Preservice Elementary Teachers’ Voices Describe How Their Teacher Motivated Them to do Mathematics     

Shelly Sheats Harkness  Beatriz D&#;ambrosio  Anastasia S. Morrone 《Educational Studies in Mathematics》2007,65(2):235-254

In this study, data in the form of (preservice teacher) student voices taken from mathematical autobiographies, written at the beginning of the semester, and end-of-semester reflections, were analyzed in order to examine why preservice elementary school teachers were highly motivated in a social constructivist mathematics course in which the teacher emphasized mastery goals. The findings suggest that students entered the course with a wide variety of feelings about mathematics and their own mathematical ability. At the end of the semester, students wrote about aspects of the course that “led to their growth as a mathematical thinker and as a mathematics teacher…” Student responses were coded within themes that emerged from the data: Struggle; Construction of meaning [mathematical language; mathematical understanding]; Grouping [working in groups]; Change [self-efficacy; math self-concept]; and the Teacher’s Role. These themes are described using student voices and within a motivation goal theory framework. The role of struggle, in relation to motivation, is discussed.  相似文献   

Maturation of cognitive processes from late childhood to adulthood   总被引：2，自引：0，他引：2  

Luna B  Garver KE  Urban TA  Lazar NA  Sweeney JA 《Child development》2004,75(5):1357-1372

To characterize cognitive maturation through adolescence, processing speed, voluntary response suppression, and spatial working memory were measured in 8- to 30-year-old (N = 245) healthy participants using oculomotor tasks. Development progressed with a steep initial improvement in performance followed by stabilization in adolescence. Adult-level mature performance began at approximately 15, 14, and 19 years of age for processing speed, response inhibition, and working memory, respectively. Although processes developed independently, processing speed influenced the development of working memory whereas the development of response suppression and working memory were interdependent. These results indicate that processing speed, voluntary response suppression, and working memory mature through late childhood and into adolescence. How brain maturation specific to adolescence may support cognitive maturation is discussed.  相似文献

Developmental effects of incentives on response inhibition     

Geier CF  Luna B 《Child development》2012,83(4):1262-1274

Inhibitory control and incentive processes underlie decision making, yet few studies have explicitly examined their interaction across development. Here, the effects of potential rewards and losses on inhibitory control in 64 adolescents (13- to 17-year-olds) and 42 young adults (18- to 29-year-olds) were examined using an incentivized antisaccade task. Notably, measures were implemented to minimize age-related differences in reward valuation and potentially confounding motivation effects. Incentives affected antisaccade metrics differently across the age groups. Younger adolescents generated more errors than adults on reward trials, but all groups performed well on loss trials. Adolescent saccade latencies also differed from adults across the range of reward trials. Overall, results suggest persistent immaturities in the integration of reward and inhibitory control processes across adolescence.  相似文献   

The intellectual labour market in developed and developing countries: Women's representation in scientific research     

Beatriz Ruivo 《International Journal of Science Education》2013,35(3):385-391

Women's representation in scientific research in countries with differing levels of development is analysed. The under‐representation of women in this area is worse in developed countries than in the group of semi‐industrialized and newly industrialized countries. In countries which were late to industrialize, the development of science took place at a stage when women's economic and social participation was more acceptable. Moreover, in developing countries the links between research and the productive system are weak. Both facts are connected with greater discrimination against women in scientific research in developed countries. Within the framework of long‐term economic cycles and technological change, some assumptions can be made about the future. This approach can be used to set up a theoretical framework for women's strategies.  相似文献

The Spanish Version of the Empathy Questionnaire (EmQue): Evidence for Longitudinal Measurement Invariance and Relationship With Emotional Regulation     

Beatriz Lucas-Molina  Renata Sarmento  Laura Quintanilla  Marta Giménez-Dasí 《Early education and development》2018,29(4):467-476

Research Findings: Empathy, or the ability to understand what others are thinking or feeling, can be observed in early developmental stages. The purpose of this study was to validate the Spanish version of the Empathy Questionnaire (EmQue) and examine its longitudinal measurement invariance (LMI) at 2 time points. Parents of 103 children completed the EmQue when their children were 3 (M = 41.76) and 4 (M = 51.65) years old. Confirmatory factor analyses revealed that Grazzani, Ornaghi, Pepe, Brazzelli and Rieffe’s (2016) 3-factor model of emotional contagion (EC), attention to others’ feelings, and prosocial actions (PA) presented the best fit indices at both time points (Time 1: CFI = .931, TLI = .914, and RMSEA = .070; Time 2: CFI = .941, TLI = .935, and RMSEA = .064). Moreover, preliminary evidence was obtained for the LMI of this model. PA scores increased over time. Score reliability ranged from .60 (EC) to .83 (PA). Positive correlations were found between PA and emotional regulation at each time point and across time.Practice or Policy: The great relevance of empathy and prosocial behavior in academic achievement and psychological adjustment justifies the development of reliable instruments to evaluate these constructs from early ages.  相似文献   

Emergence of Global Shape Processing Continues Through Adolescence     

K. Suzanne Scherf  Marlene Behrmann  Ruth Kimchi  and Beatriz Luna 《Child development》2009,80(1):162-177

The developmental trajectory of perceptual organization in humans is unclear. This study investigated perceptual grouping abilities across a wide age range (8–30 years) using a classic compound letter global/local (GL) task and a more fine-grained microgenetic prime paradigm (MPP) with both few- and many-element hierarchical displays. In the GL task, contrary to adults, both children and adolescents exhibited a classic local bias. In the MPP, all 3 age groups evinced a bias to individuate the few-element displays; however, the ability to encode the global shape of the many-element displays at the short prime durations increased with age. These results indicate that the full process of garnering shape information from perceptual grouping, which is essential for the ability to do fast and efficient object recognition and identification, develops late into adolescence.  相似文献   

The (in)visibility of gender knowledge in the Physical Activity and Sport Science degree in Spain     

Pedrona Serra  Maria Prat  María Teresa Vizcarra  Beatriz Garay  Anne Flintoff 《Sport, Education and Society》2018,23(4):324-338

This paper draws on research that aimed to explore the construction of gender relations in sport and physical education (PE) through a national study of Spanish university degree curricula. Spain is a useful case study through which to explore gender knowledge within sport and PE degrees, because, unlike many other countries, it has a common, national curriculum framework for its Physical Activity and Sport Science (PASS) degrees. In addition, it has recently passed a new law concerning the introduction of gender knowledge in higher education (HE). Drawing on Bernstein’s (1990) framework of the pedagogic device, this paper examines how this HE gender policy becomes recontextualised as universities and lecturers interpret and translate this into the pedagogical texts that make up the PASS curricula. Purposive sampling was used to select 16 of the 37 universities offering PASS degrees in 2012/2013. The research analysed 16 PASS documents at the degree level and 763 individual subject handbooks. Using discourse analysis, the results showed where and how gender knowledge was incorporated and the extent to which the topic was presented coherently throughout the documents. The analysis revealed five categories of the (in)visibility of gender knowledge within the universities’ instructional discourse. Gender knowledge is largely ignored in PASS curricular documentation, appearing, at best, in highly superficial ways. Despite a national policy requirement on universities to incorporate gender knowledge, this study shows how recontextualisation processes within specific universities’ pedagogic devices operate to marginalise such perspectives within PASS curricula. The research also revealed the significance of individual agents committed to gender equity being situated, and having influence, throughout the pedagogic device. The paper concludes that without a much wider, critical engagement in knowledge about gender equity, PASS degrees will continue to reproduce rather than disrupt the gender relations that have traditionally characterised the field.  相似文献
