本研究探討科學說明文內不同形式提示物（文字、插圖形式）對於國小學童記憶力與理解力之影響。研究對象包括72名國小六年級學生，研究設計採3（提示形式：無卅摘要卅插圖）×2（閱讀能力：高卅低）受試者間設計。並分別以不同變異數分析考驗各實驗處理間的參與者於自由回憶及閱讀理解兩方面表現之差異。研究結果為：（一）高閱讀能力組於兩測驗整體表現顯著優於低閱讀能力組（二）插圖提示對於學生的理解力有明顯提升，然記憶力則僅對於高閱讀能力者有助益。（三）對國小學童而言，摘要的提示效果對高閱讀能力者無明顯提升作用，然而，對低閱讀能力者卻可能有導致認知負荷加重的潛在危機。 The purpose of this study is to investigate the effects of graphic and textual signaling on elementary school students’ recall and comprehension of scientific text. The participants included 72 sixth grade students, and they were grouped into high- and low- ability subgroups, based on their performance on a reading comprehension test. The experiment was a 3 (signaling:, summary, and picture) × 2 (ability: high and low) between subject design. From the analysis of student’s recall and comprehension performance, we found out that (1) High ability students outperformed low ability students in both recall and comprehension tasks. (2) Graphic signaling could promote students’ comprehension for both groups of students, but only enhance high ability students’ memory. (3) The effect of textual signaling for high ability students was not significant; moreover, it might be a potential risk factor for an increase in the cognitive load of low ability students.
