Abstract: This study was meant to measure the effects of the use of scientific calculators on pre-service teachers’ computational skills. It specifically sought to find out the impact of scientific calculator usage on pre-service teachers’ performance and errors in computational skills. Thirty student-teachers participated in the study. Researchers used interviews, pre-tests, interventions, and post-tests to investigate the impact of scientific calculator use on student-teachers’ computational skills. The study revealed the errors student-teachers made in their computational skills which included errors in parenthesis, approximation, concept application and sequence of operations. As a result, we found that there was a difference between the results before and after the test in terms of the minimum, maximum, mean, and standard deviation and the latter was superior to the former (i.e., the pre-test mean and the standard deviation is 3.90, test after 2.05). The test means and SD are 6.40 and 2.67). The t-test results (29df, t=6.335, p=0.00) also showed that the mean difference was significant at p=0.00. Analysis was performed to determine whether mean differences were statistically significant. This means that scientific calculators had improved the computational skills and abilities of student-teachers, thereby improving their mathematics performance.
