This article deals with the roles of variation problems (“one problem multiple solution” and “one problem multiple changes”) as used in Chinese textbooks. It is argued that variation problems as an “indigenous” Chinese practice aim to discern and to compare the invariant feature of the relationship among concepts and solutions. This practice also aims to provide opportunities for making connections, since comparison is considered the pre-condition to perceive the structures, dependencies, and relationships that may lead to mathematical abstraction. In the first part of the article, the “indigenous” practice is discussed against its philosophical Daoism and Confucianism backgrounds. To grasp its distinctiveness, a comparison between Chinese and American textbooks is carried out. In the second part of the article, the focus is on the manner in which fraction division is articulated in an important Chinese textbook. A framework to understand variation practice is introduced and some educational implications are suggested.  相似文献

This study investigated plant and animal photographs in elementary science textbooks to discern whether there were disparities in the number of plant and animal photographs or in how those photographs were labelled. We examined the Life Science sections of two nationally syndicated (USA) textbook series. For each text, we identified the photographs with plant and/or animal content and evaluated them for two features: (1) the subject of the photograph, and (2) the specificity of the label (name) provided. We found that photographs with animal subjects were more numerous than those with plant subjects; they also represented a greater diversity of animals and had a higher instance of repetition than did plant photographs. We also found a significant naming disparity: animal photographs were three times more likely to be provided with a specific label (common name) than were plant photographs. Not only were plant photographs less likely to be provided with a specific name for the plant (e.g. orchid or dandelion), but also they were commonly identified only by the name for a plant part (such as flower or leaf) or life‐form (e.g. tree or shrub). To address the disparity revealed by this study, and to encourage student interest in and knowledge about plants, we recommend that educators go beyond textbooks to expose students to a diversity of named plants, and present plants as distinct organisms rather than as a collection of parts.  相似文献

The present study examines how gender is represented in the visuals (or illustrations) of two English Language textbook series used in most primary schools in Hong Kong. Instead of conducting frequency counts of the occurrence of male and female characters in illustrations, or the spheres of activities they engaged in as in many previous textbook studies, this study involves qualitative analyses of how visualised male and female characters are represented in the selected illustrations of the analysed textbook series, particularly but not exclusively, in terms of their hair length and clothing. The results show that representations of females were more often portrayed having long hair rather than short hair and wearing dresses rather than trousers in both line drawings and photographs. For the colour of clothing, although blue and pink are generally considered ‘masculine’ and ‘feminine’ colours, respectively, less than half and only a small percentage of the human males and females were portrayed wearing blue and pink, respectively. For non-human characters, again, colour is not always a reliable cue to their sex. Yet, they can be recognised as males and females by the generally accepted ‘masculine’ or ‘feminine’ colour and clothing items. Hence, while binary notions of gender often remained intact in their normative forms there were also other forms of representation which challenged them.  相似文献

Early childhood preservice teachers participated in a qualitative multiple case study to explore and examine the effectiveness of reform-based constructivist methods used in a mathematics methods course to change their mathematics anxiety, mathematics self-efficacy, and mathematics teachers’ efficacy beliefs. Findings indicated that instructor’s use of a variety of reform-based strategies to teach and model concepts were effective in reducing their mathematics anxiety and improving their mathematics self-efficacy and mathematics teaching efficacy beliefs. Based on these findings, it is recommended that mathematics methods course instructors use reform-based constructivist methods in their courses as outlined by the NCTM’s (2014) principles. Teacher educators must also consider carefully their attitudes and disposition toward mathematics along with the type of classroom and learning environment they establish in mathematics methods courses. They must emphasize conceptual understanding during mathematics methods courses, understand the connection between preservice teachers’ mathematics anxiety and mathematics efficacy beliefs, and integrate field experiences as well as peer teaching opportunities into mathematics methods courses.  相似文献

Students’ judgments about “what counts” as mathematics in and out of school have important consequences for problem solving and transfer, yet our understanding of the source and nature of these judgments remains incomplete. Thirty-five sixth grade students participated in a study focused on what activities students judge as mathematical, and how they make their judgments. Students completed a photo sorting activity; took, viewed, and captioned their own photos of mathematics; viewed and commented on classmates’ photos; and participated in a small group discussion. Across multiple sources of data, findings showed that students attended to two major features of photos and activities when making judgments: surface cues present in the photos, such as numbers and money, and the possibility for mathematical action. Some students looked for the possibility of mathematics, while others asked if mathematics was necessary. Students also gave higher ratings to activities with which they had personal experience. The article concludes with possible implications for practice.  相似文献

Integrating multiple theoretical frameworks, the authors examined rising first- to fourth-grade students’ mathematics utility conceptions—their knowledge and beliefs about the usefulness of mathematics, home-based mathematics engagement, and grade-level differences in mathematics utility conceptions and home engagement. Most children viewed mathematics as heavily focused on low-level mathematics operations and as learned and used primarily in school. Older children showed more awareness of mathematics as part of daily living, but still viewed mathematics as mostly school-based—more so than their younger counterparts. Results suggest that awareness of mathematics in daily life may be associated with children’s mathematics utility value (perceived usefulness of mathematics). Although children engaged in activities at home with the potential to foster mathematics development, the frequency of engagement was not related to their awareness of mathematics in daily activities. Thus, there may be untapped opportunities for young children to connect the mathematics they learn in school to their daily life.  相似文献

Photovoice is a participatory action research tool that is grounded in the literature for critical consciousness (Wang & Burris, 1997). Four creative high school girls who reported struggles with mathematics were given cameras and asked to take photographs to answer the following questions: (1) What is mathematics? (2) What is your ideal learning environment? (3) What things impede your learning of mathematics? Within-case and cross-case analyses of the photographs and interview responses were conducted. Each individual case was analyzed using the work of Belenky, Clinchy, Goldberger, and Tarule (Women’s Ways of Knowing, 1986) who investigated women’s epistemological perspectives. The girls were either silenced (disconnected from the mathematical knowledge of the teacher), received (lacked confidence to do mathematics independently), or “fragily” subjective (viewed mathematical knowledge as personal rather than imparted by the teacher) knowers of mathematics. The use of photovoice has the power to facilitate the nurturing of silence as it moves toward the “roar which is on the other side of silence” (Belenky et al., 1986, p. 4).  相似文献

A new approach to the teaching and learning of mathematics has been introduced on a phased basis in post-primary education in Ireland. As part of the OECD PISA 2012, a survey was undertaken of in-service mathematics teachers in Ireland, with the aim of gathering data on the opinions of teachers about this reform. Here, a modified version of the survey was distributed to pre-service teachers immediately before and after a four-month teaching placement to ascertain if there were differences in the views expressed by pre-service and in-service teachers in relation to the teaching and learning of mathematics, and also if there were differences expressed by the pre-service teachers before and after their placement in post-primary schools. Analysis of the results showed considerable levels of agreement between all groups, with some exceptions in relation to confidence in teaching the reformed curriculum, emphasis on various teaching and learning activities, and usage of ICT in the classroom.  相似文献

In the context of mathematics teachers’ training, the concept of dépaysement épistémologique (epistemological disorientation) emphasizes that the contact with the history of mathematics, particularly with the use of original sources, pushes aside commonplace students’ perspectives about the discipline and offers them a critical look towards mathematics’s historical, social and cultural aspects. Conceptually supported by the theory of objectivation, an emergent sociocultural theory in mathematics education, this study describes the dépaysement épistémologique lived by future mathematics teachers engaged in the reading of historical texts. A phenomenological approach allowed us to clarify various meanings associated with students’ lived experiences and a dialogical perspective provides a way to get these meanings in tension through a polyphonic narration. Our reading of this polyphonic narration suggests that dépaysement épistémologique associated with the reading of historical texts encouraged empathy from students towards the authors and their future learners, opening up the possibility for a nonviolent mathematics education.  相似文献

Research suggests that understanding new images of mathematics is very challenging and can contribute to teacher resistance. An explicit exploration of personal views of mathematics may be necessary for pedagogical change. One possible way for exploring these images is through mathematical metaphors. As metaphors focus on similarities, they can be used to express already-held perceptions about the nature of mathematics. In addition to providing a way of talking about current views of mathematics, the analogous dimensions of metaphors can prompt new ways of thinking about these images. In this article, I consider the use of metaphors as a strategy for explicating elementary teachers’ views of mathematics. I claim that the investigation of metaphors of mathematics helped create a shared communicative space and enhanced the quality of the discussion with the teachers. In particular, our exploration of the metaphor mathematics is a language encouraged a consideration of the humanistic dimensions of mathematics and contributed to a varied re-imaging of mathematics.  相似文献

Not much is known about mathematics teachers’ values, and no assessment tool is available for measuring these to get more insight into their perspectives. The goals of this study are to construct the Mathematics Teachers’ Values Questionnaire (MTVQ) and to determine mathematics teachers’ values about teaching mathematics using the MTVQ. In order to do this, data have been gathered for exploratory factor analysis (n = 637) and confirmatory factor analysis (n = 573) while developing the instrument, and a proportional stratified random sample has been formed consisting of 2226 Turkish middle and high school mathematics teachers working at schools that provide more religious education than other middle and high schools. Five components have been extracted: relevance (C1), practice (C2), information and communications technology (ICT; C3), teaching approach (C4), and consolidating (C5). One result of the study reveals the mathematics teachers emphasize the least ICT value and the most consolidating value.  相似文献

In this commentary I will address the notions of work, the need for innovation, and the role of workplace mathematics. I will then provide an overview of some of the complex issues that confront the subfield of vocational mathematics education with consequences for current and future workers, drawing in part on the work of Basil Bernstein. Finally, I will address the question of workplace research and offer some possible directions for future research, as well as implications for policy. Reflections on the articles included in this special issue will frame the discussion.  相似文献

This study investigated the association between students’ perception of the learning environment and three aspects of their mathematics attitude: ‘mathematics academic self-concept’, ‘enjoyment of mathematics’ and ‘perceived value of mathematics’. The focus was on the association of students’ mathematics attitude with four dimensions in the learning environment: the extent to which the teacher ‘motivates to exert learning effort’, ‘activates towards self-regulated learning’, ‘gives feedback and coaches’, and ‘structures and steers’. Data were obtained from an extended version of the international Trends in Mathematics and Science Study (TIMSS) of 2003. Multilevel analysis on a sample of 4354 eighth grade students in 228 classes in 119 schools in Flanders (Belgium) indicated that the learning environment plays a significant role in the enjoyment of mathematics. This while the mathematics academic self-concept and the perceived value of mathematics are insensitive for aspects in the learning environment.  相似文献

In recent years, there has been a good deal of media and academic interest in the ways in which Japanese history textbooks represent Japan's wartime past. However, the discussion has tended to revolve primarily around a number of symbolic textbook issues, such as government censorship of the term ‘aggression,’ without much consideration of divisions and conflict within the state and the ruling bloc itself. Consequently, no real analysis has emerged concerning the ways in which right-wing nationalist elements have exploited the textbook issue with the aim of reinforcing their political and cultural dominance over contemporary Japan.This article presents the Japanese history textbook controversy as an ongoing cultural and political struggle. It attempts to understand the process of the textbook struggle historically, and the relations between political parties and actors, the state bureaucracy, and right-wing nationalists. In particular, the study examines the ways in which the power of right-wing nationalism has been appropriated and negotiated by the leaders and members of the Liberal Democratic Party and bureaucrats in the Ministry of Education. It also looks at the ways in which such power has been resisted by textbook authors, educators, and certain segments of public opinion.  相似文献

This study was conducted to investigate the effectiveness of a treatment designed to improve college algebra students’ attitudes toward mathematics. Keller’s ARCS motivational design model was used as a guiding framework for the development of a motivational video, which was delivered online. The application of motivational design to improve mathematics attitudes in an online environment extends the use of motivational design. A pretest-posttest control group design was used to test the effectiveness of the treatment. The participants in this study were 43 students enrolled in a college algebra course offered at a large state university in the mid-Atlantic region of the United States. Statistically significant results were observed for improved attitudes toward mathematics.  相似文献

This paper through the theoretical framework of constructive attitude theory explores mathematics teachers’ attitudes and pedagogical strategies with reference to inclusive practice. The authors argue that though teachers may have formed positive inclusive attitudes, the translation of these into practice does not always occur and poses significant challenges.  相似文献
