This study explores the effects of learning style, age and gender on preferences for online educational activities. David Kolb's Experiential Learning Theory (Kolb, 1984) is used as a lens to examine the responses of online learners to five types of educational activities. Results indicate that learning style influences preference for learning activity. The relationship is stronger among adults than among children aged 10-13 (middle school). The four learning styles were not evenly distributed. “Practical” (likes to solve problems and find solutions) was the most frequent style among both children and adults (37%). “Creative” (enjoys brainstorming and open-ended exploration) was the least frequent (8%). These data have particular relevance to the development of educational activities, suggesting that open-ended exploration with “no right answers” may not be the most satisfying and appealing approach for many learners. The results of this study provide new insight into online audiences and can help developers of multimedia activities to create experiences that will appeal to all kinds of learners.
