This paper explores how the application of desirable difficulties—spacing, interleaving, retrieval, and generative learning—affects long‑term retention and productive performance among Iranian learners of German as a Foreign Language (GFL). Building on a cognitive framework that distinguishes the durability of stored knowledge from its momentary accessibility, the study adopted a mixed‑methods design with A1‑level learners from Tehran. A total of twenty participants (N = 20) were randomly assigned to an experimental group (n = 10) receiving instruction based on desirable difficulties and a control group (n = 10) following massed‑practice routines. Quantitative analysis showed that the experimental group had significantly higher retention and production skills scores in the delayed post-tests, and the results were statistically significant (p < 0.01). Qualitative data derived from semi‑structured interviews with six volunteer learners from the experimental group indicated that participants associated increased cognitive challenge with deeper understanding and enhanced motivation. The results show that including challenging but beneficial activities helps make language knowledge more lasting and easier to use in different situations. This offers support for the idea of using spaced retrieval and interleaved practice in teaching foreign languages in a structured way to help learners develop strong and long-term language skills.

This research discusses the pedagogical relevance of German idioms and Persian proverbs in language acquisition and intercultural communication. Idioms and proverbs are extremely useful in language competence and culture awareness development, but they are also very challenging for learners due to their non-literal nature and cultural boundness. This study uses a qualitative design to investigate how the use of idiomatic language in real communicative contexts improves comprehension, memorability, and intercultural competence in German language learners. Data were gathered based on semi-structured interviews with experienced teachers and advanced learners, and content analysis of idiomatic language selected from German and Persian texts. The findings show that the integration of cognitive and sociolinguistic approaches optimizes learners' ability to interpret idiomatic meaning and use them appropriately. Besides, computer-mediated resources and multimedia technology support memorization of idioms and their application in context. The instructional model in the research, by incorporating metaphorical comprehension with cultural contextualization, addresses knowledge gaps in traditional idiom instruction and emphasizes the necessity for contextualized learning environments. By enhancing both cultural sensitivity and language proficiency, this research has valuable pedagogical implications for language teachers and curriculum planners. Follow-up research should investigate the application of technology-assisted idiom learning in various linguistic and cultural contexts to validate the usefulness of the model suggested.
