Evaluation of Tennis Teaching Effect Using Optimized DL Model with Cloud Computing System
Статья научная
Evidence from psychology and behaviour therapy shows that engaging in sports activities at home might help alleviate stress and depression during COVID-19 lockdown periods. A clever virtual coach that provides table tennis instruction at a low cost without invading privacy might be a great way to maintain a healthy lifestyle without leaving the house. In this article, we look at creating the second main constituent of the virtual-coach table tennis shadow-play training scheme: an evaluation system for the effectiveness of the forehand stroke. This research was carried out to demonstrate the efficacy of the suggested bidirectional long-short-term memory (BLSTM) model in assessing the table tennis forehand shadow-play sensory data supplied by the authors in comparison with LSTM time-series investigation approaches. Information was collected by tracking the rackets of 16 players as they performed forehand strokes and assigning assessment ratings to each stroke based on the input of three instructors. The scientists looked at how the hyperparameter values, which are chosen via an optimisation approach, affected the behaviour of DL models. The adaptive learning differential approach has been introduced to enhance the functionality of the standard dragonfly algorithm. Optimal BLSTM settings are selected with the help of the enhanced dragonfly algorithm (IDFOA). The experimental findings of this study indicate that the BLSTM-IDFOA is the most effective regression approach currently available.

Examining Chen and Starosta's Model of Intercultural Sensitivity in the Taiwanese Cultural Context
Статья научная
The main purpose of this study was to empirically examine Chen and Starosta's Model of Intercultural Sensitivity and reproduce a valid scale in the Taiwanese cultural context, using both exploratory and confirmatory factor analyses. Results indicated that Chen and Starosta's five-factor model of intercultural sensitivity (IS) did not fit the Taiwanese cultural context. Instead, a four-factor model of IS was created using an exploratory factor analysis. The four factors were based on the 13 items of 24-item Intercultural Sensitivity Scale (ISS) formulated by Chen and Starosta. The reliability coefficient was .801, demonstrating high internal consistency. A confirmatory factor analysis was performed again to determine the construct validity of the alternative model of IS. Since cultural differences may influence the factor structure of a test, using both EFA and CFA can methodologically provide a meaningful explanation for replication studies. This study proposes an alternative model of the Intercultural Sensitivity Scale that is a better fit with Taiwanese culture by reinterpreting Chen and Starosta's ISS.

Examining Mindfulness in Education
Статья научная
Despite the availability of numerous learning opportunities ranging from face-to-face to computer-based learning, there is need for better understanding of how to support the development of cognitive skills in students. Research has shown that cultivation of mindfulness skills help to develop cognitive skills such as retention, thinking, problem solving, and emotional balance. However, there is only limited research on the effect of mindfulness training in educational settings. We examined cognitive abilities of university students as identified in Bloom's taxonomy and mindfulness skills during a single traditional face-to-face class room session. We hypothesized that mindfulness is a specific cognitive ability that supports the development of other cognitive skills. This pilot study included 148 students from undergraduate and postgraduate programs at two universities in Sri Lanka. The study assessed cognitive abilities, including retention, thinking, out-of-the-box thinking, note-taking and mindfulness at the end of a one-hour lecture. The results showed that students' self-reported mindfulness following a lecture was significantly lower than other cognitive abilities. These results suggest conducting a more formal controlled experiment to investigate the effect of mindfulness training in education.

Experimental Analysis of SPF Based Secure Web Application
Статья научная
In this paper we will propose model driven software development and Security Performance Framework (SPF) Model to maintain the balance between security and performance for web applications. We propose that all security in a Trusted Operating System is not necessary. Some non-essential security checks can be skipped to increase system performance. These non essential security checks can be identified in any web application. For implementation of this Security Performance framework based trusted operating system, we propose object oriented based Code generation through forward engineering. This involves generating source code of web application from one or more Object oriented Rational Rose model. The novel integration of security engineering with model-driven software expansion approach has varied advantages. To maintain security in various applications like Ecommerce, Banking, Marketplace services, Advertising, Auctions, Comparison shopping, Mobile commerce Payment, Ticketing, Online insurance policy management, we have to use high secured operating systems. In this regard a number of trusted operating systems like Argus, Trusted Solaris, and Virtual Vault have been developed by various companies to handle the increasing need of security. Due to high security reason these operating systems are being used in defense. But still these secure operating systems have limited scope in commercial sector due to lower performance; actually this security will come at a cost. This paper analyzes UML-based software development solutions for SPF to manage the security, performance and modeling for web applications.

Explainable Fake News Detection Based on BERT and SHAP Applied to COVID-19
Статья научная
Fake news detection has become a significant research top in natural language processing. Since the outbreak of the covid-19 epidemic, a large amount of fake news about covid-19 has spread on social media, making the detection of fake news a challenging task. Applying deep learning models may improve predictions. However, their lack of explainability poses a challenge to their widespread adoption and use in practical applications. This work aims to design a deep learning framework for accurate and explainable prediction of covid-19 fake news. First, we choose BiLSTM as the base model and improve the classification performance of the BiLSTM model by incorporating BERT-based distillation. Then, a post-hoc interpretation method SHAP is used to explain the classification results of the model to improve the transparency of the model and increase people's confidence in the practical application. Finally, utilizing visual interpretation methods, such as significance plots, to analyze specific sample classification results for gaining insights into the key terms that influence the model’s decisions. Ablation experiments demonstrated the reliability of the explainable method.

Explicit Instruction-based Methodology for Teaching Introductory Computer Programming
Статья научная
Non-computing students often encounter greater challenges in programming courses compared to their computing counterparts, primarily stemming from a lack of motivation in the subject. Motivation plays a pivotal role in the success of introductory programming (IP) modules, with intrinsically and extrinsically motivated students exhibiting greater enjoyment and engagement in learning activities. While numerous studies have attempted to enhance motivation in IP modules, most have focused on computing students which is influenced lar gely by the constructivist theory. This paper addresses this gap by proposing a cognitive-based teaching framework aimed at bolstering motivation among non-computing students. The proposed approach employs the Explicit Instruction paradigm, where the instructor first designs learning strategies and provides students with detailed explanations, demonstrations, examples, and non-examples. This enables the students to apply the strategies in groups, practice with feedback, and finally individually. The effectiveness of this approach was assessed using first-year students at two universities, one in South Africa and the other in Cameroon. We collected student motivation data using a quantitative questionnaire post-experiment. The results indicate that the proposed teaching method had a positive impact on participant motivation in terms of attendance, perceived relevance, confidence, and satisfaction. However, the specific degree of improvement varied among the participants.

A group of researchers and developers from Colombia and Mexico have recognised that the development of state-of-the-art Extended Reality software, a key technology for the Metaverse, has great potential to improve teaching-learning processes in educational institutions. However, the development process does not take into account accessibility, universal design and inclusion, especially for the deaf student community. An extended reality model is proposed for the creation of this type of software as a tool to support access to knowledge, based on information gathering, requirements analysis, user-centred design and video game programming, including the ludic and didactic. The aim is to minimise the barriers that limit the learning of programming logic by students with hearing disabilities through the use of new technologies, creating spaces in virtual worlds that are understandable, usable and practical in conditions of safety, comfort and as much autonomy as possible. To validate the model, a mixed reality software prototype was designed and programmed to train students in programming logic, both deaf and hearing. User and heuristic tests were carried out, showing how immersion can improve knowledge acquisition processes and develop skills in higher education students.
