In November 1998, the Hong Kong Government published the policy document entitled "Information Technology for Learning in a New Era Five-Year Strategy 1998/99 to 2002/03" and defined the goals and the scope of the development of Information Technology in education in Hong Kong. One of the goals is to encourage using Information Technology (I.T.) in education and to promote students' ability in handling information. As the role of I.T. is becoming more and more important in education, schools themselves have also implemented I.T. to various extents. The main purpose of this study is to explore the impacts of the external environment on the development of I.T. in Hong Kong primary schools and examine also the relationship between the use of I.T. in education and teaching effectiveness in Hong Kong primary schools.
This study uses a quantitative approach to achieve the above purposes. Questionnaires were sent to 823 teachers from 25 Hong Kong primary schools to solicit their views on the impact of I.T. in school education, the use of I.T. education and their perceptions of teaching effectiveness.
The School Environment Constraint Instrument developed by Lam (1989) was adopted to meet the context of Hong Kong primary schools and modified for this study. Two new factors "New Arrivals" and "Language Policy" are used to replace the original factors of 'Ethnicity' and 'Second Language'. The other two research instruments which measured "Information Technology Development" and "Teaching Effectiveness" were developed by the Researcher.
The results of the research indicate that: (1) the "Policy" factor and "Funding" factor had a high, significant correlation with the different aspects of I.T. development of Hong Kong primary schools; (2) a school with well-developed I.T. had a positive significant correlation with "Teaching Effectiveness".
Recommendations have been made for school administrators' consideration in the development of I.T. systems in primary

This study attempts to understand how students construct their knowledge in a new learning environment guided by constructivist learning principles as well as to find out whether such environment can produce a deeper learning outcome than one that is based on existing mode of classroom teaching.
A constructivist learning environment includes such crucial elements as intentional learning, active, authentic and cooperative learning. This involves using information technology to build up learning community as well as encourage learners to obtain information for knowledge construction.
A quasi-experimental design was employed. The experimental group comprised of 16 students taking a Social Policy Issues course via an online learning environment while the comparison group comprised of 18 students attending the same course in the existing classroom teaching. All students came from the same class studying in the final year of the BSW program of the University of Hong Kong. Background information indicated that the two groi.lps of students were largely, homogeneous.
The outcome indicates that students had a positive evaluation of the online learning environment. However, the learning outcome analyzed by the SOLO Taxonomy does not show any significant difference. The students with better performance are more active in logging on the online course and post more messages on the bulletin board.
Patterns of students' participation in the bulletin board discussion were analyzed Students were enthusiastic in the beginning and the more active students tended to remain so throughout the course. Quality of postings improved with time on each discussion topic. Quite a few students reported that they preferred reading others' postings than giving their opinions. Teachers' roles were investigated. Giving encouragement, asking short and thought provoking questions and summarizing students' discussion were considered important for students' learning.
The study suggests
