非正式教育成為人們主要學習管道，許多資訊科學教學網站提供運算思維的學習資源。本研究探討臺灣瀏覽量排名前三的資訊科學網站，了解教學內容的知識分類及STEM相關部分。研究使用3個資訊科學教學網站共795篇文章，進行內容分析。研究發現：（一）資訊科學網站重視技術性知識，強調實用性和實際操作方法；（二）網站教學偏重技術性知識，較少涉及原理性知識，對於學習進階知識幫助有限；（三）網站教材對應用於資訊科學的數學相關陳述，普遍不足；（四）3個網站STEM教學文章風格一致，但著重傳遞的知識種類，有所不同。T客邦和重灌狂人偏技術性知識，iThome著重新事件、趨勢和解決方案的事實性知識。研究建議，網站管理者應注意教學文章內容，在傳遞知識時需有敘事主軸，使其具有市場區隔性。若能理解知識類型的相互搭配以及STEM科際整合之意涵，或許能幫助優化教學文章內容。

Currently, informal education has emerged as an effective channel for learning, with numerous computer science teaching websites providing resources to foster computational thinking. This study conducted a content analysis of Taiwan’s three most frequented computer science websites to understand the knowledge categories and STEM integration. Key findings from the 795 articles of these websites are: (1) These websites focus on technical skills, practical application, and experiential learning methods. (2) Although these websites have excellent performance in terms of imparting technical knowledge, they often neglect the underlying principles or “know-why,” which limits their utility in providing a comprehensive understanding to users. (3) A notable deficiency exists in mathematics-related material, which has crucial applications in computer science. (4) While STEM-focused articles are thematically aligned, the types of knowledge they convey varies substantially. TechBridge and Briian websites focus on technical knowledge, whereas iThome provides new events, trends, and practical solutions.This study suggests that website administrators should prioritize thematic consistency and narrative coherence in their educational content to ensure distinct market segmentation. A deeper comprehension of the interplay between different types of knowledge and the meaning of interdisciplinary integration in STEM can enhance the effectiveness of these educational online articles.
