As many primary pre-service teachers enter teacher education courses with little science background, it is essential in teacher education courses to provide opportunities for them to learn more science independently. The purpose of this study is to investigate an online pedagogical activity that fosters the social construction of science knowledge by primary pre-service teachers working in small virtual teams. The study investigated how the pre-service teachers collaborated online in virtual teams to complete set tasks, their attitudes toward and beliefs about the effectiveness of the online learning experience, and the types and quality of the resources developed. The findings indicated that the virtual team-produced science resource materials were generally of high quality, with nearly half the number of teams engaging with Web 2.0 technologies (e.g. wikis and blogs) to construct their product. The findings indicated positive attitudes toward the collaborative learning even though beliefs about online learning were mixed. 相似文献

The traditional focus of intergovernmental services research has been on technological development, not on user acceptance; yet user acceptance of intergovernmental services in each electronic government (e-Government) implementation affects the ultimate success of the e-Government project. In the e-Government implementation context, many governments have invested huge amounts of money and manpower to make intergovernmental services both available and user-accepted, although some individuals have no intention of using them. The electronic document management system (EDMS) is the most popular intergovernmental service in the e-Government project. Thus, e-Government researchers need to identify the factors that determine user acceptance of EDMS. 相似文献

The present study investigated the relationships between supervisee and supervisor trait emotional intelligence (EI) levels
and their perception of the supervisory working alliance. Data were collected from 64 supervisor-supervisee dyads among masters-level
community counseling internship students and their site supervisors. Findings indicated that supervisees and supervisors with
higher levels of trait EI tended to perceive the supervisory working alliance more positively. However, findings did not support
the presence of an interaction effect between supervisee and supervisor trait EI on either supervisees’ or supervisors’ perceptions
of the working alliance. Implications of the findings and directions for future research are discussed. 相似文献

This study adopted design and development research methodology (Richey & Klein, Design and development research: Methods, strategies, and issues, 2007) to systematically investigate the process of applying instructional design principles, human–computer interaction, and software
engineering to a performance support system (PSS) for behavior management in a classroom. The purpose was to examine how a
proposed instructional design framework based on Ausubel’s (The psychology of meaningful verbal learning, 1963) advance organizer theoretical approach could be used to address inherent problems of technically driven PSSs. Development
data were collected from a six-phase participatory rapid prototyping process using both qualitative and quantitative methods.
Findings indicated that (a) the advance organizer concept combined with a matrix design metaphor provided an effective way
to illustrate conceptual connections and relations among PSS modules and their elaborated information, (b) the system served
as a reference to support participants for exchanging ideas with other teachers as well as with parents of students, and (c)
the rapid prototyping process established parameters that helped the project team maintain a focus on users and collect data
useful for advancing to a higher phase of system development. Potential drawbacks pertaining to the proposed design strategies
and their possible corrective actions are also reported and discussed. 相似文献

Should I Stay or Should I Go? Examining the Career Choices of Alternatively Licensed Teachers in Urban Schools 总被引:1,自引:0,他引:1
In order to address the issue of persistent teacher shortages, urban districts increasingly rely on alternatively licensed
teachers who are often viewed as well-suited to work in urban areas because of their greater age, life and work experiences,
and understanding of diverse communities. Yet, research on the retention of these teachers remains inconclusive, with some
notable studies suggesting that alternatively licensed teachers are as likely as their traditionally prepared counterparts
to quit teaching or migrate out of urban school settings. In this study, we explore the process and salient considerations
of five alternatively licensed math and science teachers deciding whether or not to continue teaching in a Midwestern, urban
school district. Whereas previous studies typically examine teacher recruitment and retention issues through a narrow analysis
of labor market incentives and other external inducements, our study situates teachers’ career decisions within a more holistic
narrative that illustrates how individual actions are never determined by any single factor, but rather a web of simultaneous
and sometimes contradictory forces generated by prior expectations and immediate realities that are professional as well as
personal in nature. 相似文献

In this study,particle image velocimetry was applied to investigate flow fields of wormlike micelle(WLM) fluids in a mixing tank equipped with a four-blade,down-pumping,pitched blade turbine. First,the rheology of WLM fluids was investigated,and the Carreau model was utilized to describe their apparent viscosity. Then,the effects of the rotation speeds and rheological properties on the flow fields were studied using different WLM fluids at different rotation speeds. The results revealed that with increasing Reynolds number,the discharge angle decreases and the carven size increases. Furthermore,elastic effects of WLM fluids lead to a more curved flow and a smaller carven. 相似文献
