Gary, why do you feel you struggle? Fun is not always the magic formula but engaging tends to be the more common thread. Engaging could be using a fun assignment but can also be getting your students to think critically or creatively. The more your students feel they are involved and embedded the more they will get out of the experience. What research have you conducted on student engagement and impact on teaching and learning? As an instructor we all must continually be learning new techniques and finding different ways to engage our students. James Jackson
