Immersive Virtual Reality Teaching in Colleges and Universities Based on Vision Sensors

With the progress of society and the development of economy, people pay more and more attention to education, and traditional teaching methods are gradually unable to meet the modern teaching system. As a leader in modern information technology, virtual reality technology has developed rapidly in recent years, and virtual reality technology has also been introduced into many fields, such as teaching. Based on the immersive and extended characteristics of virtual reality, this paper proposes a virtual reality active visual interaction method based on the visual sensor. Based on virtual teaching, after 3 months of learning, the average, standard deviation, and average standard error of the experimental group’s performance are higher than those of the control group. Compared with the control group, the experimental group’s performance has increased by 8.25%. The difference is statistically significant. Learning significance ( P < 0.05 ), immersive virtual reality teaching has played a significant role in the effect, which can greatly improve the cognitive experience of students and achieve a good learning experience and effect.

Great Tits Learn Odors and Colors Equally Well, and Show No Predisposition for Herbivore-Induced Plant Volatiles

Ability to efficiently localize productive foraging habitat is crucial for nesting success of insectivorous birds. Some bird species can use olfaction to identify caterpillar-infested trees by detection of herbivore induced plant volatiles (HIPVs), but these cues probably need to be learned. So far, we know very little about the process of olfactory learning in birds, whether insectivorous species have a predisposition for detecting and learning HIPVs, due to the high ecological significance of these odors, and how olfaction is integrated with vision in making foraging decisions. In a standardized setup, we tested whether 35 wild-caught great tits (Parus major) show any preference for widely abundant HIPVs compared to neutral (non-induced) plant odors, how fast they learn to associate olfactory, visual and multimodal foraging cues with food, and whether the olfactory preferences and learning speed were influenced by bird sex or habitat (urban or rural). We also tested how fast birds switch to a new cue of the same modality. Great tits showed no initial preference for HIPVs compared to neutral odors, and they learned all olfactory cues at a similar pace, except for methyl salicylate (MeSA), which they learned more slowly. We also found no differences in learning speeds between visual, olfactory and multimodal foraging cues, but birds learned the second cue they were offered faster than the first one. Bird sex or habitat had no effect on learning speed or olfactory preference, but urban birds tended to learn visual cues more slowly. We conclude that insectivorous birds utilize olfactory and visual cues with similar efficiency in foraging, and that they probably don‘t have any special predisposition toward the tested HIPVs. These results confirm that great tits are flexible foragers with good learning abilities.

Influence of Teaching Reading Islamic Narrative Stories toward Students’ Social Behavior

In this millennium era, Indonesia faced moral crisis within the school or outside the school. They are accustomed to do bad behavior due to spiritual lack. Spiritual crisis happened because they were not given enough lessons about religion. However, teachers must provide good learning materials, so that the students can change their behavior. Even when teachers/lecturers teach English they must include religious knowledge in their teachings. Such as reading moral stories, giving good advices to students, telling about prophet stories, etc. Reading or telling story can affect moral, as the study held by Dr. Kang Lee and Colleagues that was recently published in the article ”Can Classic Moral Stories Promote Honesty in Children”.

The Use of YouTube As A Medium for Teaching English Writing Skill During Covid-19 Pandemic

A popular video sharing site, YouTube, could be used as an alternative teaching medium in online learning activities during the COVID-19 pandemic. It is useful to help students to keep on learning and get materials well in the difficult circumstance caused by the pandemic. This study aims to describe how Youtube is used as a learning medium in English teaching, especially the writing skill at MTs Ma'aarif NU 01 Kemranjen during the COVID-19 pandemic. This study uses a qualitative approach. Data are collected through the triangulation of interview, observation, and documentation. The data are then analysed by applying Miles and Huberman’s (1994) model of data reduction, data display, and verification. The results of this study reveal that Youtube is seen to be a good learning medium to cope with the learning difficulties in the unprecedented Covid-19 crisis. The asynchronous nature of the Youtube videos enabled students to repeat the video as much as they want to. The implementation of Youtube in online learning was done in three stages: 1) preparation, the teacher makes and uploads the videos; 2) implementation, the teacher shares the link and provides brief explanation on WhatsApp; and 3) evaluation, the teacher gives quizzes to ensure that the materials are well-received. Meanwhile, the obstacles in the implementation are poor Intenet network, insufficient facilities, and unmotivated students. The pedagogical implication from this study is that Youtube is a good fit for online learning, it is highly recommended for teaching during the pandemic.

In order to improve the planning ability of the badminton backcourt stroke line, this study designs a badminton backcourt stroke line planning method based on deep learning. Firstly, the trajectory adaptive learning method of motion primitives is used to design the hitting line nodes and path space, so as to construct the shortest distributed grid structure model of the hitting line. Then, the constraint parameters of hitting route planning are analyzed, and then the hitting position and player posture are controlled according to node positioning and shortest path optimization deployment. Finally, the adaptive optimization of the route planning process is realized by combining the deep learning method. The simulation results show that this method has good learning control ability and good convergence performance and improves the reliability of badminton backcourt hitting line planning.

Evaluating the learning and performance characteristics of self-organizing systems with different task features

Self-organizing systems (SOS) are developed to perform complex tasks in unforeseen situations with adaptability. Predefining rules for self-organizing agents can be challenging, especially in tasks with high complexity and changing environments. Our previous work has introduced a multiagent reinforcement learning (RL) model as a design approach to solving the rule generation problem of SOS. A deep multiagent RL algorithm was devised to train agents to acquire the task and self-organizing knowledge. However, the simulation was based on one specific task environment. Sensitivity of SOS to reward functions and systematic evaluation of SOS designed with multiagent RL remain an issue. In this paper, we introduced a rotation reward function to regulate agent behaviors during training and tested different weights of such reward on SOS performance in two case studies: box-pushing and T-shape assembly. Additionally, we proposed three metrics to evaluate the SOS: learning stability, quality of learned knowledge, and scalability. Results show that depending on the type of tasks; designers may choose appropriate weights of rotation reward to obtain the full potential of agents’ learning capability. Good learning stability and quality of knowledge can be achieved with an optimal range of team sizes. Scaling up to larger team sizes has better performance than scaling downwards.
