The school system in Oman faces a problem in educating students in integrated science, technology, engineering and mathematics activities. This statement, in part, stems from science teachers' preparation programs. This study was aimed to close a research gap in Oman by investigating science pre-service (trainee/student) teachers' self-efficacy beliefs for teaching science by using engineering design processes. A self-efficacy beliefs for teaching as engineering design questionnaire was developed and utilized for measuring science trainee teachers' self-efficacy beliefs for teaching science by engineering design methods. A descriptive approach with quantitative data collection was used as a design of the study. A sample of 73 students at Sultan Qaboos University participated voluntarily. The results showed that student teachers believed themselves to be highly successful in teaching science. BSc program trainee teachers had higher perceptions of themselves as highly successful in teaching science with regard to personal self-efficacy beliefs and in two scales in outcome expectations for science teaching in the new manner than did trainee teachers with a teacher qualification diploma. Regarding gender and major, there was no statistically significant difference in trainee teachers' self-efficacy beliefs. Contributions to research and future perspectives of the study findings on improving science teaching and learning are discussed.

MBV provides excellent long-term results for selected patients with MS. The long-term outcome after this procedure can be predicted from baseline clinical and echocardiographic characteristics.
