  • The primary purpose of this study was to gather knowledge about $5^{th},\;6^{th},\;and\;7^{th}$ graders' proportional reasoning ability by investigating their reactions and use of strategies when encounting proportional or nonproportional problems, and then to raise issues concerning instructional methods related to proportion. A descriptive study through pencil-and-paper tests was conducted. The tests consisted of 12 questions, which included 8 proportional questions and 4 nonproportional questions. The following conclusions were drawn from the results obtained in this study. First, for a deeper understanding of the ratio, textbooks should treat numerical comparison problems and qualitative prediction and comparison problems together with missing-value problems. Second, when solving missing-value problems, students correctly answered direct-proportion questions but failed to correctly answer inverse-proportion questions. This result highlights the need for a more intensive curriculum to handle inverse-proportion. In particular, students need to experience inverse-relationships more often. Third, qualitative reasoning tends to be a more general norm than quantitative reasoning. Moreover, the former could be the cornerstone of proportional reasoning, and for this reason, qualitative reasoning should be emphasized before proportional reasoning. Forth, when dealing with nonproportional problems about 34% of students made proportional errors because they focused on numerical structure instead of comprehending the overall relationship. In order to overcome such errors, qualitative reasoning should be emphasized. Before solving proportional problems, students must be enriched by experiences that include dealing with direct and inverse proportion problems as well as nonproportional situational problems. This will result in the ability to accurately recognize a proportional situation.

  • The purpose of this study is to orient users' touchpoints in co-design experience, to identify their need via visualized experience map, to recommend valid design information in online e-customization services. A user-centered co-design experience map (UCEM) is adopted to analyze the relation between users' desire and time spent, so as to evaluate the online co-design experiences. Based on evolutionary algorithm and fuzzy theory, data of this study is collected from 30 participants. The data was analyzed by descriptive analysis in SPSS, and frequency query and word cloud in NVivo. Employing design category and evaluating users' time spent, the findings are that (a) vamp color matching is consistent with interview data; (b) supported by qualitative feedback, the virtual experience map played an important role in the co-design process and the visualized interaction process; and (c) participants prefer to get more information and professional help on color matching and exterior design. Based on the findings in design category, future work should be focused on developing a better understanding of design resource recommendations and multi-stakeholder communication.

  • This study gives opportunity for investigating how student teachers view the teaching profession and how they transfer their pedagogical knowledge into practice. The aim of the study is to investigate the teaching skills student teachers gained in the assessment of micro teaching of their peers. The participants are 30 mathematics student teachers enrolled in the teacher training program in a state university. Document analysis and semi-structured interviews are the research instruments and inferential & descriptive statistics are used for the data analysis. The findings suggest that the qualitative and quantitative peer assessments of student teachers were graded differently which results from the difference of perceptions about teaching and different conceptualizations of the teaching qualifications.

  • This study was to describe and understand the experiences of the physical disabled adult attending in public welfare program. The interview data were collected from seven persons and analyzed by using descriptive phenomenology of Colazzi. The procedural steps were that described the phenomenon of interest, collected participants' descriptions of the phenomenon, extracted the meaning of significant statements, organized the meanings into them clusters, wrote exhaustive descriptions and then incorporated data into an exhaustive description. The finding in 129 re-statements, 63 constructed meanings, 35 themes, 13 theme clusters, and six categories were deduced. The six categories were 'Life patterns exclusive health', 'Powerlessness by physical disabilities', 'Social supports', 'Positive motivation', 'Seeking to be holistic health', and 'Sense of accomplishment'. The study identified that social welfare program for the disabled necessities for health, learning, economy and their future in success. Therefore, we suggest there may be a need for supplying professional program for their health and welfare.

  • The purpose of this study is to develop clothing shopping orientation[CSO] scale reflecting the conceptual structure of CSO. For this purpose, a questionnaire composed of comprehensive 85 CSO items was developed through 2-step preliminary tests. Data was collected from two samples. One sample(n=559) was for scale development and the other sample(n=235) was for cross validity test. Descriptive analysis, correlation analysis, exploratory factor analysis, regression analysis, ANOVA, and confirmatory factor analysis were used for data analysis. For each lower-dimension within the CSO conceptual structure model, 1-2 items were selected based on the quantitative and the qualitative standards. As a result, a CSO scale composed of 31 items was developed, and reliability, construct validity, cross validity, convergent validity, discriminant validity, and criterion validity of the scale were verified. This study has significance in offering the standardized scale to both the academic and the practical fields.

  • Objective: The purpose of this study was to investigate relationships among child care teachers' role conflict, organizational commitment and teacher's sensitivity. It also aimed to test the mediating effect of organizational commitment on the pathway from child care teachers' role conflict on teacher's sensitivity. Methods: A self-report survey was conducted on 301 child care teachers in Chungbuk. Descriptive, means, standard deviations, correlations using SPSS 18.0, and Structural Equation Modeling using AMOS 18.0 were all conducted in order to analyze the collected data. Results: The results indicated that child care teachers' role conflict and organizational commitment had significant direct effects on teacher's sensitivity. This study also confirmed the significant mediating role of organizational commitment on the pathway from child care teachers' role conflict to sensitivity. Conclusion/Implications: The significance of role conflict and organizational commitment suggests that the integration of individuals with less conflict and more dedication will contribute more qualitative child care services by improving sensitive interactions with young children.
