This study explores the effects of interdisciplinary education on engineering students by observing students' competencies before and after the programme.

The effects of interdisciplinary education were studied over three years through the use of a survey to test the social competencies of organisational life and the interdisciplinary competencies of college students. A total of 5,185 responses were collected from engineering students who took part in interdisciplinary education programmes. The survey was conducted during weeks 3 and 14 of each semester, and a comparison test was used to reveal any changes.

Among the 12 competencies developed or adapted, leadership significantly improved during all six semesters. Analytical thinking, interpersonal competency, professional attitude, global-mindedness, and creative attitudes also improved in some of the semesters.

It was not possible to control for the effect of classes that students were attending in addition to the targeted interdisciplinary class. However, this study was able to examine empirically the improvement of competencies for future engineers, and its findings provide a basis for future researchers to elaborate on other competencies as well.

The study recommends competencies needed by engineers working in the Fourth Industrial Revolution, examining the effects of interdisciplinary education on competency development. It contributes to strengthening the current trend in universities that seek to reform interdisciplinary education by empirically verifying its effectiveness.
