00:00:00.010 --> 00:00:02.669
We know mathematics textbooks and

2
00:00:02.669 --> 00:00:06.629
classroom pedagogy are crucial in students'

3
00:00:06.629 --> 00:00:10.110
learning of mathematics. However, to

4
00:00:10.110 --> 00:00:12.179
support high-quality mathematics

5
00:00:12.179 --> 00:00:15.360
textbooks and to promote effective

6
00:00:15.360 --> 00:00:19.410
classroom pedagogy of teachers, we also

7
00:00:19.410 --> 00:00:23.760
must support teachers, since teachers

8
00:00:23.760 --> 00:00:27.480
play a most important role in improving

9
00:00:27.480 --> 00:00:31.230
the quality of teaching and students'

10
00:00:31.230 --> 00:00:35.399
learning. Traditionally, people often view

11
00:00:35.399 --> 00:00:41.300
having obtained pre-service training

12
00:00:41.300 --> 00:00:45.410
and gained a teaching qualification,

13
00:00:45.410 --> 00:00:49.379
is enough for being a teacher. Nowadays,

14
00:00:49.379 --> 00:00:52.739
there are more and more people who think

15
00:00:52.739 --> 00:00:56.579
this is not so. Accordingly, teachers'

16
00:00:56.579 --> 00:01:00.230
in-service training and/or continued

17
00:01:00.230 --> 00:01:04.379
professional development, we call CPD,

18
00:01:04.379 --> 00:01:08.010
have also received increasing attention

19
00:01:08.010 --> 00:01:12.299
in many countries, including many Asian

20
00:01:12.299 --> 00:01:16.290
countries such as Singapore, China, Japan,

21
00:01:16.290 --> 00:01:20.909
and Korea. Below we should introduce

22
00:01:20.909 --> 00:01:25.110
the CPD practices in Singapore and in

23
00:01:25.110 --> 00:01:30.000
China or Shanghai.
