摘要

本研究旨在探討在建模導向科學探究的教學策略下，高一學生的學習成效。學生在經過3週建模教學之後，再利用3週時間進行開放式問題的探究教學。學習成效的評估從學生對模型本質認識的變化、建模能力測驗的表現，以及探究的實作作品進行分析。結果顯示：一、學生在教學前後對於模型本質的認識有顯著差異。二、學生在建模能力測驗中對於模型選擇及模型建立歷程的表現較佳，對於模型效化及模型應用歷程則表現較差。三、分析學生作品發現，對於開放式探究，學生能夠掌握選擇正確變因，並且能透過實作找到變因之間的定性關係，但是距離科學社群能夠形成模型解釋實作成果仍有差距。值得注意的是，在建模能力測驗上，模型效化的結果顯示有雙峰現象，模型效化等級較高的學生在模型本質問卷的表現優於等級較低的學生，由此推測若要在模型效化達到較高等級，學生對於模型本質須要有較好的瞭解。臺灣在2019年實施「探究與實作」課程，本研究發現，高一學生受限於數學及建模能力尚未成熟，對於變因複雜的開放式問題探究，無法完成整體探究歷程。建議採用引導式的探究取代開放式探究，讓學生針對變因較單純之現象進行建模。同時建議應協助教師對於模型的認識與增能，以協助培育學生的建模與探究能力。

This study aims to investigate 10th grade school students' learning performance from using model-based inquiry instruction. After three weeks of modeling-based instruction, students were engaged in model-based inquiry with open-ended questions for another three weeks. Students' learning performance was analyzed via assessing changes of their (1) epistemological view of models, (2) performance in a modeling ability test, and (3) work collected from practice. Results show (1) a significant difference in students' epistemological view of models after instruction; (2) better performance on model selection and modeling construction processes; however, relatively poor performance in model validation and model application; (3) from their product of inquiry activities, students were found to select the correct variables and find the qualitative relationship among variables. There is still a gap that exists in the students' understanding before they form their models and explain the results of their actual work comparable to the way members of the scientific communities explain their results. A noteworthy finding is that a bimodal distribution exists in the model validation section on the modeling ability test. By comparing their responses on two questionnaires, the authors find that students who were ranked higher in their model validation performed better on questionnaire items related to the epistemological view of models. Therefore, investigators inferred from these results that students need a better epistemological view of models, in order to rank higher in model validation of the modeling competence.
