摘要
微视频字幕作为微视频不可或缺的信息元素,其呈现方式对学习者学习效果具有一定影响。文章通过问卷调查法和实验法,分别探究陈述性和程序性知识微视频中,字幕呈现方式与学习风格两个变量对学习者学习成绩与认知负荷的影响,以期寻求教学视频的最佳字幕呈现方式。研究结果发现:(1)无论哪种微视频,字幕呈现方式都对视觉型学习者的学习成绩影响显著,且“关键词字幕”的学习成绩均为最佳。(2)无论哪种微视频,字幕呈现方式对言语型学习者影响不显著。但从均值来看,陈述性知识微视频中,言语型学习者学习“全字幕+关键词字幕”的成绩较好;程序性知识微视频中,学习“关键词字幕”的成绩较好。(3)不同字幕呈现方式与学习风格对学习者认知负荷的影响均无显著性差异。
Micro-video subtitle is regarded as an indispensable information element of micro-video,and its presentation has certain impact on learner’s learning effect.This paper,through questionnaire survey and experimental method,has respectively delved the influence of two variables,namely,subtitle presentation and learning style,on the students’learning results and cognitive load in the declarative and procedural knowledge micro-videos,hoping to find out the best subtitle presentation of teaching video.The research results show that:(1)No matter what kind of microvideos,subtitle presentation has great impact on the learning results of visual learners,and the learning results of“key words subtitle”are all best.(2)No matter what kind of micro-videos,subtitle presentation has less obvious impact on language learners.But from the mean value,the results of language learners of learning“full subtitle+key words subtitle”are rather good in the declarative knowledge videos;in the procedural knowledge micro-videos,the results of learning“key words subtitle”are rather good.(3)The influence of different subtitle presentation and learning styles on learners’cognitive load has no obvious differences.
