EWM Conference Cambridge Sept Legacy of Apartheid in SA Education My department's policy is that Bantu education should stand with both feet in the reserves and have its roots in the spirit and being of Bantu society... There is no place for [the Bantu] in the European community above the level of certain forms of labour... What is the use of teaching the Bantu child mathematics when it cannot use it in practice? That is quite absurd. Education must train in accordance with their opportunities in life, according to the sphere in which they live. Verwoerd 1953
EWM Conference Cambridge Sept Shortage of teachers with mathematics and science qualifications a serious problem in UK and USA as well as in developing world The shortage of competent teachers results in less qualified and inadequately prepared teachers assuming teaching roles. The negative consequence hereof manifests as a vicious cycle of low quality teaching, poor learner performance, and a constant undersupply of quality teachers The South African Government National Strategy for Mathematics Science and Technology
EWM Conference Cambridge Sept The backlogs from so many years of apartheid education Illiteracy rates are high, 30% of adults over 15 years old (6-8 million adults) are not functionally literate Percentage of population over 20 years old with high school or higher qualification: 65% of whites, 40% of Indians, 17% of the coloured population and 14% of blacks Teachers in rural & township schools are poorly trained South African learners achieve poor results in international comparisons behind other African countries. In The Trends in International Mathematics and Science Study (TIMMS 2003), SA learners scored 264 points for mathematics and 244 for science compared to international averages of 467 and 474.
EWM Conference Cambridge Sept Advances in Information Communication Technology
EWM Conference Cambridge Sept Global school and university campus No age, gender, social or racial barriers How can we best use new technology to 1.promote public understanding of mathematics 2.improve the quality of mathematics education at school level – to raise standards of university intake at undergraduate level for full and part time students at research level for academic collaboration
EWM Conference Cambridge Sept Speed of penetration of ICT and expectations of change TV reached 50 million users worldwide in 38 years WWW reached 50 million in 4 years Tim Berners-Lee 1991 libwww CERN 1993 Mosaic 1994 Netscape 1995 IE WWW now has 1,173 million users, after 16 years Computers and globalisation have transformed the workplace Students today face a new era with demands for new skills Is educational change keeping pace?
EWM Conference Cambridge Sept Can ICT bridge the educational gap? The internet and communication technology is of equal importance in society to the invention of the printing press Increased public access to information and increased educational opportunities Investment in ICT infrastructure Has there been the expected widespread change in educational practice and educational standards?
EWM Conference Cambridge Sept Impact of ICT on students Students have increasing daily access to a range of technologies: cellphones, personal organisers, cameras, calculators, gps TV, videos, music, computer games internet to find information, communicate, purchase, play Most of this access is outside formal learning environment Learning is often through play Learning style inherently non-linear, experiential Reference to instruction manual is last resort Association and creativity are crucial strategies
EWM Conference Cambridge Sept Where does learning happen? Schools and universities not the only arena for education Modern society requires lifelong learning ICT contributes in other areas to the overall level of education in society eg. Health greater access for patients to information via technology improved understanding of issues by patients recording and playback of angiograms body scanning, pregnancy scanning
EWM Conference Cambridge Sept In the developed world has education failed to deliver? What is expected? What improvements in academic performance should arise from access to ICT? Technology has changed the role of people in the workplace and in society. We have easy and free access to information sources. e.g. Independent learning skills and skills in finding, analysing, understanding and communicating knowledge score over more traditional ways of learning and over learning by rote. How do we judge success in education? Are the assessment standards of the last century appropriate today?
EWM Conference Cambridge Sept Statistics on access to the internet and access to education worldwide
EWM Conference Cambridge Sept Internet Usage – The Big Picture Internet Usage – The Big Picture Updated June 2007
EWM Conference Cambridge Sept The Digital Divide Internet penetration- percentage of population Sweden 75.6% (highest in Europe) USA 69.7% Hong Kong 68.2% (highest in Asia) UK 62.3% China 12.3% South Africa 10.3% India 3.7% Sierra Leone 0.2% (lowest in Africa)
EWM Conference Cambridge Sept Access to Higher Education Average for 30 OECD countries is 47% of age group New Zealand 76% Finland 71% UK 45% USA 43% E-learning and distance learning extend access and opportunities Changes in student demography in developed world increase in proportion of age cohort in higher education student fees, student debt majority of students in employment while studying
EWM Conference Cambridge Sept Can educators use ICT to close the gaps in educational opportunities? …. not a level playing field The internet is a cheap way to distribute learning resources and provide adult education Government and local education authority networks distribute learning resources and enable sharing of ideas – including downloads and caches. Bandwidth costs favour the developed world Across Digital Divide, CDs are a cheap substitute for internet Satellite links spread connectivity to rural areas Simputer and solarpc Free Software - The Digital Divide Network –

EWM Conference Cambridge Sept Carls Question to askNRICH Carl pm 3 June: Hi, With less than 4 days to go before my A level maths exams, I really should be able to do this, and so I'm quite annoyed at myself. Please could someone help? Find, in terms of π, the complete set of values of θ in the interval: 0 θ 2 π for which the roots of equation (1) are real: x 2 +2x sin θ +3cos 2 θ = 0 (1) Now show that the roots of the equation: x 2 + (5cos2θ +1)x + 9cos 4 θ = 0 (2) are the squares of the roots of equation (1) See askedNRICHaskedNRICH
EWM Conference Cambridge Sept The response from askNRICH James pm 3 June Gives first response, advising on how to proceed Carl am 4 June Hi James, I'm going to try it myself now, I'll post a message to let you know how I got on. I think I'll be able to solve it now. 9 more messages with discussion of the concepts and method Carl pm 5 June That makes it very clear, thanks very much. It must have taken you a while. If you're doing uni exams, good luck to you too! …. See Onward & Upward on askNRICHOnward & Upward on askNRICH
EWM Conference Cambridge Sept Please Explain By Woon Khang Tang, age 17, to askNRICH Thank you!!! Even though I don't really understand at first glance, but I'll print it out and read it again until I understand. I'm sure I'll understand, and a million thanks for your detail explanation. I'm really desperate after I've gone through dozens of books and my teacher didn't explain why. I was really surprised when I asked my friends and they told me just memorize the formula. As long as you know how to apply the formula, it's ok. I really hate to memorize formulas without understanding and proving them. Without understanding the formula, when I apply the formula, it's like you can find the right answer easily, but you don't know what the heck are you doing, and that's really really stupid!!!

EWM Conference Cambridge Sept Global-campus e-learning for school students NRICH has helped spread the idea that maths can be something the world can do together. It has increased awareness that there is maths going on everywhere. We have fun doing these problems. (Secondary teacher, NRICH Evaluation 1997/98)
EWM Conference Cambridge Sept Problem Solving A Gateway to Research Moving forward from teaching and learning about mathematics to include more teaching and learning how to do mathematics how to communicate mathematics

EWM Conference Cambridge Sept AIMSSEC needs funds to continue its work in South Africa and every little helps: £2.50 pays for a learner in SA to take part in a video-conference masterclass linking SA & UK schools. This pays for the bus to take the learners to the Science Centre in Cape Town and for all the expenses connected with the video-link. Usually 120 South African children take part in each video-conference. £10 pays for a resource pack of learning materials for teaching mathematics. £300 pays all expenses for a teacher for a 10 day residential professional development course followed by 3 months distance learning. This includes travel, tuition, accommodation, food, stationery and a package of teaching and learning materials to take back to school. £15,000 is the total cost of a 10-day residential course for 50 teachers followed by 3 months distance learning. The AIMSSEC account is administered by the University of Stellenbosch. For details of how to make a donation through the Stellenbosch Foundation Charitable Trust see: Please send a covering letter saying that the donation is to AIMSSEC and what you would like the money to be used for.
