Generative
Artificial Intelligence (GenAI) is increasingly recognized for its potential to
improve lesson planning and delivery; however, its integration into secondary
school Biology teaching remains underexplored in Nigeria. Guided by the Technology Acceptance Model (TAM),
this study investigated Biology teachers' awareness, perception, and
utilization of GenAI tools in lesson planning and instructional delivery in
Kaduna State and examined the relationships among these variables. A
descriptive survey design was employed involving a population of 287 Biology
teachers, from which 169 were selected using a multistage sampling procedure.
Data were collected using a 30-item researcher adapted questionnaire that was face and content validated by experts
and yielded a Cronbach's alpha reliability coefficient of .897. Descriptive statistics and
Pearson Product Moment Correlation were used for data analysis at the .05
significance level. The findings revealed low awareness (M = 2.20) and
utilization (M = 1.83,), but a positive perception (M = 3.06). Significant
positive relationships were found among the variables. These findings extend TAM by demonstrating that positive
perceptions alone do not guarantee classroom utilization where awareness and
institutional support are inadequate. The study recommends targeted
professional development and improved institutional support to promote effective
integration of GenAI into Biology teaching
