In this study which was part of the DISUM-project, 224 ninth graders from 14 German classes from middle track schools (Realschule)
were asked about their enjoyment, interest, value and self-efficacy expectations concerning three types of mathematical problems:
intra-mathematical problems, word problems and modelling problems. Enjoyment, interest, value and self-efficacy were assessed
before and after a ten-lesson teaching unit promoting modelling competency related to the topics “Pythagoras’ theorem” and
“linear functions”. The study aimed to answer the following research questions: (1) Do students’ enjoyment, value, interest
and self-efficacy expectations differ depending on the type of task? (2) Does the treatment of modelling problems in classroom
instruction influence these variables? (3) Are there any differential effects for different ways of teaching modelling problems,
including a “directive”, teacher-centred instruction and an “operative-strategic”, more student-centred instruction emphasising
group work and strategic scaffolding by the teacher? The findings show that there were no differences in students’ enjoyment,
interest, value and self-efficacy between the three types of tasks. However, teaching oriented towards modelling problems
had positive effects on some of the student variables, with the student-centred teaching method producing the most beneficial
effects. 相似文献

This article reflects on the use of participative techniques with final-year secondary school students in one rural community in Western Kenya as an enabling tool for an outsider to both gain insider perspectives and develop a more insider role in that community by privileging and legitimating participant-driven data. Conclusions put forward the concept of the ‘inbetweener’ researcher, neither entirely inside or outside, and consider how using such methods allowed the formulation of authentic participative knowledge (co-)construction and construction of meaningful relationships in the field. 相似文献

ABSTRACTDespite the fact that feminism has recognised psychoanalysis to be a theory with direct application to the understanding of sexism for over 50 years, the application of psychoanalytic thinking to feminist activism has yet to be significantly realised. Using the work of Julia Kristeva, sexism is described as a symptom of an intolerable situation and overt forms of activism, such as street protest, that are critiqued as making demands on their subject. The third-wave tendency for deconstruction is examined as having direct implications to a concept of psychoanalytically informed activism. 相似文献

Using visual ethnography as a participatory method that places children’s and young people’s everyday experiences at the centre of research is discussed in this paper. The strengths and challenges of using participatory visual methods as a way of eliciting the thoughts, feelings and identities of young people within various education and training contexts in England are presented through the reflection of two ethnographies’ that encouraged the use of participatory visual techniques to facilitate the gathering of data. Participatory visual approaches capture meaningful child-centred and child-generated perspectives of their everyday lives in situ [Oh, Su-Ann. 2012. ‘Photofriend: Creating Visual Ethnography with Refugee Children.’ Area. 44(3): 382–288. doi:10.1111/j.1475-4762.2012.01111]. The participatory visual method is a powerful instrument within the plethora of methods available to the ethnographer. By offering reflexive accounts of doing ethnography in an unobtrusive and child respectful way the power of ethnography is revealed via its versatility. 相似文献

Residential environment index system and evaluation model established by subjective and objective methods 总被引：1，自引：0，他引：1
In this research, the residential environment index system and evaluation model were established by means of subjective and objective methods. The methodology for establishing the evaluation system for residential environment was first analyzed; then the subjective evaluation data-base was established by questionnaire survey; and at the same time, the objective evaluation data-base was constructed by Geographic Information System (GIS); and then the related equation system between subjective and objective system was developed by multiple regression analysis. This research could benefit evaluation of the residential environment quality for various purposes, and also provide important rudimentary data-base for the development and improvement of residential environment for officials. Furthermore, the index system and evaluation model established in this research could construct a strong relation between subjective evaluation and objective data; and thus could provide a comprehensive, efficient and effectiv 相似文献

Introduction The topic of this paper is language teaching methodology—and the matter of its appropriateness. A number of writers in our field have criticized language teaching methods during the last decade. Some have noted that the search for the best method is ill-advised (see, for example, Bartolome, 1994). They say that there can be no one best method. Others have 相似文献

Aluminium （Al） toxicity is one of the major limiting factors for barley production on acid soils. It inhibits root cell division and elongation, thus reducing water and nutrient uptake, consequently resulting in poor plant growth and yield. Plants tolerate Al either through external resistance mechanisms, by which Al is excluded from plant tissues or internal tolerance mechanisms, conferring the ability of plants to tolerate Al ion in the plant symplasm where Al that has permeated the plas- malemma is sequestered or converted into an innocuous form. Barley is considered to be most sensitive to Al toxicity among cereal species. Al tolerance in barley has been assessed by several methods, such as nutrient solution culture, soil bioassay and field screening. Genetic and molecular mapping research has shown that Al tolerance in barley is controlled by a single locus which is located on chromosome 4H. Molecular markers linked with Al tolerance loci have been identified and validated in a range of diverse populations. This paper reviews the （1） screening methods for evaluating Al tolerance, （2） genetics and （3） mechanisms underlying Al tolerance in barley. 相似文献

This study investigates the development of proportional and additive methods along primary and secondary school. In particular, it simultaneously investigates the use of additive methods in proportional word problems and the use of proportional methods in additive word problems. We have also studied the role played by integer and non-integer relationships between the given numbers and the nature of quantities (discrete or continuous) in the development of these phenomena. A test consisting of additive and proportional missing-value word problems was solved by 755 primary and secondary school students (from fourth to tenth grade). The findings indicate that the use of additive methods in proportional situations increased during primary school and decreased during secondary school, whereas the use of proportional methods in additive situations increased along primary and secondary school. Moreover, the presence or absence of integer ratios strongly affects this behavior, but the nature of quantities only has a small influence on the use of proportional methods. 相似文献

INTRODUCTION Geometric modelling is essential processing in computer-aided engineering (CAE) systems. Usually, the modelling of three-dimensional (3D) objects is embedded in a computer-aided design (CAD) system, which may take a huge amount of time to build entire models for CAE application. One option is the use of techniques of reverse engineering (RE) to build models from existing objects. Coordinate measuring machines (CMMs) are traditional RE tools used in the manufacturing i… 相似文献

This paper examines the place of research questions in the teaching of research methods. It describes the neglect of research questions in both methods texts and the wider academic literature, but notes that this situation is not peculiar to educational research and that similar concerns have been raised in the social sciences more widely, as well as in the humanities. It explores some possible explanations for this neglect and argues that the lack of attention paid to research questions may be related to the availability of appropriate resources, the structure and content of methods texts and the way some research is conducted and presented. Question-led methods teaching is presented as both a logical approach to the teaching of research design and data analysis and also a strategy that may help to overcome some of the weaknesses in current practice. It is argued that focusing on research questions can encourage capacity-building among new researchers and may discourage the early formation of ‘mono-method’ identities. 相似文献

Learning achievements and attitudes towards individualized learning in biology of tenth‐grade students in Israel were studied. For this purpose the subject concerned with the blood system was developed in terms of eleven self‐learning subject modules for individualized learning. Of the 557 students who participated in the study, 340 students used the individualized method whilst 214 students learned the same subject by the standard traditional method. The results indicate better achievement by students learning individually, especially average and fast students, and also girls. In the light of the results it is recommended that the individualized method be used especially in heterogeneous classes where the teacher would be free to help the slow students while average and fast students could learn without teacher assistance. 相似文献

The founding fathers of the new Jewish community in Eretz Yisrael (the Land of Israel, or Palestine) as well as many philosophers, public figures, educators and authors both in Israel and in the Diaspora were preoccupied with the image of the new Israeli Hebrew. The educational system was seen as an instrument to create the ‘new Hebrew’ (identifying with the ancient Hebrews) and to instil new values and behaviours in the young Palestinian‐born generation. During the first three decades (1981–1914) of Jewish education in Palestine, the typical teacher had neither pedagogical training nor prior experience in education, lacked the vocabulary for teaching subjects in Hebrew, and was familiar only with educational systems that differed from the one that she/he dreamed of creating. Individual teachers had no contact with one another and no institutionalised support system. They worked as ‘lone soldiers’, contending with a severe shortage of reference books, textbooks and reading material, struggling with the necessity to create a curriculum and set its priorities, and to translate and prepare material. Yet despite these tremendous difficulties, many educators did manage to realise their educational aims. What characterised these early teachers? What were the difficulties they faced? How did they manage to achieve their aims? This article attempts to answer these and other relevant questions. 相似文献

A small number of attempts have been made to take stock of the field of gender and education, though very few have taken methodology as their explicit focus. We seek to stimulate such discussion in this article by taking stock of the use of visual methods in gender and education research (particularly participatory and image-based methods). We undertake this exercise by looking at the claims researchers have made about the ways in which visual methods have advanced gender and education research, and by examining how these methods have been employed in research. We argue that the visual has become somewhat invisible in accounts of gender and education research. We conclude by considering different ways in which we might develop image-based research in the future. 相似文献

This paper examines some of the ways gifted students are said to be different from non‐gifted students by comparing the responses of 475, 9‐year‐old “gifted” students with those of 230 average‐attaining 13‐year‐old students on the same mathematical problem‐solving questions. The questions were specifically written for mathematically gifted 9 year olds as part of the World Class Tests project. The performance and approaches used by students in the two samples were found to be very similar, as was the frequency of different responses to the questions, suggesting that many of the mathematically “gifted” are not qualitatively different in their problem‐solving approaches from students of average ability, but are merely precocious. 相似文献
