The purpose of this study is to develop a valid and reliable examination on the measurement of the epistemological belief in the knowing and knowledge of Korean university students. Regarding the above, we initially selected 63 items through the review of literature on epistemological belief and then, based on content validity, 56 items were used for the primary test. With the result from the primary test tested on 168 Korean university students, we progressed onto the main test with only 44 items. The main test was conducted on 437(Male: 184, female: 253) Korean university students. Through the main test, we found 7 different kinds of factors and selected 34 items. The 7 factors are composed by certainty of knowledge, simplicity of knowledge, source of knowing, justification of knowing, innate ability, quick learning, and regulatory learning. After selecting the final items, we proceeded with the multivariate generalizability for investigation as to whether it is the more reliable examination. After investigating the source of error through the G study adjusted ρ? × i°(ρ × (i:υ)) design, we proceeded with the D-study for finding the generalizability coefficients and phi coefficient. With the result from the G-study, the ρ × i,e effect are bigger than others. Besides, as a result of the D-study, we can confirm the reliability coefficient from the .67 to .85 of G-coefficient and .64 to .83 of phi-coefficient. This study has meant to synthesize diverse factor structure and secure a higher reliability than the past study. Thus, this measurement tool will be useful for judging the effectiveness that various alternative teaching methods makes the epistemological belief change and development more sophisticated.
