Secondary School Students’ Errors in the Translation of Algebraic Statements     

Marta Molina  Susana Rodríguez-Domingo  María Consuelo Cañadas  Encarnación Castro 《International Journal of Science and Mathematics Education》2017,15(6):1137-1156

In this article, we present the results of a research study that explores secondary students’ capacity to perform translations of algebraic statements between the verbal and symbolic representation systems through the lens of errors. We classify and compare the errors made by 2 groups of students: 1 at the beginning of their studies in school algebra and another 1 completing their studies on algebra in compulsory education. This comparison allows us to detect errors which require specific attention in instruction due to its persistence and to identify errors that disappear as students advance in their study of algebra. The results and conclusions have a pedagogic value to inform instruction and also lead to backed conjectures and research questions to push forward research on student’s translation capacity and students’ knowledge of algebraic symbolism.  相似文献   

Undoing diversity: knowledge and neoliberal discourses in colleges of education     

Claudia Matus  Marta Infante 《Discourse: Studies in the Cultural Politics of Education》2011,32(3):293-307

In this article we analyze discourses of ‘diversity’ in colleges of education in Chile. We contend that the use of discourses of diversity, as reproducing the separation between mainstream subjectivities and those uncontained by the category of normal, is one of the ways universities align themselves with the rules of a democratic society, based on ideas of multicultural understandings and tolerant communities proliferated by inter-governmental institutions such as the Organization for Economic Cooperation and Development (OECD) and others. Our interest is to question the marginalization of cultural politics through the intensification of these discourses. At the same time, we explore the relations between the advancement of neutral discourses of difference and the value-free practices expressed in neoliberal educational agendas. We use discourse analysis to read interviews with future teachers. We understand students’ narratives as perpetuating normative ways of thinking and legitimating those knowledges promoted by institutional curricula.  相似文献

Background

Numerous data suggest that aerobic-type exercise improves lipoprotein-lipid profiles, cardiorespiratory fitness and body composition in young women. The aim of this study was to evaluate the biological response to high-low impact aerobic fitness among young women.

Materials and methods

Thirty-four young women aged 22 (19-24) years were divided into three groups: underweight (N = 10), normal weight (N = 12) and overweight (N = 12). Aerobic capacity, anthropometry and body composition together with complete blood count and lipid profile were determined before and after completion of a 12-week-long training period.

Results

The training programme caused a significant decrease in weight (by 4.3 kg, P = 0.003), body mass index (by 1.3 kg/m², P = 0.003), free fat mass (by 2.1 kg, P = 0.002), total body water (by 0.4 kg, P = 0.036), percentage of fat (by 3 percent points, P = 0.002), all analyzed skinfolds thicknesses, as well as the lipid profile in overweight group, and no changes in normal weight group. Significant changes in weight (by 4.2 kg, P = 0.005), body mass index (by 0.9 kg/m², P = 0.005), crus skinfold thickness (by 3.3 mm, P = 0.028), and in maximum oxygen uptake (by 2.49 mL/kg/min; P = 0.047) were observed among underweight women. No change in total blood count was observed in all groups.

Conclusion

Twelve-week-long fitness training programme of two alternating styles (low and high impact) has a beneficial effect on overweight young women.Key words: body composition, physical fitness, overweight, women  相似文献   

How cognitive,metacognitive, motivational and emotional self‐regulation influence school performance in adolescence and early adulthood     

Karin Bakracevic Vukman  Marta Licardo 《Educational studies》2010,36(3):259-268

This contribution aims to examine how different areas of self‐regulation are related to academic achievement in adolescents and young adults. The study involved participants, drawn from following age groups: 14–15, 17–18 and 22–23. In order to get information about cognitive, metacognitive, motivational and emotional aspects of self‐regulation, self‐report questionnaires were used. Differences between age‐groups revealed following tendency: there has been a decrease in all fields of self‐regulation from age of 14 (end of primary school) to the age of about 18 years (end of secondary school), and then results slowly improved to the age of about 22 years (students of undergraduate studies). The results obtained are mirroring perceived competence of self‐regulation and differ from the results concerning metacognitive accuracy. Metacognitive self‐regulation persists as an important predictor of school achievement at all developmental levels, and the motivational self‐regulation has significant impact on performance in the first and second age group.  相似文献

Full-income and price elasticities of demand for German public theatre     

Marta Zieba 《Journal of Cultural Economics》2009,33(2):85-108

This article provides estimates of price and income elasticities of demand for German public theatre, using a large and reliable data set for 178 theatres over 40 years (1965–2004). It is posited that the consumption of the performing arts is a time-intensive activity for which both a theatre ticket and leisure time are necessary. Thus, the impacts of ‘full-income’ (‘leisure time income’ added to disposable income) and the price of leisure time on theatre attendance are examined. The findings indicate that the demand for the performing arts is own-price inelastic. The disposable income elasticity is significant, positive and equals approximately one. In contrast, the full-income elasticity is well above one and greater than usual income elasticity indicating that the performing arts are a luxury good when leisure time income is included in the consumer’s budget. The positive full-income effect is, however, offset by the negative price of leisure effect indicating that leisure time is a complement for the performing arts. Additionally, three objective quality characteristics of theatrical productions which can positively influence theatre demand are examined.

National and institutional policies on open access are not yet fully established in the United States because of the manner in which the open access movement has evolved. In this report, the authors illustrate how the open access movement has evolved within each community libraries, universities, publishing companies, government agencies, the professoriate, public interest groups, and the U.S. Congress and note what trends now are beginning to emerge.  相似文献   

Making Sense of What Students Know: Examining the Referents, Relationships and Modes Students Displayed in Response to a Decimal Task     

Barbara M. Moskal  Maria E. Magone 《Educational Studies in Mathematics》2000,43(3):313-335

Written tasks that request an explanation can offer detailed information concerning students' knowledge to the classroom teacher. The examination of students' written responses for the mathematical systems that are employed (referents), the connections that are displayed (relationships) and the communication methods that are utilized (modes) provides evidence that suggests how the student is making sense of a problem. The purpose of this article is to describe the constructs of referents, relationships and modes and to illustrate how these constructs may be reflected in students' written responses to a decimal task that requests an explanation. This article will also examine sets of responses from two classrooms using the proposed framework to illustrate the type of information that teachers may acquire through the application of this framework. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献
