Staff-student interactions in a physiology laboratory class: What do they involve and are they important?

Although considerable staff resources are often allocated to the teaching of undergraduate laboratory classes, there is a paucity of discussion regarding the extent and substance of the staff-student interactions that occur within classes and also whether these interactions benefit student learning in any way. Performed across four undergraduate laboratory sessions, this exploratory study aimed to quantify the interactions in terms of frequency, duration, and initiation of interactions, as well as gathering staff and student perceptions of the impact of the interactions. Staff gathered descriptive data by completing an observation checklist after each interaction and also provided their own perceptions of the interaction focus and outcome. Student perceptions were collected using an online survey after each class. Staff perceived that the most frequent achievement of the interactions was to enable students to progress with work. However, students’ perceptions suggested that staff may underestimate the impact of staff-student interactions on conceptual learning. The most striking findings were the students’ perceptions of the impact of interactions on their affective domain. On average, 93% of students agreed that when staff take an interest in their work, it motivates them to work hard, and 78% agreed that interactions with staff made the classes more enjoyable. With evidence that positive affect such as enjoyment is positively associated with aspects of learning, this is a salient finding. The study underscores the value of staff availability within the laboratory class and provides impetus to reevaluate how we perceive these interactions and their impact on student learning.
