Typical assessment systems often measure isolated ideas rather than the coherent understanding valued in current science classrooms. Such assessments may motivate students to memorize, rather than to use new ideas to solve complex problems. To meet the requirements of the Next Generation Science Standards, instruction needs to emphasize sustained investigations, and assessments need to create a detailed picture of students’ conceptual understanding and reasoning processes.

This article describes the design process and potential for automated scoring of 2 forms of inquiry assessment: Energy Stories and MySystem. To design these assessments, we formed a partnership of teachers, discipline experts, researchers, technologists, and psychometricians to align curriculum, assessments, and rubrics. We illustrate how these items document middle school students’ reasoning about energy flow in life science. We used evidence from review by science teachers and experts in the discipline; classroom experiments; and psychometric analysis to validate the assessments, rubrics, and automated scoring.  相似文献

Workplaces are settings where power, knowledge and self are brought together in a complex social environment which includes various forms of struggle related to identity, agency, socio-cultural norms, political structures and functional practices. The purpose of this article is to uncover how formal and informal work-related learning processes influence the identity transformation of workers with low literacy and essential skills. Drawing on two recent Canadian data bases which serve as cases in this study, the position taken by the authors is that the organisational context can both facilitate and impede worker subjectivity. Various conditions, approaches to learning and training pathways are examined as they contribute to social cognitive and transformative learning theories.  相似文献

Using the translated contents of the National Institute on Aging (NIA)'s Aging IQ, an educational intervention was delivered to older Korean Americans. The educational program was delivered via two different modalities, Internet-based education (n = 12) and in-class education (n = 11), and the overall feasibility and efficacy were evaluated by the Reach, Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework. A high level of completion and overall satisfaction with the program was observed in both groups. Both groups also exhibited a significant improvement in their knowledge about aging after the completion of the educational program. However, at the one-month follow-up, the Internet-based group showed a greater retention of the knowledge gained. The findings not only support the value of education on aging for older ethnic minorities but also suggest the use of the Internet as an integral modality of intervention delivery.  相似文献

Transactional distance has been defined as barriers to students’ engagement with learning in the online environment. This research updates Zhang’s (2003) scale of transactional distance, which quantified the extent of the barriers, in light of the massive changes in today’s web-based learning environment. The resulting revised scale of transactional distance (RSTD) is a parsimonious version with 12 elements (compared to 31 original) that measure the transactional distance between student and teacher, student and student, and student and content. The RSTD has excellent factorial validity and reliability, yields better fit statistics, and is easier and less time-consuming to apply. The transactional distance values are unique predictors of student satisfaction, which is correlated to learning and persistence (a major concern with massive open online courses). This information can form the basis for a systematic approach to improving the design of today’s contemporary open, flexible, distance education courses and thus serve as a valuable tool for researchers and educators alike.  相似文献

The effect of technology-enhanced learning (TEL) strategies in higher education has arguably been transformative despite the not-insignificant barriers existing in this context. Throughout the discourse very little attention has been paid to those primarily responsible for this implementation—academic teaching staff. This paper aims to highlight the impact of academic workload allocations, an often silent barrier to the uptake of TEL strategies in higher education. We will discuss the effects of academic identity and culture, preferential time allocation to associative activities, academic technological capacity, university policies and workload and funding models on the uptake, and implementation on TEL in higher education. Our aim is to highlight the risks to staff, students and institutions should these concerns not be addressed and to propose a model for utilisation by all staff responsible for implementing flexible workload models supportive of further implementation of TEL strategies across the sector.  相似文献

In this article, different inspection models are compared in terms of their impact on school improvement and the mechanisms each of these models generates to have such an impact. Our theoretical framework was drawn from the programme theories of six countries’ school inspection systems (i.e. the Netherlands, England, Sweden, Ireland, the province of Styria in Austria and the Czech Republic). We describe how inspection models differ in the scheduling and frequency of visits (using a differentiated or cyclical approach), the evaluation of process and/or output standards, and the consequences of visits, and how these models lead to school improvement through the setting of expectations, the use of performance feedback and actions of the school's stakeholders. These assumptions were tested by means of a survey of principals in primary and secondary schools in these countries (n?=?2239). The data analysis followed a three-step approach: (1) confirmatory factor analyses, (2) path modelling and (3) fitting of multiple-indicator multiple-cause models. The results indicate that Inspectorates of Education that use a differentiated model (in addition to regular visits), in which they evaluate both educational practices and outcomes of schools and publicly report inspection findings of individual schools, are the most effective. These changes seem to be mediated by improvements in the schools’ self-evaluations and the schools' stakeholders’ awareness of the findings in the public inspection reports. However, differentiated inspections also lead to unintended consequences as principals report on narrowing the curriculum and on discouraging teachers from experimenting with new teaching methods.  相似文献
