    Online assessing tenth-grade students' problem solving ability in the area of Earth Sciences
    (2005-06-27) Chang, C. Y.; Barufaldi, J. P.; Lin, M. C.; Chen, Y. C.; Jhan, J. Y.
    This study examined tenth-grade students' (n = 263) problem solving ability (PSA) online by tapping students' domain-specific knowledge (DSK), reasoning skills (RS), and attitudes toward (AT) the subject with respect to debris-flow-hazard related topics in a secondary school of Taiwan. The students' PSA was evaluated based on a previous model (Chang, 2004) which empirically established that students' PSA is a composite of DSK, RS and AT subscales. Major findings are as follows: (a) The correlation coefficients among students' DSK, RS and AT were 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.

    Evaluating students' problem solving ability on the earthquake related topics through Web-based testing
    (2005-06-27) Lin, M. C.; Chang, C. Y.; Barufaldi, J. P.; Chen, Y. C.; Jhan, J. Y.
    Tenth-grade students' (n = 75) problem-solving ability was evaluated through a Web-based test in a secondary school of Taiwan. This research was based on a previous empirical model (Chang, 2004), which proposes to assess three essential components, i.e. domain knowledge, reasoning skills, and test attitudes to map students' problem-solving ability. The results indicated that significantly positive correlations existed between students' problem-solving ability and the aforementioned components. Quantitative data analysis also suggested that the correlation coefficients among the above components were not high, signifying that these components might have effectively characterized different mechanism of students' problem-solving ability. Implications as a result of the study for the future design of web-based testing were further discussed.

    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).
