Some Omani science teachers face a challenge in teaching students to deal with learning materials such as texts and pictures. Based on the need for adequate teaching with text-picture material (TPM), this study aimed at investigating the level of teachers' (N = 886) attitudes and motivational orientations--as aspects of their professional competence--toward teaching with TPM and their relations to teacher background variables. The results showed a high level of teachers' attitudes and motivational orientations in teaching with TPM and revealed low directed relations among teachers' gender, teaching experience, and the number of science lessons taught per week in all classes. In addition, the results showed differences in teachers' attitudes and motivational orientations in schools of different levels. The findings of this study contribute to the science education field by adding knowledge on important aspects of teachers' competence for teaching with TPM and their relations to teachers' demographic background in an Arab context such as that in Oman.
