The Role of Action Research in Fostering Culturally-Responsive Practices in a Preschool Classroom     

Mariana Souto-Manning  Christina Hanson Mitchell 《Early Childhood Education Journal》2010,37(4):269-277

Early childhood teachers and educational programs are expected to be the primary resources as children experience different and sometimes conflicting cultural contexts. Early educators can play a paramount role as young children move through fluid identities and start recognizing and navigating within and across spaces of cultural differences—e.g., between home cultures and the socially-dominant school culture. In this sense, we draw attention to a multi-year action research study, paying particular attention to the process whereby an early childhood teacher investigated, problematized, and challenged the nature of curriculum and practices in a diverse preschool classroom. We focus on the role of action research in fostering culturally-relevant teaching. As we do so, we analyze an early childhood teacher’s shifting perceptions of what it means to engage in culturally-relevant teaching, respecting and honoring cultural diversities.  相似文献   

Using the onto-semiotic approach to identify and analyze mathematical meaning when transiting between different coordinate systems in a multivariate context     

Mariana Montiel  Miguel R. Wilhelmi  Draga Vidakovic  Iwan Elstak 《Educational Studies in Mathematics》2009,72(2):139-160

The main objective of this paper is to apply the onto-semiotic approach to analyze the mathematical concept of different coordinate systems, as well as some situations and university students’ actions related to these coordinate systems. The identification of objects that emerge from the mathematical activity and a first intent to describe an epistemic network that relates to this activity were carried out. Multivariate calculus students’ responses to questions involving single and multivariate functions in polar, cylindrical, and spherical coordinates were used to classify semiotic functions that relate the different mathematical objects.  相似文献   

Detection of Catabacter hongkongensis in polluted European water samples     

Francesc Codony  Bárbara Adrados  Leonardo Martín Pérez  Mariana Fittipaldi  Jordi Morató 《Journal of Zhejiang University. Science. B》2009,10(12):867-869

The Catabacteriaceae is a new bacterial family with a unique member: Catabacter hongkongensis is a strictly anaerobic, non-sporulating, Gram-positive coccobacillus that is phylogenetically related to some clostridial clusters. Little is known of its epidemiology and environmental distribution, but the inclusion of its 16S rRNA gene sequence in GenBank has allowed it to be detected qualitatively. As a first approach for prospective surveys, a real-time polymerase chain reaction (PCR) procedure to identify C. hongkongensis has been developed. The presence of Catabacteriaceae in 29 water bodies subjected to possible human or animal impact has been investigated. Four of them were positive. The results confirm that highly polluted water can contain C. hongkongensis.  相似文献   

A brief history of family life education in Romania     

Mariana Momanu  Nicoleta Laura Popa 《Paedagogica Historica: International Journal of the History of Education》2018,54(3):266-286

Starting from the state of conceptual diversity, semantic ambiguity, and poor connection of family life education practices to current policies and theoretical models in Romania, our study aims at understanding the underlying meanings of these issues by recourse to the history of approaches in the field. To this purpose, we carried out a qualitative historical research, based on the thematic analysis of a set of educational works produced between the sixteenth century, when the first Romanian texts were written, and the present time. Primary historical sources are supplemented with reliable secondary sources, while the criteria used for the selection of texts were their relevance to family life education (FLE), and the notoriety of the works in the corresponding historical periods. As in western countries, the concept of FLE was coined in Romania at the beginning of the twentieth century, when the family education discourse was outlined, but the roots of the field can be traced even in the first printed texts. Although marked by strong moral and religious emphases during pre-modernity, FLE has entered the slow process of secularisation and evolved from the perspective of political, social, and moral reconstruction goals of modern Romania. However, FLE’s goals and contents were redefined during Communism, and the discrepancies between discourses, practices, and realities compromised the functionality of the pedagogical model promoted at the time. A unitary definition of FLE in relation to Romanian contemporary families’ needs requires reconciliation with historical, cultural, and educational premises, as well as a careful contextualisation of western models and practices.  相似文献   

The AGTR2 rs11091046 (A>C) polymorphism and power athletic status in top-level Brazilian athletes     

João Paulo Limongi França Guilherme  Mariana Sussi Silva  Rômulo Bertuzzi  Antonio Herbert Lancha Junior 《Journal of sports sciences》2018,36(20):2327-2332

The main purpose of this study was to investigate if the rs11091046 (A>C) polymorphism in AGTR2 gene is associated with athletic status in top-level athletes from Brazil. Since the AGTR2 gene is located on the X chromosome, the case-control association study was done separately for women and men. The female cohort was composed of 205 athletes and 241 non-athletes, and the male cohort was composed of 419 athletes and 490 non-athletes. We did not identify an association between the C-allele and the endurance phenotype. However, power athletes had a higher frequency of the A-allele. In women, A/A genotype was overrepresented in international-level power group compared with non-athletes or international-level endurance athletes (23.2% vs. 16.6% or 8.8%, respectively; p < 0.05). In men, the A-allele frequency observed in power athletes or international-level power athletes was statistically different from that observed in non-athletes (51.6% or 57.8% vs. 40.4%; p < 0.009). Furthermore, men sprinters with the A-allele showed significantly faster personal best times for the 100 m than those with the C-allele (10.56 ± 0.32 s vs. 10.93 ± 0.49 s; p < 0.02). In conclusion, it was found that the AGTR2 A-allele is a candidate genetic marker for top-level power athletes.  相似文献   

Student–Mentor Relationships and Students' College Attitudes     

Chenoa S. Woods  Mariana Preciado 《Journal of Education for Students Placed at Risk》2016,21(2):90-103

Many college and SAT preparation programs are designed to improve the postsecondary success of traditionally marginalized students. In addition to academic preparation, students' social and emotional preparation is important for the transition from high school to college. Mentors can serve as role models and supports to aid students in this development. Using student survey data and hierarchical linear modeling, this study examines the influences of student–mentor relationships within an SAT program setting on students' college attitudes. Results indicate that these relationships can positively influence students' college attitudes, particularly for students who have lower baseline SAT scores. Recommendations for future research and practice are provided.  相似文献   

Reliability and validity of Yo-Yo tests in 9- to 16-year-old football players and matched non-sports active schoolboys     

Susana C. A. Póvoas  Carlo Castagna  José M. C. Soares  Pedro M. R. Silva  Mariana V. M. F. Lopes 《European Journal of Sport Science》2016,16(7):755-763

The purpose of this study was to examine the test–retest reliability and construct validity of three age-adapted Yo-Yo intermittent tests in football players aged 9–16 years (n?=?70) and in age-matched non-sports active boys (n?=?72). Within 7 days, each participant performed two repetitions of an age-related intensity-adapted Yo-Yo intermittent test, i.e. the Yo-Yo intermittent recovery level 1 children's test for 9- to 11-year-olds; the Yo-Yo intermittent endurance level 1 for 12- to 13-year-olds and the Yo-Yo intermittent endurance level 2 test for 14- to 16-year-olds. Peak heart rate (HR_peak) was determined for all tests. The distance covered in the tests was 57% (1098?±?680 vs. 700?±?272?m), 119% (2325?±?778 vs. 1062?±?285?m) and 238% (1743?±?460 vs. 515?±?113?m) higher (p?≤?.016), respectively for football-trained than for non-sports active boys aged 9–11, 12–13 and 14–16 years. The typical errors of measurement for Yo-Yo distance, expressed as a percentage of the coefficient of variation (confidence interval), were 11.1% (9.0–14.7%), 10.1% (8.1–13.7%) and 8.5% (6.7–11.7%) for football players aged 9–11, 12–13 and 14–16 years, respectively, with corresponding values of 9.3% (7.4–12.8%), 10.2% (8.1–14.0%) and 8.5% (6.8–11.3%) for non-sports active boys. Intraclass correlation coefficient values for test–retest were excellent in both groups (range: 0.844–0.981). Relative HR_peak did not differ significantly between the groups in test and retest. In conclusion, Yo-Yo intermittent test performances and HR_peak are reliable for 9- to 16-year-old footballers and non-sports active boys. Additionally, performances of the three Yo-Yo tests were seemingly better for football-trained than for non-sports active boys, providing evidence of construct validity.  相似文献
