视觉线索和视频解决方案对概念任务的影响
Effect of visual cues and video solutions on conceptual tasks
摘要：
学习迁移是教育的一个重要目标。然而，学生在解决物理迁移任务时通常会遇到困难，即使他们已经解决了类似的问题。我们调查了使用包含先前解决的问题的详细解释的视频提供的指导是否会提高学生在处理近距离和远距离迁移任务中的表现。我们还调查了视觉线索与视频解决方案的结合是否会进一步提高学生的表现。N=33名学生在代数为基础的物理课参加了一个采访，其中包含两个问题集，每个问题集有一个初始任务，一个培训课程，和一个近和远的转移任务。在训练中，学生要么接受视觉提示，视觉提示和视频，要么只接受视频，这取决于条件。我们比较了三种情况下学生在远近迁移任务上的正确率。
英文摘要：
Transfer of learning is an important objective of education. However, students usually have difficulties in solving physics transfer tasks even after having solved similar problems previously. We investigated if instruction provided using videos containing detailed explanations of previously solved problems will improve students' performance in tackling near and far transfer tasks. We also investigated whether the combination of visual cues followed by video solutions yields further enhancement of students' performance. N=33 students in an algebra-based physics class participated in an interview containing two problem sets each with one initial task, a training session, and a near and far transfer task. For the training, students either received visual cues, visual cues and a video or only videos, depending on the condition. We compare students' correctness rate on near and far transfer tasks in the three conditions.
