Definitions of Routines Revisited

류도형(Do Hyung Ryu) 한국영어어문교육학회 2014 영어어문교육 Vol.20 No.4

The purpose of this paper is to reconsider current definitions and research directions about routines. In this paper, a problem statement about scholars' research findings about routines is made. It is pointed out that their interpretations of routines lack psychological reality. They believe that routines would be perceived as single language units which are then useful in communication. However, it could be said that people don't use routines because of their usefulness; the use of routines is habitual and natural and they are used regardless of usefulness. Based on a literature review of recent research, how routines are generated and developed will be considered. Also the new concept of routines will be proposed as the relationship between lexical units and chunks. Lastly, in regard to educational implication, it is suggested to teach English with movies to maximize the social features and developmental effects of routines. Movies are a kind of society in which there exist social values. To discover social values in movies is to get close to routines, which leads to language development. Further research should be undertaken in order to learn more about the relationship between language users and the routines they use.

영어 단어결합체(Word Combinations)와 청킹화(Chunking): 블록(Block)개념의 적용

류도형 ( Ryu Do Hyung ) 대한언어학회 2018 언어학 Vol.26 No.2

There is agreement that many word combinations are multiword units stored in long-term memory and retrieved as chunks. There is also increasing evidence that these formulaic language units are integral to first and second language acquisition. This is based on the view of chunking in the cognitive process, which can be utilized to overcome the limitations of working memory and increase its capacity. This study suggests that the chunking process should be the core basis of the learning and teaching of English in classrooms. The present study describes the -chunking process, word combinations, and the block concept of computer languages, based on block-based coding. A block puzzle activity was developed to use chunking with word combinations, an approach applied from the concept of block coding. The purpose of this study is to investigate the possibility and effectiveness of facilitating memorization of word combinations by a block puzzle activity based on the chunking process. The experiment results indicate that students recalled expressions of word combinations better. The findings have implications for EFL teaching and activity design purposes.

반복적 점화이론 기반의 단어결합체 활용 EFL 교수법

류도형 ( Do Hyung Ryu ) 21세기영어영문학회 2019 영어영문학21 Vol.32 No.2

The purpose of this paper is to present a method to effectively access combinations of words based on Hoey’s (2005) Lexical Priming (LP). Repetition priming, which is a subdivision of LP, is a tool that can be used in an EFL context. Five English major students of advanced or high intermediate proficiency participated in this case study. An American romantic movie, Crazy, Stupid, Love (Ficarra & Requa, 2011) was used, with four scenes of the movie selected for this study. Participants had to complete three stages. The first was a prime word confirmation stage in which all participants identified familiar words or expressions. The second was a context confirmation stage in which they confirmed how familiar expressions were used in context. The third was a recall stage in which the participants recalled familiar expressions. This stage was used to check participants’ access to combinations of words. Among the three stages, the context confirmation stage was found to be the key to encourage the participants to encounter new words or expressions. The results showed that these four participants were successful in using repetition priming even though their scores varied.

영어출력능력을 위한 어휘의 생산적 학습:

When learning English as a foreign language, receptive learning tends to come first, followed by the practical application of productive learning. However, learners of a foreign language should be exposed to both receptive learning and productive learning simultaneously. Productive learning processes should not be used later than receptive learning. This study explores whether productive use of word combinations is more effective than input-based receptive learning. For the experiment, a productive activity using PowerPoint was designed by modifying an existing ‘unscramble’ activity using TED talks material. 82 Korean college students were divided into experimental and control groups, a productive learning group and a receptive learning group. They were taught in 24 class sessions for one semester. These two groups were assessed using three tests (two L1→L2 translation tests in mid-term and final tests, three delayed receptive tests, three output tests), and in open-ended reports from the experimental group students. The results showed that the experimental group outperformed the other group in acquiring word combinations productively. The findings of this study indicate that the students’ productive use of word combinations tends to result in better memorization and the acquisition of productive and receptive vocabulary.

EFL 교실에서 이미지 스키마의 활용 재고

류도형 ( Ryu Do-hyung ) 한국현대영어영문학회 2021 현대영어영문학 Vol.65 No.2

The purpose of this paper is to critically comment on the effective use of image schema in the EFL classroom, and to suggest an alternative way to teach polysemous words and grammatical relations. This study is based on literature review research. Currently, most literature relevant to the use of image schemas in the EFL classroom indicates that the use of pictorial or graphic representations of image schemas successfully helps low intermediate EFL college students to understand polysemous words and grammatical relations. However, considering that this imposes a learning burden and is time consuming, the argument cannot be supported. The relevant theoretical literature has been reviewed in terms of the definition of image schemas and the relationship between image schemas and language acquisition. This says that image schema is an abstract concept, not an image. Considering that image schemas are embodied prelinguistic structures, it is known that image schemas start very early and that they are already acquired. The findings of the paper implicitly point out that teaching image schemas is not necessary in the EFL classroom and that context-dependent approaches may be enough to teach polysemous words and grammatical relations.

Crack-free joining of $Si_3N_4\;and\;Al_2O_3$ using 15 layers has been achieved by a unique approach introducing Sialon polytypoids as a functionally graded materials (FGMs) bonding layer. In the past, hot press sintering of multilayered FGMs with 20 layers of thickness $500{\mu}m$ each has been fabricated successfully. In this study, the number of layers for FGM was reduced to 15 layers from 20 layers for optimization. For fabrication, model was hot pressed at 38 MPa while heating up to $1700^{\circ}$, and it was cooled at $2^{\circ}$/min to minimize residual stress during sintering. Initially, FGM with 15 layers had cracks near 90 wt.% 12H / 10 wt.% $Al_2O_3$ and 90 wt.% 12H/10 wt.% $Si_3N_4$ layers. To solve this problem, FEM (finite element method) program based on the maximum tensile stress theory was applied to design optimized FGM layers of crack free joint. The sample is 3-dimensional cylindrical shape where this has been transformed to 2-dimensional axisymmetric mode. Based on the simulation, crack-free FGM sample was obtained by designing axial, hoop and radial stresses less than tensile strength values across all the layers of FGM. Therefore, we were able to predict and prevent the damage by calculating its thermal stress using its elastic modulus and coefficient of thermal expansion. Such analyses are especially useful for FGM samples where the residual stresses are very difficult to measure experimentally.
