A cross-cultural investigation into how tasks influence seatwork activities in mathematics lessons     

Ana M. Serrano 《Teaching and Teacher Education》2012

This study examined how types of tasks influenced student activities/thinking and defined the role of Seatwork in mathematics lessons. It used 60 lessons from the TIMSS videotaped Study. These data indicated that practice was the most prevalent form of tasks in the U.S. In Germany, students completed mathematical calculations after a complex problem-solving segment. In Japan, teachers combined practice of routine procedures in Seatwork with opportunities to prepare material, think about problems, and explore concepts. Findings expand our understanding of how tasks organize learning opportunities and effect how students come to understand mathematics.  相似文献   

The role of educational quality and quantity in the process of economic development     

Amparo Castelló-Climent  Ana Hidalgo-Cabrillana 《Economics of Education Review》2012

We develop a theory of human capital investment to study the effects of school quality on student choices of education, and to understand its effect on economic growth. In a dynamic general equilibrium closed economy, primary education is mandatory but there is an opportunity to continue to secondary education and beyond. High-quality education increases the returns to schooling, and hence the incentives to accumulate human capital. This is caused by two different channels: higher quality makes education accessible to more people (extensive margin), and once individuals decide to participate in higher education, higher-quality increases the investment made per individual (intensive margin). Furthermore, educational quality determines human capital composition and growth. Cross-country data evidence shows that the proposed channels are quantitatively important and that the effect of the quality and quantity of education on growth depends on the stage of development.  相似文献

Students’ conception of infinite series     

Rafael Martínez-Planell  Ana Carmen Gonzalez  Gladys DiCristina  Vanessa Acevedo 《Educational Studies in Mathematics》2012,81(2):235-249

This is a report of a study of students’ understanding of infinite series. It has a three-fold purpose: to show that students may construct two essentially different notions of infinite series, to show that one of the constructions is particularly difficult for students, and to examine the way in which these two different constructions may be built so that we may uncover ways to help students improve their understanding. The theoretical framework consists of action–process–object–schema theory and the specific model of conceptions in Balacheff’s theory of conception, knowing, and concept. Approaching the problem from these two different theoretical perspectives allows us to provide different and at the same time complementary explanations of observed phenomena. The two different infinite series constructions are, briefly stated, series as an infinite unending process of addition and series as a sequence of partial sums. Students are found to have difficulty building an understanding of series as a sequence of partial sums and thus tend to have difficulty in problem situations that require this interpretation. The study uses semi-structured interviews with 10 graduate students. The interviews explore situations that might give insight into students’ notion of the sequence of partial sums.  相似文献

Review by (non)peers as an opportunity for learning: a case study on the editorial process of papers by junior researchers / La revisión por (im)pares como instancia de aprendizaje: un estudio de casos del proceso editorial de artículos de investigadoras noveles

Abstract

We analysed the editorial process of the four articles authored by junior researchers published in the special issue The peer review process as an opportunity for learning. Our aims were to study the unfolding of the main critiques and suggestions made by reviewers in the different review rounds, as well as to explore how both authors and reviewers experienced and valued the review process. Data sources include all review reports and letters where the authors explained the changes made, and questionnaires completed by all the authors and some reviewers. The most commonly identified critiques in the reports were related to content selection and elaboration (coherence and relevance), the own author’s voice (critical positioning and caution) and attention to the reader (precision and consistency in terms and concepts, methodological clarity, writing style, legibility and formal adequacy). All four authors stated that being part of this process was rewarding and educational, highlighting the development of academic writing skills. Some reviewers emphasized the importance of reading other reviewers’ reports. We conclude by emphasizing the importance of providing junior researchers with resources that support them in communicating their research to the academic community.  相似文献

Conceptual Variation or Incoherence? Textbook Discourse on Genes in Six Countries     

Niklas M. Gericke  Mariana Hagberg  Vanessa Carvalho dos Santos  Leyla Mariane Joaquim  Charbel N. El-Hani 《Science & Education》2014,23(2):381-416

The aim of this paper is to investigate in a systematic and comparative way previous results of independent studies on the treatment of genes and gene function in high school textbooks from six different countries. We analyze how the conceptual variation within the scientific domain of Genetics regarding gene function models and gene concepts is transformed via the didactic transposition into school science textbooks. The results indicate that a common textbook discourse on genes and their function exist in textbooks from the different countries. The structure of science as represented by conceptual variation and the use of multiple models was present in all the textbooks. However, the existence of conceptual variation and multiple models is implicit in these textbooks, i.e., the phenomenon of conceptual variation and multiple models are not addressed explicitly, nor its consequences and, thus, it ends up introducing conceptual incoherence about the gene concept and its function within the textbooks. We conclude that within the found textbook-discourse ontological aspects of the academic disciplines of genetics and molecular biology were retained, but without their epistemological underpinnings; these are lost in the didactic transposition. These results are of interest since students might have problems reconstructing the correct scientific understanding from the transformed school science knowledge as depicted within the high school textbooks. Implications for textbook writing as well as teaching are discussed in the paper.  相似文献   

Who talks how to their kids about TV: A clarification of demographic correlates of parental mediation patterns     

Erica Weintraub Austin  Christopher Knaus  Ana Meneguelli 《Communication Research Reports》2013,30(4):418-430

A random telephone survey (N = 255) of Washington state parents of children between the ages of 2 and 17 assesses parents’ reported patterns of interaction with their children regarding television, along with parental viewing habits and perceptions of television content. Demographic differences in mediation and coviewing patterns, as well as parental attitudes toward television, are explored, and explanations for these differences are considered. It is concluded that education is a weak predictor of mediation levels, single parents do not differ from dual parents in attitudes about television, and that the negative relationship of income to positive mediation and use of television as a babysitter is related more to overall viewing patterns and environmental constraints, rather than to attitudinal differences. It is suggested that demographics hold little value jar explaining why and how parents hold particular attitudes or engage in particular behaviors relevant to television and parenting.  相似文献   

International University Education: An Australian Perspective   总被引：1，自引：1，他引：0

This paper attempts to explore the effectiveness of UK universities' websites. The area of branding in higher education has received increasing academic investigation, but little work has researched how universities demonstrate their brand promises through their websites. The quest to differentiate through branding can be challenging in the university context, however. It is argued that those institutions that have a strong distinctive image will be in a better position to face a changing future. Employing a multistage methodology, the web pages of 20 UK universities were investigated by using a combination of content and multivariable analysis. Results indicated ‘traditional values’ such as teaching and research were often well communicated in terms of online brand but ‘emotional values’ like social responsibility and the universities' environments were less consistently communicated, despite their increased topicality. It is therefore suggested that emotional values may offer a basis for possible future online differentiation.  相似文献
