摘　　要：知识建构教学的核心是观点的持续改进,目前的研究尚处于轨迹追踪等表层行为分析,缺乏观点改进多行为之间的关系以及知识进化内在机理的探讨。研究通过跟踪某大学教育技术学专业56名本科学生一学期的课程“影视动漫赏析”,运用滞后序列与内容分析法对学生发表在知识论坛平台上的623条观点进行分析。研究结果表明:观点改进行为显示出“萌生与聚集→选择与种群生成→激荡中的持续生长→跃迁与延续”的阶段性发展规律;观点显著行为序对很好地映射在了多轮波普尔循环的知识进化中,足够的分裂与变异、不断的融合和自我生长行为对知识进化起着关键作用。一些未预见发现充分体现了知识建构基于原则的灵活性特征。The core of knowledge building is the continuous improvement of ideas.The current research mainly focuses on the analysis of superficial behaviors such as trajectory tracking,but lacks the exploration of the relationship between multiple behaviors of idea improvement and the internal mechanism of knowledge evolution.Through tracking the course"Appreciation of Film and Animation"of 56 undergraduate students majoring in educational technology in a certain university,this study analyzes 623 ideas posted by students on the knowledge forum platform by using lag sequence analysis and content analysis method.The results indicate that the behavior of idea improvement shows a developmental pattern of"emergence and aggregation,selection and population generation,continuous growth in agitation,leap and continuation".The significant behavior sequences are well mapped onto several rounds of Popper's cycle of knowledge evolution,with sufficient splitting and mutation,continuous fusion and self-growth behavior playing a key role in knowledge evolution.The principle-based flexibility of knowledge construction is well characterized by some unforeseen findings.
