Learning-Behavioral Affordances in German Textbooks: Sustainability-Oriented Intercultural Competence Development in China

This study examines how German textbooks provide learning-behavioral affordances for sustainability-oriented intercultural competence development. Drawing on Klieme’s competence-model logic, ESD, intercultural competence research, learning behavior theory, and affordance theory, it treats “sustainable intercultural competence” not as a standardized construct but as a working shorthand for the sustainability-oriented development of intercultural competence. Methodologically, the study adopts a directed qualitative content analysis supplemented by descriptive frequency aggregation. All 37 units across the four volumes of Meilenstein were coded on a 0–2 scale across three affordance dimensions: cognitive-understanding affordance, reflective value-judgment affordance, and interaction-action affordance. The findings show that the series provides substantial but uneven affordances. Interaction-action received the highest aggregated score, followed by cognitive-understanding, whereas reflective value-judgment remained substantially lower. Units on family, identity, sustainability, and civic engagement offer the most balanced affordance structures, whereas everyday practical units privilege communicative action and disciplinary units privilege cognitive understanding. The study argues that textbook-based intercultural learning should be examined not only through topic inclusion but also through how texts, prompts, and tasks organize opportunities for comparison, reflection, judgment, negotiation, and action.
