Relay Thinking (RT) is a thinking process borrows the concepts found in running a relay race. These concepts are then modify so that the co-operative advantages found in a "relay" are put in group thinking projects. In 1997, eight secondary Design and Technology (D&T) students used RT to generate ideas in order to solve a pre-set problem. The objective of this study was to see the possibilities and limitations of using the process in D&T problem solving activities. The performance of the students were noted during the thinking activities and interviews were conducted after the activities. The interviews did not aim at investigating the students' solutions to the problem, but rather their experience in using RT.
In this paper the concept of RT will first be described. The results of the study of the secondary students using the process will then be presented. From the results of the study, RT provides an alternative to individual and group thinking experiences, although some modifications on the thinking activities are necessary. The results also indicate that secondary students should be provided with more opportunities to have group co-operation in problem solving activities.

Millions of people now have access to the Internet, and the number is increasing every day. The World Wide Web (WWJI9 is the most visible, graphical and fast-growing part of the Internet. The role of education in this domain has been studied in recent years.
Some have tried to improve the instruction process through appropriate integration of technology via the WWW Does the access to the WWW which can be regarded as an Information Superhighway, deliver the anticipated renewal of teaching and learning? If so, under what conditions? Or to what degree? In this paper, we will focus our attention on the teaching and learning in mathematics and provide a preliminary exploration of the above questions.
A self-learning package in elementary number theory with the WWW has been developed for the pre-service teachers in our Full-time Certificate of Education (Primary) Course at HKIEd. In this paper, we will also explain our rationale in choosing the topics and the difficulties in our design and implementation.
