Japanese Sign Language Recognition by Combining Joint Skeleton-Based Handcrafted and Pixel-Based Deep Learning Features with Machine Learning Classification

Sign language recognition is vital for enhancing communication accessibility among the Deaf and hard-of-hearing communities.In Japan,approximately 360,000 individualswith hearing and speech disabilities rely on Japanese Sign Language(JSL)for communication.However,existing JSL recognition systems have faced significant performance limitations due to inherent complexities.In response to these challenges,we present a novel JSL recognition system that employs a strategic fusion approach,combining joint skeleton-based handcrafted features and pixel-based deep learning features.Our system incorporates two distinct streams:the first stream extracts crucial handcrafted features,emphasizing the capture of hand and body movements within JSL gestures.Simultaneously,a deep learning-based transfer learning stream captures hierarchical representations of JSL gestures in the second stream.Then,we concatenated the critical information of the first stream and the hierarchy of the second stream features to produce the multiple levels of the fusion features,aiming to create a comprehensive representation of the JSL gestures.After reducing the dimensionality of the feature,a feature selection approach and a kernel-based support vector machine(SVM)were used for the classification.To assess the effectiveness of our approach,we conducted extensive experiments on our Lab JSL dataset and a publicly available Arabic sign language(ArSL)dataset.Our results unequivocally demonstrate that our fusion approach significantly enhances JSL recognition accuracy and robustness compared to individual feature sets or traditional recognition methods.

Researching Creativity in Second Language Acquisition:Book Review

In the realm of psychology and language acquisition,the exploration of“individual differences”-encompassing attributes such as personality traits,motivation,and language aptitude-has long been a focal point of scholarly investigation.Within this sphere,the book“Researching Creativity in Second Language Acquisition”by Ashleigh Pipes offers a fresh perspective on the role of creativity as a significant individual difference in Second Language Acquisition(SLA).Positioned against the backdrop of extensive empirical research on individual differences,this book stands out by focusing on the often overlooked aspect of creativity,which Pipes argues,holds paramount importance in SLA.

A Brief Study of Second Language Learning Strategies From the Perspective of Error Analysis

Language teaching is not a one-way process.It interacts with language learning in an extremely intricate way.To improve language teaching,we need to take the process of language learning into account.This paper tries to explore and understand what strategies the second language learners consciously or subconsciously adopt during their language learning process through the analyses of the linguistic errors they commit,so as to provide some insights into language teaching practice.

Research on the Application of Chinese-Style Songs in the Field of Chinese Second Language Teaching

In recent years,traditional Chinese culture has been continuously revived,integrated into the times and entered people’s daily lives.Chinese-style songs,as a combination of traditional cultural connotations and emerging song forms,have gradually emerged on the music stage in China and even around the world.In the field of teaching Chinese as a second language,the research on teaching Chinese songs has received increasing attention.This article combines the theory of the association between music and language to summarize the research results of Chinese-style songs and their application in the field of teaching Chinese as a second language in the past 30 years.The current research problems are discussed,and suggestions are proposed in order to provide some reference value for teaching Chinese as a second language.

Promoting the Learners’Motivation in Learning Chinese as a Second Language:From Demotivation to Motivational Strategies

Motivation is a key factor that influences the outcome of second language(L2)learning.Chinese as a second language(CSL)learners,however,may experience demotivation in their Chinese learning process which will,more often than not,reduce their learning interest and eventually affect their learning effect,therefore,it is necessary to enhance the learners’motivation level.This article first reviews the research literature in motivation in general,then discusses the CSL learners’demotivation in their Chinses learning process studying in China.Finally,it introduces motivational strategies to activate CSL learners’motivation in learning Chinese.

A Study on Second Language Vocabulary Acquisition Under the Categorization Theory

In cognitive linguistics,debates on the status and functions of categorization have been a heated issue.In semantics and second language acquisition,scholars have discussed and achieved vocabulary acquisition from different perspectives and academic levels.Vocabulary learning exerts a fundamental role in second language vocabulary acquisition(SLVA),and it is closely related to learners’cognitive competence.However,studies on second language vocabulary acquisition under the categorization theory in cognitive linguistics have received less attention from linguists when compared with other studies.This paper employs two representative dimensions,the basic-level effect and the prototype effect,under the categorization theory to further delve into the implications on second language vocabulary acquisition.This article first provides a comprehensive introduction to the nature and the approaches of the categorization theory,and then analyzes the relations and implications for second language vocabulary acquisition under the categorization theory from the perspective of the basic-level and the prototype effects.The research results showed that the basic-level effect on SLVA is mainly on the classification of word categories distinguished from the superordinate and subordinate categories,while the prototype effect is more on understanding the complexity and use of word meaning.

Student Evaluations as Effective Indicators of Learning Outcomes:Evidence from Japanese University Students in English Language Courses

The term"student learning outcomes"refers to the knowledge, skills, and abilitiesthat students achieve during a course, and is typically assessed based on student evaluations conducted at the end of the semester. Previous studies in this area have investigated the effects of instructional quality and academic demands separately and have been limited primarily to examining findings using student samples fromthe United States. With Japanese college students' perceptions of self-improvementin English language courses as the dependent variable, the present study directly tests the hypothesis that students who perceive instructional quality to be higher, andcourse demands to be greater, also estimate higher levels of self-improvement in English language skills. The analysis provides strong support for this hypothesis.Higher ratings of instruction and academic demands have already beenshown to increase levels of student learning(Greimel-Fuhrmann and Geyer 2003;Nois and Hudson 2006; Mc Fadden and Dart 1992). The present study is the first toprovide direct evidence of the relative importance of student evaluations ofinstructional quality and academic demands as predictors of student learning and thefirst ever to do so with a sample of Japanese college students enrolled in a required English as a foreign language course. Our hypothesis is that Japanese students whoperceive instructional quality to be higher, and course demands to be greater,estimate higher levels of self-improvement in English language skills. Thus we test Japanese students' attitudes toward instructional quality and course demands asindependent variables predicting their perceptions of self-improvement in English language courses. The research focuses on Japanese students' improvement in English language skills because English education in Japan is an arena in which thedebate over limited English proficiency rages on, and because other research suggests reconsideration of English education in light of the demands of the rapidly expanding global era(Amaki 2008).

A Study on Strategy and Method of Acquisition of the Second Foreign Language

With the successful hosting of the Beijing Olympic Games in 2008 and the World Exposition Shanghai China 2010,English,next to our mother tongue,has become the most important language in China.Therefore,learning English well is very important for most Chinese people.However,learning a foreign language well is not easy.We have to master several learning strategies and methods to learn it successfully.This paper will help all the foreign language learners to find the effective way in learning the second foreign languge.The paper mainly talks about two aspects:improving the abilities in listening,speaking and reading in order to communicate well;developing the ability of writing in English and perfecting the function of social communication.It gives out the concrete methods in listening,speaking,reading,writing,and translating.The authors hope that the paper would be helpful in assisting the foreign language learners to learn and master the second foreign language.

Idioms,Collocations,Formulaic Phrases and Second Language Acquisition

Idioms,collocations,and formulaic phrases are three factors playing the important role in the second language acquisition(SLA).This essay firstly deals with the definitions of these concepts,then it illustrates the importance of them to SLA on two perspectives—idioms,collocations,and formulaic phrases respectively and they regarded as a whole.Therefore,in this way,the essay may lead to the answer the question“How are idioms,collocations,and formulaic phrases important to SLA?”

Age Factor in Second Language Acquisition

In the second language acquisition, the study focus of linguistics is the influence of age factors which has always been considered as one of the most controversial issues. Some experts hold that the younger the better and would get good competence to learn language well, meanwhile others believe that adult have more strong motivation and competence.Based on the Brain Plasticity Theory and the Critical Period Hypothesis, and the intention of this thesis is to reveal such a hypothesis that the younger the learner who starts to learn a second language, the greater performance that he will achieve like a native does, through the comparative research between children and adults. The subjects are 100 Chinese learners who begin learning at different levels and ages. According to the results of integrated scores and a collection of the data in the questionnaire, an analysis show that the results acquired would be consistent with the hypothesis.The intention of this research is not only to argue which is better, earlier or later, but also an trial, through investigation and study, to provide some insights and suggestion to the existent issues, especially the children second language education and college English study in China.

Negative Transfer in Second Language Acquisition

Negative transfer is the basic term we need to master in second language acquisition.This paper tries to analyze negative transfer of Chinese from the aspects of lexis,syntax and pragmatics.Besides,it provides suggestions on how to minimize negative transfer in second language teaching.

The Correlation between L1A and Second Language Teaching

L1A(first language acquisition)is expected to shed light on the L2(second language)teaching.However,how far L1A correlates with second language teaching is an argument that never ends.Hence,the hypotheses on L1A and its connection with L2 Teaching are analyzed,along with a discussion on the relationship between L1A,L2A and L2 Teaching.The limitation of L1A to L2T is elaborated from the aspect of literacy,age and time distinction.

Evaluation of Email Effectiveness in ESL Writing Classroom Guided by Second Language Acquisition Theory

The wide application of internet technology has provided the possibility to study and research new writing concepts and teaching modes in the classroom of English as a Second Language(ESL).In this trend,using email to assist English writing class has gained much attention in this field.This paper discusses the evaluation of email effectiveness with the implication of the Second Language Acquisition(SLA) theory.The result shows that the email assisted English writing class is a very salient method though it had its limitation somehow.

On the Role of Noticing in Second Language Acquisition and Learning

Apparent discrepancy exists between Schmidt's Noticing Hypothesis and Krashen's Input Hypothesis. Whilst Krashen highlights the importance of comprehensible input and asserts that language is acquired unconciously, the notion of conscious learning has gained wide support from Schmidt and other researchers. They argue that noticing enhances second language development as one crucial level of consciousness. By reviewing the theoretical constructs that underlie the role of noticing, this paper aims to justify the role of noticing as one crucial level of consciousness in enhancing second language learning.

Pedagogical Implications for Second Language Acquisition

Second language acquisition is influenced by various factors,among which age and environment are two major factors.Language acquisition and language learning are two different concepts,but they are correlated and they interact with each other.Therefore,in second language teaching teachers and researchers should follow the rules of second language acquisition and second language learning and analyze the factors such as learners' possible errors,motivation,learning strategies and personalities.

Language Awareness and Second Language Learning:A Critical Review

Beginning with the history,definition and levels of Language Awareness,this paper reviewed and analyzed two views:1) Language awareness is one necessary condition in language learning,or 2) Language learning can be achieved without Language Awareness.It pointed out the problems existing in these studies:1) Limitations in sample choice,concerning the adult beginning learners instead of the learners in different learning stages;2) Limitations in methodology,preferring cross-sectional researches to longitudinal case studies;and 3) Limitations in material choice,focusing on "word" level rather than other levels or aspects of language learning.This paper argued that language awareness is dynamic in the whole process of language learning.
