This research is action research aimed to reveal the effectiveness of using blended learning based on digital games in increasing the motivation of grade-five students towards learning mathematics. The quasi-experimental method was used with thirty-eight grade-five students in Imam Al-Hassan bin Saeed Al-Sahtani Basic Education School for Boys (5-12) in the Sultanate of Oman. The study used two instruments; an educational program based on digital games and a scale of students' motivation toward learning mathematics. The study found that there were statistically significant differences in favour of the post-motivation scale, in which the mean of the scale in pre-motivation scale was 2.73 and the mean of the post-motivation scale was 4.13. There was a difference of 1.4 in favour of the post-motivation scale. Considering the results of the study, the researchers recommended encouraging teachers to use blended education based on digital games and making various interactive activities for students through instructional digital games.

The purpose of this study was to examine the components of change management and their impact on attaining sustainable development objectives. The researcher used a descriptive approach and a questionnaire to achieve this objective. It was evaluated on a sample of (300) government employees. The results indicated the following: In varying degrees, all aspects of change management have a substantial impact on sustainable development. After the change in tasks and after the change in structure, two axes were ranked as the most important. The axis first appeared after the technological shift, and then again after the organizational culture shift. The study also demonstrated that there are numerous obstacles to achieving human development objectives through change management. The administration of Oman is committed to long-term expansion. Among these are the unwillingness of senior leadership to adapt some antiquated processes in some government sector institutions and the lack of diversity in human resource specialties among government sector employees. Through the implementation of certain legislative initiatives and close attention to them, the study recommends that administrative leaders pay close attention to the dimensions of change management in light of current circumstances as one of the most powerful forms of influence.
