This study described the conceptual understandings of 50 early childhood (Pre‐K‐3) preservice teachers about standards‐based lunar concepts before and after inquiry‐based instruction utilizing educational technology. The instructional intervention integrated the planetarium software Starry Night Backyard™ with instruction on moon phases from Physics by Inquiry by McDermott (1996). Data sources included drawings, interviews, and a lunar shapes card sort. Videotapes of participants' interviews were used along with the drawings and card sorting responses during data analysis. The various data were analyzed via a constant comparative method in order to produce profiles of each participant's pre‐ and postinstruction conceptual understandings of moon phases. Results indicated that before instruction none of the participants understood the cause of moon phases, and none were able to draw both scientific moon shapes and sequences. After the instruction with technology integration, most participants (82%) held a scientific understanding of the cause of moon phases and were able to draw scientific shapes and sequences (80%). The results of this study demonstrate that a well‐designed computer simulation used within a conceptual change model of instruction can be very effective in promoting scientific understandings. © 2007 Wiley Periodicals, Inc.

This study explored young children’s understandings of targeted lunar concepts, including when the moon can be observed, observable lunar phase shapes, predictable lunar patterns, and the cause of lunar phases. Twenty-one children (ages 7–9 years) from a multi-aged, self-contained classroom participated in this study. The instructional intervention included lunar data gathering, recording, and sharing, which integrated Starry Night planetarium software and an inquiry-based instruction on moon phases. Data were gathered using semi-structured interviews, student drawings, and a card sorting activity before and after instruction. Students’ lunar calendars and written responses, participant observer field notes, and videotaped class sessions also provided data throughout the study. Data were analyzed using constant comparative analysis. Nonparametric statistical analyses were also performed to support the qualitative findings. Results reflected a positive change in children’s conceptual understanding of all targeted concepts including the cause of moon phases, which is remarkable considering the complexity and abstractness of this spatial task. Results provided evidence that computer simulations may reduce the burden on children’s cognitive capacity and facilitate their learning of complex scientific concepts that would not be possible to learn on their own.  相似文献

Classical rhetoric's ability to inform and empower the teaching of technical writing has been for the most part ignored in technical writing textbooks. This absence is curious, given the enormous body of scholarly material affirming classical rhetoric's usefulness for that purpose. While teachers wait for textbooks with explicitly classical roots, three key concepts can provide the basic framework for incorporating classical rhetorical theory into contemporary technical writing studies.  相似文献

Fourth‐grade students’ knowledge of observable moon phases and patterns of change, as well as conceptual understanding of the cause of moon phases, was investigated before and after special instruction. Pretest and post‐test data for 48 students were used to address the research question related to observable moon phases and patterns of change. Interviews were conducted with 10 students on a post‐only basis to provide data on understanding the cause of moon phases. The researchers used the constant comparative method to analyse data. Pretest results indicate these students had not met the expectations expressed in the U.S. Science Education Standards for lunar concepts. Post‐test results reveal a very positive performance on observable moon phases and patterns of change, as well as the cause of moon phases. Interpretation and implications of these findings are provided.  相似文献

Research methods are perhaps the most difficult subject matter to teach in the graduate criminal justice curricula. This is in part due to the mix of practitioners and aspiring researchers in most criminal justice graduate departments, leading many instructors to question whether their own coverage is in line with the needs of their graduate students as well as the coverage of other instructors. Also complicating matters is that research methods textbooks are not geared specifically for the graduate level, and thus may neglect topics that are necessary for today's criminal justice graduate students. The present study addresses these concerns by providing an analysis of 11 current criminal justice research methods textbooks, as well as a survey of 36 instructors of graduate criminal justice and criminology research methods classes. Both the texts and instructors are found to place a strong focus on quantitative methods, while the textbooks tend to place a greater emphasis on qualitative methods than the instructors. Moreover, both the texts and instructors neglect topics crucial to today's criminal justice graduate student, including grant writing, article writing and critiquing, and standards for collaborative research efforts.  相似文献

This study investigates Pakistan's secondary school children's constructions of their national identity in a Pakistani school in Dubai by drawing on data collected from students and teachers from the case school and analysing national curriculum textbooks used in the school. Informed by Foucault's concepts, the article problematises how the curriculum textbooks are employed as a technology of power for inculcating national consciousness in the students. The findings suggest that Pakistan's national curriculum textbooks deploy a specific version of Islam as a major technology, which then influences other national identity signifiers in the textbooks for shaping students' national identity. The school affords a crucial space for the complex interplay of these technologies, which construct students' ethnocentric national identities, encouraging social polarisation. This has implications for Pakistan's national social cohesion as well as the potential for subverting international peaceful coexistence and working relationships, particularly in the selected overseas study context.  相似文献

Textbook analysis is seen as a major element for studying environmental education addressing pupils, image analysis being rather relevant when studying textbooks written in 11 languages. We analysed 25 textbooks from 14 countries addressed to 14–16-year-old pupils, focusing on: (1) local and foreign/global images; (2) urban/rural and nature images; (3) negative impact, human management, and the beauty of nature; and (4) men and women in images with negative and positive impact. We distinguished some trends between Western (WEc) and Eastern (EEc) European countries and non-European countries (NEc). In contrast to textbooks from EEc and NEc, which tend to show the beauty of nature with little human influence, WEc textbooks tend to exhibit more images of urban/rural landscape, of human negative impact and of human management, expressing an anthropocentric view of the environment. Men are usually more present in textbook images than women. However, some images exhibiting more women than men could be found in textbooks from WEc and EEc, but never in NEc. In negative impact pictures, men are more often present than women but NEc women are never present in such images. Women are more frequent than men in positive impact images. Results suggest that textbooks from EEc and NEc should give more emphasis to human management and urban/rural images, whereas those from WEc should give more attention to the beauty of nature. A balance in the presence of men and women in images should be a matter of greater concern by all textbooks’ authors and publishers.  相似文献

In a science methods course for elementary education majors, students investigated the phases of the moon for six weeks. The moon investigation emphasized that scientific knowledge: a) is empirically based; b) involves the invention of explanations; and c) is socially embedded. After the moon investigation, students realized that scientists make observations and generate patterns, but failed to recognize that observation could precede or follow theory building. Students could separate the processes of observing from creating explanations in their learning, but did not articulate the role of invention in science. Similarly, students valued the social dimensions of learning, but were unable to apply them to the activity of scientists. Although our teaching was explicit about students' science learning, we did not help them make direct connections between their science learning activities and the nature of science [NOS]. We provide a set of recommendations for making the NOS more explicit in the moon investigation.  相似文献

Socio-Political-Cultural Foundations of Environmental Education   总被引：1，自引：0，他引：1  
Abstract

This research project identified concepts from the social sciences that are prerequisite for understanding or analyzing environmental issues. Concepts were identified through a review of social science textbooks and educational materials and through interviews with social scientists. A list of 57 concepts was sent to a validity panel to rate each concept for clarity, acceptability to environmental education, and importance to environmental education. Means and standard deviations were calculated. Results showed that the panelists generally thought the concepts were acceptable and important to environmental education. Concepts were then revised and 6 were added based on panelists' comments.  相似文献

ABSTRACT

While global human rights knowledge has become a central facet of curricula used to shape multicultural societies and develop cosmopolitan citizenry, such knowledge is shaped by sociopolitical context. Japan has a long history of incorporating human rights concepts into its citizenship curriculum; however, this curriculum is produced in a political context where there is resistance to extending rights to minorities and the disadvantaged, and where there are renewed attempts to emphasise traditional Japanese cultural values through education. Potential tensions have been recognised, yet little has been written about educational knowledge as end product. Based partially on Basil Bernstein’s concepts, a mixed-method approach utilising computer-based analytical techniques was used to examine the structure and content of human rights knowledge within upper-secondary Contemporary Social Studies textbooks representing Japan’s official curriculum. This article will argue that the curriculum establishes an inconsistent standard toward rights that undermines respect for individuals.  相似文献

I examine the coverage of the debate about the effectiveness of offender treatment programs in 53 introductory criminology textbooks: 15 published from 1956 to 1965 and 38 published from 1983 to 1992. My data show that despite continuing skepticism in criminological research about the effectiveness of rehabilitation, most of the older texts and the most recent texts (those published from 1988 to 1992) rate treatment as effective when they take a position on the issue. My study also shows that criminology textbooks often give inadequate coverage to some of the key concepts, such as outcome measures and metaevaluation studies, in the debate about the effectiveness of rehabilitation. I conclude by discussing the implications of my findings for criminology students.  相似文献

This paper examines ways in which styles of language usage mediate attempts at describing classroom practice. The authors' particular focus centres on discursive power and they seek to illustrate some of the effects and consequences of applying certain Foucauldian concepts and analytical procedures within depictions of interactions between children and with the teacher in a nursery classroom. The paper begins by introducing an example of children's play. To this are applied analyses which stem from readings of Foucault. In so doing, it is shown how power both permeates and defines subjective positionings and where, as a consequence, individuals experience themselves as both powerful and powerless. A second example is offered in which a teacher talks to a child. The authors' analyses of this can, they believe, be perceived as a reflexive act, where the teacher's own beliefs, including her feminism, are critiqued and redefined.  相似文献

A considerable body of evidence highlights how inquiry-based science can enhance students' epistemic and conceptual understanding of scientific concepts, principles, and theories. However, little is known about how students view themselves as learners of science. In this paper, we explore primary children's images of doing science in school and how they compare themselves with ‘real’ scientists. Data were collected through the use of a questionnaire, drawing activity, and interviews from 161 Grade 4 (ages 9–10) students in Singapore. Results indicate that ‘doing science as conducting hands-on investigations’, ‘doing science as learning from the teacher’, ‘doing science as completing the workbook’, and ‘doing science as a social process’ are the images of learning science in school that most of the students held. In addition, students reported that they need to be well behaved first and foremost, while scientists are more likely to work alone and do things that are dangerous. Moreover, students often viewed themselves as ‘acting like a scientist’ in class, especially when they were doing experiments. Nevertheless, some students reported that they were unlike a scientist because they believed that scientists work alone with dangerous experiments and do not need to listen to the teacher and complete the workbook. These research findings further confirm the earlier argument that young children can make distinctions between school science and ‘real’ science. This study suggests that the teaching of science as inquiry and by inquiry will shape how students view their classroom experiences and their attitudes towards science.  相似文献

This study investigated the effect of non-traditional guided inquiry instruction on middle school students’ conceptual understandings of lunar concepts. Multiple data sources were used to describe participants’ conceptions of lunar phases and their cause, including drawings, interviews, and a lunar shapes card sort. The data were analyzed via a constant comparative method to produce profiles of each participant’s conceptual understandings and nonparametric tests also were used. Results revealed very positive performance for observable moon phases and patterns of change, as well as the cause of moon phases. Results indicated that significantly more participants shifted from drawing nonscientific shapes on the pretest to drawing scientific shapes on the post-test. Results for the drawings of moon phase sequences were similar in that significantly more participants shifted from drawing alternative waxing and waning sequences on the pretest to drawing scientific sequences on the post-test. Also, significantly more participants shifted from alternative understanding of the cause of the moon phases on the pretest to scientific understanding on the post-test. Implications of these findings and recommendations for further research are provided.  相似文献

Abstract

Engaging students in completing assigned reading material, particularly textbooks, is a challenge faced by many college professors. Further, research has demonstrated student compliance is typically low with reading course textbooks. This study explores the impact of assigning content-specific books written for popular audiences and having students participate in an associated “book club” in an undergraduate class. Survey findings indicate that most students experienced reading a book written for popular audiences as more engaging and enjoyable than textbook reading. An analysis of student reflection papers provides further evidence that this assignment and associated activities successfully engaged students with content-specific readings.  相似文献

ABSTRACT

For some time now, images in science have been an object of study in the history of science. The multiple roles that images play in scientific practice have been recognised and discussed. However, little attention has been given to science related images in educational contexts. The case of geology is all the more relevant because it is considered that it has a specific visual language that is intrinsic to its own constitution as a science. This work aims to contribute to counter this situation through the analysis of geology-related images present in textbooks for Portuguese secondary education in the period between 1836 and 1974. Temporal limits correspond to the creation of secondary education in Portugal and to the end of the Estado Novo. For this period, five textbooks were chosen and their images analysed. The place of geological subjects in the context of science teaching in Portuguese secondary education was also traced. The interpretation of the results shows that images present in textbooks had other purposes besides introducing students to the typical visual language of geology. In fact, one of their main intentions was to “shape” the student’s mind into a “rational way of thinking”.  相似文献

The research reported here derives from the general field of learner-centred teaching and learning, with specific reference to undergraduate chemistry. It documents the use of student-generated questions as diagnostic of their willingness to engage in classroom interactions. It explores four ways of gathering students' written questions and their relative effectiveness. It examines students' capacity to design and present 'quality questions' during phases of their learning and the extent to which these questions are indicative of particular styles of interaction in the classroom, both with tutors and with other students. The results are drawn from data collected through written questions posted into a question box, the 'hits' recorded on a computer software system, and through one-to-one interviews with a sample of 32 students. The results provide an opportunity to discuss the quality of interactions within fairly formalized systems of teaching and learning of chemistry in a university setting and to suggest further research required in this field.  相似文献

This article examines the use of archive pictures (paintings, photographs and engravings) in school textbooks, in the controversial setting of the Key Stage 3 (11–14) and Key Stage 4 (14–16) topics of the American West and the Native Peoples of North America, where pictorial images have created powerful stereotypes. Attention is drawn to the 1994 Schools Curriculum and Assessment Authority's report on history textbooks, which criticized the lack of supporting information for archive pictures. Textbooks written prior to the 1994 report are contrasted with those written since. It is noted that despite the report and recent historical interest in the study of representations, there has been little improvement in textbook design. The methods of analysis that should be used on paintings, photographs and engravings are explained in some detail, and the effect of not providing the essential background for pupils to develop a reasoned discussion of their value as historical evidence is demonstrated through a number of case-studies. Finally a checklist is provided for authors, publishers, teachers, trainee teachers and teacher educators to help them incorporate essential background material, in order to ensure that pupils can bring the same critical awareness to pictorial images as they have become accustomed to with written sources.  相似文献

This study focused on the conceptual understandings held by 78 preservice elementary teachers about moon phases, before and after instruction. Participants in the physics groups received instruction on moon phases in an inquiry‐based physics course; participants in the methods group received no instruction on moon phases. The instructive effect of two different types of preinstruction interviews also was compared. The instruction on moon phases used in the study is from Physics by Inquiry by Lillian McDermott. In the study, the method of inquiry followed a qualitative design, involving classroom observations, document analysis, and structured interviews. Inductive data analysis identified patterns and themes in the participants' conceptual understanding. Results indicate that without the instruction, most preservice teachers were likely to hold alternative conceptions on the cause of moon phases. Participants who had the instruction were much more likely to hold a scientific understanding after instruction. The instruction appears to be more effective in promoting a scientific understanding of moon phases than instruction previously reported in the literature. It also appears that using a three‐dimensional model or making two‐dimensional drawings during the preinstruction interviews does not have instructive value. © 2002 Wiley Periodicals, Inc.

教科书作为一种合法性知识文本,是主流意识形态的承载物。母亲角色是女性重要的身份,分析教科书中的母职图像,可以呈现教科书所建构的理想母职观念及其背后的社会权力关系。本研究运用文本分析法对我国X版小学语文教科书的选文和插图进行分析,以探究教科书对理想母职的再现策略及其背后所建构的母职意识形态。笔者发现:第一,X版小学语文教科书中的母亲形象呈现出“家庭化”和“弱势化”两大特征。第二,X版小学语文教科书通过女性刻板印象、母职的社会公共角色缺失以及母职符号化等叙事方式建构了当前理想的母职观念。第三,X版小学语文教科书通过“惩戒凝视”和“自我标准化”这两种策略实现了理想母职的再生产。最后,根据研究发现对小学语文教科书的母职呈现提出建议,以期能够对小学语文教科书的编写提供一定的借鉴。  相似文献
