Placing cybereducation in the UK classroom     

Daniel A. Menchik 《British Journal of Sociology of Education》2004,25(2):193-213

The use of the Internet in the classroom has often been characterized as a practice that disconnects the teacher from traditional forms of externally imposed influence. This paper examines this assertion by mapping the emerging field of cybereducation and considering how endemic knowledge is contextualized by national curricular authorities. The field theories of Pierre Bourdieu and Basil Bernstein are employed in order to demonstrate the relationship between expert discourse and classroom pedagogy, using the National Grid for Learning (NGfL) as a case study. This attempt to capture the dynamics of cybereducation ultimately suggests how this emergent intellectual field’s fragmentation and decoupling from State education forces offers policymakers the capacity to influence use. Progress of the UK government in integrating knowledge from an emergent educational field with its incumbent priorities is gauged, demonstrating the way in which national education officials have attempted to constrain potential departures from unregulated, officially mandated curriculum.  相似文献   

La Maîtrise Intuitive des Relations entre Masse,Volume et Masse Volumique Chez des Elèves du Premier Cycle     

Etienne Mullet  Daniel Vidal 《European Journal of Psychology of Education - EJPE》1986,1(3):47-65

Three experiments have been devoted to the application of the methodology developped by Anderson, N. H. (1981, 1982) in the framework of the Information Integration Theory to the problem of the mastery by children (14 old) of the relations between the notions of mass, volume and volumic mass. It appears that, having to judge of the mass values of diverses objects from given values of volume and volumic mass, a majority of pupils are able to take account of the positive link between the mass on the one part and the volume and the volumic mass on the other part but apply an additive type integration rule. However, a minority of pupils are able to apply a normatively correct multiplicative rule. Concerning the judgements of volume values from given mass and volumic mass values, and the judgements of volumic mass values from given mass and volume values, a majority of pupils apply a soustractive integration rule. In these two cases however the integration patterns are extremely variegated. The relation between the algebraic level of analysis of the judgement data and an information processing level of analysis of the same data is discussed. The use by teachers of the paradigm presented in the study with the aim of improving upon the current evaluation methods is proposed.  相似文献   

Conditioned inhibition in feature negative discrimination learning with pigeons     

Daniel S. Gokey  Robert L. Collins 《Learning & behavior》1980,8(2):231-236

Discrimination performance was investigated with pigeons using feature negative (FN) discrimination procedures which differed in the temporal arrangement of the stimuli on S? trials. In both procedures, a single common element was presented on reinforced (S+) trials. In thesimultaneous FN procedure, a distinguishing element was presented simultaneously with the common element of S? trials. In thesequential FN procedure, the distinguishing element preceded onset of the common element on S? trials. In two experiments, the sequential FN procedure yielded better discrimination performance. In Experiment 1, a summation test designed to separate learning and performance variables indicated that sequential FN subjects had learned the negative relationship between the distinguishing element and reinforcement while simultaneous FN subjects had not. In Experiment 2, summation and acquisition tests indicated that the distinguishing element developed inhibitory properties in the sequential FN procedure but not in the simultaneous FN procedure.  相似文献

Evaluating a computer‐based reading programme with children with Intellectual Disabilities: feasibility and pilot research     

Emily J. Roberts-Tyler  John Carl Hughes  Richard P. Hastings 《Journal of Research in Special Educational Needs》2020,20(1):14-26

Increasing evidence indicates that individuals with Intellectual Disabilities (ID) might benefit from phonics‐based reading instruction. However, research and instruction in this field has predominantly focused on sight word reading. Models for complex interventions recommend that feasibility research be conducted prior to conducting randomised studies to assess efficacy of interventions (Thabane et al., 2010). The aim of the current paper is therefore to investigate feasibility questions relating to conducting a full‐scale randomised controlled trial (RCT) evaluation of an online, phonics‐based reading programme (Headsprout^? Early Reading; HER) with children with ID. Employing a randomised pre‐test post‐test group design, this study explores and trials important aspects of a RCT evaluation to inform a full‐scale RCT. We also found that HER had a significant effect on reading skills when compared with ‘education as usual’, with large effect sizes on the main outcome measure. This indicates that further, more robust evaluations using HER with children with ID are a worthwhile pursuit.  相似文献   

Constructing a Joint Story-Writing Space: The Dynamics of Young Children's Collaboration at Computers     

Ya-hui Chung  Daniel J. Walsh 《Early education and development》2006,17(3):373-420

This study explored kindergartners' and first graders' collaborative processes to understand the nature of peer collaboration and the learning opportunities afforded by peer discourse. Data were drawn from 6 dyads who participated in a computer writing project for 2 school semesters. Children's videotaped interactions were analyzed with the focus on understanding how children's collaborative roles and patterns changed over time. Examination of video data and children's computer products revealed that (a) children's interaction patterns changed from a more independent style toward a more integrative style, as shown in their distribution of control over mouse and keyboard and in the written outcomes of their collaboration; (b) a shift in role patterns emerged across repeated instances of peer collaboration so that children began alternating the roles of leader and observer, and less competent children began carrying out more important tasks; and (c) the computer served as an object of reference for children to sustain their interaction and stay on task.  相似文献

Tailoring an information skills programme for Trainee Nursing Associates     

Daniel Froste 《Health information and libraries journal》2020,37(1):89-93

This feature describes the tailored information skills programme which was delivered for the second cohort of Trainee Nursing Associates (TNAs) at Barnsley Hospital NHS Foundation Trust and presents the results of the evaluation which was undertaken. Literature searching and critical appraisal were offered to the first cohort. Feedback was collated, and sessions were refined and tailored to better meet the information needs of the second cohort of TNAs. A comparison of confidence ratings before and after the programme ascertained whether the information skills programme had a positive benefit in confidence levels of attendees. D.I.  相似文献   

Health informatics in Chile: responding to health reforms     

Capurro D 《Health information and libraries journal》2007,24(4):287-291

Chile is in the throes of health reforms aimed at ensuring that every person with specified chronic diseases receives timely and high quality care. CITs are crucial to the achievement of this vision because they make it possible to manage information and knowledge in a more efficient way. Until a few years ago, the incorporation of CITs was limited to individual initiatives, but since 2004 there has been a master plan to coordinate this task in the public sector. Some projects are now operative but there is still a long road to travel before getting to our destination. One of the most underdeveloped areas is the clinical applications of health CITs, especially the incorporation of biomedical knowledge to clinical practice. The two biggest challenges facing the Digital Agenda for the health care system are (i) to develop a critical mass of clinicians and health related professionals with expertise in Health Informatics; and (ii) to foster technical integration of the private and public sectors of the health care market.  相似文献   

Maintenance of responding when reinforcement becomes delayed     

Costa DS  Boakes RA 《Learning & behavior》2007,35(2):95-105

In four experiments with rats, we examined the persistence of behavior when reinforcement was switched from immediate to delayed. In Experiment 1, lever pressing elicited by instrumental training with immediate reinforcement continued when a 20-sec delay of reinforcement was introduced (easy-to-hard condition), whereas when the delay condition was introduced from the start (hard-to-hard condition), responding remained low throughout. A similar result was obtained in Experiment 2, in which lever pressing was elicited by a classical conditioning (autoshaping) procedure. In Experiment 3, rats initially trained with delayed reinforcement continued to respond at a low rate when switched to immediate reinforcement (hard-to-easy condition). By measuring magazine entry (goal tracking) as well as lever pressing (sign tracking) in Experiment 4, we confirmed that such transfer effects at least partly involve the persistence of whatever type of behavior was initially dominant.  相似文献
