1. Introduction
The construction industry has recently adopted Building Information Modeling (BIM). Moreover, research and education on BIM technology have become a prevalent topic for builders and educators in the construction industry [
1,
2]. Relevant research shows that the popularization and application of BIM technology have undergone a significant transformation in the architecture, engineering, and construction (AEC) industry, which has increased the employment competition of fresh graduates of those majors [
3]. Moreover, college students’ mastery of BIM technology can promote the application of BIM technology in the whole construction industry and make the industry more efficient [
1]. Such a reinforcing circle should be strengthened to accelerate the industry transformation. Therefore, it is necessary to understand the current situation of BIM technology learning behavior among college students and analyze the significant positive influence path of such behavior so that better education can be provided to stimulate the reinforcing circle.
In the BIM application and education domain, scholars mainly focus on correlating industry, project, and education aspects. For example, Ebrahimi et al. [
4] seek the interactions of sustainability and BIM in support of existing buildings. Eadie et al. [
5] conducted a survey on the use of BIM in the project life cycle, showing that the BIM industry lacks professional knowledge and training, and relevant BIM educators get more opportunities. Moreover, Tsai et al. [
6] developed a new online BIM learning course, focusing on improving the BIM education mode. Jia [
7] compared the BIM courses in Chinese and American universities and suggested that the BIM courses in China should be integrated with traditional courses. Meanwhile, Guo et al. [
8] explored how to bridge the gaps between BIM education and practice from a competency-based education perspective. In contrast, Ding et al. [
9] explore the key factors that affect practitioners’ adoption of BIM. Their study showed that BIM motivation, BIM technical barriers, and BIM ability are the significant factors that affect architects’ adoption of BIM technology. Howard et al. [
10] use the Unified Theory of Acceptance and Use of Technology (UTAUT) model to understand the individuals’ perceptions towards working with BIM. The results reveal that performance expectancy does not directly affect behavioral intention of personal participation in BIM, signifying that BIM is perceived as an unrewarded addition to existing work processes.
Reviewing the existing literature, it is found that there is a relative lack of research on the learning behavior of BIM technology from the perspective of individual students. In recent years, exploring BIM education from students’ perspectives has been encouraged. Agirbas [
11] pointed out that students’ positive attitude towards using BIM software may improve their learning efficiency of professional architectural knowledge. In addition, through the evaluation of BIM learning achievement in China’s Sixth National BIM Graduation Design Innovation Competition of Colleges and Universities, Ao et al. [
1] found seven public factors that affect BIM learning performance: (1) ability of the instructor, (2) school (college) atmosphere, (3) teamwork, (4) individual ability, (5) understanding of BIM industry applications, (6) social environment incentives, and (7) achievement demand. Furthermore, referring to the body of work that exists, this research combines the theory of UTAUT to analyze the influencing factors of college students’ BIM learning intention and behavior and their influencing relationships from the perspective of individual learners, aiming at exploring and developing the path of BIM education.
3. Materials and Methods
3.1. Model Construction and Research Hypothesis
This research draws lessons from the existing UTAUT theoretical research results and combines the characteristics of college students, higher education, and BIM technology learning to construct a model of influencing factors of college students’ BIM technology learning intention and behavior. This research model retains the four key factors in the classic UTAUT model: performance expectancy, effort expectancy, social influence and facilitating conditions. “Attitude” is also considered a very strong factor affecting behavioral intention [
52,
53], so this research considers “attitude” a critical variable in the model. In addition, Dwivedi et al. [
54] also mention that most studies using UTAUT often gave up the use of regulatory variables. Arif et al. [
55] did not observe the moderating effect of age, gender, and experience in the study of influencing factors on students’ use of distance education based on network services. At the same time, because BIM technology is a compulsory course for AEC majors in most Chinese universities, age, gender, experience, and voluntariness were excluded from the regulated variables. Therefore, the theoretical framework model proposed in this research is shown in
Figure 1.
By summarizing the existing research results, this study puts forward the following research hypotheses, as shown in
Table 1.
3.2. Questionnaire Design
Based on the scale recorded in the existing literature, combined with the BIM learning situation of Chinese AEC majors, this study’s designed questionnaire mainly includes two parts: the first part records the basic information of AEC majors in universities in China, including the interviewees’ gender, age, grade, major, BIM knowledge, and access to BIM courses, and so forth. The second part measures students’ intention and behavior to learn BIM and adopts a Likert five-component scale to measure the degree of each observed variable with 1–5 indicating “totally disagree”, “basically disagree”, “average”, “basically agree”, and “totally agree” respectively. The measurement scale of the questionnaire mainly comes from the UTAUT scale proposed by Venkatesh et al. [
38] and the perceived usefulness scale by Davis et al. [
52]. Considering the BIM learning context, the learning behavior scale of this study contains 21 items. In addition, a polygraph question is set in the questionnaire: “Please choose the option of completely disagreeing with this question”. If the respondent chooses other options, it is considered that there are some cases, such as choosing directly without reading the questions, and the questionnaire is regarded as invalid. Please see
Appendix A for the detailed questionnaire.
3.3. Sampling and Date Collection
This study conducted a questionnaire survey in March 2022 using random sampling. The process was divided into three steps: choosing the investigation area, schools, and students.
1. Sampling investigation area: In order to make the research data representative and convincing, the sampled universities cover seven geographical regions in China, including northeast China, north China, east China, south China, central China, northwest China, and southwest China.
2. Sampling colleges and universities: Since BIM technology mainly involves AEC-related majors, universities with civil engineering, engineering management, and other construction majors were mainly selected in the school selection process. According to the types of undergraduate colleges in China, at least one university of four types (research-oriented, applied research-oriented, application-oriented, and private research-oriented) was randomly selected from seven geographical regions to ensure that the sample universities cover the seven regions and four types. We also started point-to-point contact with randomly selected universities to ensure their intention to cooperate. Finally, 35 sample universities were determined, including 8 research-oriented universities, 10 applied research-oriented universities, 8 application-oriented universities, and 9 private research-oriented universities. Sampling information of colleges and universities is shown in
Table 2:
3. Sampling students: In this study, online questionnaires were distributed among the students via the teachers from the selected colleges. The research intended to choose at least 30 valid samples in each college, and it was estimated that 1050 valid total samples would be selected.
Data collection mainly went through two stages: the first stage was the pre-investigation stage, which aimed to get feedback to improve the questionnaire quality. This stage started on 20 March and lasted until 26 March 2022. The second stage was the formal investigation stage, which lasted six days, from 27 March to 3 April 2022. The research team contacted AEC-related professional teachers from the selected schools to request they issue online questionnaires. The research team kept tracking and feeding back the questionnaire results, and finally, 1699 questionnaires were collected. A total of 609 invalid questionnaires were eliminated through polygraph questions, and 1090 valid questionnaires were finally recovered with an effectiveness rate of 64.16%.
Among the 1090 valid questionnaires, 455 were male, accounting for 41.7% of the total and 635 were women, accounting for 58.3% of the total population. The interviewees’ age is mainly between 19 and 22 years old, which is also in line with the age group of undergraduate students. In terms of grades, sophomores account for the most, accounting for 33%; juniors for the next, accounting for 27%; freshmen and seniors for the least, each accounting for 20%. First-year students have just entered the university, so they do not know much about BIM technology and other professional technologies. Hence, their intention to fill out the questionnaire was not firm. Moreover, most seniors have entered internship positions, and the samples collected were few.
Table 3 represents the interviewees’ statistics:
5. Discussion
Based on UTAUT theory, this study explores the factors influencing students’ learning behavior toward BIM technology in AEC-related majors. However, it is worth noting that effort expectancy has no significant effect on learning intention.
Firstly, through the verification of BIM technology learning intention and behavior model, we found that learning attitude (β = 0.675,
p < 0.001) has the greatest predictive effect on college students’ BIM technology learning intention, while learning attitude (β = 0.137,
p < 0.001) has a significant indirect impact on learning behavior through learning intention. In this study, among the three observed variables that constitute attitudes, LA2 (I am interested in BIM technology) and LA3 (It is fun to learn BIM technology) have the highest factor loads. It can be seen that when college students are more interested in BIM technology, their intention to learn is higher. This finding is similar to the conclusion drawn by Mohan et al. [
45], manifesting that students are more willing to learn when they think MOOCs are more attractive.
Furthermore, this study also verified that performance expectancy (β = 0.101,
p < 0.001) and social influence (β = 0.144,
p < 0.002) have a significant direct influence on college students’ intention to learn BIM technology. In addition, performance expectancy (β = 0.02,
p < 0.001) and social influence (β = 0.029,
p < 0.002) have a considerable indirect influence on learning behavior. If college students think that learning BIM technology is helpful to their studies, job hunting, and career development, they will have a higher learning intention of BIM technology. The higher learning intention will significantly and indirectly influence their BIM technology learning behavior. Research by Choukas-Bradley et al. [
61] shows that young people are easily influenced by their peers. For example, when classmates, teachers, and other people who can influence college students’ behavior think they should learn BIM technology, they will also increase their intention to learn. On the other hand, when college students realize that BIM technology is developing well in the construction industry, it will also effectively enhance their intention to learn BIM technology. The industry and educational circles have been working together to improve BIM teaching, integrating BIM education into AEC courses in universities [
3]. BIM-related courses are obligatory for AEC majors in many universities [
32,
33,
34]. However, before entering colleges and universities, many students have never experienced working with BIM technology, and most of them are exposed to BIM technology at the request of teachers or the recommendation of senior seniors. Under such conditions, the social influence on students will play a great role.
Moreover, facilitating conditions (β = 0.212,
p < 0.001) positively impact college students’ BIM technology learning behavior. When the school supports college students in learning BIM technology, they can get help from teachers or classmates when they encounter difficulties learning BIM technology. As a result, their learning can be improved. For example, research by Ao et al. [
1] showed that the teacher’s guidance significantly positively impacts students’ BIM learning performance. In addition, students’ learning behavior can be positively influenced by facilitating their access to the required resources from the school library or online resources while learning BIM technology.
However, unlike the conclusion of Venkatesh et al. [
38], in this study, effort expectation has no significant influence on college students’ intention to learn BIM technology (β = −0.035,
p > 0.05). This result is surprising because it is inconsistent with most previous research conclusions. For example, the research of Li and Zhao [
39] reflects that effort expectancy is expected to have a significant positive impact on the intention of continuing to use MOOC. VanDerSchaaf et al. [
40] research also shows that effort expectancy and social influence are the key influences on college students’ intention to use information technology to obtain university services. However, the situation of this study is not without precedent. For instance, in the study of influencing factors of doctors’ adoption of electronic health records by Hossain et al. [
41], it was concluded that efforts are expected to have no significant impact on doctors’ adoption of electronic health records. Andrews et al. [
42] found that the effort is expected to have no significant impact on librarians’ adoption of AI and related technologies. This work [
43] suffers the same limitations as social networking sites, and effort expectancy has no significant influence on behavior intention. In the study of Indian graduate students’ intention and obstacles using MOOCs by Mohan et al. [
45], relevant conclusions have also been drawn. Efforts expectancy, social influence, and facilitating conditions have no statistically significant influence on the intention to use MOOCs. In the research of pharmaceutical students’ acceptance of LabSafety based on mobile devices by Ameri et al. [
44], it was also found that effort expectancy has no significant influence on their intention to use. Further analysis shows that there might be two reasons for the insignificant influence of effort expectation on learning intention in this study: First, college students are generally younger (ranging from 19 to 25 years old). Therefore, they can easily accept the new technology, and it is less cumbersome to learn BIM technology since potential hardship in learning new technologies can not affect their intention to learn. Second, only basic software operations are being taught in many schools. Many complex functions have yet to be explored by students. Therefore, it is not clear what efforts are needed to learn BIM technology, and this issue has been mentioned by many students in questionnaire interviews. As shown in the scores of the performance expectancy items, the scores are mainly distributed between “general” and “basic agreement”, which is closer to “general”, and it can be seen that most students do not know much about BIM technology’s performance expectancy or perceived ease of use. In other words, students do not know much about the difficulty of BIM technology. They are only informed about BIM technology’s capabilities to obtain better job opportunities, but they do not know exactly how and what to learn. Therefore, some college students’ understanding of BIM technology is still insufficient and there is no significant statistical relationship between their expectation and intention to learn BIM technology.
6. Conclusions and Implications
Through sorting out and analyzing a large number of related literature works, this study uses UTAUT to construct the model of influencing factors of BIM technology learning intention and behavior from the perspective of students’ perceptions. A random sample questionnaire survey was conducted among AEC majors in four types of universities (research-oriented, applied research-oriented, application-oriented, and private research-oriented) in seven regions of China (northeast, north, east, south, central, northwest, and southwest), and the influencing factors and their relationships were explored. The results show that, in addition to effort expectancy, performance expectancy, social influence, and learning attitude have significant direct effects on learning intention and have significant indirect effects on learning behavior through learning intention; facilitating conditions and learning intention have significant direct effects on learning behavior. This study once again verified the effectiveness of UTAUT in the field of BIM technology learning and confirmed the significant influence of attitude on BIM technology learning intention and behavior.
6.1. Practical Implications
Based on the research conclusion, this study puts forward the following suggestions for further improving the BIM technology education for college students:
1. Given the significant positive influence of learning attitude on learning intention and behavior, the learning objectives of undergraduate students need to be clarified to improve the learning attitude towards BIM technology. Therefore, to make students’ learning objectives clear, the curriculum arrangement in colleges and universities should include basic knowledge of BIM and career planning. In this way, first-year students can overcome their fear of ignorance of BIM industry. Moreover, a well-established BIM curriculum may assist students in realizing the importance of BIM technology to the future of AEC industry.
2. Because of the significant positive influence of facilitating conditions on learning behavior, the BIM technology training for teachers should be strengthened to improve BIM technology operation and teaching ability. The more the teachers are capable of teaching BIM technology, the more support they can provide for the students. Thus, the improvement of teachers’ professional skills will be beneficial to BIM technology education. At present although, college teachers are primarily the young generation with scientific solid research abilities, their teaching ability is generally not enough due to the limitation of working time and experience [
62]. Therefore, college teachers must carry out teaching skills training to improve their professional quality.
3. Given the significant positive influence of facilitating conditions on learning behavior, resources and support for learning BIM technology ought to be enhanced. The leading exporters of BIM talents, colleges, and universities should provide comprehensive support for the application of BIM technology from the aspects of system, human resources, funds, and policies [
63]. In addition to ensuring the quality of BIM courses taught in schools, colleges, and universities, those organizations should encourage and support students to participate in various BIM competitions to improve undergraduate students’ BIM application ability. This suggestion may lead to continuously training qualified AEC graduates for the industry.
4. In view of the significant positive influence of social influence on learning intention and behavior, the promotion of BIM industry and the creation of BIM learning and application atmosphere are vital. The higher the industry adoption of BIM technology, the stronger the willingness of college students to learn. Hence, the government should provide policy and economic support to enterprises, encourage the construction industry to apply BIM technology, and actively promote BIM technology, creating a solid learning atmosphere for BIM technology educators and learners.
6.2. Future Work
This study adopts the UTAUT model, which has a very high degree of explanation for user intention and behavior. However, the model does not consider individual students’ learning abilities and methods. Future directions of work focus on adding constructivist learning theory and considering learning self-efficacy on this research basis. In addition, considering that too many questions in the online questionnaire may seem boring for respondents, the number of questionnaire items is relatively small. However, fewer items in each latitude may make deeper content impossible to explore. In the following research, each dimension can be further subdivided in detail, and additional items can be added to make the measurement results more accurate.
