Item Validation of a simulation-based assessment of inquiry abilities(2013-09-07) Wu, P. H.; Wu, H.-K.; Hsu, Y. S.; Hwang, F. K.Students’ fundamental abilities of inquiry are of value in science learning and have been increasingly emphasized as an important component of science education. Some assessments have been developed to measure students’ inquiry abilities, but few of them are simulation-based. To take advantage of the advanced technology, we developed a simulation-based assessment of inquiry abilities (SAIA) that allows students to generate scientific explanations and demonstrate their experimental abilities. This paper describes the validation of the assessment. Data were collected from 48 twelfth grade students at a local high school who were categorized into three groups based on their majored programs. Due to the different learning goals of the programs, students in the three groups were expected to have different levels of inquiry abilities and construct validity was estimated by using the known-groups method. Criterion validity was estimated based on the correlation between SAIA and a validated assessment tool, Classroom Test of Scientific Reasoning (CTSR). Content validity was investigated by examining the agreement among three experts. The results of the Kruskal-Wallis test and the post hoc analysis showed significant differences among three groups (χ2= 24.79, p < .01) so the construct validity of the assessment for distinguishing between the groups was supported. The content validity was confirmed by a satisfactory level of agreement between the experts with Kappa coefficients of .88 and .96. The criterion-related validity was ensured by a positive significant correlation between SAIA and CTSR (r = .40, p < .01). These results indicated that SAIA is a valid assessment to evaluate high school students’ inquiry abilities.Item The development of an evaluative instrument for teachers' practical technological pedagogical content knowledge(2012-12-15) Hsu, Y.

K.In the context of school settings, when implementing educational innovations such as technology-based assessments (TBAs) , teachers take a variety of factors into consideration including the resources provided by their school, the approval of parents, and students’ needs. To explore teachers' beliefs and relevant factors about TBAs, therefore, this study adopts the framework of the decomposed theory of planned behavior (DTPB) (Taylor & Todd, 1995), and aims at investigating the interaction between teachers’ beliefs and their actual use of TBAs. Forty technology-experienced science teachers participated in our semi-structured interview of assessment beliefs and practice. Responses from all teachers were coded and analyzed based on the coding scheme adapt from DTPB. Results showed the highlighted features of the most prevalent beliefs. On one hand, 75% of participating teachers perceived various kinds of usefulness of TBAs. On the other hand, teachers showed their concerns about the disapproval from schools and considerations of the external restrained conditions such as the lack of time, infrastructure and support personnel. By combining these features with teachers’ self-reported usage, we articulate the possible factors that may affect teachers’ usage. That is to say, teachers with more positive beliefs tend to use the TBAs frequently. Nevertheless, teachers would keep themselves away from use TBAs when they perceived many negative factors in Perceived Behavior Control beliefs and Subjective Norm beliefs.Item Designed features and actual affordances of a computer-based modeling tool(2011-09-09) Wu, P. H.; Wu, H.-K.; Hsu, Y. S.; Hwang, F. K.Item Development of senior high school students' modeling about air quality(2008-04-02) Lin, L. F.; Hsu, Y. S.; Wu, H.-K.; Hwang, F. K.The purpose of this study was to investigate how students develop modeling abilities after the scaffolded modeling curriculum and what characteristics of high performance students differ from those of low performance students in their modeling practices. The data included thirteen students’ (10 males and 3 females) pre and post modeling abilities test, and pre and post interviews. We designed and analyzed the interviews according to a coding scheme developed for an expert-novice study (Hsu et al., 2007). The results showed that students’ modeling abilities in designing a research to explore air quality have been improved, particularly in the reasoning process of anticipated conclusion and determine research variables of planning, and different performing students made a different improving pattern. The scaffolded modeling curriculums designed by the researchers shorten the gap between expert and novice in modeling air quality.Item Design distributed scaffolding for modeling a complex system(International Society of the Learning Sciences, 2009-06-13) Hsu, Y. S.; Wu, H.-K.; Hwang, F. K.; Lin, L. F.Based on the expert-novice analysis, we developed a distributed scaffolding curriculum for modeling air quality (DSCMAQ) to facilitate high school students’ modelbased reasoning in a technology-enhanced learning environment (APoME) which provided the Modeling Air Quality (MAQ) software associated with gradual complex learning tasks. Three studies had conducted to evaluate the effects of DSCMAQ on students’ modeling practices. In these three studies, students worked in a small group to complete DSCMAQ and their modeling abilities were improved after DSCMAQ.Item Modeling a complex system: Using novex analysis for developing an effective learning module(2007-04-18) Wu, H.-K.; Hsu, Y.
