|VI. EVALUATION OF THE FINAL MANUSCRIPT|
It is recognized that school textbooks are one of the factors which determine the effectiveness of the teaching and learning process in school. They do, therefore, have a positive impact on the yield of educational systems. For this reason their quality is of the utmost importance so far as their relevance to the objectives and content of curricula is concerned and their value as a method of learning and acquiring knowledge.
Before the production of school books enters into the actual production phase, the final manuscript has to be evaluated to ensure that the text offers all the guarantees of quality and corresponds to learning needs.
Whilst it is being written, parts or successive chapters of the text are submitted to readers for assessment: This enables a partial evaluation of the manuscript to be made and permits the author to correct the text or make necessary revisions to improve its quality. However, only when the final manuscript is submitted can a complete and detailed evaluation be made.
