Evaluating metacognitive scaffolding in Guided Invention Activities     

Ido Roll  Natasha G. Holmes  James Day  Doug Bonn 《Instructional Science》2012,40(4):691-710

Invention and Productive Failure activities ask students to generate methods that capture the important properties of some given data (e.g., uncertainty) before being taught the expert solution. Invention and Productive Failure activities are a class of scientific inquiry activities in that students create, implement, and evaluate mathematical models based on data. Yet, lacking sufficient inquiry skills, students often do not actualize the full potential of these activities. We identified key invention strategies in which students often fail to engage: exploratory analysis, peer interaction, self-explanation, and evaluation. A classroom study with 134 students evaluated the effect of supporting these skills on the quality and outcomes of the invention process. Students in the Unguided Invention condition received conventional Invention Activities; students in the Guided Invention condition received complementary metacognitive scaffolding. Students were asked to invent methods for calculating uncertainties in best-fitting lines. Guided Invention students invented methods that included more conceptual features and ranked the given datasets more accurately, although the quality of their mathematical expressions was not improved. At the process level, Guided Invention students revised their methods more frequently and had more and better instances of unprompted self-explanations even on components of the activity that were not supported by the metacognitive scaffolding. Classroom observations are used to demonstrate the effect of the scaffolding on students’ learning behaviours. These results suggest that process guidance in the form of metacognitive scaffolding augments the inherent benefits of Invention Activities and can lead to gains at both domain and inquiry levels.  相似文献

Responding to students' needs in special schools in Ireland and England: findings from two schools     

Therese Day  Anita Prunty  Maeve Dupont 《Journal of Research in Special Educational Needs》2012,12(3):141-150

As more students with special educational needs attend mainstream schools, it is critical that the role and operation of special schools be examined. This article reports on two case studies, one special school in England and one in Ireland, which formed part of a national review of the role of special schools and special classes in Ireland. Two students, in each case study school, were shadowed and observed during two‐day visits by the research team. These students, and everyone belonging to them, were interviewed and relevant documents were analysed. Findings are discussed in terms of responding to students' needs through: organization of teaching and learning, curriculum, leadership, specialist staff, collaboration and links outside the special school. The implications are considered with reference to research, policy and practice and the authors conclude that the evidence provides support for maintaining the special school as an integral part of the continuum of educational provision for students with special educational needs.  相似文献   

Theoretical elastoplastic analysis for foundations with geosynthetic-encased columns     

Yuan-yu Duan  Yi-ping Zhang  Dave Chan  Ya-nan Yu 《浙江大学学报(A卷英文版)》2012,13(7):506-518

As a new technique in ground improvement, geosynthetic-encased columns (GECs) have promising applications in soft soil foundation. By assuming yielding occurs in the columns while the surrounding soil and the geosynthetic remain elastic, an elastoplastic analytical procedure for foundations improved by GECs is proposed. The radial stresses that the geosynthetic provides and the elastoplastic deformations of the foundation resting on a rigid base are derived. A comparison with finite element analysis shows that the proposed method is effective and can provide a reasonable prediction of a GEC??s deformation. Subsequent parametric analysis indicates that higher geosynthetic stiffness leads to better performance of the composite foundation. The optimum length of encasement is related to the load acting on the foundation and the permissible vertical and radial displacements of the column. Moreover, as the dilation angle of the column increases, the settlement decreases, especially under high loading. The influence of the encasement is more significant in soils with smaller elastic modulus.  相似文献

Multiple influences on curriculum decisions in a supercomplex world     

Trevor Day  Paul Tosey 《Curriculum Journal》2013,24(4):515-534

This article extends currently reported theory and practice in the use of learning goals or targets with students in secondary and further education. Goal-setting and action-planning constructs are employed in personal development plans (PDPs) and personal learning plans (PLPs) and are advocated as practice within the English national policy agenda with its focus on personalisation. The article argues that frameworks widely used for goal setting and action planning by UK educational practitioners, in particular SMART targets or goals, have yet to be rigorously examined in the light of relevant theory and practice. Doing so is important given contemporary emphasis on the dimensions of the learner experience regarded by ‘learning to learn’ practitioners as underpinning effective learning in the modern classroom. The article draws from social cognitive theory and achievement goal theory, including Zimmerman's criteria for appropriate goals, to suggest an alternative framework for goal or target setting – ‘well-formed outcomes’, a construct from the field of neuro-linguistic programming (NLP). In comparison with SMART targets, the authors argue that well-formed outcomes offer a more rigorous and holistic approach, by taking greater account of the learner's identity, affective dimensions (feelings and emotions), social relations and values, as well as encouraging mental rehearsal.  相似文献   

Action research and reflective practice: towards a holistic view   总被引：5，自引：5，他引：0  

Ruth Leitch  Christopher Day 《Educational Action Research》2013,21(1):179-193

Two concepts that have captured the imagination of the educational community in the last 60 years have been those of ‘reflective practice’ and ‘action research’. Both, in their various forms, are considered to be critical dimensions of the professional development of teachers. However, whilst both were receiving academic attention during the 1930s and 1940s (Lewin, 1934, cited in Adelman, 1993; Lewin, 1946; Dewey, 1933), it was not until Stenhouse's (1975) notion of the teacher-as-researcher that the two came most compellingly into relationship and educational action research as a process, which held at its centre different kinds of reflection, began to be reformulated in Britain (Carr, 1993). This article considers the important part played in teachers' development by different kinds of action research. Its central thesis is that, although action research has a critical role to play not least as a means of building the capacity of teachers as researchers of their own practice, there has been insufficient attention given to both the nature of reflection in the action research process, and its relationship to the purposes, processes and outcomes. The article challenges the rational, cognitive models of reflection that are implicit in much of the action research literature. It suggests that more attention needs to be given to the importance of the role of emotion in understanding and developing the capacities for reflection which facilitates personal, professional and ultimately system change  相似文献   

Challenges to teacher resilience: conditions count     

Qing Gu  Christopher Day 《British Educational Research Journal》2013,39(1):22-44

Drawing upon findings of a four‐year national research project on variations in the work and lives of teachers in England, this paper provides empirical evidence which contributes to understandings about the importance of resilience in teachers' work. The experience of resilience as perceived by teachers in this research was that it was neither innate nor stable and was much more than a capacity to survive and thrive in extremely adverse circumstances. Rather, it was perceived as being closely allied to their everyday capacity to sustain their educational purposes and successfully manage the unavoidable uncertainties which are inherent in the practice of being a teacher. Their capacity to be resilient fluctuated as a result of the influences of the personal, relational and organisational settings in which they worked. The findings have implications for initial and in‐service professional development programmes, school leadership and the quality retention of teachers.  相似文献
