The objective of the study was to determine if microlearning courses were effective at building the feeling of confidence and accuracy in the work of dairy personnel. Three courses on colostrum management were developed with a cloud-based software. The courses had 4 topics (objectives, standard operating procedure, background information, quiz), a contact time of 10 min, and were accessible via PC or smartphone. With a 12-item survey, we collected relevant data on course perception and feedback. Learner’s experiences such as access, page visits, time spent, and completion were observed with a learning management system. From February to May 2018 interested farms (convenience sample) were contacted by email or Whatsapp and invited to participate free of charge. The email contained an introduction, the URL, and instructions on how to launch the course. On the first 3 screens an informed consent of the participants was obtained, a disclaimer shown, and the navigation explained. The menu page provided buttons linked to the 4 topics. A total of 80 people (employees, trainees, herdsmen) were invited of which the majority (50 to 62%) participated. Overall, the course quality was rated high (1.4 on a 5-point scale; 1 being the best). The overall response rate was 40% and almost all participants accessed the SOP within the course (i.e., 92, 90, and 96% in the first, second, and third course, respectively). Most employees reported that after the training they felt more confident to conduct the task described (77%) and were convinced to work more accurately (89%). Actual contact time was 5 to 7 min longer than the perceived contact time indicating a high level of engagement. Furthermore, most participants confirmed that repeating relevant steps even of a simple and well-known task was also worthwhile. Two thirds of the participants took the courses in their leisure time and one third accessed the courses more than once. Almost all participants (89%) accessed the background information (“why should I do it”). The majority (55% to 92%) of the participants provided feedback in open text fields. User generated data can be used for future course developments and to improve employee engagement.
