Classification of Tri Pramana learning activities in virtual reality environment using convolutional neural network

<em><span lang="EN-GB">Tri Pramana</span></em><span lang="EN-GB"> as the local genius of Balinese society, is now adopted in the education system. This adaptation results in a Learning Cycle Model which essentially consists of three classes namely </span><em><span lang="EN-GB">Sabda Pramana</span></em><span lang="EN-GB"> (theoretical study), </span><em><span lang="EN-GB">Pratyaksa Pramana</span></em><span lang="EN-GB"> (direct observation), and </span><em><span lang="EN-GB">Anumana Pramana</span></em><span lang="EN-GB"> (practicum). In learning activities, it is difficult for educators to fully observe individuals to find out the most suitable learning model. Through Virtual Environment Technology, educators can observe students more freely through the recording of students' activities. However, in its implementation, manual analysis requires large resources. Deep Learning approach based on Convolutional Neural Network (CNN) is able to automate this analysis process through the classification ability of the image of the recorded learner activity. To produce a robust CNN model, this research compares four of the most commonly used architectures, namely ResNet-50, MobileNetV2, InceptionV3, and Xception. Each architecture is tuned using a combination of learning rate and batch size. Through a 512 x 512 resolution dataset with 70% training subset (4,541 images), 20% validation (1,296 images), and 10% test (652 images), the best ResNet model is obtained with a learning rate configuration of 1e-3 and batch size 64 with an accuracy of 99.39%, precision of 99.37%, and recall of 99.42%.</span>

Коучинг в управлении развитием образовательной организации в условиях кризиса

The crisis situation, the pandemic, with the closure of the educational space, has stimulated the integration of the virtual environment and digital technology into the educational space and has brought new leadership challenges. We investigated the experience of employees in the educational space (schools with adapted programmes, primary schools and secondary schools) during the pandemic. We found that employees experienced the negative aspect of facing the pandemic requirements for a virtual work environment. They were faced with the challenge of seeking help during the work process. They also had problems with remote work effectiveness, motivation and satisfaction. We were interested in the school leaders' response to work, the role of the leadership in the process of employee adaptation, and how to identify, understand and use the development tool of coaching when working in a virtual environment. A development tool is an aid to the work process, which enhances work performance. The study confirmed that a development-oriented work process depends on a higher utility value of coaching, from a positive employee response to the use of digital technologies in the work process and leaders' support in this. To the extent that employees were more open to using the Internet in the work process, they also reacted more positively to the new working conditions which required shifting online during the pandemic. A more positive response was also present in those where the leader's support was higher. We also detected a more positive response to the work process among employees who expressed an opinion about the higher useful value of coaching during the work process. We found that employees' response to online technologies was quite positive. Employees' response to the virtual work process was positive. Employees were open to the use of online technologies if the role of the employer was supportive. This leads to a better development-oriented work process.

Pilot Study Using Decision Trees to Diagnose the Efficacy of Virtual Offshore Egress Training

For the offshore energy industry, virtual environment technology can enhance conventional training by teaching basic offshore safety protocols such as onboard familiarization and emergency evacuation. Virtual environments have the added benefit of being used to investigate the impact of different training approaches on competence. This pilot study uses decision tree modeling to examine the efficacy of two pedagogical approaches, simulation-based mastery learning (SBML) and lecture-based training (LBT), in a virtual environment. Decision trees are an inductive reasoning approach that can be used to identify learners’ egress strategies in offshore emergencies after training. The efficacy of the virtual training is evaluated in three ways: 1) analyzing participants’ performance scores in test scenarios; 2) comparing the decision tree depiction of participant's understanding of emergency egress to the intended learning objectives; and 3) comparing the decision strategies developed under a different pedagogical approach. A comparison of the resulting decision trees from the SBML training with trees generated from the LBT showed that the different training methods influenced the participants’ egress strategies. The SBML approach resulted in concise decision trees and better route selection strategies when compared to the LBT training. This pilot study demonstrates the diagnostic capabilities of decision trees as training assessment tools and recommends integrating decision trees into virtual training to better support the learning needs of individuals and deliver adaptive training scenarios.

Helping Others in Virtual Reality Increases Prosocial Self-understanding Among Adolescents.

Reflection on prosocial experiences may be helpful for adolescents highly attentive to their internal states (i.e., high private self-consciousness) to gain prosocial self-knowledge, yet adolescents with low private self-consciousness may not benefit from it. The current study proposed and examined that engaging in helping behavior would be beneficial for those with low private self-consciousness in self-understanding. Two experimental studies using immersive virtual environment technology were conducted to simulate helping situations. A total of 140 middle school students (n = 59, 47.5% female, Mage = 13.98, SD = 0.89, in Study 1; n = 81, 44.4% female, Mage = 15.31, SD = 1.18, in Study 2) completed the experiments. In both studies, adolescents engaging in helping behaviors identified themselves as more prosocial than those who did not engage in helping behaviors. In Study 2, adolescents' positive prosocial self-concept would increase more through engaging in prosocial behavior than by reflecting on past prosocial experiences. Furthermore, adolescents with high private self-consciousness can gain self-understanding both from self-reflection and engaging in prosocial behavior, whereas adolescents with low private self-consciousness benefit only from engaging in prosocial behavior. The findings suggest the need to consider individual differences and adopt appropriate ways of self-understanding when assisting adolescents' prosocial self-formation.

Using a Virtual Workplace Environment to Reduce Implicit Gender Bias

Implicit gender bias has costly and complex consequences for women in the workplace, with many women reporting gender microaggressions which result in them being overlooked or disrespected. We present an online desktop virtual environment that follows the story of a male or female self-avatar from the first-person perspective, who either experiences a positive or negative workplace scenario. The negative scenario included many examples from the taxonomy of gender microaggressions. Participants who experienced negative workplace experiences with a female self-avatar had significantly decreased levels of implicit gender bias compared to those who had a male self-avatar. There was evidence of empathy and perspective taking in the negative condition for the female self-avatar. Experiences of a positive workplace scenario showed no significant decreases in implicit gender bias regardless of self-avatar gender. We discuss the implications of these findings and make recommendations for virtual environment technologies and scenarios with respect to the reduction of implicit biases.

예술 활동을 통한 창의적 코딩에 관한 연구 - 교육 프로그램 사례를 기반으로

Creative coding is a type of computer programming intended to create something expressive rather than functional. If the user does not simply consider efficiency, creative coding can offer multiple ways to produce results that are aesthetically better than just one correct answer. Through the recently expanded virtual reality environment and artificial intelligence technology that imitates human cognition, fundamental research on humans is now more important. Therefore, in the education fields, methods of learning through physical and aesthetic experiences are considered to be important. The meaning of aesthetic education through artistic activities has been introduced in many pedagogical theories. Although one aspect is such that aesthetic sensitivity education can facilitate the psychological adaptation of those being educated when they participate in new educational activities, the importance of learning through aesthetic experience had been highlighted in qualitative learning through experience. This study also examines the evolutionary process of computers as an expressive medium of individuals and software developed for artists and designers. The background and examples of the global coding education movement will be explored, and an example of a creative coding curriculum applied by the researcher in an actual educational setting will be introduced. In particular, in this era where data is becoming the material of creators, creative coding that combines the principles of formative art and computational thinking will provide coding education through aesthetic experiences and a new methodology for art creation. As the main purpose of the convergence of art and technology lies in the development of creativity, creative coding can be used in activities to nurture technology-based creators rather than technology consumers in a meaningful way.

Measuring the Impact of Online Education on Academic Performance Amid COVID-19 with the Moderating Effect of Instructor

The COVID-19 pandemic imposed a new order, another pace for humanity. More than ever, in pandemic times, education is called upon to be unique and to reinvent itself by seeking other possibilities through digital technologies in virtual learning environments. Therefore, it is essential to know the critical factors that affect academic performance during online education. This paper aims to present the effects of student characteristics, time management, and course load on online education. The main aim is to check the impact of online education on academic performance with the mediating effect of burnout and technology and the moderating effect. The data was collected from 313 students in Karachi, Lahore, Islamabad, and Peshawar’s reputable business schools, namely, IoBM, IBA, SZABIST, LUMS, IQRA University, and Institute of Management Sciences, and the data was analysed using PLS-SEM and SPSS. The result suggested that time management, course load, and student characteristics significantly impact online education. The result also indicates that burnout does not mediate the relationship between online education and academic performance. This study also investigated the role of technology and instructors as moderators between online education and academic performance. The result shows that the instructor’s role moderates the relationship, but technology has no impact on moderating this relationship.
