Multilevel analysis of the effects of student and course characteristics on satisfaction in undergraduate liberal arts courses

The purpose of this study is to analyze the effects of student and course characteristics on student satisfaction in courses by using a two-level hierarchical linear model (HLM). Based on literature reviews, 13 research variables (1 student gender, 2 student academic year, 3 student major, 4 student reason for taking the course, 5 student level of course participation, 6 student expected grade, 7 student achieved grade, 8 faculty gender, 9 faculty age, 10 faculty status, 11 academic field of the course, 12 class size, and 13 course type) were selected and specified as fixed effects in the analysis model. Data were 57,216 ratings of 1,481 undergraduate liberal arts courses at Seoul National University in 2006. The result of unconditional model analysis revealed that student characteristics’ effects on student satisfaction in courses (within-course effects, 88.1%) were much larger than course characteristics’ effects (between-courses effects, 11.9%). The result of conditional model analysis specifying student and course level predictors revealed that those 12 research variables, with the exception of student gender, had statistically significant effects on student satisfaction in courses. The explained variance was 22.0% in student level, 65.8% in course level, and 27.2% of the total variance. An earlier version of this paper was presented at the 8^th International Conference on Education Research, Seoul National University, Seoul, Korea, October 23–25, 2007.     

The vortex of multiculturalism in South Korea: a critical discourse analysis of the characterization of “multicultural children” in three newspapers

This study investigates how multicultural children have been portrayed by the Korean media, where the term is typically used to mean a child of an underprivileged Korean man and a female marriage migrant from a less industrialized neighboring country. Adopting the theoretical lens of critical discourse analysis, I examine news articles published from 2009 to 2013 in the Hankyoreh, the Hankook Ilbo, and the Chosun Ilbo: three daily newspapers representing a full range of progressive, moderate, and conservative political perspectives within society. Analysis reveals that multicultural children have been characterized as a marginalized group, as a threat to the future Korean society, or as global human resources. Given that these discourses are manifestations of underlying ideology, I also explore how these three discourses are conjoined with three competing ideologies in Korea; namely, democracy, nationalism, and neoliberalism. This study concludes by discussing how multiculturalism serves as a discursive framework through which democratic, nationalist, and neoliberal ideas gain their effectiveness.     

The Meaning of Social Inclusion for People with Disabilities in South Korea

This study sets out to examine and understand the meaning of social inclusion for people with disabilities, as constructed by people with disabilities themselves. Focus group interviews with 34 people who have physical impairments, cerebral palsy, or hearing or visual impairments were conducted for the study. Using the data obtained from these interviews, the interviewees’ various definitions and perceptions of social inclusion were analysed and four meaning categories for social inclusion were identified: excluded/segregated, present, participating, and actively participating. The findings of this research can be used as foundational material in the development of disability policies and the improvement of social services to better enable full social participation and social inclusion for people with disabilities.     

Student response to tuition increase by academic majors: empirical grounds for a cost-related tuition policy

This study explored the responses of students in different academic majors to tuition increase, with a particular focus on the relationship between tuition increase, and future earnings and college expenditures. We analyzed effects of tuition increase on enrollment in six academic majors—Engineering, Physics, Biology, Mathematics, Business, and Education—where disciplinary enrollment data were available. The main findings are that students are elastic to tuition level in Physics, Biology, and Business, but not in Engineering, where the rate of return is the highest among the six majors and the college expenditure are the highest. The findings suggest that student enrollment in various academic majors is affected differentially by tuition. Further, the findings support a cost-related tuition policy, one designed to charge students higher tuition for higher-cost majors and lower tuition for lower-cost majors.

Access to local books: the effects of Read Malawi from a children's rights perspective

Children in low‐income, postcolonial countries such as Malawi have few opportunities with quality reading materials that promote independence as readers. In this study, we argue that access to locally produced text relevant to linguistic and cultural contexts is a fundamental human right for children throughout the world. Situating this study within the intersection of research on children's rights and complementary reading materials, we analyse data from a project in Malawi. We consider the ways in which a respect for children's educational rights – specifically, their rights to access information via children's books – can help them develop their biliteracy. Additionally, we examine how the Read Malawi program contributes to Malawian children's literacy development in both national and official languages. Our findings suggest not only a humanistic need for quality complementary books, but also the empirical justification for books in the hands of children; in particular, an interconnected relationship between borrowing books from school and engagement with Read Malawi was found, especially when we explore children's English proficiency. Through Read Malawi, this study exemplifies what a quality literacy intervention can do in supporting children's Chichewa and English proficiency and improving their rights to quality education.     

Psychosocial factors influencing competency of children's statements on sexual trauma

Objectives

The objectives of this study are to assess children's competence to state their traumatic experience and to determine psychosocial factors influencing the competency of children's statements, such as emotional factors of children and parents and trauma-related variables, in Korean child sex abuse victims.

Methods

We enrolled 214 children, who visited “Sunflower Children's Center” for sexual abuse. The children were aged 8-13 years. The children's parent were surveyed using questionnaires [Beck Depression Inventory (BDI), State-Trait Anxiety Inventory(STAI)] to obtain demographic information, traumatic event profiles and self-report scale. Children completed psychological measures as follows: Children's Depression Inventory (CDI), Revised Children's Manifest Anxiety Scale (RCMAS), Traumatic Symptom Checklist for Children (TSCC). The modified-Criteria-Based Content Analysis (CBCA) was used to assess children's statements. ANOVA, independent t-test, Pearson correlation were used. All statistics were demonstrated using SPSS 12.0.

Results

Modified-CBCA scores did not differ according to children's level of depression and anxiety. Children with parents who showed supportive reactions, scored significantly higher on the modified-CBCA scores than those with unsupportive parents. Children with severely depressed parents had lower modified-CBCA scores than those with less depressed parents. Modified-CBCA scores were significantly higher in participants who experienced a single traumatic event than those who had multiple events. However, the severity of sexual abuse, relationship with the perpetrator, types of disclosure, and duration of initial disclosure did not show significant differences in capability of statement.

Conclusion

In conclusion, the competence of statements in Korean sexually child sex abuse victims is related to parental emotional states and support rather than children's factors such as psychopathology or age, and appears to be more reliable with a single traumatic experience. Therefore, promoting parental support through psychoeducation is one of the most important things to be done to help children overcome psychologic trauma but also enhance the accuracy of their statement.     

A Web-based on-machine mould matching and measurement system based on CAD/CAM/CAI integration

INTRODUCTION Today, the manufacturing industry makes con- stant effort in order to construct an E-manufacturing system using information technology for effective production control, and then, it offers the integrated production control to the workers, the production managers, and the consumers, etc. (Lee, 2003; Choi, 2004). In the mould manufacturing industry, the process managers often request paperwork to know the information of the processes on CNC machine tools or they visit the shop…     

comparison of three growth modeling techniques in the multilevel analysis of longitudinal academic achievement scores: Latent growth modeling, hierarchical linear modeling, and longitudinal profile analysis via multidimensional scaling

This study introduces three growth modeling techniques: latent growth modeling (LGM), hierarchical linear modeling (HLM), and longitudinal profile analysis via multidimensional scaling (LPAMS). It compares the multilevel growth parameter estimates and potential predictor effects obtained using LGM, HLM, and LPAMS. The purpose of this multilevel growth analysis is to alert applied researchers to selected analytical issues that are required for consideration in decisions to apply one of these three approaches to longitudinal academic achievement studies. The results indicated that there were no significant distinctions on either mean growth parameter estimates or on the effects of potential predictors to growth factors at both the student and school levels. However, the study also produced equivocal findings on the statistical testing of variance and covariance growth parameter estimates. Other practical issues pertaining to the three growth modeling methods are also discussed.
