摘要

本研究以光合作用單元文本為標的，旨在探討現行文本釐清學生迷思概念的效果；並在科學內容一致的情況下，探究依據漢語特性與科學語言所修改的文本是否能提昇釐清學生迷思概念的效果及促進新概念的學習。依據上述目的研究分成兩部份，第一部份隨機將三個現行文本分派給288位六年級學生閱讀，以學生閱讀前、後迷思概念改變情形評估現行文本的可讀性；第二部份亦隨機將三個現行版及三個對應的修改版分派給711位學生閱讀，利用學生閱讀理解測驗結果檢驗改寫的效果。研究發現現行文本分類/組成關係的論述內隱且不明確，造成學生某些迷思概念加深；而依據漢語及科學語言特性所改寫的文本較能協助讀者釐清迷思概念，且俾益其習得新的科學概念。

This study aimed to explore the effects of different photosynthesis texts on students' reading comprehension. Three texts of 'photosynthesis' of current junior high science textbooks were excerpted as target texts (H-, K-, & N-text); these were the re-edited as DH, DK, & DN-text according to the 'language of science', which is inspired in the light of systemic functional linguistics and features of Mandarin, such as the implicit taxonomic implications of nominal groups, zero anaphora, and part-kind discourses. These six texts deployed almost the same content words related to photosynthesis and were controlled to have the same layout and almost the same number of words and clauses. This research was composed of two stages. The effects on readers' conceptual change induced by reading current texts were explored firstly. Total 288 sixth graders were randomly assigned to reading H, K & N-text. The effects of current and re-edited texts were then compared. Total 711 sixth graders participated in this stage and were randomly assigned to read these six texts. Major findings indicated that (1) current texts did help the readers in understanding some concepts, unfortunately, they also worsened the level of understanding in other concepts, especially the concepts related to ambiguous part-of and kind-of relations deployed by the current texts. (2) The re-edited texts were more helpful to clarify readers' misconceptions and to learn new concepts. These results implied that readers could be benefited from the texts that constructed according to the features of Mandarin together with the 'language of science'.
