This article reports findings on growth in 3 science teachers' expertise with interpretation of student work over 1 year of participation in a program. The program was designed to strengthen classroom assessment. Using a framework for classroom assessment expertise, we analyze patterns of teacher learning, and the roles of the professional program and the quality of the assessments provided with teachers' instructional materials. 相似文献

This report provides evidence of the influence of professional development and curriculum on upper elementary students' understandings
of fractions. Three groups of teachers and their students participated. Two groups implemented a fractions unit that emphasized
problem solving and conceptual understanding. The Integrated Mathematics Assessment (IMA) group participated in a program
designed to enhance teachers' understandings of fractions, students' thinking, and students' motivation. The Collegial Support
(SUPP) group met regularly to discuss strategies for implementing the curriculum. Teachers in the third group (TRAD) valued
and used textbooks and received no professional development support. Contrasts of student adjusted posttest scores revealed
group differences on two scales. On the conceptual scale, IMA classrooms achieved greater adjusted posttest scores than the
other two groups, with no differences between SUPP and TRAD groups. On the computation scale, contrasts revealed no differences
between IMA and TRAD, although TRAD achieved greater adjusted scores than SUPP (p < 0.10). Our findings indicate that the benefits of reform curriculum for students may depend upon integrated professional
development, one form exemplified by the IMA program.

Understanding the particulate nature of matter (PNM) is vital for participating in many areas of science. We assessed 11 students’ atomic/molecular‐level explanations of real‐world phenomena after their participation in a modelling‐based PNM unit. All 11 students offered a scientifically acceptable model regarding atomic/molecular behaviour in non‐heated solids. Yet, 10 of 11 students expressed the view that, in response to added heat energy, atoms/molecules in a solid increase in movement to a degree beyond what is scientifically accepted. These students attributed a gas‐like model of atomic/molecular movement to situations involving a heated solid. Of the students who held two conflicting models of atomic/molecular movement in solids, almost all provided justification for doing so, indicating their holding of the conflicting models was unproblematic. These findings can be interpreted to mean that students may drop constraints of certain scientific representations and apply, assess, or revise models when explaining unfamiliar phenomena. In fact, we believe students may develop conflicting causal models as a result of misperceptions they acquire, in part, during classroom instruction regarding atomic/molecular movement. However, our findings may also be interpreted as an incidence of student model development that may later aid their understanding of a more complex model, one that involves substantial sub‐atomic electron movement to account for heat transfer in solids. Whether or not this is the case remains to be seen. Implications for student learning and instruction are discussed. 相似文献

ABSTRACTThe community college sector of higher education has, over the past 20 years, become highly engaged in fundraising. Typically relying on business and industry sponsorships, institutional leaders have begun to shift their development strategies to focus increasingly on individuals who have the capacity and disposition to support the work of their colleges. Crowdsourcing is a relatively new process for garnering the interest and timely collection of interests and moving them toward the action of financially supporting an institution. This study explored how crowdsourcing is being used by community colleges, what institutional leaders expect from the process, and how these funds are used. Study findings revealed that crowdsourcing is used primarily to raise gifts for immediate expenditure, to identify potential long-term donors, and to electronically engage persons who have an interest in the welfare of the college. 相似文献

Standpoint: Disappearing authors: A postmodern perspective on the practice of writing for the screen
The current study examined content-specific relationships of citizens' use of city Web sites with civic engagement. A Web-based, volunteer survey of 1,966 citizen users of city Web sites found that surveillance, practical services, and direct democracy features functioned as important conditions for citizens' real-world civic engagement. Results indicated that citizens' use of practical services and direct democracy features of city Web sites were associated with citizens' civic involvement and political behaviors. The findings suggest that the relationships between citizens' use of city Web sites and civic engagement differ according to the purpose for which citizens use the sites. The results of the current study exhibit an indication that city Web sites can promote civic engagement among citizens. 相似文献

This study helps bridge the existing divide between the knowledge on health news reporting in mainstream mass media and health reporting in media outlets serving Native American populations in the United States. The current work presents the first survey of journalists working in Native-serving media outlets to identify role conceptions, perceived importance, and actual practices of health reporting. Aided in data collection by the Native American Journalists Association, findings indicate journalists (N?=?100) place a high value on their role as disseminators of culturally relevant health information. However, results conflict in regard to the prioritization of health news reporting. Although journalists recognize health news should be a top priority, they point to a general lack of will from news leadership to make it an organizational priority. Additionally, results show that although journalists have comfort and confidence in health-related reporting, access to qualified sources remains an area for opportunity. 相似文献
