In language teaching methodology, "tissue rejection" refers to the unsuccessful implementation of a new teaching method or approach in a particular context. It's a metaphor drawn from medicine, where transplanted tissue might be rejected by the body's immune system. In this case, the "tissue" represents the new method, and the "body" represents the learning environment, including teachers, students, and their expectations.

Here are some key points about tissue rejection:

• Context matters: A method that works well in one setting might not work in another due to differences in learner expectations, teacher training, available resources, or educational culture.
• Gradual integration: Introducing new methods abruptly can lead to resistance. Effective implementation often involves gradual integration, considering existing practices and preparing learners and teachers for the change.
• Adaptation: Not all elements of a new method need to be implemented rigidly. Adapting it to the specific context can increase its chances of success.
• Understanding why: Analyzing why a method wasn't accepted can help teachers avoid similar pitfalls in the future.

Here are some common examples of tissue rejection in language teaching:

• Trying to implement a highly interactive method in a class accustomed to teacher-centered instruction.
• Introducing technology-based learning without proper training or infrastructure.
• Using materials or assessments not aligned with the local language proficiency framework or learner needs.

Remember, successful language teaching involves considering learners, teachers, and the context. It's important to choose methods that fit the specific environment and adapt them when necessary.
