Об 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.

Образование, исследования и бесплатный доступ навсегда

Open ENA — некоммерческая платформа для образовательных и исследовательских целей, которая навсегда останется бесплатной.

Признание вклада основателей

Open ENA опирается на теорию и методы Quantitative Ethnography (QE) и Epistemic Network Analysis (ENA). Мы выражаем благодарность University of Wisconsin–Madison, профессору David Williamson Shaffer, а также исследователям, разработчикам и коллегам из Epistemic Analytics Lab в Wisconsin Center for Education Research за основополагающий вклад и продолжающуюся работу над QE, ENA и webENA.

Теоретические основы: QE и ENA

Quantitative Ethnography (QE) объединяет качественное понимание человеческой деятельности в её контексте с количественным анализом. (Shaffer, 2017)

Epistemic Network Analysis (ENA) моделирует связи между закодированными элементами, которые встречаются совместно в содержательно значимых контекстах. Эти связи образуют сети, структуры которых можно визуализировать и сравнивать статистически. (Shaffer et al., 2016)

Опираясь на эти работы, Open ENA объединяет закодированные данные, настройки моделей и сравнение сетей в рабочем процессе, доступном в браузере. Исследователям необходимо интерпретировать результаты с учётом исследовательского вопроса, оснований кодирования и исходного качественного материала. (Shaffer & Ruis, 2017)

Происхождение дизайна и связь с webENA

Команда Open ENA использовала webENA и опиралась на него как на образец при создании первоначального внешнего вида и компоновки этой платформы. Мы прямо признаём, что этот источник дизайна восходит к первоначальной команде ENA и её работе над webENA в Мэдисоне, штат Висконсин, США.

Визуализация сетей ENA также опирается на исследования визуального дизайна и интерпретации. (Tan et al., 2022)

Open ENA — независимая платформа, которую поддерживает команда Open ENA.
