本研究目的在建立小學奈米科技的核心概念及概念圖。首先由文獻探討歸納出有關奈米科技的概念項目，發展「奈米科技核心概念」之問卷，並採用大慧 (Delphi) 調查法諮詢國內的專家學者共 28 位，其中包含大專院校之理工科系教授（11位）、科學教育學者（6位）及小學教師（11 位），透過三次來回的問卷諮詢後，建立出國小學生在不同學級應具有的「奈米科技」之核心概念，低年級有一項、中年級十五項、高年級三十三項，最後依歸納的核心概念建立奈米科技概念圖，以作為未來的國小課程指標之參考。

The purpose of this study was to establish the core concepts of nanotechnology and the concept map for the elementary school. Based on the literature review, we summarized the concepts related to the nanotechnology and developed the questionnaire of “The Core Concepts of Nanotechnology”. Then we conducted a Delphi survey to ask twenty eight experts to evaluate the importance of each concept. These experts include 11 professors from college of science and engineering, 6 professors from science education, and 11 elementary school teachers. Through three rounds of the survey, we conclude the core concepts of the nanotechnology correspondence to the different grades of the elementary school. Eventually, we concluded one concept of the nanotechnology should be taught in the elementary schools for lower-grade, fifteen concepts for mid-grade, and thirty-three concepts for higher-grade students. According to these results, we established the concept map of nanotechnology as the reference for future curriculum design for nanotechnology in the elementary school.
