Emotional experience, expression, and regulation of high-quality Japanese elementary school teachers
The present study investigates the emotional experience, expression, and regulation processes of high-quality Japanese elementary school teachers while they interact with children, in terms of teachers’ emotional competence. Qualitative analysis of interview data demonstrated that teachers had various emotional experiences including self-elicited negative emotions. The major expression patterns were identified as direct staging and the suppression of emotions. Teachers considered emotion expression in front of children as a skill, and their emotion regulation processes involved considering various purposes, appropriately using emotion expression, and ideal teacher images. The findings suggest that high-quality teachers effectively use emotional competence in teaching. 相似文献

In one study, parameters were estimated for constructed-response (CR) items in 8 tests from 4 operational testing programs using the l-parameter and 2- parameter partial credit (IPPC and 2PPC) models. Where multiple-choice (MC) items were present, these models were combined with the 1-parameter and 3-parameter logistic (IPL and 3PL) models, respectively. We found that item fit was better when the 2PPC model was used alone or with the 3PL model. Also, the slopes of the CR and MC items were found to differ substantially. In a second study, item parameter estimates produced using the IPL-IPPC and 3PL-2PPC model combinations were evaluated for fit to simulated data generated using true parameters known to fit one model combination or ttle other. The results suggested that the more flexible 3PL-2PPC model combination would produce better item fit than the IPL-1PPC combination. 相似文献

Reading and Mathematics tests of multiple-choice items for grades Kindergarten through 9 were vertically scaled using the three-parameter logistic model and two different scaling procedures: concurrent and separate by grade groups. Item parameters were estimated using Markov chain Monte Carlo methodology while fixing the grade 4 population abilities to have a standard normal distribution. For the separate grade-groups scaling, grade groupings were linked using the Stocking and Lord test characteristic curve procedure. Abilities were estimated using the maximum-likelihood method. In either content area, scatterplots of item difficulty, discrimination, and ability estimates from the two methods showed consistently strong linear relationships. However, as grade deviated from the base grade of four, the best-fit linear line through the pairs of item discriminations started to rotate away from the identity line. This indicated the discrimination estimates from the separate grade-groups procedure for extreme grades to be, on average, higher than those from the concurrent analysis. The study also observed some systematic change in score variability across grades. In general, the two vertical scaling approaches yielded similar results at more grades in Reading than in Mathematics. 相似文献

Complexation of π-conjugated ligands by metal or semimetal ions leads to the enhancement of the planarity and rigidity of π-conjugated systems. Boron, especially, has played a central role in the design of luminescent main-group complexes. However, these complexes still suffer the disadvantage of aggregation-caused quenching as well as typical organic fluorophores. It has recently been reported that some types of boron complexes exhibit the aggregation-induced emission (AIE) property. Moreover, AIE behavior from complexes and organometallic compounds composed of the other group 13 elements, such as aluminum and gallium, has emerged in this decade. These observations greatly encourage us to develop advanced functional materials based on the group 13 elements. Indeed, recent research has demonstrated that these classes of materials are potentially versatile scaffolds for constructing chromic luminophores, efficiently emissive π-conjugated polymers and so on. This review mainly describes AIE-active group 13 complexes with four-coordinate structures and their application as photo-functional materials. Proposed mechanisms of the origins of AIE behavior are briefly discussed. 相似文献

Prosody refers to features of speech such as intonation, volume and pace. In this paper, we examine teacher–student dialogue in an English lesson at a secondary school in England, using Conversation Analysis notation to mark features of prosody. We also make connections with Goffman's theoretical concept of footing. We show that, within an episode of teacher-led plenary discourse, prosody may be used to signal shifts in footing between different kinds of pedagogic activity. We identify: (i) teacher-led IRF (Initiation–Response–Feedback) discussion; (ii) the teacher's modelling of exploratory talk; (iii) a shift to instruction-giving. If teachers are able to model the enquiring tone of exploratory talk, they may in turn encourage more thoughtful contributions from students. 相似文献

Outdoor exercise often proceeds in rainy conditions. However, the cooling effects of rain on human physiological responses have not been systematically studied in hot conditions. The present study determined physiological and metabolic responses using a climatic chamber that can precisely simulate hot, rainy conditions. Eleven healthy men ran on a treadmill at an intensity of 70% VO2max for 30 min in the climatic chamber at an ambient temperature of 33°C in the presence (RAIN) or absence (CON) of 30 mm · h?1 of precipitation and a headwind equal to the running velocity of 3.15 ± 0.19 m · s?1. Oesophageal temperature, mean skin temperature, heart rate, rating of perceived exertion, blood parameters, volume of expired air and sweat loss were measured. Oesophageal and mean skin temperatures were significantly lower from 5 to 30 min, and heart rate was significantly lower from 20 to 30 min in RAIN than in CON (P < 0.05 for all). Plasma lactate and epinephrine concentrations (30 min) and sweat loss were significantly lower (P < 0.05) in RAIN compared with CON. Rain appears to influence physiological and metabolic responses to exercise in heat such that heat-induced strain might be reduced. 相似文献

Problem solving as a skill is emphasized within the revised Japanese Course of Study for schools. This experimental study,
conducted among Japanese high school students, evaluates an effort to develop student ability to identify reasons fordifferent points of view, not just personally favored views. First, the ability of all students was tested using a reading literacy
question from the 2000 PISA test, which measures the reading skills of evaluation and reflection. The experimental group then
participated in a developmental learning activity. After the activity, all students were retested using the same PISA question.
Nothing conclusive was found regarding the general effectiveness of the lesson activity, but two insights were gained. It
was found that student self-awareness of the importance of the learning task and interactive learning are important to consider. 相似文献
