عن Open ENA

A small team. An open horizon.

Open ENA brings together learning science, quantitative ethnography, artificial intelligence, and educational technology.

We are building a transparent and approachable path into Epistemic Network Analysis—one where methods, interface decisions, and future capabilities can be inspected rather than hidden.

Why open

Openness is more than access.

It means making the path from evidence to interpretation visible: what the model receives, what the computation does, what the figure shows, and what it cannot claim.

الغاية والالتزام

Open ENA منصة غير تجارية مخصصة للأغراض التعليمية والبحثية، وستبقى مجانية إلى الأبد.

شكر وتقدير للمصادر العلمية

تستند Open ENA إلى النظريات والمناهج البحثية في Quantitative Ethnography (QE) وEpistemic Network Analysis (ENA). نتقدم بالشكر إلى University of Wisconsin–Madison، والأستاذ David Williamson Shaffer، والباحثين ومطوري البرمجيات والمتعاونين في Epistemic Analytics Lab التابع لـ Wisconsin Center for Education Research، تقديرًا لإسهاماتهم التأسيسية والمستمرة في QE وENA وأداة webENA.

الأسس النظرية لـ QE وENA

يجمع QE بين الفهم النوعي للأنشطة البشرية في سياقاتها وبين التحليل الكمي. (Shaffer, 2017)

يحلل ENA التزامن في ظهور العناصر المرمّزة ضمن سياقات ذات معنى لبناء شبكات من الروابط، ويتيح تمثيل هذه الشبكات بصريًا ومقارنتها إحصائيًا. (Shaffer et al., 2016)

تستند Open ENA إلى هذه الأبحاث لتنظيم البيانات المرمّزة وإعدادات النماذج ومقارنات الشبكات ضمن سير عمل بحثي في المتصفح. ويظل تفسير النتائج مرتبطًا بأسئلة البحث وأسس الترميز والمواد النوعية الأصلية. (Shaffer & Ruis, 2017)

أصل تصميم الواجهة: webENA

استخدم فريق Open ENA أداة webENA واتخذها مرجعًا عند تحديد المظهر والتخطيط الأوليين لواجهة هذه المنصة. ونقر بوضوح بأن هذا المرجع الأولي للواجهة يعود إلى فريق ENA الأصلي وعمله على تصميم webENA في ماديسون بولاية ويسكونسن في الولايات المتحدة (Madison, Wisconsin, USA).

يسترشد التمثيل البصري لشبكات ENA أيضًا بالأبحاث المتعلقة بالتصميم البصري والتفسير. (Tan et al., 2022)

Open ENA منصة مستقلة يتولى فريق Open ENA صيانتها.
