和谐：小学数学教学设计的新视角——以“用字母表示数”的教学设计为例

Harmony:A New View of Primary Mathematics Teaching Designs——Take the Teaching Design of "Express Numbers with Letters" for Example

教学设计的主旨是以学习者为中心的学习环境设计，因而，教学设计过程中，多要素、多视角的和谐是必然的诉求。从小学数学学科的视角看，丰富的“和谐”内涵应包含这样的三方面含义：学校形态和原始形态的融通，实践经验和教育理论的结合，意义建构和文化传承的并举。

The nature of teaching design is to design learner-centered learning environment, which necessarily requires the harmony of the key elements and views in the process of teaching design. Seeing from the view of primary mathematics, the harmony enjoys a rich connotation, which includes the perfect harmony of school environment and original environment; connection of practical experience and educational theory; equally stressing to meaning construction and culture inherit.
