Purpose: This study examines changes in developmental profiles of children with language delay over time and the clinical significance of assessment conducted at age 2-3 years. Methods: We retrospectively reviewed the medical records of 70 children (62 male, 8 female), who had visited the hospital because of delayed language development at 2-3 years, and were reassessed at ages 5-6. Language and cognitive abilities were assessed using multiple scales at the initial and follow-up visits. Results: At the initial test, 62 of the 70 children had mental development index (MDI) below 70 of Bayley Scales of Infant Development Test II. Of the 62 children in the follow-up assessment, 30 children (48.4%) remained within the same cognitive range (full-scale intelligence quotient, FSIQ<70 of Wechsler preschool and primary scale of intelligence), 12 had borderline intellectual functioning (FSIQ, 70-85), 6 improved to average intellectual functioning (FSIQ>85), and 5 had specific language impairment, 9 had autism spectrum disorders. At the initial test, 38 of the 70 children had cognitive developmental quotients (C-DQ) below 70. Of the 38 children in the follow-up assessment, 23 children (60.5%) remained within the same cognitive range (FSIQ<70). The correlation coefficient for MDI and FSIQ was 0.530 (P<0.0001) and that for C-DQ and FSIQ was 0.727 (P<0.0001). There was a strong correlation between C-DQ and FSIQ, and a moderate correlation between MDI and FSIQ. Conclusion: Low MDI scores reflect a specific delay in cognitive abilities, communication skills, or both. The C-DQ, receptive language development quotient, and social maturity quotient also help to distinguish between children with isolated language delay and children with cooccurring cognitive impairment. Moreover, changes in the developmental profile during preschool years are not unusual in children with language delay. Follow-up reassessments prior to the start of school are required for a more accurate diagnosis and intervention.

Recently, corpus assisted vocabulary instruction has been attracting a lot of interest. Most studies have focused on understanding language learners' receptive vocabulary knowledge. Limited attention has been paid to learners' productive competence. To fill this gap, this study attended to learners' productive lexical development in terms of form, meaning and use respectively. This study introduced EFL learners to the corpus-based language pedagogy to learn COVID-19 theme-based vocabulary. To investigate the gains and views of 33 EFL first-year college students, a sentence completion task and a questionnaire were developed. Learners' productive performances in the three lexical knowledge aspects (i.e., form, meaning and use) were particularly targeted. The results revealed that the students achieved significant gains in all aspects regardless of their proficiency level. In particular, the less proficient students achieved greater knowledge retention compared with their highly proficient counterparts. Meanwhile, students showed positive attitudes towards the corpus-based approach to vocabulary learning.

본 연구는 미국영어 화자의 평균적 음향 스펙트럼 분포를 확보한 후 과학영재학교 재학생의 영어발화 양상을 비교하여 상대적으로 우수한 지적 역량을 갖춘 우리나라 과학영재들의 초분절적 영어 유창성 양상을 규명하고, 그 근접성 정도가 영재학교 학생의 영어 과목 정기고사 성취도와 어떤 관계성을 갖는지 탐구하고자 진행되었다. 불과 수 초에서 수십 초에 불과한 음성녹음 데이터 위주로 분석을 시행했던 종래의 연구와 달리 총 4시간에 달하는 미국영어 원어민 화자(남성 15명, 여성 15명)의 음성녹음 자료를 MATLAB(R2022a; The Math Works) 코드로 분석하여 20 -20,000 Hz 주파수 범위 내의 대역별로 장기 스펙트럼 음향에너지 분포값을 확보했으며, 이를 기준으로 과학영재학교 1학년 신입생 80명의 녹음데이터 LTASS(long-term average speech spectrum) 분석 수치와 비교한 결과, 영어 과목 학기말고사의 학업성취도 수준이 상위 30% 이내인 학생들의 표본을 제외하고는 미국영어 음향에너지 분포와의 근접성이 통계적으로 유미하지 않다고 밝혀졌다. 영재학교 입학 후 영어 성취도를 예측하기 위한 지표를 발견하기 위해 수용성 어휘크기검사(receptive vocabulary size test), 학기 중 복수 회 실시한 영어 어휘 형성평가 퀴즈 누적 점수, 공인 영어말하기시험(English Speaking Proficiency Test, ESPT) 성취도를 추가 변량으로 하여 정기고사 성취도와의 상관관계 분석 및 각 변량 간 선형 회귀분석을 시행하였는데, 대개 유년시절 완성되는 영어 유창성을 측정하는 ESPT보다는, 1학기 및 2학기 초 실시한 수용성 어휘크기검사 및 수과학 분야 저빈도 어휘 위주 형성평가 점수와의 통계적 유의성이 월등히 높다는 사실이 관찰되었다. 따라서, 본 연구로부터 확보된 이론적 기반을 토대로 국내 영재학교에서는 발음교육보다 과학영재를 주요 대상으로 한 전문적 수준의 저빈도어휘 교육이 보다 효과적인 교수 요목이라 추정할 수 있다.

The purpose of the study was to prove the effect of the "Picture Book Reading Program for Mothers" developed to enhance the language competence of married immigrant women and their children. Twenty immigrant mothers with three-year-olds were recruited, and they participated in an 8-week-Picture Book Reading Program developed by the reseacher. The REVT and U-TAP were used to measure linguistic abilities for mothers while PRES was used to measure their children's linguistic abilities. Lee(2004)'s "Effect of dialogic picture book reading teacher training program for toddlers" was used to measure the mother's and children's verbal and non-verbal behaviors. The results of the study were as follows: First, by participating in the PBRPM, the mother's linguistic ability as well as children's vocabulary and receptive language have increased. Second, by participating in the PBRPM in terms of mother-child interaction, mother's verbal behaviors to children (i.e. attention and inquiring) and children's verbal behaviors(i.e. responding and imitation) have increased. In conclusion, "PBRPM" for married immigrant women and their children proved to be effective in enhancing the language competence and verbal interactions between married immigrant women and their children.

A total of 31 mothers of 5-month-old infants(18 boys and 13 girls) were observed and interviewed at home via a questionnaire format. Results revealed that perceived maternal parenting style had an effect on general infant general development. As mother exhibited more didactic and limit setting behaviors, the infants showed more receptive, expressive, and language development characteristics. Furthermore, the effects of maternal sensitivity on infant general development and language skills were also ascertained. The infants who showed more positive general development had mothers who interacted sensitively with them. Maternal sensitivity was the only factor that had a major effect on infant general development. The overall findings of this study indicate that perceived maternal parenting style and observed maternal sensitivity were found to have positive effects on general infant general development and language skills.

This study explores reading fluency among elementary school students considering language level and family income(low SES). Forty eight students from 1st to 3rd grades participated in two paragraph reading tasks. Half of the children were from low income family and half of the children had low lexical knowledge. Reading fluency as in the number of correctly read syllables per minute, the total error frequency and error types were used to compare group differences. There were significant differences in the number of correctly read syllables per minute between two income groups and two language groups. There was a significant difference between low income group and non-low income group in total number of errors only when children's lexical knowledge were low. There were no group differences in error types of repetition and omission. Substitution and insertion error seemed to reflect the total error pattern. These results imply the importance of early screening and early involvement for children with low lexical knowledge from low income family. Monitoring and early intervention will support these children's reading development.

The primary goal of the study was to provide some preliminary validity evidence for the Vocabulary Grade Levels Test (Busan Metropolitan City Office of Education, 2009), which is designed to measure the receptive vocabulary knowledge of learners in L2. For the purpose of the current study, 327 participants at the elementary school participated in the study and were asked to take two different vocabulary tests. Namely, a Vocabulary Size Test (Nation, 2001) and a Vocabulary Grade Levels Test. The data were analyzed using correlation in order to discover the relationship between these two types of tests. Following this, the Rasch analysis was conducted to examine the reliability and validity of the measurement in question. The data analysis showed that both grade separation reliability and item separation reliability were high, indicating that the Vocabulary Grade Levels Test well discriminates learners with a wide range of proficiency levels. The findings of the study are discussed, along with further improvements in order to ascertain the validity of this particular vocabulary test.
