"Key Words with Peter and Jane" uses the most frequently met words in the English language as a starting point for learning to read successfully and confidently. The Key Words reading scheme is scientifically researched and world renowned. "Book 12c" provides the link with writing for the words used in "12a" and "12b". Once this book has been completed, the child has finished the reading scheme. "The Key Words with Peter and Jane" books work because each of the key words is introduced gradually and repeated frequently. This builds confidence in children when they recognise these key words on sight (also known as the 'look and say' method of learning). Examples of key words are: the, one, two, he. There are 12 levels, each with 3 books: a, b, and c. "Series a": gradually introduces new words. "Series b": provides further practise of words featured in the 'a' series. "Series c": links reading with writing and phonics. All the words that have been introduced in each 'a' and 'b' book are also reinforced in the 'c' books.
The Demand forecasting is one of critical reference by top managers to make the strategy decision for future investment. The copper clad laminate (CCL) is the key material for print circuit board (PCB) and it can apply for consumer, computer, LCD, communication, automotive, aero space, medicine and defense application. The total global sale for PCB in 2008 is US$ 48.2 billion. In this research, we use grey model GM(1,1), rolling grey model (RGM) and Bass diffusion model to analysis global CCL market by six market segments –paper, composite, FR- 4, FR-4 High Tg, FR-4 halogen free, Specialty between 2001-2008. The forecasting accuracy of global CCL market by six market segment was evaluated along with mean absolute percentage error (MAPE). In this study, Bass diffusion model MAPE outperforms the others two models GM(1,1) and RGM for this global CCL market forecasting analysis and is recommend for global CCL market forecasting analysis.
