Selamat Datang欢迎VaazhgaWelcome

Professor David WrayUniversity of Warwick,United KingdomDr Dahlia JananUniversiti Pendidikan Sultan Idris, MalaysiaSlide2

Many thanks for coming to today’s meetingFunded by the British Academy and Universiti Pendidikan Sultan Idris

A project to establish a research network to explore the concept and operation of readability in a range of languages and scriptsSlide3

What we would like from the dayTo share some ideas and to make you as enthusiastic as we are about this topicTo develop some plans for building a research networkTo develop a clearer view about what nextSlide4

The Contested Concept ofSlide5

Exploring the nature of readabilityThe science (or is it art) of matching texts to readersA taken-for-granted concept – even Word does it for you!

Easily measured, easily understood http://www.online-utility.org/english/readability_test_and_improve.jsp It’s just about how difficult texts are to readIsn’t it …..?Slide6

How difficult is this text?Slide7

Is this text easier or harder?Slide8

Word says:

Reading Ease = 65.9Reading Grade level = 6.8Slide9

Word says:

Reading Ease = 65.4Reading Grade level = 6.9Slide10

Word’s readability scores for these two texts are almost identical. Yet they are clearly different in nature and effect on the reader.Slide11

Exploring the nature of readabilityIn research into readability, measuring it has tended to get more attention than actually analysing what it is.Measurement has usually been approached through the use of formulae.For example, Flesch Reading

Ease score = 206.835 − (1.015 × ASL) − (84.6 × ASW) Where: ASL = average sentence length (number of words divided by number of sentences); ASW = average word length in syllables (number of syllables divided by number of words) Slide12

Exploring readability formulaeWe applied 6 commonly used readability formulae to 64 texts chosen by primary school children.The first table shows correlations between the rank ordering of the texts by the six formulae.The second table shows the mean grade levels assigned to the texts by the six formulae.Slide13

Exploring readability formulaeThese results suggest that the readability formulae (with the exception of the Dale-Chall) generally agree about which texts are harder and which are easier.But they do not agree about the levels of difficulty of the texts.Therefore a teacher cannot rely on them to match texts to readers.Slide16

Why such variability?Various formulae measure different thingsWord lengthSentence length

Unfamiliar / Difficult wordsPolysyllabic wordsEach of these is problematicSlide17

Legibility can

be quite hard to deal withSlide23

Readability has faded from view – or has it?Slide24

Readability has faded from view – or has it?Research into readability has seriously declined in educational fields.But the concept is still heavily used in Health and Medical fields.Slide25

Readability has also become theoretically problematic

The procedure is actually quite simple. First you arrange things into different groups. Of course one pile may be sufficient depending on how much there is to do. If you have to go somewhere else due to lack of facilities that is the next step, otherwise you are pretty well set. It is important not to overdo things. That is, it is better to do too few things at once than too many. In the short run this may not seem important but complications can easily arise. A mistake can be expensive as well. At first the whole procedure will seem complicated. Soon however, it will become just another facet of life. It is difficult to foresee any end to the necessity for this task in the immediate future, but then one can never tell. After the procedure is completed one arranges the materials into different groups again. Then they can be put into their appropriate places. Eventually they will be used once more and the whole cycle will then have to be repeated. However, that is a part of life.Most 9 year olds could ‘read’ this aloud, but not understand it.Slide26

Changing paradigmsTheories of readability have changed because theories of reading have changed. Think how much information the reader supplies in the following short texts.

Mary heard the ice-cream van coming down the street. She remembered her birthday money and rushed into the house.Mary heard the bus coming down the street. She remembered her birthday money and rushed into the house.Slide28
