kielioppijärjestelmä

Kielioppijärjestelmä refers to the internal linguistic system that a language learner develops as they acquire a new language. It is not a direct replication of the target language's grammar, nor is it simply a translation of the learner's native language grammar. Instead, it is a dynamic and evolving mental construct that reflects the learner's current understanding and application of the rules and patterns of the language they are learning.

This system is characterized by a process of hypothesis testing. Learners observe linguistic input, form hypotheses about the grammatical structure and meaning, and then test these hypotheses through their own language production and by observing the feedback they receive. As they encounter more data and refine their hypotheses, their kielioppijärjestelmä becomes more complex and closer to the target language's grammar.

The development of a kielioppijärjestelmä can lead to phenomena such as overgeneralization, where a learned rule is applied too broadly to contexts where it doesn't apply (e.g., adding "-ed" to irregular past tense verbs in English). It can also manifest as undergeneralization, where a rule is applied too narrowly. The specific features of a learner's kielioppijärjestelmä are influenced by various factors, including the learner's first language, the learning environment, the teaching methods used, and the amount and type of exposure to the target language. Understanding the concept of kielioppijärjestelmä is crucial for educators and researchers aiming to support effective second language acquisition.
