It uses tele- communication tools to provide knowledge for lesson and practice. Online learning creates a high demand from business and institutes of higher institution. Other than that, it is a great in learning on modern society. During Movement Control Order (MCO) due to pandemic Covid-19, universities embark online learning for the student to attend the class without physical attendance either they stay in campus’s hostel or off campus at their home. Online learning outside the classroom especially at home apparently will give different experience to the student because of different surrounding environment. Therefore, the student attention and focus during the online teaching may different compare to learning during physical classroom and there is a tendency of frequent movement while attending the online classroom. Based on this possible scenario of online leaning classroom, this study carried out to track the student’s movement and 80 http://www.i-jim.org https://doi.org/10.3991/ijim.v15i18.24731 mailto:mamran@unikl.edu.my Paper—Exploratory Study on the Online Learning Understanding Based on Movement and Condition… conditions in sitting position while online class conducted and to find the relationship of these movement with the level of understanding of online learning during Movement Control Order (MCO) due to pandemic Covid-19. 2 Revolution of online learning Salazar et al. [1] study the use of technology in learning activity that eventually contrbute to the revolution of online learning. As shown in Figure 1, this study stated that there are four type of learning method which are traditional learning method, E-learning, M-learning, and U-learning. Traditional learning method frontal teaching methods that mostly rely on technical teaching method and require face to face session. The E-learning method ideal for long-distance learning, and learners can learn when they have internet connectivity. The E-learning method require to have a computer and network to conduct this session. However, the E-learning decreases the interactions between teachers and students among other students. M-learning (Mobile learning) is a way to allow a student to study with a portable device such as smartphones from any location at any available time. However, it can make students anti-social so that it is known as a passive model of learning like e-learning. U-learning is defined as an active learning pattern compared with M-learning and enables students to gather knowledge from the learning environment through different sensor types. Fig. 1. Revolution of online learning [1] 3 Sensor parameters Nowadays, smartphone consists a bunch of varieties and powerful sensors which are gives an opportunity for human interactions and connections, mainly in the most iJIM ‒ Vol. 15, No. 18, 2021 81 Paper—Exploratory Study on the Online Learning Understanding Based on Movement and Condition… developed countries. In daily life, people bring the smartphone everywhere. The sen- sors in smartphone can give the information and news updated. Thus, promote a richer chances and experience for user through the development of the sensors days by days. Smartphone sensors have abilities to collect data and quantities hence create innovative applications. The access of exploring the smartphone recently have no limit. All the information, knowledge or anything that we need are also in our fingertips. A sensor is a device, module or machine to detect any changes happen in its sur- rounding and transmit the input to other from the physical environment. The types of sensor could be light, heat, motion, humidity, light intensity or any other environmental phenomena. In broader benefit, sensors are used in daily life for instance touch-sensitive elevator buttons, lamp auto on in toilet and many others. To track and record the student movement while attending the online classroom, the smartphone sensors is used. The Apps AndroSensor is used to measure the Light inten- sity (lux), Orientation (axis x, y and z), Sound Level (dB) and Heart Rate (bpm). Below Table 1 summarize the parameters used in this study.

From the above result, due to normality test show that the data is not normal this study using median as an answer and thus the level of understanding for these students is at scale 4. Subsequent objective of the study is trying to identify the relationship between move- ment condition and sensor’s parameters sensed by smartphone application. This study found the relationship by using Multiple Linear Regression with 43.25% of R-Square is shown as below. Level of understanding = 5.239 − 0.00857 Heart Rate + 0.002736 Light (lux) + 0.1308 Orientation X (pitch °) + 0.0762 Orientation Y (roll °) − 0.1230 Orientation Z (azimuth °) − 0.02127 Sound Level (dB) The level of understanding when study through online leaning can be predicted through this Multiple Linear Regression formula. The application if this prediction is illustrated as below. Heart Rate = 89 bpm Light of Intensity = 458 lux Sensor Orientation X = −6.530 pitch  Sensor Orientation Y = 7.000 roll  Sensor Orientation Z = −5.460 azimuth  Sound Level = 60 dB Question: Based on above data what is the predicted level of understanding when study through online learning? Multiple Linear Regression formula: Level of understanding = 5.239 − 0.00857 Heart Rate + 0.002736 Light (lux) + 0.1308 Orientation X (pitch Â) + 0.0762 Orientation Y (roll Â) − 0.1230 Orienta- tion Z (azimuth Â) − 0.02127 Sound Level (dB) Substitute the data into the formula: Level of understanding = 5.239 − 0.00857 (89) + 0.002736 (458) + 0.1308 (−6.530) + 0.0762 (7) − 0.1230 (−5.460) − 0.02127 (60) = 4.47627 + 1.253088 – 0.854124 + 0.5334 + 0.67158 – 1.2762 = 4.804014 8 Acknowledgement Thank you to Corresponding Authors which are Ts.
