數位學習產品之產品特性對消費者知覺及產品滿意度之研究-以階梯數位學院為例

張誌銘 January 1994 (has links)
數位內容產業的五個核心子產業中,數位學習產業是台灣具有相對較佳全球競爭力的領域。本研究從購買者的角度出發,引用科技接受模式(TAM) ,建構消費性數位學習產品之產品特性如何影響產品購買者之知覺及產品滿意度的評估模式,並進一步根據研究結果對業者提出具體建議。 本研究透過文獻瞭解影響數位學習產品購買者滿意度的產品特性及變數間之路徑關係,進而發展研究問卷;以大台北地區之購買者為樣本進行問卷調查;應用敘述性統計、路徑分析及單因子變異數分析等統計方法及問卷調查所得資料進行分析與推論。 根據有效樣本的歸納結果發現,購買者以36~40歲、大專學歷、從商、家庭每月總收入約8萬至12萬間者為多。顯示此產品的購買者主要以小康家庭的父母為主。 由路徑分析結果可知,數位學習產品的三項重要特性當中,產品互動性是影響產品滿意度之最重要因素,內容豐富性次之,產品便利性又次之。反應出購買者最重視數位學習產品是否能夠有效做到介面互動、教材互動與人際互動。此外,購買者亦相當重視產品內容能否幫助購買者減輕經濟負擔及教改一綱多本所導致的困擾。 路徑分析結果亦揭露了購買者對數位學習產品的知覺有用性較知覺易用性對產品滿意度有更大的影響;因此,業者在媒體行銷策略之重點上,仍難免如傳統補教業者訴諸見證的廣宣手法;此外,業者也應進一歩進行數位學習學習與認知之基礎研究,實質探討如何有效提升購買者之知覺有用性。 由單因子變異數分析結果可知,購買者的背景差異會影響其產品滿意度。因此,業者可以在市場區隔、產品組合、定價方式等政策執行面上考量更有彈性做法;並根據顧客資料,重點加強客服作業,彌補業務通路體系之不足,以建立更佳的產品口碑。 / In five nucleus sub- industries of the digital content industry, the e-learning industry is the realm that Taiwan has an opposite global competitive advantage. This study bases on the angle of purchaser, quotes from the Technology Acceptance Model (TAM), tries to construct a valuation model to study how characteristics of e-learning products could influence the consciousness and the product satisfaction of the purchaser. Furthermore, this study will make suggestions to the suppliers according to the statistical analysis. We develop a questionnaire after recognizing the path relations between the variables and the characteristics (convenience, interaction, content abundance) which influence the e-learning product satisfaction through the previous studies. Then carry on analysis and inferences by applying convenience sampling, description statistical analysis, path analysis, and single factor variation analysis etc. According to the valid samples, it induces that middle-class families are the mainly purchaser group of ladder100. And by the path analysis, the results show that the interaction is the most important of three factors which influence the e-learning product satisfaction, and then sequentially the content abundance and the product convenience. The path analysis also reveals that purchasers’ perceived usefulness has greater influence to the e-learning product satisfaction than purchasers’ perceived ease –of –use. By single factor variation analysis, we know that purchasers’ different back ground will influence their product satisfaction. / 第一章 緒論 1 第一節 研究背景 1 第二節 研究動機 5 第三節 研究目的 6 第二章 文獻探討 7 第一節 數位學習 7 第二節 數位學習產業之現況 12 第三節 階梯數位學院 14 第四節 科技接受模型理論 18 第五節 外部變數推導 23 第六節 消費者滿意度 30 第三章 研究方法 34 第一節 研究架構及研究假說 34 第二節 研究變數之操作性定義 40 第三節 問卷設計與調查過程 43 第四節 統計分析方法 45 第四章 研究結果與分析 47 第一節 樣本基本資料分析 47 第二節 信度分析 51 第三節 假說檢定之路徑分析 53 第四節 單因子變異數分析 62 第五章 結論與建議 75 第一節 結論與建議 75 第二節 研究限制與後續研究建議 80 參考文獻 82 中文文獻 82 英文文獻 84 附件 正式問卷 88 表目錄 表2.3.1 階梯數位學院線上課程分類 16 表3.2.1 學習便利性衡量題項 40 表3.2.2 學習互動性衡量題項 40 表3.2.3 內容豐富性衡量題項 41 表3.2.4 知覺易用性衡量題項 41 表3.2.5 知覺有用性衡量題項 42 表3.2.6 產品滿意度衡量題項 42 表4.1.1 樣本基本資料表 48 表4.2.1 數位學習產品購買者滿意度調查表之信度分析結果 51 表4.3.1 因果關係影響路徑及效果分類表 54 表4.3.2 模式總檢定結果摘要表 55 表4.3.3 路徑分析邊際檢定結果摘要表 59 表4.3.4 本研究之假說檢定結果彙整表 56 表4.3.5 路徑分析各項效果總表 58 表4.4.1 性別對各構面之獨立樣本T檢定結果 62 表4.4.2 年齡對各變項之單因子變異數分析總檢定結果 63 表4.4.3 年齡對產品滿意度之單因子變異數邊際檢定結果 64 表4.4.4 職業對各變項之單因子變異數分析總檢定結果 64 表4.4.5 職業對各構面之單因子變異數邊際檢定結果 65 表4.4.6 教育程度對各變項之單因子變異數分析總檢定結果 67 表4.4.7 教育程度對各構面之單因子變異數邊際檢定結果 68 表4.4.8 家庭總收入對各變項之單因子變異數分析總檢定結果 70 表4.4.9 教育程度對各構面之單因子變異數邊際檢定結果 71 表4.4.10 小孩數對各變項之單因子變異數分析總檢定結果 73 表4.4.11 家庭小孩數對知覺有用性之單因子變異數邊際檢定結果 74 圖目錄 圖2.3.1 理性行為理論 18 圖2.3.2 科技接受模式 20 圖3.3.1 研究架構 35 圖4.3.1 路徑分析邊際檢定結果 56

應用網路推廣創新醫療技術-以非營利組織口腔雷射醫學會個案為例 / The promotion of an innovative medical technology through Websites-A case study of the NPO Website of Taiwan academy of laser in dentistry (TALD)

林紋瑜, Lin, Wen Yu Unknown Date (has links)
Web2.0的盛行改變了目前網路資訊傳播方式,民眾對網路資訊擴散參與度也日益增加及重要,電子醫學網站肩負健康衛教資訊及新技術推廣的重責,如何利用Web2.0的特性,讓民眾可以輕易、適時、適所獲得相關醫學資訊是所有醫學網站所要研究的課題。因此除了如何提供質優量多且可信度、專業性高的醫療資訊外,醫學網站更要研究並了解民眾的實際需求期望及最易接受的資訊管道方式,使得相關資訊能無礙地傳送到民眾面前。本研究即以個案研究的方式,來探討如何藉由Web 2.0網路資訊平台及資訊管道設計概念,利用創新擴散策略思考及方法來推廣相關新醫療科技,使非營利組織也能像其他電子商務網站的經營方式一樣,與使用者建立價值共創的關係;並繼續延伸探討後續推廣策略建議,以提供相關網站經營參考。 本研究選定中華民國口腔雷射醫學會網站,作為本研究的個案網站,不同於一般醫學會網站的社群經營,都是以傳統單向的型錄式資訊提供方式為主,缺乏互動性及使用者導向設計。本研究的個案網站卻是集合所有專業會員醫師之群力,將民眾所需要的臨床案例、口腔新聞、醫療知識和新知、線上諮詢功能及院所指南等,加以整合,讓民眾可以藉由簡單的資訊搜尋引擎方式來找到相關完整資訊,創造出新的經營模式。本研究即藉由問卷及深度訪談,分析網路使用民眾對個案的知識創新推廣模式的接受度,並以此為基礎,研究歸納出可行的網站經營建議方案,作為個案網站在未來的經營方向之參考。 / The popularity of the concept of Web 2.0 has altered the ways information transmitted, and increases the importance of the participation of internet users on disseminating information. Electronic-health websites (e-health websites) have great responsibility of promoting the public health education and new medical technologies and treatments to the public. It is an important task for these websites applying the concept of web 2.0 to provide the public the easy and timely access to relevant information. In addition, e-health websites should also offer trustworthy and professional health information to meet the expectation of the users. In this study we use a case study to examine how to apply Technology Acceptance Model (TAM) and the concept of web 2.0 to understand the promotion of the new medical technologies and treatments. The results will help Non-Profit Organization (NPO) to transform to a highly efficient information exchanging platform and also to establish the relationship of value co-creation website. Our case website is the Taiwan Academy of Laser in Dentistry (TALD) that is different from other medical websites using traditional approach of providing static information (Web 1.0). This website is interactive and user-oriented by integrating the medical cases from dentists, latest medical news, most recent medical breakthrough, functions of searching the nearest dentists, introductions of dental clinics, and son on. This new model allows the regular users to find the relevant information in a timely manner. By survey and in-depth interviews, we are able to analyze the users’ behavior and provide recommendations for management to improve its performance.

Práticas escolares mediadas pela wiki do moodle: análise de aceitação e percepções dos estudantes / Wiki do moodle's school practices: acceptance analysis and perceptions of students

Zanini, Alessandra da Silva 30 November 2016 (has links)
The current scenario of education uses numerous technological tools to mediate and streamline teachinglearning processes. One of these tools, which has been gaining more space each day, are the collaborative production tools. The wiki tool, which belongs to the Moodle platform, for example, gives students of both face-to-face and non-face-to-face courses a collaborative and dynamic form of production. However, when presented to students, this tool, as occurs whenever we have contact with something new, causes different perceptions. This dissertation aims to verify cognitive processes regarding the use of the Moodle wiki and through the Technology Acceptance Model (TAM 3) to verify the acceptance of the same by students and alumni. As well as, list the factors that can generate lack of motivation and lack of participation in the proposed activities and, in this way, help in planning activities of more effective studies in Virtual Environments of Teaching-Learning and that mobilize the students to participate more actively . The research was carried out with a group of the Special Program of Graduation (PEG) Training of Professors for Professional Education of the UFSM, in addition to a group of PEG alumni. The choice of the participants was motivated by the fact that we believe it is important to know the perceptions, acceptance, and consequent motivation of future teachers in using the Moodle wiki. The results obtained in the TAM 3 adapted questionnaire show that the level of the average acceptance of the research participants is considered to be Moderate High. Their perceptions about the Wiki tool have provided data that confirm and validate the application of the questionnaire and elucidate the research objectives. / O cenário atual da educação utiliza inúmeras ferramentas tecnológicas para mediar e agilizar processos de ensino-aprendizagem. Uma destas ferramentas, que vem ganhando mais espaço a cada dia, são as ferramentas de produção colaborativa. A ferramenta wiki, pertencente a plataforma Moodle, por exemplo, proporciona aos estudantes dos cursos presenciais e não presenciais uma forma de produção colaborativa e dinâmica. Porém, quando apresentada aos estudantes, esta ferramenta, como ocorre sempre que temos contato com algo novo, provoca diferentes percepções. Esta dissertação tem como objetivo verificar processos cognitivos referentes a utilização da wiki do Moodle e através do modelo de aceitação tecnológica (Technology Acceptance Model-TAM 3) verificar a aceitação da mesma pelos estudantes e egressos. Assim como, elencar os fatores que podem gerar falta de motivação e falta de participação nas atividades propostas e, desta forma auxiliar no planejamento de atividades de estudos mais eficazes em Ambientes Virtuais de Ensino-Aprendizagem e que mobilizem os estudantes a participarem de forma mais ativa. A pesquisa foi realizada com uma turma do Programa Especial de Graduação (PEG) Formação de Professores para a Educação Profissional da UFSM, além de um grupo de alunos egressos do PEG. A escolha dos participantes foi motivada pelo fato de acreditarmos ser importante conhecer as percepções, a aceitação, e consequente motivação, de futuros professores em utilizar a wiki do Moodle. Os resultados obtidos no questionário adaptado TAM 3 mostram que o nível da média de aceitação dos participantes da pesquisa é considerado como Moderado Alto. As percepções dos mesmos acerca da ferramenta Wiki elencaram dados que confirmam e validam a aplicação do questionário, além de elucidarem os objetivos da pesquisa.

Åberg, Emil, Khati, Yeshodeep January 2018 (has links)
Title: Artificial Intelligence in Customer Interactions: A Study on Customers' Perceptionsregarding IVR Services in the Banking Industry Purpose: The purpose of this paper was to explore consumer perspectives on automated IVRcustomer services. Design/methodology/approach: This research paper was conducted qualitatively, where theresearchers developed a framework and a suggested model based on existing research andcollected primary data from eight interviews with open-ended questions. The collected datawas coded so that the researchers could spot patterns in the responses which were thendiscussed in relation to previous studies. Based on the results of the data analysis thedeveloped model was also discussed and revised. Findings: The findings of this study suggest that consumers are skeptical towards IVRtelephone customer service and believe that the service quality would be lower than regulartelephone service. The findings do however show that consumers are willing to try to adjust tonew technology as long as there are alternatives if they are not satisfied. Research implications: Managers should focus on delivering quality service to all of theirconsumers and therefore need to consider how well their services can fulfill the needs of theirconsumers. If the quality of the technology cannot provide the service that is expected there isstill a need for regular telephone customer service or else the company might suffer in thelong run. Originality/value: This study is, to the best of our knowledge, the first to explore the topic ofcustomers perceptions of AI in customer service. Keywords: IVR, AI, Customer Service, Banking, Customer Satisfaction, Wait time, TAM,Technology Acceptance Model, Sweden

Made available in DSpace on 2010-04-20T20:15:26Z (GMT). No. of bitstreams: 0 Previous issue date: 1999-04-27T00:00:00Z / Análise das comunicações externas corporativas em situações de crise, com ênfase nas relações empresa-imprensa. A crise enfocada é o acidente maior, oriundo de falhas humano tecnológicas, cujas conseqüências ultrapassam as fronteiras organizacionais e repercutem amplamente nos veículos de comunicação de massa. A abordagem privilegia possibilidades de interação com os veículos impressos de comunicação de massa que concorrem para minimizar ou agravar as dificuldades pelas quais passa a organização. O estudo se propõe discutir o conceito de crise, acidente maior, comunicações de crise e interação com a imprensa durante a crise, e relacioná-los a um modelo de empresa que reflete os ditames da comunicação corporativa, que a apresenta e a relaciona com o meio externo. A queda do Fokker 100, da TAM, em 1996, apresenta se como matéria para breve reflexão sobre a evolução de uma crise no contexto brasileiro. Desenvolvido através da análise de notícias veiculadas em diários e periódicos de expressão nacional, o caso também propicia o entendimento de como as comunicações sobre o acidente, com e através dos jornalistas, são dificultadas e agravadas por opções e posturas de divulgação de fatos que refletem um modelo de organização

Análise da intenção de adoção da computação em nuvem por profissionais da área de TI

Cogo, Gabriel Silva January 2013 (has links)
A computação em nuvem emerge quando se trata da necessidade dos desenvolvedores de TI de sempre aumentar ou incluir novas capacidades, o mais rápido possível, com o menor investimento possível. Ela vem sendo apontada como uma das maiores inovações em TI nos últimos anos e por isso vem chamando a atenção tanto da comunidade acadêmica quanto da comercial. Apesar deste crescente interesse na tecnologia pela literatura acadêmica, a maior parte do foco das pesquisas se dá nos aspectos técnicos, como potencial computacional e custos. Pesquisas sobre as preferências dos profissionais da área relativa à computação em nuvem como uma ferramenta de negócios estão limitadas a estudos de consultorias e empresas privadas. Esta pesquisa tem como objetivo apresentar um estudo do impacto de diferentes dimensões sobre a intenção de adoção da computação em nuvem por profissionais de TI. Para isto, utiliza uma variação do modelo TAM/UTAUT para verificação de intenção de adoção de novas tecnologias. O método escolhido foi a pesquisa survey, realizada a partir de um instrumento previamente proposto e adaptado, sendo feita em duas etapas: estudo de pré-teste e estudo final. Diferentes técnicas estatísticas foram empregadas para refinar o instrumento, como Análise de Confiabilidade, Análise Fatorial Exploratória e Análise Fatorial Confirmatória, utilizando o método PLS (Partial Least Squares) para Equações Estruturais. Como resultado deste refinamento emergiu um modelo teórico de pesquisa final contendo 8 dimensões e 36 itens. Como contribuição para a área de SI, o modelo teórico de pesquisa final se mostrou adequado para avaliar a intenção de adoção da computação em nuvem por profissionais de TI. A principal contribuição da pesquisa para a prática gerencial é o modelo de intenção de adoção da computação em nuvem, que pode auxiliar provedores de computação em nuvem, através da mensuração das principais razões para sua adoção, que são Utilidade Percebida e Atitude Frente à Inovação Tecnológica. Também demonstra que não existe uma relação positiva entre Segurança e Confiança e a Intenção Comportamental. Doze hipóteses foram validadas e seis das hipóteses propostas foram negadas pelos dados. Estas informações buscam fornecer material para que se possa inspirar os esforços no desenvolvimento da tecnologia como ferramenta de negócio. / Cloud computing emerges when we talk about the necessity of the IT developers to always increase or add new capabilities, as soon as possible, with the lowest investment possible. It has been appointed as one of the biggest IT innovations in the recent years, and for that reason it’s been calling the attention of the academic and management communities. Even with the growing interest by the academic community, most of the research focus on technical aspects, such as computational potencial and costs. Researches involving professionals’ preferences with cloud computing as a business tool are limited to consultant and private studies at most. This research has the purpose of presenting a study about the impact of different dimensions in the intention of adoption of cloud computing by IT professionals. To do so, it uses a variation of the TAM/UTAUT model for the verification of the intention of adopting new technologies. The research method is the survey research, made with a previously proposed and adapted instrument, conducted in two stages: pre-test study and final study. Different statistical techniques were used to refine the instrument, such as Reliability Analisis, Exploratory Factor Analysis and Confirmatory Factor Analysis, this one using the PLS (Partial Least Squares) Path modeling for SEM (Structural Equation Modeling). As a result of this refinement, emerged a theorical research model containing 8 dimensions and 36 measuring items. As contribution to the IS area, the theorical model proved adequate to assess the intention of adoption of cloud computing by IT professionals. The research’s main contribution to the business practice is the model of cloud computing intention of adoption, that aids cloud providers, trought the measurement of the main reasons behind the adoption of the technology, wich are Perceived Utility and Attitude Towards Technology Innovation. Also demonstrates that there are no positive relation between Security and Trust and the Behaviorial Intention. Twelve of the hypothesis were sustained, and six of the proposed hypothesis were denied by the data. This information intends to inspire efforts in developing the technology as a business tool.

O envolvimento do usuário como influência na adoção de sistemas de informação

Leso, Bernardo Henrique January 2018 (has links)
A presente pesquisa visa investigar o envolvimento do usuário final no desenvolvimento de um Sistema de Informação (SI) e sua influência na adoção do SI. Para tanto, realizou-se uma revisão sistemática, em que foram analisados 133 artigos e cujo resultado é a proposição de uma modificação do Modelo de Aceitação de Tecnologia (TAM) incluindo variáveis relativas ao envolvimento do usuário: situacional e intrínseco. Em seguida, foi realizado o teste do modelo proposto a partir de uma survey com 114 respondentes, cujos dados foram analisados através de Análise Fatorial Exploratória (EFA), Análise Fatorial Confirmatória (CFA) e Modelagem por Equações Estruturais (SEM). O teste permitiu inferir que as hipóteses suscitadas estavam corretas e que o envolvimento do usuário é significativo dentro do contexto de adoção de um SI. Por fim, realizou-se um projeto de experimentos fatorial (DOE) fracionado para verificar de que forma envolvimento situacional e intrínseco estão relacionados Evidenciou-se que a composição do efeito de fatores principais e de interações duplas das atividades do envolvimento situacional explica até 57% da variação do envolvimento intrínseco. As principais contribuições teóricas da dissertação versam sobre a consistência aportada pelos métodos utilizados. O subsídio teórico aportado pela revisão sistemática permitiu elaborar relações teóricas com segurança. A utilização conjunta de EFA e CFA é indicada para conferir robustez à pesquisa. Da mesma forma, a modelagem por equações estruturais apresentou utilidade no contexto da pesquisa, embora se indique cuidado ao realizar as modificações no modelo para que se adeque aos parâmetros de qualidade da análise. Por fim, a realização de um projeto de experimento fatorial fracionado é algo incomum na literatura de adoção de SI, mas foi útil para verificação da qualidade da interação entre os tipos de envolvimento, bem como a verificação de quais fatores devem ser evitados. / The present research aims to understand the end user involvement in the Information System (IS) development influence in IS adoption by proposing and testing a specific theoretical model. A systematic review was carried out in which 133 articles were analyzed and its result is a Technology Acceptance Model (TAM) modification proposition. This model includes variables related to the user's involvement: situational involvement and intrinsic involvement. Afterwards, the test of the proposed model was carried out from a survey with 114 respondents, whose data were analyzed through Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM). The test allowed inferring that the hypotheses raised were correct and that user involvement is significant within IS adoption context. Finally, a fractional factorial design of experiments (DOE) with seven factors was done to verify how two types of involvement are related. It was evidenced that the composition of the effect of situational involvement major factors and double interactions explains up to 57% of intrinsic involvement variation The main theoretical contributions of the dissertation are about the consistency provided by the methods used. The theoretical subsidy provided by the systematic review allowed development of theoretical relations with safety. The combined EFA and CFA use is strongly indicated to give robustness to the research. Likewise, SEM presented significant utility in research context, although it is indicated caution when making model modifications to fit analysis quality parameters. Finally, fractional factorial DOE with seven factors is uncommon in the literature, but it was extra useful to verify interaction quality between types of involvement.

Hur hjälper AI den svenska vården? : Sjuksköterskors uppfattning av AI inom vården

Algoz, Sara, Mussa, Amin January 2018 (has links)
Artificiell intelligens sprider sig allt mer och mer inom olika arbetsområden. I denna studie har en kvalitativ fallstudie gjorts som behandlar hur sjuksköterskors uppfattning av framtida användandet av AI inom vården kan se ut. Genom att intervjua tre sjuksköterskor, en e-hälsostrateg och en projektledare inom området analyseras även detta empiriska material med hjälp av TAM för att slutligen ta reda på hur sjuksköterskors attityder kring att använda AI i framtiden ser ut. Resultatet av studien visar att sjuksköterskors uppfattning och acceptans av AI inom vården är delad i två områden där ena är icke-beslutsfattande AI och andra, beslutsfattande AI. Resultatet visar alltså hur sjuksköterskors attityd är positiv när det kommer till icke-beslutsfattande AI och mer negativ vid beslutsfattande AI. Detta då sjuksköterskorna anser att den mänskliga kontakten försvinner vid beslutsfattande AI. Det vill säga vid användning av AI-baserade system som behåller patientkontakt och kan besluta om vilken slags vård patienten behöver. Istället menar respondenterna att maskin och människa går bäst hand i hand.
