The role of the AI availability and perceived risks on AI adoption and organizational values
Authors: Alzaabi Maryam , Shuhaiber Ahmed
Published: April 2022

Artificial intelligence (AI) is the simulation of human intelligence in various machines which are programmed to think like humans. AI could have many forms, such as Natural Language processing (NLP), expert systems, unsuper-vised learning, content extraction, question answering, image recognition, machine vision, speech to text and machine translation, and Robotics. De-spite the potential of AI technologies, little is known about its adoption by organizations worldwide, and especially in the Arab World and the Middle East. Thus, this research intends to investigate the relationships and the im-pact of the availability of AI technologies and the associated perceived risks on AI adoption in organizations and its perceived organizational values, and also considering two mediating variables: AI replacing humans and AI creat-ing jobs, in one Arab and Gulf country, the UAE. By reviewing the literature and describing the AI applications and services available in UAE, a research model was proposed and tested quantitatively on a sample of 150 employees who are familiar with organizational AI technologies. The results revealed that the availability of AI technologies significantly impacts organizations’ decisions to adopt those technologies in the UAE. In addition, the more the AI applications are available, the more the AI will be replacing humans in job positions and opportunities. On the other hand, perceived security, priva-cy, and technical risks can significantly influence organizations’ intentions to adopt AI technologies, and can, surprisingly, contribute to creating new job opportunities which serve the human side positively. The research concludes in some implications, limitation, and future directions.

Authors: Fei Junhui , Sun Beibei
Published: April 2022

The layout of a family dwelling has a significant impact on the living quality. Therefore, evaluation of the layout is very important. For the purpose of evaluating the layout of dwelling quantitatively, referring to spatial syntax, in this paper, three two-dimensional indicators, namely convenience, privacy and utility, are proposed after analyzing users’ psychological process and demand. First, dividing the interior plane into different sections, such as master bedroom and second bedroom, and then a mathematical model was proposed to calculate the relationships between each section including accessibility and correlation of each area referring to users' demands, so that users can evaluate the layout mathematically. The mathematical model provides a simple evaluation method for designers to design the apartment. It also provides a scientific basis for users to set out or remodel the apartment.
Simulation of Three-person Cooperation - Effect of Mutual Beliefs on Team Performance
Authors: Cho Sumie , Kanno Taro , Furuta Kazuo
Published: April 2022

Many human factor studies have explored the cognitive and behavioral factors that affect team performance by verbal protocol analysis and behavioral analysis. However, since the measurements used in these studies focused only on observable and recordable data, there is a fundamental limitation for understanding cognitive mechanisms behind those data. Computer simulation is an alternative method for exploring the cognitive aspects of human factors in team cooperation. In our previous study, therefore we developed an agent-based simulation of team cooperation using a team cognition model based on the concept of mutual beliefs and investigated how mutual beliefs affect better team performance. While the previous study modeled and focused only on a two-person team, the actual team in the real world often consists of three or more people, where more complicated cognitive processes are required than those in two-person cooperation. In this study, we developed an agent-based simulation of three-person team cooperation, employing the extended team cognition model considering mutual beliefs and mental subgrouping. This extended model describes cognitive processes in a team of three or larger with three different layers namely self-cognition, direct belief, and projected belief. We applied this model and simulation to the cooperative diagnosis problem of car failures and observed how a team collaboratively collects information on car parts, shares with other members, and identifies broken car parts. The results showed that the teams could share information effectively and identify the correct failures. The results also suggested that the communication generated by the mutual beliefs worked effectively and enhanced the team performance. We believe that our simulation is a promising method to compensate for the limitations of conventional human factor methods and explore cognitive aspects of team cooperation.

Published: April 2022

Current and future AI design needs to recognize the intertwined nature of cognition and affect to design more human-like intelligent systems. The majority of current AI design focuses on cognitive information processes and knowledge. However, human action and human-like actions must also consider the emotional aspects of the environment. We present the concept of emotional information space, which incorporates all issues within a certain environment with cognitively appraised affective meanings and the ability to encode these information contents into designing emotionally intelligent technologies.

Published: April 2022

Emotions are an essential part of our daily social interaction. They are highly complex processes and can cause different physiological, behavioral, and cognitive changes in individuals. A person for whom it is difficult or impossible to interpret emotions may face major problems in everyday life, e.g., patients with autism spectrum disorders. Understanding emotions is not only of great importance in private social interactions but also in the working environment, e.g., for managers or collaborative work. Initial research aims to positively influence behavior and outcomes of social interactions at work by emotion training. Additionally, the COVID-19 pandemic limited social interactions drastically. Due to isolation and contact restrictions, it is important to understand the impact on our ability to recognize emotions. Hence, there is a great interest in emotion research, including how emotions can be measured. For this purpose, a measuring environment was implemented that allows to detect a person’s emotional state. The aim of the presented study was to validate the measurement environment by evoking different emotions. As stimulus, affective visual material (EmoPicS) was used to address different emotional poles. To make emotions measurable, a multidimensional approach combining subjective and objective measures according to Boucsein and colleagues was chosen. Therefore, participants rated their emotional state using the Self-Assessment Manikin (SAM) on the three different affective dimensions: valence, arousal, and dominance. Also, facial expression was recorded as subjective measure. The objective psychophysiological measures were electrocardiogram (ECG), electrodermal activity (EDA) and electromyogram on the forearm and neck (EMG). Results prove a successful validation of the measurement environment. Furthermore, first findings show a significant difference regarding the subjective assessment of the affective visual material for the dimension valence. Nevertheless, no significant differences were found in the psychophysiological data for the stimulus material used. Future studies should use stronger stimuli to evoke emotions, e.g., by combining auditory and visual stimuli or using videos.

Authors: Danusevics Martins , Braslina Liga , Skiltere Daine , Batraga Anda , Braslins Girts
Published: April 2022

Problem statement. The development of construction projects requires a relatively long period of time, during which, according to historical data, construction costs change significantly even on an annual basis, which significantly affects the commercial opportunities of participants in the construction industry. Sometimes an inaccurate forecast can lead to the liquidation of a company or the suspension of a construction project. Many construction forecasting methods have been developed in recent decades, but their accuracy is fragmented. The latest machine learning methods are not yet able to produce accurate predictable calculations due to the high degree of uncertainty and variability in cost factors in the construction industry.Research aim. To further improve the quality of construction forecasting systems, the aim of the study was to develop and test a new modular prediction model of construction costs dynamics, which can forecast changes in the next 12M as accurately as possible, as well as to provide precise guidelines for five-year forecasts.Research methods used. The combined methodology of the study was developed in 2018 and for 3 years was approbated to assess changes in the costs and volume of the Latvian, EU member state, construction sectors. Each year during the summer period, a forecast was developed, and after a year, the results were compared, and the methodology was adjusted. The methodology is modular - it includes the use of both statistical and expert methods, a combination of methods. In total, more than 200 experts were interviewed over the 3-year survey, while the 2020 phase survey includes the opinions of 59 experts from 56 organizations according to the Quadruple Helix methodological approach. The quantitative data array consists of statistical data blocks by historical changes in the costs and volume of construction sub-sectors.Main results and findings of the study. Based on the improved methodology, the 2020 projections differed from the actual changes in 2020 by 0.4 percentage points in volume and 1.4 percentage points in costs in context where changes over the last decade have fluctuated in double-digit ranges. The results of the study identify high-precision construction cost and volume methodology.Theoretical and practical implications of the work and conclusions. The developed methodology can be applied in practical forecasts of construction costs and volume in both the public and private sectors. The developed methodology can be applied to the improvement of future construction forecasting, including the development of machine learning algorithms. The proposed forecasting method offers a new direction for construction cost forecasting research and will provide construction planners with an additional effective tool to manage the risks associated with construction project costs.

Authors: Chen Qian , Chen Yunfei , Huang Ziyue , Tang Lei
Published: April 2022

In the post-epidemic era, the application of computer-supported collaborative work (CSCW) in graphics and image software has become increasingly urgent. Collaborative image editing software allows users who are geographically dis-tributed in different locations to view and edit the same shared image object through the network. The interaction of the CSCW system includes human-computer interaction and human-to-human interaction, and human-to-human in-teraction expands the time and space of interaction, and also strengthens the freedom of interaction between user groups. The research object of this article is the interactive key elements of the graphics and image software on the mo-bile terminal in the collaborative editing state, that is, the current operating state of the system and related information. By analyzing the interactive ele-ments of collaborative office software and image and image software on the PC and mobile terminals by competing products, the three key elements of in-teractive design in cscw-based graphics and image software are extracted: edi-tor information, selected status, and Information display location. This paper redesigned these three elements to obtain a high-fidelity model of the graphics configuration of the mobile graphics and image software during collaborative editing operations. Through the usability test and QUIS questionnaire, we verified its usability and got good user satisfaction. Finally, the design guide-lines for the optimal interactive graphics configuration of the mobile graphics and image software in the collaborative editing state are obtained. The interac-tive design guidelines proposed in this paper can be used as a design refer-ence for the collaborative editing image software on the mobile terminal.

Authors: Liu Xia , Zhang Yan
Published: April 2022

In web design, important text information is placed in the visual center of people, when there is too much information, it will cause the imbalance of interface layout. Color plays an important role in interface balance as a per-ceptive element. This paper introduces the experimental study on the effect of color brightness on interface balance. In this experiment, 11 geometric images were designed to verify the effect of brightness on the balance sub-ject score by changing the brightness properties only. The results of the ex-periment showed that compared with the reference image (50% of bright-ness), male and female subjects gave a score lower than the reference image when the image brightness was less than 50% or higher, and the test image was greater than 50%, and the score decreased linearly with the decrease of the image brightness.

Authors: Ulahannan Arun , Zdanowicz Katie , Bowie Cameron , Birrell Stewart
Published: April 2022

Wireless charging could allow drivers to better manage their vehicle’s range through more frequent, if slower, charging. However, accurate alignment between the vehicle and the ground pad is crucial. 12 participants were asked to align either the front or rear of a wireless-enabled vehicle, with a ground pad; both with and without the support of an in-vehicle alignment HMI. We found that participants were most accurate when front aligning the vehicle. The alignment HMI significantly improved longitudinal alignment in all conditions. However, when front aligning, lateral alignment was not significantly improved by the HMI. Alignment was poorest when the vehicle pad was at the rear of the vehicle. We found that 100% of participants could align accurately enough to begin charging with the aid of the HMI, followed by only 17% for unassisted front aligning and 0% when rear aligning; highlighting the importance of pad location and HMI support.

Published: April 2022

Craft design has gone through different contexts, and the craftsmanship in the new age is different from that in the industrial age. By analyzing the evolution and new scenario of craft design, the paper summarizes the trend of new craft design. The evolution of craft design shows the following trends: 1) the output diversified to satisfy the new needs due to technological advancement, including the material object, experience, service, and digital content. 2) the responsibility shifts from product design to activity design. 3) the boundaries are blurred; more and more industries, disciplines and people are participating in craft design. This paper believes that the new craft design has two directions: one points to the craftsmanship itself (tangible-intermediate-intangible structure); the other points to the various relationships with other disciplines, environment, and society.

Authors: Song Hao , Zhang Yan
Published: April 2022

In order to study the dynamic response of the dust collector in the process of free fall, the author used the HYPERMESH/LS-DYNA software to simulate the fall-ing process; set up a drop test platform and used a high-speed camera to record the collision process, and used sensors to obtain parameters such as impact force and acceleration during the fall. Finally, the experimental results are compared with the simulation results. The results show that: (1) The numerical simulation shows the collision process of the dust collector very well, which is very con-sistent with the part disengagement and structural deformation that occurred in the experiment. (2) The impact force and acceleration values obtained by simulation and experiment are relatively close, which also verifies the reliability of the simu-lation. This study evaluated the impact resistance of the dust bucket, which con-tributed to the reduction of product development costs and subsequent structural improvements.

Published: April 2022

Work fatigue is one of the main causes of accidents. The main purpose of this article is to discuss the mapping relationship between eyelid closure data and human fatigue at work through confirmatory experiments, and the applicability of composite eye movement parameter analysis based on the random forest neural network model for fatigue detection in specific tasks . A total of 16 subjects were recruited in this experiment. The performance of the subjects was obtained by the improved measurement method of the number of cancellation symbols, and the reaction time of the subjects was obtained by the two-point click reaction time measurement method. The obtained performance and response time data are used to reflect the fatigue degree of the subjects, and the Diskablis eye tracker is used to record the eye movement parameters of the subjects. Finally, it was found that PERCLOS and the two-point click response time had a correlation with fatigue status in time sequence, and there was a more potential relationship between other performance parameters and fatigue. The comprehensive eye movement parameter analysis based on the random forest neural network model has also been confirmed to have high usability in fatigue detection.

Published: April 2022

With the development of miniaturization and high density of microwave modules, package on package (POP) configuration has been widely used. Ceramic ball grid array (CBGA) solder joints provide effective microwave signal interconnection and mechanical support between high temperature co-fired ceramic (HTCC) substrates. A CBGA solder joints T/R module based on HTCC substrate is introduced in this paper. In the process of reflow sol-dering, the T/R module may fail due to HTCC substrate cracking or CBGA solder joints falling off. Therefore, the finite element thermo-mechanical coupling analysis method is used in this paper to explore the failure causes. Besides, several factors such as HTCC substrate thickness, substrate size, cavity proportion and shell material are selected for orthogonal experimental design to study the effects of the above factors on the warpage and stress of T/R module during reflow soldering, which has certain guiding significance for the production of T/R module.

Graduate Student Safety Culture
Authors: Ostrom Lee
Published: April 2022

A culture is a collective of social norms, mannerisms, religion, language, activities, environment, and other factors that help to make us who we are. Within any culture lies its safety culture. How does an organization assess its safety culture? One method is to interview every person in an organization. However, this is impractical. Properly constructed safety surveys provide information that can be used to assess and to help improve an organization’s safety culture. Laboratory experiments of varying levels of hazards are conducted every day around the world in colleges and universities. These experiments are for basic and applied research and for teaching undergraduate and graduate students how to conduct research. Generally, these experiments are conducted safely. Many accidents have occurred in University Laboratories. Some are very horrific. This paper discusses one such accident and discusses two universities’ safety culture surveys and presents some results from the surveys.

Published: April 2022

The environment of the basic education has changed during the last few years. The children's needs are more manifold than before and there are more children who need special needs education. The implementation methods of the special needs education have changed with the inclusion (one school to everybody). The changes in the environment have challenged teachers in many different ways. The special needs teachers work in the cooperation, between the units of the separate actors, such as teachers, school psychologists, school welfare officers, a psychiatric nurse, home and child protection, which for its part increases the load of the work and may cause the feeling of the inadequacy.Ensuring and maintaining the working capacity of employees is one objective of the Finnish Occupational Safety Act. According to the act, the employer has a responsibility to make sure that the work does not load worker too much. It is important to identify the work load factors, because it is the foundation of the safety work. The article is about what are the workload factors in the special needs teacher's work. The work load factors are analysed in the framework of the well-being at work. It is attempt to find factors of well-being at work, which are significant from point of view of the work load and management. The special needs teachers of one Finnish municipality participated in the study. The data for this paper was collected through well-being survey (n=35) and workshops. The process and methods will be described in the article.The results of the preliminary data analysis indicate that work of the special needs teachers is experienced to be mentally and ethically burden. According to well-being survey the working environment and conditions were not mainly considered to be the work load factors. The special needs teachers indeed experience the feeling of the inadequacy in their work which for its part adds the load of the work. Daily work needs to be done in hurry. It is not possible to do the work as well as wanted. The paper contributes to prior research by providing new information about workload factors in special needs teachers’ work. It is important to support the special needs teachers' work welfare because it has reflections in the pupils and their families, but also to other teachers and special needs assistants.
Intuitive Body Operations Suppressing VR Sickness
Authors: Utusmi Naoto , Takimoto Munehiro , Kambayashi Yasushi
Published: April 2022

We propose a user interface that provides users feeling of immersion in virtual space. Recently technological progress of devices that give users illusions as if they were exercising their arms and legs in virtual space have been remarkable, and contents for such devices have been popular. Especially, Virtual Reality (VR) contents that provide interaction between users and objects in virtual space have attracted more and more attention. Some of them help users to immerse in virtual space. VR technology has put many interactions into practice that are impossible in physical space. In the current practice, however, most user’s behaviors in VR contents are limited to ones that are possible in physical space such as exploring a dungeon in a fantasy game. In this paper, we propose a novel and intuitive moving manner of users’ body in virtual space. Traditionally, in most VR contents, a user has moved by walking or riding a vehicle two dimensionally. If he would like to move three dimensionally, he has to rely on a conventional operation such as a joystick, mouse or keyboard other than intuitive body actions. Such three dimensional movements in the virtual space through conventional operations, however, causes VR sickness because of movement of the sight without any body action. There are measures of mitigation to prevent VR sickness. For examples, some systems suppress the VR sickness through a body action such as stepping to go forward. We have designed a moving manner including up-and-down movement with intuitive and highly immersive body actions. In our system, a user rides a popular fitness equipment, which has two pedals for left and right feet, and he or she can open or close his legs by sliding the pedals to the sides on it. On the equipment, the user can designate movement to any directions through body actions. If he wants to go forward, he can wave his arms as if he is walking. Also, if he wants to go up, he can shake his legs in a flurrying manner as if a bird flaps its wings. In order to stay in the air, he holds his legs widely. On the other hand, in order to go down, he holds his legs narrowly. Those movement of limbs’ actions give the user feeling of motions, which contributes to enhancing his immersion while suppressing VR sickness. In order to show the effectiveness of our approach, we conducted experiments to compare our method with a conventional method using a controller. We had the subjects move around the same course in a 3D virtual stage with these methods, and verified the degree of the sense of immersion and development of VR sickness. As a result, we observed that our method increases the sense of immersion and reduces VR sickness.

Published: April 2022

Nowadays, online route planners for soft modes are provided by several platforms such as Google Maps, OpenStreetMap, Here, or Waze. Itineraries are usually built using Shortest Path Problem algorithms that minimize the travel time or distance. In this work, we aim to identify and quantify the main features that influence itineraries’ choice by soft modes users in urban areas, able to support multi-objective routing, using simulated scenarios. We propose a set of 21 indicators, grouped into five dimensions: Safety-Security, Comfort, Air Quality, Accessibility and Time-Distance. Another contribution of this work is the simulation of scenarios to study soft modes’ multi-objective routing within urban areas.

Technical haptic parame-ters were identified that promise favorable impressions. Future research should use a test-rig to enable specific manipulation of technical parameters.
Virtual learning environment applying digital narratives methodology
Authors: Guevara Cesar , Paredes Juan
Published: April 2022

The world in recent times has experienced an unprecedented advance in the development of Information and Communication Technologies (ICT), as indicated by United Nations Organization (UN) in 2019. The UN highlights that the influence of new digital technologies has transformed society, reaching more than 50% of the world's population in the last 20 years. In this context, education as a key piece in the development of society, must become a benchmark when innovating its teaching processes, with the purpose of reaching more and more segments of the population with affordable technological tools that provide quality educational processes. Thus, virtual learning environments (VLE) have become spaces where it has been possible to move the classroom to virtual world. This technology has introduced new methodologies, interactive material, and various ways of presenting information. This study proposes the development of a virtual learning environment as a space to study the topic of internal combustion engines, applying digital narratives methodology. Through bibliographic and documentary research, it has been found that this strategy fosters various capacities in students, based on visual and auditory stimulation, facilitating learning and retention of information. For the development of the virtual classroom, the theme will focus on the theoretical study of the internal combustion engine operating cycle. To accomplish this, the Moodle platform has been used, considering it the most suitable because its design provides both students and teachers with a personalized, robust, and safe environment. The functionalities of the virtual classroom will consist of providing the student with a visually attractive space both in structure and content. For this, there will be tools, Moodle environment typical activities and others that are available online, which facilitate the creation of educational content. The proposed prototype seeks to become a space that complements the work developed in conventional learning. Thus, the contents of the virtual classroom are intended to bring the student closer to the subject to be developed in class and afterwards consolidate what has been learned. With this, it is expected to improve academic performance through constant motivation towards the study of the subject, also contributing to collaborative work before, during and after face-to-face sessions.

Authors: Guevara Cesar , Espinosa Lorena , Suarez Roilys
Published: April 2022

Many are the educational models and approaches that have been used throughout decades in the world. These have had their variations and changes such as evolution and epistemology of educational processes. Despite this, many times teaching continues under traditional models that do not open the full development of students and do not favor sustainable social development in general. Applying the methodology of training projects from socioformation favors key goals such as forming and consolidating the ethical life project, having entrepreneurship, developing the necessary skills to face the challenges of the context, and working collaboratively. On the other hand, it consists on a strategy in which articulated activities are proposed in order to solve challenges or problems of the context, favoring the communities or areas where it is applied. And it is applied from the socioformation since it is a new approach based on the ethical project of life, entrepreneurship, the development of skills and collaborative work. In this way, the problems to be solved through the training projects would be significant for the students, since it makes them feel active entities in the process, and in turn, useful to the society where they develop as individuals. For this reason, the application of training projects is proposed from socioformation in education, especially at the university level. When applying the research, the deficient planning of the training project from the socio-formative model of the Indoamérica Technological University could be detected as a problem. The purpose is to present an improvement in the planning of a training project in the area of English. The applied methodology is the analysis of a training project from the socioformation, with the aim of improving the planning processes following certain educational references such as trans disciplinarity, collaborative work, the rubric, and the final product, contributing to the solution of a real problem of the context. Results were obtained such as the evaluation of the didactic planning practice of the training project, achievements and aspects to be improved were identified and on that basis a new planning of the project was proposed from the socioformation. It was possible to verify as conclusions that the methodology proposed from the socioformation to develop the didactic planning in the training project presents very positive aspects, since the activities are articulated to achieve a desired end as a final product. In addition, students learn in a contextualized way, solving environmental challenges, contributing to sustainable social development.

mHealthINX is an international research project that aims to design and develop a digital-based solution that supports older employees (55+) in pro-moting and strengthening their mental health. Age-related decline of physi-cal and cognitive abilities can raise challenges and stressful situations for older adults at work. Although older workers are in general more capable of managing and coping with stress-related situations than their younger coun-terparts, at some point, many become overwhelmed, can experience a de-crease in their productivity, or face a higher risk of health-related issues. mHealthINX seeks to alleviate these problems by providing a user-friendly digital solution that supports older employees in monitoring their stress lev-els, make themselves aware of stressors, and preventing stress-related conse-quences. The prototype will provide mental health assessments and mental health-promoting features such as cognitive training, mindfulness, and techniques and tools supporting users in learning to cope with stressors. This work aims to depict the mHealthINX solution's concept and highlight the in-terplay between it’s frontend components. Next to the concept, this work fo-cuses on the user experience and user involvement results gained from the first and second workshops held in Switzerland and the Netherlands.
Cultural difference of simplified facial expressions

In this research, the authors succeeded in creating facial expressions made with the minimum necessary elements for recognizing a face. The elements are two eyes and a mouth made using precise circles, which are transformed to make facial expressions geometrically, through rotation and vertically scaling transformation. The facial expression patterns made by the geometric elements and transformations were composed employing three dimensions of visual in-formation that had been suggested by many previous researches, slantedness, of the mouth, openness of the face, and slantedness of the eyes. The authors also surveyed cultural differences of impressions of such simplified faces.
Exploration of Multi-Touch Sliding Gesture Usage in In-Vehicle Infotainment System

Published: April 2022

Although more and more functions are integrated into the center touch screens, many researchers have proved that touch screens might distract drivers’ attention and cause accidents. Voice controls were also proved mentally straining and takes long interaction times. This article explored the practicability of multi-touch sliding gesture operations, basing on multi-touch screens or touchpads that are already widely used in vehicles. We built a multi-touch sliding gesture In-Vehicle Infotainment (IVI) system and a traditional touch IVI system, then evaluated them from both subjective and objective perspectives. The results are very positive: by using sliding gesture op-erations, the eye off-road time reduced 87.3%, the off-lane counts reduced 86.84% and the accident rate reduced from 7.5% to 0%. The driving activity load score reduced by more than half and the User Experience Questionnaire scored 2 ranks better.
Using prototype heuristics in reverse innovation engineering as an effective process for design-based learning

Published: April 2022

Design-Based Learning (DBL) teaching can induce critical thinking and im-prove problem solving. Design is considered as a cognitive process in which we are dealing complicated message under ive problem definition. However, students are struggle as their limited experience. This research de-velops a multidisciplinary curriculum for effectively learning innovative prop-osition by reverse-engineering design thinking patterns. Totally, 36 students in the industrial design of Tatung University were the experimental subjects, 18 of whom comprised the experimental group. The design process teaching of reverse engineering and prototype-heuristics cards the research teams de-signed was used as the guide. After the project, the students in the experi-mental group were able to think more effectively, learn to change the design parameters, and focus more quickly on the knowledge that should be self-learning, and the tools allows students to synchronize their ideas with those of their teachers, whereby students can reduce their reliance on teachers’ suggestions.
