Nature of Science and Nature of Scientists

Science & Education - The past decade has seen multiple debates and discussions over the appropriate framing of Nature of Science (NOS) for science education. These debates have stemmed from a...     

Understanding cellular respiration: An analysis of conceptual change in college biology

This study explored and documented the frequencies of conceptual difficulties confronted by college students seeking to understand the basic processes of cellular respiration. Using concept maps, clinical interviews and an open-ended instrument, viewpoints were elicited from 100 (novice) introductory biology students before and after relevant instruction in cellular respiration and from 100 (experienced) students enrolled in advanced biology courses. Chi-square analyses revealed significant differences among groups in the frequencies of scientifically acceptable and alternative conceptions. The findings suggest that novices harbor a wide range of conceptual difficulties that constrain their understanding of cellular respiration. Furthermore, many of these difficulties persist after instruction and new ones arise. Often these conceptual problems remain intact among experienced students despite well-planned, repeated instruction at advanced levels.     

Thematic patterns in children's writing: Human behavior evoking personal meaning

Conclusions Observing young writers and emergent writing behavior is necessary in order to gather information on the child's processes of writing and constructing meaning. It is through the powerful process of writing that children—in fact, all human beings—can learn more about themselves and the world around them: When he was five and a half years old Paul wrote and posted this sign over his workbench desk: DO NAT DSTRB GNYS AT WRK. The GNYS (genius) at work is our human capacity for language. DO NAT DSTRB is a caution to observe how it works, for the logic by which we teach is not always the logic by which childrent learn. (Bissex, 1980, p. 199) Writing allows children to discover meaning, entertainment, or power; writing is composing the self as well as composing written language. An analysis of thematic patterns in children's writing suggests the power of writing as just one road to becoming oneself. Previously, she was a kindergarten and primary grades teacher for ten years.

Reading comprehension,working memory and higher-level language skills in children with SLI and/or dyslexia

This study examined (1) whether working memory and higher-level languages skills—inferencing and comprehension monitoring—accounted for individual differences among Chinese children in Chinese reading comprehension, after controlling for age, Chinese word reading and oral language skills, and (2) whether children with specific language impairment (SLI) or dyslexia showed deficits in these skills. Eighty-two Cantonese Chinese-speaking children between the age of 7; 8–9; 5 were assessed. Regression analyses on the full sample offered support for the first question. The children were also classified into four groups: Typically-developing (TD; N = 34), specific language impairment-only (SLI-only; N = 18), SLI-dyslexia comorbid (SLI-D; N = 22) and dyslexia-only (D-only; N = 8). Pair-wise comparisons focusing on the second question revealed that both the SLI-only and the D-only group performed worse than the TD group in reading comprehension after controlling for age and nonverbal intelligence. The SLI-only and the D-only group showed a different profile of deficits: only the SLI-only group performed worse than the TD group in working memory, comprehension monitoring, and inferencing. The SLI-D comorbid group did worse than the SLI-only, but not the D-only group, in reading comprehension. The SLI-D comorbid group did not do worse than either single diagnosis group in the higher-level language skills associated with reading comprehension. These findings suggested adopting different intervention approaches for reading comprehension difficulties in children with SLI versus children with dyslexia.     

Making visible the literacy practices of elders through the day in the life methodology: considerations for literacy education across the lifespan

This pilot study uses ‘day in the life' methodology to observe the everyday literacy practices of a self‐identified thriving elder. Through the case of one nonagenarian female residing in an assisted living community in the United States, we identified the multimodal, posthuman nature of this elder's literacies, exploring how they were connected to a sense of well‐being and the types of literacies that remain relevant across the lifespan. We further consider what the insights gained from such a study might teach about literacy education more generally. We advocate for education that keeps open people's literacy options across the lifespan through acknowledging and cultivating the myriad interrelated constituents of literacies, including the physical, social and political.     

Can massive communities of teachers facilitate collaborative reflection? Fractal design as a possible answer

This paper explores the possibility that virtual communities of teachers with large numbers of members (referred to as massive communities of teachers) can offer support to novice teachers by means of collaborative reflection. The paper examines and conceptualises some problems found in professional massive communities and proposes that massification can dilute what some authors have called social presence or engagement. It is argued that this dilution, among other problems, very much hinders collaborative reflection among members of the community. Collaborative reflection is argued to be a crucial part of the support that novice teachers need in their first years in the profession. Therefore, a challenge is envisioned for massive communities of teachers to avoid the dilution of social presence or engagement. The authors argue that this dilution can be overcome by the use of multiple layers within a platform, referred to as fractal design.     

Including Emotional and Behavioural Difficulties Pupils in a Mainstream Comprehensive: A study of the behaviour of pupils and classes

A group of twelve pupils from an emotional and behavioural difficulties (EBD) school were transferred to a mainstream comprehensive school. They were supported by a specialist teacher and two Educational Support Assistants. The behaviour of the pupils was monitored. The behaviour of the EBD pupils was found to be very similar to that of the other pupils in the school. Only two of the EBD boys showed behaviour significantly worse than their peers. On the whole, the EBD pupils behaved extremely well in well-run classes, but their behaviour deteriorated in less well-organised lessons. Their behaviour tended to decline over the course of the school day, and the behaviour of all the pupils in the school was shown to be worse for the last period of the day. The implications of this research on the whole concept of EBD is discussed, as is the role, attitudes and practice of both teachers and educational psychologists.     

Home Literacy and Chinese Reading in Hong Kong Children

Measures of Chinese character recognition, vocabulary, and interest in reading were administered to 92 second grade children in Hong Kong, while questionnaires on parental literacy practices were administered to their parents. In a hierarchical regression equation, maternal education, children's age and vocabulary skill predicted 18% of the variance in reading, while home literacy practices and children's literacy self-efficacy predicted an additional unique 19% of the variance in Chinese reading skill. Results underscore the importance of some early home literacy practices for reading achievement, even among children who are already receiving formal literacy instruction.
