Abstract Previous research has demonstrated that computer experience has a positive impact on computer self-efficacy. However, little or no research has investigated the unique influence of specific types of computer experiences or knowledge on computer self-efficacy beliefs. This study examines the influence of eight types of computer experiences on computer self-efficacy. The results indicate that experience with computer programming and graphics applications have strong and significant effects on computer self-efficacy beliefs, whereas experience with spreadsheet and database applications demonstrated weak effects. The results offer useful insights into designing training courses and educational programs to enhance computer self-efficacy beliefs.
