This research has its basis with focus on the way Korean native speakers recognize Chinese Korean-learners' pronunciation. The objective of the study is to lay the cornerstone for establishing effective teaching-learning strategies for the education of the Korean phonetic system. In this study, the results of the experiment are presented which shows how native speakers of Korean identify Chinese Korean-learners' pronunciation of consonants. In the first place, stimulation tones were created from the original utterances of Chinese Korean-learners and seven scripts were made through the Pratt program. In addition, the subjects were asked to choose what the phonetic materials sounded like. The results of the research are represented as the ratio of frequency of Korean native speakers' response to each utterance to the total frequency. In addition, the paired t-test was taken in order to explore any relatedness to the changes in the level of proficiency of the Korean phonetic system, ranging from beginners to advanced learners. The outcome shows that the mistakes which Chinese Korean-learners make in pronouncing the consonants of Korean are relatively well-reflected in Korean native speakers' auditory cognitive reactions. To put it concretely, there is some difficulty in differentiating lax consonants from aspirates in the cases of plosives and affricates, but relatively little trouble with fortes. However, it is revealed that there is also a slight difference in relation to articulatory positions in detailed aspects. To provide an effective teaching method for the Korean phonetic system, it is essential to comprehend learners' phonetic mistakes through the precise analysis of data in terms of 'production.' Also, a more meticulous observation of 'phenomena' must be made through verification from the view of 'reception,' as attempted in this study. A more thorough diagnosis by applying methodology makes it possible to lay the foundation for developing effective teaching-learning strategies for the instruction of the Korean phonetic system. This study has its significance in making such attempts.

This paper addresses the question of why prepositions are particularly difficult forEFL learners. The first reason for such difficulty lies in the distinction between seemingly equivalent prepositions such as to and with, as in compared to and compared with. Most monolingual learners' dictionaries regard these two phrases as virtually synonymous. Yet, the results of the corpus analysis conducted in this study indicate that there are differences between the two. A second reason why EFL learners have problems with prepositions is that there are often variations in the inputdata. For example, although from generally follows different, in American English different than is also used. On the other hand, in British English, different to is the second most commonly used construction. This type of regional variation, confirmed in the corpus findings of the present paper, causes confusion in students of English. A learner who is not accustomed to British English may be puzzled by the expression different to. Finally, L1 negative transfer is responsible for the incorrect use of expressions such as discuss about. An error of this sort is the result of interference from the learner's mother tongue. The English verb discuss is not subcategorized for a preposition, whereas the equivalent Korean verb, for example, requires a noun phrase combined with the postposition.

This study aimed to discover the affective ability of students by applying a thematic project model concerning the marine field unit of science for third grade middle school students from among diverse methods of realizing STEAM education. Also, based on this, STEAM education is a new type of learning including the process of exploring by oneself, presenting, discussing and mutually evaluating by becoming an independent person in learning As the results of the study are as follows: First, the STEAM class applied with a thematic project model was discovered to promote a learning attitude toward science by learners. Second, the STEAM class applied with a thematic project model was shown to be effective in improving the self-directed learning characteristics of learners. Third, STEAM education applied with a thematic project model was found to promote learners' motivation for learning science. This may be an effective method for learners who have felt difficulty in the science curriculum or have not been interested in the curriculum by triggering voluntary motivation.

The present study examines the auditory boundary between Korean /o/ and /u/ on a synthesized vowel continuum by Chinese learners of Korean language. Preceding researches reported that the Chinese learners have difficulty pronouncing Korean monophthongs /o/ and /u/. In this experiment, a nine-step continuum was resynthesized using Praat from a vowel token from a recording of a male announcer who produced it in isolated form. F1 and F2 were synchronously shifted in equal steps in qtone (quarter tone), while F3 and F4 values were held constant for the entire stimuli. A forced choice identification task was performed by the advanced learners who speak Mandarin Chinese as their native language. Their experiment data were compared to a Korean native group. ROC (Receiver Operating Characteristic) analysis and logistic regression were performed to estimate the perceptual boundary. The result indicated the learner group has a different auditory criterion on the continuum from the Korean native group. This suggests that more importance should be placed on hearing and listening training in order to acquire the phoneme categories of the two vowels.

We took note of the fact that there were not many studies on improvement of mathematics learning in the field of statistics for the minority students from the families who belonged to the Low-SES. This study was to help them understand the concepts and principles of mathematics, motivate them for mathematics learning, and have them feel familiar with it. The subjects were 12 students from the low-SES families among the sophomores of 00 High School in Gyeonggi-do. Although it could not be achieved effectively in the short-term of learning for the slow learners, their understanding of basic concepts and confidence, interests and concerns in statistical learning were remarkably changed, compared to their work in the beginning period. Our discourse classes using various topics and examples were well perceived by the students whose performance was improved up to the 3rd thinking level of Mooney's framework. Also, a meaningful instructional model for slow learners(IMSL) was found through the discourse.

본 논문에서는 망각곡선을 응용한 반복학습시기 설정 및 학습자 수준과 단어 난이도 자동계산 방법이 적용된 영어단어 암기시스템을 소개한다. 우리 시스템은 망각곡선을 사용해서 학습자의 단어암기 횟수에 따라 적절한 반복 주기를 정하고 그 시기에 복습을 요구한다. 학습자가 알고 있는 단어들에 대한 복습시간을 없애고 잊어버릴 확률이 가장 높은 단어들을 우선 적으로 복습하는 것으로 시간을 절약 할 수 있는 것이다. 또 수준에 맞는 난이도의 단어들을 제공함으로써 학습 흥미와 성취도 유지에 기여할 수 있다. 학습자의 수준을 고려하지 않은 난이도의 단어를 무작위로 제공하거나 이미 다른 사람들의 평가에 맞춰진 난이도의 단어들을 제공하는 기존의 시스템과 차별되도록 학습자와 단어 난이도 설정에 온라인 체스게임 랭킹시스템에서 사용하고 있는 "Glicko" 시스템을 적용시켰다. 플레이어간의 대결을 통해서 서로의 실력이 결정되고 매칭되는 이 시스템을 우리는 단어와 사람간의 대결로 시스템에 적용하였다. 그것으로 인해 학습하는 사람의 수준과 단어들의 난이도가 실시간으로 측정되고 학습과정에 반영이 된다. 이 외에 부가적으로 분산학습, 시험형식의 문제풀이의 즉각적인 피드백을 활용하여 영어 단어 암기의 효율성을 극대화 한다.

Purpose: It is intended to investigate the satisfaction of dental hygiene students with non-face-to-face online classes and use them as basic data for successful lecture design and operation. Methods: The data collected in this study were analyzed using the lBM SPSS Statistics 21 program. The general characteristics of the study subjects were frequency analysis, non-face-to-face online class satisfaction, and test satisfaction were frequency analysis and technical statistics. Through the independent sample T test, a t-test was conducted to find out whether there was an average difference in online class and test satisfaction according to grade. Results: The advantages of non-face-to-face online classes were that repetitive learning was possible (57.7%), the disadvantage was that there was a lack of real-time communication (74.9%), and the most efficient teaching method was a mixed form of online and face-to-face classes (64.9%). The satisfaction level of online classes was 2.69 points for 'self-directed learning habits,' which was the highest compared to the overall average of 2.55 points, and 2.09 points for 'difficulty in interaction between instructors and learners in online classes.'Non-face-to-face test satisfaction was 2.68 points for 'short test time gives fairness to test results,' higher than the overall average of 2.45 points, and 2.07 points for 'no difficulty accessing the test.'In terms of satisfaction with the non-face-to-face test according to the grade, it was found that the third grade showed a more negative attitude than the second grade in terms of sexual fairness (p<0.05). Conclusions: Through the above results, non-face-to-face online classes require various content development and some mixed classes considering the level of students, and instructors' efforts to improve the quality of classes for interaction between instructors and learners are needed.

본 연구의 목적은 수학 문장제 해결에 기초가 되는 수학과 용어의 유형에 따른 한국어학습자의 이해 특성 및 오류유형을 파악하여 한국어학습자의 문장제 해결에 효과적인 교수·학습 지도 방안 마련을 위한 기초 자료를 제공하는 것이다. 이를 위해 학교에서 별도의 한국어 수업을 듣는 한국어학습자 4명을 대상으로 교육과정 등재 용어와 교과서에 사용된 교육과정 미등재(정의/무정의) 용어에 대한 구체적인 개념이미지를 분석하는 사례 연구를 하였다. 연구 결과 첫째, 한국어학습자가 수학과 용어에 대하여 적합한 개념정의를 정립할 수 있도록 충분한 시각화 자료를 활용하여 지도할 필요가 있다. 둘째, 한국어학습자의 가정 내 사용 언어와 수학과 용어에 대한 적합한 개념이미지 형성 사이의 구체적인 관계를 파악할 필요가 있다. 셋째, 능동형 용어보다 의미 이해에 어려움을 겪고 있는 피동형 용어에 주의하여 지도할 필요가 있다. 넷째, 일상의 의사소통에 어려움이 없는 한국어학습자의 경우에도 수학 교과서에 사용되는 교육과정 미등재 일상어에 대하여 지도할 필요가 있다. 다섯째, 용어에 대한 설명에서 나타난 한국어학습자의 언어적 특성이 반영된 오류 유형을 고려하여 수학과 용어를 지도해야 할 것이다. 이러한 인식은 언어적 배경이 다른 한국어학습자의 문장제 해결 지도에 도움이 될 것으로 기대된다.
