Impacts of contextual and explicit instruction on preservice elementary teachers' understandings of the nature of science

This mixed‐methods investigation compared the relative impacts of instructional approach and context of nature of science instruction on preservice elementary teachers' understandings. The sample consisted of 75 preservice teachers enrolled in four sections of an elementary science methods course. Independent variables included instructional approach to teaching nature of science (implicit vs. explicit) and the context of nature of science instruction (as a stand‐alone topic vs. situated within instruction about global climate change and global warming). These treatments were randomly applied to the four class sections along a 2 × 2 matrix, permitting the comparison of outcomes for each independent variable separately and in combination to those of a control group. Data collection spanned the semester‐long course and included written responses to pre‐ and post‐treatment administrations of the VNOS‐B, semi‐structured interviews, and a variety of classroom artifacts. Qualitative methods were used to analyze the data with the goal of constructing profiles of participants' understandings of the nature of science and of global climate change /global warming (GCC/GW). These profiles were compared across treatments using non‐parametric statistics to assess the relative effectiveness of the four instructional approaches. Results indicated that preservice teachers who experienced explicit instruction about the nature of science made statistically significant gains in their views of nature of science regardless of whether the nature of science instruction was situated within the context of GCC/GW or as a stand‐alone topic. Further, the participants who experienced explicit nature of science instruction as a stand‐alone topic were able to apply their understandings of nature of science appropriately to novel situations and issues. We address the implications of these results for teaching the nature of science in teacher preparation courses. © 2010 Wiley Periodicals, Inc., Inc. J Res Sci Teach 48: 414–436, 2011     

Do students’ beliefs about knowledge and knowing predict their judgement of texts’ trustworthiness?

We examined whether epistemic beliefs predict students’ evaluation of documents. Undergraduates read two texts on climate change. Participants judged the trustworthiness of each text and then indicated the criteria for their rating. We found that readers who believe strongly in relying on personal interpretations rather than on authorities trusted both documents less and used the document’s content or their own opinion as criteria for judging trustworthiness. We also found that readers who believe that knowledge claims should be critically evaluated through logic and rules rated the science text as more trustworthy and used the criteria of their own opinion, author and content more than readers who believe in relying on their own experiences. These effects hold true while controlling for readers’ prior knowledge and text comprehensibility.     

An analysis of associations between residential and school mobility and educational outcomes in South African urban children: The Birth to Twenty cohort

Using data from Birth to Twenty, a cohort of South African urban children, the current paper investigates the relationships between residential and school mobility and a set of educational outcomes. The findings provide some evidence of a positive association between changes in residence and numeracy and literacy scores, and school mobility was found to be associated with grade repetition, however, no relationship was observed between changes in school and competency in numeracy and literacy. The South African study provides a counter example to trends observed in higher-income countries, while highlighting that associations are likely to be context specific.     

Bridging the gap: a longitudinal study of the relationship between pedagogical continuity and early Chinese literacy acquisition

This longitudinal study examined the relationship between pedagogical continuity in literacy education and early literacy development by comparing Chinese children in Hong Kong and Shenzhen. Stratified random sampling was used to select 24 preschool and Primary 1 classes in four communities catering to middle‐class families in each city. The 24 teachers were interviewed about their teaching methods and views on pedagogical continuity in individual sessions. Further, their teaching activities were videotaped over a period of a week. Their students (n = 758) completed a Chinese literacy attainment test at the beginning and at the end of the same academic year. Analyses indicated that Hong Kong students outperformed their Shenzhen counterparts in Chinese literacy attainment, at both preschool and primary levels, concurrently and longitudinally. This suggests that the holistic approach followed in Hong Kong might have a more positive impact on children's literacy development than the approach followed in Shenzhen. Implications of the findings for early childhood curriculum reform are discussed.     

‘They didn’t tell me anything’: women’s literacies and resistance in rural Mexico

Drawing from ethnographic case studies, this article considers issues of women’s access to education by exploring the literacy experiences of four women in rural Mexico. Ironically, as physical access to education in this area has increased, women’s literacy experiences have become more complex, rather than more libratory. Formal literacy, as it plays out for women in this community, is experienced as both an oppressive force as well as a tool for resistance to other forms of oppression. More importantly, the stories in this article highlight the socially dynamic nature of literacy as these four women utilise interpersonal relationships in order to subvert oppressive norms. These findings have implications both for theories of literacy as well as for educators who wish to work in more engaged ways with women and their children who emigrate from areas like rural Mexico.

Speech development patterns and phonological awareness in preschool children

To examine the association between speech production and early literacy skills, this study of 102 preschool children looked at phonological awareness in relation to whether children were delayed, typical, or advanced in their articulation of consonants. Using a developmental typology inspired by some of the literature on speech development (Kahn and Lewis, The Kahn-Lewis phonological analysis, 1986; Shriberg, Journal of Speech and Hearing Research 36(1):105-140, 1993a), we found that failure to master the early-8 consonants and a greater prevalence of certain types of production errors were associated with deficient phonological awareness. We also found that children who made no consonant errors had advanced phonological awareness relative to other children in the sample. In all cases, both productive speech patterns and speech errors were more closely linked with rhyme awareness than with phoneme awareness. The association between speech production and rhyme awareness may provide some new directions for the early preschool assessment of risk for reading problems.     

Assessing preschoolers’ emergent literacy skills in English and Spanish with the Get Ready to Read! screening tool

This study investigated the ability of the English and Spanish versions of the Get Ready to Read! Screener (E-GRTR and S-GRTR) administered at the beginning of the preschool year to predict the oral language and phonological and print processing skills of Spanish-speaking English-language learners (ELLs) and English-only speaking children (EO) at the end of the year. The results revealed that the E-GRTR predicted the EO and ELL children’s English emergent literacy skills and the ELL children’s Spanish emergent literacy skills, and the S-GRTR predicted the ELL children’s English and Spanish emergent literacy skills. For both groups, the E-GRTR and the S-GRTR were better at predicting children’s print knowledge in English and Spanish compared to the other emergent literacy measures. The findings suggest that both screeners can be used effectively to assess preschool children’s emergent literacy skills.
