<b>加速对视频学习的元分析</b>

对于符合纳入标准的文献，按照以下条目进行编码（见表1）：（1）基本信息。包括作者、时间和样本量。（2）材料语速。明确使用的实验材料的平均语速大小。（3）倍速类型。按照对比试验的材料倍速进行编码。（4）结果变量。将学习效果指标，按照认知负荷、学习满意度、保持测验（对学习材料的记忆和识别程度）和迁移测验（迁移能力）进行编码。For literatures meeting the inclusion criteria, coding shall be conducted according to the following items (see Table 1): (1) Basic information, including authors, publication year, and sample size. (2) Speech rate of experimental materials: specify the average speech rate of the employed experimental materials. (3) Speed-up type: code based on the speed-up ratio of the materials used in the comparative experiments. (4) Outcome variables: code the learning effect indicators according to four categories, namely cognitive load, learning satisfaction, retention test (the degree of memory and recognition of learning materials), and transfer test (transfer ability).
