An investigation of Taiwan University students' perceptions of online academic help seeking, and their web-based learning self-efficacy

This study was conducted to investigate Taiwan University students' perceptions (including experience, confidence and preference) of online academic help seeking (OAHS) and students' level of web-based learning self-efficacy (WLSE). Two instruments, OAHS questionnaire, consisting of information searching, formal and informal query scales, and WLSE questionnaire, including general and functional scales, were then validated through collecting the responses from 300 university students. Results indicate reciprocal relations between experience, confidence and preference in students' online academic help seeking behaviors. Students' academic help seeking behaviors were related to their general self-efficacy in a web-based course setting. Students' functional WLSE was related to their perceptions of information searching for OAHS. Findings of this study also imply that students' experience of seeking help from informal online channels is prominent when they participate in a web-based course.     

THE DEVELOPMENT OF A COMPETENCE SCALE FOR LEARNING SCIENCE: INQUIRY AND COMMUNICATION

The objective of this study was to develop an instrument to measure school students’ competence in learning science as part of a large research project in Taiwan. The instrument consisted of 29 self-report, Likert-type items divided into 2 scales: Competence in Scientific Inquiry and Competence in Communication. The Competence in Scientific Inquiry scale contained 4 subscales: presenting questions and hypothesis, planning, experimenting and data gathering, and data analyzing, interpreting, and concluding. The Competence in Communication scale contained 4 subscales: expressing, evaluating, responding, and negotiating. Students were recruited randomly from primary, junior, and senior high schools in different regions of Taiwan to validate the instrument and establish its reliability and validity. The results of the analyses indicate that the instrument, scales, and subscales have reasonable internal consistency; that the theoretical structure was supported by empirical data; and that the subscales are homogeneous. These results indicate that it is an appropriate tool for measuring students’ competence in learning science. Implications and suggestions for further studies are included.

本文证明了PVDF与at-PMMA共混物中两者之间非常弱的相互作用 .随着PVDF质量分数的提高 ,共混物显示出更为异相的性质 .通过红外光谱的示差扫描技术 ,减去共混物谱图中PVDF和at-PMMA的谱图 ,显示在高PVDF含量时 ,υc=o吸收峰向低波数移动 ,表明它们之间的相互作用存在于PMMA的羰基和PVDF的H原子之间 .接触角测量表明随着PVDF含量的提高 ,膜的憎水性增强 .当PVDF的含量超过 30 % (质量 % )时 ,对水的接触角大于 90° ,显示了优异的憎水性 .但是 ,膜可以被正己烷完全润湿 ,因而对正己烷的接触角测量不到     

Adaptive synchronization of chaotic Colpitts circuits against parameter mismatches and channel distortions

In this work, synchronization of chaotic Colpitts circuits, using adaptive controllers to combat circuit parameter mismatches and channel distortions, is studied by numerical simulations. Synchronization errors caused by different main circuit components are compared, and compensation for time-constant and time-varying circuit parameter mismatches is demonstrated. Different kinds of channel distortions, including time-constant and time-varying channel attenuation, Additive White Gaussian Noise (AWGN) are all investigated by numerical simulations and discussed. Simulation results indicated that the synchronization performance of chaotic Colpitts circuits can be greatly improved by applying adaptive controllers when parameter mismatches and channel attenuation are considered as time-constant or time-varying, but have no obvious enhancements regarding the effect on AWGN channel.
