This study aims to design multimedia materials to be used in career counseling and to test
their effects on self-efficacy and learning. Multimedia Learning Theory and Cognitive Load
Theory were used in the study as a theoretical framework. The students were provided to
recognize their personality traits (interests and abilities) and almost 50 professions in the light
of the Holland's Theory. 68 eight graders (34 experimental, 34 control) took part in the study.
A statistically significant increase in the career decision-making self-efficacy scores was
found for the students in the experimental group who received the multimedia training.
Material evaluation form revealed that the students in the experimental group found the
material useful and effective. The learning test results suggested that the content presented in
the materials was learned well. Based on these results; the video materials that allow
individuals get to know themselves and professions more closely can be used as an effective
way in the career counseling process.
