This study aimed at investigating the effect of applying integrated Science, Technology, Engineering, Art, and Mathematics (STEAM) approach on motivation among students of grade 10 in a private school in Amman. In this context the researchers used a quasi-experimental method. The sample of this study involved 32 high school students; the individuals of the study were intentionally chosen and distributed randomly into two groups: the control group consisted of 19 students who studied Geography in a conventional way, and the experimental group consisted of 13 students who studied the same content using STEAM approach. To achieve the study goals, the researchers developed an instrument to measure motivation towards learning geography that focused on the following constructs of motivation: Internal Motivation, Grade Motivation, Class Anxiety, Career Motivation, Self-Efficacy, and Teacher Obedience. After verifying its validity and reliability, the instrument was applied on the study sample. The results of the analysis of covariance (ANCOVA) showed no significant difference on motivation in all of its constructs except for (Class Anxiety) which was in favor of the experimental group. The study recommended providing teachers with enough and valuable training opportunities on how to activate STEAM approach to ensure meaningful learning for students and to increase their awareness to future careers including STEAM jobs.
