教學結構圖系列化之推估與應用

On Estimation of Strategic Task Sequencing Method to Four Kinds of Teaching Types in Knowledge Structures

根據教學結構圖系列化之理論，教學策略可分成脈絡型、基礎型、應用型與非脈絡型四種型態，本研究旨在利用隸屬度函數，提出此系列化理論之推估理論，來估計一個給定之教學順序，其所歸屬之型態。本研究另根據分數加法之實務教學，經調查彰化縣10所國小之教學活動設計，根據被80%教師偏好之教學順序，進行詳細之推估計算，結果顯示被多數教師所偏好之教學，屬於應用型之教學策略。

According to strategic task sequencing theory, there are four kinds of teaching types which are contextual, fundamental, applicable and non-contextual types, respectively. The primary objective of this study is to propose an estimation method via the membership function in order to determine the teaching type, provided a teaching sequence is given.In addition, we apply the proposed estimation method to the teaching of fraction addition in elementary school at Changhua county. Ten of teaching activity designs for this teaching was collected. We obtain a teaching sequence in which 80% teachers have designed it. In terms of the proposed estimation theory, we calculate the process of the estimation in detail. As a result, the applicable type of teaching sequence was found for this estimation.
