Abstract

Multimedia learning is defined as the process of forming a knowledge mental model from words and pictures. It is important to measure cognitive process during multimedia learning. Differences in learners’ capabilities can be investigated through cognitive processes to improve the learning process. However, conventional methods such as interviews or behavioural assessment do not provide an objective measurement of cognitive processes during multimedia learning. Some advance methods to measure cognitive processes takes into account learner’s eye movement during learning process. In such a case, eye-tracking can be used as an alternative method to measure cognitive processes because eye movement has become a major part of human cognitive function. Another issue is related to the learners with different gender, which might have different styles of interaction with the source of information. Unfortunately, the effect of gender disparities in multimedia learning has not been widely studied. To address this research gap, this study examines the effect of gender differences based on eye-tracking metrics during multimedia learning. Based on the experimental results, `time until first fixation` on the text-type area of interest (AOI), `number of fixations` on the image type AOI, and `transition` from text-type AOI to image-type as well as `transition` between Image AOIs provided notable distinctions for each gender group (p < 0.05). It was found that male learners preferred to access information from images. In contrast, female learners tended to do a thorough inspection on textual and pictorial information during multimedia learning. This study can be used as an alternative method for collecting cognitive process indicators in multimedia learning.

Abstract

An arrester is a device that serves to protect equipment from dielectric failure caused by lightning impulses, switching surges, or voltage spikes that exceed an equipment’s dielectric capability. The majority of arresters have an event counter installed, which is used to track how frequently they have been in use. In humid and heavily polluted environmental conditions, it is very easy for surface discharge to occur on the isolator. Surface discharge is a discharge that occurs in an area directly related to a dielectric surface that has an excess electric field, thus triggering a discharge. If a surface discharge continues to happen, it can result in a flashover. Flashover that hits part of the event counter can make the event counter experience error, so it does not show the correct number. In addition, the performance of the event counter will be disrupted. For this reason, it is necessary to test the arrester insulators with three schemes: clean condition insulators, humid condition insulators, and insulators with humid and polluted conditions. In this experiment, pollutants were used with an equivalent salt deposit density (ESDD) value of 4.69 mg/cm2 and a nonsoluble deposit density (NSDD) value of 1.8841 mg/cm2. According to the experiment results, it was found that there was a decrease in the ability of arrester insulation to withstand voltage caused by humidity and pollutants. Humidity decreased breakdown voltage (BDV) by 5.8 kV for every 5% increase in humidity, while pollutants decreased BDV by 59 kV when the insulator was exposed to pollutants.
