在正确的时间寻求正确水平的帮助可以支持学习。然而，在网上解决问题的环境中，它仍然是不完全清楚的寻求帮助的策略是可取的。我们使用来自38名高中生的细粒度数据，这些学生与几何认知导师一起工作了2个月，以更好地了解特定求助模式与学习之间的关联。我们评估了学生在辅导问题的每一步上的求助行为与他们在需要相同技能的后续步骤上的成功之间的关系。在技能水平上分析学习使我们能够比较单个学生的不同求助模式，控制学生之间的差异。总的来说，在具有挑战性的步骤上寻求帮助与富有成效的学习有关，过度使用帮助与较差的学习有关。然而，与许多寻求帮助的理论相反，避免帮助（和反复失败）与更好的学习有关，而不是在学生先前知识不多的步骤上寻求帮助。这些结果表明，新手学习者可能会受益于从事解决方案的尝试之前，他们可以得到帮助的意义。使用当地的学习措施的方法上的好处进行了讨论，并得出其他形式的生产失败的问题解决的比较。
Seeking the right level of help at the right time can support learning. However, in the context of online problem-solving environments, it is still not entirely clear which help-seeking strategies are desired. We use fine-grained data from 38 high school students who worked with the Geometry Cognitive Tutor for 2 months to better understand the associations between specific help-seeking patterns and learning. We evaluate how students' help-seeking behaviors on each step in a tutored problem are associated with their success on subsequent steps that require the same skills. Analyzing learning at the skill level allows us to compare different help-seeking patterns within a single student, controlling for between-student variations. Overall, asking for help on challenging steps is associated with productive learning, and overusing help is associated with poorer learning. However, contrary to many help-seeking theories, avoiding help (and failing repeatedly) is associated with better learning than seeking help on steps for which students have low prior knowledge. These results suggest that novice learners may benefit from engaging in solution attempts before they can make sense of given assistance. Methodological benefits for using local measures of learning are discussed, and comparisons are drawn to other forms of productive failure in problem solving.
