This study investigated the adequacy of physics and
chemistry textbooks used in Senior Secondary Schools in Nigeria using Owerri
municipal as case study. Five research questions guided the study. The sampled
textual materials were the three recommended physics and chemistry textbooks.
Twenty six physics teachers and thirty chemistry teachers from ten public
secondary schools in Owerri municipal, Imo State were used. The evaluation of
these text books were carried out using the modified form of 8 – point quantitative
approach to content evaluation of science text books (QACEST) and teacher’s
perception rating scales (TPRS). The modified form of the 8 – point QACEST was
used to answer research questions 1 to 4 while research question 5 was answered
using teacher’s perception rating scale. The result revealed that while all the
text books were adequate in terms of content and study questions inadequacies
exist in some of the texts in the areas of learning activities, illustrations
and teacher’s perception. This simply implies that no single text books have
completely met the requirements of the new physics curriculum and chemistry
curriculum while comprehensive chemistry could serve as good as support to
other textbooks. However, teachers should not adhere to a particular text book
but rather should expose their students to a variety of text books depending on
the goal or aim of the lessons.
