Liu, Zhen-Jie & Jin, Ming-Hao. (2018). A study of the content validity of reading comprehension tests in NMET II. The Linguistic Association of Korea Journal, 26(4), 103-124. Based on Bachman and Palmer’s (1996) framework of task characteristics, this paper aims to compare the reading comprehension tests of the 2013-2017 National Matriculation English Test II (NMET II) with the requirements of the New Curriculum Standards and Testing Syllabus, in particular, concerning the content validity of the tests in terms of the characteristics of input and expected responses. The implications of this study are discussed for test designers, teachers, and students. The results show that reading comprehension tests from 2013 to 2017 basically meet the requirements of the New Curriculum Standard and Testing Syllabus and have a high content validity. In terms of the characteristics of input, the length, reading speed, and readability of comprehension passages are appropriate for students; however, the distribution of topics and genres in each year is uneven. In terms of the characteristics of expected responses, the wordings of questions and the design of question items are reasonable. However, the response type is mainly restricted to selected response questions (multiple-choice), and the measure of reading skills coverage is unbalanced.

( Ming-hao Jin ),( Mei-xian Zheng ) 대한언어학회 2020 언어학 Vol.28 No.3

Based on Bachman and Palmer’s (1996) Framework of Task Characteristics and Li’s (1996) Test Point Validity Theory, this paper aims to analyze the test point quality and content validity of grammar gap-filling tests of the 2014-2019 National Matriculation English Test paper II (NMET II), in particular, concerning the content validity of tests in terms of the characteristics of input and expected responses, and test point validity. The results show that the grammar gap-filling tests in the NMET II are all in line with the language knowledge part required in the New Curriculum Standard and the Testing Syllabus and have a relatively high content validity. The test points are evenly distributed and reasonably designed, which can test students' grammar ability under the guidance of discourse with well designed length and reasonable test point validity. However, there are still some problems to be improved, such as the lack of ‘man and nature’ and practical essay writing in terms of topic and genre. The readability fluctuated greatly. The expected response type is restricted to limited production. Furthermore, test points designed with discourse level and meaning factor are less examined, and lacking of test points used to measure a higher grammatical ability.

Locative Inversion in Mandarin Chinese

( Ming Hao Jin ) 대한언어학회 2015 언어학 Vol.23 No.4

On the detailed analysis of Mandarin Chinese (MC) locative inversion constructions from the aspect markers of le and zhe, verbs, agent and postverbal NP, this paper attempts to explain EPP and Case realization of locative inversion in MC. It suggested that Cases for PP-subjects may be realized differently from language to language. Unlike other languages, the PP-subjects in MC do not arise from locative inversion like those in English, but are introduced directly by the light verbs EXIST and OCCUR in the subject position which are used to satisfy the Case of EPP. These light verbs EXIST and OCCUR are the Case realization in MC, and DP after V in locative inversion constructions has partitive Case in LF.

Distributed Fusion Filter for Multi-rate Sampling Stochastic Singular Systems with Multiplicative Noises

Hao Jin,Jing Ma,Yun Li,Ming Zhao 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.2

The distributed fusion filtering problem is studied for multi-rate sampling stochastic singular linear systems with multiple sensors and stochastic multiplicative noises. The system is described at the highest sampling rate and different sensors may have different lower sampling rates. The white noise in measurement matrix is introduced to describe the stochastic disturbance. Firstly, based on decomposition in canonical form, the original singular system is transformed into fast and slow two subsystems. For the two reduced-order subsystems, the local filters (LFs) are given based on the “dummy” random variables. The cross-covariance matrices between any two local filtering errors are derived. Further, the distributed fusion filter weighted by matrices (FFWM) is obtained for the original singular system based on the well-known fusion algorithm in the linear minimum variance sense. Simulation example verifies the correctness and feasibility of the proposed algorithm.

Ming Hao Jin,Eunhye Shin,Saera Jin,Hongil Jo,Kang Min Ok,Jongin Hong,Byung-Hyuk Jun,James R. Durrant 한국물리학회 2018 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.73 No.5

Cubic BaTiO3 (C-BT) and tetragonal BaTiO3 (T1-BT) nanoparticles were prepared by a solvothermal method with controlling the Ba/Ti precursor ratio. Triethanolamine was additionally employed in the synthesis to obtain ferroelectric BaTiO3 with improved particle size distribution and tetragonality (T2-BT). The prepared nanoparticles were thoroughly characterized by scanning electron microscopy, transmission electron microscopy, Brunauer-Emmett-Teller analysis, X-ray diffraction, X-ray photoelectron spectroscopy, ultraviolet-visible spectroscopy, photoluminescence, and second-harmonic generation. Importantly, the BaTiO3 nanoparticles were introduced into the scattering layer of dye-sensitized solar cells and T2-BT showed better power conversion eciency than C-BT and T1-BT.

A Study on Chinese-Korean Bilinguals` Language of Thought in English Writing

( Ming Hao Jin ),( Byoung Man Jeon ) 글로벌영어교육학회(구 호남영어교육학회) 2012 Studies in English education Vol.17 No.1

This paper attempts to examine language of thought and code switches among three languages the Chinese-Korean bilingual English learners employ in the process of English writing. 24 Korean dominant, Chinese-Korean bilinguals of three groups at the different English learning stages were chosen as subjects who were required to complete an English writing task with pictures by the method of ``think aloud`` respectively. Wang and Wen`s (2002) five English writing steps and Wen and Guo`s (1998) classification of language functions in the text output of English writing were used to analyze data. The findings of the study indicate that Chinese-Korean bilingual English learners use Korean and Chinese language of thought largely to help themselves complete English writing task. This study suggests that Chinese-Korean bilinguals have an outstanding ability in switching different linguistic codes and their existing linguistic knowledge is a great asset in learning the third language English.

Content Validity of Language Knowledge Sections of Four National Matriculation English Test Papers in China

Ming-Hao Jin,Byoung-Man Jeon 한국영어어문교육학회 2013 영어어문교육 Vol.19 No.4

This study attempts to analyze the content validity of the language knowledge sections of four National Matriculation English Test (NMET) papers administered in 2012 from the perspective of the New Senior English Curriculum Standards (NSECS) and the 2012 test syllabus in order to see to what extent the language knowledge sections of the NMET meet the requirements of the NSECS and specifications of the test syllabus. The results show that all items of the language knowledge sections of four NMET papers had relatively high content validity with its design corresponding to the requirements of the NSECS and the 2012 test syllabus in terms of basic grammar and grammatical use of vocabulary. However, some deficiencies were found which might affect the content validity of the NMET. Most test items of the language knowledge sections were multiple-choice questions so that the expected responses were limited to selected production responses. It is suggested that limited and extended production responses should be increased in order to improve quality of the language knowledge section. The types of test items should also be diversified to examine test takers' higher level oflanguage knowledge.

A Correlation Study of Chinese English Learners’ Writing Anxiety, Writing Strategies, and Writing Achievements

( Ming-hao Jin ),( Yan Guo ) 대한언어학회 2021 언어학 Vol.29 No.1

This study aims to investigate Chinese English learners’ writing anxiety, and analyzes its correlation with their writing strategies and writing achievements. Two questionnaires, designed by referring to and re-editing Petric and Czarl’s (2003) Writing Strategies Questionnaire and Cheng’s (2004) Second Language Writing Anxiety Inventory, were completed by 90 Chinese senior high school students in Yanji, China. SPSS 24.0 was used to analyze the data and produce descriptive statistics, paired sample T-tests, and Pearson correlation coefficient analysis. The result shows that students have a moderate degree of anxiety. High anxiety students experience the highest cognitive anxiety, and low anxiety students experience the highest physical anxiety. English learners’ writing anxiety shows a significant negative correlation with writing strategies. High anxiety students seldom use English writing strategies, while low anxiety students use them very often in the process of completing a writing task. English learners’ writing anxiety shows a significant negative correlation with writing achievements as well. The higher English learners' writing anxiety is, the lower their writing achievements will be. Thus, English learners should be encouraged and trained to use English writing strategies well to reduce English writing anxiety and improve the level of writing achievements.
