This study designed a correlation analysis method that focused on textbook content and objectives. Based on a mechanism similar to blind test, this method used a team of experts to survey texts, pictures, charts, and instruction activities employing a comprehensive and interpretative approach, converting textbook content into instruction objectives and competence indicators. Another team of experts further compared the instruction objectives and competence indicators with the original instruction objectives and competence indicators listed in the textbooks. Using the graphics and data, the semantic association of the two sets of instruction objectives and the statistic correlation of the two sets of compe-tence indicators are presented for further discussion and examination. The ap-plicability of this analysis method was inspected in accordance with features particular to this research method and requisites that are to be met in method design, and the processes and results of empirical trial. The utility, objectivity and conciseness of this analysis method could be verified. However, some co-ordination with textbook accreditation and evaluation authorities were required to enhance the feasibility in terms of time and finance.
