We investigated relationships between students’ perceptions of parental involvement in schooling, their Spanish classroom environment and student outcomes (attitudes and achievement). Modified Spanish versions of the What Is Happening In this Class?, Test of Spanish-Related Attitudes-L1, a parental involvement questionnaire and a Spanish achievement test were administered to 223 Hispanic Grade 4–6 students in South Florida. The factor structure and internal consistency reliability of the questionnaires was supported. Strong associations were found for parental involvement with students’ learning environment perceptions and student outcomes, and for Spanish classroom environment with student outcomes. When the unique and common variances in student outcomes explained by the classroom environment and the home environment were examined, the home environment was more influential than the classroom environment in terms of students’ attitudes, but the classroom environment was more influential than the home environment in terms of achievement. 相似文献

As is now widely established, sexuality is a historically and culturally specific social construction. In Mexico, such construction has been dominated by different institutions and discourses at different times. From pre-Hispanic times to today, this article traces the ideas that main institutions, like the Catholic Church, have ingrained in Mexican sexual culture and shows how they have changed over time. At present, sexuality has become a contested arena?like never before?in which very diverse discourses contend for hegemony. Formal sex education has not been alien to this debate, in which religion, medicine, gender equity discourses and ethics seem to have a differential input in curricula and textbooks. This article discusses the expression of this tension in formal sex education in Mexico. 相似文献

ABSTRACTPurpose: Educational farms (EFs) serve a number of social and economic functions and are part of the debate about new learning environments, multifunctional agriculture and firm diversification. Through the analysis of a case study, this paper aims to identify strengths and weaknesses, opportunities and threats (SWOT) of EFs and key factors for setting a development strategy.Design/Methodology/Approach: A direct survey to EFs in Molise region (IT) was implemented during April-May 2017 and results were assessed following a SWOT approach.Findings: Strong motivation and connection with agritourism activities are strengths of EFs in the region; small size, unskilled staff, lack of structured educational pathways, and limited profitability are the main weaknesses. Farms opportunities come from a territory rich in rural landscapes, environmental resources, and typical food products, and from a growing demand for educational tourism. Obstacles are in the institutional sphere and due to the absence of regional networks. Based on SWOT findings, key factors for EFs development are discussed.Practical implications: EFs development requires innovative educational and managerial tools, a more concerted and proactive role for multiple stakeholders, and the implementation of a network approach. Study findings solicit actions from public institutions and advisory services to improve farmers’ skills.Theoretical implications: The paper contributes to the theoretical debate about the need for a multidisciplinary approach in dealing with the analysis of EFs.Originality/Value: The analysis underlines the importance of internal and external drivers in stimulating farms and institutions to support diversification strategies, rural development and transformation processes in inner areas. 相似文献

The paper aims to further explore the role that culture plays in the provision and assimilation of sex education among Latina immigrants in the USA. To accomplish this, researchers conducted focus groups and interviews with 30 women from Central and South America who have lived in the USA for at least five years. Participants were asked to reflect on their experience with sex education in their home country and in the USA, and to assess how their attitudes towards sex education may impact their behavioural choices as parents and as sexually-active women. The findings demonstrate a wide range of views that did not follow patterns by common demographical proxy variables, suggesting that such variables are not enough to predict adoption of new cultural values that are different from their family's traditional norms. Instead, adherence to traditional cultural beliefs appeared to be a better predictor of attitudes and behaviours. 相似文献

People of Latin American descent make up the largest and fastest-growing minority group in the USA. Rates of pregnancy, childbirth, and sexually transmitted infections among people of Latin American descent are higher than among other ethnic groups. This paper builds on research that suggests that among families of Latin American descent, mothers have a particularly strong influence on the sexual attitudes and behaviours of their children, yet that parents of Latin American descent communicate less with their children about sex than parents of other ethnic groups. It examines the messages about sex women received as children in their countries of origin, and how these messages and their views of the USA influence the sexual education women provide for their children. On the basis of data from focus groups, we suggest that, in spite of the persistence of sexual silence, some women's self-reflective analyses of their own sexual education as well as their views of the USA as a sexually more open society contribute to their views of silence as dangerous and trigger more open communication with sons and daughters. Mothers hope to break the cycle of unwanted pregnancy by speaking with daughters about the consequences of menstruation and with sons about contraception. 相似文献

AbstractThis study analyses whether narrative skill and the perception of values/countervalues among students in primary school vary according to the structure (narrative vs non-narrative) of the episodes of fiction viewed, the grade age (third and sixth, 8–12 years old), sex and attentional level. With this purpose in mind, quantitative and qualitative methodologies were implemented. The most noteworthy results include the higher narrative skill and perception of values/countervalues of students in the sixth grade of primary school and those who viewed an episode with a narrative structure. The conclusion is that when addressing narrative skills and the education in values/countervalues from the formal and informal spheres, special importance should be attached to the structure of the fiction contents, given that it can to some extent help students make the messages meaningful in terms of values and countervalues. 相似文献

To date, assessment validity research on non-native English speaking students in the United States has focused exclusively on those who are presently English language learners (ELLs). However, little, if any, research has been conducted on two other sizable groups of language minority students: (a) bilingual or multilingual students who were already English proficient when they entered the school system (IFEPs), and (b) former English language learners, those students who were once classified as ELLs but are now reclassified as being English proficient (RFEPs). This study investigated the validity of several standards-based assessments in mathematics and science for these two student groups and found a very high degree of score comparability, when compared with native English speakers, for the IFEPs, whereas a moderate to high degree of score comparability was observed for the RFEPs. Thus, test scores for these two groups on the assessments we studied appear to be valid indicators of their content knowledge, to a degree similar to that of native English speakers. 相似文献

This article examines nonmathematical linguistic complexity as a source of differential item functioning (DIF) in math word problems for English language learners (ELLs). Specifically, this study investigates the relationship between item measures of linguistic complexity, nonlinguistic forms of representation and DIF measures based on item response theory difficulty parameters in a state fourth-grade math test. This study revealed that the greater the item nonmathematical lexical and syntactic complexity, the greater are the differences in difficulty parameter estimates favoring non-ELLs over ELLs. However, the impact of linguistic complexity on DIF is attenuated when items provide nonlinguistic schematic representations that help ELLs make meaning of the text, suggesting that their inclusion could help mitigate the negative effect of increased linguistic complexity in math word problems. 相似文献
