Creative metacognitive strategy knowledge is a key factor in managing uncertainty, solving complex problems, and fostering creative thinking. Based on relevant theories and qualitative interviews from both domestic and international sources, our study developed a structural framework for creative metacognitive strategy knowledge and designed an assessment scale tailored for undergradur ates. Through analy Zing the data from 2,530 undergraduates, a formal scale was ultimately developed, which includes two subscales

for knowledge types and application of creative metacognitive strategies, with a total of 36 items. Through exploratory factor analysis, confirmatory factor analysis, and rigorous tests of reliability and validity, the scale demonstrated strong item discrimination, internal consistency, stability, structural validity, and criterion-related validity. These findings indicate that the scale is a reliable and effective tool for assessing creative metacognitive strategy knowledge in university students.
