.01). These results suggest that overall students' identification ability was due to knowledge differences, not the spatial or contextual challenges posed by each type of prosection. They also suggest that the relative difficulty of either prosection type depends on the nature of the anatomical structure. Thus, one type of prosection might be more appropriate for teaching some structures, and therefore the use of both types is recommended.     

The Stranger: Adventures at zero point

Abstract

In one of his notebooks, Albert Camus describes, The stranger, The myth of Sisyphus, Caligula and The misunderstanding as pertaining to a series; a schema that suggests that if one were to write about one of these literary works, one would be writing about parts of a whole unless one also engaged with the others. Whether one does this or not, may or may not reflect the nature of the relationship one sees these texts as sharing. The stranger and The myth of Sisyphus share something unique: they are both as Camus describes them, zero points; a zero point here being understood as the zero point at which one thinks about one’s existence. This article begins with a reflection upon the relative philosophical value of understanding The myth of Sisyphus as a work of art and then occupies itself with how this understanding might provide an opportunity for self-reflection when reading The stranger. The reading of The myth of Sisyphus is not used so much to better understand Meursault (the protagonist of The stranger) and his story but to invert our interpretative methodology such that it is possible to speak to the reader as a significant actor. The novel is thought of in terms of the gifting of a philosophical problem, a problem which the author of this article attempts to understand from the point of view of how one might see oneself as paradoxically implicated in the drama of its articulation. It is this paradox that will lead us to speak of the narrative of The stranger as referring to a problem in how philosophy speaks to our experience of education.     

‘But this isn’t school’: exploring tensions in the intersection between school and leisure activities in classroom game design

While there are several positive outcomes from implementing game design in a formal learning context, there are also challenges that have to be considered in order to improve game-based learning. This is explored in the article, using the concepts of activity frames and stancetaking, focusing on the social organization of the game design activity. Building on video data from one 6th grade class and one 7th grade class designing computer games based on their social studies curriculum, this article shows that tensions arise when students fail to agree on what the activity they are doing is really about: The academic content and what students commonly perceive as school activities, or a game design activity informed by their leisure time. The main argument is that the students position themselves as students, game designers or characters, and that this may cause tensions in the students’ social interactions.     

The impact of new public management instruments on PhD education

New public governance emphasises less state, more market and more hierarchy as the cornerstones for effective steering of higher education institutions. Based on an explorative analysis of qualitative and quantitative data of fourteen German and European economics departments, we investigate the steering effects of six new public management instruments in the years 2001 and 2002 on subsequent placement success of PhD graduates. Using crisp set Qualitative Comparative Analysis to analyse the data, our results deliver strong support for the positive effects of competition for resources and the varying effects of hierarchy on PhD education. Governance of successful departments is characterised by two solutions: transparency over academic achievements as one single success factor in each solution or a combination of additional funding based on national competitive performance with either no public policy regulations for departments or no university regulations for departments. Governance of unsuccessful departments is characterised by one solution: university regulations for departments or a combination of no additional funding based on national competitive performance and no transparency over academic achievements. Our results strengthen the strong impact of selected competitive mechanisms as an effective governance instrument and the partially detrimental effects of state regulations. University regulations turn out to be successful if they increase transparency over academic achievements by faculty members. Success is unlikely if those rules intervene into PhD education.     

Girls and science education in Mauritius: a study of science class practices and their effects on girls

Background: The population of Mauritius consists of 52% females and scientific literacy is seen to be of vital importance for all young people if they are to be sufficiently equipped to meet the challenges of a fast changing world. Previous research shows, however, that science is not popular among girls. This paper explores one of many reasons why few girls opt for science subjects after compulsory schooling.

Purpose: This study investigated the approaches to teaching in four science classrooms in Mauritius, with particular emphases on the preferences of girls as they learn science.

Sample: A total of 20 student interviews and 16 teacher interviews were conducted in four schools in Mauritius. The four mixed-faith schools comprised two all-girl schools (one state, one fee-paying), and two mixed-sex schools (one state, one fee-paying), within urban, suburban and rural situations.

Design and method: 80 non-participant lessons were observed, of which 60 were science lessons while the remaining 20 non-science lessons were in economics, accounts and commerce. Group interviews with five pupils in each of the four schools were conducted and 16 individual interviews with teachers in the four schools gave an insight into the pedagogic approaches used for the teaching and learning of science.

Results: Transmissive approaches to teaching, giving little opportunity for collaborative or activity-based learning, were found to be the most important factors in alienating the girls from science.

Conclusions: There need to be radical changes in approaches to teaching to retain young girls’ interest in the sciences.     

An investigation of Grade 5 children's knowledge of the doubling rule in spelling

The goal of this study was to investigate Grade 5 children's knowledge of a common word pattern in English, to double the final consonant of a one‐syllable word when adding –ed. Significant correlations were found between –ed spelling and general spelling ability, as well as correct pronunciation of –ed words in isolated word reading and spelling. The correlation between –ed spelling and –ed word reading (r=0.31) is lower than one would expect to find in general spelling and reading ability. Individual interviews were conducted to assess children's explicit awareness of the doubling rule, followed by a measure of consistency in spelling a selected number of –ed words. Performance on an artificial grammar task indicated a correlation between implicit learning of nonsense letter strings and spelling ability. Overall results point to the unstable nature of children's knowledge of the doubling rule. Implications for instruction are discussed.     

What Develops in Infants’ Spatial Categorization? Korean Infants’ Categorization of Containment and Tight‐Fit Relations

Korean‐learning infants’ categorization of two spatial categories, one consistent and one inconsistent with the Korean semantic category of “kkita,” was examined. Infants of 10 months (n = 32) and 18 months (n = 49) were tested on their categorization of containment or tight fit spatial relations. At 10 months, infants only formed a category of containment, but at 18 months, their categorization of tight fit was significantly stronger than containment. The results suggest that Korean infants benefit from their language environment in forming a category of tight fit when the exemplars are perceptually diverse. In particular, infants’ language environment may bolster their ability to generalize across diverse exemplars to form abstract categorical representations of spatial relations.     

What they're reading: A theory of patience

When About Campus polled students and professors on what books they would recommend to help people understand other races and cultures, one book kept surfacing, Racism 101 by Nikki Giovanni. For that reason, and in honor of this issue, we decided to devote the entire “What They're Reading” column to a short chapter from Racism 101.     

High school students’ implicit theories of what facilitates science learning

Background: Research has primarily concentrated on adults’ implicit theories about high quality science education for all students. Little work has considered the students’ perspective. This study investigated high school students’ implicit theories about what helped them learn science.

Purpose: This study addressed (1) What characterizes high school students’ implicit theories of what facilitates their learning of science?; (2) With respect to students’ self-classifications as African American or European American and female or male, do differences exist in the students’ implicit theories?

Sample, design and methods: Students in an urban high school located in south-eastern United States were surveyed in 2006 about their thoughts on what helps them learn science. To confirm or disconfirm any differences, data from two different samples were analyzed. Responses of 112 African American and 118 European American students and responses from 297 European American students comprised the data for sample one and two, respectively.

Results: Seven categories emerged from the deductive and inductive analyses of data: personal responsibility, learning arrangements, interest and knowledge, communication, student mastery, environmental responsiveness, and instructional strategies. Instructional strategies captured 82% and 80% of the data from sample one and two, respectively; consequently, this category was further subjected to Mann-Whitney statistical analysis at p < .05 to ascertain ethnic differences. Significant differences did not exist for ethnicity but differences between females and males in sample one and sample two emerged.

Conclusions: African American and European American students’ implicit theories about instructional strategies that facilitated their science learning did not significantly differ but female and male students’ implicit theories about instructional strategies that helped them learn science significantly differed. Because students attend and respond to what they think and perceive to be important, addressing students’ implicit theories may be one way to enhance science education reform.

EDITORIAL

Novice nurses encounter numerous factors that impact on their learning in the complex healthcare workplace. Registered nurses often work one‐on‐one with novices as preceptors to facilitate the development of novices’ clinical skills and socialisation into the profession. This paper explores the concept of preceptorship from novice nurses’ and preceptors’ perspective, drawing upon data from a project between a large healthcare organisation and a university in Melbourne, Australia. The study, framed in ethnomethodology, included fieldwork observation, interviews and student surveys; this paper focuses on data collected over a series of individual interviews with nursing students (n = 28) and preceptors (n = 25). Thematic analysis yielded six key themes: workplace socialisation, empathy, individuality, willingness to engage, changing support and a realisation [by novices about the preceptor role]. Findings highlight the complexity of workplace learning that is influenced by the idiosyncrasies of the individuals involved and the social milieu in which the learning takes place.     

Implicit Knowledge of Word Stress and Derivational Morphology Guides Skilled Readers’ Decoding of Multisyllabic Words

In oral language, morphologically conditioned regularities around stress assignment can be found in two classes of derivational suffixes, one that causes lexical stress to shift to the syllable immediately preceding the suffix (ACtive – acTIVity) and one that has no effect on stress (SILLy – SILLiness). In this study, adults listening to spoken “derived” nonwords judged as preferable those wherein the stress placement was consistent with morphological regularities of English. When reading nonwords and a set of nonwords derived from them, readers reliably assigned stress to the syllable predicted by the morphology. This effect was significantly associated with scores on standardized measures of word reading after controlling for nonword reading ability, showing that the relationship was not merely an artifact of decoding skill. These findings support the importance of the interface between morphology and suprasegmental phonology as a key factor in the way English-speaking readers approach multisyllabic, morphologically complex words.     

Estimation of the J-resistance curve for Cr2Ni2MoV steel using the modified load separation parameter S_（pb） method

Based on load separation theory, the load separation parameter Spb method is an effective approach for estimating the J-resistance curve from records of load versus displacement directly, using one sharp cracked specimen and an additional reference blunt cracked specimen. However, the effect of the reference blunt cracked specimen on J-resistance determination was not explicitly considered in past work. In this paper, a modified load separation parameter Spb method was developed to eliminate this effect, and then a unique estimation of instantaneous crack length for one sharp cracked specimen could be obtained. Furthermore, a forced blunting calibration method was also adopted to determine the instantaneous crack length in the load inseparable region, referring to a normalization method. Experiments on steam turbine rotator steel Cr2Ni2MoV were carried out to estimate J-resistance curves using an unloading compliance method. By removing unload and reload data from load-displacement records, the J-resistance curve for the same sharp cracked specimen was estimated using the modified separation parameter Spb method. The results indicate that the modified Spb method completely eliminates the effect of the reference blunt cracked specimen on the instantaneous crack length determination of the sharp cracked specimen. However, different J-resistance curves in a small range of crack extension are present when different blunting coefficients are used in the blunting line equation. The J-resistance curve obtained from the modified Spb method agrees well with that obtained from the compliance method.     

THE POSSIBLE ROLE OF THE COUNCIL OF EUROPE IN ASSISTING THE DEVELOPMENT OF SCIENCE IN CENTRAL AND EASTERN EUROPEAN COUNTRIES

Most of this article consists of the reproduction of Recommendation No. R (95) 7 of the Committee of Ministers [of the Council of Europe] to Member States on Brain Drain in the Sectors of Higher Education and Research, adopted by the Ministers’ Deputies on 2 March 1995 and of its Annex consisting of a set of concrete measures to be taken in order to enact and to support the Recommendation. The Recommendation and Annex statements are preceded by two background statements, one suggesting ways in which the Council of Europe might aid the development of science and science policy in the countries of central and eastern Europe undergoing transition, the other, giving the background to Recommendation No. R (95) 7.     

Peer Relationships Across the Preschool to School Transition

Research Findings: The aim of this longitudinal study was to explore peer relationships across the transition from preschool to school. Participants were 35 (17 male) children attending the Irish preschool initiative Early Start (M age = 49.31 months). Sociometric measures were employed on two occasions: at the end of preschool and in the first year of school. Results indicated that most preschoolers (83%) had at least one mutual friend, and by school age all children had at least one mutual friend. Almost one third (29%) of preschools and school-age children had a mutual best friend. Notably, all children made new friends in school. In addition, a number of friendships (18%) survived the preschool to school transition. Correlational analysis also suggested some stability in peer relationships from preschool into the first year of school. Exploratory multiple regression analyses showed that preschool peer variables predicted friendship status and social preference in school. Furthermore, best friendship in preschool uniquely predicted friendship in school, and best friend status in school was uniquely associated with social preference in school. Practice: Results have implications for parents' and early educators' promotion of children's friendships during the transition from preschool to school.     

The Missing Element to Achieving a Citizenship-as-Practice: Balancing Freedom and Responsibility in Schools Today

The new Social Studies curriculum recently introduced in Alberta proposes to encourage students to affirm their place as citizens in a democratic society. Grounded in Biesta’s (2007) argument that regardless of a Program of Studies’ best stated goals and intentions, if a school is not structured democratically the chances of the program being successful are limited. In this article, I question what makes a school democratic as opposed to undemocratic by proposing that the new curriculum is grounded in a representational view of knowledge which leads to a document that is overly conceptualized and presents a view of citizenship as one that can be achieved rather than one that is practiced (Biesta & Lawy, 2006). I argue that it is the representational curriculum and the public school’s organizational structure with its emphasis on duties and responsibilities and the virtual absence of freedom and rights that make these schools fundamentally undemocratic places. In order to pursue this line of inquiry, I juxtapose schools in the public system with a private school which claims to be a participative democracy. This juxtaposition revealed that a school that gives students freedom first and trusts that they will act responsibly with it, is more likely to lead to a citizenship that is practiced rather than one that is simply achieved. While it is not the intention of this paper, to recommend that all schools adopt the model of the private school in this study, it does help us understand why Biesta (2007) is not overly optimistic regarding schools being able to achieve a citizenship that is practiced as opposed to one that is achieved.     

Concept map structure,gender and teaching methods: an investigation of students' science learning

Background: This study deals with the application of concept mapping to the teaching and learning of a science topic with secondary school students in Germany.

Purpose: The main research questions were: (1) Do different teaching approaches affect concept map structure or students' learning success? (2) Is the structure of concept maps influenced by gender? (3) Is the concept map structure a reliable indicator of students' learning success?

Sample: One hundred and forty-nine high-achieving 5th-grade students from four German secondary schools participated in the study. The average age of participants was 10½ years. Gender distribution was balanced. Students produced concept maps working in small, single-sex groups.

Design and methods: There were two teaching approaches used: one based upon teacher-centred instruction and one consisting of student-centred learning. Both were followed by a concept-mapping phase. Student groups experienced either one or the other teaching approach. Concept map structures were analysed using of the method of Kinchin, Hay and Adams. We defined three different possible types of concept map structure: spokes, chains and nets. Furthermore, for assessing a student's short- and longer-term learning success, we constructed a multiple-choice knowledge test applied in a pre-, post-, retention-test design. Parametric tests, such as MANOVA, one-way ANOVA and t-tests were used to identify any differences in gender, teaching approach, number of nets per concept map and their interactions.

Results: Type of teaching approach had an effect on concept map structure but not on students' longer-term learning success. Students of the teacher-centred approach produced more net structures than those students who participated in the hands-on instruction. Subsequent analyses showed in total more net structures for female groups. The interaction of gender and number of nets per concept map showed a significant effect on students' longer-term learning success.

Conclusion: The study suggests that Kinchin's classification scheme for assessing concept map quality may be a good indicator of students' learning success when applied in combination with a knowledge test.     

Bacteremia due to Rhodococcus equi：a case report and review of the literature

Rhodococcus equi, previously known as Corynebacterium equi, is one of the most important causes of zoonotic infections in grazing animals. Increased cases of human infection with R. equi have been reported, especially in immunocompromised patients, within recent years. We present a case of R. equi bacteremia in a 51-year-old man with diabetes and liver cirrhosis, on long-term corticosteroid therapy after skin-grafting surgery. The patient recovered soon after he was treated with vancomycin. This review focuses on the microbiological characteristics of this organism, and the diagnosis and treatment of this infection.     

All empires fall,you just have to know where to push: Antecedent issues for a study of learning difficulties in Australia

Abstract

A subset of the corpus of gifted students who have learning difficulties are those who have specific literacy disabilities; gifted literacy disabled (GLitD) students. Estimates suggest that approximately 10 per cent gifted read at a level of two or more years below their expected grade level. Surprisingly then, these students have attracted comparatively little past research interest.

The present investigation examined the reading characteristics of a group of 37 primary level GLitD students aged between 78 and 121 months. These students displayed a discrepancy in literacy perfor‐mance of at least 1 standard deviation below the mean for their chronological age in at least one of reading prose accuracy, prose reading com‐prehension or isolated word reading accuracy. As well, their spelling and phonemic awareness (segmentation and blending) were assessed. Scores on the cognitive factors of the W1SC‐III identified two groups: a group of 20 students with superior performance (at least 130 points) on both Verbal Comprehension and Perceptual Organisation (the ‘superior VC + PO’ group) and a group of 17 students with superior performance only on Perceptual Organisation (the ‘superior PO’ group).

The two groups differed in the literacy patterns displayed. The superior PO group showed the greater level of difficulty, with all measures of literacy at least one standard deviation below their expected score. The superior VC + PO group showed lower performance on isolated word reading and spelling. They did not differ in phonemic awareness.

The literacy disability displayed by both groups is attributed to a specific preference for the use of global rather than analytic information processing strategies. This in turn influences phonemic awareness knowledge and consequently orthographic knowledge. The superior VC + PO group are more able to compensate for this cognitive disability.

The implications of this study for the diagnosis and instruction of GLitD students are discussed.
