Some evidence suggests that attitude toward computer-based instruction is an important determinant of success in online learning. We sought to determine how comfort using computers and perceptions of prior online learning experiences have changed over the past decade, and how these associate with learning outcomes.
Each year from 2003-2011 we conducted a prospective trial of online learning. As part of each year's study, we asked medicine residents about their comfort using computers and if their previous experiences with online learning were favorable. We assessed knowledge using a multiple-choice test. We used regression to analyze associations and changes over time.
371 internal medicine and family medicine residents participated. Neither comfort with computers nor perceptions of prior online learning experiences showed a significant change across years (p > 0.61), with mean comfort rating 3.96 (maximum 5 = very comfortable) and mean experience rating 4.42 (maximum 6 = strongly agree [favorable]). Comfort showed no significant association with knowledge scores (p = 0.39) but perceptions of prior experiences did, with a 1.56% rise in knowledge score for a 1-point rise in experience score (p = 0.02). Correlations among comfort, perceptions of prior experiences, and number of prior experiences were all small and not statistically significant.
Comfort with computers and perceptions of prior experience with online learning remained stable over nine years. Prior good experiences (but not comfort with computers) demonstrated a modest association with knowledge outcomes, suggesting that prior course satisfaction may influence subsequent learning.
一些证据表明，对基于计算机的教学的态度是在线学习成功的重要决定因素。我们试图确定在过去十年中，使用计算机的舒适度以及对先前在线学习经历的看法是如何变化的，以及这些与学习成果有何关联。
从2003年至2011年，我们每年都进行一项在线学习的前瞻性试验。作为每年研究的一部分，我们询问医学住院医师使用计算机的舒适度以及他们之前的在线学习经历是否良好。我们使用多项选择题测试来评估知识。我们使用回归分析来分析关联和随时间的变化。
371名内科和家庭医学住院医师参与了研究。多年来，使用计算机的舒适度和对先前在线学习经历的看法均未显示出显著变化（p>0.61），平均舒适度评分为3.96（满分5分=非常舒适），平均经历评分为4.42（满分6分=强烈同意[良好]）。舒适度与知识得分无显著关联（p = 0.39），但对先前经历的看法有显著关联，经历得分每提高1分，知识得分提高1.56%（p = 0.02）。舒适度、对先前经历的看法和先前经历次数之间的相关性均较小且无统计学意义。
在九年时间里，使用计算机的舒适度和对在线学习先前经历的看法保持稳定。先前的良好经历（而非使用计算机的舒适度）与知识成果显示出适度关联，这表明先前课程的满意度可能会影响后续学习。
