In the BOL group, a 45-minute online training session was held. Afterward, a virtual channel was formed and at a specific time, videos were shared for 5 days for further study and short questions were asked for group discussion. In the control group, two 2-hour online training sessions were held once a week. The knowledge and performance of nurses were evaluated before the intervention as well as two and four weeks after the intervention.
