This study explores undergraduate course instructors’ stated beliefs and practices toward student-centered learning. In-depth interviews with four undergraduate course instructors in a variety of disciplines in the United States revealed their beliefs about the roles of instructors’ and students’ as well as student-centered learning. Also, the instructors’ teaching styles are measured and compared with their stated beliefs and practices. Through thematic analysis and deductive and inductive...

This study aims to examine how context-specific measures of students' interest and value differ from their context-general measures in psychometric properties across countries. Using PISA2006 Science data, differential effects of item context on assessing interest and value were illustrated in both the individual and country levels. The main findings are as follows: First, correlation between context-specific and context-general measures tended to be slightly higher in value than in interest....

Nitrogen (N)-doped ordered mesoporous carbons (OMCs) with a dual transition metal system were synthesized as non-Pt catalysts for the ORR. The highly nitrogen doped OMCs were prepared by the precursor of ionic liquid (3-methyl-1-butylpyridine dicyanamide) for N/C species and a mesoporous silica template for the physical structure. Mostly, N-doped carbons are promoted by a single transition metal to improve catalytic activity for ORR in PEMFCs. In this study, our N-doped mesoporous carbons were...

This review presents current progress in the preparation methods of liquid crystalline nanocarbon materials and the liquid crystalline spinning method for producing nano-carbon fibers. In particular, we focus on the fabrication of liquid crystalline carbon nanotubes by spinning from superacids, and the continuous production of macroscopic fiber from liquid crystalline graphene oxide.

This study discusses two canceled dam projects, Youngwol Dam in South Korea and Two Forks Dam in Colorado of the United States. Both of them illustrate how the new paradigm applies to regional water projects because they became victims of environmental opposition in the new paradigm. While the cases have no apparent close relationships and they occurred in different decades, they offer interesting comparisons. They were basically struggles between water development coalitions and environmental...

This study attempted to explore the effects of partners' proficiency levels on test scores in paired English speaking test. Although the influence of interlocutor's effects on speaking test performance has been extensively researched in the previous studies, the findings have been inconsistent. The present study explored the effect of partners' proficiency levels on test scores in a paired speaking test. Participants included a total of 107 female adults and college students. Based on their...

The Korean government’s move to implement criterion-referenced assessment in secondary schools has impacted the nation socially and politically as well as educationally. Since education policy is a matter not of only education itself but of a nation’s politics, culture and economy, the issue of criterion-referenced assessment in secondary schools has been hotly debated before and even during its implementation. With the government’s interest in implementing criterion-referenced assessment in...
