This article focuses on the scholarship of Black mathematics education researchers whose work focuses on Black students in P–20 mathematics spaces. We conducted a metasynthesis literature review of empirical studies by Black mathematics education researchers. The authors utilized critical theories of race and racism to aid in the synthesis of the literature. The Black researchers we reviewed challenged the perspective that failure and limited persistence in Black students who are learning and participating in mathematics is normative. As a critical defense, these scholars offer research that problematizes test score data, race and racism, opportunities to learn mathematics, identity considerations, and other constructs that produce unequal effects in mathematics learning. We found that Black mathematics education researchers strategically disrupt the deficit narrative about Black students. Black scholars select theoretical frameworks that allow them to focus on race and how racism operates in mathematics education. We present this research to incite dialogue among all mathematics educators about improving the mathematical context for Black students.  相似文献

Black students face repeated racial microaggressions that may challenge their mental health and academic performance in engineering doctoral programs. Researchers attribute this to stereotypes and institutional climates that juxtapose their STEM and racial identities as incongruent. In this article, we analyzed the perceptions of environmental, behavioral, and verbal racial microaggressions of 33 Black doctoral students and postdocs, with a focus on their interactions with non-Black peers. Data were collected through semi-structured interviews with Black doctoral students from 11 Predominantly White Institutions in the United States. To analyze the experiences of our participants, we utilized two theoretical frameworks: Racial microaggressions and identity nonverification. Across the interviews, participants described various forms of racial microaggressions that greatly challenged their sense of belonging and identities as engineers. This research affirms the need to develop initiatives at the departmental and institutional levels to encourage more inclusive spaces for diverse students in STEM doctoral programs and to combat the types of exclusionary practices found in this study.  相似文献

This research aims to study the ontologization process of the Romani minority in Abruzzo region (Italy), characterized by the longstanding presence of a group of sedentary Romani, and to test the cross-categorization approach using a specific dependent measure such as the ontologization of the Italian Romani target. A questionnaire was administered to 475 Italian participants, in which the respondents were asked to attribute 6 human positive, 6 human negative, 6 animal positive and 6 animal negative associates to three targets: Italians (ingroup), Italian Romani (ingroup–outgroup) and Romani (outgroup). Participants showed evidence that they used human/animal associates differently for the ingroup and for the outgroup members. Romani groups were ascribed more animal than human characteristics, while Italians were described as more human than the Romani and Italian Romani group, showing the ontologization process of the Romani minority and the superhumanization of the Italian ingroup. Moreover, the cross-categorized Italian Romani target was the most discriminated against in that it was attributed more animal negative associates than the Romani and Italian ones. Since modern racism could take the form of the denial of the humanness and the attribution of animality to outgroup members, our data emphasize the importance of taking account of the persistence of negative attitudes so deep-rooted as those felt towards the Romani.  相似文献

Giovanni Fattori (Livorno 1825–Firenze 1908) is the most representative artist of the Macchiaioli's current, an early group of Italian plein-air artists, whose work anticipates, in the xixth century, that of their younger contemporaries, the French Impressionists. The study, performed by a multidisciplinary team made up of scientists and conservators, presents the results of the scientific characterization carried out on a group of 10 paintings made by Fattori between 1854 and 1893 and shows the way he used complex mixtures of a large variety of traditional and synthetic pigments, ranging from lead white, found pure and also extended with calcium carbonate, natural barite and gypsum to zinc white, from red ochre to cinnabar and vermilion, from yellow ochre and Naples yellow to chrome yellow, cadmium yellow and zinc yellow, combined with many other ones reported in details. This paper highlights the evolution of his painting technique during a time of great technological and social innovations and puts forward some hypothesis on his awareness about manufactured pigments, i.e. tube paints recently introduced into the artists’ circles. The wide range of pigments and their different quality among the same synthetic products suggest that the artist used all the available materials, and that picking out the pigments he retained the early xixth century artists techniques, such as the use of mineral earths and Prussian blue, similarly to his contemporary Italian artists Federico Zandomeneghi and Telemaco Signorini, but he also experimented new and peculiar pigment mixtures in the making of “colored darks” and an innovative use of the grounds in the final composition, that are also distinctive features of the French Impressionists. This work is aimed at contributing to overcome the lack of a comprehensive overview on the widespread historical and scientific data collected up to now on the Italian paintings in the xixth century, which has been severely underestimated with respect to previous art movements.  相似文献

OBJECTIVES: Although women with histories of child sexual abuse (CSA) perceive themselves as less competent mothers and report greater parenting difficulties than nonabused women, few investigators have actually observed the parenting behaviors of CSA survivors. The primary aim of this study was to examine whether incest history was related to maternal perceptions of parenting efficacy and interactional patterns with their children. The secondary aim of this study was to explore the constructs of internal working models of relationships and maternal psychological adjustment as potential mediators of the relation between incest history and parenting. METHODS: A community sample of 17 incest survivors, 18 nonabused women and their 3-6 year-old children participated. Mothers completed self-report measures of parenting efficacy, parental bonding (i.e., internal working models of relationships), and psychological adjustment. In addition, mothers interacted with their children in a problem-solving task. RESULTS: Although incest survivors reported less parenting self-efficacy than did nonabused mothers, their interactional styles with their children were positive overall and comparable to those of nonabused mothers. Specifically, survivors displayed moderate to high levels of support, assistance, and confidence, and their children showed high levels of affection towards their mothers. Incest survivors reported less bonding with their own mothers in childhood and poorer current psychological adjustment. CONCLUSIONS: Findings suggest that incest survivors' perceptions of their parenting abilities may be more negative than their actual parenting behaviors.  相似文献

Using longitudinal data from the UCLA Cooperative Institutional Research Program (CIRP) and Your First College Year (YFCY) surveys, this study examines predictors of the likelihood that science-oriented students would participate in a health science undergraduate research program during the first year of college. The key predictors of participation in health science research programs are students’ reliance on peer networks and whether campuses provide structured opportunities for first-year students even though only 12% of freshmen in the sample engaged in this activity. These experiences are particularly important for Black students. The findings inform efforts to orient students at an early stage, particularly under-represented minorities, toward biomedical and behavioral science research careers.

We present an empirical investigation of a classroom training fostering vocational students’ consideration of source information when deciding about science-based controversies. The training was specifically aimed at raising students’ awareness of the division of cognitive labor and the resulting need to take a source’s competence into account when deciding whom to trust. Data were collected from a training group and a waiting list control group in a pretest–posttest design. The results show that students benefitted from the training in terms of their inclination to agree with pertinent expert sources rather than low-pertinent experts and to refer to the source of information to justify their judgment. Source memory was not affected by the training.  相似文献
