Intensive use of ICT in school: Developing differences in students’ ICT expertise

The purpose of the study was to examine the development of students’ high-level computer skills and competence (student expertise) in information and communication technology (ICT), and to examine the characteristics of such expertise. Eighteen lower secondary school students, selected to represent both genders and all school achievement levels, were given laptops for three years to be used both at school and at home. The data of the longitudinal study consisted of a test on ICT skills; self-evaluation questionnaires on ICT competence, thoughts about their own expertise, ICT-related activities and task, interest in ICT, and classroom observations. The results of the study indicated that the intensive use of ICT and the process-oriented learning environment supported the development of student expertise. In the analysis, three groups were identified, which oriented themselves somewhat differently in relation to ICT: student experts (n = 6), advanced users (n = 8) and non-interested users (n = 4). The experts differed from the other groups in respect of especially focusing on advancing their ICT skills; they had undertaken ICT-related tasks outside the school, they had metacognitive consciousness about their competence, and they had future plans concerning ICT in their further education and profession.     

Blog-enhanced ICT courses: Examining their effects on prospective teachers’ ICT competencies and perceptions

Blogs are used as a technology support tool in teaching-learning processes in contemporary schools, especially in higher education. This paper examines the effects of using blogs on prospective teachers’ perceived ICT competencies and perceptions in blog-enhanced ICT courses. Both quantitative and qualitative research approaches were used in the data collection and analysis processes. The findings indicate that most of the participants perceived blogs to be an important tool that changed their ICT perceptions in a positive way and familiarized them with ICT. The participants also perceived the use of blogs as important for the acquisition of ICT competencies.     

利用UML映射工具实现系统可靠性建模

许多可靠性建模技术是基于可靠性框图、故障树、Markov链等表示方法，但系统架构师、产品经理和软件开发者往往对这些表示方法不太熟悉，他们通常使用统一建模语言（UML）来对系统进行描述，因此系统设计者不得不面对设计过程与可靠性建模间的缺陷。为了弥补这一缺陷，本文提出了一个利用UML映射工具实现可靠性建模的方法．同时以实际的例子演示了该方法的可行性。

Using an online tool to support school‐based ICT policy planning in primary education

An important step towards the successful integration of information and communication technology (ICT) in schools is to facilitate their capacity to develop a school‐based ICT policy resulting in an ICT policy plan. Such a plan can be defined as a school document containing strategic and operational elements concerning the integration of ICT in education. To write such a plan in an efficient way is challenging for schools. Therefore, an online tool [Planning for ICT in Schools (pICTos)] has been developed to guide schools in this process. A multiple case study research project was conducted with three Flemish primary schools to explore the process of developing a school‐based ICT policy plan and the supportive role of pICTos within this process. Data from multiple sources (i.e. interviews with school leaders and ICT coordinators, school policy documents analysis and a teacher questionnaire) were collected and analysed. The results indicate that schools shape their ICT policy based on specific school data collected and presented by the pICTos environment. School teams learned about the actual and future place of ICT in teaching and learning. Consequently, different policy decisions were made according to each school's vision on ‘good’ education and ICT integration.

ICT & learning in Chilean schools: Lessons learned

By the early nineties a Chilean network on computers and education for public schools had emerged. There were both high expectancies that technology could revolutionize education as well as divergent voices that doubted the real impact of technology on learning. This paper presents an evaluation of the Enlaces network, a national Information and Communication Technologies (ICTs) and education initiative designed as part of a series of programs to overcome inequity and quality issues of public education in Chile, by integrating teachers and learners into the knowledge society. Data gathered and the results obtained in four major areas of educational policies – infrastructure, digital literacy, conditions of learning, and the impact on school learning of major national and international tests – are presented and fully analyzed. The strengths and weaknesses of Enlaces as a visible component of the educational system and educational reform are also discussed. Enlaces has provided basic infrastructure tools, connectivity, ICTs, and teacher training to a huge number of schools, but critical results are narrow in terms of classroom learning and no additional competencies have been observed. Data and results are limited by structural bottlenecks in the educational and social system. Finally, the lessons learned after more than 15 years of implementing technology in Chilean schools are presented and fully discussed.

Lean Production—An Evaluation of the Possibilities for an Employee Supportive Lean Practice

Lean is a contested concept. It has been praised for empowering employees, and it has been criticized for intensifying work and impairing the health and well‐being of employees. This article is reviewing the literature on the relations between lean and employees, and suggests ways for the development of an employee‐supportive lean practice. There is good evidence of lean's adverse consequences for low‐skilled employees in the auto industry and other assembly type manufacturing work, but there are also examples of more positive outcomes. It is important to emphasize that, not only lean thinking, but also the context and implementation of lean have consequences for employee outcomes. Research is still needed to demonstrate it in real life, but this analysis of lean thinking, context, and implementation suggests possibilities for developing a lean practice that is genuinely employee‐supportive. © 2011 Wiley Periodicals, Inc.

ICT Capacity as the Investment and Use of ICT: Exploring its Antecedents in Africa

In this paper, we investigate the extent to which economic, human development endowment, political, and population conditions influence information and communication technology (ICT) capacity in African nations using ordinary least squares. We use five variables to measure ICT capacity: ICT expenditure as a percent of GDP (ICTE), ICT expenditure per capita in US dollars (ICTEP), investment in telecoms with private participation (INVTE), Internet users per 100 people (INTUS), and mobile phone subscribers per 1000 people (MOBPS). Unlike ICT adoption and diffusion that focuses on the use of ICT, ICT capacity measures public and private investments in ICT and the use of ICT. The results indicate that ICT capacity of a nation increases with increased (high) corruption index. Further, ICT investment by the private sector depends mainly on human development factors and is not influenced by the perceptions of corruption about a nation. We present theoretical and practical implications of the findings for developing nations in general and African nations in particular.
