Assessing effectiveness of wood spray painting system model for undergraduate engineering education

Abstract

In this study, the effectiveness of an experimental model of spray painting system (SPS) for wood products in engineering education was evaluated based on students' mental workload (MWL). The subjective rating method, NASA‐task load index (NASA‐TLX), was used to evaluate the MWL of 34 students and 8 experts. The results of the data analysis showed that the assessment of the students' MWL was higher than that of the experts. Hence, the research indicated the need to improve the practical content in order to reduce the student MWL. In addition, the results demonstrated that students' MWL could be used to consider the effectiveness of the experimental model in engineering education, thereby improving the model's efficiency and the quality of training.

“…33,34 While biases, response sets, errors, and protest attitudes can affect the results obtained through rating scales, the low cost, ease of administration, and adaptability of this method have made it highly valuable in various domains, including industrial systems, 27,[35][36][37] office environments, 38 and educational assessments. 18,23,24 In this study, the NASA Task Load Index (NASA-TLX) was used to evaluate student's MWL. This is a subjective workload-rating method that takes into account multiple dimensions.…”

“…The findings revealed that increased levels of task load associated with mobile learning technologies led to physical ergonomic discomfort and influenced students' perceptions of MWL. Tran et al 18 evaluated the effectiveness of an experimental model of spray-painting system for wood products in engineering education by using the subjective rating method of MWL. The results showed that students' MWL could be considered when assessing the effectiveness of the experimental model, leading to improved efficiency and quality of training.…”
