The purpose of this article is to describe findings from a study of teachers’ social interaction during discussions about students’ thinking. The goal of the discussions was for the teachers to interpret their students’ thinking as revealed from work on non-routine, thought-revealing mathematical tasks, known as model-eliciting activities. The research reported in this article focuses on instances during the discussions when the teachers engaged in what the researcher termed ‘mini-inquiries’, occasions during which the teachers inquired into why their students thought about the associated model-eliciting activities as they did or when the teachers inquired into the underlying mathematical complexities associated with the model-eliciting activities. During these mini-inquiries, the teachers typically engaged in one of four types of interaction patterns that enabled them to meet some of the challenges of attending to students’ thinking that are described in United States reform documents. 相似文献
Zebra finch song behavior is sexually dimorphic: males sing and females do not. The neural system underlying this behavior is sexually dimorphic, and this sex difference is easy to quantify. During development, the zebra finch song system can be altered by steroid hormones, specifically estradiol, which actually masculinizes it. Because of the ease of quantification and experimental manipulation, the zebra finch song system has great potential for use in undergraduate labs. Unfortunately, the underlying costs prohibit use of this system in undergraduate labs. Further, the time required to perform a developmental study renders such undertakings unrealistic within a single academic term. We have overcome these barriers by creating digital tools, including an image library of song nuclei from zebra finch brains. Students using this library replicate and extend a published experiment examining the dose of estradiol required to masculinize the female zebra finch brain. We have used this library for several terms, and students not only obtain significant experimental results but also make gains in understanding content, experimental controls, and inferential statistics (analysis of variance and post hoc tests). We have provided free access to these digital tools at the following website: http://mdcune.psych.ucla.edu/modules/birdsong. 相似文献
ABSTRACT Research on teacher motivation is increasing substantially. Several studies have demonstrated the relationship between the motivation and teaching behaviour of teachers. The objective of this study was to investigate the relationship between the perceived motivation of teachers and their actual teaching behaviour in the context of secondary education. A survey on teacher motivation yielded responses from 315 teachers from 28 schools across 13 provinces in Indonesia. These teachers were observed in their classrooms by trained observers using a validated observation scheme. Results of a multilevel analysis indicate that: (1) perceived controlled motivation does not predict actual teaching behaviour; (2) perceived autonomous motivation is a positive predictor of at least some domains of actual teaching behaviour. Higher levels of perceived autonomous motivation are associated with higher scores on classroom management and clarity of instruction. There is also a slight tendency (p < .10) for autonomous motivation to explain differences in other domains of teaching behaviour, with the exception of activating teaching. This study highlights the importance of autonomous motivation in relation to teaching quality. 相似文献
Research consistently shows that teaching behaviour is a highly-important indicator of learning environments. Based on a teacher effectiveness model with six observable teaching behaviour domains (safe learning climate, efficient classroom management, clarity of instruction, activating teaching, teaching–learning strategies, and differentiation), the present paper examines the psychometric quality of the My Teacher questionnaire for capturing student perceptions of teaching behaviour in the Spanish secondary-education context. Additionally, this study validated the model of teaching behaviour and student engagement and its relevance in Spain. 7114 students of 410 teachers attending 56 public and private Spanish schools constituted the sample. The six teaching behavioural dimensions model were confirmed in the Spanish context. Regarding student academic engagement, the presence of two domains (behavioural and emotional engagement) were confirmed. Furthermore, results of a multiple-group structural equation modeling path analysis, examining the relationship between teaching behaviour and student engagement across different teaching experiences, revealed differential effects of teaching behaviour influences on students’ engagement. The percentage of explained variance was larger for emotional engagement than for behavioural engagement. Furthermore, teachers’ teaching experience explained differences in the relationship between perceived teaching behaviour and engagement. Two domains (learning climate and activating teaching) appeared to be the two most-important teaching domains for students’ behavioural engagement while, for emotional engagement, the most important domains for student engagement were learning climate and teaching learning strategies.
A nap soon after encoding leads to better learning in infancy. However, whether napping plays the same role in preschoolers' learning is unclear. In Experiment 1 (N = 39), 3‐year‐old habitual and nonhabitual nappers learned novel verbs before a nap or a period of wakefulness and received a generalization test examining word extension to novel actors after 24 hr. Only habitual and nonhabitual nappers who napped after learning generalized 24 hr later. In Experiment 2 (N = 40), children learned the same verbs but were tested within 2–3 min of training. Here, habitual and nonhabitual nappers retained the mappings but did not generalize. The results suggest that naps consolidate weak learning that habitual and nonhabitual nappers would otherwise forget over periods of wakefulness. 相似文献
In the field of developmental social psychology there is a consensus concerning the social nature of intelligence. In spite of the important empirical investigations in this field over the last fifteen years, the influence of the quality of a relationship on joint problem-solving and learning is still poorly understood. This explorary study investigated the influence of socio-affective context on the interactive modalities surrounding social problem-solving discussions conducted with 32 dyads of 8-year-old Swiss francophone children. Sociometric interviews with children and teachers were carried out to identify the following naturally-ocurring socio-affective contexts: reciprocal friendship (RF), asymmetrical friendship (AF) and reciprocal absence of friendship (“reciprocal non-friendship” RNF; excluding enemies). Comparisons of verbal exchanges and dyadic performance across the three groups suggests that reciprocal friendship facilitates collaboration and the organization of collective work. Two rival hypotheses opposing socio-affective proximity (reciprocal friendship) and socio-affective distance (asymmetrical friendship and reciprocal absence of friendship) are discussed with respect to the influence of social interactions on social problem-solving. 相似文献
Past research has identified “paradoxes” in infant health and child welfare services involvement, whereby children of Latinos and immigrants often demonstrate better health and decreased risk for child protective services involvement when compared to whites of similar socioeconomic position. This population-based study examined whether a paradox exists among immigrant and U.S.-born Latino caregivers in the prevalence and magnitude of risks to child well-being when compared to whites of similar socioeconomic position. Data were drawn from a random, general population telephone survey of parenting practices in 50 California cities (n = 2,259), which was administered in English and Spanish. The sample included 1,625 U.S.-born whites (72.0%), 351 U.S.-born Latinos (15.5%) and 283 foreign-born Latino respondents (12.5%). After adjusting for covariates in logistic regression models stratified by household income, immigrant caregivers in lower income households reported odds of insufficient food for the child that were 12 times as large as those for whites (OR 11.97, 95% CI 2.87, 49.86); odds of reported inability to take the child to the doctor and leaving a child in a place of questionable safety were nearly eight times as large (OR 7.92, 95% CI 2.38, 26.36 and OR 7.93, 95% CI 1.73, 36.46 respectively). These relationships were attenuated or insignificant for immigrant caregivers in households with greater resources. Therefore, a paradoxical relationship between socioeconomic position and risks to child well-being was not identified. Further research is needed to better understand the complex relationships between such risks, child health, and child protective services involvement. 相似文献
The purpose of this study was to investigate if children perceived certain sports to be masculine, feminine, or neutral. Students attending a University Laboratory school (grades K-12) were asked to fill out a survey about sports during a class period, Children in grades K-6 were given a sport (such as baseball) and asked if a boy named David would play it, if a girl named Jane would play it, or if both David and Jane would play the sport. Students in grades 7-12 were asked to name their favorite athlete or team and sport and indicate what sports they felt was best for a girl and a boy. Then they were given a list of sports and asked to indicate, using a 5-point Likert-type scale, whether they believed the sport was masculine, neutral, or feminine. Results from loglinear analyses indicated that students sex-typed certain sports, such as aerobics and football. Additionally, although some responses from students in grades 7-12 indicated that individuals should be able to play any sport they wanted, there were many gendered rsponses in terms of what sport(s) girls and boys should participate in. The results are discussed with reference to Metheny's categories of permissible sports for girls and in the framework of the gender typing of sport. 相似文献
