Increased impact of technology leads numerous studies to conduct research on the effect of social media on performance. Very limited of such studies have tried to observe and record the use of social media for collaborative learning as a way to improve collaborative authoring. This paper tries to the validation of the technology acceptance model (TAM) on social media use for collaborative learning to enhance collaborative authoring among research students. To achieve the study objective, this paper employed a questionnaire as the main data collection method and distributed it to 1118 responses of various researchers from the Universiti Teknologi Malaysia (UTM) all of whom use social media. The findings were obtained via a quantitative research method, structural equation modeling (SEM-AMOS). The findings from our empirical study indicate that all the hypotheses were supported; we demonstrate that the use of social media positively and significantly related to collaborative authoring through collaborative learning between researchers in higher education. Therefore, the proposed model will help academic and decision-makers formulate the strategies that can encourage students and researchers to use social media to improving collaborative authoring through collaborative learning.

近年來互動數位敘事(Interactive Digital Storytelling, IDS)的發展日漸被重視，有部分研究針對互動數位敘事開發故事腳本編輯工具，雖然這些編輯工具考慮了沒有互動數位敘事腳本編劇經驗的作者，但仍缺乏創作豐富度、工具易用性及共同創作功能。本研究目標為建立互動數位敘事之智慧型共同創作平台( Intelligent Collaborative Authoring Platform, iCAP )，透過將故事元素視覺化，故事內容設定參數化等，加上智慧型檢驗運算，讓故事編劇們能夠透過此平台編修互動故事腳本，並在舞台環境中呈現新的故事內容。我們以現有的互動數位敘事系統The Theater[1]為舞台呈現，透過iCAP整合其故事腳本及環境建置設定。我們建立了簡單易懂的操作介面、規劃故事腳本可修改範圍的限制、將故事動畫腳本設定參數化、建立的故事腳本的共同創作機制以及輔助創作的智慧型提示與結果運算，並設計一系列的任務式實驗以及評估問卷來評估系統，透過實驗結果驗證了本研究的智慧型共同創作平台的價值，能讓不同的腳本編劇在此平台上方便、快速的工作，而使得互動數位敘事之腳本編輯變得較簡易，修正演出效果時將更加有效率，故事內容也更豐富。 / Interactive Digital Storytelling (IDS) has become more popular these days. Some of the pre-vious researches about IDS have considered the design of story editor. Although they have designed the authoring tools for authors who may not have the editing experience of IDS sto-ries, they usually lack the features of enabling rich contents, easy-to-use, and collaboration among multiple users for IDS story editing. Our system, named iCAP, is an Intelligent Col-laborative Authoring Platform for IDS, using "The Theater" as the IDS animation platform. The iCAP system contains a graphical user interface for making the story editing process eas-ier and the storyline more readable. The iCAP system includes the collaborative features such as the settings of access rights, the parameterization of the scenario settings, the authoring logs of the collaborative process, and the intelligent error detecting tool that is used to detect the errors occurring in a story structure. We have conducted an experiment to verify the usa-bility and the collaborative features of iCAP. In addition, we have obtained feedbacks from the users about the advantages and disadvantages of iCAP and verified the value of the plat-form for IDS.

In spite of the popularity of technologies that facilitate distance learning, institutions still educate students who gather together in shared physical spaces. But now even these traditional settings for learning are more collaborative and technology-rich environments. Qualitative methods in the sociolinguistic tradition allowed me to attend carefully to the vocal and non-vocal interactions of students engaged in a computer supported collaborative authoring assignment. Three research questions guided my inquiry: 1) In what ways did students negotiate roles and responsibilities?; 2) In what ways did students negotiate access to their assignment?; and 3) what was the nature of discourse in computer supported collaborative authoring? I conducted microanalysis of the communication in online discussions and face-to-face discourse throughout an entire semester of one graduate level course entitled The Psychology of Teachers and Teaching. My data revealed that the online discussion forum, physical proximity to the computer during face-to-face collaboration and instructor influence shaped the students’ roles and responsibilities as well as their entry into the assignment. I propose a model illustrating how students negotiate entry into computer supported collaborative authoring assignments and discuss its implications for teaching and learning. / text

O objetivo principal desta dissertação explora alguns aspectos relacionados ao desenvolvimento colaborativo de sistemas de informação na Internet. E apresentado o Editor Diagramático na Internet (EDI), que suporta a especificação colaborativa de aplicações. Este editor utiliza tecnologia e funcionalidade dos hiperdocumentos, oferecendo características como: compartilhamento de informações, colaboração entre vários autores e varias visões dos dados conceituais armazenados. EDI foi implementado utilizando a linguagem de programação Java e projetada de forma genérica para permitir a criação de editores de diferentes notações diagramáticas. Este trabalho propõe a utilização de anotações em documentos de desenvolvimento de sistemas de informação na Internet. Estas anotações auxiliam no desenvolvimento colaborativo de sistemas, tornando o processo mais colaborativo e com um produto resultante de qualidade superior. As anotações estão baseadas em dois tipos de usuários: o usuário proprietário, responsável pela criação do documento, e o usuário colaborador, que inclui anotações nos documentos. Anotações (identificadas por uma especifica cor) podem ser de inclusão, alteração, remoção de conceitos (visões) ou registro de comentários. / The main goal of this work is to explore some issues related to collaborative development of information systems on the Internet. A Diagrammatic Editor on the Internet (EDI) that supports collaborative specification of applications is described. This editor uses hyperdocument technology and funcionalities, offering features such as information sharing, collaboration between several authors, multiple views of the stored conceptual data, among others. EDI was implemented using the Java language, and designed with the purpose of being generic to enable the easy creation of specific editors for different diagrammatic notations. The use of annotations for the joint development of information systems on the Internet is proposed. With these annotations the development process becomes more collaborative and the quality of the final product may increase. Annotations are based on two types of users: the owner, who is an author responsible for the creation of a document, and the collaborator, who makes annotations on those documents. Annotations (identified by one specific colour) can be of inclusion, change and removal of concepts (views), or recording of comments.
