"Genus är inskränkt!" : En komparativt inriktad studie av genuspedagogik på förskolor i New York och Stockholm

Levy, Ruby, Wickström, Sofia January 2014 (has links)
The purpose of this thesis is to examine how teachers work and reflects on gender education in preschools. We also want to take part of how teacher’s thoughts are reflected in the physical indoor environment and how the environment is designed by reviewing the rooms furnishing and the selected materials. We will do this by visiting a number of preschools located in Stockholm and New York. We have chosen three questions to get the answers on our purpose. How teachers reflect around gender pedagogy are, and how the thoughts are expressed in the practical work. How the teachers communicate with their co-workers about gender pedagogy. How the teachers own thoughts and reflections on gender pedagogy have been expressed in the physical indoor environment where the children stay during the day.  We have used interviews and observations as a method to gather the information that we needed to answer our questions of the thesis. We have used the sociocultural perspective, variation theory and queer theory as a ground to analyze our gathered information. As a conclusion we have found that the teachers have different ways of reflecting about gender pedagogy but they still don´t want to focus their work on it. They would rather focus their pedagogy on working with equality, which for them means more than just gender. We have reached that to find a way you work sustainable with gender pedagogy you have to have an open minded attitude towards the children, have critical standards, and an environment where children can grow and learn without focusing on gender.

The design of journals used for reflection

Lynch, Maureen January 2005 (has links)
This thesis examines the development of reflective skills. Reflection has been recognised as a prime mode of creating knowledge for project managers. Reflection literature indicates that reflective skills do not develop naturally; guidance, encouragement and facilitation is usually required for managers to reach their highest learning potential. Among the tools suggested to aid this development are written project journals. While there has been research on some aspects of journals, there was little found on the design of reflective journals relevant to developing project management reflection skills. This study has examined the effect or influence of various designs of reflective journals on different facets of reflective learning. The research question was: ????Are there facets of reflection that can be influenced by journal design????? Evidence for the study was first gathered through literature then from journal content and interviews. Literature on reflective learning revealed the facets relevant to the study: definition of reflection, consequences, emotions, temporal factors and individual and organisational culture. Issues identified in journal literature that needed to be applied to the study of reflection development included the journal audience, assessment and format. Participants in the study were final year undergraduates and Masters students who worked on industry based projects over several months. They were requested to keep journals for the duration of the projects, to submit them for examination and then asked to offer feedback on the various journal designs on completion of the projects. The research was conducted over four years, through seven projects, with thirty students taking part. The journal design went through six modifications. The primary findings from the study were: the majority of participants followed the predicted development hierarchy of reflective development; development of reflective skills is dependent on individual and organisational culture; audience does have an impact on reporting of and reflection on concerns; and journal design can facilitate development of some levels of reflection but has no influence on the development of critical reflection. / Masters by research thesis

Mind shift: creating change through narrative learning cycles

Grainger, Jenny Elizabeth January 2007 (has links)
This thesis explores the process of an annual appraisal strategy, ‘clinical conversation’, from the perspective of seven nurses who were assessed using this technique. The findings demonstrate that clinical conversation is a strategy which facilitates reflection, both as a solitary exercise and with others, to ensure that learning from experience is optimized. The research used a qualitative interpretive approach informed by the model of Grounded Theory espoused by Strauss and Corbin. All eight nurses who were assessed using the clinical conversation strategy were advanced practitioners working within the scope of sexual and reproductive health. Two of the actual appraisals were observed and seven of the nurses were interviewed within eight weeks of being assessed. The outcome of the clinical conversation was primarily one of learning; the acquisition of new insights into self as practitioner. The learning was facilitated through the process of narration; telling the story of clinical practice. Three distinct narrative cycles were identified, each an experiential learning episode. The experience of undertaking a variety of assessment activities created a narrative with self and triggered an internal reflective thinking process; the experience of working with a peer created an additional narrative, a mutual dialogue reflecting back on practice; the experience of sharing practice with an assessor created a further and final narrative, a learning conversation. Each narrative can be seen as a catalyst for change. Primarily, the nurses felt differently about themselves in practice, the way they saw themselves had shifted. Such a change can be described as an alteration in perspective. These alterations in perspective led all nurses to identify ways in which they would change their actual clinical practice. In this way the nurses attempted to align their espoused beliefs about practice with their actual practice. My study shows that each nurse responded differently to each narrative learning cycle: for some the conversation with the assessor was more of a catalyst for change than for others. In this way clinical conversation may be flexible enough to respond to a variety of differing learning styles. Learning was person specific which is an imperative for the continued professional development of already highly skilled clinicians. The implication of the research is that whilst clinical conversation was designed as a tool for appraising clinical competence, its intrinsic value lies in supporting the professional development of nurses.

Infrared Reflection-Absorption Spectrometry and Chemometrics for Quantitative Analysis of Trace Pharmaceuticals on Surfaces

Perston, Benjamin Blair January 2006 (has links)
Cleaning validation, in which cleaned surfaces are analysed for residual material, is an important process in pharmaceutical manufacturing and research facilities. Current procedures usually consist of either swab or rinse-water sampling followed by analysis of the samples. The analysis step is typically either rapid but unselective (conductivity, pH, total organic carbon, etc.), or selective but time-consuming (HPLC). This thesis describes the development of an in situ surface-spectroscopic analysis that removes the need for swab sampling and is both rapid and selective. This method has the potential to complement existing analyses to increase the efficiency of cleaning-validation protocols. The spectrometric system consists of a Fourier-transform infrared (FTIR) spectrometer coupled to a fibre-optic grazing-angle reflectance probe, and allows the measurement of infrared reflection-absorbance spectra (IRRAS) from flat surfaces in ~10 s. Multivariate chemometric methods, such as partial least squares (PLS) regression, are used to exploit the high information content of infrared spectra to obtain selective analyses without physical separation of the analyte or analytes from whatever interfering species may be present. Multivariate chemometric models require considerably more effort for calibration and validation than do traditional univariate techniques. This thesis details suitable methods for preparing calibration standards by aerosol deposition, optimising and validating the model by cross- and test-set validation, and estimating the uncertainty by resampling and formula-based approaches. Successful calibration models were demonstrated for residues of acetaminophen, a model active pharmaceutical ingredient (API), on glass surfaces. The root-mean-square error of prediction (RMSEP) was ~0.07 µg cm⁻². Simultaneous calibration for acetaminophen and aspirin, another API, gave a similar RMSEP of 0.06 µg cm⁻² for both compounds, demonstrating the selectivity of the method. These values correspond to detection limits of ~0.2 µg cm⁻², well below the accepted visual detection limit of ~1-4 µg cm⁻². The sensitivity of the method with a stainless steel substrate was found to depend strongly on the surface finish, with highly polished surfaces giving more intense IRRAS. RMSEP values of 0.04- 0.05 µg cm⁻² were obtained for acetaminophen on stainless steel with three different finishes. For this system, severe nonlinearity was encountered for loadings 1.0 µg cm⁻². From the results presented in this thesis, it is clear that IRRAS has potential utility in cleaning validation as a complement to traditional techniques.

EARLY CHILDHOOD STUDENT TEACHERS' REFLECTION ON THEIR PROFESSIONAL DEVELOPMENT AND PRACTICE: A LONGITUDINAL STUDY

SUMSION, Jennifer January 1997 (has links)
During the past fifteen years there has been increasing interest in the role of reflection in professional development, especially amongst teacher educators. Yet although many preservice programs now place considerable emphasis on encouraging and assisting student teachers to reflect on their practice, reflection remaings a problematic notion. There is little consensus, for example, about what constitutes reflection, how it might be identified, and whether it can be promoted. This thesis reports a longitudinal study conducted over four years which explored the above issues within the context of an early childhood teacher education program, in Sydney (NSW), Australia. The specific purpose of this study was to investigate changes in student teachers' reflection on their professional development and practice during their enrolment in the Guided Practice component of their preservice program. A strength of this study is its focus on reflection as a multidimensional phenomenon involving far more than the processes of analytical thought typically addressed by most previous research in this area. Drawing on an eclectic range of literature, this thesis argues that emotion, imagination, intuition, and contemplation can also play an integral role. As such, it asserts that reflection can be seen, in effect, as a complex and holistic search for meaning. Conceptualising reflection in this holistic manner raises numerous methodological challenges. These challenges and the methodological decisions made in response to them are outlined prior to developing profiles of the participants' reflection. These profiles indicated that there was little consistent change in the reflection of eight of the 18 participants. For four student teachers, on the other hand, there was some change, while for six, there was considerable change. Several factors which appeared instrumental in hindering or promoting these student teachers' reflection are identified. These include commitment (or lack of) to teaching and to reflection; an epistemological perspective of received or constructed knowing; and the extent to which the learning environment was perceived as supportive. The study concludes with a discussion of some of the implications for teacher educators and for those intending to undertake further research into reflection.

Exploring the use of a web-based virtual patient to support learning through reflection

Chesher, Douglas January 2004 (has links)
This thesis explores the support of learning through reflection, in the context of medical students and practitioners, working through a series of simulated consultations involving the diagnosis and management of chronic illness. A model of the medical consultative process was defined, on which a web-based patient simulation was developed. This simulation can be accessed over the Internet using commonly available web-browsers. It enables users to interact with a virtual patient by taking a history, examining the patient, requesting and reviewing investigations, and choosing appropriate management strategies. The virtual patient can be reviewed over a number of consultations, and the patient outcome is dependant on the management strategy selected by the user. A second model was also developed, that adds a layer of reflection over the consultative process. While interacting with the virtual patient users are asked to formulate and test their hypotheses. Simple tools are included to encourage users to record their observations and thoughts for further learning, as well as providing links to web-based library resources. At the end of each consultation, users are asked to review their actions and indicate whether they think their actions were critical, relevant, or not relevant to the diagnosis and management of the patient in light of their current knowledge. Users also have the opportunity to compare their activity to their peers or an expert in the case under study. Three formal cycles of evaluation were undertaken during the design and development of the software. A number of clinicians were involved in the initial design to ensure there was an appropriate structure that matched clinical practice. Formative evaluation was conducted to review the usability of the application, and based on user feedback a number of changes were made to the user interface and structure of the application. A third, end user, evaluation was undertaken using a single case concerning the diagnosis and management of hypertriglyceridaemia in the context of Type 1B Glycogen Storage Disease. This evaluation involved ten medical students, five general practitioners and two specialists. The evaluation involved observation using a simplified think-aloud, as well as administration of a questionnaire. Users were engaged by the simulation, and were able to use the application with only a short period of training. Usability issues still exist with respect to the processing of natural language input, especially when asking questions of the virtual patient. Until such time that natural language recognition is able to provide satisfactory performance, alternative, list-based, methods of interaction will be required. Evaluation involving medical students, general practitioners, and specialist medical practitioners demonstrated that reflection can be supported and encouraged by providing appropriate tools, as well as by judiciously interrupting the consultative process and providing time for reflection to take place. Reflection could have been further enhanced if users had been educated on reflection as a learning modality prior to using SIMPRAC. Further work is also required to improve the simulation environment, improve the interfaces for supporting reflection, and further define the benefits of using this approach for medical education and professional development with respect to learning outcomes and behavioural change.

Student attitudes towards and perceptions of ePortfolios in a first year Japanese language programme

Moffat, Sonja January 2008 (has links)
Research into learner autonomy has confirmed the importance of learner competencies such as effective strategy use, goal setting and planning, maintaining motivation, and the ability to reflect and self-evaluate to the development of autonomy. The introduction of key competency frameworks to develop learner autonomy has been a focus of recent curriculum development from primary through to tertiary levels in the New Zealand education system. However, facilitating and managing the development of these learning competencies in a programme of study that has a number of different papers and staff, can be problematic. The learning portfolio is emerging as a possible medium to provide the required framework. This study investigated the effectiveness of an ePortolio in enhancing learner autonomy in the context of a language learning programme. The aim of this study was to gain insight from a student perspective into the usfulness of ePortfolios as a tool to enhance student learning. Investigating learner autonomy and the development of self-reflection resulting from the use of ePortfolios was the main focus of the study. It also examined some of the practicalities of using an ePortfolio to develop the desired learner competencies, and discussed whether an ePortfolio provides an effective framework to record, monitor and provide feedback to students. The results of the study reinforce the findings of previous studies in that there are benefits of ePortfolios as they encourage reflection. ePortfolios also have the potential to support the reflective process by making learning outcomes visible and they promote goal-setting. However, despite these apparent benefits, the findings suggest that there are many challenges, which have the potential to negatively influence its effectiveness. The ePortfolio in this study was used with varying degrees of success. The findings have raised several issues regarding the introduction of an ePortfolio. The time it takes for teachers to give individual feedback and maintain an adequate level of feedback throughout the semester was one major challenge. The extent to which learners need to be trained in the purpose of the ePortfolio and its link to reflection and developing autonomy was another issue that was raised. In addition, getting students to reflect on their learning holistically also proved to be problematic. Overall however, findings as to the effectiveness of the ePortfolio in promoting autonomous learning appear promising, but they have highlighted the need to make changes to the ePortfolio itself. Its integration into the curriculum needs to be reconsidered to maximize its use and gain maximum benefit.
