On the Impact of Nonverbal Signaling in Online Teaching

Maria Osipenko, Kathrin Heller



Strategies that optimize teaching style and enhance teaching impact, especially in online format, have captured attention of researches in various fields. In an online lecture, instructor may communicate (e.g. via highlighting) some important concepts in script nonverbally, in order to draw attention to particular important concepts for a topic. The so called signalling or cueing strategies, where visual (text-based or picture-based) cues draw attention to relevant parts of the material, come into play. In the present paper we address the following research question: Do different usage patterns of nonverbal signalling cues of course instructor as highlighting words and formulas, as well as making notes in lecture materials have impact on learning success in online format? In our retrospective analysis of lecture notes and the contained nonverbal signaling cues against the probability of passing exam questions in quantitative online courses, we were able to confirm a significant positive effect of highlighting and color coding of formulas and a significant negative impact of using many signaling tools simultaneously. The results are promising for recommending signaling strategies in teaching of quantitative disciplines.
