A Systems Approach to the Development of Enhanced Learning for Engineering Systems Design Analysis

Henshall, Edwin, Campean, Felician, Rutter, B. 09 May 2017 (has links)
yes / This paper considers the importance of applying sound instructional systems design to the development of a learning intervention aimed at developing skills for the effective deployment of an enhanced methodology for engineering systems design analysis within a Product Development context. The leading features of the learning intervention are summarised including the content and design of a training course for senior engineering management which is central to the intervention. The importance of promoting behavioural change by fostering meaningful learning as a collaborative process is discussed. Comparison is made between the instructional design of the corporate learning intervention being developed and the systems engineering based product design process which is the subject of the intervention.

Documenting Systemic Reform in Mathematics: A Case Study of One Middle School

Cauthen, Sandra Dalton 25 August 2003 (has links)
An operational definition of Systemic Reform is used to document a case study of mathematics education reforms occurring in the mathematics classrooms of one middle school in one school division in one state. The middle school had two lead teachers who participated in the training component of a National Science Foundation-funded state-wide Systemic Reform Initiative. Systemic Reform conceptualized reform as combining bottom-up reform with top-down support. Therefore, the research methodology confronted the challenges of the breadth and complexity of Systemic Reform through the use of selective data in the form of artifacts, interviews, and observations from four populations: (1) classroom teachers, (2) building administrators, (3) district administrators, and (4) state-level staff. The study was conducted at four levels over a five-year period to provide the focus for longitudinal data collection to document: (1) the status of mathematics education during the 1995-96 primary data collection year, (2) the evolution of mathematics education reform over the course of the five year period, and (3) the manner in which Systemic Reform occurred. All levels of educators involved made an initial five-year commitment as active participants in the State's Systemic Reform Initiative, but only the Lead Teacher actually carried through with this commitment. After the first year division-level administrators shifted the focus of reform efforts to the elementary schools and discontinued support for the middle schools; after the second year both the division and state-level administrators withdrew all support. Although changes were made at the school level which supported reform in mathematics education (i.e., adoption of constructivist-type instructional materials, purchase of classroom sets of manipulatives and calculators, implementation of block scheduling, and the organization of teachers in interdisciplinary teams) the necessary changes in technology, curriculum and assessment were not in place to support the reform efforts. Through the perseverance of the Lead Teacher some changes in mathematics classrooms were documented, but the lack of consistent administrative leadership/support and emphasis on multiple reforms ended in the all to common bandwagon phenomena at the building, division and state levels so characteristic of change efforts in schools. / Ph.

Therapists' Use and Management of Eating Disorder Lived Experience in the Treatment of Clients with Eating Disorders

King, Ashley Ayn 07 April 2022 (has links)
The treatment of eating disorders (EDs) presents many challenges. Therapists' reactions towards clients (countertransference) may further complicate treatment. Countertransference may be partially due to the therapist's own vulnerabilities. Due to the personal connection to the work, countertransference towards ED clients may be pronounced among therapists with eating disorder lived experience (EDLE). Previous research indicates that 25-50% of ED therapists have EDLE; yet, minimal research examines how therapists negotiate their experiences while treating ED clients. The existing literature largely operates from the assumption that EDLE is a liability. While therapists with EDLE have some distinct challenges, therapists with EDLE may also have a unique perspective to offer the ED profession. The present study sought to understand how therapists with EDLE use their EDLE as a resource in their clinical work with ED clients. The study was guided by the theoretical frameworks of social constructivism and symbolic interactionism, as well as the person-of-the-therapist clinical training philosophy. Using constructivist grounded theory methodology, semi-structured interviews (Mtime = 89 minutes) were conducted with 22 therapists with EDLE, who work with ED clients. Participants explored how they use and manage their EDLE during key tasks of treatment with their ED clients. Results revealed that therapists engaged in two, interconnected constellations of processes (systems) in order to use and manage their EDLE in clinical practice. The first system (The Central System) helps therapists transform their personal experiences into clinical guidance that they can use to inform their work. The second system (The Checks and Balances System) helps the therapist find a balance between connecting with the client, while also allowing for differences of experiences to emerge. Lastly, personal processes (personal meaning making, values surrounding authenticity, and stigma surrounding EDLE), existing outside of these systems, were also found to impact the ways in which therapists use and manage themselves. Findings have implications for the EDLE literature, by providing novel ways therapists can use their EDLE. Findings also have implications for the POTT framework by exploring how POTT can be adapted for therapists who share lived experiences with their clients. A POTT-EDLE is proposed for training therapists with EDLE. / Doctor of Philosophy / The treatment of eating disorders (EDs) presents many challenges (e.g., frequent comorbidity, high rates of relapse, and the life-threatening nature of the disorder). Therapists' reactions towards clients (countertransference) may further complicate treatment. Countertransference (e.g., worry, frustration, hopelessness) may be partially due to the therapist's own unresolved issues and vulnerabilities. Due to the personal and professional connections to the work, countertransference towards ED clients may be particularly pronounced among therapists with eating disorder lived experience (EDLE). Previous research indicates that 25-50% of ED therapists have EDLE; yet, minimal research examines how therapists use and manage their experiences while treating ED clients. The existing literature largely operates from the assumption that EDLE is a liability and therapists with EDLE are working from a deficit. While therapists with EDLE have some distinct challenges, therapists with EDLE may also have a unique perspective to offer the ED profession. The study sought to understand how therapists with EDLE use their EDLE as a resource in their clinical work with ED clients. Interviews were conducted with 22 therapists with EDLE who work with ED clients. Results revealed that therapists engaged in two systems in order to use and manage their EDLE in clinical practice. The first system (The Central System) helps therapists transform their personal experiences into clinical guidance that they can use to inform their work. The second system (The Checks and Balances System) helps the therapist find a balance between connecting with the client, while also allowing for differences of experiences to emerge. The Central System and The Checks and Balances System work in tandem in order for the therapist to both use and manage their EDLE. Results describe the multiple processes informing these systems. Lastly, personal processes (personal meaning making, values surrounding authenticity, and stigma surrounding EDLE), existing outside of these systems, were also found to impact the ways in which therapists use and manage themselves. Findings have clinical and training implications for how therapists with EDLE can use and manage their EDLE to inform their clinical work with ED clients.

Recommending Political Warfare--The Role of Eisenhower's Presidential Committee on International Information Activities in the United States' Approach to the Cold War

Finley, Sonya Lynn 17 November 2016 (has links)
In 1953 President Dwight D. Eisenhower charged an ad hoc advisory group with assessing the current U.S. Cold War effort and offering recommendations for an 'unified and dynamic' way forward. This work investigates the case of Eisenhower's Presidential Committee on International Information Activities and its role in the United States' approach to the Cold War. Problematizing that which is often taken for granted, this empirical, interpretive study uncovers the discursive conditions of possibility for and the discursive activities taking place within Jackson Committee decision making processes. Employing a constructivist discursive framework, this project builds on an understanding of policy making as a process of argumentation in which actors intersubjectively define problems and delimit policy and strategy options. Revealing discursive conditions of possibility enables a deeper understanding of the substance, tensions and discursive maneuvers informing subsequent U.S. strategy and policy choices during the Cold War and may offer insights into understanding and addressing geopolitical challenges in the 21st century. The thick analytic narrative illuminates the 'witcraft' involved in conceptualizing the unique threat posed by the Soviet Union whose practices challenged existing categories, and in extending wartime discourses to the post-war geopolitical environment. It examines discursive practices informing the nascent concepts of national strategy, psychological warfare, and political warfare, including arguments for constituent elements and relationships between them. In so doing, this dissertation conceptualizes national strategy as practices underpinning a prioritized drive for competitive advantage over adversaries. Additionally, political warfare represents practices intended to create and present alternatives to foreign actors that are in the U.S. interest through the integration and coordination of diplomatic, economic, military, and informational activities. Based on its conceptualization of a long-term adversarial competition with the Soviet Union, the committee recommended solutions for a sustainable national strategy of political warfare prioritizing the free world and liberal world order. Its recommendations sought to recast strategic panic into strategic patience. / Ph. D.

Development and Evaluation of Virtual World Instruction Based on a Constructivist Learning Environment Design Framework

Dannenberg, David Randall 16 January 2014 (has links)
By their very nature, physical classrooms limit the external resources that are readily available to teachers and students. However, many educators desire to expand the student's learning environment to include outside resources (Partnership for 21st Century Skills, 2009; NCSS, 2010; U.S. Dept. of Education, 2004). Much of this desire is due to the influence of constructivism; however, many teachers are without the knowledge and resources to implement a Constructivist Learning Environment (CLE) (Diem, 1999; Mason et al., 2000; Swan and Hofer, 2008). Therefore, how to create a suitable community-driven learning environment that allows classroom teachers to utilize resources outside their immediate location is a problem faced by many of today's educators. Past research has identified five key attributes any CLE must incorporate: embedded within realistic and authentic environments, allow for communication and collaboration among and between students, teachers and mentors, allow for multiple perspectives and views to be seen and shared, promote a student's self-awareness and self-reflection, and allow the learner to be autonomous (Jonassen, 1994; Driscoll, 2005). When considering this list against technological affordances, the one technology that appears capable of fulfilling these requirements is virtual worlds (Kemp and Haycock, 2008). Designed as a developmental research study, this research validates the use of virtual worlds as a development tool when building a CLE within the K-12 environment. / Ph. D.

STEM Professional Volunteers in K-12 Competition Programs: Educator Practices and Impact on Pedagogy

Zintgraff, Alfred Clifton 12 1900 (has links)
This mixed methods dissertation study explored how secondary school educators in specific K-12 competition programs recruited and deployed STEM professional volunteers. The study explored which practices were viewed as most important, and how practices related to constructivist pedagogy, all from the viewpoint of educators. The non-positivist approach sought new knowledge without pursuing generalized results. Review of the literature uncovered extensive anecdotal information about current practices, and suggested that large investments are made in engaging volunteers. One National Science Foundation-sponsored study was identified, and its recommendations for a sustained research agenda were advanced. Three study phases were performed, one to explore practices and operationalize definitions, a second to rate practice's importance and their relation to pedagogy, and a third to seek explanations. Educators preferred recruiting local, meaning recruiting parents and former students, versus from industry or other employers. Most educators preferred volunteers with mentoring skills, and placing them in direct contact with students, versus deploying volunteers to help with behind-the-scenes tasks supporting the educator. Relationships were identified between the highest-rated practices and constructivism in programs. In STEM professional volunteers, educators see affordances, in the same way a classroom tool opens affordances. A model is proposed which shows educators considering practicality, pedagogy, knowledge and skills, and rapport when accessing the affordances opened by STEM professional volunteers. Benefits are maximized when programs align with strong industry clusters in the community.

Text production in Bebo : a study of three children's text production in online social networking sites

Dowdall, Clare A. January 2012 (has links)
This thesis aims to explore three pre-teenage children’s text production in online social networking sites. Social networking is a mainstream youth activity in the UK, conducted by (at the time of writing) almost 50% of 10-12 year old internet users (Ofcom, 2011, p.44). While social networking has been the subject of much interest amongst scholars and policy-makers, little has been published that documents the use of social networking amongst pre-teenage children. The literature that does exist is largely concerned with documenting usage (Ofcom, 2011; Livingstone and Haddon, 2010), and children’s safety in these contexts (Department for Children, Schools and Families (DCSF)/Byron 2010; DCSF/Byron, 2008; Livingstone et al., 2011a). This study aims to explore children’s text production in social networking sites with rightful regard for this concern, but with a focus on how children behave as text producers in these contexts. Working from an interpretive qualitative research paradigm, a purposive sample of three children who used (at the time) the popular social networking site Bebo was selected. The children were interviewed using a semi-structured interview schedule three times between June 2008 and May 2009. Interviews were transcribed using a line by line coding method. To support these data and contextualise analysis, screenshots of the children’s profile pages were also collected at each interview. Using a constructivist grounded theory approach (Charmaz, 2006), these data were analysed within data sets around each interview incident, and then synthesised to build a case study for each participant. This recursive process involved initial and focused coding, where following the construction of key codes for each data set, the codes were organised under thematic headings and finally used to construct tentative categories that described how the children behaved as text producers. Four tentative categories were constructed to describe the participants’ behaviour: text production to achieve social positioning; text production to achieve social control; text production to enact a text producing role; and text production for pleasure. Based upon the elaboration of these categories, a model of text production as mastery is proposed. In this model, children’s text production is regarded in relation two spectrums of mastery: a spectrum of social control and a spectrum of textual crafting. This study concludes by recommending that the social networking context must be recognised by educators as a meaningful context in which children’s mastery of these critical skills can be developed in order that they can they learn to be critical and masterful text producers in the new digital age (Gee, 2011 and Hayes, 2011).

Intercultural discourse in virtual learning environments

Dolatabadi, Hamid Reza January 2010 (has links)
The potential of community building through computer-mediated communication (CMC) in virtual learning environments has received increasing attention in recent years, yet little empirical research has been conducted in this field in Middle Eastern countries particularly based on a social constructivist approach as in this case. This research is concerned with the processes of community building as experienced by university students in computer-mediated distance education classes in Iran. Its overarching concern was to see if convergence happens in an on-line university discussion forum in a Middle Eastern cultural context, and if so, to explore how it happens and with what strategies it can be supported in such environment. The research addressed the role of collaborative interaction as the process of co-construction of knowledge and identities, by looking at: (i) the students’ beliefs as reflected in a survey; (ii) patterns and outcomes of interaction derived from an analysis of on-line transactions; (iii) students’ perspectives based on interviews and their responses to a survey. The participants came from four different Middle Eastern cultural and linguistic backgrounds and were all students studying at Masters Level. The academic context was an Iranian university that has a large face-to-face student population as well as a large number of distance students. The participants’ common meeting ground was primarily a virtual environment created for the students to share their learning experience and to communicate with each other and the tutors. The participants’ beliefs and ideas in terms of choice, opportunity, culture and expectations were examined through a survey in the first phase of the study. Then, to investigate their roles in shaping the on-line community, an additional university e-forum was designed and implemented by the researcher in the second phase of the study. In this forum the participants were free to contact each other without pre-planned tasks or interventions by the class tutors. Social constructivist approaches were used to analyse interactions between students and the outcomes of these interactions. The findings suggest that participants moved their communicative competence from tangible topics towards shaping new beliefs and ideas; creating the VSD-Virtual Social Development- model. These developments are regarded as something unique for an area such as the Middle East where gaining confidence is hard especially when there is no face-to-face contact with other participants, and individuals often have concerns about revealing their real personalities in untried situations. The findings of the interviews support the findings of the second phase of the study and show what strategies the participants used in community building. The research also highlighted many issues for further study, one of which is the various interpretations of the concept of community building in on-line contexts.

Mind the gap! : The decision making gap between the Security Council and the Troop Contributing Countries; when "all necessary means" is not enough

Abrahamsson, Zarah January 2015 (has links)
This two part thesis investigates the lack of definition of the wording “all necessary means” and how it ultimately impacts a decision making gap between the Security Council and the troop contributing countries regarding the use of force in UN peace operations. The assumptions are based on Reus-Smit’s constructivist theory, emphasizing that both politics and international law needs to be studied with a holistic approach in order to understand how the two realms shape each other. The assumption of this thesis is that “all necessary means” is not providing enough guidance to constrain the TCCs to behave as sovereign, equal actors in an anarchical structure. The second part of the thesis is a within-case-study of MONUC/MONUSCO, and the Security Council resolution 2098 that established the Force Intervention Brigade.

Processus d’adaptation des personnes vivant avec la schizophrénie et ayant un soutien social limité / Adaptation process of people with schizophrenia and with limited social support

Jacques, Marie-Claude January 2016 (has links)
Résumé : La schizophrénie est un trouble mental grave qui affecte toutes les facettes de la vie de la personne. En outre, le manque de soutien social est un problème important qui contribue à l’aggravation de la maladie, notamment en influençant négativement la capacité d’adaptation. Chez les personnes atteintes de schizophrénie, la capacité à utiliser des stratégies d’adaptation adéquates et efficaces est essentielle afin d’améliorer la santé, le bien-être et la prévention des rechutes. Cette recherche utilise la conception de l’adaptation de Roy (2009). De nombreuses études confirment la présence de difficultés d’adaptation chez ces personnes. De plus, le processus d’adaptation lui-même reste mal connu. La question de recherche était : Quel est le processus d’adaptation des personnes vivant avec la schizophrénie lorsque leur soutien social est limité ? Cette question sous-tendait deux objectifs : 1) décrire le processus d’adaptation des personnes atteintes de schizophrénie dans un contexte de soutien social limité et 2) contribuer au développement du modèle de Roy dans le contexte des troubles mentaux graves. Le devis de recherche était la théorisation ancrée constructiviste, auprès de 30 personnes vivant avec la schizophrénie. Les données étaient composées d’entrevues et de résultats de trois questionnaires qui ont contribué à décrire de façon plus détaillée le profil des participants. Les résultats sont une modélisation du processus d’adaptation nommée « les filtres dans le processus d’adaptation des personnes vivant avec la schizophrénie ». Cette modélisation met en lumière le fait que le potentiel d’adaptation des personnes vivant avec la schizophrénie est affecté à la fois par des éléments de l’environnement social et des éléments inhérents à la maladie elle-même. Ces éléments altèrent la possibilité et la capacité à utiliser des stratégies d’adaptation adéquates et efficaces. Ces résultats de recherche pourraient permettre d’améliorer l’évaluation des personnes atteintes de schizophrénie et de diminuer les « inconnues » dans l’effet des interventions, tout comme de favoriser les actions visant à lutter contre les conditions sociales qui nuisent à l’adaptation. / Abstract : Schizophrenia is a severe mental disorder that affects all human facets of life. In addition, the lack of social support is an important problem that contributes to the worsening of the disease by negatively influencing the capacity to adapt. For people with schizophrenia, ability to use appropriate and effective coping strategies is essential to improve health, well-being and preventing relapse. This research uses Roy’s adaptation model (2009). Numerous studies confirm the presence of adaptation problems for those persons. Furthermore, the adaptation process itself remains unclear. The research question was: what is the adaptation process of people with schizophrenia when social support is limited? This question underpinned two objectives: 1) describe the adaptation process of people with schizophrenia in a limited social support context and 2) contribute to the development of Roy’s adaptation model in severe mental disorders context. The research design was a constructivist grounded theory, with 30 people with schizophrenia. The data were consisted of interviews and results of three questionnaires that were helping to detail the participants profile. The results show a construct of an adaptation process called "the filters in the adaptation process of someone living with schizophrenia". This construct highlights the fact that the adaptation potential of people with schizophrenia is affected both by elements of the social environment and elements that are inherent to the disease itself. These elements affect the possibility and the ability to use appropriate and effective coping strategies. The research findings could facilitate the assessment of people with schizophrenia and reduce the unknowns in the impact of interventions, as well as fighting against social conditions that can interfere with their capacity to adapt.
