國小學童資訊素養檔案評量之發展研究

Developing Portfolio toAssess the Information Literacy of Elementary Students

「學習如何學」是二十一世紀教育最重要的目標，而能夠有效地運用資料則是能夠終身學習的必備能力。本研究的目的在發展國小學童運用資訊能力的檔案評量系統並透過試作初步檢驗其效度。此評量系統的架構建立於資訊素養教學的歷程模式上。系統發展含結合各學習領域的實作作業設計、作業的評量規準、檔案結構、以及檔案系統的信效度研究。其特色為以大六教學法為理論架構，實作作業融入各學習領域以及考慮教學現場情境。目標在整合課程、教學與評量達到以基本能力為核心的課程架構的要求。透過資訊素養教育文獻的探討、教師訪談以及國語、社會、和自然與生活科技領域的課程內容分析，研究者呈現如何進行檔案內容規劃、檔案作業類型分類、設計檔案實作作業以及評分表。檔案效度的探究上，著重Messick（1995）所主張建構效度中的幅合/區辨效度、後果效度以及實質面。效度研究結果顯示檔案對學生資訊素養的提升以及教師教學有正面的影響。檔案幅合效度可接受，但區辨效度並不理想。學生在解決作業的資訊問題時，必須用到大六歷程。

“Learning to learn” is the most important goal of education for 21st century， and the information literacy and skills are key competences for lifelong learners. The purpose of the study was to design a valid portfolio system of information literacy. The portfolio system adopts Big Six Skills as its theoretical framework， with the following components: information tasks in subject areas， scoring procedures for each of the tasks， the structure of the portfolio， and the psychometric characteristics of the portfolio system， including evidence on reliability and validity. Model-based framework， integrated information tasks， and specificity of instructional context are the features of the portfolio system. With information obtained from the literacy literature review， teacher interview， and curriculum analyses， the researcher designed and developed the content of the portfolio， the information tasks， and the rubrics of the information task. Three types of evidence， convergent and discriminant validity， consequential validity， and substantive validity emphasized by Messick (1995) were used as validity criteria for the portfolio. Results showed that the portfolio was strong in convergent validity but weak in discriminant validity. The portfolio system enhanced students’information literacy and influenced literacy instruction positively. In addition， when performing information assessment tasks in subject projects， students did utilize the Big Six Skills.
