The aim of this study was to develop a model of students' energy concept development. Applying Case's (1985Case's ( , 1992 structural theory of cognitive development, we hypothesized that students' concept of energy undergoes a series of transitions, corresponding to systematic increases in working memory capacity. The US national sample from the Third International Mathematics and Science Study (TIMSS) database was used to test our hypothesis. Items relevant to the energy concept in the TIMSS test booklets for three populations were identified. Item difficulty from Rasch modeling was used to test the hypothesized developmental sequence, and percentage of students' correct responses was used to test the correspondence between students' age/grade level and level of the energy concepts. The analysis supported our hypothesized sequence of energy concept development and suggested mixed effects of maturation and schooling on energy concept development. Further, the results suggest that curriculum and instruction design take into consideration the developmental progression of students' concept of energy. ß

There is substantial evidence that Aboriginal youth face serious challenges in schooling, in general, and in literacy development, specifically. Thus, it is essential to design early literacy programmes that engage Aboriginal children and produce positive outcomes. In this article, the authors propose that such programmes include oral storytelling by teachers and students because it is a precursor to reading and writing across cultures and a traditional Aboriginal teaching tool. Moreover, storytelling fits with Aboriginal epistemology-the nature of their knowledge, its foundations, scope, and validity. The authors begin by reviewing a representative sample of the research that has examined the outcomes of early literacy instruction with Aboriginal children. Next, the authors describe Aboriginal epistemology, highlighting the role of the oral tradition. Finally, the authors describe an ongoing study aimed at supporting early literacy development through a developmentally and culturally appropriate oral storytelling instruction programme.

Mount Royal CollegeNarrative understanding has been identified as a primary mode of human thought that informs us about the nature, causes, and consequences of human actions and interactions and, as such, underlies social knowledge. The development of narrative thought was investigated by analyzing the structural complexity and social-psychological understanding displayed in the story compositions of 151 adolescents aged 10 to 18 years. A clear developmental progression was observed in structural complexity in terms of plot structure and the construction of flashbacks. Also observed was a clear developmental trend in social-psychological content from an intentional understanding of human behavior in terms of immediate feelings, thoughts, and goals to an interpretive understanding in terms of personal history, long-standing psychological traits, and broader contextual factors. Gender differences were also noted, with girls outperforming boys on some measures.

Research has determined that dual language books have a positive effect on literacy achievement, motivation, and family involvement in children’s schooling. In this study we used quantitative methods to complement the largely qualitative extant research. We analyzed the early literacy skills of 105 kindergarten children (45 comparison, 60 treatment) with diverse language backgrounds (35% English, 31% Punjabi, 16% Urdu, 18% other languages) from eight kindergarten classes in four suburban Canadian schools. Statistical analyses indicated that children who were read to using dual language books, written in French, Punjabi, and Urdu, demonstrated significantly greater gains in graphophonemic knowledge than children who were read to in English only. This gain occurred specifically in children who spoke the targeted languages at home; children who did not speak the targeted languages were not negatively affected. Findings are discussed in terms of developing metalinguistic awareness and directions for practice and research are discussed.

The effectiveness of dual-language book reading in culturally and linguistically diverse classrooms is largely uncontested. Yet there are repeated calls for more research to determine how this resource can be used more broadly and effectively by teachers, especially in emergent-literacy learning contexts. In the present study we analysed culturally and linguistically responsive teaching and learning in dual-language book reading vignettes to demonstrate how teachers and volunteer readers build on linguistic and cultural repertoires of emergent-literacy learners to help them gain metalinguistic awareness, cultural empowerment and identities as capable learners. We argue that diversity can be embraced and multilingualism can be positioned as normal by using dual-language books to motivate discussion about language and cultural artefacts. The findings suggest a rethinking of classroom practices based on family involvement in the classroom and a subtle shift in the balance of authority and expertise among teachers, children and families.
