Factors that influence pre-service teachers’ ICT usage in education

The purpose of the current study was to investigate the role of internal factors (e.g. attitudes towards computers and internet, self-confidence, and knowledge) and external factors (perceived support) on the level of information and communication technology (ICT) usage. The participants were 1898 pre-service teachers in Turkey. The results revealed that Turkey, like many other developing countries in the world, is in the early phase of ICT integration in education. Most pre-service teachers reported that they use only basic ICT applications for educational purposes. Internal and external factors were found to be related to each other and to ICT usage level. In general, male pre-service teachers’ knowledge and usage levels of ICT were higher than that of female teachers.     

高等教育自学考试复本试卷的设计及其平行性控制

复本试卷的平行,是确保自学考试标准稳定的重要手段。影响试卷平行的因素包括试卷结构、知识内容、难度分布、认知层次的构成等,它们从不同维度上共同构成了平行试卷的指标控制体系。在命题和题库建设中,通常使用命题细目表和知识内容赋分比例表作为控制试卷平行的手段。     

Factors (not) affecting what students do with computers and internet at home

This paper presents the results of an analysis of secondary students’ computer use, aimed at understanding how different factors influence the profile of activities carried out by students with computers. The analysis is based on the data from a national study aimed at measuring students’ Information and Communication Technology (ICT) skills for learning. A factor analysis was carried out to categorize students’ activities with computers and several indexes were constructed to define the comparison groups. Finally, a multiple linear regression analysis was performed to explain the frequency of the activities. Results show that students with access to computers at home mainly perform activities categorized as Socializing, Academic, Gaming and Production and that although the absolute frequency of these activities differs across groups, the profiles of computer use are surprisingly similar for groups based on students’ socio-economic group, experience with ICT, and self-confidence in the use of ICT. The only variable that discriminates user profiles is gender. Based on these findings, it can be claimed that Chilean secondary students with access to computers at home tend to show a rather homogenous computer-use profile, once access is equated.

A high-dexterity low-degree-of-freedom hybrid manipulator structure for robotic lion dance

Lion dance is a very popular and lively Chinese traditional art form. A robotic project in Singapore has been dedicated to the design and demonstration for similar traditional art forms using modern mechatronics technology. This paper deals with a novel six-degree-of-freedom （6-DOF） hybrid manipulator with high stiffness, high loading capability and high dexterity, mimicking the lion dancer＇s upper body motions along with the lion head movements. The design of the hybrid manipulator consists of a 2-DOF torso structure in serial configuration and a 4-DOF dual arm structure in parallel configuration. The combined 6-DOF hybrid manipulator can support the weight and dynamics of the lion head during the lion dance performance. Forward kinematics of the manipulator has been formulated and visualized for design purposes. Inverse kinematics of the hybrid manipulator were analytically derived for real-time motion control. Based on the design and modeling, a complete hybrid manipulator has been fabricated, implemented into the robotic lion, and successfully demonstrated for real robotic lion dance performance.

A Retrospective: Fifteen Years of Computers in English

The initial observations of English teachers that computers have the potential to support collaboration, creativity, independent learning, subversion and reflection have been confirmed by fifteen years of work in the field, as have early concerns that computers could be used to direct inappropriate activities. Questions about the role of the teacher, the function of the computer, as well as the nature of pupils' learning when using IT, are now much better understood. Yet changes in the educational context within which English teachers are working, new understandings engendered by major curriculum projects and developments in the technologies themselves have brought about a shift in understanding of the significance of IT and its impact on the English curriculum. This paper shows how publications from the NATEMCET stable reflect the emergence of the field of English and IT.
