This study explored the contribution of technology acceptance and technological selfefficacy to attitude toward technology-based self-directed learning in a sample of Chinese undergraduate students. The study also inquired into whether learning motivation mediated these associations. A total of 332 undergraduate students of college English course were enrolled to participate in questionnaires regarding their technology acceptance, technological self-efficacy, attitude toward technology-based self-directed learning, and learning motivation. Results indicated that students' technology acceptance and technological self-efficacy were related to their attitude toward technology-based selfdirected learning. The findings also indicated that learning motivation mediated the relations of technology acceptance, technological self-efficacy, and attitude toward technologybased self-directed learning. Specifically, students experiencing greater technology acceptance and technological self-efficacy showed higher attitude toward technologybased self-directed learning. This study highlighted the significance of learning motivation as a mediating mechanism illustrating relations between students' perception of technology environments and their attitude toward technology-based self-directed learning.

Teacher online feedback (TOF) through online course delivery has been identified as key to promoting and validating knowledge in online learning environments. We examined the relationships between TOF, learning motivation, and learning engagement, and the mediating role of learning engagement in the relationship between TOF and learning motivation, using structural equation modeling and bootstrap analysis. Participants comprised 312 university students of College English courses in China. The results indicated that TOF was positively related to both learning motivation and learning engagement. Further, the positive effect of TOF on learning motivation was partially mediated by learning engagement. Theoretical implications and practical implications for language teachers' implementation of TOF are discussed.

This study explored the contributions of teacher supports toward students’ self-directed language learning beyond the classroom and investigated whether technology acceptance and technological self-efficacy could be the mediators between teacher supports and students’ self-directed language learning in a sample of Chinese undergraduate students. A total of 197 freshmen students in one university in Eastern China participated in the questionnaires concerning teacher supports, technology acceptance, technological self-efficacy and self-directed language learning. The study highlighted the results: (1) perceived usefulness mediated the relationship between teacher affective supports and students’ self-directed language learning as well as the relationship between teacher capacity supports and students’ self-directed language learning; (2) technological self-efficacy mediated the relationship between teacher affective supports and students’ self-directed language learning as well as the relationship between teacher behavior supports and students’ self-directed language learning; and (3) perceived easy of use had no noticeable mediating functions, but exerted an indirect influence on students’ self-directed language learning. These findings extended previous researches by considering both the external factors (i.e., teacher supports) and the internal factors (i.e., technology acceptance and technological self-efficacy) of influencing students’ self-directed language learning, thereby contributing to enhancing our understanding of the joint drive of the inherent and extrinsic power mechanisms. This study indicated the significance of elevating teachers’ awareness of the substantial supports in enhancing students’ self-directed language learning beyond the classroom and would inform that the future research on teachers’ compliance in relation to technology use be converted from institutional mandates into teachers’ conscientious behaviors.

The construction of an effective technology-based environment to promote learning and enable online learning to truly empower learners has become an increasingly important issue of concern. To some extent, an in-depth analysis of the key influencing factors and their functioning mechanism of online learning supporting learners’ empowerment may pave a new way for the understanding of this issue. In view of this, this study, grounded on the reciprocal determinism theory, explored the influencing paths among environment elements, online behaviors, person factors, and learners’ empowerment by using structural equation modeling (SEM) approach, and examined the structure effect relationships among these dimensions. A total of 396 Chinese university students reported on their perceptions of environment elements, online behaviors, person factors, and learners’ empowerment through the questionnaire survey. The results showed that there was a strong correlation between the three dimensions of the reciprocal determinism theory, and the three dimensions all exerted a positive effect on learners’ empowerment. Among them, the item parameter estimates revealed that online environment, online interaction, and online cooperation were significant in explaining the influence of environment elements and online behaviors on learners’ empowerment. Based on the empirical results, this study provided some implications and suggestions for the rationality of the structure devising of online learning environment, the effectiveness of online teacher-student interaction, and the development of students’ learning autonomy in technology-based learning. Thus, this study helped understand the specific contribution of external and internal factors to learners’ empowerment of using technology for online learning and would inform the construction of the optimized online learning environments and teacher-student relationships to enhance students’ sense of online presence and learning initiative.

This study explored how 26 Chinese EFL teachers perceived community-based, technology-supported professional development practices. The methods of data collection in this study blend quantitative and qualitative techniques: 1) questionnaire survey of teachers' satisfaction about community-based technology-supported professional development practices; 2) online teacher discussion postings; 3) teacher self-reflection journals; and 4) semi-structured interviews. Data analysis revealed a generally positive attitude and empowering feelings in these Chinese EFL teachers who viewed technology-facilitated practices as affording constructive functions for their professional development. Results also revealed a range of factors that apparently mediated/limited EFL teachers' participation in the professional development activities. This study thus contributes to the understanding of the reality in relation to actual utilization of technological resources in second-language teacher development in the context of a developing country such as China.
