I. Introduction
Problem-based learning (PBL) is a commonly used and effective instructional approach. Teachers typically design questions and tasks to facilitate instruction and evaluate students' understanding of the material. Reading comprehension is consistently incorporated into PBL as a common task in language education [1]. This task involves various question types and difficulty levels to evaluate learners' comprehension and information-processing skills. However, due to the complexity of question design and assessment development, teachers frequently depend on preprepared learning materials for instruction. This includes using standardized questions for the entire class during reading comprehension activities. Although this approach facilitates learning assessment, it has a limited impact on developing diverse levels of reading comprehension skills.
