The importance of reflection in experiential learning with community and youth workers for the learning age     

Mary Kenny  Sue Ralph  Marie Brown 《International Journal of Lifelong Education》2013,32(2):115-125

The New Labour government, in its Green Paper on the Learning Age, published in February 1998, put lifelong learning at the heart of its programme. In this article we aim to demonstrate that there is a direct parallel between the processes outlined in the Green Paper and the processes of experiential learning and community development by focusing on the Diploma in Community and Youth Work Studies run by the Community Work Unit (CWU) based in the Centre for the Development of Continuing Education at the University of Manchester.

Community action provides a setting for informal education. Community workers are in a unique position in relation to developing the potential for learning in the groups and individuals with whom they work. Their education and training should enable them to articulate and value their experience and reflect upon it in order to establish a meaningful basis for further self- and/or community development. We will explore how the CWU uses participative learning methods which recognize, value and use the experience and understanding of the participants as a basis for their own and others’ learning, and the relevance of these learning methods to the work practice of the participants.  相似文献

Biodeterioration of Incralac used for the protection of bronze monuments   总被引：2，自引：0，他引：2

Outdoor bronze sculptures are highly susceptible to corrosion in many environments and organic coatings are widely used for their protection. The purpose of this study was to determine the susceptibility of the commonly used coating Incralac to biodeterioration by microorganisms. A yeast was isolated from a bronze statue treated with Incralac and its ability to degrade Incralac was determined using growth curves, scanning electron microscopy (SEM), and electrochemical impedance spectroscopy (EIS). The organism grew slowly on Incralac in liquid culture, but SEM images demonstrated its ability to adhere to Incralac coated metal. Additionally, the yeast caused a rapid drop in the low frequency impedance of Incralac coated metal that was not observed under sterile conditions, indicating that the organism accelerated deterioration of the coating. The potential for microbial growth to accelerate deterioration of Incralac should be considered when developing a maintenance strategy for the protection of outdoor metal monuments.  相似文献

Dipe-D: A Tool for Knowledge-Based Query Formulation in Information Retrieval     

Ruud van der Pol 《Information Retrieval》2003,6(1):21-47

The paper reports the development of Dipe-D, a knowledge-based procedure for the formulation of Boolean queries in information retrieval. Dipe-D creates a query in two steps: (1) the user's information need is developed interactively, while identifying the concepts of the information need, and subsequently (2) the collection of concepts identified is automatically transformed into a Boolean query. In the first step, the subject area—as represented in a knowledge base—is explored by the user. He does this by means of specifying the (concepts that meet his) information need in an artificial language and looking through the solution as provided by the computer. The specification language allows one to specify concepts by their features, both in precise terms as well as vaguely. By repeating the process of specifying the information need and exploring the resulting concepts, the user may precisely single out the concepts that describe his information need. In the second step, the program provides the designations (and variants) for the concepts identified, and connects them by appropriate operators. Dipe-D is meant to improve on existing procedures that identify the concepts less systematically, create a query manually, and then sometimes expand that query. Experiments are reported on each of the two steps; they indicate that the first step identifies only but not all the relevant concepts, and the second step performs (at least) as good as human beings do.  相似文献

Acquiring an attacking forehand drive: the effects of static and dynamic environmental conditions     

R J Bootsma  M H Houbiers  H T Whiting  P C van Wieringen 《Research quarterly for exercise and sport》1991,62(3):276-284

Two groups of 10 novice subjects each were trained to perform attacking forehand drives in table tennis and land the balls as fast and as accurately as possible onto a target on the opposite side of the net under two different training conditions. Under the static training condition, the balls were to be struck from a constant position, and under the dynamic training condition, balls approached the subjects in a normal way. Both groups were tested under dynamic conditions prior to and after four days of training, during which they received 1,600 practice trials. Both groups of subjects were shown to increase the number of balls that landed on the target, and learning was also evident from an increased consistency of the direction of travel of the bat at the moment of ball/bat contact. However, no increase in consistency was found for the location of the bat at the moment of ball/bat contact and for the movement times. Thus, learning can occur in the absence of externally generated time-to-contact information, but this is not due to the establishment of a consistent movement form. Learning appears to progress from control at the moment of ball/bat contact backward, toward the moment of initiation.  相似文献   

Two secondary teachers’ understanding and classroom practice of dialogic teaching: a case study   总被引：1，自引：0，他引：1  

Janneke van de Pol  Sue Brindley  Rupert John Edward Higham 《Educational studies》2017,43(5):497-515

Dialogic Teaching (DT) is effective in fostering student learning; yet, it is hard to implement. Little research focused on secondary teachers’ learning of DT and on the link between teachers’ understanding and practices, although these two are usually strongly intertwined. Using a wide range of evidence, this case study systematically investigated and compared two secondary teachers’ understanding and practice of DT during their participation in a continuing professional development programme (CPDP). The CPDP appeared effective to some extent. The History teacher’s understanding of DT, i.e. being a co-learner, appeared highly effective in implementing DT, whereas the Mathematics teacher’s understanding of DT, i.e. creating a democratic learning environment, seemed only effective to some extent. Focusing on both teachers’ understanding and practice when developing DT seemed fruitful in explaining differences in practice. Future research could further explore to what extent understanding DT as being a co-learner facilitates professional development.  相似文献   

What lies beneath: exploring the deeper purposes of feedback on student writing through considering disciplinary knowledge and knowers     

Martina van Heerden  Sharita Bharuthram 《Assessment & Evaluation in Higher Education》2017,42(6):967-977

Feedback plays an integral role in students’ learning and development, as it is often the only personal communication that students have with tutors or lecturers about their own work. Yet, in spite of its integral role in student learning, there is disagreement between how students and tutors or lecturers perceive the pedagogic purpose of feedback. Central to this disagreement is the role that feedback has to play in ensuring that students produce the ‘right’ kinds of knowledge, and become the ‘right’ kinds of knowers within their disciplines. This paper argues that, in order to find common ground between students and tutors or lecturers on what feedback is for, and how to both give and use it effectively, we need to conceptualise disciplinary knowledge and knowers anew. We offer, as a useful starting point, the Specialisation dimension of Legitimation Code Theory as both practical theory and methodological tool for exploring knowledge and knowers in English Studies and Law as two illustrative cases. The paper concludes that this analysis offers lecturers and tutors a fresh understanding of the disciplinary knowledge and knower structures they work within and, relatedly, a clearer view of the work their feedback needs to do within these.  相似文献
