Background: Research on peer assessment has noted ambiguity among students in using peer assessment for improving their work. Previous research has explained this in terms of deficits in the student feedback, or differences in student views of what counts as high-quality work.
Purpose: This study frames peer assessment as a social process in the science classroom. The aim is to explore peer assessment in science education as social practice in order to contribute to an understanding of the affordances and constraints of using peer assessment as a learning tool in science education.
Design and Method: The study was conducted in four lower secondary school classes, school years 8 and 9, in two different schools. An intervention study was designed focussing on the topic of experimental design. It involved the students in a process of peer assessment where they designed experiments individually, and then exchanged their designs, conducted each other’s experiments, provided feedback to each other and revised their original design after discussing the feedback in groups. Data were collected in the form of audio recordings of student discussions and written work.
Results: The results show that, although not all peer feedback resulted in revisions, peer feedback was useful to the students in group interaction when negotiating quality in their work.
Conclusions: To conclude, the potential for using peer assessment in science education should not only be evaluated through the students’ revisions but also in terms of in what ways the feedback constitutes interactional resources for defining quality in student work. 相似文献
Implementing peer feedback in revisions is a complex process involving first planning to fix problems and then actual implementing feedback through revisions. Both phases are influenced by features of the peer feedback itself, but potentially in different ways, and yet prior research has not examined their separate role in planning or the mediating role of planning in the relationship of feedback features and implementation. We build on a process model to investigate whether feedback features had differing relationships to plans to ignore or act on feedback versus actual implementation of feedback in the revision, and whether planning mediated the relationship of feedback features and actual implementation. Source data consisted of peer feedback comments received, revision plans made, and revisions implemented by 125 US high school students given a shared writing assignment. Comments were coded for feedback features and implementation in the revision. Multiple regression analyses revealed that having a comment containing a specific solution or a general suggestion predicted revision plans whereas having a comment containing an explanation predicted actual implementation. Planning mediated the relationship to actual implementation for the two feedback features predicting plans, suggestion and solution. Implications for practice are discussed.
Designing and implementing online or digital learning material is a demanding task for teachers. This is even more the case when this material is used for more engaged forms of learning, such as inquiry learning. In this article, we give an informed account of Go-Lab, an ecosystem that supports teachers in creating Inquiry Learning Spaces (ILSs). These ILSs are built around STEM–related online laboratories. Within the Go-Lab ecosystem, teachers can combine these online laboratories with multimedia material and learning apps, which are small applications that support learners in their inquiry learning process. The Go-Lab ecosystem offers teachers ready–made structures, such as a standard inquiry cycle, alternative scenarios or complete ILSs that can be used as they are, but it also allows teachers to configure these structures to create personalized ILSs. For this article, we analyzed data on the design process and structure of 2414 ILSs that were (co)created by teachers and that our usage data suggest have been used in classrooms. Our data show that teachers prefer to start their design from empty templates instead of more domain–related elements, that the makeup of the design team (a single teacher, a group of collaborating teachers, or a mix of teachers and project members) influences key design process characteristics such as time spent designing the ILS and number of actions involved, that the characteristics of the resulting ILSs also depend on the type of design team and that ILSs that are openly shared (i.e., published in a public repository) have different characteristics than those that are kept private.
Creating public value is a key goal of public administrations, both in their daily business and in the growing field of smart government and smart cities, which focuses on IT-enabled innovations in the public sphere. However, many public administrations still struggle with such innovations due to complex technologies, high investments, and the numerous stakeholders involved. To address this issue, some local governments in continental Europe have turned to collaborative innovation approaches, partnering with (semi-)public utility companies in the hope that their additional innovation assets will boost innovativeness. Nevertheless, it remains unclear how exactly such collaborations should be governed to ensure that the focus remains on creating public value, as utility companies may have their own agendas. To explore this question, we conducted a comparative case study in the context of smart city initiatives with four cases in Swiss local governments. Drawing on agency and stewardship theory, we then propose a model of public-value-focused collaborative innovation, enabling us to explore various collaboration characteristics and their effects on public value creation. Our findings suggest that both agency- and stewardship-based collaborations increase innovativeness. However, while agency collaborations tend to produce smart city innovations that mainly serve the utility companies' business interests, stewardship relationships lead to innovations that are focused more on public value creation. As such, our study extends the literature on the effects of collaborative innovation on public value, and it provides practical recommendations on how such collaborative innovation should be designed. 相似文献
The mammalian hippocampus is certainly one of the best investigated brain regions. It fascinates neuroscientists particularly because of its important role in memory. The names for the various parts of the hippocampal formation were created in the course of the first thorough explorations of human brain anatomy. The present, internationally agreed terminology reflects an unfortunate muddle that has been going on for several hundred years. Not surprisingly, even today the origins of some of the names are not always given correctly. It is generally accepted that the Italian anatomist Arantius was the first to apply the term 'hippocampus' to part of that region in the human brain. To later authors, however, this name appeared more or less enigmatic and they proposed various other terms. Yet careful reading of the entire original text of Arantius leads to the conclusion that it was not the hippocampus in our modern terms but the dentate gyrus which he compared to a little sea horse or a silkworm. 相似文献
Cognitive load theory has been very influential in educational psychology during the last decade in providing guidelines for
instructional design. Whereas numerous empirical studies have used it as a theoretical framework, a closer analysis reveals
some fundamental conceptual problems within the theory. Various generalizations of empirical findings become questionable
because the theory allows different and contradicting possibilities to explain some empirical results. The article investigates
these theoretical problems by analyzing the conceptual distinctions between different kinds of cognitive load. It emphasizes
that reduction of cognitive load can sometimes impair learning rather than enhancing it. Cognitive load theory is reconsidered
both from the perspective of Vygotski’s concept of the zone of proximal development and from the perspective of research on
implicit learning. Task performance and learning are considered as related, but nevertheless fundamentally different processes.
Conclusions are drawn for the further development of the theory as well as for empirical research and instructional practice.
This study aims to understand the role that optimism could play in the context of a health asset approach to promote adolescent health-related quality of life (HRQOL). Adolescents (n = 948), between 11 and 16 years old from a medium-sized rural town in Sweden, answered questionnaires measuring optimism, pessimism, and HRQOL. The findings indicate a significant decrease in optimism and a significant increase in pessimism between early and midadolescence. The study has allowed us to present associational evidence of the links between optimism and HRQOL. This infers the potential of an optimistic orientation about the future to function as a health asset during adolescence and by implication may provide additional intervention tool in the planning of health promotion strategies. 相似文献
Reciprocal teaching is one of the most successfully implemented cooperative learning practices, yet many aspects of the process it follows are still unclear. The authors' aim was two-fold: To analyze whether reciprocal teaching activates diversity in discourse moves, communicative functions, and interaction sequences; and to determine whether reciprocal teaching needs to be based on prior work on student collaboration and cooperation skills in order to be effective (context dependency vs. context independency). Two groups with a different instructional background were compared: one with a teacher-centered and one with a student-centered approach. Forty-three third-grade students were led through a reciprocal teaching reading activity. Video recordings of each group were transcribed and analyzed at the micro level. Frequencies for each category were described and interpreted. The two groups did not differ significantly in the processes followed, indicating that reciprocal teaching is context independent and able to create interaction-rich and diverse environment. 相似文献
This paper examines what new materialist and posthumanist frameworks can offer learning science research in diverse maker learning environments. We explore what is gained by grappling with the entanglements between humans, non-humans and more-than-humans. To do this, we draw on Karen Barad's ethico-onto-epistemology and agential realism where she redefines connections to the shared world by attuning to the entangled matter that is created within intra-actions. We use this framework across four international cases: digital media camps, a university-level classroom-based makerspace, a Saturday outdoor makerspace workshop and a classroom-based museum makerspace. Each case study attends to how intra-actions enact agential forces in maker education research—forces that posthuman and new materialist frameworks help us see. In so doing, these case studies challenge many of the assumptions prevalent in the learning sciences about mattering and its implications in research sites. 相似文献
