Abstract
The study aims to determine teachers’ experience, educational qualification and mastery of difficult concepts in physics. An ex-post facto research design was used for the study. Two research designed questions and two hypotheses were posited and tested at 0.05 levels of significance. Influence of Teachers’ Experience and Educational Qualification on Mastery of Difficult Concepts in Physics Questionnaire (ITEEQMDCPQ) was designed using a 5-point Likert scale. The reliability of 0.78 was obtained using the Pearson Product Moment Correlation Coefficient. The questionnaire was administered purposively to 246 senior secondary school Physics teachers, and 240 was retrieved from 98 senior secondary schools in the area of study. Data was analyzed using One-way Analysis of Variance for a single mean. Results of the analysis shows that teacher experience and educational qualification has a significant influence on mastery of difficult concepts in Physics, based on the findings it was recommended that teachers should undergo more training programs to gain more experience in teaching to enhance their mastery of concepts. Teacher should be encouraged to further their education to acquire higher educational qualifications.
