    There is a substantial increase in the utilization of web-based assessment procedures to assist teaching

    and learning processes in higher education institutions. Despite their benets, institutions use them to a

    limited extent due to a number of factors inuencing both instructors' and students' behaviors. This

    study examines students' acceptance of a web-based summative listening test administered in the 2014

    e2015 academic year within an English as a Foreign Language' course at a two-year post-secondary

    military school in Turkey. The participants consisted of 602 military students. As a model, Computer

    Based Assessment Acceptance Model based on Technology Acceptance Model was adopted in order to

    analyze the participants' perceptions on a web-based summative listening comprehension test. The data

    were collected via an online questionnaire. A structural equation modeling analysis was utilized to

    analyze the relationships among factors. The general results showed that perceived ease of use and

    perceived playfulness had a direct inuence on the participants' behavioral intentions to use web-based

    tests. In other words, web-based tests are expected to be used if they are easy to use and playful enough.

    1. Introduction

    Seeing that students' frequent use of computers andthe Internet

    is increasing rapidly, web-based testing (WBT) is also becoming a

    prevalent system as an alternative to traditional assessment prac-

    tices in all educational settings around the world. WBT is related to

    the conceptualization and administration of assessments as a so-

    phisticated way of using web technologies (Cigdem & Oncu, 2015)

    with the aim of expanding educational assessments in universities,

    schools or other industry. WBT's becoming widespread resides in

    the fact that an increasing number of faculty members have started

    to realize the convenience of creating, implementing, and man-aging assessment as parts of learning management systems

    (Llamas-Nistal, Fernandez-Iglesias, Gonzalez-Tato, & Mikic-Fonte,

    2013). WBT is seen as a noteworthy method for instructors, espe-

    cially regarding high-stake tests, because it aims to optimize the

    goals and techniques of teaching and testing in shorter times (Pino-

    Silva, 2008) and the delivery or administration of the assessment is

    not supposed to be at a xed time or place (Cigdem& Oncu, 2015;

    Jeong, 2014).

    There have been numerous advantages of WBT for both test-

    developers and test-takers such as exibility of time and place;

    enhanced resource use; immediate and real-time feedback; high

    interaction with test-takers; quick results and real-time score re-

    ports; automated grading and reporting; easier data management;

    cost reduction; more productive managing, organizing, and

    deploying of exams; time-saving evaluation of learners' strengths

    and weaknesses; and learners' self-evaluation (Abedi, 2014; Bull &

    McKenna, 2004;Chou, Moslehpour, & Huyen, 2014; Cigdem & Tan,

    2014; Llamas-Nistal et al. 2013; Morris, 2008; Terzis, Moridis, &

    Economides, 2013; Zakrzewski&

    Steven, 2000). Along with suchadvantages, an effective WBT system is required to provide

    authentic assessment activities and meaningful feedback as well as

    to support multidimensional perspectives (Gikandi, Morrow, &

    Davis, 2011).

    As test developers and test takers are being immersed in WBT

    systems, a greater number of educational researchers tend to work

    on the acceptance of WBT systems with the purpose of dening the

    variables that might explain the acceptance issue. Users' perceived

    acceptance of a technology or behavioral intentions to use a tech-

    nology have been studied and described by many researchers

    previously as in the Theory of Reasoned Action (TRA) (Ajzen &

    Fishein, 1980); the Theory of Planned Behavior (TPB) (Ajzen, 1991);

    the Technology Acceptance Model (TAM) (Davis, Bagozzi, &

    Warshaw, 1989); the Unied Theory of Acceptance and Use of

    Technology (UTAUT) (Venkatesh, Morris, Davis, & Davis, 2003); and

    the Computer Based Assessment Acceptance Model (CBAAM)

    (Terzis &Economides, 2011). Considering the scope of the current

    research, the CBAAM was adopted and studied with the aim of

    determining the students' intentions to use a WBT system in the

    case of a summative assessment of Listening Comprehension in

    English.

    2. Literature review

    As the researchers have been driven to examine the factors that

    affect user's perceptions on the adoption and acceptance of WBT

    systems, there has been a considerable amount of literature por-

    traying the application of the CBAAM in various educational con-

    texts. To exemplify, Dermo (2009) surveyed 130 undergraduate

    students participating in an online (formative/summative) assess-

    ment system during the 2007e2008 academic year and found that

    the reliability, security, validity, and accessibility of the system were

    accepted by the participants coming from different academic pro-

    grams like management, informatics and engineering, life sciences,social sciences and education, and therefore learning was promoted

    among them. As another example, Terzis and Economides (2011)

    worked on the perceptions of introductory informatics course

    students on the acceptance of WBT. Their results indicated that

    perceived ease of use and perceived playfulness had a direct effect

    on the use of computer-based assessments, whereas perceived

    usefulness had only an indirect effect. In Sorensen's (2013)survey

    on students' perceptions about e-assessments in a college chem-

    istry course, the participants thought that e-assessment facilitated

    their learning. With that study, more frequent implementations of

    e-assessment in other courses was also suggested. In a study con-

    ducted with military students at a Mathematics course, it was seen

    that students having computers and the Internet at home as well as

    prior web-based exam experiences were more optimistic about thecomputer-based assessments than the other students (Cigdem &

    Tan, 2014). In another survey done with military students,

    Cigdem and Oncu (2015) investigated perceptions on WBT in a

    computer networks course and found that the contents of the

    questions signicantly affected perceived usefulness and that

    perceived usefulness had a great inuence on users' behavioral

    intentions.

    All those attempts reveal that an increasing number of educa-

    tional settings adopt or use WBT systems to deliver and manage

    their assessment procedures more efciently and more conve-

    niently. Since language testing is one of those settings, this study

    investigates the factors that are likely to inuence learners in-

    tentions to use WBT systems in the assessment of their listening

    comprehension. Even though WBTsystemsare thought to be usefulin the realm of language testing, whether such systems are

    preferred over paper-pencil assessment procedures is not clear

    enough (Pino-Silva, 2008). Therefore, the current study is thought

    to be an important step to look into the perceptions of the students

    on WBT systems when assessing a fundamental skill of language

    education, which is listening comprehension.

    3. Signicance of the study

    Turkish educational system is trying to raise generations who

    can speak at least one foreign language, which is frequently English,

    to be able to internationalize its institutions and citizens, and thus

    promote language teaching at all levels of education, particularly in

    higher education. Having graduates who can understand and speak

    English is one of the primary policies of many higher education

    institutions. This fact makes language teaching and testing in

    higher education a difcult and demanding task. Although teaching

    the skills of reading and writing are managed to some extent in

    current implementations, there is still a limited competence in

    teaching and testing of listening and speaking skills. An important

    attempt is thought to carry out a computer assisted system to

    expand teaching and testing of such skills to be able to make it

    more practical and widespread. From this point forth, this study

    will be a good basis for the upcoming value of teaching and testing

    of listening comprehension through technology in higher educa-

    tion. Although the major contribution of the study was to look into

    the variables inuencing the students' intentions to use a WBT

    system, this study aimed to contribute to the eld through an

    attempt to implement a WBTsystem within the context of a foreign

    language course, in particular for an underestimated sub-skill,

    which is Listening Comprehension. Various forms of WBT systems

    were adopted previously in various content areas; yet, such studies

    were limited in number and scope for language teaching contexts.

    Apart from this, the current research setting, which is a unique

    post-secondary higher education institution among its types, adds

    to the signicance of the study.

    4. Research model and hypotheses

    Computer Based Assessment Acceptance Model (CBAAM) was

    proposed byTerzis and Economides (2011)on the basis of previous

    acceptance models such as TAM, TPB and UTAUT as well as with the

    inclusion of additional variables in order to describe behavioral

    intention to use a WBT system. Eight variables were included

    within the model: perceived usefulness, perceived ease of use,

    computer self-efcacy, social inuence, facilitating conditions,

    perceived playfulness, content, and goal expectancy. On the whole,

    Perceived Usefulness and Perceived Ease of Use were adopted from

    the TAM (Davis, 1989); Computer Self Efcacy was adopted from

    Social Cognitive Theory (Compeau & Higgins, 1995); Perceived

    Playfulness was adopted from an extended TAM version byMoonand Kim (2001); and Facilitating Conditions and Social Inuence

    were adopted from the UTAUT (Venkatesh et al., 2003). Apart from

    those, two more variables,Goal Expectancy, which is rooted in Self-

    Management of Learning (Wang, Wu, &Wang, 2009) andContent

    were introduced byTerzis and Economides (2011)to the model.

    As illustrated in Fig.1, the CBAAMsuggests that users' intentions

    to use a WBT system is directly linked to perceived ease of use,

    perceived playfulness, perceived usefulness, and content of web

    based test. Apart from those links, perceived ease of use is dened

    by computer self-efcacy and facilitating conditions; whereas

    perceived playfulness is dened by perceived usefulness, goal ex-

    pectancy, and content of web based test. On the other hand,

    perceived usefulness is also inuenced by social inuence, goal

    expectancy, and content of web-based test.

    4.1. Perceived playfulness (PP)

    Moon and Kim (2001)offered Perceived Playfulness (PP) in the

    TAM, as a key belief constructed through an individual's personal

    experience with a system, Perceived Playfulness (PP) is dened as

    the pleasure the individual feels objectively when committing a

    particular behavior or carrying out a particular activity. PP, as a

    signicant variable, is attributed to have a positive impact on

    behavioral intention to accept and use the Internet or a WBT system

    (Moon &Kim, 2001; Terzis & Economides, 2011) and determined

    by the aspects of concentration, curiosity, and enjoyment (Terzis &

    Economides, 2011). In this framework, it is about the arousal of an

    individual's enjoyment, cognitive curiosity, and concentration

    H. Cigdem et al. / Computers in Human Behavior 61 (2016) 522e531 523

    3/10

    during an activity. Our hypothesis for the current concept was as

    follows:H1. PP would have a positive effect on the Behavioral Intention to

    use WBT.

    4.2. Perceived usefulness (PU)

    As one of the important factors introduced within the TAM,

    Perceived Usefulness (PU) is dened as the level that a person

    thinks using a certain system would enhance his/her job perfor-

    mance within an organizational content(Davis, 1989, p. 320) and

    as the degree to which an innovation is perceived as being better

    than its precursor (Rogers, 2003). PU was found tobe a strong factor

    directly inuencing the behavioral intention to use a technology in

    various educational research contexts (Cigdem & Oncu, 2015; Ong& Lai, 2006; Sun, Tsai, Finger, Chen, & Yeh, 2008; Van Raaij &

    Schepers, 2008; Venkatesh &Davis, 2000). In this sense, a useful

    WBT is attributed to increase perceived playfulness (Terzis &

    Economides, 2011). Therefore, we hypothesized:

    H2. PU would have a positive effect on the Behavioral Intention to

    use WBT.

    H3. PU would have a positive effect on PP.

    4.3. Perceived ease of use (PEU)

    Perceived Ease of Use (PEU), which is dened as the degree to

    which a person believes that using a particular system would be

    free of effort (Davis, 1989; Rogers, 2003), is the second major

    variable of the TAM (Davis, 1989). A lot of research put forward

    evidences on the positive impact of the PEU on behavioral inten-

    tion, perceived usefulness and perceived playfulness (Terzis &

    Economides, 2011; Venkatesh, 1999; Venkatesh &Davis, 1996). In

    this context, as the level of PEU regarding an e-learning system

    increases, the acceptance and use of that system by the participants

    is most likely to increase (Teo, Lee, &Chai, 2008). In this line, we

    had the following hypotheses:

    H4. PEU would have a positive effect on the Behavioral Intention

    to use WBT.

    H5. PEU would have a positive effect on PU.

    H6. PEU would have a positive effect on PP.

    4.4. Computer self-efcacy (CSE)

    Explained as an individual's feelings of his/her ability to use

    computers (Compeau & Higgins, 1995), Computer Self Efcacy

    (CSE) was claimed to have a direct effect on PEU and an indirect link

    to the behavioral intention (Terzis & Economides, 2011). Building

    on this claim, we also hypothesized:

    H7. CSE would have a positive effect on PEU.

    4.5. Social inuence (SI)

    Integrated into the CBAAM as a variable from the UTAUT (Teo,

    2009; Teo et al., 2008) and used in the LMS acceptance models

    frequently (Van Raaij &Schepers, 2008; Wang et al., 2009), Social

    Inuence (SI) is related to individuals' beliefs of how they areinuenced by the opinions and judgments of their colleagues,

    friends, family members, and superiors (Fishbein & Ajzen, 1975;

    Taylor & Todd, 1995; Venkatesh et al., 2003). SI was measured

    through three key variables: Subjective Norm, Image and Volun-

    tariness (Karahanna& Straub, 1999; Venkatesh et al., 2003). SI was

    claimed to be one of the major determinants explaining behavioral

    intention within certain acceptance models like TAM2 and UTAUT

    and to have a positive effect on PU in LMS and WBT contexts (e.g.

    Cigdem & Topcu, 2015; Terzis & Economides, 2011; Wang et al.,

    2009). Although a signicantly positive effect of SI only on PU

    was found within the CBAAM, SI was said to determine users'

    behavioral intentions indirectly through PU (Terzis & Economides,

    2011). Our hypothesis for this concept was as follows:

    H8. SI would have a positive effect on PU.

    4.6. Facilitating conditions (FC)

    Facilitating Conditions (FC) was also adopted from the UTAUT

    (Teo, 2009; Teo et al., 2008) and used in the LMS acceptance models

    (Van Raaij & Schepers, 2008; Wang et al., 2009). FC represents a

    variety of factors that possibly inuence a person's perceptions to

    execute a course of action and depends on the system itself and its

    providers. FC might stand for technical support such as helpdesks

    and online support services; resource factors such as time and

    money (Lu, Liu, Yu, & Wang, 2008); policies, regulations, and legal

    environment of a system; communication activities and active

    participation of organizational staff (Bueno &

    Salmeron, 2008).

    4/10

    Within the scope of the current research, FC was set to cover all the

    support provided by the staff during the WBT and hypothesized to

    have a positive effect on PEU.

    H9. FC would have a positive effect on PEU.

    4.7. Goal expectancy (GE)

    The signicance of the concepts like self-direction, self-man-

    agement, self-discipline, goal orientation, and personal outcome

    expectations (Smith, Murphy, & Mahoney, 2003; Yi & Hwang,

    2003; Shih, 2008) has been mentioned in previous studies. Based

    on Self-Management of Learning (Wang et al., 2009), Goal Expec-

    tancy (GE) occurs as a variable inuencing individuals' beliefs that

    they are prepared appropriately to use a WBT through two di-

    mensions: learners' satisfaction with their preparation for the WBT

    and their desirable level of success. Goals, either specic or difcult,

    serve a purpose towards high performance. Sometimes, greater

    achievements come with more difcult goals. Therefore, it might

    notbe a good strategy forinstructorsto include easy assignments to

    support learning experiences as loss of interest in the course or

    even dropouts might occur as a result (Locke, 1996; Locke &

    Latham, 1990). In a summative assessment within the scope of

    the CBAAM, a positive effect of GE on PU and on PP was demon-

    strated. In this framework, our hypotheses were:

    H10. GE would have a positive effect on PU.

    H11. GE would have a positive effect on PP.

    4.8. Content (C)

    Students are able to learn concepts and improve their perfor-

    mances by answering sample practice questions on each concept

    and taking continuous feedback on their responses (Moreno &

    Mayer, 2007; Tennyson, 1980; Tennyson & Buttrey, 1980).

    Learning concepts could depend on learners' attributes and theirprior knowledge (Tennyson & Park, 1980). Referring to the learners'

    conceptualizations of the content of the WBT, Content (C) was also

    adapted as a variable from previous studies tot in the WBTcontext

    (Shee & Wang, 2008; Wang, 2003). The items of WBT system were

    based on EFL course content. If items in WBT were clear, under-

    standable and relevant to the course content, then it was more

    likely to expect utility and satisfaction by students (Terzis &

    Economides, 2011). It was indicated that C could inuence

    perceived usefulness (Cigdem & Oncu, 2015), goal expectancy,

    perceived playfulness, and behavioral intention to use a WBT sys-

    tem (Terzis & Economides, 2011). Besides, it appeared as a signi-

    cant variable to determine e-learners' satisfaction (Wang, 2003). In

    the light of all those points, we had the following hypotheses

    regarding the Content:

    H12. C would have a positive effect on PU.

    H13. C would have a positive effect on PP.

    H14. C would have a positive effect on GE.

    H15. C would have a positive effect on the Behavioral Intention to

    use WBT.

    5. Method

    5.1. Research context and participants

    This study was conducted in a compulsory EFLcourse taught at a

    post-secondary military school and with 1986 military students

    from various academic programs. Although all the students

    participated in the assessments, only 602 of them responded to the

    online questionnaire.

    Among those 602 students, 65 of them were from the depart-

    ment of Computer Technology, 265 from the department of Elec-

    tronics and Communication Technologies, 133 from the department

    of Business Administration, 33 from the department of Electrics, 70

    from the department of Mechatronics, and 36 from the department

    of Construction. The participants' age ranged from 17 to 23 with an

    average of 19.65.

    The participants had two distinct listening tests. In the rst one,

    they were provided with 20 multiple-choice items and the mean

    value for all the student groups was 62 out of 100. The second one

    included a variety of tasks through 15 items such as drag and drop,

    ll-in-the gaps, matching, and multiple-choice types (see Fig. 2).

    The overall score of this test was not as high as the rst one (M 45

    out 100).

    5.2. Data collection instrument

    The data were collected quantitatively through an online

    questionnaire uploaded on the learning management systemwhere the students are supposed to take their end-of-semester

    listening comprehension exams. The questionnaire included 24

    ve-point Likert-type items which were adapted from the TAM

    literature and administered in Turkish. Table 1 displays the cate-

    gories within the scale and the items within each category except

    for the items excluded from the analyses as they indicated poor

    factorial loadings (i.e.

    measurement model tted the data set well. The nal model with

    the estimated factor loadings is illustrated in Fig. 3.

    In CFA, Composite Reliability (CR), Average Variance Extracted

    (AVE), Maximum Shared Squared Variance (MSV) and Average

    Shared Square Variance (ASV) were examined. According to Hair

    et al. (2010), high (above 0.70) CR values indicate a good reli-

    ability. Table 2 shows that the CRof all the constructs of CBAAM was

    found to be higher than 0.70 and the AVE of all the constructs of

    CBAAM was found to be higher than 0.50. Next, convergent validity

    and discriminant validity were examined. AVE being 0.50 or higher

    indicated a good convergent validity. By using the methods rec-

    ommended byFornell and Larcker (1981), the discriminant validity

    was also tested; by imputing AMOS's correlations and standardized

    regression tables into the validity testing tool within the Stats Tools

    Package'(Gaskin, 2012).

    Table 2shows that discriminant validity thresholds (MSV< AVE,

    ASV < AVE), are realized for all constructs, indicating acceptable

    discriminant validity.

    6.2. Test of the structural model

    After ensuring the validity of the constructs within the mea-

    surement model, the structural model was evaluated. To determine

    the relationship of the constructs in the proposed model, the

    structural equation model was tested using the AMOS 21 with the

    default maximum likelihood estimation method. The model

    returned c2 733.100, df 230; c2/df 3.187 with probability

    level p 0.00 < 0 .05; and RMSEA 0.060, GFI 0.908, and

    AGFI 0.880. All t indices obtained in the present study showed

    good structural model t to the data for the proposed research

    model. The resulting parameters of the research model are dis-

    played inFig. 4.

    Table 3 summarizes the results of our hypotheses. Inspecting the

    model derived from the analyses, it could be claried that there

    appeared a direct positive effect of perceived playfulness andperceived ease of useon the construct of behavioral intention to use

    the WBT systems; whereas perceived usefulness did not exert a

    direct inuence. Along with these points, perceived usefulness and

    content seemed to have a direct positive effect on perceived play-

    fulness; on the other hand, the effects of perceived ease of use and

    goal expectancy on perceived playfulness were not strong enough

    to exert statistically signicant points. On the side of the perceived

    usefulness, goal expectancy did not create any positive effect; yet,social inuence, perceived ease of use, and content each contrib-

    uted to perceived usefulness through a strong impact. Apart from

    these, computer self-efcacy and facilitating conditions both had a

    direct impact on perceived ease of use. Finally, goal expectancy was

    directly and positively inuenced by content.

    7. Discussion

    The major contribution of the current study was to look into the

    variables inuencing the students' intentions to use a WBT system

    in the context of the foreign language education at a two-year post-

    secondary higher education institution. During the study, it was

    attempted to implement a WBT system specically for an under-

    estimated sub-skill, which is Listening Comprehension. Including

    audio les made the design of the listening comprehension test

    through the WBT system even much more difcult and time-

    consuming, compared to other computer-based tests. Students'

    perceptions on the WBT systems were also investigated within the

    scope of thisstudy. To illustrate, the factors within the CBAAMwere

    analyzed descriptively and it was seen that a great majority of the

    mean scores were below the value of 3 and ranged from 1.50 to

    3.59, except for the dimension of computer self-efcacy (see

    Table 1). All those values descriptively indicated that the partici-

    pants had generally negative attitudes towards the WBT systems,which is apparently an inconsistent nding with some previous

    studies (Cigdem& Oncu, 2015; Cigdem & Tan, 2014; Dermo, 2009;

    Sorensen, 2013). It was deduced that students' getting low marks

    from the listening comprehension tests administered through the

    WBT system might have led them to perceive the process

    negatively.

    When the relationships between the variables were investi-

    gated through the SEM, an explanatory model (see Fig. 5) was ob-

    tained. The general results emerging in the model highlighted

    perceived playfulness as the most important determinant of the

    behavioral intention to use the WBT systems and perceived use-

    fulness had only an indirect impact through perceived playfulness.

    This nding was in line with the fundamental proposition of the

    CBAAM.As a parallel nding with Terzis and Economides (2011), the

    results of the current study also indicated that perceived usefulness

    did not exert a direct impact on behavioral intention; however, this

    nding was controversial with the TAM literature, because some

    prior studies (Cigdem & Oncu, 2015) suggested a very strong effect

    of perceived usefulness on behavioral intention. This could mean

    that participants' intention to use a computer-based listening

    comprehension test would hardly be affected by their perceptions

    on the usefulness of the system. This nding could have been

    resulted from two other reasons. One is that the WBT aimed to test

    listening comprehension. The students did not have sufcient

    awareness of foreign language learning, because they are expected

    to be low rank military personnel and not to have duties in inter-

    national platforms. Another reason might be that students were

    novice in using computer as a tool for an exam. Presenting a

    consistent result withTerzis, Moridis, and Economides (2012), the

    current study did not reveal any signicant inuence of perceived

    ease of use on perceived playfulness, which might be discussed

    through the characteristics of the contemporary users of such

    systems; because they were novice in using computer as an

    assessment tool although they took computer-related courses

    previously. The difculties experienced during the administration

    of the computer-based listening assessment might cause a decrease

    in the perceived ease of use and perceived playfulness.

    In line with the previous studies such as Cigdem and Topcu

    (2015), Terzis and Economides (2011); Terzis et al. (2012);

    Venkatesh and Davis (2000), social inuence was attributed to be

    a critical determinant of perceived usefulness. Similar ndings

    regarding the previous studies might be explained by the social

    sharing related to the exam format and item types before the exam

    sessions.In addition to those points, it was seen that the content of the

    items in the test seemed to affect signicantly the perceived use-

    fulness of the systemas in the study ofCigdemand Oncu (2015) and

    Terzis and Economides (2011), who suggested that users would

    tend to consider the system as useful when their perceptions about

    the content of the questions in a WBT system were positive. At this

    point, low scores on the content meant that students perceived the

    test items harder than they expected and more time-consuming

    than they imagined. However, preparing items that are easier to

    comprehend and handle could probably have a positive impact on

    the use of a computer-based listening comprehension test.

    8. Conclusion

    This study examined the constructs that inuence students'

    behavioral intentions to use WBT in a military vocational college

    and concluded that perceived playfulness and perceived ease of use

    exerted direct effects on behavioral intention to use WBT. Accord-

    ingly, when the students feel that WBT is playful enough and easy

    to use, their behavioral intention to use such a system seems

    stronger. Bearing this in mind, certain techniques adopted to

    improve the dimensions of perceived playfulness and perceived

    ease of use with other means would have a positive impact on the

    systems' being accepted. Besides, some game-based or real life-

    oriented themes might be embedded into the items so that they

    could facilitate the comprehension and thus the students could nd

    the procedures more playful and easy to use.

    Perceived usefulness had no direct impact on behavioral

    intention to use WBT which contradicted with the TAM literature.

    Goal expectancy was positively impacted by content of questions.

    Furthermore, computer self-efcacy and facilitating conditions had

    direct effect on perceived ease of use. Perceived usefulness was

    positively impacted by content of test items, perceived ease of use

    and social inuence. Finally, perceived usefulness and content of

    test items had direct impact on perceived playfulness.

    To sum up, WBT is more likely to be playful when it is useful and

    the content of WBT items tends to be easier to understand. Most

    practical implications for foreign language educators might be that

    the content of the audio items should be based on a problem or a

    case or a real life situation. This might increase the intention to use

    such an application as a result of an increase in the perceived ease

    of use and playfulness.

    9. Limitations

    A wide range of web-based testing systems exist acrossdifferent

    educational settings such as the ones that incorporate videos,

    graphics, animations and simulations. Yet in the current study, the

    students were tested on their listening comprehension and audios

    were incorporated into the assessment procedures. Listening

    comprehension is among the most challenging skills both in

    teaching and testing procedures; thus, it is possible that test-takers

    have difculties in all types of listening comprehension tests

    whether it is paper-based or computer-based. It is also acceptable

    that test-takers reect different interpretations of and attitudes

    towards various types of computer-based assessment, but their

    perceptions on a computer-based listening comprehension test is

    expected to be different from the ones in other subjects. Therefore,

    the ndings ought to be interpreted through the lenses of the

    subject of listening comprehension' and of the domain of military

    students' having no powerful targets related to learning English.

    The study on the whole limited to the research context, which is

    a two-year post-secondary military vocational college. Broadening

    the scope with other post-secondary institutions across various

    disciplines would add more value to similar studies. Gender issue

    wasanother limitations as the male military students outnumbered

    the females. A future study could consider eliminating the imbal-

    ance of gender by including more female students.
