This paper presents the validation process and results of a study to develop a measure for assessing students’ attitude towards learning embedded systems design course. The instrument content validity was verified, and a pilot test was performed to assess the instrument reliability. The construct validity was established using Rasch Analysis and WINSTEPS 3.92.1. Our results showed that all the instrument items fit the Rasch measurement model with acceptable fit index (0.6-1.4) and demonstrated excellent consistency, with a reliability alpha of 0.98 and 0.87 for items and persons respectively. The results showed that the survey instrument was reliable and valid. This study also revealed that most students developed some negative attitudes in the process of learning embedded system design.
