A Development of the Test of Creativity Level for Earth Science Field

In the present study I developed the test for earth scientific creativity level and verified means to measure scientific creativity. I developed 22 test items and after being examined by science education specialist, 11 items were finally established, and these were applied to 104 middle students. Each answer paper was graded according to the standard answer that I developed and the results of analysis are as follows. First, to verify the validity of measuring means I figured out content validity. The content validity about test items and adequacy of evaluation goal was examined by 1 science education specialist and 3 middle school science teachers, 6 education graduate students. As a result of validity verification, the content validity was 82.7% and it showed that the test of earth scientific creativity was valid for evaluation goal and sub-factors of creativity. Second, to verify reliability of measuring means, I analyzed internal consistency of the test sheet of earth scientific creativity after finding correlation coefficient and Cronbach's $\alpha$. Cronbach's $\alpha$, the internal reliability coefficient, was 0.848. Therefore, it was verified that this test sheet of earth scientific creativity is reliable to measure the creativity of the middle school students. The correlation between sub-factors of creativity was statistically significant, and for the relation between the variables related to creativity, the originality was the most significant. This shows that in the procedure of scientific creativity and studying science, originality should be the most important factor.
