The periodic updating of the teaching and learning of Mathematics as a core subject in both the basic and secondary school levels for the generation upcoming is a necessity born out of its importance. To uphold this idea, the magnitude of the teachers’ computer usage in the teaching of Mathematics is quite germane, especially for a twenty-first century educators in which every human activity is coated with technology. Hence, this research seeks to investigate the extent of the involvement of Mathematics teachers in the use of technology in the teaching and learning of Mathematics and to establish the impact of digitalization on the performance of students in Mathematics. The population for the study consists of all the Senior Secondary School II (SSSII) students in Ekiti State and their Mathematics teachers. The design adopted a mixed approach of qualitative and quantitative techniques, these are; survey and quasi of pretest, posttest control groups designs. The sample consists of all the SSSII Mathematics teachers of the selected schools numbered to 11 with the 101 selected SSSII students across the three Senatorial Districts. Multistage sampling was adopted to select the schools and the students. Self-prepared questionnaire tagged “Teacher’s Technological Involvement Inventory (TTII) was used to collect data from the teachers. Mathematics Performance Test (MPT) was administered on the learners to generate data. The instruments were validated by experts in the field of Test and Measurement and also in the field of Mathematics education before usage. Observation showed that a large number of teachers in secondary schools did not digitalise the teaching of Mathematics. Also, it was revealed that the use of technology in the teaching of Mathematics as experimented improved students’ performance in Mathematics. Hence, it was recommended that in-service training should be organized for teachers on the digitalizing teaching. Teachers should be encouraged to teach Mathematics using mobile phones.
