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.

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.
