数学课件设计中降低认知负荷的有效策略──以初中数学PPT课件设计为例

On Effective Strategies to Reduce Cognitive Load on Mathematics Courseware Design:Taking the Design on Middle School Mathematics as an Example

课件作为对师生的教与学产生重大影响的重要载体,不适当的设计将不同程度地导致学生认知负荷的增加。从课件设计视角研究降低认知负荷问题是一个具有现实意义的重要课题。结合课件设计实际与教学经验,提出初中数学课件设计应从通过数学样例技术、导航归类技术、简单合理的组织方式、学习者设计技术4个方面来降低认知负荷。

Courseware as an important vector which has a significant impact on learning and teaching of students and teachers,improper design will cause cognitive load in varying degrees.So a perspective of courseware design to reduce the cognitive load is an important and topical issues.Combined the practical design and teaching experiences,middle school mathematics courseware design should be made through the mathematics sample techniques,the navigation classification technology,the simple and rational organization,and the learners＇ design techniques to reduce the cognitive load.
