The perceived impacts of e-government on U.S. cities: A survey of Florida and Texas City managers

This study examines the perceived impacts of electronic government or e-government adoption on U.S. cities. This research conducted a survey of Texas and Florida city managers in the fall of 2005 to find out their opinions on the impact of e-government on their city government. The results indicated that e-government is having a positive impact on management, stakeholder involvement, needs and collaboration, and procurement in American cities. There are, however, concerns over spam or unsolicited e-mail and the ability of e-government to reduce the level of staffing. The results of this study imply that, according to city managers' perceptions, e-government adoption in American city governments is positively viewed as having an impact on their organizations and communities.

Cognitive and social help giving in online teaching: an exploratory study

While literature suggests that college students may be less reluctant to seek help in online rather than traditional courses, little is known about how online instructors give help in ways that lead to increased student help seeking and academic success. In this study, we used theories and research on learning assistance and scaffolding, teacher immediacy, social presence, and academic help seeking to explore through a cross-case study design how three online instructors differed in their use of cognitive and social supports and how those differences related to student perceptions of support, help seeking, and performance. Primary data sources included all course postings by the instructors, interviews with the instructors, observational field notes on course discussions, student interviews, and final student grades. Archived course documents and student discussion postings were secondary data sources. Data analysis revealed that while all instructors provided cognitive and social support, they varied in their level of questioning, use of direct instruction, support for task structuring, and attention to group dynamics. This variation in teaching presence related to differences across the courses in student perceptions of support, student help seeking in course discussions, and final course grades. Implications for online teaching and suggestions for further research are offered.

Investigating the role of bilingual teaching assistants in Hong Kong: an exploratory study

Background:?Recent government initiatives in Hong Kong have focused on raising the participation of students from South Asian backgrounds in mainstream schools, to encourage their further integration into Hong Kong's educational system and society. These students' learning in mainstream schools takes place within the context of the central curriculum and, thus, students face the challenge of learning Chinese as an additional language. Mainstream schools sometimes provide additional support, including the provision of bilingual teaching assistants to address the specific needs of the students from South Asian backgrounds.

Purpose:?This exploratory study aims to investigate the roles of bilingual teaching assistants in Hong Kong.

Method:?Interviews were held with two bilingual teaching assistants from the South Asian community in Hong Kong who were working in a mainstream secondary school. Teachers from the school were also interviewed. Open-ended interview questions focused on perceptions of the roles and responsibilities of bilingual teaching assistants in Chinese-language-medium classes. The data were analysed to identify any emergent patterns and themes.

Findings:?The research findings indicate that the bilingual teaching assistants from the South Asian community not only took on the role of helping the learners from South Asian backgrounds in Chinese language acquisition, but also acted as cultural mediators between mainstream school culture and the culture of the South Asian community in Hong Kong.

Conclusions:?This small-scale exploratory research study suggests the importance of the role of bilingual teaching assistants in promoting equal access to quality education for ethnic minorities in Hong Kong.
