Two-Step Approach to Partial Factorial Invariance: Selecting a Reference Variable and Identifying the Source of Noninvariance

To date, no effective empirical method has been available to identify a truly invariant reference variable (RV) in testing measurement invariance under a multiple-group confirmatory factor analysis. This study proposes a method that, in selecting an RV, uses the smallest modification index (min-mod). The method’s performance is evaluated using 2 models: (a) a full invariance model, and (b) a partial invariance model. Results indicate that for both models the min-mod successfully identifies a truly invariant RV (Study 1). In Study 2, we use the RV found in Study 1 to further evaluate the performance of item-by-item Wald tests at locating a noninvariant variable. The results indicate that Wald tests overall performed better with an RV selected in a partial invariance model than an RV selected in a full invariance model, although in certain conditions their performances were rather similar. Implications and limitations of the study are also discussed.     

Wisdom from Korean Reentry Counseling Professionals: A Phenomenological Study of the Reentry Process

The purpose of this phenomenological study was to explore the common experience of Korean counseling professionals who returned to South Korea after obtaining their doctoral degrees in the United States. Individual semi-structured interviews were conducted with ten Korean counseling professionals to understand their cross-cultural experience. The data were analyzed by phenomenological methods of inquiry. Seven themes emerged from the analyses: Reminiscence, Differences and Comparisons, Benefits, Challenges, Coping, Application and Modification, and Meaning. The findings suggested how the setting and context in which the reentry process occurred contributed to the participants’ experience as well as the essence of the reentry process. Implications of the results are discussed in the light of cross-cultural counseling and for future research and practice.     

Students’ perception of EdD and PhD programmes in Hong Kong

Abstract

The aim of this study is to explore the learning experiences of students enrolled on a Doctorate in Education programme in Hong Kong. The main questions are as follows. How do EdD students position themselves as doctoral candidates? How do EdD students experience their education in terms of scholarly expertise and scholarly identity? How do EdD students characterise their relationships with their supervisors? What perceptions do PhD students hold of the field of knowledge of EdD students and the value of an EdD degree? The data obtained from 10 semi-structured interviews in one selected institution are discussed with reference to the four main themes; distinction between EdD and PhD degrees: ‘co-existent’ vs. ‘separate’; positioning of EdD programme: title of doctor as ‘unfair’ vs. ‘deserved’; scholarly value: ‘insightful’ vs. ‘non-academic’; and relationship with supervisor: ‘independent and self-managed’ vs. ‘never equal, unlike the relationship between PhD student and supervisor’.     

Exploring regional and institutional factors of international students' dropout: The South Korea case

With an increasing number of international students in South Korea, the issue of retaining these students and reducing their dropout rates has become important. This study explores the multilevel factors that affect the institutional dropout rate among international students in Korea. The research questions are as follows: (a) to what extent do international students drop out from undergraduate or short‐term programmes in Korean universities?; (b) what are the regional and institutional factors that determine international students' dropout rates? This study uses the panel data on educational institutions as found in the Higher Education in Korea report, which has been updated annually by the Ministry of Education since 2013. According to the pooled ordinary least square and panel analyses, the results indicate that a range of institutional factors (such as type, size, tuition and research performance of academics) and regional factors (such as regional gross domestic product, inflation and the numbers of foreigners in the region) are all associated with the dropout rates of international students. This study suggests that we need to consider various factors to improve the international students' learning experiences both inside and outside of the campus.     

Research productivity by career stage among Korean academics

This study explores Korean academics’ changes in research productivity by career stage. Career stage in this study is defined as a specific cohort based on one’s length of job experience, with those in the same stage sharing similar interests, values, needs, and tasks; it is categorized into fledglings, maturing academics, established academics, and patriarchs. Academics’ research productivity in each career stage is analysed, and these characteristics are compared across academic disciplines. In addition, the factors influencing research productivity in different career stages are examined. The results indicate that research productivity among academics changes according to their career stage, and its pattern differs across academic disciplines. Thus, there is a need to provide proper reward systems or career development programs in consideration of such differences.     

Early Childhood Preservice Teachers' Use of Verbal and Non-Verbal Guidance Strategies Across Classroom Contexts

Observations of preservice teachers often lack information about specific strategies they use when guiding children's behavior. This study investigated how preservice teachers used verbal and non-verbal behavior modification techniques within structured and transition classroom contexts. Using an on-the-mark 20-second observe and 10-second record method, eleven preservice teachers were observed in classrooms for two morning hours. A repeated measures MANOVA revealed two significant two-way interactions, which included types of modification techniques and types of contexts (Wilks's λ = .38, F(2, 9) = 7.37, p .05, Cohen's f = .88) and types of communication skills and types of contexts (Wilks's λ = .64, F(1, 10) = 5.53, p .05, Cohen's f = .74). Implications for future research and practice include more focused observations of preservice teachers and children's responses to various verbal and non-verbal strategies along with more education about how to use positive guidance strategies in real-life classroom situations.     

Girls and computer science: experiences,perceptions, and career aspirations

The purpose of this mixed methods study was to examine ways to promote computer science (CS) among girls by exploring young women’s experiences and perceptions of CS as well as investigating factors affecting their career aspirations. American girls aged 10–16 participated in focus group interviews as well as pre-, post-, and follow-up surveys while attending a CS camp. The analysis of data revealed that although the participants were generally positive about the CS field, they had very limited knowledge of and experience with CS, leading to little aspiration to become computer scientists. The findings also indicated that girls’ affinity for and confidence in CS were critical factors affecting their motivation for pursuing a CS-related career. The study demonstrated that participation in the CS camp motivated a small number of participants to be interested in majoring in CS, but the activity time was too short to make a significant impact. Based on the findings, we suggest that providing CS programming experiences in K-12 classrooms is important in order to boost girls’ confidence and interest in CS.     

Prelinguistic vocal development in young cochlear implant recipients and typically developing infants: year 1 of robust hearing experience

This investigation examined the time course and sequence of prelinguistic vocal development during the first year of cochlear implant (CI) experience. Thirteen children who were implanted between 8 and 35 months and 11 typically developing (TD) infants participated in this longitudinal study. Adult-child play interactions were video- and audio-recorded at trimonthly intervals for each group, and child utterances were classified into categories representing progressively more mature productions: Precanonical Vocalizations, Basic Canonical Syllables, and Advanced Form vocalizations. Young CI recipients met the 20% criterion for establishment of the Basic Canonical Syllables and Advanced Forms levels with fewer months of robust hearing experience than the TD infants. Most CI recipients followed the sequence of development predicted by the Stark Assessment of Early Vocal Development-Revised. The relatively rapid progress of the CI children suggests that an earlier period of auditory deprivation did not have negative consequences for prelinguistic vocal development. It also supports the notion that young CI recipients comparatively advanced maturity facilitated expeditious auditory-guided speech development.
