Investigation of newly developed added damping and stiffness device with low yield strength steel

Energy dissipators, isolated-resistant and specific structural forms for earthquake resistance are popular topics in the research to improve shock-resistance. In this work, experimental methods were used to investigate the property of low yield strength steel. Carbon content in LYS material is lower than that in other steels; the ultimate stress is three times the yield stress. The ultimate elongation rate is about 62% and the ductility is 2–3 times that of A36 steel. In order to overcome some defects of ordinary use metallic dampers, the mechanical characteristic of low yield strength steel is used to develop added damping and stiffness for rhombic steel plate absorber. Test of the energy dissipation behavior for this newly developed device indicated that LYS could stably dissipate or absorb the input energy of earthquake. Then, the analytical model for the hysteretic behavior of this new device is proposed. Comparison of experimental data and numerical simulation results showed that this analytical model is suitable for simulating the hysteretic energy behavior of this new device.     

Why do people use information kiosks? A validation of the Unified Theory of Acceptance and Use of Technology

The importance of information kiosk development and implementation in the context of E-Government policies has been discussed in previous research. While many governments are today making considerable investments to implement information kiosks, previous research suggests that citizens may not use information kiosks in spite of their availability. However, the successful implementation of information kiosks depends significantly on whether or not citizens are willing to adopt the new information technology (IT). Therefore, based on the Unified Theory of Acceptance and Use of Technology (UTAUT), this study investigates the determinants of use behavior regarding information kiosks and the moderating effects of age and gender differences on the relationships between the determinants and behavioral intention/use behavior. Data collected from 244 respondents in Taiwan were tested against the research model using structural equation modeling techniques. The results partially support the applicability of the UTAUT in the context of information kiosks. The findings of this research provide several prominent implications for the research and practice of information kiosk development and implementation.

Computer-based collaborative problem-solving assessment in Taiwan

Abstract

The current study explores students’ collaboration and problem solving (CPS) abilities using a human-to-agent (H-A) computer-based collaborative problem solving assessment. Five CPS assessment units with 76 conversation-based items were constructed using the PISA 2015 CPS framework. In the experiment, 53,855 ninth and tenth graders in Taiwan were recruited, and a multidimensional item response analysis was used to develop CPS scales and represent the students’ collaboration and problem solving performance. The results show that the developed H-A approach is feasible for measuring students’ CPS skills, and the CPS scales are also shown to be reliable. In addition, the students’ CPS performance scores are further explored and discussed under the PISA CPS framework.

Modeling Randomness in Judging Rating Scales with a Random-Effects Rating Scale Model

This study presents the random-effects rating scale model (RE-RSM) which takes into account randomness in the thresholds over persons by treating them as random-effects and adding a random variable for each threshold in the rating scale model (RSM) ( Andrich, 1978 ). The RE-RSM turns out to be a special case of the multidimensional random coefficients multinomial logit model (MRCMLM) ( Adams, Wilson, & Wang, 1997 ) so that the estimation procedures for the MRCMLM can be directly applied. The results of the simulation indicated that when the data were generated from the RSM, using the RSM and the RE-RSM to fit the data made little difference: both resulting in accurate parameter recovery. When the data were generated from the RE-RSM, using the RE-RSM to fit the data resulted in unbiased estimates, whereas using the RSM resulted in biased estimates, large fit statistics for the thresholds, and inflated test reliability. An empirical example of 10 items with four-point rating scales was illustrated in which four models were compared: the RSM, the RE-RSM, the partial credit model ( Masters, 1982 ), and the constrained random-effects partial credit model. In this real data set, the need for a random-effects formulation becomes clear.     

How Well Performance in Curriculum-based Tests Predicts that in Life-based Tests: A Study of 12th-grade Students Learning Chinese Language

A sample of 209 secondary (12th grade) students were tested for their knowledge of Chinese characters, words, and idioms as specified in a Chinese Language syllabus. The students also took comprehension tests in the form of cloze tests based on passages selected from Chinese newspapers and literary works, covering occupations, social events, sports, leisure pursuits and international news. Although performance in curriculum-based tests was satisfactory, the students were found to have difficulty comprehending life-based reading materials. Probable causes for the lack of consistency between performances in the tests using different reading materials are discussed.     

University students’ perceptions of a holistic care course through cooperative learning: implications for instructors and researchers

The benefits of cooperative learning have been advocated in a wide range of educational contexts in higher education. There is, however, rare information on the contributions of holistic education courses on college students. Using grounded theory methods, this preliminary study was to explore participants’ perceptions of a holistic care course through cooperative learning. The results indicated that five primary categories including learning environment construction, multiple learning processes, cognitive change, solitary learning and transfer, and personal growth emerged as prominent and consistent themes. Moreover, positive and negative feelings about the learning experience, a greater understanding of holistic knowledge, and an enlargement of the experiences of connecting to others were also found. Finally, a pattern of university students’ construction of holistic knowledge was developed, and several research questions were generated. Future implications for research and practice on the holistic curriculum and cooperative learning in higher education were also suggested.
