本研究基於變動之觀念引用「開放建築」之理論以模擬操作最大宗之公共建築一學校教室單元，在開放且多元的教育理念下，期使教室單元能夠配合使用者使用需求的不同而去做改變，包括其空間形狀大小、空間隔間配置，都能輕易的做任何改變變動，且於變動更換的過程中，絕大部分組件皆可配合廠製或是再生利用的，以符合節能、低耗、經濟等之環境永續理念。
首先進行最多種樣式的班級教室空間單元使用型態收集，作為現行與未來教室型態變動所有可能性之依據。隨後遵行開放建築理論，進行相對不可變動之「支架體」擬定，而依據柱子位置與跨間數的不同而有(A)單跨間、(B)雙跨間、(C)三跨間等三種「支架體」其次於上述三種支架體環境限制下進行「填充體」層次之操作，即牆體與門窗等構件之變動實務模擬。每一「支架體」其下均有兩種以上之使用情境可能，並各自有其適用的構件規格。
本研究最終成果指出最為國內教室空間單元所通用的門、窗與實牆的尺度與規格;並對其組合方式提出相關規則與建議，俾利建築專業者設計的參考與教學師生的使用依據。

This research based on concept of change and applied Open Building theory to simulate operation in order to discuss the norm of media and interface in material of structure. The study object focused on the largest public building， the classroom space of elementary school for a unit. In addition， it drew up the proper space pattern for current education system. Furthermore， it expected the units could suit to users need to change. The flexible changes included the wall site and the setting of space that all could easily be changed and the entire replaced component could be recycled for use. All the designed were saving energy， low consumption and economy for sustainable environment concept.
First of all， this study investigated the maxima useful of classroom space unit for changing classroom space standard at current and future. Then， it applied the OpenBuilding theory to find the support of classroom. Basing on the difference of columns and spans there were three support types: (A) single span (B) dual span (C) triple span. Therefore， it worked on infill level and followed the setting of three support types to design by simulated the wall and components. Each support type could develop more than two situations of instruction for use. In addition， they had their own wall and components (doors， windows， partitions..)，
Finally， this study result indicated the most popular walls and components for the elemen-tary school's classroom space units in Taiwan. In addition， it also provided the norms and suggestions for construction. Hoping it would be useful for architects and educators.
