    The positive and negative effects of science concept tests on student conceptual understanding
    (Taylor & Francis (Routledge), 2010-01-01) Chang, C. 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.

    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.

    地球科學教室學習環境問卷之研發與初探
    (花蓮市：中華民國科學教育學會, 2004-12-01) 李旻憲; 張俊彥
    本研究旨在研發「地球科學教室學習環境問卷」(Earth Science Classroom Learning Environment Instrument, ESCLEI)，並藉此問卷初步調查高一地球科學教室學習環境的特質，進而初探其在地球科學學習與教學上的可能意涵。ESCLEI包含「學生中心」與「教師中心」兩分量表，同時亦將「理想版」問卷及「實際經歷版」問卷同置於一份問卷中。試驗性研究對象來自台北市及台中市共兩所公立高中，計有四位地科老師分別執教的四個班級之高一學生參與，有效樣本共167人。研究設計採問卷調查法，主要目的爲藉由本次試驗性研究，進行初步結果分析及問卷細緻化的工作，以利後續之大規模施測。研究結果顯示：一、ESCLEI已具有一定之信度與效度；二、學生心目中似乎可同時接受教師中心與學生中心的學習環境，這可能意味著國內學生對（地球）科學教室學習環境的看法，可能有其別於國外的獨特性；三、在教師中心及學生中心的分量上，學生實際經歷的學習環境均較心目中理想的學習環境有顯著的落差；四、學生理想中的學習環境在教師中心與學生中心的分量上並無顯著差異；五、學生實際經歷的學習環境中，教師中心的分量顯著地高於學生中心的分量，顯示國內長久以來地球科學教室的學習環境，在高中階段仍是以教師爲中心的；六、本問卷似可區別出不同地球科學教師所營造出的教室學習環境。以上的研究結果對於地球科學的教學和學習應具有一定的啟示並對後續更深入之研究工作有相當的助益。

    A problem-solving based computer-assisted tutorial for the earth sciences
    (Wiley, 2001-09-01) Chang, C. Y.
    This study investigated the effects of a Problem-Solving based Computer-Assisted Tutorial (PSCAT) on earth science achievement and attitudes toward earth science of tenth graders (16-year olds) in a senior high school in Taiwan. A total of 137 students who were enrolled in four earth science classes participated in this pre-test/post-test control-group experiment. The experimental groups received the PSCAT; whereas the comparison groups received a Lecture-Internet-Discussion (LID) teaching approach. A multivariate analysis of covariance on the post-test scores of the Earth Science Achievement Test and Attitudes Toward Earth Science Inventory, with students' pre-test scores as the covariates, suggested that PSCAT produced (almost) significantly greater gains on students' earth science achievement than did the LID approach and that no statistically significant increase or decrease in student attitudes toward earth science was found for either group.
