College Adjustment Difficulties and the Overt and Covert Forms of Narcissism

Overt narcissism correlated negatively with emotional distress and interpersonal difficulties among female, but not male, students. After controlling for self‐esteem, overt narcissism correlated positively with depression among female students and with emotional distress and interpersonal difficulties among male students. Covert narcissism correlated positively with emotional distress and interpersonal and academic difficulties among both male and female students. Associations between covert narcissism and emotional distress and interpersonal difficulties remained after controlling for self‐esteem.     

The estimation of the IRT reliability coefficient and its lower and upper bounds, with comparisons to CTT reliability statistics

The primary purpose of this study is to investigate the mathematical characteristics of the test reliability coefficient ρ _XX′ as a function of item response theory (IRT) parameters and present the lower and upper bounds of the coefficient. Another purpose is to examine relative performances of the IRT reliability statistics and two classical test theory (CTT) reliability statistics (Cronbach’s alpha and Feldt–Gilmer congeneric coefficients) under various testing conditions that result from manipulating large-scale real data. For the first purpose, two alternative ways of exactly quantifying ρ _XX′ are compared in terms of computational efficiency and statistical usefulness. In addition, the lower and upper bounds for ρ _XX′ are presented in line with the assumptions of essential tau-equivalence and congeneric similarity, respectively. Empirical studies conducted for the second purpose showed across all testing conditions that (1) the IRT reliability coefficient was higher than the CTT reliability statistics; (2) the IRT reliability coefficient was closer to the Feldt–Gilmer coefficient than to the Cronbach’s alpha coefficient; and (3) the alpha coefficient was close to the lower bound of IRT reliability. Some advantages of the IRT approach to estimating test-score reliability over the CTT approaches are discussed in the end.     

Socio-political influences on EFL motivation and attitudes: comparative surveys of Korean high school students

This paper investigates Korean high school students’ English learning motivation and attitudes. In this regard, the results of a 2002 study were compared with those of a 2006 study. Questionnaire data were obtained from a total of 1,037 high school students in a major city in South Korea, and the data were compared with those on the students’ English proficiency. Statistical analyses verified two distinctive Korean-specific constructs: competitive motivation and attitudes toward Americans among the participants. The results suggest that negative washback effects of the College Scholastic Ability Test in Korea and influences of peer group cohesion, mass media, and the Information Technology (IT) infrastructure play a crucial role in EFL motivation and attitudes among Korean high school students.     

Random-Groups Equating with Samples of 50 to 400 Test Takers

Five methods for equating in a random groups design were investigated in a series of resampling studies with samples of 400, 200, 100, and 50 test takers. Six operational test forms, each taken by 9,000 or more test takers, were used as item pools to construct pairs of forms to be equated. The criterion equating was the direct equipercentile equating in the group of all test takers. Equating accuracy was indicated by the root-mean-squared deviation, over 1,000 replications, of the sample equatings from the criterion equating. The methods investigated were equipercentile equating of smoothed distributions, linear equating, mean equating, symmetric circle-arc equating, and simplified circle-arc equating. The circle-arc methods produced the most accurate results for all sample sizes investigated, particularly in the upper half of the score distribution. The difference in equating accuracy between the two circle-arc methods was negligible.     

Transnational academic mobility,knowledge, and identity capital

This article begins with the contemporary context of transnational academic mobility, and sketches a typology of mobile academics according to their self-identification. UK examples are offered as the main case study here. The article will then explore the relations of mobile academics and their embodied and encultured knowledge. It employs a concept of ‘transnational identity capital’ to discuss the position of transnational mobile academic intellectuals as a ‘stranger’ as inspired by Simmel's sociology of space.     

History of Science as an Instructional Context: Student Learning in Genetics and Nature of Science

This study (1) explores the effectiveness of the contextualized history of science on student learning of nature of science (NOS) and genetics content knowledge (GCK), especially interrelationships among various genetics concepts, in high school biology classrooms; (2) provides an exemplar for teachers on how to utilize history of science in genetics instruction; and (3) suggests a modified concept mapping assessment tool for both NOS and GCK. A quasi-experimental control group research design was utilized with pretests, posttests, and delayed posttests, combining qualitative data and quantitative data. The experimental group was taught with historical curricular lessons, while the control group was taught with non-historical curricular lessons. The results indicated that students in the experimental group developed better understanding in targeted aspects of NOS immediately after the intervention and retained their learning 2 months after the intervention. Both groups developed similar genetics knowledge in the posttest, and revealed a slight decay in their understanding in the delayed posttest.     

A Multi-Level Assessment of the Impact of Orientation Programs on Student Learning

The purpose of this study was to investigate the influence of orientation programs on student academic and social learning. Moving beyond previous studies, we examined how participation in orientation programming affected student learning and how the impact of these programs on learning varied by organizational characteristics (i.e., institutional control, size of undergraduate enrollment, sponsoring division, and whether the institution has an office designated for managing orientation programs), student entry characteristics (i.e., gender, race, transfer status), and student experiences (i.e., perceived quality of orientation program in helping student transition and in meeting students’ expectations, positive experiences with orientation staff, and perceptions of orientation programs and their efficacy in helping students navigate resources and in providing useful campus-based information). Hierarchical linear analysis was used to analyze these cross-level effects. Results demonstrated that having a designated office for orientation programs on campus was important for narrowing the academic learning gap between new-first year and transfer students. Implications for researchers and practitioners were discussed.
