Abstract
本研究之目的在發展動畫輔助評量,來降低學生答題時非必要之外在認知負荷,此多餘認知負荷與評量目標無關,但可能導致學生解題錯誤,進而影響作答表現。本研究評量內容為國中自然科之地球科學天文月相單元,受試對象為105名九年級學生,其中49名分配到動畫輔助評量組,另外56名為圖文評量組。在評量信度方面,動畫輔助評量的信度為0.6,圖文評量信度為0.5。此外,本研究也試圖分析空間能力及作答成績間的關連性。
研究結果發現,動畫輔助評量組學生的表現顯著高於圖文評量組,且在解題過程有較低的認知負荷;另外,學生對於動畫輔助評量的接受程度亦較圖文評量高。除此之外,學生的空間能力與評量表現有某種程度相關,動畫輔助評量對高空間能力組的學生較低空間能力組有助益,但低空間能力組的學生則未達顯著。因此,在未來的研究上,動畫輔助評量的設計應更仔細考慮學生個體的空間能力差異。
In order to improve the validity of science testing design to evaluate students’ conceptual understanding of the relative motion of the Earth, sun, and moon, this study developed an Animation-Based Assessment (ABA) to ease secondary students’ extraneous cognitive load. A total of 105 ninth-grade students participated in this study. Forty-nine of the students were assigned to take the ABA, and the others were assigned to take the Graph-Based Assessment (GBA). The reliability estimates of the GBA and ABA are acceptable; the Cronbach’s alpha coefficients were .50 for GBA and .60 for ABA, respectively. The results of the analysis on students’ scores indicate that, in comparison with those of GBA, the students of ABA significantly got higher scores and reported lower cognitive load while solving test questions. Moreover, students’ acceptance towards the ABA was significantly higher than the GBA. Furthermore, it was found that the level of students’ spatial ability was associated with students’ test performance. The students with higher spatial ability significantly benefited from the ABA more than the GBA, but the students with lower spatial ability did not. Future research into animation-based testing design should carefully take the individual differences in spatial ability into account.
