Using Blogging in Support of Teacher Professional Identity Development: A Case Study

This case study explores the affordances a weblog (blog) offered to “Ms. Frizzle,” an urban middle school science teacher and exceptional blogger, to support her professional identity development. The 316 posts she wrote over 1 school year were systematically analyzed and triangulated with data from e-mail exchanges and interviews with Ms. Frizzle and her colleagues. Ms. Frizzle used her blog to tell stories of herself and her classroom, reflect on her practice, work through dilemmas, solicit feedback, and display competence, among other things. By doing so, she was able to wrestle with many issues that are central to the practice of urban science teaching and be recognized by herself and others as a “reform-minded” teacher committed to excellence and equity in education. To realize these benefits, however, Ms. Frizzle invested significant time and energy into her blogging and made certain uses of blogging features. Thus, although this study empirically supports the potential of blogging for teachers' professional identity development, it also indicates that the way in which teachers use blogging will determine the extent of the benefits they can derive from this practice.     

Publicizing Female Athletes' Weights: Implications for Female Psychology Undergraduates Acting as Spectators

Abstract

This investigation was conducted in order to determine if there were differences in the degree to which accuracy in throwing with the nonpreferred hand was developed when practice with projectiles of varying weights was used during the learning period. The effects of transfer of learning from the throwing of a ball of one weight to performance with a ball of another weight was also studied. The result indicated that practice with a light ball was as effective as practice with a heavier ball in developing skill to throw a heavier ball. Practice with the heavier ball when transferred to the lighter ball did not demonstrate a corresponding effect.

Maternal Attitudes and Knowledge of Child-Rearing: Associations with Family and Child Outcomes

A prospective, longitudinal study of a low birthweight, preterm cohort examined the effects of maternal knowledge of child development and concepts of child rearing on the quality of home environment and on child cognitive and behavioral outcomes. Measures of maternal knowledge at 12 months were found to be significantly associated with the quality of the home environment, the number of child behavior problems, and to a small but significant extent child Stanford-Binet IQ at 36 months. Maternal characteristics were associated with both maternal knowledge and maternal behavior. Child characteristics, including birthweight, were not associated with maternal knowledge or concepts of development for most of the cohort. Subgroup analyses by race/ethnicity revealed a similar pattern of results. However, a measure of neonatal health status was shown to be significantly associated with cognitive outcome in the African-American subgroup at 24 and 36 months.     

Understanding Asian American women's pathways to school leadership

Little is known about Asian American women administrators in the public schools. The study sought to understand the pathways of Asian American women to school leadership. In-depth interviews and researcher reflective memos were the primary data sources. The participants included 15 Asian American female school administrators in two states. We found that the women's career trajectories were similar yet unique; they were manifestation of the women's intersected experiences of gender, race–ethnicity, and age, situated in particular time and place. Often than not, the women had to negotiate their leadership aspiration and advancement through raced and gendered expectations. Others' encouragement and mentoring were instrumental for the women's development of self-knowledge and demystification of the leadership process. Most women taught at least 10–15 years before entering leadership. The women of earlier generations had far less career mobility and slim, if not absent, mentoring opportunities.     

A pilot evaluation of the social validity of a bullying bystander program adapted for high school students

Although school‐based programs are effective at decreasing bullying, the majority of studies have been conducted with elementary and middle school students. We conducted a pilot study using a randomized controlled design investigating the social validity of a brief, bullying bystander program adapted to be age‐appropriate for high school students (N = 65). Results indicated that high school students in the intervention group perceived the program to be acceptable and relevant and reported greater increases in knowledge ( = 0.27) and confidence to intervene ( = 0.27) in bullying situations compared to students in the control group. Despite being trained in the use of four intervention strategies, students reported using two of the strategies infrequently. Additionally, we found a significant difference between the intervention and control group for only one strategy (Φ = ?0.44). This study provides partial support for the social validity of the adapted program. Implications for implementing the program at the high school level are discussed.     

Field emission from Si tips coated with nanocrystalline diamond films

1. Introduction Recently, carbon nanotubes have attracted a lot of interest because of their outstanding electrical properties and their potential application as a possible material for fabrication of cold cathodes [1-3]. It was found that the field enhancement from carbon nano-tubes exhibited large local field enhancement and considerable field emission currents at relatively low applied voltage. Carbon nanotube-based field emission displays have been fabricated using well-aligned nano-tubes …     

Anti-periodic traveling wave solution to a forced two-dimensional generalized KdV-Burgers equation

1. Introducton The two-dimensional KdV equation was first derived by Kadomtsev and Petviashvili in 1970 [1], and it is also referred to as the KP equation. Periodic Traveling wave solutions to the KP and modified KP equation were investigated by Chen and Wen [2]. The author considers the generalized inhomogeneous two-dimensional KdV-Burgers equation as follows. {}[()] 0,,,0,txxxxxxxyyufuuuugxytabd+++++=纬% (1.1) where f C2(); b, d and a are given constant…     

Damage assessment of a continuous beam bridge based on the strain mode

1. Introduction In the structural damage identification, the confirmation of parameters sensitive to damage is the foremost, namely to decide what parameters are to be adopted, the next is to distinguish damaged from undamaged, and to determine the position and severity of damages. For local damage, an identifying parameter should be a local quantity and accord the following 4 basic conditions: 1) it is sensitive to local damages and is a monotone function depicting the severity of structural …
