变易理论由瑞典学者马飞龙教授于20世纪90年代提出,它源自马教授创立的“现象图式学”(phenomenography).变易理论认为,“学习必须透过审辨,而审辨必须透过变易”;“审辨能帮助我们更好地学习.”变易理论强调学习的意义在于能够审辨到学习内容中的变易.透过变易聚焦学习内容,基于学习内容中“变”与“不变”的不同组合,马教授得出了“对照(contrast)”、“区分(separation)”、“类合(generalization)”和“融合(fusion)”四种变易图式.变易理论对于指导高中数学教与学的意义何在呢?众所周知,数学作为一门基础自然学科,具有理论的抽象性、逻辑的严密性等特点.现实情况是,许多学
The theory of change is proposed by the Swedish scholar Professor Ma Feilong in the 1990s and originated from the “phenomenography” founded by Professor Ma.Changes in theory suggest that “learning must be resolved through scrutiny and judgment Must be through the change ”; “ Judgment can help us to learn better. ”Variation theory emphasizes the significance of learning lies in the ability to identify changes in the learning content.Focusing on learning content through variation, based on the learning content Different combinations of “change ” and “unchanged ”, Professor Ma came to “contrast”, “separation”, “generalization” and “ Fusion ”four variable schemata.What is the significance of variation theory in guiding high school mathematics teaching and learning? As we all know, mathematics as a basic natural subject has the characteristics of theoretical abstraction and logical rigor. The situation is that many learn
