中等學校生物教師教學能力之研究 作者:鄭湧涇(國立臺灣師範大學生物學系)

摘要：

本研究以「生物教學能力測驗」（BTCI）為研究工具，探索職前及在職生物教師之生物教學能力素養。BTCI與所含兩分測驗的內部均質性信度分別為0.81,0.80,和0.64，略低於BTCI發展與效化時的信度值。
研究的結果顯示，職前生物教師的生物教學能力顯著優於在職之生物老師（p<0.01）。主修生物之在職生物教師，其BTCI整體測驗的分數顯著高於 非主修生物之在職生物教師（P<0.05）；這種情形，在兩個分測驗的得分方面亦然。這個結果顯示，主修生物的教師，生物教學能力素養顯著優於非主 修生物的教師。變藝術分析的結果顯示，職前生物教師、主修生物的在職教師和非主修生物的在職教師三群樣本，生物教學能力素養有顯著差異，職前生物教師之生 物教學能力顯著優於主修生物與非主修生物之在職教師。
此外，研究的結果亦顯示，生物教學能力與生物探討技能和對科學的本質的了解兩項教師特性之間，分別有中度至低度相關存在，及生物教學能力較佳的教師，其生物探討既能和對科學的本質的了解亦較佳。此外，生物教學能力與生物認知偏好的Q（批判質疑）形式之間亦有顯著的正相關，而與R（記憶）型式之間則有顯著之 副相關存在。

關鍵詞：生物教學能力、生物教師、生物探討技能、對科學的本質的了解、生物認知偏好

A Study on Teaching Competency of Secondary School Biology Teachers Author: Yeong-Jing Cheng(Department of Biology, National Taiwan Normal University)

Abstract：

In this study, the Biology Teaching Competency Inventory (BTCI) is used to investi-gate the biology teaching competencies of pre- and in-service biology teachers. The in-ternal-consistency reliabilities of the BTCI and two subtests are 0.81, 0.80, and 0.64, re-spectively. The values are slightly lower than those reported in the development and val-idation study.
Data analysis reveals that preservice biology teachers score significantly higher on BTCI than inservice biology teachers (p<0.01). Biology teachers who were biology ma-jor during their undergraduate study score significantly higher on BTCI than nonbiology majors (p<0.05). These findings are also true for the two BTCI subtests. These results indicate that the biology teaching competencies of biology-major teachers are better than those of non-biology-majors. Oneway ANOVA shows that there are significant dif-ferences of the BTCI scores among three groups of subjects, namely, preservice teachers, biology-major and non-biology-major teachers. The biology teaching compe-tencies of preservice biology teachers are better than those of biology- and non-biology-major biology teachers.
The results of the study further indicate that moderate to low correlations exist be-tween biology teaching competency and biology inquiry skills and understanding of the nature of science, respectively. That is, subjects who possess better biology teaching competencies also show better biology inquiry skills and better understanding of the na-ture of science. In addition, the BTCI scores correlate positively with Q preference mode scores, and negatively with R preference mode scores in a biology cognitive pref-erence assessment.
