### Applications of TAM  
[PERSON] [6] proposed the TAM to predict or elucidate the factors affecting IT use, based on the TRA (theory of reasoned action) by [PERSON] and [PERSON] [7] and the TPB (theory of planned behavior) by [PERSON] [8], in which the TAM was extended and developed, and consisted of two beliefs: perceived ease of use and perceived usefulness. The former referred to the ease of use of IT (information technology) subjectively perceived by users. The easier the use, the more accepted the IT. The latter referred to the extent of usefulness of IT subjectively perceived by users. The more extent the usefulness, the more adopted the IT. The recognition affected the attitudes and furthered the behaviors. TAM was employed to elucidate and predicate the acceptance of use of IT in which the use intention and behavior of individuals were affected by two key variables: perceived ease of use and perceived usefulness.  
A study on using mobile devices was conducted in a university. The 678 participants were primary education teachers who achieved a Bachelor's degree. The results showed that a strong relationship exists between perceived usefulness and behavioral intention [9]. Another study considered the teaching-learning activity by using YouTube [10]. One of the findings presented the significance of the relationship between different variables and the behavioral intention, validating the TAM. Another example is a study that focused on cognitive-oriented individual differences in order to integrate relevant features between users and systems. The results show that both the learning styles and teaching styles on using behaviors of e-Learning systems affected the intention [11].  
From the perspective of education, many researchers have also deliberated profoundly on TAM. One study examined YouTube as a learning resource in higher education. The research objectives were scale development and validated the TAM [10]. Through the TAM model, a study examined the attitude of Turkish EFL learners towards technology. The results showed some of the TAM factors have effects on the learning performance [12]. Another study also used TAM to study pre-service teachers' intent to use Mobile-Learning, and the results showed that there was a significant difference between control and experimental groups [9]. In this study, we examine the relationships among factors of TAM. Through the study, we understand the determinates on the intention to use.  
However, the relationships among TAM model may not always be significant. A study aimed to investigate the attitude of learners toward an augmented reality (AR) learning activity. It was designed to help engineering students solve an electromagnetic problem. The participants were 122 students. The results of the evaluation show that intention of using the system is dependent on the perceived enjoyment, but not from the perceived usefulness of the learning tool [13].  
According to the related research above, TAM has mostly been extensively employed, effectively and suitably, to elucidate and predict the personal acceptance of use of multimedia.  
This study investigated the use intention of multimedia teaching material of elementary school teachers.
