The textbooks that were assessed by the selected chemistry teachers are:
1. Bajah, S. T., Teibo, B. O., Onwu, G., Obikwere, A. (1997, and 1992): Senior secondary chemistry textbook 1, 2 and 3. Longman Nigeria PLC.
2. STAN (2006, revised edition): Chemistry for senior secondary schools. Heinemann Education Books (Nig) PLC.

8. Significance of the Study
The study would be beneficial to teachers, students, textbook writers, curriculum planners and Ministry of Education.
The results might sensitize teachers to see the need for assessing textbooks and make necessary suggestions to officials from Ministry of Education as guide in selecting textbook.
The findings might be significant to the students in the selection of ‘good’ textbooks that will be in line with the syllabus so as to achieve purpose of chemistry education.
The study might keep the curriculum developers such as Nigeria Educational Research and Development Council (NERDC) abreast of the need for contents, materials, learning activities to be deliberately selected and organized so as to ensure the attainment of specific objectives of learning chemistry.
The study might guide the educational service divisions of the Federal and State ministries of education, Local Government Area officials in charge of textbook selection in choosing more relevant chemistry textbooks so that students’ performance in chemistry could improve.

10. RESEARCH METHODOLOGY
Research Type
Descriptive research of the survey method was adopted in this study to describe and summarize the data.

11. Sample and Sampling Techniques
The population for this study were made up of all secondary school chemistry teachers in Kwara State.
Stratified random sampling technique was used to sample 141 chemistry teachers from 101 purposively selected secondary schools across the state.
Qualification and year of teaching experience of the chemistry teachers of the selected schools were used in classifying them into: qualified, unqualified, experienced and less experienced chemistry teachers.
The selected teachers assessed the following selected chemistry textbook: (1) STAN (2006, revised edition): Chemistry for senior secondary schools. Heinemann Education Books (Nig) PLC. (2) Bajah, S. T., Teibo, B. O., Onwu, G., Obikwere, A. (1997, 1990 and 1992): Senior secndary chemistry textbook 1, 2 and 3. Longman Nigeria PLC.

12. Research Instrument
The research instrument that was used for this research work is a researcher-designed questionnaire prepared for teachers; it is called Chemistry Teachers’ Questionnaire (CTQ).
The questionnaire consists of three sections: A, B and C. Section ‘A’ was meant to collect the biographical data of the teachers. Section ‘B’ dealt with the textbook used in the sampled schools and section ‘C’ consists areas that will assess the readability of the two selected textbooks base on the criteria used.

13. Instrument validation
The instrument was given to three experienced and qualified chemistry teachers at the secondary level and lecturers (chemistry Educators) at Kwara state College of Education, Ilorin for scrutiny.
The final draft was later passed to the project supervisor for final comments and suggestions before it was produced.
The reliability of the instrument was determined through the administration of questionnaire twice on 20 chemistry teachers.
Using Pearson Product Correlation Coefficient of the two administration, a reliability of 0.80 was obtained

14. Procedure for Data Collection
The researcher sought the official permission and the cooperation of the school management where teachers were involved.
The researcher personally administered the questionnaire.
A two week was given and this made respondents had enough time to respond correctly to the statements contained in questionnaire.
The completed questionnaires were collected from respondents for analysis after two weeks.
