Diversity among Spanish-speaking English language learners: profiles of early literacy skills in kindergarten

This study explored heterogeneity in literacy development among 2,300 Hispanic children receiving English as a Second Language (ESL) services at the start of kindergarten. Two research questions guided this work: (1) Do Spanish-speaking English language learners receiving ESL services in the fall of kindergarten demonstrate homogeneous early literacy skills, or are there distinct patterns of achievement across measures of phonological awareness, alphabet knowledge, and orthography? and (2) if there are distinct profiles, to what extent do they predict literacy achievement at the end of kindergarten and the beginning of first grade? Using cluster analysis, the authors identified four distinct literacy profiles derived from fall kindergarten measures of phonological awareness, alphabet knowledge, and phonetic spelling. These profiles were found to be associated with literacy outcomes in spring of kindergarten and fall of first grade. The two profiles that were associated with greater success on later measures of concept of word in text, letter sound knowledge, word reading, and spelling were the two that included stronger performance on orthographic skills (i.e., alphabet knowledge and phonetic spelling). These findings demonstrated that there is heterogeneity among Hispanic ESL students at kindergarten entry and suggested that literacy instruction must be differentiated from the very beginning in order to meet students’ individual needs. The findings also suggested that orthographic skills should be assessed and taught early on. While phonological awareness may be a necessary precursor to reading, phonological awareness in the absence of orthographic skills may not be sufficient.     

A Technology‐Enhanced Unit of Modeling Static Electricity: Integrating scientific explanations and everyday observations

What trajectories do students follow as they connect their observations of electrostatic phenomena to atomic‐level visualizations? We designed an electrostatics unit, using the knowledge integration framework to help students link observations and scientific ideas. We analyze how learners integrate ideas about charges, charged particles, energy, and observable events. We compare learning enactments in a typical school and a magnet school in the USA. We use pre‐tests, post‐tests, embedded notes, and delayed post‐tests to capture the trajectories of students’ knowledge integration. We analyze how visualizations help students grapple with abstract electrostatics concepts such as induction. We find that overall students gain more sophisticated ideas. They can interpret dynamic, interactive visualizations, and connect charge‐ and particle‐based explanations to interpret observable events. Students continue to have difficulty in applying the energy‐based explanation.     

Viewing Michigan’s digital future: results of a survey of educators’ use of digital video in the USA

Digital video is a growing and important presence in student learning. This paper reports the results of a survey of American educators in Michigan (n = 426) conducted in spring 2008. The survey included questions about educators’ attitudes toward the streaming and downloadable video services available to them in their schools. The survey results showed that educators mainly used digital video to introduce and to conclude learning experiences. These educators, who predominantly used the Web‐based unitedstreaming ^TM digital video service, relished the service’s content breadth, short clips and potential to foster instructional innovation. However, many survey respondents reported concerns about internet connection bandwidth, projection capabilities and lack of end‐user control over on‐demand download and manipulation. Educators viewed school‐level Information and Communications Technology policies, bandwidth capacity and lack of support personnel as the causes of these difficulties. Because little research has been done on the implementation of digital video services in US schools, the conclusions of this study may provide direction for educators, researchers and policy‐makers who use a variety of digital video platforms and services.     

Wild botanic gardens as valuable resources for innovative environmental education programmes in Latin America

Wild botanic gardens consist of natural or semi-natural land remnants immersed in large urban areas or botanic gardens, which are managed for purposes of biodiversity preservation and public recreation. In Latin America, they tend to be affected by budget limitations; however, they serve as valuable resources that permit the development of innovative environmental education programmes. Specifically, we are considering the appropriateness of implementing critical environmental education and socio-constructivist programmes. As for practical considerations, it is important to include diverse epistemologies, and therefore, strategies or procedures characteristic of science teaching, such as problem-based learning, together with other characteristics of social activism and popular education initiatives, such as assemblies or meetings, and others characteristic of more traditional and indigenous worldviews, such as celebrations of the earth. In this way, Latin American wild botanic gardens may play a role in constructing environmentally responsible societies and the nurturing of a culture of reflective inquiry.     

Attitudes and learning disabilities: A literature review for school psychologists

Most LD students spend the major part of the school day within the regular classroom. Research, however, supports the rejected status of these students. The purpose of this presentation is to: (a) review research pertaining to the feelings professionals and peers have about learning disabled students, and (b) review those factors that may be important for consideration when attempting to modify these perceptions. School psychologists should address the attitudinal issues with a knowledge and basic conceptualization of various strategies that may be utilized to initiate attitude modification programs.

‘Low income doesn't mean stupid and destined for failure': challenging the deficit discourse around students from low SES backgrounds in higher education

The discourse around students from low socio-economic backgrounds often adopts a deficit conception in which these students are seen as a ‘problem’ in higher education. In light of recent figures pointing to an increase in the number and proportion of these students participating in higher education [Pitman, T. 2014. “More Students in Higher ed, But it's no more Representative.” The Conversation 28: 1–4] and an absence of evidence to support deficit thinking, this deficit discourse requires re-examination. Qualitative data from 115 interviews carried out across 6 Australian universities as part of a national study reveal that, contrary to the conception of these students as a ‘problem’, students from low SES backgrounds demonstrate high levels of determination and academic skills and that they actively seek high standards in their studies. This paper critically examines deficit conceptions of these students, drawing on findings from qualitative interviews with 89 successful students from low SES backgrounds and 26 staff members recognised as exemplary in their provision of teaching and support of students from low SES backgrounds. Drawing on these findings, this paper challenges the deficit discourse and argues for a more affirmative and nuanced conception of students from low SES backgrounds.
