Proportional Reasoning among 7th Grade Students with Different Curricular Experiences

Contextual problems involving rational numbers and proportional reasoning were presented to seventh grade students with different curricular experiences. There is strong evidence that students in reform curricula, who are encouraged to construct their own conceptual and procedural knowledge of proportionality through collaborative problem solving activities, perform better than students with more traditional, teacher-directed instructional experiences. Seventh grade students, especially those who study the new curricula, are capable of developing their own repertoire of sense-making tools to help them to produce creative solutions and explanations. This is demonstrated through analysis of solution strategies applied by students to a variety of rate problems.     

Ecological contexts and early learning: Contributions of child,family, and classroom factors during Head Start,to literacy and mathematics growth through first grade

The current study investigated the extent to which child, family, and classroom factors during Head Start are related to children's literacy and mathematics skills at the beginning of preschool and through first grade. Children and families (n = 945) were participating in the Family and Child Experiences Survey (FACES), a large-scale data collection effort that assessed children's developing skills as well as their family and classroom environments. Longitudinal growth models revealed that Head Start children began their academic careers well below their more advantaged peers in literacy and mathematics, although by the end of first grade, their scores were nearly on par with national averages. Demographic characteristics of children, as well as their early language and social skills, were the strongest predictors of children's initial status and growth in both early academic domains. Results highlight key foundations and specific promotive factors of early school success for the nation's most disadvantaged children.     

Deaf children and bullying: directions for future research

U.S. SCHOOLS are currently addressing bullying and its effects on children. Bullying is characterized as repetitive verbal teasing, threatening, physical intimidation, demeaning others, violent acts, torture, and other forms of verbal and physical aggression (Smith and Sharp, 1994a). Little is known about bullying and its impact on deaf children. Measures to describe and quantify bullying factors in this population should be developed and validated that address characteristics of deaf victims and bullies, various types of school settings deaf children attend, bullying dynamics that may be unique to this population and its peers, and other environmental factors. The presence of disabilities besides deafness, social support systems of deaf children and their families, sociocultural background, degree of hearing loss, parental educational levels and occupations, socioeconomic status, and linguistic backgrounds should also be considered. This discussion highlights issues and precautions concerning future directions for studying bullying with deaf children.     

Librarians in the Woods Hole Biomedical Informatics course

What has come to be known as the "Woods Hole course", Biomedical Informatics, is a week-long course sponsored by the National Library of Medicine which has been offered since 1992. Its participants include librarians, clinicians, educators, and administrators. This article discusses the content of the course and its applicability to medical librarians.     

How prior knowledge affects word identification and comprehension

While prior knowledge of a passage topic is known to facilitate comprehension, little is known about how it affects word identification. We examined oral reading errors in good and poor readers when reading a passage where they either had prior knowledge of the passage topic or did not. Children who had prior knowledge of the topic were matched on decoding skill to children who did not know the topic so that the groups differed only on knowledge of the passage topic. Prior knowledge of the passage topic was found to significantly increase fluency and reduce reading errors, especially errors based on graphic information, in poor readers. Two possible mechanisms of how prior knowledge might operate to facilitate word identification were evaluated using the pattern of error types, as was the relationship of errors to comprehension. Implications of knowledge effects for assessment and educational policy are discussed.     

Using a Wiki in a Scientist-Teacher Professional Learning Community: Impact on Teacher Perception Changes

In this study, a wiki was integrated into a professional development model that systemically addresses early-career teachers?? needs. This study was conducted to examine the impact of wiki-based professional development activities in a scientist-teacher professional learning community and focused on early-career teachers?? perceptions of the role of wiki technology and knowledge of teaching through inquiry. Teachers participated in the Professional Learning Community Model for Entry into Teaching Science (PLC-METS), a professional development program that is based on an integrated teacher education model of knowledge sharing, collaboration, and communication between teachers and scientists, with the goal of supporting early-career teachers?? ability to engage their students in scientific inquiry. The use of a wiki environment to collaborate on activities, deliver resources, and share knowledge is rapidly expanding in professional development communities. The use of the wiki in PLC-METS positively predicted the results of teachers?? knowledge of inquiry-based teaching. Results demonstrate that the wiki can contribute to building a learning community for collaboration between early-career science teachers and scientists. The paper also discusses the educational implications for the design of wiki-based professional learning communities that impact teachers?? professional development.
