Pronunciation variations and context-dependent model to improve ASR performance for dyslexic children’s read speech

Focusing on the key element for an ASR-based application for dyslexic children reading isolated words in Bahasa Melayu, this paper can be an evidence of the need to have a carefully designed acoustic model for a satisfying recognition accuracy of 79.17% on test dataset. Pronunciation variations and context-dependent model are two main components of such acoustic model. This model adopts the most frequent errors in reading selected vocabulary, which are obtained from primary data collection and analysis.The analysis gives the most frequent spelling and reading errors as vowel substitution with over 20% of total errors made

Responsible research and innovation in science education: insights from evaluating the impact of using digital media and arts-based methods on RRI values

The European Commission policy approach of Responsible Research and Innovation (RRI) is gaining momentum in European research planning and development as a strategy to align scientific and technological progress with socially desirable and acceptable ends. One of the RRI agendas is science education, aiming to foster future generations' acquisition of skills and values needed to engage in society responsibly. To this end, it is argued that RRI-based science education can benefit from more interdisciplinary methods such as those based on arts and digital technologies. However, the evidence existing on the impact of science education activities using digital media and arts-based methods on RRI values remains underexplored. This article comparatively reviews previous evidence on the evaluation of these activities, from primary to higher education, to examine whether and how RRI-related learning outcomes are evaluated and how these activities impact on students' learning. Forty academic publications were selected and its content analysed according to five RRI values: creative and critical thinking, engagement, inclusiveness, gender equality and integration of ethical issues. When evaluating the impact of digital and arts-based methods in science education activities, creative and critical thinking, engagement and partly inclusiveness are the RRI values mainly addressed. In contrast, gender equality and ethics integration are neglected. Digital-based methods seem to be more focused on students' questioning and inquiry skills, whereas those using arts often examine imagination, curiosity and autonomy. Differences in the evaluation focus between studies on digital media and those on arts partly explain differences in their impact on RRI values, but also result in non-documented outcomes and undermine their potential. Further developments in interdisciplinary approaches to science education following the RRI policy agenda should reinforce the design of the activities as well as procedural aspects of the evaluation research

Design and analysis of a database to evaluate children’s reading aloud performance

To evaluate the reading performance of children, human assessment is usually involved, where a teacher or tutor has to take time to individually estimate the performance in terms of fluency (speed, accuracy and expression). Automatic estimation of reading ability can be an important alternative or complement to the usual methods, and can improve other applications such as e-learning. Techniques must be developed to analyse audio recordings of read utterances by children and detect the deviations from the intended correct reading i.e. disfluencies. For that goal, a database of 284 European Portuguese children from 6 to 10 years old (1st–4th grades) reading aloud amounting to 20 h was collected in private and public Portuguese schools. This paper describes the design of the reading tasks as well as the data collection procedure. The presence of different types of disfluencies is analysed as well as reading performance compared to known curricular goals.info:eu-repo/semantics/acceptedVersio

The development and evaluation of software for teaching reading at primary level

This research is an exploratory study and concerns the effectiveness of specific design features in talking book software. Children need to acquire a variety of skills and strategies to become competent readers and these are commonly taught together in the context of meaningful text. Talking book software, replicating real books with additional features such as sound, has the potential to complement this approach. Common features of such software include word pronunciations, hearing sentences read aloud and page turning facilities. These features could facilitate the scaffolding of reading development. The strengths and weaknesses of commercial software were identified through a pilot study. A survey of practitioners was also conducted to investigate how such software is being used in the classroom and whether talking hooks could be improved. The outcomes of these studies together with a review of the literature were used to inform an innovative design that was implemented. In addition to common features, the implementation also included sub-syllabic word pronunciations, hints to encourage independent word identification and activities to reinforce specific reading skills. Two versions of the software were compared using a combination of qualitative and quantitative methodologies including word recognition measures, interviews, observations and case studies. One software version incorporated commonly available features only and the other was a full implementation of the innovative design. Each version of the software was used daily for a period of four weeks by 16 children, aged 6 to 7 years, in the naturalistic environment of their classrooms. The findings of the study were complex due to variations in learner preferences and reading abilities. Nevertheless, it seems that electronic books can complement teaching approaches in infant classrooms and can positively affect both cognitive and affective learning outcomes. It is evident that children of lower reading ability can benefit from common features alone, such as word pronunciations. Those children using the enhanced software who had already acquired a limited sight vocabulary may benefit from additional features such as reinforcement activities. However, these features were not perceived as being fun by the children in this study. Rather, they were seen as educational tasks. The children who had made the greatest progress in reading development prior to the study made more use of the complex features such as hints to assist them in the decoding of unknown words. This study provided evidence to support the theories of scaffolding and the benefits that can be achieved by aiding learners in the zone of proximal development

Musical linguistics: How music and artistic creativity when delivered as a linguistic practice, help students master academic skills in English language arts

This Masters project consists of two elements: 1) an integrated after-school program to improve student English language reading and academic outcomes for third graders\u27 vocabulary development by incorporating music, artistic creativity and linguistics; 2) a pilot sample curriculum that demonstrates the approach for building student comprehension through musical theater and Science, Technology, Engineering, and Mathematics (STEM) content experiences. Called Water Buddy , this is an after-school program uses singing, dancing, writing, and play to build reading and vocabulary skills. The goal is to improve learner academic outcomes by mastering the elemental building blocks of words, letters, symbols by making memorable the sound units, idioms, print conventions, and concepts that they were previously lacking

It was carried out in order to examine the following questions: • What are the ways in which identification, assessment and teaching processes make provision for students with learning difficulties who are enrolled in a School of the Air? • In what ways do Support Officers Learning Difficulties support these children, their home tutors and their teachers

Hand gesture-based interactive puppetry system to assist storytelling for children

© 2016 The Author(s)Digital techniques have been used to assist narrative and storytelling, especially in many pedagogical practices. With the rapid development of HCI techniques, saturated with digital media in their daily lives, young children, demands more interactive learning methods and meaningful immersive learning experiences. In this paper, we propose a novel hand gesture-based puppetry storytelling system which provides a more intuitive and natural human computer interaction method for young children to develop narrative ability in virtual story world. Depth motion sensing and hand gestures control technology is utilized in the implementation of user-friendly interaction. Young players could intuitively use hand gestures to manipulate virtual puppet to perform story and interact with different items in virtual environment to assist narration. Based on the result of the evaluation, this novel digital storytelling system shows positive pedagogical functions on children’s narrating ability as well as the competencies of cognitive and motor coordination. The usability of the system is preliminary examined in our test, and the results which showed that young children can benefit from playing with Puppet Narrator
