In teacher identity research, limited attention has been paid to how pre-service teachers constructed their identities by negotiating with different emotions in their practice. To fill this gap, the present study, drawing upon the approach of narrative inquiry, explores how a student-teacher – Ming – negotiated and navigated conflicting emotions in the process of becoming a teacher. The findings show that while Ming experienced some negative feelings in his work, which challenged his self-belief as a teacher, the positive emotions derived from his students’ progress and recognition contributed to his teacher identity. However, due to the constraints imposed by his mentor and the school context, his negative emotions gradually escalated, posing severe impediments to his teacher identity. The emotional flux and identity change of the student-teacher can be attributed to his professional learning in the structural and cultural working conditions with hidden ‘emotional rules’ embedded in the practicum school. This paper argues for the inclusion of teacher emotions as an indispensable part of pre-service teacher education.  相似文献

This interdisciplinary research examines how Informal Digital Learning of English (IDLE) and the L2 Motivational Self System (consisting of the ideal L2 self and the ought-to L2 self) are linked with Foreign Language Enjoyment (FLE). Together, these are flourishing research areas in computer-assisted language learning, second language acquisition and positive psychology. Using a purposive sampling technique, three cohorts of English-as-a-foreign-language learners (N = 661) are surveyed in South Korea: middle school (n = 173), high school (n = 374) and university students (n = 114). Results of hierarchical regression analyses show that IDLE and the ideal L2 self are significantly predictive of all groups’ FLE, while the ought-to L2 self predicts only middle school students’ FLE. These results suggest that students’ engagement in extramural digital activities and their motivational mindset (shaped through different socio-educational contexts) may have influenced their emotions in learning their target language. Informed by these results, teachers can help increase students’ L2 learning enjoyment by supporting their language learning in out-of-class digital settings as well as promoting their ideal L2 self-images. Concurrently, teachers and parents can enhance younger learners’ enjoyment of learning L2—especially in test-oriented Asian contexts—by setting higher L2 learning expectations.  相似文献

The current popularity of flipped learning may be attributed to its reported successes in bringing about enhanced learner engagement and positive learning outcomes. This study aims to improve our understanding of flipped learning (FL) outcomes by examining factors of learner engagement, academic capability, and epistemological beliefs. Data were collected and statistically analyzed from 231 undergraduate students enrolled in a general biology or general chemistry course at a Korean university implemented with the FL model. The results indicated that learners’ epistemological beliefs influenced neither pre-class nor in-class engagement, but that academic capability did affect both pre-class and in-class engagement. Only content/learning-related outcomes, not generic competencies or satisfaction, were affected by both academic capability and epistemological beliefs. Both pre-class and in-class engagement levels affected most types of FL outcomes except generic competencies, which were only affected by the extent of in-class engagement. Learners’ affective engagement was not influenced by epistemological beliefs, but directly and indirectly affected FL outcomes via behavioral and cognitive engagement. Theoretical and practical implications are discussed along with recommendations.  相似文献

张爱玲的《对照记》对照的是形象(照片)与个人身世的真实,因此她用文字来解释心得。《对照记》本身有很强的“后设性”,对《对照记》的解读,则是“后设”的“后设”。从《对照记》中所列的相当可观的张爱玲祖父祖母一代人的照片中,可以解读出她的怀古幽思,她所怀念的就是她祖父母这一代的人物和生活方式,这自觉或不自觉地展露了她的历史怀旧意识。《对照记》中没有张爱玲与父亲或母亲的合影,也没有她父母亲的合影,这些照片的缺失使《对照记》创设了一股幼时的失落感或被遗弃的情境,呈现出“褪了色”的苍凉。张爱玲自己的照片在全书中有30多幅,她的姿态在“镜花水月”式的美学意境中制造了一种神秘感。张爱玲“传奇”不仅是她的文字,也是她的形象造成的。  相似文献

Using a secondary device while viewing a primary device (i.e. TV), or media multitasking, is now common. Numerous researchers and practitioners have attempted to introduce secondary devices into education as a new learning environment providing additional information to the user. However, the learning-related effects of using a second screen remain controversial. This study examined the effects of second-screen-application use on attention, learning performance, and user experience per content relevance for three primary contents (PC; i.e. videos) requiring different amounts of cognitive load: low, medium, and high. Second-screen use reduced learning performance and user satisfaction when the PC required high cognitive load. However, participants exhibited increased learning performance, concentration, and satisfaction with the PC requiring medium-cognitive-load when highly relevant information was presented on the secondary screen simultaneously. Based on these findings, guidelines were suggested for designing a second-screen application without degrading users’ learning and experience.  相似文献

Dorfman et al. (1982) compared the professional activities of retired professors from liberal arts colleges, a comprehensive university, and a major research university. This companion piece based on the same survey compares the professors' reactions to retirement. Results show that a majority of faculty from all types of institutions plan for retirement, are positive about retirement, and give suggestions for institutional retirement policy. The retired professors recommend the following: (1) help in planning, (2) more information about retirement, (3) support for continued work, (4) gradual retirement. Major differences among institutions are the following: (1) comprehensive university faculty plan for retirement more than do faculty from the other institutions, (2) faculty from both universities begin financial planning at a younger age than do faculty from the liberal arts colleges, (3) research university faculty miss work and like having time to spend on professional activities more than do faculty from the other institutions.  相似文献

Scientific argumentation is one of the core practices for teachers to implement in science classrooms. We developed a computer-based formative assessment to support students’ construction and revision of scientific arguments. The assessment is built upon automated scoring of students’ arguments and provides feedback to students and teachers. Preliminary validity evidence was collected in this study to support the use of automated scoring in this formative assessment. The results showed satisfactory psychometric properties related to this formative assessment. The automated scores showed satisfactory agreement with human scores, but small discrepancies still existed. Automated scores and feedback encouraged students to revise their answers. Students’ scientific argumentation skills improved during the revision process. These findings provided preliminary evident to support the use of automated scoring in the formative assessment to diagnose and enhance students’ argumentation skills in the context of climate change in secondary school science classrooms.  相似文献

This paper explores the relationship among ICT infrastructure (i.e., computing devices and Internet), one-to-one computing program and student ICT activities in school. It also looks into the differences of how ICT is being used in the teaching of English, mathematics and science at the elementary school level in relation to the availability of computing devices, Internet connection and one-to-one program. A total of 360 Grade 5 students from three schools (120 students from each school) in the western part of Singapore participated in a questionnaire adapted from the Program for International Student Assessment (PISA) ICT Familiarity Component for Student Questionnaire regarding students’ ICT use. One of the participating schools has implemented a school-based one-to-one computing program for all its students for the past nine years, with the school providing the necessary computing devices for all its Grade 1 to 3 students and a student computer ownership program to encourage all its Grade 4 students to procure their own computing devices to be used till completion of elementary education at Grade 6. The regression analyses suggest that how ICT is being used plays a more significant role in predicting the frequency of ICT use for the various subject areas than ICT infrastructure and one-to-one computing program. Further analysis also reveals that one-to-one computing program and availability of computing devices have a significant interaction effect on the frequency of ICT usage for English but not for mathematics and science—the presence of computing devices seem to have an impact for the usage of ICT for English but not the other two subject areas. The findings concur with earlier studies that there are differences in frequency and how ICT is being used in the teaching of English, mathematics and science.  相似文献
