Academic motivations of Yi youths in China: Classmate support and ethnic identity     

Angel Hor Yan Lai  Kin-Yu Wong  Cecilia Lai Wan Chan 《The Journal of educational research》2019,112(4):550-563

To enhance the academic achievements of Yi ethnic minority youths in rural school settings, the authors examined the effect of classmate support and the meditating role of ethnic identity in promoting their academic motivation. Cross-sectional survey data were collected from Yi youths sponsored by a philanthropic organization to attend local schools in Liangshan, rural China (n?=?657; 7–12 years old; 52% boys). Results of structural equation modelling showed that classmate support positively affected ethnic identity-commitment and ethnic identity-exploration, which then had positive impacts on three academic motivation outcomes: intrinsic motivation, extrinsic motivation-external and identified regulation, and extrinsic motivation-introjected regulation. The mediating effects of ethnic identity-exploration and ethnic identity-commitment were statistically significant, except for the pathway from classmate support to extrinsic motivation-introjected regulation via ethnic identity-commitment. The authors found that ethnic identity can be facilitated through building supportive classroom environment for positive academic motivations in Yi youths. Cross-cultural significance of this study is also discussed.  相似文献   

Analysis of the Meanings of the Antiderivative Used by Students of the First Engineering Courses     

Luis R. Pino-Fan  Vicenç Font  Wilson Gordillo  Víctor Larios  Adriana Breda 《International Journal of Science and Mathematics Education》2018,16(6):1091-1113

In this article, we present the results of the administration of a questionnaire designed to evaluate the understanding that civil engineering students have of the antiderivative. The questionnaire was simultaneously administered to samples of Mexican and Colombian students. For the analysis of the answers, we used some theoretical and methodological notions provided by the theoretical model known as Onto-Semiotic Approach (OSA) to mathematical cognition and instruction. The results revealed the meanings of the antiderivative that are more predominantly used by civil engineering students. Also, the comparison between the mathematical activity of Mexican and Colombian students provides information that allows concluding that the meanings mobilized could be shared among their communities and are not particular of their classroom or university.  相似文献   

Reduction of water evaporation in polymerase chain reaction microfluidic devices based on oscillating-flow   总被引：1，自引：0，他引：1

Producing polymeric or hybrid microfluidic devices operating at high temperatures with reduced or no water evaporation is a challenge for many on-chip applications including polymerase chain reaction (PCR). We study sample evaporation in polymeric and hybrid devices, realized by glass microchannels for avoiding water diffusion toward the elastomer used for chip fabrication. The method dramatically reduces water evaporation in PCR devices that are found to exhibit optimal stability and effective operation under oscillating-flow. This approach maintains the flexibility, ease of fabrication, and low cost of disposable chips, and can be extended to other high-temperature microfluidic biochemical reactors.  相似文献   

Job involvement in a career transition from university to employment     

Angel Blanch  Anton Aluja 《Learning and individual differences》2010,20(3):237-241

Job involvement–alienation was studied over three time points with a sample of undergraduate engineers undergoing a career transition from university to paid employment. Data from Newton and Keenan (1991) were re-analyzed under a latent growth curve modelling (LGCM) perspective, in order to provide an alternative analysis of the development of job involvement across that situational change, and to test the hypothesis that job involvement actually changed over that time period. University course satisfaction and anxiety were included as time-invariant predictors of growth, and compared to ascertain whether there would be differential effects of both predictors. The results supported the hypothesized relationships, indicating a significant growth in job involvement–alienation over time, with course satisfaction and course anxiety showing an equivalent impact on its change trajectory.  相似文献   

A Small‐Scale Randomized Efficacy Trial of the Identity Project: Promoting Adolescents’ Ethnic–Racial Identity Exploration and Resolution          下载免费PDF全文

Adolescents’ ethnic–racial identity (ERI) formation represents an important developmental process that is associated with adjustment. The Identity Project intervention, grounded in developmental theory, was designed to engage adolescents in the ERI processes of exploration and resolution. The current small‐scale efficacy trial involved an ethnic–racially diverse sample of adolescents (N = 215; M_age = 15.02, SD = .68) from eight classrooms that were randomly assigned by classroom to the intervention or attention control group. Differences between conditions in ERI exploration at Time 2 were consistent with desired intervention effects; furthermore, higher levels of ERI exploration at Time 2 predicted increases in ERI resolution at Time 3 only for youth in the treatment condition. Findings provide preliminary evidence of program efficacy.  相似文献   

Inequalities in school leavers’ labour market outcomes: do school subject choices matter?     

Cristina Iannelli  Adriana Duta 《牛津教育评论》2018,44(1):56-74

Abstract

Despite a wide international literature on the effect of vocational and general education on school-to-work transition, relatively little is known about the role of having studied specific subjects in explaining inequalities in young people’s labour market outcomes. This paper aims to fill this gap by examining differences in employment chances of young people who left education early, either at the end of compulsory schooling or at the end of secondary school. Using data from the Scottish Longitudinal Study, a large-scale linkage study created using data from administrative and statistical sources, we found little gender differences but strong parental background differences in school leavers’ employment status and type of occupation entered. Social inequalities in labour market outcomes were only partly explained by curriculum choices. Moreover, after controlling for social origin and grades, only history and business for lower-secondary leavers and maths for upper-secondary leavers were associated with a reduction in the chances of being unemployed/inactive.  相似文献   

Impact of Adding Internet Technology on Student Performance and Perception of Autonomy in Fundamentals of Electronics Course     

Carlos Andrés Rosero-Zambrano  Alba Avila  Luz Adriana Osorio  Sandra Aguirre 《Journal of Science Education and Technology》2018,27(2):177-187

The coupling of the traditional classroom instruction and a virtual learning environment (VLE) in an engineering course is critical to stimulating the learning process and to encouraging students to develop competencies outside of the classroom. This can be achieved through planned activities and the use of information and communication technologies (ICTs), resources designed to complement students’ autonomous learning needs. A quantitative analysis of students’ academic performance using final course grades was performed for a fundamentals of electronics course and we examine students’ perception of their autonomy using surveys. The students’ progress and attitudes were monitored over four consecutive semesters. The first began with the design of the intervention and the following three consisted in the implementation. The strategy was focused on the development of course competencies through autonomous learning with ICT tools presented in the VLE. Findings indicate that the students who did the activities in the VLE showed an increase in performance scores in comparison with students who did not do them. The strategy used in this study, which enhanced perceived autonomy, was associated with a positive effect on their learning process. This research shows that a technology-enhanced course supported by ICT activities can both improve academic performance and foster autonomy in students.  相似文献   

Effects of a brief but intensive remedial computer intervention in a sub-sample of kindergartners with early literacy delays     

Verna A. C. Van der Kooy-Hofland  Adriana G. Bus  Kathleen Roskos 《Reading and writing》2012,25(7):1479-1497

Living Letters is an adaptive game designed to promote children??s combining of how the proper name sounds with their knowledge of how the name looks. A randomized controlled trial (RCT) was used to experimentally test whether priming for attending to the sound-symbol relationship in the proper name can reduce the risk for developing reading problems in the first two grades of primary education. A Web-based computer program with more intensive practice than could be offered by teachers affords activities that prompt young children to pay attention to print as an object of investigation. The study focused on a sub-sample of 110 five-year-old Dutch children from 15 schools seriously delayed in code-related knowledge. Outcomes support the need for early remedial computer programs, and demonstrate that, without a brief but intensive treatment, more children from the at-risk group lack the capacity to benefit from beginning reading instruction in the early grades. With an early intervention in kindergarten, children with code-related skills delays gained about half a standard deviation on standardized tests at the end of grade 2.  相似文献   

“My Child is Your Child”: Family Behavior in a Mexican Science Museum     

Adriana Briseo‐Garzn  David Anderson 《Curator: The Museum Journal》2012,55(2):179-201

Abstract In this paper we describe the particularities of Latin American museum visitors as learners through an exploratory study that took place at Universum, Museo de las Ciencias, a science museum located in Mexico City. The exploration of the learning experiences of Latin American family groups was carried out by means of a case study approach and from a socio‐cultural theory perspective. This inquiry of 20 family groups reveals that nuances of the concept of “family,” in the Mexican context, are important in studying family learning in museum settings. The prominent roles of the extended family and interactions within family groups are discussed as intrinsic traits of a family’s museum learning. In addition, the outcomes of this study highlight the impact that the Latin American notion of educación has on museum education and research, as it encompasses issues that relate to the perpetuation of socio‐cultural values, child‐rearing, and ultimately, cultural identity.  相似文献   

International Immersion in Belize: Fostering Counseling Students’ Cultural Self-Awareness     

Shirlene Smith-Augustine  Angel Dowden  Angel Wiggins  LaCheata Hall 《International journal for the advancement of counseling》2014,36(4):468-484

International cultural immersion provides an in vivo, authentic, cross-cultural experience that can enhance multicultural awareness, knowledge and skills. This article examines the impact of an international immersion on graduate counseling students’ cultural self-awareness using a qualitative approach. Five graduate counseling students participated in a 3-week study abroad in Belize where they interacted with persons from diverse cultural backgrounds and settings. Four major cultural self-awareness themes emerged from the analysis of participants’ journals, (a) discrimination and prejudice, (b) cultural pride and appreciation, (c) cultural sensitivity, and (d) self-awareness. The findings are presented along with implications for future research and the use of international immersion as a viable experiential teaching strategy to enhance counseling students’ cultural self-awareness.  相似文献
