Y; Yeh, T. K.; Barufaldi, J. P.This study explored the phenomenon of testing effect during science concept assessments, including the mechanism behind it and its impact upon a learner's conceptual understanding. The participants consisted of 208 high school students, in either the 11th or 12th grade. Three types of tests (traditional multiple‐choice test, correct concept test, and incorrect concept test) related to the greenhouse effect and global warming were developed to explore the mechanisms underlining the test effect. Interview data analyzed by means of the flow‐map method were used to examine the two‐week post‐test consequences of taking one of these three tests. The results indicated: (1) Traditional tests can affect participants' long‐term memory, both positively and negatively; in addition, when students ponder repeatedly and think harder about highly distracting choices during a test, they may gradually develop new conceptions; (2) Students develop more correct conceptions when more true descriptions are provided on the tests; on the other hand, students develop more misconceptions while completing tests in which more false descriptions of choices are provided. Finally, the results of this study revealed a noteworthy phenomenon that tests, if employed appropriately, may be also an effective instrument for assisting students' conceptual understanding.Item Assessing tenth-grade students' problem solving ability online in the area of earth sciences(Elsevier, 2007-07-01) Chang, C. Y.; Barufaldi, J. P.; Lin, M. C.; Chen, Y. C.This study examined tenth-grade students' (n=263) problem solving ability (PSA) online through assessing students' domain-specific knowledge (DSK) and reasoning skills (RS) in Earth sciences as well as their attitudes toward (AT) Earth sciences related topics in a secondary school of Taiwan. The students' PSA was evaluated based on a previous model (Chang, C. Y. (2004, November 26-27). Trends in assessing student earth science problem solving ability: the importance of domain-specific knowledge and reasoning skills in earth sciences. Paper presented at the Seoul Conference for International Earth Science Olympiad (IESO), Seoul, Korea; Chang, C. Y., & Barufaldi, J. P. (submitted). Does problem solving=prior knowledge+reasoning skills in science? An exploratory study. Journal of Experimental Education; Chang, C. Y., & Weng, Y. H. (2002). An exploratory study on students' problem-solving ability in earth science. International Journal of Science Education, 24(5), 441-452) which empirically established that students' PSA is a composite of DSK, RS and AT subscales. Major findings are as follows: (a) The correlation coefficient among students' DSK, RS and AT was relatively small, indicating that these subscales might have successfully represented different constructs of students' PSA; (b) a significantly positive correlation existed between students' PSA total scores and each subscale. It is, therefore, suggested that students' PSA may be potentially assessed online by measuring their essential components in the area of Earth sciences.
