If an instructor delivers a lecture and no one learns anything, did teaching really take place? Is this one of your recurring nightmares? I know I spend a lot of time assessing the effectiveness of my teaching and this question really resonates with me. I just finished a good article by Alla Kushniryk and Kenneth J. Levine about multitasking (or switch-tasking as some of the literature describes it). It validates what others have discovered as well; basically that it is very difficult for anyone to listen well and write good notes that will allow them to learn. They write, "It was found that multitasking significantly decreased performances on both the listening and writing tasks. The experiment also uncovered that the degree of social presence did not affect students’ performances on the listening or writing tasks in the learning environment. The perceived degree of social presence was the same in the virtual- and live-presenter groups." The social presence portion of their findings is crucial information for our eLearning colleagues. Teaching in an online or hybrid environment presents its own challenges but this research notes that learning can be done well even when the mode of delivery isn't in the traditional face-to-face version. The scientists did add, "In the virtual-presenter condition, the participants of the study might consider the listening task as being secondary and the writing task as being the most important." Understanding how learners perform in different settings is crucial if we are to deepen our understanding of effective teaching. This study certainly helps but more should be done to discover what works best in 21st century learning environments.
