Parent/professional partnership is a key theme in government policy and service delivery for parents of disabled children, yet there is little evidence of such partnerships in research. Drawing on the literature concerning parents' experiences of caring for and raising a child with additional needs; parental involvement and partnerships and the social analysis of disability, this article sets out the rationale for parents' participation in educational research. It proposes a parents' participatory research approach adapted from a disability or emancipatory research paradigm, which the author used when conducting her doctoral research. She describes how there was evidence of parental participation in the study on three levels, through, firstly, the parent/researcher who initiated and co-ordinated the study; secondly, the parents' advisory group, who advised the researcher, completed some analysis and discussed the findings and, thirdly, the parents in the sample, who were offered opportunities to participate, for example, in decisions concerning the content of the data and development of the research methods that were used. Finally, the article discusses to what extent the parents participating in this study were given a voice to express their views, some control over the research process and so were treated as partners in the research process. It concludes that this research study has extended the notion of working in partnership with parents to the field of research and demonstrated that a parents' participatory research approach is possible. It now needs to be developed and replicated in other studies with parents of disabled children.  相似文献

Abstract

Although stakeholder participation is expected to promote equitable and sustainable natural resource management, lessons from the past tell us that more careful attention needs to be paid to achieving equitable impacts. Now the question is how to address social inequities and power asymmetries. Some authors emphasize the need for more dialogue, while others prefer a critical perspective, arguing that dialogue might not be sufficient to avert the risk of a process deepening existing social inequities. This article aims to enrich this debate and question the practical implications of the critical perspective through an in-depth analysis of power games in a participatory process.

A Companion Modelling (ComMod) process was conducted in an Akha community of Northern Thailand with a critical perspective, i.e. with a concern for the less influent stakeholders. Simulation tools such as role-playing games were used to mediate a cross-cultural learning process among researchers, farmers and administrators about a local irrigation water management problem. The detailed analysis of power games in this learning and negotiation process reveals that in spite of initial power asymmetries, the poorest farmers of the community started to voice and assert their interests. This was very much due to the role of a Western researcher who put the equity issue on the public agenda and to the strategic support of a charismatic Christian leader.

We identify a set of practical facilitation methods that helped to manage power asymmetries and to level the playing field, but we also discuss the main limits of our cultural-embedded methodological choices. Acknowledging that ‘the facilitators’ neutrality' is an illusion, this study allows us to raise the question of their social legitimacy. We suggest that they should systematically make explicit and reflect on their cultural-ideological background and methodological hypothesis and choices and their effects on the socio-political context. This article is an original attempt to accept this challenge.  相似文献

Cell fusion consists of inducing the formation of a hybridoma cell containing the genetic properties of the progenitor cells. Such an operation is usually performed chemically or electrically. The latter method, named electrofusion, is considered as having a strong potential, due to its efficiency and non-toxicity, but deserves further investigations prior to being applicable for key applications like antibody production and cancer immunotherapy. Indeed, to envision such applications, a high amount of hybrid cells is needed. In this context, we present in this paper a device for massive cell pairing and electrofusion, using a microarray of non-connected conductive pads. The electrofusion chamber––or channel––exposes cells to an inhomogeneous electric field, caused by the pads array, enabling the trapping and pairing of cells with dielectrophoresis (DEP) forces prior to electrofusion. Compared to a mechanical trapping, such electric trapping is fully reversible (on/off handling). The DEP force is contactless and thus eases the release of the produced hybridoma. Moreover, the absence of wire connections on the pads permits the high density trapping and electrofusion of cells. In this paper, the electric field mapping, the effect of metallic pads thickness, and the transmembrane potential of cells are studied based on a numerical model to optimize the device. Electric calculations and experiments were conducted to evaluate the trapping force. The structure was finally validated for cell pairing and electrofusion of arrays of cells. We believe that our approach of fully electric trapping with a simple structure is a promising method for massive production of electrofused hybridoma.  相似文献

Infants’ abilities to focus attention on objects are known to be related to mothers’ mobilizing behaviors. As delayed effects of maternal behaviors at 5 months may be observed in 8-month-olds, mothers may be considered as scaffolding their infant’s attention. However, all dyadic activities are probably not equally propitious to attention mobilizing. In a sample of 30 dyads, studied at 5 and 8 months of age, whole observations were split in four broad categories: care, dyadic play with objects, dyadic play without objects and infant alone. The duration of maternal mobilizing and infant attention focussing were studied within categories. Inter-dyads variability is high, while dyads are stable across ages. Even within the dyadic play with objects, mothers differ widely in the duration and way they mobilize attention. Five-month-olds still need their mother’s support, as they explore less when they are alone, while 8-month-olds are more autonomous. The impact and importance of the various types of dyadic activities on cognitive development are discussed.  相似文献

Gagnon and Doré (1992) showed that domestic dogs are able to solve a Piagetian object permanence task called the invisible displacement problem. A toy is hidden in a container which is moved behind a screen where the toy is removed and left. Dogs make more errors in these problems than they do in visible displacement tests, in which the object is hidden directly behind the target screen. In Experiment 1, we examined components of the standard procedure of invisible displacements that may make encoding or retention of the hiding location more difficult than it is in visible displacements. In Experiment 2, we compared dogs’ performances in visible and invisible displacement problems when delays of 0, 10, and 20 sec were introduced between the object’s final disappearance and the subject’s release. The results revealed that dogs’ poorer performance in invisible displacement tests is related to the complex sequence of events that have to be encoded or remembered as well as to a difficulty in representing the position change that is signaled, but not directly perceived.  相似文献

The crawling behavior of sixty 2-day-old newborns was studied while they were supported prone on a mini skateboard and on a pediatric mattress without additional support. Analyses of the number and types of limb movements and their characteristics, the coactivation of limb pairs, and the displacement across the surface, revealed that newborns can crawl with locomotor patterns similar to those documented during quadrupedal locomotion in animals and human adults. This was particularly apparent on the skateboard. This discovery suggests that locomotor circuitry underlying quadrupedal locomotion develops during fetal life. Drawing upon other evidence for a quadrupedal organization underlying bipedal gait, we argue that early quadrupedal training may enhance interventions designed to hasten the onset of independent walking.  相似文献

We will attempt a synthesis from various research perspectives that have analyzed the alterations that knowledge inevitably goes through while percolating into classroom activities. We will try to identify some of their causes and will illustrate them with examples in genetics. First, we will discuss some research on knowledge transformation when genetics knowledge is popularized (Staerklé and Clémence 2002), to show how knowledge is transformed in specific predictable manners as it moves from experts to general public. Then, we will draw from a large body of (French) research in didactic transposition (Chevallard 1991) in order to highlight what knowledge characteristically thrives or is lost as it percolates into school practice and learner’s knowledge. We will then draw from Huberman’s (Science Communication, 4(4), 478–510, 1983) analysis of knowledge use in schools the specificities of knowledge that teachers effectively use. All three perspectives reveal that cognitive and social environment are crucial determinants of what knowledge will be found in schools. An ecological metaphor explains how different cognitive environments from research into education favor knowledge adapted to specificities of this ecosystem. This transposition of knowledge is therefore not decay but inescapable and necessary. Ignoring this transposition has considerably reduced the effectiveness of many educational reforms. We will combine these three to propose an evolutionary perspective that could inform ways of expressing research into educational recommendations fed into the system to optimize the didactic transposition process.  相似文献

Evaluation of professional development (PD) has traditionally been composed of summative and formative feedback, and has focused on assessing the extent to which the PD impacts participating teachers’ knowledge, beliefs, and practices. This study establishes an additional purpose for PD evaluation – as educative opportunities for professional developers, particularly for PD providers who are university-level content specialists (e.g. scientists, mathematicians, statisticians, engineers). Through analysis of data collected as state-wide evaluators for one US Midwest state’s Improving Teacher Quality Grant PD programs, and utilizing an analysis methodology which we term ‘recommendation traces,’ we examine formative evaluation recommendations that we made to four different PD projects over three years. Findings from this study shed light on how content specialists who work in PD projects can learn about effective PD through project evaluation efforts.  相似文献
