    Based on the data obtained from the textbooks, the learning activity index LAI was calculated and presented in Table 2. Note that A represents number of sentences requiring the learner to perform some activity while P is number of sentences requiring the learner only to receive information with no other activity.

    Table 2: Bajah et al 30 0. This implies that none of the five chemistry textbooks contained learning activities as specified in the core — chemistry curriculum. Research Question 3 How appropriate are the chapter summaries of the chemistry textbooks in use in Nigeria Secondary Schools? In Table 3 Js is number of statements in the summary which re-present major points covered in the chapter, Jc is number of major points covered in the chapter, Ns is number of statements in the summary which re-present minor points covered in the chapter while Nc is number of minor points covered in the chapter Table 3: The results reveal that all the five chemistry textbooks evaluated are within the acceptance range of chapter summary.

    Research Question 4 How adequate are the study questions of the chemistry textbooks in use in Nigeria Secondary Schools? The data obtained from the textbooks were used for the computation of the study questions index SQI. The computation of the SQI was based on the study questions found in each of the five chemistry textbooks evaluated. The results are presented in Table 4.

    Note that T is number of questions that require students to engage in real thinking while R is number of questions that require students to merely recall knowledge. Table 4: Bajah etal 76 25 0.

    This implies that all the textbooks evaluated contained appropriate study questions. Research Question 5 What are the illustrations index of the chemistry textbooks in use in Nigerian secondary schools?

    The data obtained on illustrations found in each of the five chemistry textbooks evaluated were used for the computation of the illustrations index ILI. The results are presented in table 5. Note also that La is number of illustrations requiring the learners to perform some activity while Lb is number of illustrations requiring the learners to only view.

    Table 5: Bajah etal 56 69 Oyeyiola 47 52 Research Question 6: What is the Readability Index of the chemistry textbooks in use in Nigerian secondary schools? The mean readability scores of the five chemistry textbooks evaluated were computed and presented in table 6. Table 6: Bajah It is expected that all the textbooks be very readable.

    Chemistry for senior secondary certificate by V. Research Question 7 What is the under representation population index of the chemistry textbooks in use in Nigeria secondary schools? The data obtained from the five chemistry textbooks on under-representation of populations were used to answer research this question.

    The results of the data analysis are presented on table 7. Table 7: BK 3 by Bajah 16 0. Research Question 8 What is the teacher perception index of the chemistry textbooks in use in Nigeria secondary schools?

    The results obtained are presented on table 8. Table 8: The range of acceptance of the value is 3. Any value below 3. The grand mean scores for the five chemistry textbooks evaluated are within the acceptance range of 3. Although the teachers agree that these textbooks are helpful to them in their instructional delivery they failed to score them very high.

    As we can see the teacher perception indices for each of the five textbooks are slightly above 3. Summary Results presented for this study reveal that only three out of the five chemistry textbooks evaluated are within the acceptance range of topical coverage. It is necessary to note that Chemistry for senior secondary school certificate by V. Oyeyiola and pure chemistry for West African schools by B.

    Bajah was adjudged to have attained minimum standard, there is a serious need to upgrade of textbooks. The study also reveals that none of the five chemistry textbooks evaluated are within the acceptance range of learning Activity coverage. Furthermore, the evaluation shows that all the five chemistry textbooks evaluated are within the acceptance range of chapter summary.

    In terms of study question result of data analysis reveals that all the five chemistry textbooks evaluated are within the acceptance range of study questions index and also that their illustrations are very adequate.

    Finally, although the teachers agree that these textbooks are helpful to them in their instructional delivery they failed to score them very high. As shown in Table 8 the teacher perception indices for each of the five textbooks are slightly above 3.

    Recommendations Based on the findings and conclusions of this study, the researchers made the following recommendations 1. Scientific knowledge and discoveries are increasing everyday; it is necessary that all the chemistry textbooks in use in secondary schools in Nigeria should be revised periodically. Chemistry textbook authors and publishers should consult core-curriculum in chemistry when writing and publishing their books. This will help them to choose topics, performance objectives, contents and learning activities from the specified core-curriculum.

    This would help the authors to achieve high topical coverage, learning activities, study questions and chapter summaries indices. References Ababio, O. Nigeria edition Altbach, P. Eds Textbooks in the third world: Policy, content and context. New York: The researchers found this design useful because it involves making value judgment about chemistry textbooks in use in secondary schools in Nigeria.

    The instrument that was used for data collection is the 8 — point quantitative evaluation model for science textbooks. It was developed by Emerole in The 8-point model evaluates science textbooks using the following indices:- i.
