Teacher–Child Interactions in Early Head Start Classrooms: Associations With Teacher Characteristics     

Sherri Castle  Amy C. Williamson  Emisha Young  Jessica Stubblefield  Deborah Laurin  Nicole Pearce 《Early education and development》2016,27(2):259-274

ABSTRACT

Research Findings: The current study examined characteristics of 71 Early Head Start lead teachers in relation to classroom interactions with infants and toddlers. Measured teacher characteristics included education, years of experience, beliefs about child rearing, depressive symptoms, and the temperamental characteristics of positivity and frustration. Teacher–child interactions were measured using the Classroom Assessment Scoring System, Toddler Version (La Paro, Hamre, & Pianta, 2012). Results indicated that field of degree was directly associated with the majority of dimensions of teacher–child interactions. Examination of teachers’ years of experience and intrapersonal characteristics revealed a number of significant interactions, indicating that teacher experience and appropriate beliefs may serve as protective factors in the presence of psychosocial risk factors. Practice or Policy: Overall, our findings suggest that both early childhood education degrees and years of experience are directly or indirectly associated with multiple dimensions of teacher–child interactions, confirming that these patterns established for preschool teachers hold for teachers of infants and toddlers. These results also suggest that years of experience and progressive beliefs about children may be especially important for teachers who are depressed or who have low levels of positivity and high levels of frustration. Implications for future research, as well as preservice and in-service professional development, are discussed.  相似文献   

“Science of the singular”: an explanatory single case study of whole school guidance counselling in Ireland     

Lucy Hearne  Paul King  Tom Geary  Neil Kenny 《International Journal for Educational and Vocational Guidance》2018,18(3):315-335

This article will discuss the findings of a single explanatory case study on the model of whole school guidance counselling in the Irish secondary school system, which was carried out during a turbulent period of policy and practice changes in the delivery of guidance counselling services to students from 2012 onwards. Although the case study is positioned within a single voluntary school, the findings may be typical of similar secondary schools settings in Ireland and abroad. Particular focus is given to explicating the key findings of the case study through the specific themes of: concepts of whole school guidance counselling, the Irish integrated model of guidance counselling, stakeholder roles and responsibilities, and the effect of resource re-allocations by policy makers funding guidance school services.  相似文献   

Can narrative cutscenes improve home learning from a math game? An experimental study with children     

Tomáš Sýkora  Tereza Stárková  Cyril Brom 《British journal of educational technology : journal of the Council for Educational Technology》2021,52(1):42-56

Little is known about the instructional effects of narrative framing elements in child learning games. In this study, second and third graders (M_age = 8.24) played one of two versions of a successful, commercial mathematical learning game at home for 2 weeks (N = 95; between-subject design). The versions differed in the presence/absence of a background story conveyed through comic cutscenes at the beginning and the end of the game. Results showed that children played the game intensively in both conditions: despite not being forced to do so. Plus, they also learned from the game. As expected, children assigned to the cutscenes condition interfaced with the cutscenes. However, no between-group difference was detected in pre-post learning gains, parent-reported engagement, self-reported enjoyment, time spent with the game and the number of solved in-game tasks (all |ds| < 0.29). Altogether, no advantage or disadvantage from the narrative comic cutscenes was revealed.  相似文献

Audio-video correspondence and its role in attention and memory     

Tom Grimes 《Educational technology research and development : ETR & D》1990,38(3):15-25

This study measured the effect of audio-video channel correspondence on attention and memory. Three versions of four TV news stories were the stimuli. The high-correspondence version employed a specific audio-video semantic match, the medium-correspondence version a less specific match, and the no-correspondence version no match. High channel correspondence promoted the most efficient division of attention and the best memory scores on visual and factual recognition measures. The medium-correspondence version yielded significantly worse visual memory and attention scores, but factual attention and memory scores equal to those for the high-correspondence version. The no-correspondence version yielded high visual recognition scores, but the worst visual attention scores, suggesting that attentional capacity boundaries were overwhelmed by the stimulus. The results across all conditions suggest that when attentional capacity is exceeded, memory of the overall story is degraded.  相似文献   

Media Education in the University: enhancing media literacy through first‐year undergraduate coursework     

Dugald Williamson 《Learning, Media and Technology》1999,24(3):203-215

This article provides a case study of a first‐year university subject designed to assist the development of media literacy. The context is one of ongoing debate about the purpose and role of media courses. In what ways do new communications technologies alter our understanding of media literacy? How can media subjects be most relevant to students following increasingly different educational pathways? The subject in question responded to such questions by seeking to promote independent capacities for research and writing in the changing media communications field. It used flexible learning techniques to encourage students to apply and reflect on writing formats drawn from professional fields such as journalism and screen production. In doing so, it aimed to encourage interest in the broader social conditions affecting media practices and the diverse settings in which these forms can operate. Through the case study, the article draws out some of the problems encountered in resource‐based learning and suggests some strategies for dealing with them in media education.  相似文献   

Social working memory: Memory for another rat's spatial choices can increase or decrease choice tendencies     

Brown MF  Knight-Green MB  Lorek EJ  Packard C  Shallcross WL  Wifall T  Price T  Schumann E 《Learning & behavior》2008,36(4):327-340

In two experiments using a radial-arm maze, pairs of rats made choices among eight maze locations, each containing a large quantity of one of two food types. The choices made by 1 rat affected the choices made by the other rat. Under most conditions, visits by 1 rat increased the tendency of the other rat to subsequently choose that maze location. However, the effect depended on the quality of the food available in a particular location. When it was possible for the rats to observe each other on the maze arms and a rat had experienced that a location contained the less preferred food type, a previous visit to that location by the foraging partner decreased the tendency to visit that location. These effects are attributed to working memory for the spatial choices of another rat, and they indicate that memory produced by a rat’s own visit to a maze location is integrated with memory for the behavior of another rat to determine spatial choice  相似文献
