ABSTRACT
The purpose of this study is to apply the Technology Acceptance Model to
identify the determinants aecting students’ behavioural intentions when
it comes to using micro-lectures. The conceptual framework included
three antecedents of behavioural intentions – perceived usefulness of
micro-lectures; perceived ease of use of micro-lectures; and user satisfac-
tion. Moreover, the four rst-order constructs of content richness, user
satisfaction, vividness and self-ecacy were incorporated into the frame-
work based on the theoretical construction. Employing a structural equa-
tion modelling approach, the hypothesised model was validated
empirically using data collected from China. This study examines two
factors (perceived usefulness of micro-lectures and user satisfaction in
terms of micro-lectures) related to learners’ behavioural intentions to
continue using micro-lectures. Additionally, micro-lecture compatibility,
micro-lecture self-ecacy and the vividness of micro-lectures emerged as
critical predictors of the perceived usefulness of micro-lectures. The nd-
ings provide practical implications for educators and micro-lecture learn-
ing system developers.

Introduction
During the second decade of the twenty-rst century, massive open online courses (MOOCs) and
small private online courses (SPOCs) (Fox, 2013) have had a major inuence on higher education.
Students can spend considerable time outside of class engaging with self-paced instructional videos
and quizzes, with immediate feedback available 24 hours a day that students can use as frequently as
desired. Interactive technology-based tools allow users to control videos by playing, pausing and
forwarding (Delen et al., 2014). At one time, the instructors in the classroom focused on facilitating
discussion for a deeper understanding of the overall themes of the course. With the development of
digital technology, delivery speed on the part of the network used is gradually growing. David
Penrose, who is the manager of online services at San Juan College in the USA, and also the proposer
of ‘micro-lectures’, came up with the idea that the traditional class-video can be replayed by pieces of
a lecture lasing one minute dealing with specic topics (Shieh, 2009). When the micro-lecture was
introduced to China, its length was often about 5–8 minutes instead of the original 60 seconds.
Besides the length, other aspects of the micro-lecture have also been adapted to t the Chinese
context (Song, 2016). If the content is too long, it will decrease the eectiveness and eciency of
learning (Wilson & Korn, 2007). Accordingly, instructors are doing most of the lectures themselves in
order to avoid disconnecting from the course material. In general, micro-lectures maximise the

leverage of the scarce resource – instructor time – and play an important role in course design with
regard to the support of SPOCs.
As a new form of text representation, attention about how to eciently use the micro-lecture has
continued to grow (Cheng et al., 2017; Mitra et al., 2010). Students can access high-quality materials
and go back to watch them repeatedly if they nd that they have insucient knowledge, in order to
complete the exercises at their own pace. This might enhance learner engagement and so improve
learning eectiveness. Studies on adoption and usage of micro-lectures start from the point where
technology is introduced as an innovation and try to analyse its acceptance and behavioural
intentions during this study. There have been certain studies on student adoption of technology
for learning (Giannakos & Vlamos, 2013; S. Y. Park et al., 2012). These studies have suggested that
students’ acceptance of technology for learning should be predicted and analysed through dierent
factors. These factors include perceived self-ecacy (Lai et al., 2012) for learning, user satisfaction
with a specic learning context (D. Lee & Lehto, 2013), perceived usefulness or awareness of the
educational potentials of technological resources (Davis, 1989; Liaw & Huang, 2013) and technical
support (Sánchez & Huero, 2010). However, none of the theories and models in the usage and
adoption literature could predict behavioural intentions in micro-lecture-based learning environ-
ments. Moreover, the variables that these theories were based on also varied. What is missing in
current literature is a conceptualisation of the complex relationships among these variables and how
they work together to aect behavioural intentions on use of micro-lectures for learning. In order to
gain knowledge of what factors will aect students’ perceptions of micro-lectures in SPOCs, this
study tries to answer two main research questions:
RQ1: Will the three factors of perceived usefulness of micro-lectures, perceived ease of use of micro-
lectures and user satisfaction with micro-lectures inuence students’ behavioural intentions to use
micro-lectures?
RQ2: Will other factors such as the content richness of the micro-lectures, the vividness of the micro-
lectures, and micro-lecture compatibility and micro-lecture self-ecacy inuence students’ percep-
tions of the usefulness of micro-lectures?
Theoretical background
Micro-lectures and SPOCs
The SPOC refers to on-campus lectures using the MOOC technology platform and teaching
methods. SPOC is also known as ‘private lesson’, that is, small private online courses. It is a new
concept proposed by Harvard University after the MOOC (Kaplan & Haenlein, 2016), which limits
numbers of participants. MOOCs and SPOCs are two innovative ways of distance learning con-
ducted online, which dier primarily in the number of participants to which they cater (Kaplan &
Haenlein, 2016). MOOCs are a specic type of provision of online courses without participation
restrictions. SPOCs are online courses that are oered only to a limited number of participants and
therefore require some form of formal enrolment. MOOC technology uses collaborative methods
based on building knowledge with students worldwide to enhance their learning. Universities
could also use this knowledge to reach out to a greater audience through the MOOC. Universities
could also introduce more participative methods on campus through similar environments such as
SPOCs. Universities can implement SPOCs because they represent an innovation in learning
methods, their network presence and students’ enrolment (Freitas & Paredes, 2018). SPOCs allow
teachers to use a ‘blended learning’ approach and ‘ipped learning’ approach that combines
classroom teaching with online learning (Chen & Yang, 2015). Compared with MOOC, micro-

lectures used by SPOC are more attractive than the designated reading materials to prepare
students for their participation, especially for students who are not motivated to learn. Micro-
lectures, such as videos, are the most diversied and distinct virtual learning media. They can assist
traditional classrooms just as projectors and PowerPoints do. The nal purpose of micro-lectures is
to actively encourage student learning based on the learners’ needs and involving new technol-
ogies. Many researchers have explored several issues related to the ease of use, acceptance and
usefulness of dierent e-learning media such as Moodle (Sánchez & Huero, 2010) and other
systems (Ngai et al., 2007). At present, micro-lectures are always used in college teaching for
supporting the ‘ipped learning’ approach, which can meet students’ requirements for individua-
lised learning (Blair et al., 2016; Davies et al., 2013). Empirical analysis of behavioural intention to
use micro-lectures in SPOCs is lacking.
Hypotheses development
The Technology Acceptance Model (TAM), acclaimed for explaining individual behavioural inten-
tions, serves a useful frame of reference when it comes to helping to conceptualise factors that
might inuence users’ acceptance of an information system (Davis, 1989). It has also proved to be
useful in elaborating university students’ adoption or use of new technology for learning (McGill &
Klobas, 2009). The TAM assumes that perceived usefulness (PU) and perceived ease of use (PEOU)
are the key antecedents of behavioural intention (BI) towards using the information technology.
Behavioural intention is ‘the degree in which a user formulates conscious plans to develop or not
a particular future behaviour’ (Warshaw & Davis, 1985, p. 214). The rst key belief, PU, is the degree
to which the user supposes that a technology would improve his/her job performance (Davis,
1989). PU has consistently been shown to be the strongest predictor of continuance behaviour in
variance contexts (Hartshorne & Ajjan, 2009; Lee et al., 2013). PEOU, the second key belief, refers to
the degree to which the particular technology is free of eort (Davis, 1989). Previous studies show
that PEOU has a positive eect on users’ behavioural intention to use systems (Sharma & Chandel,
2013; Teo, 2010). Thus, we include PU and PEOU as important predictors in our theoretical
framework.
Hypothesis 1: Students’ perceived usefulness positively inuences their behavioural intentions with
regard to using micro-lectures.
Hypothesis 2: Students’ perceived ease of use positively inuences their behavioural intentions to
use micro-lectures.
However, at the same time, a variety of previous studies have reformed the original version of the
TAM by reinterpreting the underlying structures of some constructs in terms of the particularities of
the educational context (Chen, 2011; Lai et al., 2012). TAM2 incorporates several other theoretical
factors, including social inuence process and cognitive instrumental processes (Venkatesh & Davis,
2000). The TAM was further extended to incorporate another variable – user satisfaction (D. Lee &
Lehto, 2013). Ives et al. (1983) indicated that user satisfaction is the user’s opinion of the system and
that the capacity of the system should enhance the user’s power to make decisions. When used in
this study, satisfaction is usually conceptualised as the important construct aecting the success of
a learning system (Shee & Wang, 2008; Wu et al., 2010). A higher level of satisfaction towards
a system indicates a higher degree of willingness to use it (Liaw & Huang, 2013). M. C. Lee (2010)
identied that students’ continuance intention to learn is greatly inuenced by their satisfaction.
Therefore, we present the following hypothesis:
Hypothesis 3: User satisfaction positively aects behavioural intentions with regard to micro-
lectures.
TECHNOLOGY, PEDAGOGY AND EDUCATION 3
Further, researchers have studied contextual factors that aect the perceived usefulness of
a particular new technology. Content richness is operationally dened here as a large amount of learning
resources that learners can access to enrich their learning activity (D. Lee & Lehto, 2013). Generally,
measuring content richness or similar concepts (i.e. information quality, Tung & Chang, 2008) involves
three dimensions: relevance, timeliness and suciency (Jung et al., 2009). In a variety of previous studies,
aspects of content richness such as content quality and information quality (Park et al., 2012) oered by
a system have proven to be a factor that inuences perceived usefulness. Y. C. Lee (2006) noted that
content qualities, which are similar to content richness, were signicant antecedents of perceived
usefulness when using an e-learning system. According to the study by Huang et al. (2017), the
relationship among students’ learning, content richness and vividness was strong. Richness has focused
on the category of the media used to deliver information in traditional studies dealing with media
richness. The user can access this useful information in such a way as to enrich their learning activity.
Steuer (1992, p. 80) described vividness as ‘the ability of a technology to produce a sensorial rich
mediated environment’. Vividness is signicant because it will aect the expression of virtual objects
and the natural combination of virtual objects and real environment. Vividness of the course content
is also especially signicant (Desai et al., 2008) for both educational modes, especially SPOCs,
because, as previously mentioned, students cannot directly and instantly interact with teachers as
they can in traditional face-to-face educational modes, which makes the provision of vivid content of
particular importance. Learner groups in micro-lectures with vivid content in a SPOC system can
communicate through a variety of dierent cues, such as visual (for example, teacher’s gestures in
videos, images) and auditory (teacher’s voice, background music, etc.) cues; they accordingly under-
stand each other better. We posit
Hypothesis 4: Content richness positively aects perceived usefulness.
Hypothesis 5: Vividness positively aects perceived usefulness.
Agarwal and Prasad (1998) modied the TAM by adding the factor of compatibility. In the eld of
information systems (IS), compatibility is considered as one of the basic prerequisites for users to
adopt new technologies or applications (Cheng, 2015). Compatibility is dened as the extent to
which technology ts with potential existing values and experiences (Rogers, 2005). Compatibility is
the intensity with which online learning technology is perceived to be consistent with student
beliefs, values and lifestyles (Ozturk et al., 2016). Students consider online learning systems are more
useful when they believe in their capability of taking online courses successfully (J. W. Lee &
Mendlinger, 2011). In this study, we treated educational compatibility in our theoretical framework
as an important predictor with regard to perceived usefulness.
Hypothesis 6: Compatibility positively aects perceived usefulness.
Agarwal and Karahanna (2000) proposed to modify TAM by adding factors like playfulness, self-
ecacy and personal innovativeness. There is substantial evidence that self-ecacy inuences
competence when it comes to learning and persistence in the face of challenges (Zhu et al., 2011).
Terzis and Economides (2011) considered computer self-ecacy has a causal link with perceived
usefulness. Marakas et al. (2007) suggested that users with high technology self-ecacy were more
likely to perceive higher perceptions of perceived usefulness. This means that students who have
higher self-ecacy are more likely to perceive learning systems as more useful (J. W. Lee &
Mendlinger, 2011). Consequently, the following hypothesis is developed:
Hypothesis 7: Micro-lecture self-ecacy positively aects perceived usefulness.

Thus, in this study, we incorporated some constructs into the existent technology acceptance
model according to the ndings from student technology adoption. The conceptual framework of
this study is presented in Figure 1. The relationships among variables were discussed, and conse-
quently, we developed the hypotheses derived from this discussion.
Methodology
Context of this research
Since 2015, Tianjin University in China has gradually uploaded micro-lectures recorded by its own
teachers to the university’s e-learning platform. Only students in this school with a password can
watch the micro-lectures to ensure privacy. The psychological course was a four-credit course and
was oered during the winter semester. The course dealt with the work responsibilities and role
positioning of psychological committee members that are relevant to the eld of mental health
education work. Before the class, students need to watch four to ve micro-lectures per class for
a total length of almost 30 minutes.
As shown in Figure 2(a), the module listed the structure of the selected course including units,
courseware and activities, which were dened by the teachers. More specically, every course
comprised several units; every unit comprised several pieces of micro-lectures. Figure 2(b) is an
example of a micro-lecture with slides. Then, students were asked to nish the assignments on the
platform after watching the micro-lectures. During the face-to-face class, the students were discuss-
ing in groups for about 45 minutes, and the instructor gave individual guidance to students who
asked questions. After the discussion, students presented major themes of the course and their
shared insights by group presentation. Afterwards, the instructor highlighted and gave a focused
explanation of the complex or controversial issues covered by the course content. Face-to-face
lessons lasted two hours each. Upon completion of the course, students were required to write
a reection document. The reection reported on the role of psychological committee members in
identifying students with psychological problems in real life and guiding students to seek profes-
sional teachers’ help.
Participants
The survey was carried out at the beginning of the second semester, in the school year 2016–17. Not
all Tianjin University students attend SPOCs. A signicant criterion for selecting the participants was
that they had attended some courses involving micro-lectures in the past. In sum, 285 individual

surveys were returned. However, incomplete responses and inappropriate responses that featured
uniform answers to the entire set of questions were excluded. A total of 202 fully answered
responses were used for the analysis (Table 1), including 125 (61.9%) males and 77 (38.1%) females.
Approximately 82.2% of the participants had one to two courses involving the use of micro-lectures.
Each course consists of several micro-lectures. A majority of the participants (95.5%) were working
towards a bachelor’s degree and ranged in age from 18 to 23.

Instruments
The questionnaire consisted of two parts: (1) questions concerning the demographics of the
participants; and (2) measures of antecedents aecting the behavioural intentions to use micro-
lectures in SPOCs. The second part of the survey instrument was adapted from previous studies (D.
Lee & Lehto, 2013; Liaw, 2008; Taylor & Todd, 1995). The 27 adjusted items were carefully modied to
t the context of this study (see Appendix). Measurements for PEOU and PU of the micro-lectures
were based on Davis (1989), Lai et al. (2012) and Venkatesh et al. (2002), and with semantic
dierential scale of four items in the PU latent variable and semantic dierential scale of three
items in the PEOU latent variable. Measurement for the user satisfaction of the micro-lectures was
based on Liaw (2008), with semantic dierential scale of four items. Measurement for the BI to use
micro-lectures was adapted from Lee et al. (2011), with semantic dierential scale of four items.
Measurement for the content richness of the micro-lectures was based on D. Lee and Lehto (2013),
with semantic dierential scale of four items. Measurement for the user satisfaction of the micro-
lectures was based on Liaw (2008), with semantic dierential scale of four items. Measures of
vividness of micro-lectures and micro-lecture compatibility consist of ve items. The two items for
the vividness construct were adapted from Jiang and Benbasat (2007). The three items for the
compatibility construct were adapted from Taylor and Todd (1995). The three items for the micro-
lecture self-ecacy were based on Zhao et al. (2010). All items were assessed using a 5-point Likert
scale with anchors ranging from 1 (= not at all true) to 5 (= very true).
Data analysis
Amos 20, a software package designed to perform a structural equation model (SEM) approach to
path analysis, was used to test the hypothesised relationships of the full structural model. Sample
size requirements for structural equation models are at least 200 cases (Kline, 2011). Given that the
sample of the present study consists of 202 people, it can be said that the present study has
a reasonable sample size. Analyses started with correlation analyses to investigate the strength of
the relationships between PU, PEOU, US and BI, and then relationships among PU and other
predictor variables.
Results
Descriptive statistics of the measurement instruments
The descriptive statistics of mean and standard deviation were calculated for the constructs and the
items measured (see Table 2). The means of all the constructs were rated above 3.0 on the one-to-
ve scale, ranging from 3.20 (Compatibility: SD = 1.07) to 3.42 (Micro-lecture self-ecacy: SD = 1.10).
Among the constructs, the compatibility of micro-lectures is the lowest (Mean = 3.20, SD = 1.07),
while the highest is micro-lecture self-ecacy (Mean = 3.42, SD = 1.10). The means of items ranged
from 3.10 (BI2, SD = 1.17) to 3.45 (US2, SD = 1.13). Skewness and kurtosis were examined to conrm
the normalised distribution of the collected data.
Analysis of the measurement model
The Cronbach’s alpha scores, shown in Table 3, indicate that each construct exhibited strong internal
reliability. Convergent validity can be established based on the criterion that two similar indicators
correspond with one another. Convergent validity was evaluated based on Fornell and Larcker's
(1981) criteria: all indicator factor loadings (k) should be signicant and exceed 0.5, and average
variance extracted (AVE) by each construct should exceed 0.5. All standard factor loading (k) values in
conrmatory factor analysis of the measurement model exceed 0.5 (from 0.70 to 0.85), and the AVE,
ranging from 0.501 to 0.712, was greater than the variance because of measurement error. In
TECHNOLOGY, PEDAGOGY AND EDUCATION 7
addition, composite reliability values of 0.60 to 0.70 are acceptable in exploratory research (Nunnally
& Bernstein, 1994). All composite reliability, in this research, was greater than 0.6, ranging from 0.667
to 0.883. Consequently, all construct met the requirements for reliability and convergent validity. As

shown in Table 4, discriminant validity was conrmed based on the square root of the AVE statistics;
the values of the square roots of the AVE values are greater than the other values of the inter-
construct correlation.
Analysis of the structural model
Table 5 reports the result of the chi-square to degree-of-freedom ratio of 1.780, goodness-of-t index
(GFI) of 0.854, adjusted goodness-of-t index (AGFI) of 0.801, comparative t index (CFI) of 0.963,
normed t index (NFI) of 0.921 and root mean square error of approximation (RMSEA) of 0.062. Doll
et al. (1994) suggested that the value of GFI and AGFI is acceptable if above 0.8. Therefore, the overall
statistics reveal a moderately acceptable t model.
Hypotheses examination
The results of the SEM analysis are illustrated in Figure 3. Two variables of perceived usefulness of
micro-lectures and user satisfaction in term of micro-lectures together accounted for 65.4% of the
variance in inuencing students’ behavioural intentions to use micro-lectures. In this study, three
hypothesised associations were strongly signicant at p < 0.001, two hypothesised associations were
signicant at p < 0.01, and hypothesis 2 and hypothesis 4 were not signicant. Consistent with H1
and H3, perceived usefulness of micro-lectures was positively related to behavioural intention to use
micro-lectures (β = 0.233, p < 0.001) and user satisfaction in terms of micro-lectures (β = 0.563,
p < 0.001) was positively related to behavioural intention to use micro-lectures. Based on the result, it
was found that the perceived usefulness and user satisfaction aect the behavioural intention to use
micro-lectures. Similar to a previous study conducted by Liaw (2008), user satisfaction was found to
be the factor that inuences students’ behavioural intention to use micro-lectures the most highly.
Nevertheless, the impact of perceived ease of use of micro-lectures on behavioural intention
(Hypothesis 2) was not supported (β = 0.402, p > 0.05). Therefore, the user’s behavioural intention
to use micro-lectures is not directly aected by perceived ease of use. Regarding H5–H7, vividness
was positively related to perceived usefulness (β = 0.233, p < 0.001), compatibility was positively
related to perceived usefulness (β = 0.233, p < 0.001) and micro-lecture self-ecacy was positively
related to perceived usefulness (β = 0.233, p < 0.001). These three predictors explained 72.1% of the
total variance in perceived usefulness. This emphasises the importance of management considering

Discussion and conclusions
The role of perceived usefulness, perceived ease of use and user satisfaction in inuencing
behavioural intentions
Except for perceived ease of use, all path coecients were found to be statistically signicant.
Consistent with our predictions, the students’ perceptions of usefulness were found to be a direct
predictor of their behavioural intentions. Perceived usefulness has found to be an extrinsic motivator
when it comes to determining students’ behavioural intentions in many educational environments
(Lai et al., 2012; Nazarenko, 2015). The present study contributes to the knowledge community by
investigating the impact of perceived usefulness of micro-lectures on the behavioural intention to
use micro-lectures. In the SPOC environment, students appreciated accessible resources that meet
their needs. This is probably closely related to the fact that students are likely to use resources to
achieve their specic learning goals. This could be primarily true amongst university students since
they can benet from wide and easy access to the resources used in the learning process. D. Lee and
Lehto (2013) did similar research to investigate users’ acceptance of YouTube for procedural learning
by introducing TAM. They indicated that perceived usefulness can be an extrinsic motivator when it
comes to determining learners’ behavioural intentions when they use YouTube in order to achieve
their specic learning goals.

In the hypothesised model, the present study conrms the claim that behavioural intention to use
micro-lectures was signicantly predicted by user satisfaction in terms of micro-lectures. This partly
varies from previous studies (see, e.g. Davis, 1989) which indicate that the constructs of usefulness
and ease of use have a direct inuence on intentions concerning technology. It seems that user
satisfaction is typically treated as the evaluation of the emotion based on the outcomes associated
with the system and cannot shape the initial users’ acceptance. However, Dalcher and Genus (2003)
reported that end-user satisfaction was depicted as a likely eect on acceptance and, subsequently,
increased usage. Actually, user satisfaction with a single system can be asserted as the most
signicant determinant of long-term foundation intention to use the system (Bhattacherjee, 2001).
In the present study, even though students could use micro-lectures with satisfaction at rst for
some reasons (e.g. novelty eects), since the use of systems with the target behaviour is mandatory
(Baroudi et al., 1986), they will not continue to use micro-lectures when they are dissatised with
them (Joo et al., 2017). When students have an alternative system choice, user satisfaction is
a reliable measure of the behavioural intention to use micro-lectures, because user satisfaction is
viewed as a perceptual or subjective measure of system success which will inuence intrinsic
motivation, commitment to learning and learning performance (Shee & Wang, 2008; Wu et al.,
2010). The ndings suggest that educators should be aware of the distinctiveness of user satisfaction
in continuing to use micro-lectures. Users’ behavioural intentions can be better predicted by the
integration of user satisfaction and TAM, the predictive power of user satisfaction can be improved
and the utility of TAM can be augmented.
However, contrary to conventional predictions from TAM, perceived ease of use was found to be
unrelated to the behavioural intention to use micro-lectures. Past research has discussed the weak
role of perceived ease of use in predicting user acceptance (Wang et al., 2009). For example, in
a study of user acceptance of YouTube for procedural learning (D. Lee & Lehto, 2013), the authors
noted that participants did not give much priority to retaining their perception of ease of use when
making acceptance decisions. This means that in most cases, students tend to have the inclination to
use micro-lectures directly, rather than thinking about their perceived ease of use. In the present
study, a sensible explanation for the insignicant nding may be that using micro-lectures does not
create a practical barrier to acceptance given that the students involved had experienced some
micro-lectures. They have control over the skills in taking micro-lectures and will not be frustrated
and discouraged by using them. Consequently, most students may not need to think and ponder
once they want to look for something. For example, when they browse a website to watch some
micro-lectures, they will usually nd it immediately due to a specic link to it. Similarly, over time,
Internet technology is increasingly becoming user-friendly and accessible. Experienced students can
watch online lectures they need to watch with just a click of mouse.
Factors aecting students’ perception of usefulness of micro-lectures
The TAM and its evolutions show the importance of four additional variables including content
richness, vividness, compatibility and micro-lecture self-ecacy as moderating variables of perceived
usefulness. The result of this research support previous research, suggesting that perceived useful-
ness could be inuenced by vividness, compatibility and micro-lecture self-ecacy (Hernandez,
2011; Lai et al., 2012). In particular, increased levels of vividness were found to increase perceived
usefulness. However, this is dierent from a previous study where content richness emerged as
a signicant predictor (De Wulf et al., 2006). In this study, content richness failed to demonstrate
a signicant eect on perceived usefulness. This nding is partly in line with the work of Huang et al.
(2017), which indicates that content richness is less likely to help students learn if the course is
complex. The more complex a course is perceived by students, the less powerful the eect of course
content richness is on their intention to revisit. With respect to the nature of dierent courses (i.e.
diculty level of the course content), the ndings suggest further that course diculty negatively
aects the relationship between the richness of course content and students’ perceived usefulness.
TECHNOLOGY, PEDAGOGY AND EDUCATION 11
In this regard, institutions and educators should simplify the content of micro-lectures only by clearly
teaching a concept, a formula, an example or an experiment.
The study examined the antecedent variables that predict experienced students’ behavioural
intentions when it comes to using micro-lectures in small private online courses based on the
Technology Acceptance Model. The results showed user satisfaction is one of the most signicant
determinants of students’ behavioural intentions to use micro-lectures for learning, and the study
failed to substantiate the eect of content richness on perceived usefulness. These ndings may
have practical implications for organisational planning when it comes to designing and implement-
ing SPOCs involving micro-lectures. One of the limitations of this study is that there is a low level of
participation in the survey. Besides, it would be interesting to see if any dierences are seen between
male students and female students. Another limitation is the missing consideration of other vari-
ables, such as social norms. Future research may need to add other measurements to explain better
technology acceptance and draw more reliable conclusions. Furthermore, detailed discussion of
TAM, course contents, learners’ tasks and instructional strategies can be done in future research.
