The Role of the Teacher

Despite the popular belief that fun has a positive impact in learning contexts, empirical research on fun in the classroom has been limited. To extend research in this area, the goal of this study was to develop and validate a new scale to assess fun in the classroom and examine its relationship with student engagement. The multi-stage scale development effort resulted in a two-dimensional measure, including fun activities and fun delivery. Fun activities reflect a variety of hands-on exercises and ways to promote social involvement among students. Fun delivery is more instructor-focused, including the use of humor, creative examples, and storytelling. Interestingly, fun delivery, but not fun activities, was positively related to student engagement. These findings suggest that not all fun is equal and highlight the need for additional research to validate the impact of fun on meaningful student outcomes.     

Swimmers’ Compliance to Training as a Function of Observation: A Pilot Study

While seductive details are enjoyable, they are unimportant content or activities intentionally inserted to make class fun and interesting. The purpose of this study was to examine the effect of seductive details on students' learning of net games in physical education. Participants were 240 middle school students. A videotaped lesson example named “outfox your opponent” was used as the stimulus, and a 2 x 3 (condition x grade) factorial analysis was designed. The results showed that seductive details directly interrupted students' recall of important learning content and transferring problem solving in learning net games. It is suggested that the function of seductive details on learning should be reconsidered when designing effective motivational strategies in physical education.
