摘要

本研究的目的為了解職前與在職中學生物教師對於遺傳學典範的了解情形，比較兩者的覺知情形差異，並進一步分析影響兩者區分古典與分子遺傳學典範的可能因素。本研究依據Kuhn對典範的概念將遺傳學分為古典遺傳學與分子遺傳學，進而以此為基礎，以半結構式晤談法來進行晤談。
本研究的結果顯示，在研究目的、研究對象、研究方法等方面，職前與在職教師的看法都相當一致，且其概念與文獻探討的內容相符。但關於基因的概念則是最容易發生迷思的地方，且通常發生在職前教師身上。如有兩位的職前教師對於分子遺傳學有著錯誤的基因成對概念，而這樣錯誤的概念則延續到基因型的概念上，使得這兩位職前教師對於基因型也出現錯誤的概念。有兩位職前教師認為分子遺傳學存在著基因決定論的概念。影響教師區分古典與分子遺傳學典範的可能因素為：學習經驗、研究經驗、備課經驗與教學經驗等。

The purpose of this study is to analysis the understanding of genetic paradigms of pre-service teachers and the in-service teachers, and also investigate the possible factors which influence teachers to distinguish the difference of classical and molecular genetics. Therefore, the study was based on semi--structured interview. The subjects are three in-service teachers and four pre-service teachers. The result of the study shows that the two groups are quite the same on the study objects and methods, but they have the misunderstanding about the concepts of gene, which are usually happens on the pre-service teachers. Because of the misunderstanding of gene pairs, two pre-service teachers had the misconceptions to the genotype. As the result, the possible factors which may affect the teachers to distinguish the paradigms between classical and molecular genetics are the learning experience ,study experience and most of all , preparation experience.
