Well-structured business studies textbook provides enjoyable episodes of knowledge creation which promotes achievement learning outcome for sustained academic results. Business textbook represents potentially implemented curriculum as its vehicle through which intended curriculum is availed to learner encouraging achievement of learning objectives. However, adopting methodology that does not facilitate achievement of specific objectives may limit knowledge construction degrading learner’s mean score. The study adopted is exploratory research design. Data collected were both quantitative and qualitative. Quantitative data were analyzed through counts, percentages, means, standard deviations and Chi square tests while Qualitative data were analyzed using content analysis. Cross tabulation results further indicated that teaching methods significantly influence quality of textbook implying that appropriate teaching methods supports achievement of learning. It was also found that presentation, visuals and differentiated instruction influence quality of instruction content encouraging learning. Therefore, it is recommended that teaching method selected should be learner centered to accelerate learning.

The study adopted exploratory research design through qualitative approach to data collection and analysis. Content analysis was used for data analysis. Summary of content analysis showed that textbook revision was necessary in ensuring quality textbook. Further analysis showed that Process of appraisal, Scope of curriculum, Complexity of syllabus influence quality of instruction content in textbook encouraging learning and acquisition of skills. Therefore, it was recommended that content of business studies textbook to be relevant to learner’s cognition to accelerate learning.

Meticulously developed business studies textbook facilitates individualized learning contributing to the achievement of learning objectives even in the absence of the teacher. Think-pair and share is accelerated as learners are likely to discuss amongst themselves new knowledge acquired through business studies textbook hence boosting learner enthusiasm in construction of knowledge. However, instructional information in business studies textbook may not necessarily facilitate realization of specific objectives where policy governing textbook selection, acquisition and review is inadequate and missing full implementation. Nevertheless, in an instance where the instructional policy guiding textbook selection, acquisition and review are adhered to, the quality textbook is availed to learners in secondary schools in Kenya. This study adopted an exploratory research design through qualitative approach to data collection and analysis.
