Reducing the "Information Gap" Between Synchronous and Asynchronous Co-operative Design Phases

This paper aims to describe a particular role of annotations as co-operative artefacts in engineering design. In co-operative processes, where achieving a shared understanding between the participants from different domains is crucial, sharing the decisions and argumentations which lead to a solution is as important as sharing the solution itself. In our case study, we describe what we call an "information gap" between the asynchronous phase, when individual decisions are made, and the design review, when the solution is evaluated, and collective thinking influences the decisions. Then, within a conceptual design scenario, we show how semantic annotations can create a shared environment to help to reduce this gap, where all actors are able to elicit domain-specific constraints and engage discussions on design solution during the asynchronous phase.semantic annotation; engineering design; design communication; collaborative tool

Instructor versus Peer Attention Guidance in Online Learning Conversations

This paper reports a theory-driven experimental study for designing and evaluating two different forms of attention-guidance functionalities integrated into an anchored-discussion system. Using social constructivism as a motivating theory, we constructed a theoretical framework that emphasizes the importance of students’ attention allocation in online learning conversations and its influence on message quality and interaction patterns. The development of the functionalities, named faded instructor-led and peer-oriented attention guidance, aimed to direct students’ attention toward instructional materials’ central domain principles while offering them an open learning environment in which they could choose their own topics and express their own ideas. We evaluated the functionalities with heat map analysis, repeated measures general linear model analysis, and sequence analysis to assess the utility of the developed functionalities. Results show that attention guidance helped students more properly allocate their attention in online learning conversations. Furthermore, we found that the improved attention allocation led to better quality of students’ online learning conversations. We discuss implications for researchers and practitioners who wish to promote more fruitful online discussions

PlanetOnto: from news publishing to integrated knowledge management support

Given a scenario in which members of an academic community collaboratively construct and share an archive of news items, several knowledge management challenges arise. The authors' integrated suite of tools, called PlanetOnto, supports a speedy but high quality publishing process, allows ontology-driven document formalization and augments standard browsing and search facilities with deductive knowledge retrieva

The Affordances of Social Annotation in the Online Writing Classroom: A Community of Inquiry Analysis

Social annotation (SA) is a genre of web-based applications that allow users to annotate texts and to see and respond to annotations others have written. To explore the potential of SA for teaching writing online, findings from twelve empirical studies of SA in education were analyzed through the lens of the Community of Inquiry framework. Results indicate that SA can contribute to cognitive presence, social presence, and teaching presence in online writing instruction. SA supports collaborative understanding and unpacking of texts. Students can identify and discuss main ideas, claims, rhetorical moves, evidence, etc. They can ask and answer questions. The demands of articulating their views and comparing them to those of others cause students to become aware of their thought processes, a metacognitive development. Pedagogical strategies such as highlighting important concepts and seeding expert annotations can focus attention and scaffold learning. SA can promote the development of community as students collaborate and encourage one another. Teachers can plan and monitor SA activities aligned with learning outcomes. The findings provide insights to guide incorporation of SA in online writing instruction

Building a semantically annotated corpus of clinical texts

In this paper, we describe the construction of a semantically annotated corpus of clinical texts for use in the development and evaluation of systems for automatically extracting clinically significant information from the textual component of patient records. The paper details the sampling of textual material from a collection of 20,000 cancer patient records, the development of a semantic annotation scheme, the annotation methodology, the distribution of annotations in the final corpus, and the use of the corpus for development of an adaptive information extraction system. The resulting corpus is the most richly semantically annotated resource for clinical text processing built to date, whose value has been demonstrated through its use in developing an effective information extraction system. The detailed presentation of our corpus construction and annotation methodology will be of value to others seeking to build high-quality semantically annotated corpora in biomedical domains

Using a video annotation tool for authentic learning: A case study

In e-learning there is increasing need for active learning designs that highlight reflection. Video sharing is one such option. The Media Annotated Tool (MAT), developed at RMIT University, provides the opportunity for students to annotate their own and other students' videos of learning tasks. Teachers provide feedback, coaching and scaffolding using this tool to develop professional skills. This approach provides an authentic learning opportunity, where students engage in 'real world' experiences. This paper uses the results of a pilot study on MAT conducted in 2009 and links the design and learning experiences of students to the nine characteristics of authentic learning as outlined by Herrington et al., (2010)

Case Study of Using a Social Annotation Tool to Support Collaboratively Learning

The purpose of the study was to understand student interaction and learning supported by a collaboratively social annotation tool — Diigo. The researcher examined through a case study how students participated and interacted when learning an online text with the social annotation tool — Diigo, and how they perceived their experience. The findings suggested that students participated actively in the collaborative learning activity and were engaged in a variety of behaviors including self-reflection, elaboration, internalization, and showing support. Although students generally had a moderately positive attitude toward using the social annotation tool for collaborative learning, a few problems were identified. In particular, students found it distracting to navigate through a large amount of annotation while reading the text. The study has implications for future research on using or developing social annotation tools for educational purposes

Building information modelling (BIM) implementation and remote construction projects: issues, challenges, and critiques.

The construction industry has been facing a paradigm shift to (i) increase productivity, efficiency, infrastructure value; quality and sustainability (ii) reduce lifecycle costs, lead times and duplications via effective collaboration and communication of stakeholders in construction projects. This paradigm shift is becoming more critical with remote construction projects, which reveals unique and even more complicated challenging problems in relation to communication and management due to the remoteness of the construction sites. On the other hand, Building Informational Modelling (BIM) is offered by some as the panacea to addressing the interdisciplinary inefficiencies in construction projects. Although in many cases the adoption of BIM has numerous potential benefits, it also raises interesting challenges with regards to how BIM integrates the business processes of individual practices. This paper aims to show how BIM adoption for an architectural company helps to mitigate the management and communication problems in remote construction project. The paper adopts a case study methodology, which is a UK Knowledge Transfer Partnership (KTP) project of BIM adoption between the University of Salford, UK and John McCall Architects (JMA), in which the BIM use between the architectural company and the main contractor for a remote construction project is elaborated and justified. Research showed that the key management and communication problems such as poor quality of construction works, unavailability of materials, and ineffective planning and scheduling can largely be mitigated by adopting BIM at the design stage

UNDERSTANDING THE PARADOX OF MENTAL EFFORT IN ONLINE LEARNING CONVERSATIONS

This study investigates inquiry-based interaction and learning outcomes mediated by two types of artifact-centered discourse environments. The study aims to promote social construction of knowledge by optimizing the division of mental effort between pragmatic and semantic grounding activities. We present a theoretical research model by combining social constructivism, grounding theory, and cognitive load theory. We carried out a quasi-experimental study using survey instruments, content analysis, sequential analysis, and knowledge tests for a holistic approach to understand the paradox of mental effort in online learning conversations. The primary finding of this study is that a linked artifact-centered discourse environment facilitates pragmatic grounding activities to attain a common ground in online learning conversations. Additionally, less need for pragmatic grounding activities leaves more room for semantic grounding activities. Finally, more semantic grounding activities lead to a deeper understanding of the learning material
