    Supporting scientific modeling practices in atmospheric sciences: Intended and actual affordances of a computer-based modeling tool
    (Routledge, 2013-06-27) Wu, P. H.; Wu, H.-K.; Kuo, C. Y.; Hsu, Y. S.
    Computer-based learning tools include design features to enhance learning but learners may not always perceive the existence of these features and use them in desirable ways. There might be a gap between what the tool features are designed to offer (intended affordance) and what they are actually used (actual affordance). This study thus aims at investigating how the design features of a computer-based tool supported high school students' modeling practices in atmospheric sciences. Twenty-three 10th graders participated in 16 hours of learning activities by using the tool. We conducted a detailed analysis of students' computer activities, their use of the design features, and their building, testing, analyzing, and evaluating practices. The analysis showed that while some design features such as Variable List and Testing Variables were perceived by students and successfully afforded their enactment of building and analyzing practices, other features including Screen Shot and Edit were rarely used or not utilized in the desirable ways. Based on the findings, this study suggests that the realization of intended affordances may involve factors of learners' characteristics, the nature of learning activities, and the complexity of tasks, and constructs an affordance analysis scheme to inform the design of computer-based learning tools.

    Toward an integrated model for designing assessment systems: An analysis of the current status of computer-based assessments in science
    (ELSEVIER, 2013-10-01) Kuo, C. Y.; Wu, H.-K.
    Drawing upon an integrated model proposed by Bennett and Bejar (1998), this review study examined how 66 computer-based science assessments (CBSAs) in basic science and medicine took advantage of advanced technologies. The model regarded a CBSA as an integrated system, included several assessment components (e.g., assessment purpose, measured construct, test and task design, examinee interface, and scoring procedure), and emphasized the interplay among these components. Accordingly, this study systematically analyzed the item presentations of interactive multimedia, the constructs measured, the response formats in formative and summative assessments, the scoring procedures, the adaptive test activities administrated based on the algorithms related to the item response theory (IRT) and other rules beyond IRT, and the strategies for the automatic provision of informative hints and feedbacks in the CBSAs. Our analysis revealed that although only 19 out of 66 assessments took advantage of dynamic and interactive media for item presentations, CBSAs with these media could measure integrated understanding of science phenomena and complex problem-solving skills. However, we also found that limitations in automated scoring may lead to infrequent use of the automated provision of hints and feedbacks with open-ended and extended responses. These findings suggest the interrelatedness of the assessment components, and thus we argue that designers should repeatedly consider the relationships between components of CBSAs to ensure the validity of the assessments. Finally, we also indicate the issues for future research in computer-based assessments.
