Marie Clay's oral language book, Biks and Gutches is an easy-to-administer- and-score task. It looks too simple to be very useful but with it we can easily predict which young children need extra help with learning English. Giving this assessment to individual children will help the teacher to become a better judge of how a childÕs oral language is changing.¥ The items can be used to evaluate whether a new teaching programme is having any effect. Change can be captured over two points of time.¥ if the school has introduced some new or special instruction, Biks and Gutches can be used to evaluate its effectiveness. Results could poing to the rate and kind of change that has occurred as a result of special attnetion.¥ for children who speak a dialect of English the test can answer questions like this. Has the childrenÕs control over the rules for inflections of the standard dialect increased?Children usually learn and us both school and ÔhomeÕ versions of English and they know ehen to use either version. Sometimes the non-standard usage dominates, and this can have consequences for school assessments in standard English. Compare the test and retest scores to see the rates of change and any persistent problems.The items in Biks and Gutches were designed for the 5 to 7 year old age group but have been used successfully in research with children up to 10 years old.
