Searching for an image conveying connotative meanings: An exploratory cross-cultural study

On the basis of the semiotics premise, this exploratory study examined cultural influences that pertain to the image search process when users have connotative needs. The study used the Semantic Differential, a quantitative tool for measuring affective reactions, as well as word-based analysis, to analyze responses to a survey questionnaire administered to twelve Korean and twelve American students. The results demonstrated that even when completing the same task, participants from different backgrounds have different tendencies in expecting and selecting a relevant image. The results supported the semiotics assertion that cultural context results in variations in interpreting the connotative messages of an image, and these variations are restricted by cultural boundaries. The study underlined the potential of using the Semantic Differential to enhance accessibility to connotative messages during the image retrieval process. Based on the findings, some suggestions for image retrieval system design were discussed. This study will broaden understanding of connotative messages in terms of image retrieval and user behaviors. The conclusions will contribute to designing a practical image retrieval system that can provide subject access to connotative messages.     

An online authoring tool for creating activity-based learning objects

As higher education increasingly relies on e-learning, the need for tools that will allow teachers themselves to develop effective e-learning objects as simply and quickly as possible has also been increasingly recognized. This article discusses the design and development of a novel tool, Enook (Evolutionary note book), for creating activity-based learning objects (LOs). This tool has three general foci: 1) creation of various activity-based objects for experimental learning or learning by doing while simultaneously offering as many learning resources as a real e-book that services as both a textbook and a notebook, dual functions that paperback books can never provide; 2) management of all aspects of live instructor-led classroom training in a network environment, such the Web and or a mobile network; 3) facilitated use of data on students’ progress to monitor their understanding of the material and to provide other meaningful information through learning analytics.     

A cross‐cultural comparison of student social attributions

One hundred sixty American and 397 Korean fourth‐ and fifth‐graders were administered the Student Social Attribution Scale (SSAS), designed to assess students' explanations for social successes and failures. A Korean version of the SSAS was developed for the study. The American and Korean instruments' internal consistency reliability were determined (rs ranged from .56 to .86 for the Korean instrument and .62 to .88 for the American instrument). The means from both the American and Korean SSAS versions on the 8 scales and global scores (e.g., internal, external) were compared. Based on the literature, Korean children should have had higher scores for effort attributions in failure situations than the American children and Americans should have shown higher scores for ability attributions in successful situations. In fact, Korean children did show significantly higher ( p < .005) Failure Effort scores and American children showed significantly higher ( p < .005) Success Ability scores. Findings indicate that Korean children are potentially more willing to accept responsibility for social failure than American students. © 2002 John Wiley & Sons, Inc.     

A sociocultural theoretical approach to understanding mentor–mentee interactions during a Teaching English as a Second Language practicum at the master’s degree level

Drawing on the sociocultural theoretical (SCT) perspective, we offer a microgenetic analysis of mentor–mentee interactions in the context of pre-service teachers’ practicum in a Master’s program for Teaching English as a Second Language (TESL). Following two pairs of mentors and mentees, we analyze audio-recorded interactions and interviews and examine in depth how mediation occurs during mentoring and how such mediation assists the mentees in learning to become teachers. Our findings show that mentors’ mediation is dynamic and contingent upon the context in which mentoring occurs and that the quality and character of mentor–mentee interactions during goal-directed activities is a critical feature of promoting the mentees’ learning. Responsive mediation especially plays a key role in promoting the mentees’ cognitive development, and it is an essential component of effective mentoring. This calls for a more SCT-informed approach to conceptualizing mentoring and training mentors in practicums.     

A Comparison of Item Fit Statistics for Mixed IRT Models

In this study we examined procedures for assessing model-data fit of item response theory (IRT) models for mixed format data. The model fit indices used in this study include PARSCALE's G² , Orlando and Thissen's S − X² and S − G² , and Stone's χ²* and G²* . To investigate the relative performance of the fit statistics at the item level, we conducted two simulation studies: Type I error and power studies. We evaluated the performance of the item fit indices for various conditions of test length, sample size, and IRT models. Among the competing measures, the summed score-based indices S − X² and S − G² were found to be the sensible and efficient choice for assessing model fit for mixed format data. These indices performed well, particularly with short tests. The pseudo-observed score indices, χ²* and G²* , showed inflated Type I error rates in some simulation conditions. Consistent with the findings of current literature, the PARSCALE's G² index was rarely useful, although it provided reasonable results for long tests.     

Korean Year 3 Children’s Environmental Literacy: A prerequisite for a Korean environmental education curriculum

The purpose of this study was to investigate Korean children’s environmental literacy levels and the variables that affect their environmental literacy. An instrument, the Environment Literacy Instrument for Korean Children (ELIKC), was developed that measures four different dimensions (knowledge, attitude, behaviour, and skills) using 69 items and 13 demographic variables. The ELIKC was administered to 969 Year 3 students from large cities, medium‐sized cities, and rural areas. The students were given 80 min to answer the questions. Statistical analysis was performed on each of the scales that make up the ELIKC and a multivariate analysis of variance was performed to identify the variables that affect environmental literacy. Results indicate that the correlation between attitude and behaviour is the strongest while that between knowledge and behaviour is the weakest. Also, it was found that gender, parents’ school background, and the source from where students obtain environmental information affect all categories of environmental literacy.     

Functions of Social Gatherings Involving Alcohol Consumption with Coworkers in Korea

Focusing on alcohol-involved social gatherings (i.e. drinking parties), the current study examined the reasons for and outcomes of joining drinking parties and evaluations of them. In studies 1 and 2, Korean workers (n=87) employed in the civil engineering industry and undergraduates (n=103) from various engineering majors provided desirable and undesirable reasons for and outcomes of joining drinking parties with their colleagues (coworkers for working adults and school friends for undergraduates). In studies 3 and 4, Korean workers (n=102) and undergraduates (n=89) evaluated each of the outcomes as either social, personal, or both. In study 5, Korean workers (n=108) and undergraduates (n=111) evaluated how good or bad each outcome type would be. Findings showed that among the five types of the drinking party participation outcomes, the conversation category and the work-/school-life category were the ones for which working adults and undergraduates had similar evaluations. For the group, the hierarchical relationship, and the drinking categories, however, working adults and undergraduates had different evaluations. These and other findings are presented in detail, and the implications thereof are discussed.

The determinants of private tutoring participation and attendant expenditures in Korea

With the growing worldwide prevalence of private tutoring, the causes and effects of private tutoring have been drawing increasing attention both academically and policy wise. This study intends to draw policy implications by investigating the determinants of private tutoring participation of school-aged children and expenditures per child for such private tutoring. The logistic regression (for participation), OLS, and F.E. panel models (for expenditures) were adopted for the analysis, using the Korean panel data. The empirical findings indicate that private tutoring for children—both in terms of participation and expenditures—has a positive correlation with the mother’s educational attainment (preference effect), a negative correlation with the mother’s employment status (time constraint effect), and a positive correlation with the household income (income effect).
