Abstract
21st century biology is becoming increasingly quantitative, requiring students to master mathematical knowledge for them to fully understand and apply the new emerging biological concepts and skills for socio-economic development. This study, therefore, aimed to determine the factors affecting the integration of mathematical skills into biology curricula at secondary school level in Zambia. Primary data was collected using a quantitative biology assessment test for biology class pupils and survey questionnaires for both biology teachers and pupils. Secondary data was obtained from past biology examinations papers of the Zambia General Certificate of Secondary Education/O-level (GCSE) and the Cambridge University International General Certificate of Secondary Education (IGCSE) for the years 2010 – 2016. The study sample was 140 biology class students and 16 biology teachers selected from 8 secondary schools in the Copperbelt province of Zambia. Statistical analyses using descriptive statistics, one-way ANOVA and factor analysis were conducted using SPSS and Excel. The results of this study revealed a mean pass rate in the quantitative biology test of merely 14.3%, with the lowest mean score (6%) obtained for questions in the higher order cognitive levels of Bloom’s taxonomy. The coverage of mathematics related questions in the national biology examinations was low at 7.1% and 18.9% for GCSE and IGCSE, respectively. Overall the pupils had inadequate skills for tackling quantitative biology questions. The contributing factors for this situation included the lack of quantitative competencies amongst biology teachers and the unavailability of appropriate textbooks to guide teachers and students. The biology syllabi and assessment requirements do not compel teachers to teach mathematical biology. Consequently, students exhibited phobia and a negative attitude towards quantitative biology. Overall, Zambia requires a new educational policy framework that should drive the integration of mathematics and biology throughout the Zambian educational system.
