“…Although new possibilities may range up to automation of all processes carried out in classroom settings, and despite research is already reporting results (Abdel-Basset, Manogaran, Mohamed & Rushdy, 2019) (Zawacki-Richter, Marín, Bond & Gouverneur, 2019), this literature review on acoustics juxtaposed to the smart classrooms conceptualisation shows that we are still far from such advanced solutions to be implemented in schools. Short-term advances will rather consider systems for improving sound quality and reducing noise (Russo & Ruggiero, 2018), systems for giving teachers insights into current needs (Jayahari et al, 2017), devices for controlling sound exposure (Guntha et al, 2016) and designs aimed at providing more sustainable settings (Tahsildoost & Zomorodian, 2018).…”

“…The 4IR introduces in education Big Data, Artificial Intelligence, Internet of Things and other possibilities (Zhong, Xu, Klotz & Newman, 2017), making it possible to improve the personalisation of learning experiences and offering a much more effective teaching system (Mogas et al, 2020). By using the mentioned advances or less complex solutions, controlling acoustics in smart classrooms appear in the form of systems for improving sound quality and reducing noise (Russo & Ruggiero, 2018), systems for giving teachers insights into current needs (Jayahari, Beenu & Bijlani, 2017), devices for controlling sound exposure (Guntha, Hariharan & Rangan, 2016) and designs aimed at providing greener and more sustainable settings (Tahsildoost & Zomorodian, 2018;Trematerra & Lombardi, 2017;Iannace, Trematerra & Trematerra, 2014). Indeed, sustainability also plays a key role in acoustics for smart classrooms (Roy, 2010).…”

Acoustics in schools have been studied during years, but nowadays there are more possibilities than ever before to introduce improvements. This study presents a systematic literature review determining what acoustic parameters are present in classrooms and how they affect both teachers and students. Following the analysis, we put forward a two-block classification: the physical parameters of the sound or noise in the classroom and the consequences of the acoustics on the people in the classroom. Advances in the design of learning spaces and the use of technologies ranging from devices and green material to advanced automation systems make it possible to direct acoustic solutions toward smarter learning spaces. This review also highlights the acoustic parameters to consider in smart classrooms (noise, reverberation, speech transmission and speech clarity) and the main effects of acoustics on teachers and students. Some conclusions and recommendations are drawn, but more research is needed in terms of school improvement considering acoustics influence and smart classrooms possibilities.

“…The effects of physical variables in educational environments on students have been analyzed in some studies in the literature with temperature (Alberto et al, 2021;Wargocki & Wyon, 2007), sound (Guntha et al, 2016), and air quality (Bako-Biro et al, 2012;Mazutti et al, 2020) being analyzed in more detail; however, humidity has been considered together with temperature (Orosa et al, 2014). Studies concerning physical variables claim that light (Barrett et al, 2015) or sound (Uzelac et al, 2015) is the physical variable that affects students the most.…”

“…There are certain variables in psychological environments, such as attitudes, attention, motivation, and perception, that are important in learning (Driscoll, 2000;Schunk, 2012;Solso et al, 2007). Physical environments, on the other hand, contain several physical variables, such as the size, the shape, and the internal architecture of educational environments, air quality, sound level, intensity of light, and amount of humidity and temperature (Guntha et al, 2016;Lei, 2010;Wells & Daunt, 2016).…”

This study aims to examine the effects of physical variables (temperature, humidity, air quality, light, and sound) and those pertaining to the monitoring these physical variables on a group of students in terms of attention, motivation, attitudes, and perceptions of academic achievement (POA). The students were provided with a chance to monitor the physical variables through the Internet of Things (IoT) technology. This study employed a causal comparative design, which is a quantitative research method. The sample chosen by convenience sampling consisted of 262 undergraduate students from five different educational environments in the faculty of education of a large state university located in the Northeast Turkey. A prototype measuring the physical variables of the educational environments and enabling to send these to the internet was developed in the context of an IoT application, and it was ensured that the students in the five different educational environments monitored the physical variables for six weeks. Data were collected by use of the prototype created in the framework of IoT and a questionnaire. Consequently, it was concluded that the physical variables did not have significant effects on attitudes, but temperature, air quality, light, and sound had significant effects on students’ attention, motivation, and perceptions of academic achievement. Furthermore, results showed that monitoring the physical variables caused a difference in the students’ motivation, attention, attitudes, and POA.

“…A smart classroom is an enclosed space that uses technologies to improve the teaching and learning process [1,38]. A standard smart classroom has improved presentation [4], student participation [39], better contact [40], and improved physical surroundings [41]. It can also provide resources for taking attendance [42], assessing [43], and providing real-time reviews [44].…”

A Survey of Smart Classroom Literature

2022

View full text Add to dashboard Cite

Recently, there has been a substantial amount of research on smart classrooms, encompassing a number of areas, including Information and Communication Technology, Machine Learning, Sensor Networks, Cloud Computing, and Hardware. Smart classroom research has been quickly implemented to enhance education systems, resulting in higher engagement and empowerment of students, educators, and administrators. Despite decades of using emerging technology to improve teaching practices, critics often point out that methods miss adequate theoretical and technical foundations. As a result, there have been a number of conflicting reviews on different perspectives of smart classrooms. For a realistic smart classroom approach, a piecemeal implementation is insufficient. This survey contributes to the current literature by presenting a comprehensive analysis of various disciplines using a standard terminology and taxonomy. This multi-field study reveals new research possibilities and problems that must be tackled in order to integrate interdisciplinary works in a synergic manner. Our analysis shows that smart classroom is a rapidly developing research area that complements a number of emerging technologies. Moreover, this paper also describes the co-occurrence network of technological keywords using VOSviewer for an in-depth analysis.
