  This paper presents an analysis of two pre-registered experimental studies
examining the impact of `Motivational Interviewing' and `Directing Style' on
discussions about Sustainable Development Goals. To evaluate the effectiveness
of these communication styles in enhancing awareness and motivating action
toward the Sustainable Development Goals, we measured the engagement levels of
participants, along with their self-reported interest and learning outcomes.
Our results indicate that `Motivational Interviewing' is more effective than
`Directing Style' for engagement and interest, while no appreciable difference
is found on learning.
