Objective: Regarding a number of outstanding issues in orienteering teaching of males in colleges and universities, I discuss the value and effects of multimedia technology when applied in orienteering teaching as a selective course. Methodology: For the research subjects of Class 1 (as an experiment class with 32 persons) and Class 2 (as the comparison class with 33 persons) of Jinggangshan University, which entered the university in 2009, and which took the selective orienteering course, the literature method, interview method, measurement method, comparison method, questionnaire method and mathematical statistic method were used to conduct an empirical study over the scores of the students in 100m run, 1000m run, orienteering theory, and 100m orienteering. Result: Compared with its scores before the experiment, after the experiment, the experiment class scored 0.45s less in 100m run (P=0.02< 0.05); 21.32s less in 1000m run (P=0.000< 0.01); and 29.05 points less in orienteering theory (P=0.000< 0.01). Compared with the comparison class, after the experiment, the experiment class scored 5.7s on average in 100m orienteering (P=0.000<0.01). Conclusion: Both the multimedia-assisted teaching and the traditional teaching can greatly improve the male students’ scores in 100m run, 1000m run and orienteering theory. However, the multimedia-assisted teaching does better to improve their scores in 100m run and 1000m run, and extraordinarily better in orienteering theory, than the traditional teaching does. Moreover, it can greatly increase their scores in 100m orienteering, with fewer errors and obvious effectiveness. If properly applied, the multimedia-assisted teaching will stimulate the interest of students, so that they can better learn and understand orienteering-related knowledge within a shorter period of time. Such teaching technique is worth spreading.
