Computers are increasingly widespread, influencing many aspects of our social and work lives, As we move into a technology-based society, it is important that classroom experiences with computers are made available for all students. The purpose of this study is to examine preservice teachers’ attitudes towards computers. This study extends the technology(More)
Preparing preservice teachers for ICT integration in the classrooms is a key focus for many teacher education institutes. This paper examines the perceived development of preservice teachers in terms of their technological knowledge, pedagogical knowledge, content knowledge and the synthesis of such knowledge, i.e., the technological, pedagogical, and(More)
Within the field of educational technology, Technological Pedagogical Content Knowledge (TPACK) has been theorized as a seven-factor construct to describe teacher’s integration of information and communication technology (ICT) in their teaching. However, this framework has yet to be successfully validated through survey instruments. This paper examines the(More)
As computers becomes more ubiquitous in our everyday lives, educational settings are being transformed where educators and students are expected to teach and learn, using computers (Lee, 2003). This study, therefore, explored pre-service teachers’ self reported future intentions to use computers in Singapore and Malaysia. A survey methodology was employed(More)
Teachers’ epistemological and pedagogical beliefs and their attitude about ICT are identified as the second-order barrier for the integration of ICT into classrooms. In this paper, we report the findings obtained from our recent survey and conducted among Singaporean and Taiwanese pre-service teachers (N=108). The results indicate that the teachers’(More)

Sol-gel technology offers an alternative technique for producing bioactive surfaces for improved bone attachment. Previous work indicated that monophasic hydroxyapatite coatings were difficult to produce. In the present work hydroxyapatite was synthesized using the sol-gel technique with alkoxide precursors and the solution was allowed to age up to seven(More)
Production of hydroxyapatite coatings using an alkoxide-based sol-gel route requires control of solution aging time and heating schedule. 31P nuclear magnetic resonance spectroscopy was used to investigate the changes during aging of the sol and thermal gravimetric analysis employed to study the behavior of the xerogels as a function of temperature, while(More)
