Variation in contributions to teaching by meerkats.

ABSTRACT: Recent evidence from cooperative insect, bird and mammal societies has challenged the assumption that teaching is restricted to humans. However, little is known about the factors affecting the degree to which individuals in such societies contribute to teaching. Here, I examine variation in contributions to teaching in meerkats, where older group members teach pups to handle difficult prey. I show that investment in teaching varies with characteristics of pups, helpers, groups and ecological conditions. Although prior experience in caring for pups did not significantly influence teaching behaviour, younger helpers, which were still investing in growth, contributed less to teaching than older individuals. This suggests that, in common with other cooperative activities, contributions to teaching vary with the costs experienced by individual group members. However, in contrast to other forms of helping in meerkats, I detected no effects of nutritional state on teaching, suggesting that it carries relatively low costs. In species where individuals can potentially gain direct or indirect fitness benefits from facilitating learning in others, low costs divided among multiple group members may help tip the balance towards selection for teaching.

Project description:BackgroundNumerous studies have pointed out the need for better training of healthcare professionals in drug-drug interactions management in order to minimize adverse drugs reactions impacts on patients. The aim of this study was to evaluate the benefits of a blended learning strategy based on peer evaluation (PE) for teaching drug-drug interactions to undergraduate pharmacy students.MethodsThird-year pharmacy students (n = 72) from the University of Limoges were involved in a hybrid teaching using the Moodle platform (2.9 version). After the theoretical lectures, an online activity was proposed to students. Each student submitted a report addressing a clinical case for peer evaluation. Students evaluated the pedagogical approach using an online survey. Quantitative benefits were assessed from students randomly assigned into two groups: PE in pharmacodynamics items (PE-PD) or PE in pharmacokinetics items (PE-PK). During this activity, three marks were given: one from peers for their evaluation work and two from teachers for oral group presentation of the clinical cases and for the final written examination. Statistics were performed using two-tailed unpaired t-test and significance was set for p < 0.05.ResultsOnly a few students (n = 14, 20.6%) were aware of the peer evaluation principle and even less, only one student (n = 1, 1.5%), had already encountered it. Students considered that they benefited from this evaluation (n = 65, 95.6%); from their work being reviewed (n = 62, 91.2%) and that they participated in improving their classmates understanding (n = 59, 86.8%). Peers' allocated marks were similar in the two PE groups (PE-PD = 17.4 ± 1.4; PE-PK = 17.3 ± 1.4). Teachers' marks for oral presentation were significantly lower for pharmacodynamics than for pharmacokinetics items (PE-PD = 15.2 ± 1.2; PE-PK = 16.1 ± 2.1; p < 0.05). The final examination marks were equivalent in both groups (PE-PD = 11.0 ± 2.1; PE-PK = 11.2 ± 1.9).ConclusionsBesides the fact that a major short-term quantitative improvement was not detected, our teaching approach was qualified as being a positive and stimulating learning tool by students.
