Accountability-oriented reforms demand immediate and continual gains on achievement test, for all students, and without diminishing other outcomes or undermining instruction. This paper describes a framework for aligning classroom assessment and external testing with the aim of negotiating these seemingly contradictory goals. The framework varies the sensitivity to instruction and the representations of knowledge across approaches to assessment. Cycles of design- based studies successively refine relationships between a curriculum and the frame that each assessment provides. Doing so, we argue, leverages the unique formative and summative balance across assessments in order to scaffold learning and demonstrate the “consequential” validity of our strategy without compromising curricula, instruction, or the “evidential” validity that warrants their continued use. 相似文献

In this paper we describe our research using a multi-user virtual environment, Quest Atlantis, to embed fourth grade students in an aquatic habitat simulation. Specifically targeted towards engaging students in a rich
inquiry investigation, we layered a socio-scientific narrative and an interactive rule set into a multi-user virtual environment
gaming engine to establish a virtual world through which students learned about science inquiry, water quality concepts, and
the challenges in balancing scientific and socio-economic factors. Overall, students were clearly engaged, participated in
rich scientific discourse, submitted quality work, and learned science content. Further, through participation in this narrative,
students developed a rich perceptual, conceptual, and ethical understanding of science. This study suggests that multi-user
virtual worlds can be effectively leveraged to support academic content learning. 相似文献

This study details an innovative approach to coordinating and enhancing multiple levels of assessment and discursive feedback around an existing multi‐media curricular environment called Astronomy Village®. As part of a broader design‐based research programme, the study analysed small group interactions in feedback activities across two design cycles. The goal of this analysis is to develop an understanding of the ways that a situative approach to assessment and practise supports learning. Findings demonstrate ways that student and teacher engagement in collaborative activities support and constrain meaningful understanding, which we consider in terms of a trajectory of participation in and across conversations and written assessments, as well as individual learning gains on formal classroom examinations and standards‐oriented external tests. Analyses of complementary formulations of domain concepts—discourse practises and assessment performance—suggest that participation in social forms of scientific engagement supports both learning and subsequent performance in more formal contexts. We suggest design principles for integrating the formative functions of discursive feedback with the summative functions of traditional assessment, through participation in different forms of science discourse(s). 相似文献

Evaluating the impact of instructional innovations and coordinating instruction, assessment, and testing present complex tensions. Many evaluation and coordination efforts aim to address these tensions by using the coherence provided by modern cognitive science perspectives on domain-specific learning. This paper introduces an alternative framework that uses emerging situative assessment perspectives to align learning across increasingly formal levels of educational practice. This framework emerged from 2 design studies of a 20-hr high school genetics curriculum that used the GenScope computer-based modeling software. The 1st study aligned learning across (a) the contextualized enactment of inquiry-oriented activities in GenScope, (b) “feedback conversations” around informal embedded assessments, and (c) a formal performance assessment; the 2nd study extended this alignment to a conventional achievement test. Design-based refinements ultimately delivered gains of nearly 2 SD on the performance assessment and more than 1 SD in achievement. These compared to gains of 0.25 and 0.50 SD, respectively, in well-matched comparison classrooms. General and specific assessment design principles for aligning instruction, assessment, and testing and for evaluating instructional innovations are presented. 相似文献

As an example of design-based research, this study refined an assessment strategy for simultaneously enhancing inquiry-based learning and supporting achievement on conventional assessment measures. Astronomy Village ® : Investigating the Universe? is a software program designed to engage secondary science students in authentic and inquiry-based learning over core topics in astronomy. The software was enhanced with a 20-hour curriculum and three levels of assessment to ensure successful inquiry experiences and high-stakes achievement. The first year implementation of Astronomy Village® yielded significant gains on a curriculum-oriented exam but not a standards-oriented test, and provided useful design insights that were integrated into the second year implementations. Significant gains were obtained on the test during the second year as well. It is expected that many existing inquiry-oriented science curricula might be similarly enhanced, and is suggested that a large-scale effort to do so might have a lasting impact on science education. 相似文献

This design-based research study considers the learner-generated design and refinement of a school garden. We report one enactment of the Connected Gardening project in order to illuminate and understand how a fourth-grade class organizes and refines its garden plot using observations of the physical environment and evaluations of data from a networked digital probe. By examining the ways individuals, materials, and activities influence, and are influenced by, one another, our qualitative analysis characterizes interplay among an ecosystem, a garden and graphical representations of environmental indicators in real time and over time. We consider the novel affordances of such a cyber-physical systems for supporting participatory culture within yet beyond school classrooms. 相似文献

This study examines the design and enactment of a secondary physics unit on electromagnetism. The unit used an educational videogame to support peer dialogic engagement in a Singapore secondary school by engaging learners with qualitative physics phenomena. As an example of game-based learning, the unit includes activities and resources that organize a recurring progression of playing and interacting around science that we term play-centered cycles. We incorporate two complementary, qualitative analyses to consider how a recurring progression of playing with and talking about science-mediated peer dialogic engagement across two separate classes. Findings demonstrate that peer dialogic engagement occurred within each play-centered cycle for both classes but that the nature of such engagement varied across cycles and student teams. Additionally, comparative case analyses of focal teams’ peer dialogic engagement illuminate how the design of play-centered cycles productively supported play and learning while also highlighting emerging tensions for sustaining dialogic engagement. Findings underscore the plausibility of this approach to fostering science learning by articulating two principles for designing science learning environments that can guide ongoing efforts to enlist videogames and play in the service of talking about and learning science.
