Reverse Teaching Design of Chemistry Based on UbD Theory——Taking"Iron and Its Compounds"Unit Teaching as an Example
UbD theory emphasizes reverse design as well as pre-evaluation.In addition,this theory that takes concepts as an anchor lays stress on giving priority to understand.So taking iron and its compounds as an unit teaching design based on the UbD theory,it can be added WHERE-TO elements and performance tasks,whose aim is to define learning priorities.Much more than this,the big ideas of this instructional design is dependent on the element view.The reason for making this professional teaching design is to construct the elemental compound analysis model from the classification view,transformation view and element view,and get the inspiration:the UbD theory focuses on the core big concepts of the discipline,leading to establishing the cognitive model;besides,it advocates multidimensional understanding and reaches at a higher-order thinking;another point cannot be ignored is that it makes teaching and learning activities and the evaluation a deeper integration,also,imple-menting the integration of"teaching,learning and evaluation".
