摘要

本研究爲一跨年齡研究，研究者發展有關動物屬性、脊椎動物岐異性、動物分類概念的調查試題「中小學生動物及動物分類概念發展調查表」，作爲研究工具，利用本工具來探究國小六年級（156人）、國中二年級（146人）、高中二年級（166人）學生對脊椎動物屬性及動物分類概念的瞭解及發展情況。調查表回收分析後，找出作答中有明顯另有構念的個案（每一年級各8人）進行相關概念的晤談，綜合調查表的數據統計分析及晤談資料的分析，得到下列結果：1.受測學生的動物及動物分類概念知識的出現有順序性，例如：動物的特徵（屬性）出現的順序爲；能自由運動；異營性營養；無細胞壁；有中心粒。生活史上無世代交替這種屬性並未發展。2.受測學生的脊椎動物概念知識發展的順序爲：有脊椎骨（脊柱）；有鰓裂；有背側神經索；有頭顱。3.受測學生普遍具有對脊椎動物及動物分類概念知識的另有概念，如：珊瑚、海膽、海參不是動物；蛇、鰻魚、蝌蚪不是脊椎動物。

By using a cross-age research design, this study intends to explore student's conceptions in animal classification and vertebrate's animal classification at the 6th (N=156), 8th (N=146), and 11th (N =166) grades. The researcher developed a questionnaire with multiple-choice and free-response items to probe the students' understanding of attributes of animals, conceptions of animals, and conceptions of animal classification and vertebrates. A summary of the results is as follows: 1. The development of conceptual knowledge in the subjects about animal and animal classification shows a sequential order across ages. For example in conceptions of animal, there is an order going from ”movable”, to ”heterotrophic”, to ”no cell wall”, to ”centriole-own”. But the idea of ”no alternative of generation in life cycle” is still undeveloped. 2. The conceptual knowledge of vertebrates appears in the minds of the researched subjects in the sequence that follows: having vertebral column (back bone), gill-slit, dorsal nerve cord, and skull. 3. A wide range of alternative conceptions in conceptions of animal and vertebrate animal emerged. For example, corals, sea urchins, and sea cucumber are not considered animals; and snakes, ells and tadpoles are considered invertebrates.
