History of Mathematics in Korean Mathematics Textbooks: Implication for Using Ethnomathematics in Culturally Diverse School

From a multicultural perspective, this research investigated to what extent Korean mathematics textbooks use history of mathematics. The results show even though educational use of history presented in Korean mathematics textbooks may provide a rich outlook, it does not encourage a fundamental change in the educational practice of school mathematics that has traditionally been entrenched in the Eurocentric narrative of mathematics. This suggests that the mathematics textbooks were not organized effectively to promote students’ understanding of diversity. Based on the results, we discuss the implications for the development of mathematics textbook from multicultural perspectives.     

Season of birth is related to child retention rates, achievement, and rate of diagnosis of specific LD

A sizable literature has demonstrated that the achievement of children in early elementary school is related to their season of birth: Those born in summer typically perform less well than those born in the fall. A small literature indicates that more children diagnosed with specific learning disabilities (SLD) are born in the summer. We have begun to explore the possibility that the same processes may account for both outcomes. In order to better understand these processes, the standardized achievement levels and rates of diagnosis of SLD for children born during each season were studied in one geographical area of the State of Georgia served by 28 school districts. Standardized achievement scores in reading, mathematics, and science were reliably lower for those born in the summer. Furthermore, there was a strong relationship between season of birth and the rate at which children received a diagnosis of SLD. Summer-born children were diagnosed with SLD at a higher rate than their peers. Four hypotheses for both the lower performance in the general school population and the greater rate of SLD diagnosis among these children are discussed.     

Cultivating divergent thinking in mathematics through an open-ended approach

The purpose of this study was to develop a program to help cultivate divergent thinking in mathematics based on open-ended problems and to investigate its effect. The participants were 398 seventh grade students attending middle schools in Seoul. A method of pre- and post-testing was used to measure mainly divergent thinking skills through open-ended problems. The results indicated that the treatment group students performed better than the comparison students overall on each component of divergent thinking skills, which includes fluency, flexibility, and originality. The developed program can be a useful resource for teachers to use in enhancing their students’ creative thinking skills. An open-ended approach in teaching mathematics suggested in this paper may provide a possible arena for exploring the prospects and possibilities of improving mathematical creativity.     

Internet Connectedness and its Social Origins: An Ecological Approach to Postaccess Digital Divides

This study examines the influence of sociocultural factors on the level of “Internet connectedness.” The Internet Connectedness Index (ICI), composed of five items, is modified and applied to measure disparities in the ways in which people use the Internet. With a dataset of 384 randomly selected telephone survey respondents, the ICI is regressed on various social indicators. The result indicates that technological environments, social environments, and the scope and intensity of Internet-related goals significantly influence individuals' Internet connectedness. This finding highlights that even after people gain access to the Internet, the ways they incorporate the Internet into their everyday lives differ, and that the differences reflect disparities in the multiple dimensions of the social context in which individuals are situated.

Dynamic Rhetorics of Race: California's Racial Privacy Initiative and the Shifting Grounds of Racial Politics

In October 2003, Californians voted in the high-profile gubernatorial recall election and on what is referred to as the “Racial Privacy Initiative.” The Initiative sought to prohibit the gathering of racial data in education and state employment. Unlike recent such initiatives addressing California's racial laws, this one was unsuccessful: 62 percent of voters said no. This essay examines the discourse surrounding the initiative over its three-year history and traces the rhetorical dynamics that led to its defeat. The analysis details the implications of this moment for hegemonic processes in general and as they relate to the specifics of race.     

Making Science Vivid: Using a historical episodes map

Many have argued that the inclusion of the history of science in science teaching might promote an understanding of the nature of science as well as the attitudes toward science. However, its inclusion in science teaching may not have the desired effect due to the limited coverage it receives in textbooks and the limited time available for teaching. A historical episodes map (HEM) is thus developed with four storylines and more than 20 events related to the history of science and is designed to fit in with regular teaching topics. A total of 329 students in Grade 7 were involved in the experimental group and the control group. The control group was taught using the textbook only, while the experimental group was also taught using the textbook plus HEM materials and associated discussion. The intervention of such teaching lasted for a month and a half. The findings reveal that the exposure of students to HEM materials did promote the students’ understanding of the nature of science as well as their attitudes toward science.     

Extract from new understandings of teachers' pedagogic knowledge 1

Abstract

The focus of this article is a comparative review of the science curriculum for England and Wales from the perspective of recent developments in the United States of America, Australia, New Zealand and the Canadian province of Ontario. In the comparison of science curriculum documents and the language deployed, questions are raised about differences as well as commonalities among and between documents from various jurisdictions. Issues discussed include: the varying emphases upon science topics and/or intended learning outcomes; integration with other curriculum areas; the content and organization of the science curriculum; and ways of assessing students’ performances and understandings. The article draws attention to the importance of comparative analysis which informs our understanding of the effects of curriculum change, its relation to students’ achievements in science, and the need to support the development of teachers.
