Empowering U.S. Marshallese Students to Engagement and Active Participation in Learning

Robinson, Sam J 05 1900 (has links)
The U.S. Marshallese population is one of the fastest growing Pacific Islander populations in the United States. The purpose of this study was to identify how U.S. Marshallese students could be empowered and engaged in their learning through clearly identified indicators that educators could apply within their classrooms and schools. The indicators have been established on a historical, cultural, and linked perceptions of student learning as identified by U.S. Marshallese students and teachers. Pacific Islanders consisted of a variety of populations with varying cultures and ethnic diversity. This study has been conducted using a postpositivism worldview, Marshallese migration is not a limited phenomenon of displacement, but a migratory change that must be embraced by communities and educators. Educators must understand how to empower and engage U.S. Marshallese students in their learning. This study was designed utilizing an interpretative descriptive naturalistic ethnography qualitative research design with middle school students and teachers to gather qualitative data from U.S. Marshallese students that will lead to a contextual understanding of empowering and engaging U.S. Marshallese students in their learning. The findings of this qualitative research study can be applied by educators to empower and engage U.S. Marshallese students in their learning on a daily basis in schools and classrooms. Culture understanding, positive relationship building, and the design of culturally connected intrinsically student motivated learning activities is the foundation and critical component of empowering and engaging U.S. Marshallese students in school and classrooms for improved student learning.

An exploration of school-community links in enabling environmental learning through food growing : a cross-cultural study

Köhly, Nicolette January 2010 (has links)
Agricultural and educational researchers recognize the critical value of an integrated, multidisciplinary approach to education in building a food-secure world, reducing poverty, and conserving and enhancing natural resources. However, schools generally contribute little to communities in the context of food growing and environmental learning. The main objective of this qualitative research was to explore the role of school-community relationships in enabling environmental learning in the context of food growing activities. Findings suggest that the role of school-community links in enhancing environmental learning is more likely where community members are actively involved in school programs that have an emphasis on an experiential learning approach. However, this depends to a large extent on the availability of parents or concerned community members and their willingness to engage in voluntary school-based activities. Factors that could potentially strengthen the role of school-community links in supporting environmental learning include: allowing space for informal learning, mediating learning in civil society settings, ongoing facilitation by a committed coordinator, community buy-in and accountability, and addressing public interests through tangible benefits. A major challenge is to find an appropriate balance between social justice and practical food security concerns, while remaining true to ecological considerations.

Investigating effective teaching of an online module in an Open Distance learning environment: a case study

Hlatshwayo, Vivienne 11 1900 (has links)
Text in English / In a quest to identify best practices in teaching courses in English for Specific Purposes (ESP), this study investigated effective teaching of an online English module in an Open Distance Learning (ODL) environment. Although ODL is attractive to both students and lecturers, there are significant problems regarding how learning, teaching, interaction and assessment should be conducted in this context. The problems are exacerbated by the limited knowledge of using the online systems and constraints linked to time spent on tasks. The study adopted the qualitative research approach, using a case study design and data collected from three research instruments, namely online questionnaires, an online observation schedule and a content analysis schedule. The research population in the current study comprised students, lecturers, and e-tutors based at one ODL university. In order to engender best practices of effective teaching in an ODL environment, the Community of Inquiry (Col) framework and Zone of Proximal Development (ZPD) theory were applied to the research findings of the current study. The findings indicate that effective teaching of an online English module in an ODL context could take place when content is effectively structured; assessment reflects course content; there is teamwork and collaboration amongst lecturers; students effectively interact with the material, lecturers/e-tutors, and with each other. The findings of this study add to the volume of research on best practices for effective online ESP teaching in ODL higher learning institutions. / English Studies / D. Litt. et Phil. (English)

Apport des images satellites à très haute résolution spatiale couplées à des données géographiques multi-sources pour l’analyse des espaces urbains / Contribution of very high spatial resolution satellite images combined with multi-sources geographic data to analyse urban spaces

Rougier, Simon 28 September 2016 (has links)
Les villes sont confrontées à de nombreuses problématiques environnementales. Leurs gestionnaires ont besoin d'outils et d'une bonne connaissance de leur territoire. Un objectif est de mieux comprendre comment s'articulent les trames grise et verte pour les analyser et les représenter. Il s'agit aussi de proposer une méthodologie pour cartographier la structure urbaine à l'échelle des tissus en tenant compte de ces trames. Les bases de données existantes ne cartographient pas la végétation de manière exhaustive. Ainsi la première étape est d'extraire la végétation arborée et herbacée à partir d'images satellites Pléiades par une analyse orientée-objet et une classification par apprentissage actif. Sur la base de ces classifications et de données multi-sources, la cartographie des tissus se base sur une démarche d'extraction de connaissances à partir d'indicateurs issus de l'urbanisme et de l'écologie du paysage. Cette méthodologie est construite sur Strasbourg puis appliquée à Rennes. / Climate change presents cities with significant environmental challenges. Urban planners need decision-making tools and a better knowledge of their territory. One objective is to better understand the link between the grey and the green infrastructures in order to analyse and represent them. The second objective is to propose a methodology to map the urban structure at urban fabric scale taking into account the grey and green infrastructures. In current databases, vegetation is not mapped in an exhaustive way. Therefore the first step is to extract tree and grass vegetation using Pléiades satellite images using an object-based image analysis and an active learning classification. Based on those classifications and multi-sources data, an approach based on knowledge discovery in databases is proposed. It is focused on set of indicators mostly coming from urbanism and landscape ecology. The methodology is built on Strasbourg and applied on Rennes to validate and check its reproducibility.

Improving Student Interest, Mathematical Skills, and Future Success through Implementation of Novel Mathematics Bridge Course for High School Seniors and Post-secondary Students

Webb, Derek, Richgels, Glen, Wolf, Marty J., Frauenholtz, Todd, Hougen, Ann 11 May 2012 (has links) (PDF)
We present a new course titled “Introduction to the Mathematical Sciences.” The course content is 1/3 algebra, 1/3 statistics, and 1/3 computer science and is taught in a laboratory environment on computers. The course pedagogy departs radically from traditional mathematics courses taught in the U.S. and makes extensive use of spreadsheet software to teach algebraic and statistical concepts. The course is currently offered in area high schools and two-year postsecondary institutions with financial support from a Blandin Foundation grant (referenced under BFG). We will present empirical evidence that indicates students in this course learn more algebra than students in a traditional semester-long algebra course. Additionally, we present empirical evidence that students learn statistical and computer science topics in addition to algebra. We will also present the model of developing this course which depended on increasing future student success in a variety of disciplines at the post-secondary level of study.

Action competence and waste management: a case study of learner agency in two Grahamstown eco-schools / Probing the development of action competence amongst learners participating in school waste management activities : a case of two Grahamstown schools

Chiphwanya, Nellie Chimwemwe January 2011 (has links)
There has been a growing need in environmental education to develop students' ability and will to take part in democratic processes that enable them take environmental action in their local environment. This study examined learner action competence in waste management practices in two primary school contexts in the Eastern Cape, South Africa. An interpretive case study design is used to probe how learner participation in Eco-School waste management practices enabled the acquisition of knowledge in purposeful learning and action experiences that developed the vision and agency of informed action. The research was centred on two guiding questions: 1. How informed, purposeful and action-orientated is learner participation in Eco-School waste management activities? 2. What Eco-School waste management activities are fostering active participation towards a learner-led agency? Educators in the two schools were interviewed and Eco-School portfolios were examined for evidence of the learning activities and learner achievement. This provided the contextual data for reviewing focus group interviews to probe what was significant to learners, what they came to know and how they had contributed to the process of developing better waste management in the Eco-School context. The evidence generated in the study was used to identify the roles of the various players, the significant activities and processes that enabled and constrained the emergence of learner-led agency. The main findings in the study were that teacher intentionality and school management ethos were significant in engaging learners in meaningful waste management activities in both cases. The study also revealed that although most of the waste management activities in both cases were teacher-initiated, there were spaces open for learner initiatives. However, it appeared that the activity based waste management practices mostly allowed learners to learn how to do waste management more than allowing them to find out more about the scope and nature of ii the problem of waste. This then resulted in learners talking more about what they were doing with waste than talking about what they knew about waste. There were differences in the way in which learners approached waste in the two cases. In the one case, Kingswood Junior School learners used waste artistically and carried out activities that allowed for better use of waste resources like paper while in the other School, Grahamstown SDA School, learners approached waste as a resource for making money. However, in both cases, learners appeared to enjoy the positive experiences of doing things that contributed to a cleaner environment and were of benefit to others and this gave them a sense of pride to share their experiences with others. This study was significant as it allowed me to probe learner participation and examine the development of their action competence through listening to the voices of the learners themselves and understanding what was important to them about the knowledge they gained and their vision of better waste management.

Exploring opportunities for action competence development through learners' participation in waste management activities in selected primary schools in Botswana

Silo, Nthalivi January 2011 (has links)
The broader aim of this study is to probe participation of learners in waste management activities in selected primary schools in Botswana and through these activities, explore opportunities for action competence development. The study starts by tracing and outlining the socio-ecological challenges that confront children and the historical background of learner-centred education which gave rise to an emphasis on learner participation in Botswana education policy. It then maps out the development of children's participation in the global, regional and Botswana contexts by tracing the development of environmental education from early ecological and issue resolution goals of environmental education to sustainable development discourses. The focus is on policy issues and how learner participation has been represented and implemented in environmental education. The study then probes the rhetorical and normalised emphases on participation, and seeks further insight into how learners can be engaged in participatory learning processes that are meaningful, purposeful and that broaden their action competence and civic agency. The study uses the Cultural Historical Activity Theory (CHAT) methodology to build a picture of waste management activity systems in primary schools and to bring to the surface contradictions and tensions in learner participation in these activity systems. These contradictions are used to open up expansive learning participatory processes with learners using the Danish action competence framework. The expansive learning process uses action competence models that provide potential for transformative participation with learners, and new and different opportunities for learner participation. Case study research was used and conducted in the south eastern region of Botswana in three primary schools in three contexts, namely urban, peri-urban and rural. The data was largely generated through focus group interviews during workshops with children and observations of waste management activities. These two methods formed the main data generation methods. They were complemented by semi-structured interviews with teachers, and other actors in the waste management activities, learners' activities and work, learners' notes, photographs and children's drawings as well as show-and-tell explanations by learners. Content analysis and the abductive mode of inference were used to analyse data in all three case studies. Findings from the first phase of the study reveal that participation of learners in waste management activities was largely teacher-directed. This resulted in a mis-match between teachers views of what practices are necessary and important, and children's views of what practices are necessary and important in and for environmental education. Due to culturally and historically formed views of environmental education, the study reveals that teachers wanted children to pick up litter, and this was their primary environmental education concern. Learners on the other hand, identified sanitation management in the school toilets as their primary waste management concern. Teachers had not considered this an environmental education concern. Using the action competence expansive learning approach, the second phase of the study addressed this tension by opening up dialogue between teachers and learners and amongst the learners themselves through an expansive learning process supporting children's participation and action competence development. Through this teacher-learner dialogical engagement, a broader range of possibilities became available and ideas around participation were radically changed. The study further reveals that the achievement of this open dialogue provided for a better relationship within the school community. And with improved communication came better ideas to solve waste management issues that the community still face on a daily basis, such as too much litter. Newly devised solutions were practical and had a broader impact than the initial ones that teachers had always focussed on. They included mobilising the maintenance of toilets, landscaping the school premises and even re-contextualising the litter management that had always caused tensions between learners and teachers. Children seemed to be developing not only a better understanding of the environment, but also developing the ability to resolve conflict amongst themselves and with their elders. By engaging in dialogue with children, they became co-catalysts for change in the school community. This study shows that if children's participation is taken seriously, and if opportunities for dialogue exist between teachers and children, positive changes for a healthier environment can be created in schools. It reveals that children also appeared to be feeling more confident and more equipped to consider changes in their environment outside of the school community. The study further shows that participation in environmental education involves more than cognitive changes as proposed in earlier constructivist literature; it includes in-depth engagement with socio-cultural dynamics and histories in the school context, such as the cultural histories of teachers, schooling and authority structures in the cultural community of the school. The study recommends that there is need to strengthen Teacher Education programmes to develop teaching practices and support for teachers to identify ways of engaging learners' views on issues in the school in open, dialogical ways. Such Teacher Education programmes should deepen teachers' understandings of learners' zone of proximal development (ZPD), demonstrating how dialogue and scaffolding are part of a teacher's role in supporting learning. This is shown in the three case studies that form part of this study. Finally, the study also deepens insights of using the Cultural Historical Activity theory (CHAT) to shed light on issues surrounding learner participation within the socio-cultural and historical environmental education contexts of the schools. The action competence models used in the study provide a tool for revealing forms of learner participation. This tool can be used for critical reflections and monitoring of teaching practices in schools.

Examining emergent active learning processes as transformative praxis : the case of the schools and sustainability professional development programme

Schudel, Ingrid Joan 20 September 2013 (has links)
This is a study on the nature of learning, particularly the emergence of active learning processes in the case of an environmental education teacher professional development programme – the Eastern Cape Border-Kei cohort of the 2008 Schools and Sustainability Course. This was a part-time, one-year course supporting teachers to qualify, strengthen and deepen opportunities for environmental learning in the South African curriculum. An active learning framework (O’Donoghue, 2001) promoting teaching and learning with information, enquiry, action and reporting/reflection dimensions was integrated into the Schools and Sustainability course design to support these environmental learning opportunities. In this study, the notion of active learning is elaborated as a situated, action-oriented, deliberative and co-engaged approach to teaching and learning, and related to Bhaskar’s (1993) notion of transformative praxis. The study used a nested case study design, considering the case of six Foundation Phase teachers in six primary schools within the Border-Kei Schools and Sustainability cohort. Interviews, observations (of workshops and lesson plan implementation in classrooms) and document review of teacher portfolios (detailing course activities, lesson plans, learners’ work and learning and teaching support materials) were used to generate the bulk of the data. A critical realist theory underpinning the methodology enables a view of agency as emergent from social structures and mechanisms as elaborated in Archer’s (1998b) model of morphogenesis and Bhaskar’s (1993) model of four-planar being. The critical realist methodology also enables a view of emergent active learning processes as open-ended, responsive to particular potential, but dependent on contingencies (such as learning and teaching support materials, tools and methodologies). The analysis of emergent active learning processes focuses particularly on Bhaskar’s (1993) ontological-axiological chain (MELD schema) as a tool for analysing change. The MELD schema highlights1M ontological questions of what is (with emphasis on structures and generative mechanisms) and what could be (real, but non-actualised possibilities). It enables reflection on what mediating and interactive agential processes either reproduce what is or have the potential to transform what is to what could be (2E). Thirdly, the MELD schema enables reflection on what should be – this is the 3L “axiological moment” (Bhaskar, 1993: 9) where questions of values and ethics in relation to the holistic whole are raised. Finally, the schema raises questions (4D) of what can be, with ontologically grounded, context-sensitive and expressively veracious considerations. The study describes the agency of course tutors, teachers and learners involved in the Schools and Sustainability course, as emergent from a social-ecological context of poverty and inequality, and from an education system with a dual transformative and progressive intent (Taylor, 1999). It uses a spiral approach to cluster-based teacher professional development (Janse van Rensburg & Mhoney, 2000) focusing on the development of autonomous (Bernstein, 1990) and reflexive teachers. With teachers well-disposed and qualified to fill a variety of roles in the classroom, these generative structures and mechanisms had the power to drive active learning processes with potential for manifestation as transformative praxis. Through the analysis of the active learning processes emergent from this context, the study shows that the manifestation of transformative praxis was contingent on relational situated learning, value-based reflexive deliberations, and an action-orientation with an emphasis on an iterative relationship between learning and doing. These findings enable a reframing of an interest in action in response to environmental issue and risk, to an interest in the processes that led up to that action. This provides a nuanced vision of active learning that does not judge an educational process by its outcome. Instead, it can be judged by the depth of the insights into absences (2E), the ability to guide moral deliberations on totality (3L), and by the degree of reality congruence (1M) in the lead up to the development of transformative agency (4D). The study also has a methodological interest. It contributes to educational and social science research in that it applies dialectical critical realist philosophy to a concrete context of active learning enquiry in environmental education. It reports on the value of the onto-axiolgical chain in describing a diachronic, emergent and open-ended process; in providing ontological grounding for analysis (1M); in understanding relationality in situated learing processes (2E); in focusing on value-based reflexive learning (3L) and in understanding transformative learning as “tensed socio-spatialising process” (Bhaskar, 1993: 160) where society is emergent from a stratified ontology, and agency and change are open-ended and flexible processes not wholly determined by the social structures from which they emerge (4D). Considering the knowledge interests defined in the 2011 South African Minimum Requirements for Teacher Education (South Africa. Department of Higher Education and Training, 2011) and the Curriculum Assessment Policy Statements (CAPS) which were implemented in South Africa from 2012 (in a phased approach), the study concludes with recommendations for exploring environmental learning in the CAPS. The study proposes working with a knowledge-focused curriculum focusing on the exploration and deepening of foundational environmental concepts, developing relational situated learning processes for meaningful local application of knowledge, supporting transformative praxis through the “unity of theory and practice in practice” (Bhaskar, 1993: 9), and implementing a spiral approach to cluster-based teacher professional development.
