    This embedded quasi-experimental research design examined the impact of an enrichment initiative entitled the Mathematics Enhancement Programme (MEP) on Jamaican students’ performance and attitude towards mathematics. It identified teaching strategies for integrating the MEP into Jamaican primary mathematics classes. It investigated the impact of the MEP on teachers’ pedagogical practices, and it identified the barriers to integrating the MEP. A sample of 331 students and 12 teachers were conveniently selected from three schools from three parishes in Jamaica for the intervention group. The comparison group consisted of 180 students and seven teachers conveniently selected from two schools in central Jamaica. The participating teachers were trained and certified in a mathematics Subject Knowledge Enhancement (SKE) programme prior the implementation of the MEP. The treatment involved teaching the Jamaican grades one and two mathematics standards using the MEP resources for nine months. Quantitative data collection over the school year included pre-tests, post-tests, and pre- and post- children’s mathematics attitudinal surveys. The qualitative data was obtained through classroom observations and interviews. The quantitative data was analysed by means of descriptive statistics which involved the use of the 25th version of the statistical software (SPSS). Descriptive and in vivo coding were used to analyse the qualitative data which involved the use of QRS international’s NVivo 12 qualitative software programme. A statistically significant impact and large effect size of the intervention was found, indicating that the MEP had a substantial impact on students’ achievement and attitudes towards mathematics. Additionally, numerous teaching strategies were found to be effective for integrating the MEP. The findings also indicated there are aspects of the MEP that participating teachers thought were worth adapting and implementing in their practices. It was also found that there are barriers to integrating the MEP into Jamaican primary mathematics classrooms. Implications for designing enrichment programmes geared at addressing mathematics underperformance in Jamaica and other countries are discussed

    Chinese Knitwear Brands: The need for creative design to result in global business success

    Get PDF
    Chinese cashmere knitwear companies have become suppliers of international fashion brands because of their technological excellence, advantages of raw materials and competitive prices. However, their in-house brands are steadily declining. In the past 15 years, Chinese cashmere brands have progressively lost their market share to Chinese and Western fashion brands, with a few notable exceptions. Their brands lack differentiation from other Chinese competitors, causing low price competition, which contributes to sustainability issues such as unsold stock and material/manpower waste. The decline is likely to continue as the brands serve only an ageing market, rather than attracting younger generations to their products. Chinese cashmere companies invest little in design, which is a significant limitation for improving the brands’ opportunity to become successful and sustainable businesses. This study looks for solutions from the design perspective. The research aimed to investigate what design can do to help deal with the current problems of the Chinese knitwear brands to improve their prospects for future business success. The objectives of the study were to enquire into the challenges and opportunities facing the Chinese knitwear sector, to evaluate current design practice in knitwear brands, to understand how design and brand management can be integrated to generate a sustainable brand. Research questions were developed to explore the brand and design problems, the role of design and organisational structure, what the barriers and enablers for a thriving design culture were alongside possible solutions for design improvement. A pragmatic philosophy underpinned research design, guiding the adoption of methods in response to research questions. Interviews with stakeholders from both the knitwear industry and design education were undertaken. In addition, a case study using design action research with immersive field research was developed for investigating the knitwear brand issues; furthermore, a knitwear collection was created using western design approaches to demonstrate an exemplar design process for the sector and to illustrate the differences to current Chinese design methods. The study argues the obstacles to design culture enrichment in Chinese knitwear brands was caused by their design context, lack of brand positioning, limited understanding of their consumers and business models that are not fit for purpose. An absence of experienced leadership creates unclear design direction, instead of collections centred around a theme; Chinese brands sell unconnected designs. Brands lack the distinct brand characteristics that distinguish them from their competitors. The contribution to knowledge made by this study includes the identification of the reasons for the decline in Chinese cashmere brands, an understanding of their barriers to design culture to developing good designs and it also highlights the lack of awareness of sustainability issues in the sector. The study sheds new light on the rarely acknowledged issue of how to upgrade these brands as modern business for younger consumers, and how to enrich the design culture for brand business growth within sustainable contexts. The thesis analyses in depth the causes for the decline in these brands and makes recommendations for how design can make a contribution to reversing the brands’ decline and increasing their sustainability

    Archaeological palaeoenvironmental archives: challenges and potential

    Get PDF
    This Arts and Humanities Research Council (AHRC) sponsored collaborative doctoral project represents one of the most significant efforts to collate quantitative and qualitative data that can elucidate practices related to archaeological palaeoenvironmental archiving in England. The research has revealed that archived palaeoenvironmental remains are valuable resources for archaeological research and can clarify subjects that include the adoption and importation of exotic species, plant and insect invasion, human health and diet, and plant and animal husbandry practices. In addition to scientific research, archived palaeoenvironmental remains can provide evidence-based narratives of human resilience and climate change and offer evidence of the scientific process, making them ideal resources for public science engagement. These areas of potential have been realised at an imperative time; given that waterlogged palaeoenvironmental remains at significant sites such as Star Carr, Must Farm, and Flag Fen, archaeological deposits in towns and cities are at risk of decay due to climate change-related factors, and unsustainable agricultural practices. Innovative approaches to collecting and archiving palaeoenvironmental remains and maintaining existing archives will permit the creation of an accessible and thorough national resource that can service archaeologists and researchers in the related fields of biology and natural history. Furthermore, a concerted effort to recognise absences in archaeological archives, matched by an effort to supply these deficiencies, can produce a resource that can contribute to an enduring geographical and temporal record of England's biodiversity, which can be used in perpetuity in the face of diminishing archaeological and contemporary natural resources. To realise these opportunities, particular challenges must be overcome. The most prominent of these include inconsistent collection policies resulting from pressures associated with shortages in storage capacity and declining specialist knowledge in museums and repositories combined with variable curation practices. Many of these challenges can be resolved by developing a dedicated storage facility that can focus on the ongoing conservation and curation of palaeoenvironmental remains. Combined with an OASIS + module designed to handle and disseminate data pertaining to palaeoenvironmental archives, remains would be findable, accessible, and interoperable with biological archives and collections worldwide. Providing a national centre for curating palaeoenvironmental remains and a dedicated digital repository will require significant funding. Funding sources could be identified through collaboration with other disciplines. If sufficient funding cannot be identified, options that would require less financial investment, such as high-level archive audits and the production of guidance documents, will be able to assist all stakeholders with the improved curation, management, and promotion of the archived resource

    What effect does short term Study Abroad (SA) have on learners’ vocabulary knowledge?

    This thesis describes a study which tracks longitudinal changes in vocabularyknowledge during a short-term Study Abroad (SA) experience. A test ofproductive vocabulary knowledge, Lex30 (Meara & Fitzpatrick, 2000),requiring the production of word association responses, is used to elicit vocabulary from 38 Japanese L1 learners of English at four test times at equal intervals before and after an SA experience. The study starts by investigating whether there are changes in both the total number of words and in the number of less frequently occurring words produced by SA participants. Three additional ways of measuring the development of lexical knowledge over time are then proposed. The first examines changes in the ability of participants of different proficiency levels in producing collocates in response to Lex30 cue words. The second tracks changes in spelling accuracy to measure if improvements take place over time. The third analysis uses an online measuring instrument (Wmatrix; Rayson, 2009) to explore if there are any changes in the mastery of specific semantic domains. The results show that there is significant growth in the productive use of less frequent vocabulary knowledge during the SA period. There is also an increase in collocation production with lower proficiency participants and evidence of some improvement in the way certain vocabulary items are spelled. The tendency for SA learners to produce more words from semantic groups related to SA experiences is also demonstrated. Post-SA tests show that while some knowledge attrition occurs it does not decline to pre-SA levels. The studyshows how short-term SA programmes can be evaluated using a word association test, contributing to a better understanding of how vocabularydevelops during intensive language learning experiences. It also demonstrates the gradual shift of productive vocabulary knowledge from partial word knowledge to a more complete state of productive mastery

    Get PDF
    This ïŹfth volume on Advances and Applications of DSmT for Information Fusion collects theoretical and applied contributions of researchers working in different ïŹelds of applications and in mathematics, and is available in open-access. The collected contributions of this volume have either been published or presented after disseminating the fourth volume in 2015 in international conferences, seminars, workshops and journals, or they are new. The contributions of each part of this volume are chronologically ordered. First Part of this book presents some theoretical advances on DSmT, dealing mainly with modiïŹed Proportional ConïŹ‚ict Redistribution Rules (PCR) of combination with degree of intersection, coarsening techniques, interval calculus for PCR thanks to set inversion via interval analysis (SIVIA), rough set classiïŹers, canonical decomposition of dichotomous belief functions, fast PCR fusion, fast inter-criteria analysis with PCR, and improved PCR5 and PCR6 rules preserving the (quasi-)neutrality of (quasi-)vacuous belief assignment in the fusion of sources of evidence with their Matlab codes. Because more applications of DSmT have emerged in the past years since the apparition of the fourth book of DSmT in 2015, the second part of this volume is about selected applications of DSmT mainly in building change detection, object recognition, quality of data association in tracking, perception in robotics, risk assessment for torrent protection and multi-criteria decision-making, multi-modal image fusion, coarsening techniques, recommender system, levee characterization and assessment, human heading perception, trust assessment, robotics, biometrics, failure detection, GPS systems, inter-criteria analysis, group decision, human activity recognition, storm prediction, data association for autonomous vehicles, identiïŹcation of maritime vessels, fusion of support vector machines (SVM), Silx-Furtif RUST code library for information fusion including PCR rules, and network for ship classiïŹcation. Finally, the third part presents interesting contributions related to belief functions in general published or presented along the years since 2015. These contributions are related with decision-making under uncertainty, belief approximations, probability transformations, new distances between belief functions, non-classical multi-criteria decision-making problems with belief functions, generalization of Bayes theorem, image processing, data association, entropy and cross-entropy measures, fuzzy evidence numbers, negator of belief mass, human activity recognition, information fusion for breast cancer therapy, imbalanced data classiïŹcation, and hybrid techniques mixing deep learning with belief functions as well

    Thematic Working Group 3 - Inclusion of Excluded Populations : Access and Learning Optimization via IT in the Post-Pandemic Era

    Get PDF
    Thematic Working Group (TWG) 3’s theme is “Inclusion of excluded populations: access and learning optimization via IT in the post-pandemic era”. A focal concern is established by the presence of the first word – ‘inclusion’ – and how this relates to ‘excluded populations’. Much of the research in this field has focused on inclusion for individuals; however, the evidence shows that educational exclusion has multiple dimensions (Passey, 2014). To accommodate this within the current focus, therefore, identifying key dimensions of ‘excluded populations’ will be a key concern of this document. ‘Access’ will be considered beyond physical technology access, involving aspects of accessibility, agency and empowerment. These aspects relate to a definition of access that concerns the needs for individuals to develop and have digital capabilities and abilities to select applications appropriate to purpose, as discussed, for example, by Helsper (2021) and Passey et al. (2018). Taking this wider concern for access, ‘learning optimization’ will be explored as a term that highlights the need to focus on technological access and provision enabling successful outcomes. Given the fact that the intention of the work of TWG3 is to explore findings in the ‘post-pandemic’ context, communication technologies as well as just information technology, ‘IT’, are clearly important and need to be considered. Additionally, exclusion factors to be addressed need to be clearly identified so that inclusion can be accommodated and ensured in the context of specific excluded populations. However, inclusion should not be implemented as an imposition in the context of digital technologies, as some populations do not wish to use digital technologies (Wetmore, 2007), and in this respect the issue of the need to acknowledge diversity is important

    Pre-service practicum at a teacher education college : a case in Ethiopia

    Get PDF
    This study explored how the basic ideas of the constructivist theory of learning are put into practice in the pre-service practicum programme to determine the extent to which key participants hold a shared set of beliefs about the pre-service practicum and to explore its implementation at the Hossana College of Teacher Education, Ethiopia, in light of the constructivist paradigm. A single qualitative case (holistic) design was used to fully grasp the phenomenon under inquiry from the standpoint of the research participants. This qualitative single-case study was guided by the constructivist theory of learning based on constructivist interpretivism's philosophical paradigms. This research was also based on the Vygotskian epistemological idea that social reality is formed and mediated because contact and engagement do not exist without participants. Twenty-nine individuals were purposively sampled, all of whom were well-informed. Interviews, observations, document reviews, and field studies were also used to collect relevant and sufficient data for the study. The qualitative data underwent interpretive and reflective analyses. The study's findings revealed that, despite the inherent constraints of the practicum implementation process, the practicum is critical to developing competent professionals. However, it appears that the essence of the practicum is not well understood in light of the constructivist teacher education framework. Thus, participants' ideas regarding the fundamental assumptions and theoretical underpinnings of constructivist pedagogy were contradictory to the beliefs of the constructivist theory of learning. The programme was being run in an environment that did not support the ways in which to achieve the end goal. An integrated and dependable partnership or collaboration among the involved parties had not yet been established. The roles and responsibilities were not properly shared by all the concerned bodies. It seemed that a kind of compliance dominated the scene of the practicum rather than collaboration. Tasks in practicum courses were not clear and well-organised in the practicum setting, and college supervisors and cooperating teachers continued to play traditional roles. The entire learning environment is less supportive of the practicum's premises. Based on theory, policy, and practice, this study came to a conclusion on the proposed framework for pre-service practicum implementation.Curriculum and Instructional StudiesPh. D.
