The study is designed to find out the effect of internet - base tools on performance of senior secondary school students in biology in Kaduna state. The study try to establish the computer skills of students to determine if there is any significant difference in the performance of learners when exposed to the traditional approach and those exposed to learning Biology with the Internet - Based Learning Tools. The research design is experimental study. Four schools were randomly selected, two schools were urban while the other two were rural schools, and two also out of the selected schools were private schools while the two were public schools in order to determine school type and location. One of the schools was boys only while the other school was girls only to determine gender, 100 students were used for the experimental study, twenty five students each in a class. The pre-test post-test control group design was carried out. The experimental group was exposed to a blend of three approaches which includes direct teaching with the internet tool integration, while control group had the traditional method. The t -test analysis of the post test revealed that there is a significant difference in the performance of learners taught using the Internet - based learning tool. The use of the Internet - Based Learning Tools can make a significant difference in the performance of learners in Biology as compared to the traditional chalk and talk approach. Those in urban areas have more advantages than those in rural areas in terms of availability and easy access to the internet facilities which enhances their performance. Both there is no differences in the performance of both Male and Female Biology Students with the integration of Internet -based learning tools. Subject combination has great influence on the performance of the students with the integration of the internet - based learning tools. The Internet - Based Learning Tools has significant effect on the students performance in Biology teaching, the education stake holders in Kaduna state are to ensure that learning becomes fully blended with the Internet - Based Learning Tools
