The recent development in modern instruction technology (MIT) methods and equipment warranted for studies to examine their effects on students, teachers, and the education system in general. This study examines the effects of MIT on students’ critical thinking skills in Agriculture vocational courses in Nigeria. The methods and equipment used were identified, and the effect of teachers’ usage behaviour was assessed. A survey approach was adopted, using questionnaires for data collection. The descriptive, correlations and multiple regressions were carried out using SPSS. The result of this study indicates that the most commonly used equipment is electronic whiteboard, while the least are electronic tablets and laptops. Cooperative learning is the most commonly used methods while games and online instruction are the least. There is a moderate positive correlation between MIT methods and the students’ critical thinking skill, but a very weak positive correlation between MIT equipment and students’ critical thinking skill. There is statistically significant contribution of methods to student’s critical thinking, but insignificant method usage behaviour. Therefore, it is concluded that government should incorporate the provision and effective utilisation of MIT equipment and methods in the national education policy. School managements should emphasise the use of MIT methods and review curriculum to improve teachers’ skills in MIT usage. Teachers should utilise the available MIT equipment and method along with their skills for an effective delivery of lessons. Similarly, the students should be encouraged to appreciate the available methods and the equipment, and use them effectively
