I have read Tania’s comments on the article. It triggers me to reflect on myself. I found out that I am pretty much similar to the third teacher Pamela with 30 years experience who had reserved attitude to tbe use of technology although she was open to use technology in her pedagogical practice. What I learnt from this article are:

-  The technology-enriched pedagogy shold be promoted in secondary classroom. Use technologies that are relevant and available such as CAS calculators, computing software to help students understand mathematical concepts rather than use them as computational tools.

-  The role of a mathematical teacher should be transformed from a teacher-centred practitioner to a learner-centred practitionner. Use of technologies could facilitate student-centred learing environment and encouge students to graphically explore and better understand mathematical ideas and principles. It depends on to what extent we understand and employ constructivst approaches to teaching and learning.

- As a pre-service teacher, I am aware of that the prefessional community  of mathematics teachers will have an impact on a teacher’s attitude to use technologies, and vice versa. I need to update the knowledge of technologies and prepare for the technology-enriched pedagogical practice.
