I am conducting a study on the metaphorical ability of CFL learners.
The question types for studying learners' metaphorical comprehension ability are usually multiple-choice and judgment questions, but the multiple-choice and judgment questions will be blindly correct.
The question types of metaphorical output ability, paraphrase questions, sentence construction questions, and fill-in-the-blank questions are more scientific, but paraphrase questions and sentence construction questions need to control many variables, such as the learner's native language background and second language level must be the same.
Is there a more rigorous type or means of testing questions?
