Important Field

The study of conceptual models is both a complex and an important field within the HCI domain. Many of its key principles resulted from research and thinking carried out in the 1980s, arguably in the wake of Norman (1983). Since then, the importance of conceptual models in affecting the usability of an Information and Communication Technology (ICT) system has become well-established (e.g., they feature prominently in the widely cited design guidelines for interfaces defined by Norman [1988], which are summarized in Figure 1 by Lienard [2000]). Today, most HCI professionals are able to attribute significant meaning to the term conceptual model and to recognize its importance in aiding usability. However, two problems seem to prevail. First, some HCI researchers and practitioners lack a precise understanding of conceptual models (and related ideas), and how they affect usability. Second, much of the research in this field is (necessarily) abstract in nature. In other words, the study of conceptual models is itself highly conceptual, with the result that practitioners may find some of the theory difficult to apply. This article is designed to help both researchers and practitioners to better understand the nature of conceptual models and their role in affecting usability. This includes explaining and critiquing both contemporary and (possible) future approaches to leveraging conceptual models in the pursuit of improved usability.

This paper analyzes the reciprocal influences between various teaching methodologies supported by information and communication technology (ICT) and the teaching objectives that are pursued by means of these methodologies. The authors present the main characteristics of the conceptual model which has led to the definition of the teaching objectives and the results of the experience of the “eLearning@LIUC” project, where the validity of the hypotheses underlying the model has been tested through their application within concrete contexts. They believe that the presented model, with its analysis of the possible correlations between teaching objectives, teaching methodologies and technological tools, can provide a new awareness of the opportunities offered by the adoption of ICT in teaching.

Customized Learning

Instructors face difficulty in creating student-centred, customized learning designs (LDs) for teaching with information and communication technology (ICT) tools such as visualizations (animations, simulations or videos). This problem is compounded for tertiary-level instructors teaching in instructor-mediated classrooms. In such classrooms, common in many parts of the developing world, students may not have 1:1 access with the visualization and have to interact with it via the instructor. Here, the instructors’ pedagogy becomes an important factor determining effective learning with the visualization. To address this problem, a set of design impediments faced by instructors in this context were first identified. Design guidelines were created to address these impediments. These guidelines evolved into the Customized Visualization Integration System (CuVIS). It is a wizard-like interactive tool that provides guidelines to instructors on how to create effective LDs that incorporate the principles of constructive alignment and meaningful learning with ICT, and is customized to instructors’ requirements. The effectiveness of CuVIS has been tested with instructors along multiple dimensions: usefulness and usability, impact on instructors’ pedagogical practice and impact on student learning when taught with CuVIS-generated LDs.

Depth Interviews

This study aims to identify factors to be considered when developing Information and Communication Technology (ICT)-integrated classroom models and to suggest a conceptual framework for considering more appropriate classroom models, tailored to the environments and needs of each developing country. In-depth interviews were conducted with experts, yielding many factors to be taken into account when integrating ICT in various educational contexts of developing countries. The factors are categorized into five domains: current status and relevant policies in ICT education, ODA (Official Development Assistance) goals and priority setting, infrastructure and technical challenges, pedagogical methods, and educational resources. Based on the recommendations elicited for the five categories, we suggest a conceptual framework that provides practical guidance on the criteria for selecting classroom models suited to each partner country’s environments and contexts. This study also draws implications from the interviews for classroom design guidelines related to hardware and infrastructure, to improve the sustainability of ICT-integrated classroom projects.

The article aims to evaluate the existence of a coevolution between internationalization strategies and innovative performance within information and communication technology (ICT) companies located in the northeast of Brazil. In order to achieve this objective, a conceptual model was derived from the literature review contemplating the vision that internationalization and innovation within companies happen in an evolutionary and dynamic way. Methodologically, the study is characterized by being qualitative, using the technique of multiple cases. The studied companies (IVIA, IFACTORY, CPQI and GREENMILE) presented changes in both internal and external competences. Thus, a main conclusion has been that the studied companies presented a process of coevolution between innovation and internationalization strategies. In terms of business strategies, it can be verified that the presence of these two processes, guarantees the development and growth of companies in the global market.

motorcycle taxi drivers are a group of laborers in the informal sector who are socially shunned and are often harassed by the authorities and local influential people. Research has found that motorcycle taxi drivers have the potential to gather information concerning problems occurring in public spaces to be compiled into a database to encourage problem solving. Furthermore, smartphones are found to be a tool that assists motorcycle taxi drivers in effectively collecting information relating to problems that they encounter. Thus, the researcher, in collaboration with motorcycle taxi driver groups, has developed key concepts andan Information and Communication Technology (ICT) system that can contribute to the motorcycle taxi drivers’ becoming community reporters. Guidelines are also proposed for using the ICT system for reporting community problems to build a creative relationship between motorcycle taxi drivers and governmentinstitutions in managing public space.

Abstract In a paper an application of the architecture evaluation method used for prediction the effects of incidents for information security which is inside of Information and Communication Technology (ICT) system is described. As a base, the ATAM method is taken. During the analysis there is shown, that direct use of the ATAM technique is impossible, because it use only one set of data. Use just one view of ICT system is not adequate for measure the influence of incident on information security, which is inside ICT system. A tool which is useful for assessment effects of incidents, is an incidence matrix that presents logical connections between elements of ICT system. Knowledge of logical connections and structures of the messages being exchanged enables an assessment of operation the elements which receive modified messages.

This paper studies whether and how information and communication technology (ICT) changes self-construal and cultural values in a developing country. Ethiopian children were given laptops in the context of an ICT for development scheme. We compared children who used laptops (n = 69) with a control group without laptops (n = 76) and a second control group of children whose laptop had broken down (n = 24). Results confirmed that after 1 year of laptop usage, the children’s self-concept had become more independent and children endorsed individualist values more strongly. Interestingly, the impact of laptop usage on cultural values was mediated by self-construal (moderated mediation). Importantly, modernization did not “crowd out” traditional culture: ICT usage was not associated with a reduction in traditional expressions (interdependent self-construal, collectivist values). Theoretical and practical implications are discussed.
