Students always feel that linear algebra is abstract, boring, and difficult to understand. For the teaching of linear algebra, the instructional design of linear algebra that combining the geometry intuition and practical application is proposed to help students understand the abstract knowledge. As an example in our teaching process, the geometric interpretation of matrix, similar matrices, eigenvalues and eigenvectors are given in turn. This teaching method aims to help students shift perception from visual to abstract and thus improve the teaching efficiency of linear algebra. The practical application of eigenvalue in image compression, i.e. Karhunen-Loeve transform, is presented. It is advantages to promote students' motivation in learning and cultivate their abilities in using mathematics to solve practical problems.","PeriodicalId":161426,"journal":{"name":"Proceedings of the 11th International Conference on Education Technology and Computers","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126809789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Summarization of software artifacts is one of application of natural language processing techniques to help the developers or testers. Summarization tools and techniques have been applied to many software artifacts in the past like source code, discussions and bug reports. In this paper, we present a systematic literature review of the natural language processing techniques applied for the summarization of bug reports. Bug reports are very important for development process because these have valuable knowledge of the problems and their resolution. By summarizing bug reports, a lot of developer's time can be saved during bug triaging when developers are looking for the similar problems from the past. Bug report summarization is done by various methods and techniques and it have helped the developer to save their time and better understanding of the problem at hand. This survey of the past techniques used for the summarization of bug reports will provide useful and wide background knowledge of this research field to the future researchers.","PeriodicalId":161426,"journal":{"name":"Proceedings of the 11th International Conference on Education Technology and Computers","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127129839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An example of a learning disability is Down Syndrome (DS). Children with DS are usually unable to follow the traditional educational systems. As a result, these children need tailored methods and techniques that adapt to their learning styles. Therefore, new educational tools are being developed that allow Down Syndrome Children (DSC) to sharpen their intellectual capacities in a better way. In this research, we implemented and modified two literature-based mobile tools that could aid in acquiring mathematics and linguistic skills oriented towards DSC. We performed a quasi-experimentation to test the improvements in mathematics and language skills in a group of children with DS. Moreover, we found that measuring the response time of children with disabilities is a complex task; and the continuous assistance from a tutor was also found to be necessary. Despite the difficulties encountered, such as distraction from the children because of being curious to interact with a technological tool, the results show that it is possible to increment the mathematical and language skills in a group of DSC by using an Information and Communication Technology (ICT) based tool in contrast with a classical teaching methodology without ICT tools.","PeriodicalId":161426,"journal":{"name":"Proceedings of the 11th International Conference on Education Technology and Computers","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132022056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oral Corrective Feedback (OCF) is generally time-consuming and labor-intensive work for teachers. The use of ASR (Automatic Speech Recognition) in SFL education has drawn attention from both teachers and learners to increase the learning effect and efficiency. We designed and integrated Quantitative OCF using Google Cloud Speech-to-Text as a part of the oral assessment using an LMS (Learning Management System) for Japanese SFL courses. The level of learners is a starter's level without any prerequisite knowledge of Japanese language. Preliminary experiments using a total of 214 audio datasets by non-native speakers exhibited that 37.4% of the datasets were recognized properly as Japanese sentences. However, as the remainder of the datasets contains erroneous utterances, characteristics of intonation, or noise, ASR successfully detected word-based errors with high accuracy (82.4%) but low precision (28.1%). Oral assessment employing ASR is highly promising as a complementary system for teachers on partially automating the assessment of audio data from learners with evidence and priority orders as well as significantly reducing teachers' scoring workload and time spent on the most problematic part of the students' speech. While our implementation still requires teachers to double-check, such overhead is small and affordable.","PeriodicalId":161426,"journal":{"name":"Proceedings of the 11th International Conference on Education Technology and Computers","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114799072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
